Fellow  ShareholderS

2008 was another very successful year for InterDigital. We delivered solid 

financial  results  and  value  to  our  shareholders  through  our  continued 

success in technology development and licensing. We further enhanced the 

value of our patent portfolio with successful research and development, and 

we refined our strategic plan to address the evolving wireless marketplace. 

As a result, we have greater financial strength entering a new year than in 

any point in our history. We will use our creative and talented engineers 

who drive our innovation engine, our rich portfolio of patented inventions, 

and our solid financial position to generate even greater results in 2009.

in 2008, the Patent licensing Business Shines Again 
Completing patent licensing agreements with top-tier mobile device manufacturers is a 
key value driver for InterDigital. We made significant progress in 2008 toward realizing 
our goal of deriving value from every 3G device sold. 

In November, we resolved our long-running 2G and 3G licensing disputes with Samsung, 
culminating in an agreement under which InterDigital is scheduled to receive $400 million 
over an 18-month period. This financially significant agreement with a top-tier mobile device 
manufacturer provides concrete evidence of the value of our patent portfolio. With Samsung 
under license, we now have 50% of the 3G handsets sold worldwide under license, another 
indicator of the strength of InterDigital’s patent portfolio and licensing program.

In addition to Samsung, we added ASUSTeK, Pegatron, iWow, ModeLabs, and Global Wireless 
as patent licensees in the last year. These new licensees address emerging market segments, 
offer differentiated products, and deploy unique marketing approaches. Over time, they 
hold the promise of providing substantial incremental revenue to InterDigital.

Successfully driving the Wireless Future
In 2008, we built on our innovation heritage, investing in technologies that will drive 
future opportunities for InterDigital. A number of our new inventions were accepted as 
contributions into the standards that will define future releases of both 3G technologies 
and LTE. At this point, we believe we have a portfolio of inventions critical for future 
patent licensing with both existing and new licensees. Equally important, we expect our 
portfolio of patents to grow over time.

We also made great progress toward commercializing our Media Independent Handover 
(MIH) offering, which enables users to roam seamlessly across different wireless networks. 
At the recent Mobile World Congress in Barcelona, we demonstrated our MIH middleware 
loaded on an off-the-shelf handset, delivering uninterrupted data streaming when switching 
between live 3G and WiFi networks. The interest in this technology is very strong.

2       I N T E R D I G I TA L  2 0 0 8   A R

vWe also remain in the forefront in developing enabling technologies that will drive the 
future generation of wireless networks, where users will be connected all the time, 
and to many things. Movement from a network of connected people to a network of 
connected things (both people and machines) requires inventive solutions to address 
security, quality of service, and seamless connectivity. InterDigital is working diligently 
both in its labs and in the standards bodies to make these future networks a reality. 
Indeed, to build on our strengths, in early 2009 we committed to expand our technology 
development and licensing business through targeted new investment in both cellular 
and non-cellular technologies.

Realigning the Modem Product Business
In 2008, we sought to increase revenue contribution from both sales of SlimChip modem 
IP and baseband chips. Our IP sales hit our goals, as our technology licensees began 
to ship meaningful volumes of 3G chips containing our technology. We expect ongoing 
contributions from our technology solutions revenues in 2009.

We  also  made  tremendous  progress  toward  commercializing  our  SlimChip  mobile 
broadband modem, including signing some initial agreements for the high-performance 
baseband  chip.  However,  the  baseband  modem  market  has  undergone  significant 
commoditization since we began this initiative.

Following a thorough strategic analysis of the market and the position of our SlimChip 
mobile broadband modem, we decided in early 2009 to discontinue further development 
of  the  modem.  Nevertheless,  we  will  be  seeking  to  har vest  our  investment  through 
technology licensing.

There is no question that the SlimChip is a clear technology success. Everyone who 
contributed to its development should feel proud of their achievement. However, being 
competitive on a long-term basis in the fast-changing baseband market would have 
required a significant investment to scale the business and, given market dynamics, the 
risk of following that path became unacceptable. Focusing our business direction will 
result in substantially higher levels of profitability for InterDigital.

Financial Results
InterDigital achieved solid performance despite a weak economic environment in 2008. Net 
income increased to $26.2 million, or $0.57 per diluted share, compared to $20.0 million, or 
$0.40 per diluted share, in 2007. 

Although the current environment is uncertain and no market is completely immune to 
the dynamics of the global economy, the structure of our royalty stream provides significant 
insulation from market swings. Specifically, licenses with fixed revenue recognition accounted 
for 43% of our recurring revenue in fourth quarter 2008. The other major component of that 
revenue stream is unit-based revenue, which fluctuates with sales by our licensees. The 
fixed component of our recurring revenue provides stability, which is particularly helpful 
near term, while the unit-based revenue provides opportunity for growth from our existing 
licensees as 3G market volume expands over time. With the addition of Samsung in first 
quarter 2009, we expect that the fixed component of our recurring revenue will increase to 
about 60% in first quarter 2009. This provides better visibility in our revenues in the near 
term, while allowing us to participate in the growth of this dynamic market as well.

Our balance sheet also remains very strong. During a period of significant investment in 
our business and stock repurchases, we ended fourth quarter 2008 with a strong $141.7 
million in cash and short-term investments, even after completing a $100 million stock 
repurchase program for a total of 4.8 million shares, or about 10%, of our common shares. 
In addition, under a recent license agreement, Samsung is obligated to pay $400 million to 
us. As an expression of confidence in the potential of our patent licensing programs, the 
Board authorized a new $100 million share repurchase program in March 2009.

While weak global economic conditions might continue to affect industry handset sales near 
term, we remain optimistic about the fundamental growth prospects for the 3G handset 
market. In addition, we remain confident in our ability to add major new licensees, which 
could significantly increase our royalty revenues.

vvvvvvvinvesting for 2009 and Beyond
Our primary goal for the patent licensing business in 2009 will be to continue to expand 
our  licensee  base,  both  with  the  top  five  handset  manufacturers  and  other  market 
participants.  We  will  also  continue  to  invest  in  our  future.  InterDigital  is  ver y  well 
positioned to execute on both goals.

The 3G case with Nokia at the International Trade Commission is moving forward in what 
we believe to be a positive manner. We remain on target for the evidentiary hearing in May 
2009 and for an initial determination from the Administrative Law Judge in August 2009. 
Given the strength of our position in the case, we believe that we will either secure a 
favorable settlement with Nokia or a favorable decision, either of which would be a significant 
achievement in our primary goal and drive even greater value for our shareholders.

Further investment in new technology and inventions will be an overriding objective for 
2009. Building on our strong financial position and innovation legacy, we will broaden our 
advanced research and development beyond the evolution of cellular to include other 
wireless technologies. These technologies will shape how people will work, live, and play 
in the future.

In a time when other companies are financially challenged and cannot invest in future 
technologies, InterDigital sees a window of opportunity to leap ahead of others in the 
market. More importantly, we have the imagination to envision a new wireless world and 
the talent to solve the complex technical challenges to make new systems a reality in the 
future. With our financial strength, we will seek to capitalize on these opportunities and 
drive ever greater value for our shareholders.

2008 was a great year for InterDIgItal, anD we expect 

even more In 2009.

Thank you for your ongoing support.

Tomorrow

Our path forward is clear. InterDigital will continue to bring innovations for the wireless 
world of the future, help define the standards, and license our patented inventions 
— with a much stronger financial position, direction, and purpose than ever before. 
We are working to drive the cellular industry’s move to the next generation wireless 
standard, Long Term Evolution or LTE, a new air interface that will provide even higher 
data rates, greater capacity, and improved coverage.

We are also expanding our wireless inventions in areas beyond cellular, to more explorative 
research and development that might someday revolutionize the entire wireless industry.

Part of our push beyond cellular leads to a future Network of Networks, where billions 
of users enjoy rich and secure multimedia connections while moving seamlessly across 
different technologies. We will help create the Internet of Things, with trillions of wireless 
sensors  connecting  people  to  machines  and  machines  to  machines,  revolutionizing 
everything we do, from healthcare to banking to entertainment to social networking. 

Balancing near term core research and development with longer term projects is the 
foundation for deriving steady revenue growth and profitability. Ongoing patent licensing, 
breakthrough technology transfers, strategic R&D partnerships, and seeding product 
opportunities will all contribute to our growth.

Our financial strength enables us to invest in long-term innovation — unlike many others 
in the industry in this current uncertain environment — and exploit a unique window of 
opportunity to build technology for tomorrow’s wireless world.

Wireless Communications Industry Overview

Participants  in  the  wireless  communications  industry  include  OEMs,  semiconductor 
manufacturers,  ODMs,  and  a  variety  of  technology  suppliers,  applications  developers,  and 
operators  that  offer  communications  services  and  products  to  consumers  and  businesses. To 
achieve  economies  of  scale  and  allow  for  interoperability,  products  for  the  wireless  industry 
have  typically  been  built  to  wireless  Standards. These  Standards  have  evolved  in  response  to 
large  demand  for  services  and  expanded  capabilities  of  mobile  devices. Although  the  cellular 
market  initially  delivered  voice-oriented  and  basic  data  services  (commonly  referred  to  as 
Second Generation or 2G), over the past five years, the industry transitioned to providing voice 
and  multimedia  services  that  take  advantage  of  the  higher  speeds  offered  by  the  newer 
technologies  (commonly  referred  to  as Third  Generation  or  3G).  Concurrently,  non-cellular 
wireless  technologies,  such  as  IEEE  802.11,  have  emerged  as  a  means  to  provide  wireless 
Internet  access  for  fixed  and  nomadic  use.  Industry  participants  anticipate  a  proliferation  of 
converged devices that incorporate multiple air interface technologies and functionalities, and 
provide  seamless  operation. As  an  example,  such  converged  devices  may  provide  seamless 
operation between a 3G network and a WLAN network.

Over  the  course  of  the  last  ten  years,  the  cellular  communications  industry  has  experienced 
rapid  growth  worldwide. Total  worldwide  cellular  wireless  communications  subscriptions  rose 
from slightly more than 320 million at the end of 1998 to approximately 4.0 billion at the end of 
2008.  In  several  countries,  mobile  telephones  now  outnumber  fixed-line  telephones.  Market 
analysts  expect  that  the  aggregate  number  of  global  wireless  subscriptions  could  exceed  5.6 
billion  in  2013.  In  June  2008,  Strategy Analytics,  Inc.  forecasted  1.4  billion  total  handset  sales 
for  2009.  Recently,  Strategy Analytics,  Inc.  lowered  their  forecast  for  2009  handset  sales  by 
20%. The  following  table  includes  the  recent  forecast  for  2009  and  the  June  2008  forecast  for 
2010 through 2013, the latest forecast available for that period.

The growth in new cellular subscribers, combined with existing customers choosing to replace 
their  mobile  phones,  helped  fuel  the  growth  of  mobile  phone  sales  from  approximately  
168  million  units  in  1998  to  almost  1.2  billion  units  in  2008. We  believe  the  combination  of  a 
broad  subscriber  base,  continued  technological  change  and  the  growing  dependence  on  the 
Internet,  e-mail  and  other  digital  media  sets  the  stage  for  continued  growth  in  the  sales  of 
advanced  wireless  products  and  services  over  the  next  five  years. While  recent  market  forces 
and  a  global  economic  downturn  may  contribute  to  a  decline  in  total  handset  sales  for  2009, 
analysts  continue  to  predict  that  the  shift  to  advanced  3G  devices  will  continue  to  increase 
sales  in  that  category.  For  these  same  reasons,  shipments  of  3G-enabled  phones,  which 
represented approximately 25% of the market in 2007, are predicted to increase to approximately 
80% of the market by 2013. Moreover, recent advances in 3G technologies that support devices 
offering higher data rates have met with rapid consumer uptake.

In  addition  to  the  advances  in  digital  cellular  technologies,  the  industry  has  also  made 
significant advances in non-cellular wireless technologies. In particular, IEEE 802.11 WLAN has 
gained  momentum  in  recent  years  as  a  wireless  broadband  solution  in  the  home  and  office 
and  in  public  areas.  IEEE  802.11  technology  offers  high-speed  data  connectivity  through 
unlicensed  spectra  within  a  relatively  modest  operating  range.  Since  its  introduction  in  1998, 
semiconductor  shipments  of  products  built  to  the  IEEE  802.11  Standard  have  shipped  nearly  
1  billion  units  cumulatively  through  2008. Analysts  forecast  that  these  cumulative  shipments 
may reach 4 billion by 2012. In addition, the IEEE wireless Standards bodies are creating sets of 
Standards  to  enable  higher  data  rates,  provide  coverage  over  longer  distances  and  enable 
roaming. These Standards are establishing technical specifications for high data rates, such as 
IEEE 802.16 (WiMAX), as well as technology specifications to enable seamless handoff between 
different air interfaces (IEEE 802.21).

Evolution of Wireless Standards

Wireless  communications  Standards  are  formal  guidelines  for  engineers,  designers, 
manufacturers  and  service  providers  that  regulate  and  define  the  use  of  the  licensed  radio 
frequency  spectrum  in  conjunction  with  providing  specifications  for  wireless  communications 
products. A  primary  goal  of  the  Standards  is  to  assure  interoperability  of  products,  marketed 
by  multiple  companies,  built  to  a  common  Standard. A  number  of  international  and  regional 
wireless  Standards  Development  Organizations  (“SDOs”),  including  the  ITU,  ETSI, TIA  (USA), 
ATIS  and  ANSI,  have  responsibility  for  the  development  and  administration  of  wireless 
communications Standards. New Standards are typically adopted with each new generation of 
products, are often compatible with previous generations of the Standards and are defined to 
ensure interoperability.

SDOs typically ask participating companies to declare formally whether they believe they hold 
patents or patent applications essential to a particular Standard and whether they are willing to 
license those patents on either a royalty-bearing basis on fair, reasonable and nondiscriminatory 
terms  or  on  a  royalty-free  basis. To  manufacture,  have  made,  sell,  offer  to  sell  or  use  such 
products on a non-infringing basis, a manufacturer or other entity doing so must first obtain a 
license from the holder of essential patent rights. The SDOs do not have enforcement authority 
against entities that fail to obtain required licenses, nor do they have the ability to protect the 
intellectual property rights of holders of essential patents.

Digital Cellular Standards

The  defined  capabilities  of  the  various  technologies  continue  to  evolve  within  the  SDOs. 
Deployment  of  3G  services  allows  operators  to  take  advantage  of  additional  radio  spectrum 
allocations and through the use of higher data speeds than 2.5G, deliver additional applications 
to  their  customers.  Operators  began  to  deploy  3G  services  in  2000. The  five  specifications 
under  the  3G  standard  (generally  regarded  as  being  the  ITU “IMT-2000”  Recommendation) 
include the following forms of CDMA technology: FDD and TDD, (collectively referred to in the 
industry as WCDMA), and Multichannel CDMA (cdma2000 technology). In addition, TD-SCDMA, 
a Chinese variant of TDD technology, has been included in the Standard’s specifications.

The  principal  Standardized  digital  cellular  wireless  products  in  use  today  are  based  on TDMA 
and CDMA technologies with 3G capable-products beginning to replace 2G-only products. The 
Standardized 2G TDMA-based technologies include GSM, TIA/EIA 54/136 (commonly known as 
AMPS-D,  United  States-based TDMA,  which  is  currently  being  phased  out  in  conjunction  with 
the  U.S.  FCC-mandated  conversion  from  analog-based  cellular  service),  PDC,  PHS,  DECT  and 
TETRA.  Of  the TDMA  technologies,  GSM  is  the  most  prevalent,  having  been  deployed  in 
Europe, Asia, Africa,  the  Middle  East,  the Americas  and  other  regions.  In  2008,  approximately 
70% of total mobile device sales conform to the 2G and 2.5G TDMA-based Standards. WCDMA-
enabled  devices  accounted  for  an  additional  15%  of  total  sales. Thus,  the  combined  sales  of 
GSM-enabled  devices  and  devices  with  3G WCDMA  technology  accounted  for  approximately 
85% of worldwide handset sales.

Narrowband  2G  CDMA-based  technologies  include TIA/EIA-95  (more  commonly  known  as 
cdmaOne)  and  cdma2000  technologies  and  serve  parts  of  the  United  States,  Japan,  South 
Korea  and  several  other  countries.  Similar  to  the TDMA-based  technologies,  the  CDMA-based 
technologies are migrating to 3G. In 2008, about 15% of worldwide handset sales were based 
on these 2G / 2.5G CDMA technologies plus its 3G evolution.

The Standards groups continue to advance the performance and capabilities of their respective 
air  interfaces.  Chief  among  the  most  recent  enhancements  are  High  Speed  Downlink  Packet 
Access  and  High  Speed  Uplink  Packet Access  (HSDPA/HSUPA),  an  evolution  of WCDMA,  and 
1xEV-DO. At year end 2008, over 150 operators had launched HSDPA networks.

4       I N T E R D I G I TA L  2 0 0 8   A R

The continued advances to the WCDMA cellular air interface standards are being made under a 
program  within  3GPP  entitled  “Long Term  Evolution”  (LTE). There  is  a  similar  long  term 
evolution program underway within 3GPP2 for cdma2000 (referred to as UMB). Both of these 
evolution  programs  are  based  on  OFDM/OFDMA  technology.  LTE  standards  are  nearing 
completion, with final specifications expected in mid-2009. Virtually all current mobile operators 
have  indicated  their  intention  to  upgrade  their  networks  to  LTE  when  it  is  available. This 
selection has had substantial negative impact on the proposed 3GPP2 UMB standard, which no 
mobile operators have indicated an intention to use. 3GPP has also initiated preliminary work 
on  a  follow-on  to  LTE,  called  LTE-Advanced  (LTE-A),  which  is  intended  to  be  the  3GPP  entry 
into  the  worldwide  ITU-R  “IMT-Advanced”  project,  a  follow-on  to  the  earlier  IMT-2000 
Recommendation mentioned above.

IEEE 802-Based Standards

The  wireless  Standard,  IEEE  802.11,  was  first  ratified  in  1997.  Since  that  time,  the  IEEE  802.11 
Working Group has continued to update and expand the basic IEEE 802.11 Standard to achieve 
higher  data  rates,  accommodate  additional  operating  frequencies  and  provide  additional 
features. Equipment conforming to these Standards (i.e., IEEE 802.11a/b/g) is in the marketplace 
today.  Intended  primarily  for  short  range  applications,  operating  in  unlicensed  frequency  
bands  and  requiring  minimal  infrastructure,  IEEE  802.11  Standards-based  equipment  has  
seen substantial market growth, especially in consumer home networking applications. Similar 
to  3G,  this  Standard  also  continues  to  evolve  toward  higher  data  rates  and  improved  
service capabilities.

The  wide  area  network  community  has  also  established  the  IEEE  802.16 Working  Group  to 
define  air  interface  Standards  for  longer  distance  (2  to  50  km)  Metropolitan Area  and Wide  
Area  Networks  (MAN/WAN). The  first  802.16  Standard  was  published  in  2002.  Specifying 
operating  frequencies  from  10  to  66  GHz,  it  is  primarily  aimed  toward  very  high  speed  wide 
area  point  to  multipoint  fixed  applications.  In  2003,  an  amendment  to  the  802.16  Standard 
(802.16a)  was  published  which  added  operation  in  the  2  to  11  GHz  frequency  bands. This 
addition made the Standard much more suitable for providing wireless broadband high-speed 
Internet access for residential and small office applications. In 2004, 802.16a and several other 
amendments  to  the  base  802.16  Standard  were  combined  into  a  single  document  which  was 
published as 802.16-2004 and which was ultimately adopted by the WiMAX Business Forum for 
fixed use deployments. Equipment conforming to the 802.16-2004 fixed Standard was initially 
introduced  in  2006.  Concurrent  with  this  revision  of  the  fixed  Standard,  the  802.16 Working 
Group  embarked  on  defining  a  mobile  version  of  the  Standard  (referred  to  as  802.16e). The 
mobile  version  of  the  Standard  was  completed  and  published  in  February  2006  and  initial 
equipment certification by the WiMAX Forum commenced in late 2007.

The WiMAX  Forum  adopted  a  specific  form  of  the  802.16e  Standard  for  development  and 
deployment  as “mobile WiMAX.” The  802.16e  mobile  standard  is  being  further  developed  as 
802.16m  to  improve  its  performance  and  capabilities.  802.16m  is  specifically  targeted  to  meet 

I N T E R D I G I TA L  2 0 0 8   A R   5

the  ITU-R  requirements  for  “IMT-Advanced,”  the  follow-on  to  the  earlier  ITU-R  IMT-2000 
Recommendation  mentioned  above.  It  is  anticipated  that  the WiMAX  Forum  will  also  adopt 
802.16m when it is completed in 2010.

More  recently,  the  IEEE  802  community  has  begun  to  address  the  question  of  handover 
between  the  different  IEEE  802  technologies,  both  wired  and  wireline,  as  well  as  handover  to 
external non-802 networks, such as cellular. This group, IEEE 802.21, entitled Media Independent 
Handover  Services,  has  completed  their  initial  Standard,  and  it  was  approved  by  the  IEEE  in 
2008. The  IEEE  802.21  technology  is  specifically  oriented  towards  the  future  all-IP  Next 
Generation Network that merges existing fixed and mobile networks into a single homogeneous 
integrated  network  capable  of  supporting  all  envisioned  advanced  fixed  and  mobile  services 
including voice, data and video.

InterDigital’s Strategy

A  core  component  of  our  strategy  is  the  ability  to  develop  advanced  digital  wireless 
technologies. We  will  continue  to  develop  those  technologies,  contribute  our  ideas  to  the 
Standards  bodies  and  bring  those  technologies  to  market,  generating  revenues  from  patent 
licensing as well as sales of our technology solutions. Our goal is to derive revenue from every 
3G  mobile  device  sold,  either  in  the  form  of  patent  licensing  revenues,  technology  solutions-
related  revenues  or  a  combination  of  these  elements.  In  recent  years,  our  patent  license 
agreements  have  contributed  the  majority  of  our  cash  flow  and  revenues. As  of  December 
2008, we had entered into patent license agreements covering approximately one-half of all 3G 
mobile devices sold worldwide. In addition, our technology solutions offer an additional means 
to generate revenue from 3G mobile devices. However, we are currently evaluating a number 
of  options  for  the  modem  portion  of  our  business. These  options  include  an  acquisition  or 
partnership to achieve the appropriate scale needed to succeed in the market or the disposition 
of the modem portion of our business through a sale or closure.

Our strategy for achieving our goal is as follows:

•  Continue to fund significant technology development;

•  Maintain substantial involvement in key worldwide Standards bodies, contributing to 
the ongoing definition of wireless Standards and incorporating our inventions into 
those Standards;

•  License our patented technology to wireless equipment producers worldwide, maximizing 

realizable value in our 3G licenses by investing the time necessary to negotiate appropriate 
economic terms for 3G products;

•  Defend vigorously our intellectual property and related contractual rights;

•  Offer technology solutions to both semiconductor producers and mobile device 
manufacturers, pending our evaluation of the modem portion of our business;

•  Examine opportunities to acquire related or complementary technologies and capabilities;

•  Depending on the result of our evaluation of the modem portion of our business, we might 
continue to offer technology and/or product solutions to both semiconductor producers and 
mobile device manufacturers.

InterDigital’s Technology Position

Cellular Technologies

We  have  a  long  history  of  developing  cellular  technologies  including  those  related  to  CDMA 
and TDMA technologies, and more recently, OFDMA and MIMO technologies. A number of our 
TDMA-based  and  CDMA-based  inventions  are  being  used  in  all  2G,  2.5G  and  3G  wireless 
networks and mobile terminal devices.

We led the industry in establishing TDMA-based TIA/EIA-54 as a digital wireless U.S. Standard 
in  the  1980s. We  developed  a  substantial  portfolio  of TDMA-based  patented  inventions. These 
inventions  include  or  relate  to  fundamental  elements  of TDMA-based  systems  in  use  around 
the world. Some of our TDMA inventions include or relate to:

•  The fundamental architecture of commercial Time Division/Frequency Division Multiple Access 
(TD/FDMA) systems

•   Methods of synchronizing TD/FDMA systems

•  A  flexible  approach  to  managing  system  capacity  through  the  reassignment  of  online 
subscriber units to different time slots and/or frequencies in response to system conditions

•  The design of a multi-component base station, utilizing distributed intelligence, which allows 
for more robust performance

•  Initializing procedures that enable roaming

We also have developed and patented innovative CDMA technology solutions. Today, we hold 
a  significant  worldwide  portfolio  of  CDMA  patents  and  patent  applications.  Similar  to  our 
TDMA  inventions,  we  believe  that  a  number  of  our  CDMA  inventions  are  essential  to  the 
implementation  of  CDMA  systems  in  use  today.  Some  of  our  CDMA  inventions  include  or 
relate to:

•  Global  pilot: The  use  of  a  common  pilot  channel  to  synchronize  sub-channels  in  a  multiple 

access environment

•  Bandwidth allocation: Techniques including multi-channel and multi-code mechanisms

•  Power  control:  Highly  efficient  schemes  for  controlling  the  transmission  output  power  of 

terminal and base station devices, a vital feature in a CDMA system

•  Joint detection and interference cancellation techniques for reducing interference

•  Soft handover enhancement techniques between designated cells

•  Various sub-channel access and coding techniques

•  Packet data

•  Fast handoff

•  Geo-location for calculating the position of terminal users

•  Multi-user detection (MUD)

•  High speed packet data channel coding

•  High speed packet data delivery in a mobile environment, including enhanced uplink

The  cellular  industry  has  ongoing  initiatives  aimed  at  technology  improvements. We  have 
engineering  development  projects  to  build  and  enhance  our  technology  portfolio  in  many  of 
these areas, including the Long Term Evolution (LTE) project for 3GPP radio technology, further 
evolution  of  the  3GPP WCDMA  Standard  (including  HSPA+),  and  continuing  improvements  to 
the  legacy  GSM-EDGE  Radio Access  Network  (GERAN). The  common  goal  is  to  improve  the 

I N T E R D I G I TA L  2 0 0 8   A R   7

user experience and reduce the cost to operators via increased capacity, reduced cost per bit, 
increased data rates and reduced latency. Of the above technologies, LTE is the most advanced 
in that it uses the newer OFDMA/MIMO technologies.

IEEE 802-based Wireless Technologies

Our  strong  wireless  background  includes  engineering  and  corporate  development  activities 
that focus on solutions that apply to other wireless market segments. These segments primarily 
fall within the continually expanding scope of the IEEE 802 family of Standards. We are building 
a  portfolio  of  technology  related  to  the WLAN, WMAN  and  digital  cellular  area  that  includes,  
for example, improvements to the IEEE 802.11 PHY and MAC to increase peak data rates (i.e., 
IEEE 802.11n), handover among radio access technologies (IEEE 802.21), mesh networks (IEEE 
802.11s),  radio  resource  measurements  (IEEE  802.11k),  wireless  network  management  (IEEE 
802.11v),  wireless  network  security  and  broadband  wireless  (IEEE  802.16,  including WiMAX 
wireless technology).

Business Activities

Patent Licensing

Our Patent Portfolio

As  of  December  31,  2008,  our  patent  portfolio  consisted  of  1,058  U.S.  patents  (136  of  which 
issued  in  2008),  and  3,792  non-U.S.  patents  (571  of  which  issued  in  2008). We  also  have 
numerous  patent  applications  pending  worldwide. As  of  December  31,  2008  we  had  1,212 
pending  applications  in  the  U.S.  and  7,782  pending  non-U.S.  patent  applications. The  patents 
and  applications  comprising  our  portfolio  relate  specifically  to  digital  wireless  radiotelephony 
technology  (including,  without  limitation, TDMA  and/or  CDMA)  and  expire  at  differing  times 
ranging from 2008 through 2028.

The  United  States  Patent  and Trademark  Office  (USPTO)  permits  the  filing  of “provisional” 
applications for, among other reasons, preserving rights to an invention prior to filing a formal 
“non-provisional”  application. Typically,  the  filing  of  a  provisional  application  is  followed  with 
the  filing  of  a “non-provisional”  application,  which  may  add  content,  such  as  claim  language, 
to  the  provisional  application,  or  may  combine  multiple  provisional  applications. The  USPTO, 
along  with  other  international  patent  offices,  also  permits  the  filing  of  “continuation”  or 
“divisional”  applications,  which  are  based,  in  whole  or  in  part,  on  a  previously  filed  non-
provisional  patent  application.  Most  of  our  foreign  patent  applications  are  single  treaty 
application  filings,  which  can  lead  to  patents  in  all  of  the  countries  that  are  parties  to  a 
particular treaty. During 2008, we filed 608 U.S. patent applications consisting of 192 first filed, 
U.S.  non-provisional,  non-continuation  patent  applications,  312  U.S.  provisional  applications 
and 104 U.S. continuation, continuation-in-part, divisional, reissue or reexamination applications 
and  US  applications  claiming  priority  from  PCT  or  other  non-US  applications. Typically,  each 
new  U.S.  non-provisional  application  is  used  as  the  basis  for  the  later  filing  of  one  or  more 
foreign applications.

Patent Licenses

Currently, numerous manufacturers supply digital cellular equipment conforming to 2G and 3G 
Standards. We  believe  that  any  of  those  companies  that  use  our  patented  inventions  will 
require  licenses  from  us. While  some  companies  seek  licenses  before  they  commence 
manufacturing  and/or  selling  devices  that  use  our  patented  inventions,  most  do  not. 
Consequently,  we  approach  companies  and  seek  to  establish  license  agreements. We  expend 
significant  effort  identifying  potential  users  of  our  inventions  and  negotiating  patent  license 
agreements with companies that may be reluctant to take licenses. We are in active discussions 

8       I N T E R D I G I TA L  2 0 0 8   A R

with  a  number  of  companies  regarding  the  licensing  of  our  2G  and  3G-related  patents  on  a 
worldwide  basis.  During  negotiations,  unlicensed  companies  may  raise  varying  defenses  and 
arguments as to their need to enter into a patent license with us, to which we respond. In the 
past  year,  these  defenses  and  arguments  have  included  positions  by  companies:  (i)  as  to  the 
essential  nature  of  our  patents,  (ii)  that  our  royalty  rates  are  not  fair,  reasonable  or 
nondiscriminatory,  (iii)  that  their  products  do  not  infringe  our  patents  and/or  that  our  patents 
are  invalid  and/or  unenforceable,  and  (iv)  concerning  the  impact  of  litigation  between  us  and 
other third parties. If we believe that a third party is required to take a license to our patents in 
order  to  manufacture  and  sell  products,  we  might  commence  legal  action  against  the  third 
party if they refuse to enter into a patent license agreement.

We offer non-exclusive, royalty-bearing patent licenses to companies that manufacture, import, 
use  or  sell,  or  intend  to  manufacture,  import,  use  or  sell,  equipment  that  implements  the 
inventions covered by our portfolio of patents. We have entered into numerous non-exclusive, 
non-transferable  (with  limited  exceptions)  patent  license  agreements  with  companies  around 
the world. When we enter into a new patent license agreement, the licensee typically agrees to 
pay consideration for sales made prior to the effective date of the license agreement and also 
agrees to pay royalties or license fees on covered products that it will sell or anticipates selling 
during the  term  of the agreement. We expect that, for the most part, new license agreements 
will follow this model. Our patent license agreements are structured on a royalty-bearing basis, 
paid-up  basis  or  combination  thereof.  Most  of  our  patent  license  agreements  are  royalty 
bearing. Most of these agreements provide for the payment of royalties on an ongoing basis, 
based on sales of covered products built to a particular Standard (convenience based licenses). 
Others provide for the payment of royalties on an ongoing basis if the manufacture, sale or use 
of the licensed product infringes one of our patents (infringement based licenses).

Our  license  agreements  typically  contain  provisions  which  give  us  the  right  to  audit  our 
licensees’ books and records to ensure compliance with the licensees’ reporting and payment 
obligations under those agreements. From time to time, these audits reveal underreporting or 
underpayments  under  the  applicable  agreements.  In  such  cases,  we  might  enter  into 
negotiations  or  dispute  resolution  proceedings  with  the  licensee  to  resolve  the  discrepancy, 
either of which might lead to payment of all or a portion of the amount claimed due under the 
audit or termination of the license.

We recognize the revenue from per-unit royalties in the period when we receive royalty reports 
from  licensees.  In  circumstances  where  we  receive  consideration  for  sales  made  prior  to  the 
effective date of a patent license, we may recognize such payments as revenue in the quarter 
in  which  the  patent  license  agreement  is  signed.  Some  of  these  patent  license  agreements 
provide  for  the  non-refundable  prepayment  of  royalties  which  are  usually  made  in  exchange 
for prepayment  discounts. As the licensee reports sales of covered products, the royalties are 
calculated and either applied against any prepayment, or become payable in cash. Additionally, 
royalties on sales of covered products under the license agreement become payable or applied 
against  prepayments  based  on  the  royalty  formula  applicable  to  the  particular  license 
agreement. These formulas include flat dollar rates per-unit, a percentage of sales, percentage 
of  sales  with  a  per-unit  cap  and  other  similar  measures. The  formulas  can  also  vary  by  other 
factors including territory, covered Standards, quantity and dates sold.

Some  of  our  patent  licenses  are  paid-up,  requiring  no  additional  payments  relating  to 
designated sales under agreed upon conditions. Those conditions can include paid-up licenses 
for a period of time, for a class of products, under certain patents or patent claims, for sales in 
certain  countries  or  a  combination  thereof.  Licenses  have  become  paid-up  based  on  the 
payment of fixed amounts or after the payment of royalties for a term. We recognize revenues 
related to fixed amounts on a straight-line basis.

I N T E R D I G I TA L  2 0 0 8   A R   9

Some of our patent licenses contain “most favored licensee” (“MFL”) clauses, which permit the 
licensee to elect to apply the terms of a subsequently executed license agreement with another 
party that are more favorable than those of the licensee’s original agreement. The application of 
the  MFL  clause  may  affect,  and  generally  acts  to  reduce,  the  amount  of  royalties  payable  by 
the licensee. The application of an MFL clause can be complex, given the varying terms among 
patent license agreements.

In  addition  to  patent  licensing,  we  actively  seek  to  license  know-how  both  to  companies  
with  whom  we  have  had  strategic  relationships  (including  alliance  partners)  and  to  
other companies.

The achievement of our long term strategic objectives is based on securing 3G patent license 
agreements  with  a  substantial  portion,  if  not  all,  of  the  mobile  phone  industry.  Because  the 
vast  majority  of  3G  mobile  device  sales  are  expected  to  occur  in  the  future,  we  believe  the 
Company  is  best  served  by  entering  into  patent  license  agreements  on  appropriate  economic 
terms,  even  if  securing  such  terms  results  in  completing  the  negotiation  of  any  particular 
license later than it otherwise could have been completed on less favorable terms.

2008 Patent License Activity

In second quarter 2008, we entered into a worldwide, non-transferable, non-exclusive, royalty-
bearing  convenience-based  patent  license  agreement  with ASUSTeK  Computer  Inc.,  covering 
the sale of terminal units and infrastructure compliant with 2G, 2.5G, and 3G Standards.

In second quarter 2008, we entered into a worldwide, non-transferable, non-exclusive, royalty-
bearing convenience-based patent license agreement with Pegatron Corp. covering the sale of 
terminal units and infrastructure compliant with 2G, 2.5G, and 3G Standards.

In fourth quarter 2008, we entered into non-exclusive, worldwide, royalty-bearing, convenience-
based, patent license agreement with ModeLabs Group covering the sale of terminal units and 
infrastructure compliant with 2G, 2.5G, 3G, and IEE 802-based Standards.

In fourth quarter 2008, we entered into non-exclusive, worldwide, royalty-bearing, convenience-
based, patent license agreement with iWOW Connections Pte Ltd covering the sale of terminal 
units and infrastructure compliant with 2G, 2.5G, and 3G Standards.

In fourth quarter 2008, we entered into a binding term sheet with Samsung Electronics Co., Ltd. 
(“Samsung”)  and  its  affiliates  that  resolved  the  outstanding  arbitration  issues  involving 
Samsung’s sale of 2G products, as well as the 3G patent licensing disputes for Samsung’s sales 
of products  through 2012.  Under the terms of the term sheet,  we  agreed  to grant Samsung a 
paid-up non-exclusive, worldwide, fixed fee royalty-bearing license covering the sale of single 
mode  terminal  units  and  infrastructure  compliant  with TDMA-based  2G  Standards  that  is  to 
become  paid-up  in  2010  and  a  non-exclusive,  worldwide,  fixed  fee  royalty-bearing  license 
covering  the  sale  of  terminal  units  and  infrastructure  compliant  with  3G  Standards  through 
2012. The agreement also ended the payment disputes regarding Samsung’s royalty obligations 
for sales of 2G products. Under the terms of the term sheet, Samsung was able to elect one of 
two  defined  payment  options.  Subject  to  Samsung’s  selection  of  a  payment  option  and 
payment  of  the  first  installment  of  payments  due,  the  parties  agreed  to  move  to  end  all 
litigations  and  arbitration  proceedings  ongoing  between  them.  Pursuant  to  the  term  sheet,  in 
first quarter 2009, we entered into the 2009 Samsung Agreement with Samsung, incorporating 
the terms of the term sheet.

Patent Licensees Generating 2008 Revenues Exceeding 10% of Total Revenues

In  2008,  LG  Electronics,  Inc.  (“LG”),  Sharp  Corporation  of  Japan  (“Sharp”)  and  NEC 
Corporation of Japan (“NEC”) comprised approximately 25%, 16% and 12% of our total 2008 
revenues, respectively.

10       I N T E R D I G I TA L  2 0 0 8   A R

We are party to a worldwide, non-exclusive, royalty-bearing, convenience-based patent license 
agreement  with  LG  covering  the  sale  of  (i)  terminal  units  compliant  with  2G  and  2.5G TDMA-
based  and  3G  Standards,  and  (ii)  infrastructure  compliant  with  cdma2000  technology  and  its 
extensions up to a limited threshold amount. Under the terms of the patent license agreement, 
LG  paid  us  $95.0  million  in  each  of  the  first  quarters  of  2006,  2007,  and  2008. The  agreement 
expires  at  the  end  of  2010  upon  which  LG  will  receive  a  paid-up  license  to  sell  single-mode 
GSM/GPRS/EDGE  terminal  units  under  the  patents  included  under  the  license,  and  become 
unlicensed as to all other products covered under the agreement. We are recognizing revenue 
associated  with  this  agreement  on  a  straight-line  basis  from  the  inception  of  the  agreement 
until December 31, 2010.

ITC  is  a  party  to  a  worldwide,  non-exclusive,  generally  nontransferable,  royalty-bearing, 
convenience-based patent license agreement with Sharp (Sharp PHS/PDC Agreement) covering 
sales  of  terminal  devices  compliant  with TDMA-based  PHS  and  PDC  Standards.  In  fourth 
quarter 2006, ITC and Sharp entered into an Amendment which extended the term of the Sharp 
PHS/PDC Agreement from April 2008 to April 2011. Sharp is obligated to make royalty payments 
on  sales  of  licensed  products  as  covered  products  are  sold. We  recognize  revenue  associated 
with this agreement in the periods we receive the related royalty reports.

ITC  and  Sharp  are  also  parties  to  a  separate  worldwide,  non-exclusive,  convenience-based, 
generally  nontransferable,  royalty-bearing  patent  license  agreement  (Sharp  NCDMA/GSM/3G 
Agreement) covering sales of GSM, narrowband CDMA and 3G products that expires upon the 
last to expire of the patents licensed under the agreement. Sharp is obligated to make royalty 
payments  on  sales  of  licensed  products,  to  the  extent  it  does  not  have  a  royalty  credit,  as 
covered  products  are  sold.  As  part  of  the  2006  Amendment  referred  to  in  the  preceding 
paragraph, Sharp made additional lump-sum payments and agreed to prepay estimated 2007 
royalties  on  designated  sales. We  recognized  revenue  associated  with  this  agreement  in  the 
periods  that  the  royalty  reports  were  received. This  license  agreement  expires  upon  the  last  
to  expire  of  the  patents  licensed  under  this  agreement.  In  2008,  we  recorded  revenues  of  
$36.7  million  from  Sharp  of  which  approximately  $36.2  million  is  attributable  to  the  Sharp 
NCDMA/GSM/3G Agreement and the balance is attributable to the Sharp PHS/PDC Agreement.

ITC  is  a  party  to  a  worldwide,  non-exclusive,  generally  nontransferable,  royalty-bearing, 
narrowband  CDMA  and  3G  patent  license  agreement  with  NEC.  Pursuant  to  its  patent  license 
agreement  with  ITC,  NEC  is  obligated  to  pay  royalties  on  a  convenience  basis  on  all  sales  of 
products  covered  under  the  license. We  recognize  revenue  associated  with  this  agreement  in 
the  periods  we  receive  the  related  royalty  reports.  NEC  and  ITC  are  also  parties  to  a  separate 
non-exclusive,  worldwide,  convenience-based,  generally  nontransferable,  royalty-bearing 
TDMA  patent  license  agreement  (2G).  It  is  unlikely  that  NEC  would  have  any  further  royalty 
payment  obligations  under  that  agreement  based  on  existing  paid-up  and  other  unique 
provisions. In 2008, we recorded revenues of $26.6 million from NEC, all of which is attributable 
to our narrowband CDMA and 3G patent license agreement.

Subsequent Event

On  January  14,  2009,  we  entered  into  the  2009  Samsung  Agreement  with  Samsung, 
superseding  the  binding  term  sheet  signed  in  November  2008  by  such  parties. The  2009 
Samsung Agreement  terminated  the  1996  Samsung Agreement.  Under  the  terms  of  the  2009 
Samsung Agreement,  we  granted  Samsung  a  non-exclusive,  worldwide,  fixed  fee  royalty-
bearing  license  covering  the  sale  of  single  mode  terminal  units  and  infrastructure  compliant 
with TDMA-based  2G  Standards  that  is  to  become  paid-up  in  2010  and  a  non-exclusive, 
worldwide, fixed fee royalty-bearing license covering the sale of terminal units and infrastructure 
compliant  with  3G  Standards  through  2012.  Pursuant  to  the  payment  option  selected  by 
Samsung,  Samsung  has  agreed  to  pay  InterDigital  $400.0  million  in  four  equal  installments 

I N T E R D I G I TA L  2 0 0 8   A R   11

over an 18-month period. Samsung paid its first $100.0 million installment in first quarter 2009. 
Under the terms of the 2009 Samsung Agreement, the parties moved to end all litigation and 
arbitration proceedings ongoing between them.

Patent Oppositions

In  high  technology  fields  characterized  by  rapid  change  and  engineering  distinctions,  the 
validity  and  value  of  patents  are  sometimes  subject  to  complex  legal  and  factual  challenges 
and  other  uncertainties. Accordingly,  our  patents  are  subject  to  uncertainties  typical  of  patent 
enforcement generally. Third parties have challenged and continue to challenge the validity of 
some  of  our  patents  in  various  jurisdictions. The  cost  of  enforcing  and  protecting  our  patent 
portfolio is significant.

Patent Infringement and Declaratory Judgment Proceedings

From  time  to  time,  if  we  believe  any  party  is  required  to  license  our  patents  in  order  to 
manufacture and sell certain digital cellular products and such party has not done so, we may 
institute  legal  action  against  them. This  legal  action  typically  takes  the  form  of  a  patent 
infringement lawsuit or an administrative proceeding such as a Section 337 proceeding before 
the U.S. International Trade Commission (“USITC”). In a patent infringement lawsuit, we would 
typically seek damages for past infringement and an injunction against future infringement. In 
a USITC proceeding, we would typically seek an exclusion order to bar infringing goods from 
entry into the United States, as well as a cease and desist order to bar further sales of infringing 
goods that have already been imported into the United States. The response from the subject 
party  can  come  in  the  form  of  challenges  to  the  validity,  enforceability,  essentiality  and/or 
applicability  of  our  patents  to  their  products.  In  addition,  a  party  might  file  a  Declaratory 
Judgment  action  to  seek  a  court’s  declaration  that  our  patents  are  invalid,  unenforceable,  not 
infringed by the other party’s product, or are not essential. Our response to such a Declaratory 
Judgment action may include claims of infringement. When we include claims of infringement 
in a patent infringement lawsuit, a favorable ruling for the Company can result in the payment 
of damages for past sales, the setting of a royalty for future sales or issuance by the court of an 
injunction enjoining the manufacturer from manufacturing and/or selling the infringing product. 
As part of a settlement of a patent infringement lawsuit against a third party, we could typically 
seek to recover consideration for past infringement, and grant a license under the patent(s) in 
suit  (as  well  as  other  patents)  for  future  sales.  Such  a  license  could  take  any  of  the  forms 
discussed above.

Contractual Arbitration Proceedings

We  and  our  licensees,  in  the  normal  course  of  business,  may  have  disagreements  as  to  the 
rights and obligations of the parties under the applicable license agreement. For example, we 
could  have  a  disagreement  with  a  licensee  as  to  the  amount  of  reported  sales  and  royalties. 
Our  license  agreements  typically  provide  for  audit  rights  as  well  as  private  arbitration  as  the 
mechanism for resolving disputes. Arbitration proceedings can be resolved through an award 
rendered by the arbitrators or by settlement between the parties. Parties to an arbitration might 
have the right to have the Award reviewed in a court of competent jurisdiction. However, based 
on public policy favoring the use of arbitration, it is difficult to have arbitration awards vacated 
or  modified. The  party  securing  an  arbitration  award  may  seek  to  have  that  award  converted 
into  a  judgment  through  an  enforcement  proceeding. The  purpose  of  such  a  proceeding  is  to 
secure a judgment that can be used for, if need be, seizing assets of the other party.

Technology Solutions Development

We have designed, developed and placed into operation a variety of advanced digital wireless 
technologies, systems and products since our inception in the early 1970s. Over the course of 
our history, our strength has been our ability to explore emerging technologies, identify needs 
created  by  the  development  of  advanced  wireless  systems  and  build  technologies  for  those 
new requirements.

Today,  we  are  focusing  our  technology  solutions  development  efforts  on  advanced  cellular 
technologies. This  includes  developing  3G WCDMA  technologies,  including  HSDPA/HSUPA 
implementations,  and  the  3GPP  LTE  technology.  Our  SlimChip  family  of  mobile  broadband 
modem  solutions  integrates  2G  GSM/GPRS/EDGE  solutions,  which  we  have  licensed  from 
Infineon  with  our  advanced  3G  technology  (WCDMA/HSDPA/HSUPA).  Our  SlimChip  mobile 
broadband  modem  solutions  consist  of  SlimChip  IP  (broadband  modem  intellectual  property 
know-how),  SlimChip  ICs  (high  performance  baseband  ICs),  SlimChip  Reference  Platforms 
(chipsets, software, and reference designs) and SlimChip embedded modules.

We  also  develop  advanced  IEEE  802  wireless  technologies,  in  particular  technology  related  to 
WLAN and digital cellular applications that include data rate and latency improvements to IEEE 
802.11,  handover  among  radio  access  technologies  (IEEE  802.21)  and  wireless  network 
management  and  security.  For  example,  we  have  developed  a  mobility  solution  based  on 
802.21  that  greatly  improves  handover  performance  between WiBro  (a  Korean  version  of 
mobile WiMAX) and UMTS networks.

We  recorded  expenses  of  $101.3  million,  $87.1  million  and  $65.4  million  during  2008,  2007,  
and  2006,  respectively,  related  to  our  research  and  development  efforts. These  efforts  
foster inventions which are the basis for many of our patents. As a result of such patents and 
related  patent  license  agreements,  in  2008,  2007  and  2006,  we  recognized  $216.5  million, 
$230.8 million and $473.6 million of patent licensing revenue, respectively. In addition, in 2008, 
2007,  and  2006,  we  recognized  technology  solutions  revenues  totaling  $12.0  million,  
$3.4 million and $6.9 million, respectively.

3G WCDMA/HSDPA/HSUPA Technology and Product Solutions Development

We have developed for sale or license our own SlimChip family of mobile broadband solutions, 
which  supports  digital  cellular  functionality  for  2G  and  3G,  including  HSDPA  and  HSUPA.  In 
addition, we continue to support other customers in developing their 3G offerings.

The  InterDigital  SlimChip  family  of  products  supports  functionality  compliant  with  R6  HSDPA 
and HSUPA technologies. The family of SlimChip products includes:

SlimChip High Performance Baseband ICs

•  Slim modem architecture optimized for mobile broadband devices

•  Advanced  receiver  technology  and  receive  diversity  for  superior  cell-edge  performance  and 

interference mitigation

•  Power-efficient design using advanced battery saving techniques

SlimChip Reference Platforms

•  Complete  chipsets,  software  and  reference  designs  for  mobile  broadband  devices,  such  as 

ExpressCards, USB sticks and mini cards for notebooks and UMPCs

•  Production tools for calibration, debug, software upgrades

I N T E R D I G I TA L  2 0 0 8   A R   13

SlimChip Modem IP that is proven in silicon

 •  2G and 3G physical layers

 •  Dual mode protocol stack with InterRAT

 •  Optimized integration of GSM/GPRS/EDGE/WCDMA/HSDPA/HSUPA

Our SlimChip technology solutions feature a “slim” modem architecture where the modem — 
which provides core wireless connectivity — is separated from the applications processor and 
peripheral  functions. This  approach  allows  terminal  unit  manufacturers  to  customize  the 
modem,  in  a  rapid  and  cost-efficient  manner,  to  specific  mobile  broadband  devices  such  as 
data cards, smart phones or feature phones.

SlimChip  technology  solutions  feature  advanced  receiver  technology  with  receive  diversity, 
providing superior interference mitigation resulting in higher data speeds and better coverage. 
In  pre-customer  trials,  the  SlimChip  Reference  Platform  in  an  Express  Card  form  factor  has 
delivered  true  mobile  broadband  performance  with  data  speeds  of  up  to  7.2  Mbps  in  the 
downlink  and  1.5  Mbps  in  the  uplink. The  SlimChip  design  supports  speeds  up  to  10  Mbps  in 
the downlink and 5.7 Mbps in the uplink.

The  Company  continues  to  conduct  interoperability  testing  against  various  2G/3G  network 
vendor’s  equipment,  pre-certification  efforts  of  its  SlimChip  modem  chipset  and  reference 
platform,  including  ETSI  conformance  tests  for  GCF  (Global  Certification  Forum)  certification 
testing and continues to conduct additional customer evaluations and testing. In October 2008, 
we  announced  that,  due  to  the  rapidly  changing  landscape  of  suppliers  and  customers  of 
digital baseband technology, we were evaluating a number of options for the modem portion 
of  our  business. These  options  could  include  an  acquisition  or  partnership  to  achieve  the 
appropriate  scale  needed  to  succeed  in  the  market,  or  the  disposition  of  the  modem  product 
portion of our business through a sale or closure. We continue to evaluate these options, and 
while we have had substantive discussions with potential counterparties, we have not made a 
final determination of the most appropriate option to pursue.

Continuing Technology and Standards Development

Recognizing  the  need  continually  to  improve  data  rates,  coverage  and  capacity,  work  is 
currently  underway  within  3GPP  on  further  evolution  of  the WCDMA  Standards,  including 
evolution of HSPA (HSDPA/HSUPA) to downlink data rates of 20-40 Mbps and uplink data rates 
of approximately 10 Mbps. Releases 7 and 8 are expected to address incremental performance 
improvements to WCDMA and HSPA (HSDPA/HSUPA) including the incorporation of MIMO and 
other data throughput and latency improvements and power saving features.

In addition, work continues on a longer term initiative, Evolved UTRA/UTRAN (UMTS Terrestrial 
Radio Access/UMTS Terrestrial  Radio Access  Network),  also  known  at  Long Term  Evolution  or 
LTE. The objectives of this initiative are more ambitious, targeting peak data rates of 300 Mbps 
in the downlink and 75 Mbps in the uplink, improved spectrum efficiency, significantly reduced 
data  latency,  and  scalable  bandwidths  from  as  low  as  1.25  MHz  to  as  high  as  20  MHz. 
We  are  actively  participating  in  the  HSDPA/HSUPA  and  LTE  Standards  activities  and  have 
launched  internal  projects  to  develop  the  technology  necessary  to  support  the  new 
performance requirements.

Wireless LAN, Mobility and Security

As  part  of  our  broader  technology  development  activities,  we  are  developing  solutions 
addressing WLAN  technology  and  mobility  between WLAN  and  cellular  networks. These 
projects  support  activities  within  the  IEEE  802,  ITU  and  3GPP  network  architecture  working 
groups. Technology  development  areas  include  improvements  to  the  802.11  PHY  and  MAC  

14       I N T E R D I G I TA L  2 0 0 8   A R

to  increase  peak  data  rates  (i.e.,  IEEE  802.11n),  handover  between  radio  access  technologies 
(i.e.,  IEEE  802.21),  mesh  networks,  wireless  network  management,  and  wireless  network  and 
device security.

3G WCDMA Technology Solutions Customers and Partners

Infineon Technologies AG

We  jointly  developed  and  continue  to  support  a  3G  protocol  stack  for  use  in  terminal  units 
under  our  2001  cooperative  development,  sales  and  alliance  agreement  with  Infineon 
Technologies AG  (Infineon). This  3G  protocol  stack  interfaces  with  existing  GSM/GPRS/EDGE 
protocol  stack  software  to  provide  dual-mode  (2G/3G)  protocol  stack  functionality,  supports 
Infineon’s 3G baseband processor, and is portable to other baseband processors. Together with 
Infineon, we completed the full dual-mode WCDMA/FDD release 99 protocol stack in 2003. This 
protocol  stack  solution  has  been  commercially  deployed  and  continues  to  be  offered  to  3G 
mobile  phone  and  semiconductor  producers. The  technology  is  operating  on  commercial 
networks  around  the  world. We  have  supported  Infineon  with  interoperability  testing  and 
continue  to  support  product  launch  and  certification  with  field  support,  software  support  and 
lab testing. In fourth quarter 2005, we extended our 3G protocol stack relationship with Infineon 
to  include  the  joint  development  and  commercialization  of  upgraded,  Standards-compliant 
Release  5  protocol  stacks  with  HSDPA  functionality.  In  the  first  quarter  of  2006,  we  further 
extended  our  3G  protocol  stack  relationship  with  Infineon  to  include  joint  development  and 
commercialization  of  an  upgraded,  Standards-compliant  Release  6  protocol  stack  to  include 
HSUPA functionality.

Also  in  fourth  quarter  2005,  we  entered  into  a  new  agreement  with  Infineon  permitting  us 
independently to offer a complete dual-mode GSM/GPRS/EDGE and WCDMA/HSDPA integrated 
protocol  stack  to  the  market.  Under  the  agreement,  we  have  licensed  Infineon’s  legacy  GCF-
certified  GSM/GPRS/EDGE  protocol  stack,  which  we  are  now  able  to  license  to  customers  in 
combination  with  our  evolving  3G  protocol  stack  and  baseband  offering. This  provides  us  the 
ability  to  offer  a  comprehensive  Standards-compliant WCDMA  Release  5  dual-mode  protocol 
stack,  as  well  as  a  complete  3G  physical  to  application  layer  modem  solution.  In  addition  to 
GCF certification, the GSM/GPRS/EGDE protocol stack has 75 type approvals and has completed 
interoperability testing with more than 80 operators in 40 countries worldwide.

In fourth quarter 2006, we announced an additional expansion of our relationship with Infineon, 
whereby  we  have  licensed  Infineon’s  field-proven  GSM/GPRS/EDGE  baseband  modem,  the 
S-GOLD(R) 3, and have also licensed the layer one control software (in addition to the protocol 
stack software which had previously been licensed). This provides us with the ability to offer a 
comprehensive Standards-compliant 2G/3G modem solution. Under the terms of the extended 
agreement  with  Infineon,  we  have  the  right  to  use  the  Infineon  2G  technology  in  our  own 
modem  offering  or  to  sublicense  the  technology  to  third  parties  developing  their  own  2G/3G 
modem  offerings. We  also  gain  access  to  all  of  the  applicable  design  specifications,  source 
code and other design data for Infineon’s integrated GSM/GPRS/EDGE baseband and protocol 
stack technology, including the S-GOLD(R) 3 baseband processor ASIC design with support for 
Infineon’s RF, Power Management and Connectivity modules as well as related components.

General Dynamics C4 Systems

In December 2004, we entered into an agreement with General Dynamics C4 Systems (formerly 
known  as  General  Dynamics  Decision  Systems,  Inc.)  (General  Dynamics)  to  serve  as  a 
subcontractor  on  the  Mobile  User  Objective  System  (MUOS)  program  for  the  U.S.  military. 
MUOS  is  an  advanced  tactical  terrestrial  and  satellite  communications  system  utilizing  3G 
commercial  cellular  technology  to  provide  significantly  improved  high  data  rate  and  assured 
communications for U.S. war fighters.

I N T E R D I G I TA L  2 0 0 8   A R   15

Under  the  Software  License Agreement  (SLA),  we  delivered  to  General  Dynamics  Standards-
compliant WCDMA  modem  technology,  originating  from  the  technology  we  developed  under 
our  original  agreement  with  Infineon,  for  incorporation  into  handheld  terminals. The  SLA 
provided for the payment of $18.5 million in exchange for delivery of, and a limited license to, 
our  commercial  technology  solution  for  use  within  the  U.S.  Government’s  MUOS  and  Joint 
Tactical Radio System programs. Maintenance and product training were also covered by this 
amount. A majority of our MUOS program deliverables and related payments occurred during 
2005. We completed delivery of our technology solution in 2006. In addition to the deliverables 
specifically  identified  in  the  SLA,  we  originally  agreed  to  provide  software  maintenance 
services  for  a  period  of  three  years  and  additional  future  services  as  requested  by  General 
Dynamics.  In  fourth  quarter  2006,  General  Dynamics  agreed  to  amend  the  SLA  to  release  
us  from  our  maintenance  obligations  over  the  final  two  years  of  the  SLA,  in  exchange  for  a 
$0.5  million  reduction  to  their  remaining  payments  and  provision  of  limited  engineering 
support services. We recognized approximately $0.9 million in fourth quarter 2006 as a result of 
this amendment.

NXP Semiconductors B.V. (formerly Philips Semiconductors)

In August  2005,  we  entered  into  an  agreement  with  NXP  (formerly  Philips  Semiconductors 
B.V.)  to  deliver  our  physical  layer  HSDPA  technology  solution  to  NXP  for  integration  into  its 
family  of  Nexperia™  cellular  system  chipsets.  Under  the  agreement,  we  will  also  agree  to 
assist  NXP  with  chip  design  and  development,  software  modification  and  system  integration 
and testing to implement our HSDPA technology solution into the NXP chipset. Subsequent to 
our delivery of portions of our HSDPA technology solution, we agreed to provide NXP support 
and maintenance over an aggregate estimated period of approximately two years.

SK Telecom

As part of our technology development, from time to time we develop technology solutions for 
customers  that  are  complementary  to  our  existing  development  programs.  For  example,  in 
December  2006  we  announced  that  SK Telecom,  Korea’s  leading  mobile  communications 
Company,  had  chosen  InterDigital  to  develop  an  advanced  mobility  solution  for  nationwide 
session  continuity. The  mobility  solution,  based  on  IEEE  802.21  Standards,  will  support 
nationwide  handover  for  SK Telecom’s  customers  when  moving  between WiBro  (a  Korean 
version of mobile WiMAX) and UMTS networks throughout the country. InterDigital’s solution, 
based  on  the  IEEE  802.21  Standard  for  Media  Independent  Handoff,  includes  both  the  system 
design and the software solution for dual mode WiBro/UMTS terminal units.

In  January  of  2008,  the  Company  and  SK Telecom  extended  the  collaboration  to  develop 
additional mobile wireless handover capability adding features to enhance a seamless mobility 
between different radio technologies including WiBro, UMTS and cmda2000.

All of the above programs have provided validation of the technology and access to third party 
facilities and resources, and helped to broaden the awareness of the Company as a developer 
of advance wireless inventions.

Other Customers

In  January  2008,  the  Company  licensed  its  SlimChip  solutions  to  a  leading  Asian  fabless 
semiconductor  company  for  integration  into  the  licensee’s  dual-mode  ICs.  Under  the 
licensing agreement, we provided a complete UMTS 3GPP Release 6 modem technology and 
customer support.

In June 2008, a mobile broadband module company selected the SlimChip IC modem solution 
for  integration  in  the  customer’s  leading  USB  modems  and  advance  wireless  modules  that 
enable high-speed mobile broadband connectivity in laptops and other portable devices.

16       I N T E R D I G I TA L  2 0 0 8   A R

The Company is also in active dialog and testing with several potential customers for both its 
SlimChip modem IP, and its SlimChip baseband IC solutions.

Future Technology Partnerships and Acquisitions

In  addition  to  our  internal  research  and  development  programs,  we  pursue  a  number  of 
channels  to  investigate,  develop  and  acquire  new  architectures  and  technologies  for  wireless 
systems. These  efforts  include  advanced  air  interface  technologies  and  new  technologies  that 
may  support  new  network  architectures  and  interoperability  techniques  such  as  collaborative 
communications,  cognitive  radio  and  seamless  connectivity.  For  example,  national  and 
international university relationships have provided us additional opportunities to explore new 
technologies and license intellectual property advancements that we sponsored.

We  maintain  an  active  corporate  development  program  that  seeks  further  investment 
opportunities  in  technologies  that  can  enhance  the  attractiveness  and  profitability  of  our 
technology solutions. We have also engaged in selective acquisitions to enhance our intellectual 
property portfolio and/or accelerate our time-to-market.

Competition

Our  patent  portfolio  is  unique. We  do  not  compete  in  a  traditional  sense  with  other  patent 
holders  because  other  patent  holders  do  not  have  the  same  rights  to  the  inventions  and 
technologies  encompassed  by  our  patent  portfolio.  However,  when  licensing  our  patent 
portfolio,  we  compete  with  other  patent  holders  for  a  share  of  royalties  that  face  practical 
limitations. We believe that licenses under a number of our patents are required to manufacture 
and  sell  2G  and  3G  products.  However,  numerous  companies  also  claim  that  they  hold 
essential 2G and 3G patents. To the extent that multiple parties all seek royalties on the same 
product, the manufacturers may claim to have difficulty in meeting the financial requirements 
of  each  patent  holder.  In  the  past,  certain  manufacturers  have  sought  antitrust  exemptions  to 
act  collectively  on  a  voluntary  basis.  In  addition,  certain  manufacturers  have  sought  to  limit 
aggregate 3G licensing fees or rates for essential patents.

We compete in a wireless communications market characterized by rapid technological change, 
frequent  product  introductions,  evolving  industry  Standards  and,  in  many  products,  price 
erosion.  Further,  many  current  and  potential  competitors  may  have  advantages  over  us, 
including  (i)  existing  royalty-free  cross-licenses  to  competing  and  emerging  technologies;  (ii) 
longer  operating  histories  and  presence  in  key  markets;  (iii)  greater  name  recognition;  (iv) 
access to larger customer bases; (v) economies of scale and cost structure advantages; and (vi) 
greater  financial,  sales  and  marketing,  manufacturing,  distribution,  technical  and  other 
resources. The communications industry continues to be dominated by entities with substantial 
market  share. That  share  advantage  provides  pricing  advantages,  brand  strength  and 
technological influence. In addition, the combination of the market dynamics described above 
is driving many industry participants to consolidate. This consolidation may affect the timing or 
ability  of  third  parties  to  purchase  products  or  license  technology  from  us. We  also  face 
competition  from  the  in-house  development  teams  at  the  semiconductor  and  wireless  device 
manufacturing  companies  that  may  be  developing  technology  that  is  competitive  with  our 
offering. In addition, new competitors may enter the market. Some manufacturers that develop 
the  technology  for  their  own  products  may  choose  to  license  that  technology  to  other 
manufacturers. In addition, as a greater proportion of wireless 3G cellular devices incorporate 
traditional computing applications and IEEE wireless technologies (e.g., 802.11, 802.15, 802.16), 
semiconductor  companies  that  have  traditionally  focused  on  providing  chipsets  to  these 
industries may enter the 3G cellular market with baseband solutions as well.

Employees

As  of  December  31,  2008,  we  employed  379  employees.  None  of  our  employees  are 
represented by a collective bargaining unit. In addition, we have contracted other companies to 
provide  us  with  additional  engineering  resources. As  of  December  31,  2008,  these  companies 
provided us with approximately 121 full time equivalents.

Geographic Concentrations

During 2008, 2007 and 2006, revenue from domestic customers was $10.9 million, $6.7 million 
and  $3.8  million,  respectively,  representing  5%,  3%  and  1%  of  our  total  revenues  of  $228.5 
million,  $234.2  million,  and  $480.5  million,  respectively.  During  these  periods, Asian-based 
customers comprised 84%, 80% and 39% of total revenues, respectively, and European-based 
customers comprised 3%, 11% and 59% of total revenues, respectively.

At  December  31,  2008  and  2007,  we  held  $143.9  million,  or  98%,  and  $130.2  million  or  97%, 
respectively, of our property and equipment, patents and other intangible assets in the United 
States of America, net of accumulated depreciation and amortization. We also held $2.6 million 
and  $4.3  million,  respectively,  of  property  and  equipment,  net  of  accumulated  depreciation, 
in Canada.

We face a variety of risks that might affect our business, financial condition, operating results 
or any combination thereof. Although many of the risks discussed below are driven by factors 
that  we  cannot  control  or  predict,  you  should  carefully  consider  the  identified  risks  before 
making an investment decision with respect to our common stock. In addition to the risks and 
uncertainties identified elsewhere in this Annual Report as well as other information contained 
herein, each of the following risk factors should be considered in evaluating our business and 
prospects. If any of the following risks or uncertainties occur or develop, our business, results 
of  operations  and  financial  condition  could  change.  In  such  an  event,  the  market  price  of  our 
common  stock  could  decline  and  you  could  lose  all  or  part  of  your  investment. The  following 
discussion  addresses  those  risks  that  management  believes  are  the  most  significant  and  that 
might  affect  our  business,  financial  condition  or  operating  results,  although  there  are  other 
risks that could arise or might become more significant than anticipated.

Risks Relating to Our Revenues and Cash Flow

Challenges Relating to Our Ability to Enter into New License Agreements Could Cause Our 
Revenues and Cash Flow to Decline.

We  face  challenges  in  entering  into  new  patent  license  agreements.  During  discussions  with 
unlicensed  companies,  significant  negotiation  issues  arise  from  time  to  time.  For  example, 
manufacturers and sellers of 2G products could be reluctant to enter into a license agreement 
because such companies might be required to make a significant payments for unlicensed past 
sales. Moreover, a significant part of our TDMA patent portfolio expired in 2006. Also, certain of 
the  inventions  we  believe  will  be  employed  in  3G  products  and  other  future  technologies  are 
the  subject  of  our  patent  applications  where  no  patent  has  been  issued  yet  by  the  relevant 
patent reviewing authorities. Certain prospective licensees are unwilling to license patent rights 
prior to a patent’s issuance. Additionally, in the ordinary course of negotiations, in response to 
our  demand  that  they  enter  into  a  license  agreement,  manufacturers  raise  different  defenses 
and arguments including, but not limited to, (i) claims by third parties challenging the essential 
nature  of  our  patents,  (ii)  claims  that  their  products  do  not  infringe  our  patents  or  that  our 
patents are invalid or unenforceable, (iii) certain patents should be excluded from the license, 

18       I N T E R D I G I TA L  2 0 0 8   A R

(iv) our royalty rates are not fair, reasonable or nondiscriminatory, and (v) the potential impact 
that  any  litigation  or  arbitration  in  which  we  are  involved  might  have  on  such  manufacturers. 
We cannot assure that all prospective licensees will be persuaded during negotiations to enter 
into a patent license agreement with us, either at all or on terms acceptable to us.

In addition, our financial condition and operating results could continue to fluctuate because (i) 
a  significant  portion  of  our  licensing  revenues  are  currently  dependent  on  sales  by  our 
licensees  that  are  outside  our  control  and  that  could  be  negatively  affected  by  a  variety  of 
factors,  including  global  and/or  country-specific  economic  conditions,  buying  patterns  of  end 
users, competition for our licensees’ products and any decline in the sale prices our licensees 
receive  for  their  covered  products;  (ii)  the  strength  of  our  patent  portfolio  could  be  weakened 
through patents being declared invalid, our claims being narrowed, changes to the Standards 
and patent laws and regulations and adverse court or arbitration decisions; (iii) it is difficult to 
predict the timing and amount of licensing revenue associated with past infringement and new 
licenses, and the timing, nature or amount of revenues associated with strategic partnerships; 
(iv) we might not be able to enter into additional or expanded strategic partnerships, either at 
all or on acceptable terms; and (v) our markets are subject to increased competition from other 
products  and  technologies.  In  addition,  our  operating  results  also  could  be  affected  by  (i) 
general economic and other conditions that cause a downturn in the market for the customers 
of our products or technologies or (ii) increased expenses that could result from factors such as 
increased  litigation  and  arbitration  costs,  actions  designed  to  keep  pace  with  technology  and 
product market targets or strategic investments. Further, due to the fact that our expenses are 
relatively  fixed,  variations  in  revenue  from  a  small  number  of  customers  could  cause  our 
operating  results  to  vary  from  quarter  to  quarter.  Our  revenue  and  cash  flow  also  could  be 
affected by (i) the unwillingness of any licensee to satisfy all of their royalty obligations on the 
terms or within the timeframe we expect or a decline in the financial condition of any licensee 
or  (ii)  the  failure  of  2G/2.5G  and  3G  sales  to  meet  market  forecasts  due  to  global  economic 
conditions, political instability, competitive technologies or otherwise. The foregoing factors are 
difficult to forecast and could adversely affect both our quarterly and annual operating results 
and financial condition.

Challenges Relating to Our Existing License Agreements Could Cause Our Revenue and 
Cash Flow to Decline.

Revenue  and  cash  flow  from  existing  and  potential  licensees  might  be  affected  by  challenges 
to our interpretation of provisions of license agreements. Such challenges or difficulties could 
result  in  rejection  or  modification  of  license  agreements  or  the  termination,  reduction  and 
suspension of payments.

The  licenses  granted  to  and  from  us  under  a  number  of  our  license  agreements  include  only 
patents  that  are  either  filed  or  issued  prior  to  a  certain  date,  and,  in  a  small  number  of 
agreements,  royalties  are  payable  on  those  patents  for  a  specified  time  period. As  a  result, 
there  are  agreements  with  some  licensees  where  later  patents  are  not  licensed  by  or  to  us 
under our license agreements. In order to license these later patents, we will need to extend or 
modify  our  license  agreements  or  enter  into  new  license  agreements  with  the  licensees. We 
might not be able to modify the license agreements in the future to license any later patents or 
extend  the  date(s)  to  incorporate  later  patents  without  affecting  the  material  terms  and 
conditions of our license agreements with such licensees.

I N T E R D I G I TA L  2 0 0 8   A R   19

Some  of  our  license  agreements  have  fixed  terms. We  will  need  to  renegotiate  license 
agreements  with  fixed  terms  prior  to  the  expiration  of  the  license  agreements  and,  based  on 
various factors, including the technology and business needs and competitive positions of our 
licensees,  we  might  not  be  able  to  renegotiate  the  license  agreements  on  similar  terms,  or  at 
all. In order to maintain existing relationships with some of our licensees, we might be forced 
to  renegotiate  license  agreements  on  terms  that  are  more  favorable  to  the  licensees,  which 
could  harm  our  results  of  operations.  If  we  fail  to  renegotiate  our  license  agreements,  we 
would lose existing licensees and our business would be materially adversely affected.

Our licenses could contain provisions that would cause the licensee’s obligation to pay royalties 
to be reduced or suspended for an indefinite period, with or without the accrual of the royalty 
obligation.  For  example,  existing  license  agreements  could  be  renegotiated  or  restructured 
based on MFL or other provisions contained in the applicable license agreement. The assertion 
or validity of any such provisions under existing agreements could affect our cash flow and/or 
the timing and amount of future recurring licensing revenue.

Setbacks in Defending and Enforcing Our Patent Rights Could Cause Our Revenue and Cash 
Flow to Decline.

Major  telecommunications  equipment  manufacturers  have  challenged,  and  we  expect  will 
continue to challenge, the validity and infringement of our patents. In some instances, certain 
of  our  patent  claims  have  been  declared  invalid  or  substantially  narrowed. We  cannot  assure 
that  the  validity  of  our  patents  will  be  maintained  or  that  any  of  the  key  patents  will  be 
determined  to  be  applicable  to  any  particular  product. Any  significant  adverse  finding  as  to 
the  validity  or  scope  of  our  key  patents  could  result  in  the  loss  of  patent  licensing 
revenue from existing licensees and could substantially impair our ability to secure new patent 
licensing arrangements.

For  example,  we  are  engaged  in  a  proceeding  against  Nokia  in  the  USITC  alleging  that  Nokia 
engaged in an unfair trade practice by selling for importation into the United States, importing 
into  the  United  States  and  selling  after  importation  into  the  United  States  certain  3G  mobile 
handsets  and  components  that  infringe  four  of  InterDigital’s  patents.  If  we  are  delayed  or 
unsuccessful in this matter, we might be delayed in collecting, collect less than we expect or be 
unable  to  collect  royalties  from  Nokia  on  its  sales  of  3G  products. Any  significant  adverse 
outcome  in  the  Nokia  litigation  could  also  substantially  impair  our  ability  to  renew  existing 
license agreements or secure new licensing arrangements with other parties.

Royalty Rates Could Decrease for Future License Agreements.

Certain  licensees  and  others  in  the  wireless  industry,  individually  and  collectively,  are 
demanding that royalty rates for 2G and 3G patents be lower than historic royalty rates and, in 
some cases, that the aggregate royalty rates for 2G and 3G products be capped. A number of 
companies  have  made  claims  as  to  the  essential  nature  of  their  patents  with  respect  to 
products  for  the  3G  market.  Both  the  increasing  number  of  patent  holders  of  3G  and  future 
technologies and the efforts, if successful, by certain industry members and groups to reduce 
and/or place caps on royalty rates for 2G, 3G and future technologies could result in a decrease 
in  the  royalty  rates  we  receive  for  use  of  our  patented  inventions,  thereby  decreasing  future 
anticipated revenue and cash flow.

Our Revenues Are Derived Primarily from a Limited Number of Patent Licensees.

We  earn  a  significant  amount  of  our  revenues  from  a  limited  number  of  licensees,  and  we 
expect that a significant portion of our revenues will continue to come from a limited number 
of licensees for the foreseeable future. In the event one or more of these licensees fail to meet 

20       I N T E R D I G I TA L  2 0 0 8   A R

their payment or reporting obligations under their respective license agreements, we lose any 
of  these  licensees  or  our  revenues  from  these  licensees  decline,  our  future  revenue  and  cash 
flow could be materially adversely affected.

It Is Difficult for Us to Verify Royalty Amounts Owed to Us Under Our Licensing Agreements, 
and This Might Cause Us to Lose Revenues.

The  standard  terms  of  our  license  agreements  require  our  licensees  to  document  the 
manufacture and sale of products that incorporate our technology and report this data to us on 
a  quarterly  basis. Although  our  standard  license  terms  give  us  the  right  to  audit  books  and 
records  of  our  licensees  to  verify  this  information,  audits  can  be  expensive,  time  consuming, 
flawed and potentially detrimental to our ongoing business relationship with our licensees. Our 
license  compliance  program  randomly  audits  licensees  to  independently  verify  the  accuracy  
of  the  information  contained  in  their  royalty  reports  in  an  effort  to  decrease  the  likelihood  
that  we  will  not  receive  the  royalty  revenues  to  which  we  are  entitled  under  the  terms  of  our 
license agreements, but we cannot give assurances that the random audits will be effective to 
that end.

Risks Relating to Our Expenses

Due to the Nature of Our Business, We Could Be Involved in a Number of Litigation, 
Arbitration and Administrative Proceedings.

While  some  companies  seek  licenses  before  they  commence  manufacturing  and/or  selling 
devices that use our patented inventions, most do not. Consequently, we approach companies 
and seek to establish license agreements for using our inventions. We expend significant effort 
identifying  potential  users  of  our  inventions  and  negotiating  license  agreements  with 
companies that might be reluctant to take licenses. However, if we believe that a third party is 
required  to  take  a  license  to  our  patents  in  order  to  manufacture,  sell  or  use  products,  we 
might  commence  legal  or  administrative  action  against  the  third  party  if  they  refuse  to  enter 
into  a  license  agreement.  In  turn,  we  could  face  counterclaims  that  challenge  the  essential 
nature  of  our  patents,  that  our  patents  are  invalid,  unenforceable  or  not  infringed  or  that  our 
royalty rates are not fair, reasonable or nondiscriminatory. As a result of enforcing our IPR, we 
could  be  subject  to  significant  legal  fees  and  costs,  including  the  costs  and  fees  of  opposing 
counsel  in  certain  jurisdictions  if  we  are  unsuccessful.  In  addition,  litigation,  arbitration  and 
administrative  proceedings  require  significant  key  employee  involvement  for  significant 
periods of time, which could divert these employees from other business activities.

In addition, the cost of defending our intellectual property has been and might continue to be 
significant. Litigation might be required to enforce our intellectual property rights, protect our 
trade  secrets,  enforce  patent  license  and  confidentiality  agreements  or  determine  the  validity 
and  scope  of  proprietary  rights  of  others.  In  addition,  third  parties  could  commence  litigation 
against  us  seeking  to  invalidate  our  patents  or  to  have  determined  that  our  patents  are  not 
infringed, or are not essential or invalid or unenforceable. As a result of any such litigation, we 
could  lose  our  proprietary  rights  or  incur  substantial  unexpected  operating  costs. Any  action 
we take to protect our intellectual property rights could be costly and could require significant 
amounts of time by key members of executive management and other personnel that, in turn, 
could  negatively  affect  our  results  of  operations.  Moreover,  third  parties  could  circumvent 
certain of our patents through design changes. Any of these events could adversely affect our 
prospects for realizing future revenue.

I N T E R D I G I TA L  2 0 0 8   A R   21

Any Disposition of Our Modem Business Could Result in Charges or Expenditures.

Due  to  the  rapidly  changing  landscape  of  digital  baseband  technology,  we  are  evaluating  a 
number of options for the modem portion of our business, which could include the disposition 
of our modem business through a sale or closure. Any disposition could result in an impairment 
of assets related to the modem business and could also result in a repositioning charge and a 
significant reduction to our technology solutions revenue.

We Might Face Claims by Third Parties that We Infringe Their Intellectual Property.

A  number  of  third  parties  publicly  have  claimed  that  they  own  patents  essential  to  various 
wireless  Standards.  Certain  of  our  technology  solutions  are  designed  to  comply  with  these 
Standards.  If  any  of  our  technology  solutions  are  found  to  infringe  the  intellectual  property 
rights of a third party, we could be required to redesign the technology solutions, take a license 
from the third party, pay damages to the third party or indemnify a customer or supplier for its 
damages  or  other  losses.  If  we  are  not  able  to  negotiate  a  license  and/or  if  we  cannot 
economically  redesign  the  technology  solutions,  we  could  be  prohibited  from  marketing  the 
technology solutions. In this case, our prospects for realizing future revenue could be adversely 
affected.  If  we  are  required  to  obtain  licenses  and/or  pay  royalties  to  one  or  more  patent 
holders,  this  could  have  an  adverse  effect  on  the  commercial  implementation  of  our  wireless 
technology  solutions.  In  addition,  the  associated  costs  to  defend  such  claims  could  be 
significant and could divert the attention of key executive management and other personnel.

Risks Related to Our Business Strategy, Markets and Competition

The Outcome of Potential Domestic Patent Legislation, USPTO Rule Changes, International 
Patent Rule Changes and Third Party Legal Proceedings Might Affect Our Patent Prosecution, 
Licensing and Enforcement Strategies.

Changes  to  certain  U.S.  patent  laws  and  regulations  might  occur  in  the  future,  some  or  all  of 
which  might  affect  our  patent  costs,  the  scope  of  future  patent  coverage  we  secure  and 
remedies  we  might  be  awarded  in  patent  litigation,  and  might  require  us  to  reevaluate  and 
modify our patent prosecution, licensing and enforcement strategies. As in prior years, the U.S. 
Congress  might  consider  modification  of  select  patent  laws  relating  to,  among  other  things, 
how  patent  damages  are  calculated  and  the  procedures  for  challenging  issued  patents  and 
where  patent  lawsuits  can  be  filed  in  the  United  States. Additionally,  there  have  been  recent 
U.S.  Supreme  Court  and  other  court  rulings  relating  to,  among  other  things,  the  standard  for 
determining whether an invention is obvious, which is a key issue when assessing patentability 
of  new  inventions  and  validity  of  issued  patents,  the  ability  of  a  patent  holder  to  obtain 
injunctive  relief  against  infringers  and  the  ability  of  patent  licensees  to  challenge  the  patents 
under which they are licensed. The ruling concerning injunctions might make it more difficult, 
under  some  circumstances,  for  us  to  obtain  injunctive  relief  against  a  party  that  has  been 
found  to  infringe  one  or  more  of  our  patents,  and  the  ruling  regarding  patent  challenges  by 
licensees  could  potentially  make  it  easier  for  our  licensees  to  challenge  our  patents  even 
though they have already agreed to take a license. In addition, the potential effect of rulings in 
legal  proceedings  among  third  parties  might  affect  our  licensing  program. We  continue  to 
monitor  and  evaluate  our  prosecution,  licensing  and  enforcement  strategies  with  regard  to 
these proposals and changes.

We Depend on Key Senior Management, Engineering and Licensing Resources.

Our  future  success  depends  largely  upon  the  continued  service  of  our  directors,  executive 
officers and other key management and technical personnel. Our success also depends on our 
ability to continue to attract, retain and motivate qualified personnel with specialized licensing, 
engineering and other skills. The market for such specialized talent in our industry is extremely 

22       I N T E R D I G I TA L  2 0 0 8   A R

competitive. In particular, competition exists for qualified individuals with expertise in licensing 
and  with  significant  engineering  experience  in  cellular  and  air  interface  technologies  such  as 
WCDMA. Our ability to attract and retain qualified personnel could be affected by any adverse 
decisions in any litigation or arbitration and by our ability to offer competitive cash and equity 
compensation and work environment conditions. The failure to attract and retain such persons 
with  relevant  and  appropriate  experience  could  interfere  with  our  ability  to  enter  into  new 
license  agreements  and  undertake  additional  technology  and  product  development  efforts,  as 
well as our ability to meet our strategic objectives.

We Might Engage in Acquisitions or Strategic Transactions or Make Investments that  
Could Result in Significant Changes or Management Disruption and Fail to Enhance 
Shareholder Value.

We  continue  to  evaluate  and  might  acquire  businesses,  enter  into  joint  ventures  or  other 
strategic  transactions  and  purchase  equity  and  debt  securities,  including  minority  interests  in 
publicly-traded and private companies and corporate bonds/notes. Most strategic investments 
entail a high degree of risk and will not become liquid until more than one year from the date 
of  investment,  if  at  all.  Acquisitions  or  strategic  investments  might  not  generate  financial 
returns or result in increased adoption or continued use of our technologies. In addition, other 
investments  might  not  generate  financial  returns  or  might  result  in  losses  due  to  market 
volatility, the general level of interest rates and inflation expectations. We could make strategic 
investments  in  early-stage  companies,  which  require  us  to  consolidate  or  record  our  share  of 
the  earnings  or  losses  of  those  companies.  Our  share  of  any  such  losses  would  adversely 
affect our financial results until we exit from or reduce our exposure to these investments.

Achieving the anticipated benefits of acquisitions depends in part upon our ability to integrate 
the acquired businesses in an efficient and effective manner. The integration of companies that 
have  previously  operated  independently  might  result  in  significant  challenges,  and  we  might 
be unable to accomplish the integration smoothly or successfully. The difficulties of integrating 
companies include, among others:

• retaining key employees;

• maintenance of important relationships;

• minimizing the diversion of management’s attention from ongoing business matters;

• coordinating geographically separate organizations;

• consolidating research and development operations; and

• consolidating corporate and administrative infrastructures.

We cannot assure you that the integration of acquired businesses with our business will result 
in the realization of the full benefits anticipated by us to result from the acquisition. We might 
not  derive  any  commercial  value  from  the  acquired  technology,  products  and  intellectual 
property  or  from  future  technologies  and  products  based  on  the  acquired  technology  and/or 
intellectual  property,  and  we  might  be  subject  to  liabilities  that  are  not  covered  by 
indemnification protection we might obtain.

Our Industry Is Subject to Rapid Technological Change, Uncertainty and Shifting  
Market Opportunities.

Our  market  success  depends,  in  part,  on  our  ability  to  define  and  keep  pace  with  changes  in 
industry Standards, technological developments and varying customer requirements. Changes 
in  industry  Standards  and  needs  could  adversely  affect  the  development  of,  and  demand  for, 
our  technology,  rendering  our  technology  currently  under  development  obsolete  and 
unmarketable. The  patents  and  applications  comprising  our  portfolio  have  fixed  terms  and,  if 

I N T E R D I G I TA L  2 0 0 8   A R   23

we  fail  to  anticipate  or  respond  adequately  to  these  changes  through  the  development  or 
acquisition of new patentable inventions, patents or other technology, we could miss a critical 
market opportunity, reducing or eliminating our ability to capitalize on our patents, technology 
solutions or both.

Our Technologies Might Not Be Adopted By the Market or Widely Deployed.  

We  invest  significant  engineering  resources  in  the  development  of  advanced  wireless 
technology  and  related  solutions. These  investments  might  not  be  recoverable  or  might  not 
result in meaningful revenue if products based on the technologies in which we invest are not 
widely  deployed.  Competing  digital  wireless  technologies  could  reduce  the  opportunities  for 
deployment of technologies we develop. If the technologies in which we invest are not adopted 
in the mainstream markets or in time periods we expect, or if we are unable to secure partner 
support  for  our  technologies,  our  business,  financial  condition  and  operating  results  could  be 
adversely affected.

The Markets for Our Technology Solutions Might Fail to Materialize in the Manner We Expect.

We are positioning our current development projects for the evolving advanced digital wireless 
markets. Certain of these markets might continue to develop at a slower rate or pace than we 
expect  and  might  be  of  a  smaller  size  than  we  expect.  In  addition,  there  could  be  fewer 
applications  for  our  technology  and  products  than  we  expect. The  development  of  advanced 
wireless  markets  also  could  be  affected  by  general  economic  conditions,  customer  buying 
patterns,  timeliness  of  equipment  development,  pricing  of  advanced  wireless  infrastructure 
and  mobile  devices,  rate  of  growth  in  telecommunications  services  and  the  availability  of 
capital  for,  and  the  high  cost  of,  radio  frequency  licenses  and  infrastructure  improvements. 
Failure of the markets for our technologies and/or our products to materialize to the extent or 
at  the  rate  we  expect  could  reduce  our  opportunities  for  sales  and  licensing  and  could 
materially adversely affect our long-term business, financial condition and operating results.

Market Projections and Data are Forward-Looking in Nature.

Our  strategy  is  based  on  our  own  projections  and  on  analyst,  industry  observer  and  expert 
projections,  which  are  forward-looking  in  nature  and  are  inherently  subject  to  risks  and 
uncertainties. The  validity  of  their  and  our  assumptions,  the  timing  and  scope  of  the  3G  and 
future  markets,  economic  conditions,  customer  buying  patterns,  timeliness  of  equipment 
development, pricing of products, growth in wireless telecommunications services that would 
be  delivered  on  3G  devices  and  availability  of  capital  for  infrastructure  improvements  could 
affect  these  predictions. The  inaccuracy  of  any  of  these  projections  could  adversely  affect  our 
operating results and financial condition. In addition, market data upon which we rely is based 
on third party reports that might be inaccurate.

We Face Substantial Competition from Companies with Greater Resources.

Competition in the wireless telecommunications industry is intense. We face competition from 
companies  developing  other  and  similar  technologies,  including  existing  companies  with 
in-house  development  teams  and  new  competitors  to  the  market.  Many  current  and  potential 
competitors might have advantages over us, including: (i) existing royalty-free cross-licenses to 
competing  and  emerging  technologies;  (ii)  longer  operating  histories  and  presence  in  key 
markets; (iii) greater name recognition; (iv) access to larger customer bases; (v) economies of 
scale  and  cost  structure  advantages;  and  (vi)  greater  financial,  sales  and  marketing, 
manufacturing,  distribution,  technical  and  other  resources.  In  particular,  our  more  limited 
resources and capabilities might adversely affect our competitive position if the market were to 
move  toward  the  provision  of  an  existing  complete  technology  platform  solution  that  larger 
equipment manufacturers have the ability to provide.

24       I N T E R D I G I TA L  2 0 0 8   A R

Our Technology and Product Development Activities Might Experience Delays.

We might experience technical, financial, resource or other difficulties or delays related to the 
further  development  of  our  technologies  and  products.  Delays  might  have  adverse  financial 
effects  and  might  allow  competitors  with  comparable  technology  and/or  product  offerings  to 
gain a commercial advantage over us. There can be no assurance that we will continue to have 
adequate staffing or that our development efforts will ultimately be successful. Moreover, our 
technologies  have  not  been  fully  tested  in  commercial  use,  and  it  is  possible  that  they  might 
not  perform  as  expected.  In  addition,  we  might  experience  adverse  effects  due  to  potential 
delays  or  denials  in  obtaining  export  licenses  for  the  transfer  of  certain  of  our  technologies, 
which  might  be  deemed  controlled  technology  under  U.S.  export  control  laws,  to  certain 
countries.  In  such  cases,  our  business,  financial  condition  and  operating  results  could  be 
adversely  affected  and  our  ability  to  secure  new  customers  and  other  business  opportunities 
could be diminished.

We Rely on Relationships with Third Parties to Develop and Deploy Technology Solutions.

Successful exploitation of our technology solutions is partially dependent on the establishment 
and success of relationships with equipment producers and other industry participants. Delays 
or  failure  to  enter  into  licensing  or  other  relationships  to  facilitate  technology  development 
efforts or delays or failure to enter into technology licensing agreements to secure integration 
of additional functionality could impair our ability to introduce into the market portions of our 
technology  and  resulting  products,  cause  us  to  miss  critical  market  windows  or  impair  our 
ability to remain competitive.

Other Risks

Currency Fluctuations Could Negatively Affect Future Product Sales or Royalty Revenues or 
Increase the U.S. Dollar Cost of Our Activities and International Strategic Investments.

We  are  exposed  to  risk  from  fluctuations  in  currencies,  which  might  change  over  time  as  our 
business  practices  evolve,  that  could  impact  our  operating  results,  liquidity  and  financial 
condition. We  operate  and  invest  globally. Adverse  movements  in  currency  exchange  rates 
might negatively affect our business due to a number of situations, including the following:

•  If  the  effective  price  of  products  sold  by  our  customers  were  to  increase  as  a  result  of 
fluctuations  in  the  exchange  rate  of  the  relevant  currencies,  demand  for  the  products  could 
fall, which in turn would reduce our royalty revenues.

•  Assets or liabilities of our consolidated subsidiaries might be subject to the effects of currency 
fluctuations,  which  might  affect  our  reported  earnings.  Our  exposure  to  foreign  currencies 
might increase as we expand into new markets.

•  Certain  of  our  revenues,  such  as  royalty  revenues,  are  derived  from  licensee  or  customer 
sales that are denominated in foreign currencies. If these revenues are not subject to foreign 
exchange  hedging  transactions,  weakening  of  currency  values  in  selected  regions  could 
adversely affect our near term revenues and cash flows. In addition, continued weakening of 
currency  values  in  selected  regions  over  an  extended  period  of  time  could  adversely  affect 
our future revenues and cash flows.

•  Certain of our operating and investing costs, such as foreign patent prosecution, are based in 
foreign  currencies.  If  these  costs  are  not  subject  to  foreign  exchange  hedging  transactions, 
strengthening  currency  values  in  selected  regions  could  adversely  affect  our  near  term 
operating expenses, investment costs and cash flows. In addition, continued strengthening of 
currency  values  in  selected  regions  over  an  extended  period  of  time  could  adversely  affect 
our future operating expenses, investment costs and cash flows.

I N T E R D I G I TA L  2 0 0 8   A R   25

•  We could, in the future, engage in foreign exchange hedging transactions that could affect our 
cash  flows  and  earnings  because  they  might  require  the  payment  of  structuring  fees,  and 
they might limit the U.S. dollar value of royalties from licensees’ sales that are denominated 
in foreign currencies.

We Face Risks from Doing Business in Global Markets.

A significant portion of our business opportunities exist in a number of international markets. 
Accordingly,  we  could  be  subject  to  the  effects  of  a  variety  of  uncontrollable  and  changing 
factors,  including:  difficulty  in  protecting  our  intellectual  property  in  foreign  jurisdictions; 
enforcing  contractual  commitments  in  foreign  jurisdictions  or  against  foreign  corporations; 
government regulations, tariffs and other applicable trade barriers; currency control regulations 
and  variability  in  the  value  of  the  U.S.  dollar  against  foreign  currency;  social,  economic  and 
political instability; natural disasters, acts of terrorism, widespread illness and war; potentially 
adverse tax consequences; and general delays in remittance of and difficulties collecting non-
U.S.  payments.  In  addition,  we  also  are  subject  to  risks  specific  to  the  individual  countries  in 
which we, our customers and our licensees do business.

Changes to Our Current Calculation of Tax Liabilities Could Have an Adverse Effect on Our 
Consolidated Financial Condition or Results of Operations.

The  calculation  of  tax  liabilities  involves  significant  judgment  in  estimating  the  impact  of 
uncertainties  in  the  application  of  complex  tax  laws. We  are  subject  to  examinations  by  the 
Internal Revenue Service (IRS) and other taxing jurisdictions on various tax matters, including 
challenges to various positions we assert in our filings and foreign tax liability and withholding. 
With  our  January  1,  2007  adoption  of  FIN  48,  certain  tax  contingencies  are  recognized  when 
they  are  determined  to  be  more  likely  than  not  to  occur.  Although  we  believe  we  have 
adequately accrued for tax contingencies that meet this criterion, we might be required to pay 
taxes  in  excess  of  the  amounts  we  have  accrued. As  of  December  31,  2008  and  2007,  there 
were certain tax contingencies that did not meet the applicable criteria to record an accrual. In 
the  event  that  the  IRS  or  another  taxing  jurisdiction  levies  an  assessment  in  the  future,  it  is 
possible the assessment could have an adverse effect on our consolidated financial condition 
or results of operations.

The High Amount of Capital Required to Obtain Radio Frequency Licenses, Deploy and 
Expand Wireless Networks and Obtain New Subscribers Could Slow the Growth of the 
Wireless Communications Industry and Adversely Affect Our Business.

Our  growth  is  dependent  upon  the  increased  use  of  wireless  communications  services  that 
utilize our technology. In order to provide wireless communications services, wireless operators 
must obtain rights to use specific radio frequencies. The allocation of frequencies is regulated 
in the United States and other countries throughout the world, and limited spectrum space is 
allocated  to  wireless  communications  services.  Industry  growth  might  be  affected  by  the 
amount of capital required to obtain licenses to use new frequencies, deploy wireless networks 
to offer voice and data services, expand wireless networks to grow voice and data services and 
obtain  new  subscribers. The  significant  cost  of  licenses,  wireless  networks  and  subscriber 
additions  might  slow  the  growth  of  the  industry  if  wireless  operators  are  unable  to  obtain  or 
service  the  additional  capital  necessary  to  implement  or  expand  advanced  wireless  networks. 
Our growth could be adversely affected if this occurs.

26       I N T E R D I G I TA L  2 0 0 8   A R

Consolidation in the Wireless Communications Industry Could Adversely Affect  
Our Business.

The wireless communications industry has experienced consolidation of participants and sales 
of participants or their businesses, and these trends might continue. Any concentration or sale 
within  the  wireless  industry  might  reduce  the  number  of  licensing  opportunities  or,  in  some 
instances,  result  in  the  loss  or  elimination  of  existing  royalty  obligations.  Further,  if  wireless 
carriers consolidate with companies that utilize technologies competitive with our technologies, 
we could lose market opportunities.

Approved Stock Repurchase Programs Might Not Result in a Positive Return of Capital to 
Stockholders and Might Expose Us to Counterparty Risk.  

Our  approved  stock  repurchases  might  not  return  value  to  stockholders  because  the  market 
price of the stock might decline significantly below the levels at which we repurchased shares 
of  stock.  Stock  repurchase  programs  are  intended  to  deliver  stockholder  value  over  the  long-
term, but stock price fluctuations can reduce the program’s effectiveness.

Unauthorized Use or Disclosure of Our Confidential Information Could Adversely Affect  
Our Business.

We  enter  into  contractual  relationships  governing  the  protection  of  our  confidential  and 
proprietary  information  with  our  employees,  consultants  and  prospective  and  existing 
customers  and  strategic  partners.  If  we  are  unable  to  timely  detect  the  unauthorized  use  or 
disclosure  of  our  proprietary  or  other  confidential  information  or  if  we  are  unable  to  enforce 
our  rights  under  such  agreements,  the  misappropriation  of  such  information  could  harm 
our business.

The Price of Our Common Stock Could Continue to be Volatile.

Historically,  we  have  had  large  fluctuations  in  the  price  of  our  common  stock,  and  such 
fluctuations  could  continue.  From  January  1,  2004  to  December  31,  2008,  our  common  stock 
has  traded  as  low  as  $13.81  per  share  and  as  high  as  $36.91  per  share.  Factors  that  might 
contribute to fluctuations in our stock price include, but are not limited to: general stock market 
conditions;  general  market  conditions  for  the  wireless  communications  industry;  changes  in 
recommendations  of  securities  analysts;  investor  perceptions  as  to  the  likelihood  of 
achievement  of  near-term  goals;  changes  in  market  share  of  significant  licensees; 
announcements concerning litigation, arbitration and other legal proceedings in which we are 
involved;  announcements  concerning  licensing  and  product  matters;  strategic  transactions, 
such as spin-offs, acquisitions or divestitures; and our operating results.

If Wireless Handsets Are Perceived to Pose Health and Safety Risks, Demand for Products of 
Our Licensees and Customers Could Decrease.

Media reports and certain studies have suggested that radio frequency emissions from wireless 
handsets  might  be  linked  to  health  concerns,  such  as  brain  tumors,  other  malignancies  and 
genetic  damage  to  blood,  and  might  interfere  with  electronic  medical  devices,  such  as 
pacemakers,  telemetry  and  delicate  medical  equipment.  Growing  concerns  over  radio 
frequency  emissions,  even  if  unfounded,  could  discourage  the  use  of  wireless  handsets  and 
cause  a  decrease  in  demand  for  the  products  of  our  licensees  and  customers.  In  addition, 
concerns  over  safety  risks  posed  by  the  use  of  wireless  handsets  while  driving  and  the  effect  
of  any  resulting  legislation  could  reduce  demand  for  the  products  of  our  licensees  
and customers.

Samsung Litigation and Settlement

As  described  in  more  detail  below  and  in  the  Company’s  prior  filings,  InterDigital 
Communications,  LLC  (“IDC”)  and  InterDigital Technology  Corp.  (“ITC”)  (“IDC”  and  “ITC” 
collectively referred to as “InterDigital”) and Samsung Electronics Co., Ltd. (“Samsung”) have 
been  engaged  in  a  series  of  arbitration  and  litigation  proceedings  concerning  royalties  owed 
for Samsung’s sales of 2G products under the 1996 Patent License Agreement between ITC and 
Samsung (the “1996 Samsung PLA”). In addition, as described in more detail below, InterDigital 
and Samsung have been engaged in litigation since March 2007 in the U.S. International Trade 
Commission  (“USITC”  or  the  “Commission”)  and  in  the  Delaware  District  Court  in  which 
InterDigital alleges that Samsung’s sales of 3G products infringe certain InterDigital patents.

On November 24, 2008, InterDigital and Samsung entered into a binding Term Sheet (“Samsung 
Term Sheet”) to settle their 2G and 3G disputes. On January 14, 2009, InterDigital and Samsung 
entered  into  a  patent  license  agreement  (the “2009  Samsung  PLA”),  which  superseded  the 
Samsung Term  Sheet,  and  which  also  superseded,  and  provided  for  the  termination  of,  the 
1996 Samsung PLA.

Under  the  terms  of  the  2009  Samsung  PLA,  Samsung  has  agreed  to  pay  InterDigital  $400.0 
million  in  four  equal  installments  over  an  18-month  period  to  resolve  the  parties’  disputes, 
including:  (a)  the  outstanding  arbitration  disputes  and  enforcement  proceedings  involving 
Samsung’s  sale  of  2G  products  (see  “Samsung  2nd  Arbitration  and  Related  Enforcement 
Proceeding” and “Samsung 3rd Arbitration” discussed below); and (b) the outstanding patent 
infringement  litigation  concerning  Samsung’s  sales  of  3G  products,  including  the  USITC 
Action  against  Samsung  and  the  related  Delaware  District  Court  proceeding  (described 
below).  In  addition,  the  2009  Samsung  PLA  provides  for  the  dismissal  of  a  separate 
pending  action  between  the  parties  in  the  Delaware  District  Court  (see “Samsung  Delaware 
Proceeding” below).

Samsung United States International Trade Commission Proceeding and Related Delaware 
District Court Proceeding

In  March  2007,  InterDigital,  Inc.’s  wholly-owned  subsidiaries  InterDigital  Communications,  LLC 
(“IDC”)  and  InterDigital Technology  Corporation  (“ITC”)  filed  a  Complaint  against  Samsung 
Electronics Co., Ltd. and certain of its affiliates (collectively, “Samsung”) in the USITC alleging 
that  Samsung  engages  in  unfair  trade  practices  by  selling  for  importation  into  the  United 
States,  importing  into  the  United  States,  and  selling  after  importation  into  the  United  States 

28       I N T E R D I G I TA L  2 0 0 8   A R

certain  3G  handsets  and  components  that  infringe  three  of  InterDigital’s  patents.  In  May  2007 
and December 2007, a fourth patent and fifth patent, respectively, were added to our Complaint 
against Samsung. The Complaint sought an exclusion order barring from entry into the United 
States  infringing  3G WCDMA  handsets  and  components  that  are  imported  by  or  on  behalf  of 
Samsung. The  Complaint  also  sought  a  cease  and  desist  order  to  bar  sales  of  infringing 
Samsung products that had already been imported into the United States.

On the same date as our filing of the Samsung USITC action referenced above, we also filed a 
Complaint  in  the  United  States  District  Court  for  the  District  of  Delaware  (“Delaware  District 
Court”)  alleging  that  Samsung’s  3G WCDMA  handsets  infringe  the  same  three  InterDigital 
patents identified in the original Samsung USITC Complaint. In June 2007, the Delaware District 
Court  entered  a  Stipulated  Order  staying  this  Delaware  District  Court  proceeding  against 
Samsung  until  the  USITC’s  determination  in  this  matter  becomes  final. The  Delaware  District 
Court  permitted  InterDigital  to  add  to  the  stayed  Delaware  action  the  fourth  and  fifth  patents 
InterDigital had asserted against Samsung in the USITC action.

As  described  more  fully  below  (see “Nokia  USITC  Proceeding  and  Related  Delaware  District 
Court  and  Southern  District  of  New York  Proceedings”),  in August  2007,  we  filed  a  Complaint 
against  Nokia  Corporation  and  Nokia,  Inc.  (collectively,  “Nokia”)  in  the  USITC  alleging 
that  Nokia  engaged  in  an  unfair  trade  practice  by  selling  for  importation,  importing  into  the 
United  States,  and  selling  after  importation  certain  3G  mobile  handsets  and  components  that 
infringe  two  of  InterDigital’s  patents.  On  October  24,  2007,  the  Administrative  Law  Judge 
overseeing  the  two  USITC  proceedings  against  Samsung  and  Nokia,  respectively,  issued  an 
Order consolidating the investigations pending against Samsung and Nokia. On May 16, 2008, 
the Administrative  Law  Judge  deconsolidated  the  investigations  against  Samsung  and  Nokia 
and  set  an  evidentiary  hearing  date  in  the  investigation  against  Samsung  to  begin  on  July  8, 
2008.  On  May  22,  2008,  the Administrative  Law  Judge  reset  the Target  Date  for  the  USITC’s 
Final  Determination  in  the  Samsung  investigation  (337-TA-601)  to  March  25,  2009,  requiring  a 
final  Initial  Determination  by  the  Administrative  Law  Judge  to  be  entered  no  later  than 
November 25, 2008.

On  June  24,  2008,  the  Administrative  Law  Judge  entered  summary  determination  in  the 
Samsung  investigation  (337-TA-601)  on  InterDigital’s  motion  that  InterDigital  has  satisfied  the 
domestic industry requirement based on its licensing activities. Samsung requested review of 
this  decision  by  the  full  Commission.  On  July  25,  2008,  the  full  Commission  issued  a  notice 
that it would not review the Administrative Law Judge’s Initial Determination that a licensing-
based domestic industry exists. As a result, the Administrative Law Judge’s Initial Determination 
of this issue has become the decision of the full Commission.

The  evidentiary  hearing  in  the  Samsung  investigation  commenced  on  July  8,  2008  and 
concluded on July 15, 2008.

Following the evidentiary hearing and the post-hearing filings, the Initial Determination of the 
Administrative  Law  Judge  was  expected  by  November  25,  2008  and  the Target  Date  for  the 
Final  Determination  of  the  USITC  was  expected  by  March  25,  2009,  but  these  dates  were 
modified. As referenced above, on November 24, 2008, InterDigital and Samsung entered into 
the  Samsung Term  Sheet.  Pursuant  to  the  Samsung Term  Sheet,  on  November  24,  2008,  the 
parties  jointly  filed  a  motion  with  the  USITC  in  the  Samsung  investigation  (337-TA-601) 
requesting  an  immediate  stay  of  the  procedural  schedule  and  seeking  to  reset  the  Initial 
Determination  date  to  February  9,  2009,  or  as  soon  thereafter  as  it  may  be  scheduled,  and  to 
reset  the Target  Date  for  the  Final  Determination  to  June  9,  2009,  or  as  soon  thereafter  as  it 
may  be  scheduled.  On  November  24,  2008,  the Administrative  Law  Judge  issued  an  Initial 
Determination  staying  the  current  procedural  schedule  and  resetting  the  Initial  Determination 
date  to  February  9,  2009  and  resetting  the Target  Date  for  the  Final  Determination  to  June  9,

2009.  On  December  9,  2008,  in  the  parallel  district  court  proceeding  in  the  Delaware  District 
Court proceeding against Samsung that is currently stayed, InterDigital and Samsung advised 
the Delaware District Court of the Samsung Term Sheet.

On  January  14,  2009,  InterDigital  and  Samsung  entered  into  the  2009  Samsung  PLA,  which 
superseded the terms of the Samsung Term Sheet. Under the terms of the 2009 Samsung PLA, 
Samsung  has  agreed  to  pay  InterDigital  $400.0  million  in  four  equal  installments  over  an 
18-month  period  to  resolve  their  outstanding  disputes,  including  the  USITC Action  against 
Samsung  and  the  related  Delaware  District  Court  proceeding.  Under  the  terms  of  the  2009 
Samsung  PLA,  InterDigital  has  agreed  to  grant  Samsung  a  royalty-bearing  license  covering 
Samsung’s sale of 3G products (including products built under both the WCDMA and cdma2000 
standards  and  certain  of  their  related  extensions)  through  2012,  and  a  license  covering 
Samsung’s sale of 2G single-mode TDMA-based products that will become paid-up in 2010.

On January 30, 2009, Samsung made its first required payment under the 2009 Samsung PLA, 
and on February 3, 2009 the parties jointly moved to terminate the Samsung USITC Action. On 
February  6,  2009,  the Administrative  Law  Judge  terminated  the  USITC Action.  On  February  3, 
2009,  the  court  in  the  related  Delaware  District  Court  proceeding  dismissed  that  action 
following a joint stipulation of dismissal filed by the parties on February 2, 2009.

Samsung Delaware Proceeding

In  March  2007,  Samsung Telecommunications America  LLP  and  Samsung  Electronics  Co.,  Ltd. 
(collectively “Samsung”) filed an action against InterDigital Communications Corporation (now 
IDC), ITC and another affiliate, Tantivy Communications, Inc. (collectively “InterDigital”), in the 
Delaware  District  Court  (the “Samsung  Delaware  Proceeding”),  alleging  that  InterDigital  had 
refused to comply with its alleged contractual obligations to be prepared to license our patents 
on fair, reasonable, and non-discriminatory (“FRAND”) terms and that InterDigital had allegedly 
engaged  in  unfair  business  practices.  By  their  original  Complaint  in  the  action,  Samsung 
sought damages and declaratory relief, including declarations that: (i) InterDigital’s patents and 
patent applications allegedly promoted to standards bodies are unenforceable, (ii) the Samsung 
entities  have  a  right  to  practice  InterDigital’s  intellectual  property  as  a  result  of  an  alleged 
license from QUALCOMM Incorporated, (iii) nine specified InterDigital patents are invalid and/
or not infringed by the Samsung entities, and (iv) InterDigital must offer the Samsung entities a 
license  on  FRAND  terms.  In  September  2007,  Samsung  filed  a  First Amended  Complaint  that 
omitted  the  previously  asserted  claims  for  declaratory  judgment  regarding  the  nine  specified 
InterDigital patents. In November 2007, InterDigital filed its Answer to the Amended Complaint, 
disputing  Samsung’s  allegations  and  asserting  counterclaims  of  infringement  as  to  two 
InterDigital patents.

As  discussed  above,  in  November  2008,  InterDigital  and  Samsung  entered  into  the  Samsung 
Term Sheet resolving their disputes. Pursuant to the Samsung Term Sheet, in December 2008, 
Samsung  and  InterDigital  filed  a  joint  stipulation  to  stay  the  Samsung  Delaware  Proceeding 
until  February  9,  2009,  which  was  granted.  On  January  14,  2009,  InterDigital  and  Samsung 
entered into the 2009 Samsung PLA, superseding the Samsung Term Sheet and providing for, 
among other things, the dismissal of the Samsung Delaware Proceeding.

On January 30, 2009, Samsung made its first required payment under the 2009 Samsung PLA. 
Thereafter, on February 2, 2009, the parties jointly moved to dismiss this matter. On February 3, 
2009, the court in the Samsung Delaware Proceeding dismissed that action.

Samsung 2nd Arbitration and Related Enforcement Action

Since  February  2002,  InterDigital  and  Samsung  Electronics  Co.,  Ltd.  (“Samsung”)  have  been 
engaged  in  a  series  of  disputes  concerning  the  royalties  owed  by  Samsung  for  sales  of  2G 
products  under  the  parties’  1996  patent  license  agreement.  In  November  2003,  Samsung 

30       I N T E R D I G I TA L  2 0 0 8   A R

initiated  an  arbitration  proceeding  with  InterDigital  (the “Samsung  2nd Arbitration”)  in  the 
International  Chamber  of  Commerce  concerning  the  royalties  owed  by  Samsung  on  sales  of 
2G  products  during  the  2002  to  2006  timeframe.  In  August  2006,  the  arbitral  tribunal 
(“Tribunal”) in the Samsung 2nd Arbitration issued a final award (“Award”), ordering Samsung 
to  pay  InterDigital  approximately  $134.0  million  in  past  royalties,  plus  interest,  on  Samsung’s 
sale  of  single  mode  2G  GSM/TDMA  and  2.5G  GSM/GPRS/EDGE  terminal  units  for  the  period 
from  2002  through  2005. The Tribunal  also  established  the  royalty  rates  to  be  applied  to 
Samsung’s sales of covered 2G products in 2006.

In September 2006, InterDigital filed an action seeking to enforce the arbitral Award in the U.S. 
District  Court  for  the  Southern  District  of  New York  (“Enforcement Action”).  On  December  10, 
2007, the court in the Enforcement Action confirmed the Award in its entirety and directed that 
Samsung  pay  InterDigital  the  amount  of  the Award,  plus  interest,  for  a  total  judgment  of 
approximately $150.3 million. On December 18, 2007, Samsung filed an appeal with the United 
States  Court  of Appeals  for  the  Second  Circuit,  and  posted  an  appeal  bond  with  the  district 
court  in  the  amount  of  approximately  $166.7  million.  By  posting  the  appeal  bond,  Samsung 
stayed  execution  of  the  Order  of  Judgment  pending  the  appeal.  Oral  argument  in  the  appeal 
was scheduled for December 17, 2008.

As  discussed  above,  in  November  2008,  InterDigital  and  Samsung  entered  into  the  Samsung 
Term  Sheet,  settling  their  2G  and  3G  disputes.  Pursuant  to  the  Samsung Term  Sheet,  in 
December  2008,  Samsung  and  InterDigital  filed  a  joint  request  to  stay  the  appeal  in  the 
Enforcement Action.  On  January  14,  2009,  InterDigital  and  Samsung  entered  into  the  2009 
Samsung  PLA,  which  superseded  the  Samsung Term  Sheet  and  provided  for,  among  other 
things,  the  dismissal  of  the  2G  disputes,  including  the  appeal  of  the  Enforcement Action.  On 
January 30, 2009, Samsung made its first required payment under the 2009 Samsung PLA. On 
February  3,  2009,  the  parties  jointly  moved  to  dismiss  the  appeal  of  the  Enforcement Action, 
and  to  release  the  appeal  bond  posted  by  Samsung.  On  February  5,  2009,  the  Second  Circuit 
granted the parties’ dismissal request.

Samsung 3rd Arbitration

In  October  2006,  Samsung  Electronics  Co.,  Ltd.  (“Samsung”)  filed  a  Request  for Arbitration 
(“Samsung 3rd Arbitration”) with the International Chamber of Commerce against InterDigital 
relating to the royalties Samsung owed for the period 2002 through 2006, which had been the 
subject  of  the  Samsung  2nd Arbitration.  In  the  Samsung  3rd Arbitration,  Samsung  sought  to 
have a new arbitration panel determine new royalty rates for Samsung’s 2G/2.5G GSM/GPRS/
EDGE  product  sales  based  on  the  April  2006  Arbitration  Settlement  Agreement  between 
InterDigital  and  Nokia  (“Nokia  Settlement”).  Samsung  purported  to  have  elected  the  Nokia 
Settlement under the most favored licensee (“MFL”) clause in the 1996 Samsung PLA. Samsung 
contended that it had the right to have a new rate, based on the Nokia Settlement, applied to 
its  sales  in  the  period  from  January  1,  2002  through  December  31,  2006  in  lieu  of  the  royalty 
rates that had been determined by the Tribunal in the Samsung 2nd Arbitration for that period. 
InterDigital  denied  that  Samsung  was  entitled  to  receive  any  new  royalty  rate  adjustment 
based  on  the  Nokia  Settlement,  and  counterclaimed,  seeking  an  Award  of  the  royalties 
Samsung  owes  for  its  2G/2.5G  sales  in  2006  at  the  royalty  rate  specified  in  the August  2006 
Award in the Samsung 2nd Arbitration.

In  February  2008,  the  arbitral  tribunal  heard  oral  argument  on  the  issue  of  whether  Samsung 
was  entitled  to  elect  the  Nokia  Settlement.  In  July  2008,  the  arbitral  tribunal  in  the  Samsung 
3rd  Arbitration  issued  a  Partial  Final  Award,  finding  that  Samsung  was  not  entitled  to  an 
adjustment of its royalty obligations based on the Nokia Settlement.

I N T E R D I G I TA L  2 0 0 8   A R   31

As  discussed  above  with  respect  to  the  USITC Action,  in  November  2008,  InterDigital  and 
Samsung entered into the Samsung Term Sheet settling their 2G and 3G disputes. Pursuant to 
the Samsung Term Sheet, in December 2008, Samsung and InterDigital filed a joint request to 
stay the Samsung 3rd Arbitration. On January 14, 2009, InterDigital and Samsung entered into 
the 2009 Samsung PLA, which superseded the Samsung Term Sheet and provided for, among 
other  things,  the  dismissal  of  the  2G  disputes,  including  the  Samsung  3rd Arbitration.  On 
January 30, 2009, Samsung made its first required payment under the 2009 Samsung PLA, and 
on  February  2,  2009,  the  parties  jointly  moved  to  dismiss  the  Samsung  3rd Arbitration.  On 
February 19, 2009, the arbitral tribunal in the Samsung 3rd Arbitration issued an Agreed Order 
dismissing the arbitration.

Nokia Litigation

Nokia USITC Proceeding and Related Delaware District Court and Southern District of New 
York Proceedings

In August 2007, InterDigital filed a USITC Complaint against Nokia Corporation and Nokia, Inc. 
(collectively, “Nokia”)  alleging  that  Nokia  engaged  in  an  unfair  trade  practice  by  selling  for 
importation  into  the  United  States,  importing  into  the  United  States,  and  selling  after 
importation  into  the  United  States,  certain  3G  mobile  handsets  and  components  that  infringe 
two of InterDigital’s patents. In November and December 2007, a third patent and fourth patent, 
respectively,  were  added  to  our  Complaint  against  Nokia. The  Complaint  seeks  an  exclusion 
order barring from entry into the United States infringing 3G mobile handsets and components 
that are imported by or on behalf of Nokia. Our Complaint also seeks a cease-and-desist order 
to  bar  further  sales  of  infringing  Nokia  products  that  have  already  been  imported  into  the 
United States.

In addition, on the same date as our filing of the USITC action referenced above, we also filed 
a  Complaint  in  the  Delaware  District  Court  alleging  that  Nokia’s  3G  mobile  handsets  and 
components  infringe  the  same  two  InterDigital  patents  identified  in  the  original  USITC 
Complaint. This  Delaware  action  was  stayed  on  January  10,  2008,  pursuant  to  the  mandatory, 
statutory  stay  of  parallel  district  court  proceedings  at  the  request  of  a  respondent  in  a  USITC 
investigation. Thus, this Delaware action is stayed until the USITC’s determination in this matter 
becomes final. The Delaware District Court permitted InterDigital to add to the stayed Delaware 
action the third and fourth patents InterDigital asserted against Nokia in the USITC action.

Nokia, joined by Samsung, moved to consolidate the Samsung and Nokia USITC proceedings. 
On October 24, 2007, the Honorable Paul J. Luckern, the Administrative Law Judge overseeing 
the  two  USITC  proceedings  against  Samsung  and  Nokia,  respectively,  issued  an  Order  to 
consolidate  the  two  pending  investigations.  Pursuant  to  the  Order,  the  schedules  for  both 
investigations were revised to consolidate proceedings and set a unified evidentiary hearing on 
April 21-28, 2008, the filing of a single initial determination by Judge Luckern by July 11, 2008, 
and a target date for the consolidated investigations of November 12, 2008, by which date the 
USITC would issue its final determination (the “Target Date”).

On  December  4,  2007,  Nokia  moved  for  an  order  terminating  or,  alternatively,  staying  the 
USITC investigation as to Nokia, on the ground that Nokia and InterDigital must first arbitrate a 
dispute as to whether Nokia is licensed under the patents asserted by InterDigital against Nokia 
in the USITC investigation. On January 8, 2008, Judge Luckern issued an order denying Nokia’s 
motion and holding that Nokia has waived its arbitration defense by instituting and participating 
in the investigation and other legal proceedings. On February 13, 2008, Nokia filed an action in 
the  U.S.  District  Court  for  the  Southern  District  of  New York,  seeking  to  preliminarily  enjoin 
InterDigital  from  proceeding  with  the  USITC  investigation  with  respect  to  Nokia,  in  spite  of 
Judge  Luckern’s  ruling  denying  Nokia’s  motion  to  terminate  the  USITC  investigation.  Nokia 

32       I N T E R D I G I TA L  2 0 0 8   A R

raised  in  this  preliminary  injunction  action  the  same  arguments  it  raised  in  its  motion  to 
terminate  the  USITC  investigation,  namely  that  InterDigital  allegedly  must  first  arbitrate  its 
alleged license dispute with Nokia and that Nokia has not waived arbitration of this defense. In 
the  Southern  District Action,  Nokia  also  sought  to  compel  InterDigital  to  arbitrate  its  alleged 
license  dispute  with  Nokia  and,  in  the  alternative,  seeks  a  determination  by  the  District  Court 
that  Nokia  is  licensed  under  the  patents  asserted  by  InterDigital  against  Nokia  in  the  USITC 
investigation.  On  March  7,  2008,  InterDigital  filed  a  motion  to  dismiss  Nokia’s  claim  in  the 
alternative that Nokia is licensed under the patents asserted by InterDigital against Nokia in the 
USITC investigation. The District Court has not acted on InterDigital’s motion to dismiss.

On  February  8,  2008,  Nokia  filed  a  motion  for  summary  determination  in  the  USITC  that 
InterDigital  cannot  show  that  a  domestic  industry  exists  in  the  United  States  as  required  to 
obtain  relief.  Samsung  joined  this  motion.  InterDigital  opposed  this  motion.  On  February  14, 
2008,  InterDigital  filed  a  motion  for  summary  determination  that  InterDigital  satisfies  the 
domestic  industry  requirement  based  on  its  licensing  activities.  On  February  26,  2008, 
InterDigital  filed  a  motion  for  summary  determination  that  it  has  separately  satisfied  the 
so-called  “economic  prong”  for  establishing  that  a  domestic  industry  exists  based  on 
InterDigital’s chipset product that practices the asserted patents. Samsung and Nokia opposed 
these  motions.  On  March  17,  2008,  Samsung  and  Nokia  filed  a  motion  to  strike  any  evidence 
concerning  InterDigital’s  product  and  to  preclude  InterDigital  from  introducing  any  such 
evidence  in  relation  to  domestic  industry  at  the  evidentiary  hearing.  On  March  26,  2008,  the 
Administrative Law Judge granted InterDigital’s motion for summary determination that it has 
satisfied the so-called “economic prong” for establishing that a domestic industry exists based 
on  InterDigital’s  chipset  product  that  practices  the  asserted  patents  and  denied  Samsung’s 
motion  to  strike  and  preclude  introduction  of  evidence  concerning  InterDigital’s  domestic 
industry product.

On February 27, 2008, Nokia filed a motion to extend the Target Date in the USITC proceeding. 
Samsung  joined  Nokia’s  motion.  InterDigital  opposed  this  motion.  On  March  11,  2008,  the 
Administrative Law Judge denied Nokia’s motion to extend the Target Date.

On  March  17,  2008,  Nokia  and  Samsung  jointly  moved  for  summary  determination  that  
U.S.  Patent  No.  6,693,579,  which  was  asserted  against  both  Samsung  and  Nokia,  is  invalid,  
and  Samsung  moved  for  summary  determination  on  its  defense  of  equitable  estoppel. 
InterDigital  opposed  these  motions.  On April  14,  2008,  the Administrative  Law  Judge  denied 
Nokia’s and Samsung’s joint motion for summary determination that the ‘579 patent is invalid 
and  also  denied  Samsung’s  motion  for  summary  determination  of  Samsung’s  defense  of 
equitable estoppel.

On March 20, 2008, the U.S. District Court for the Southern District of New York, ruling from the 
bench, decided that Nokia is likely to prevail on the issue of whether Nokia’s alleged entitlement 
to a license is arbitrable. The Court did not consider or rule on whether Nokia is entitled to such  
a  license. As  a  result,  the  Court  ordered  InterDigital  to  participate  in  arbitration  of  the  license 
issue. The  Court  also  entered  a  preliminary  injunction  requiring  InterDigital  to  cease 
participation  in  the  USITC  proceeding  by April  11,  2008,  but  only  with  respect  to  Nokia. The 
Court further ordered Nokia to post a $500,000 bond by March 28, 2008. InterDigital promptly 
filed  a  request  for  a  stay  of  the  preliminary  injunction  and  for  an  expedited  appeal  with  the 
U.S. Court of Appeals for the Federal Circuit, which transferred the appeal to the U.S. Court of 
Appeals  for  the  Second  Circuit. The  preliminary  injunction  became  effective  on April  11,  2008, 
and,  in  accordance  with  the  Court’s  order,  InterDigital  filed  a  motion  with  the Administrative 
Law  Judge  to  stay  the  USITC  proceeding  against  Nokia  pending  InterDigital’s  appeal  of  the 
District  Court’s  decision  or,  if  that  appeal  is  unsuccessful,  pending  the  Nokia TDD Arbitration 
(described  below).  On April  14,  2008,  the Administrative  Law  Judge  ordered  that  the  date  for 
the  commencement  of  the  evidentiary  hearing,  originally  scheduled  for April  21,  2008,  be 

I N T E R D I G I TA L  2 0 0 8   A R   33

suspended  until  further  notice  from  the Administrative  Law  Judge. The Administrative  Law 
Judge  did  not  at  that  point  change  the  scheduled  date  of  July  11,  2008  for  his  initial 
determination  in  the  investigation  or  the  scheduled Target  Date  of  November  12,  2008  for  a 
decision by the USITC. InterDigital’s motion for a stay of the preliminary injunction and for an 
expedited appeal was considered by a panel of the Second Circuit on April 15, 2008. On April 
16, 2008, the Second Circuit denied the motion for stay but set an expedited briefing schedule 
for  resolving  InterDigital’s  appeal  on  the  merits  of  whether  the  District  Court’s  order  granting 
the preliminary injunction should be reversed.

On April  17,  2008,  InterDigital  filed  a  motion  with  the  USITC  to  separate  the  consolidated 
investigations  against  Nokia  and  Samsung  in  order  for  the  investigation  to  continue  against 
Samsung  pending  the  expedited  appeal  or,  if  the  appeal  is  unsuccessful,  pending  the  Nokia 
TDD Arbitration.  Samsung  and  Nokia  opposed  InterDigital’s  motion.  On  May  16,  2008,  the 
Administrative  Law  Judge  deconsolidated  the  investigations  against  Samsung  and  Nokia  and 
set an evidentiary hearing date in the investigation against Samsung (337-TA-601) to begin on 
July 8, 2008.

On May 20, 2008, the Administrative Law Judge denied without prejudice all pending motions 
in the consolidated investigation (337-TA-613). On May 22, 2008, the Administrative Law Judge 
reset the Target Date for the USITC’s Final Determination in the Samsung investigation (337-TA-
601) to March 25, 2009, requiring a final Initial Determination by the Administrative Law Judge 
to be entered no later than November 25, 2008.

On  June  17,  2008,  a  panel  of  the  U.S.  Court  of  Appeals  for  the  Second  Circuit  heard  oral 
argument  on  InterDigital’s  appeal  from  the  Order  of  the  U.S.  District  Court  for  the  Southern 
District  of  New York  preliminarily  enjoining  InterDigital  from  proceeding  against  Nokia  in  the 
consolidated  investigation.  On  July  31,  2008,  the  Second  Circuit  reversed  the  preliminary 
injunction, finding that Nokia’s litigation conduct resulted in a waiver of any right to arbitrate its 
license  dispute.  InterDigital  promptly  notified  the  Administrative  Law  Judge  in  the  Nokia 
investigation  (337-TA-613)  of  the  Second  Circuit’s  decision.  On August  14,  2008,  Nokia  filed  a 
petition  for  rehearing  and  petition  for  rehearing  en  banc  of  the  Second  Circuit’s  decision,  and 
on  September  15,  2008,  the  Second  Circuit  denied  Nokia’s  petitions. The  mandate  from  the 
Second  Circuit  issued  to  the  Southern  District  of  New York  on  September  22,  2008. 
Notwithstanding the Second Circuit’s decision, on October 17, 2008 Nokia filed a request for a 
status conference with the District Court to establish a procedural schedule for Nokia to pursue 
a  permanent  injunction  requiring  InterDigital  to  arbitrate  Nokia’s  alleged  license  defense,  and 
arguing  that  the  Second  Circuit’s  decision  was  rendered  in  the  context  of  a  preliminary 
injunction and does not bar such an action. On October 23, 2008, InterDigital filed a response 
with  the  District  Court  asserting  that  the  Second  Circuit’s  waiver  finding  is  dispositive  of  any 
claim  for  arbitration  of  Nokia’s  alleged  license  defense  and  requesting  the  District  Court  to 
address InterDigital’s entitlement to recover against the $500,000 bond posted by Nokia as well 
as InterDigital’s pending motion to dismiss Nokia’s claim in the alternative for a determination 
by  the  District  Court  that  Nokia  is  licensed  under  the  patents  asserted  by  InterDigital  against 
Nokia  in  the  USITC  investigation.  On  October  30,  2008,  Nokia  filed  a  reply  with  the  District 
Court. The District Court has not yet acted on the parties’ filings.

On  September  24,  2008,  InterDigital  filed  a  motion  to  lift  the  stay  of  the  Nokia  investigation 
(337-TA-613) based on the issuance of the Second Circuit’s mandate reversing the preliminary 
injunction  granted  to  Nokia. The Administrative  Law  Judge  granted  InterDigital’s  motion  on 
September  25,  2008  and  lifted  the  stay.  On  October  7,  2008,  the Administrative  Law  Judge 
issued an Order in the Nokia investigation setting the evidentiary hearing for May 26-29, 2009. 
On  October  10,  2008,  the Administrative  Law  Judge  issued  an  Order  resetting  the Target  Date 

34       I N T E R D I G I TA L  2 0 0 8   A R

for  the  USITC’s  Final  Determination  in  the  Nokia  investigation  to  December  14,  2009,  and 
requiring  a  final  Initial  Determination  by  the Administrative  Law  Judge  to  be  entered  no  later 
than August 14, 2009.

On  January  21,  2009,  Nokia  filed  a  motion  to  schedule  a  claim  construction  hearing  in  early 
February  2009,  and  on  January  29,  2009,  InterDigital  filed  an  opposition  to  the  motion  for  a 
claim construction hearing. On February 9, 2009, the Administrative Law Judge denied Nokia’s 
motion for a claim construction hearing.

On  February  13,  2009,  InterDigital  filed  a  renewed  motion  for  summary  determination  that 
InterDigital  has  satisfied  the  domestic  industry  requirement  based  on  its  licensing  activities, 
and on February 27, 2009, Nokia filed an opposition to the motion. The parties await a ruling on 
this summary determination motion by the Administrative Law Judge.

The  evidentiary  hearing  for  the  Nokia  investigation  (337-TA-613)  remains  scheduled  for  
May 26-29, 2009.

Nokia TDD Arbitration

On  April  1,  2008,  Nokia  Corporation  filed  a  Request  for  Arbitration  with  the  International 
Chamber of Commerce against InterDigital, Inc., IDC and ITC, seeking a declaration that Nokia 
is licensed under the patents asserted by InterDigital against Nokia in the USITC investigation 
pursuant to the parties’ TDD Development Agreement. InterDigital believes that Nokia’s request 
for declaratory relief in the TDD Arbitration is meritless.

On  May  9,  2008,  InterDigital  filed  an Answer  to  Nokia’s  Request  for Arbitration,  requesting, 
inter alia : (i) that the arbitration be dismissed because the dispute is not arbitrable and, even if 
arbitrable,  Nokia  waived  its  right  to  arbitration;  and,  in  the  alternative,  (ii)  a  declaration  that 
Nokia is not licensed to the patents at issue in the USITC investigation pursuant to the parties’ 
TDD Development Agreement.

On July 17, 2008, the arbitral tribunal was constituted.

On July 31, 2008, as discussed above, the United States Court of Appeals for the Second Circuit 
reversed the district court’s grant of an order requiring InterDigital to submit the TDD issue to 
arbitration, finding that Nokia waived any right to arbitrate the issue. InterDigital believes that 
Nokia  should  not  be  permitted  to  continue  to  pursue  this  arbitration  in  light  of  the  Second 
Circuit’s  finding  of  waiver  and  has  requested  that  the  arbitration  be  dismissed.  Nokia  has 
asserted  that  the  Second  Circuit’s  decision  is  not  a  final  decision  on  the  issue  of  waiver,  and 
that  Nokia  may  submit  the  waiver  issue  to  the  arbitral  tribunal  or,  as  indicated  above,  to  the 
District Court on remand. On October 27, 2008, the arbitral tribunal notified the parties that the 
drafting of the Terms of Reference for the arbitration is postponed until such time as the status 
conference  before  Judge  Batts  in  the  U.S.  District  Court  for  the  Southern  District  of  New York 
has been held (see “Nokia USITC Proceeding and Related Delaware District Court and Southern 
District of New York Proceedings” above).

Nokia Delaware Proceeding

In  January  2005,  Nokia  filed  a  Complaint  in  the  United  States  District  Court  for  the  District  of 
Delaware  (“Delaware  District  Court”)  against  InterDigital  Communications  Corporation  (now 
IDC) and ITC (for purposes of the Nokia Delaware Proceeding described herein, IDC and ITC are 
collectively  referred  to  as “InterDigital,” “we,”  or “our”),  alleging  that  we  have  used  false  or 
misleading  descriptions  or  representations  regarding  our  patents’  scope,  validity,  and 
applicability  to  products  built  to  comply  with  3G  wireless  phone  Standards  (“Nokia  Delaware 
Proceeding”). We subsequently filed counterclaims based on Nokia’s licensing activities as well 

I N T E R D I G I TA L  2 0 0 8   A R   35

as Nokia’s false or misleading descriptions or representations regarding Nokia’s 3G patents and 
Nokia’s undisclosed funding and direction of an allegedly independent study of the essentiality 
of 3G patents.

On  December  10,  2007,  pursuant  to  a  joint  request  by  the  parties,  the  Delaware  District  Court 
entered an Order staying the proceedings pending the full and final resolution of the Company’s 
USITC investigation against Nokia and Samsung. Specifically, the full and final resolution of the 
USITC investigation includes any initial or final determinations of the Administrative Law Judge 
overseeing the proceeding, the USITC, and any appeals therefrom. Pursuant to the Order, the 
parties  and  their  affiliates  are  generally  prohibited  from  initiating  against  the  other  parties,  in 
any  forum,  any  claims  or  counterclaims  that  are  the  same  as  the  claims  and  counterclaims 
pending  in  the  Nokia  Delaware  Proceeding,  and  should  any  of  the  same  or  similar  claims  or 
counterclaims be initiated by a party, the other parties may seek dissolution of the stay.

Except for the Nokia Delaware Proceeding and the Nokia Arbitration Concerning Presentations 
(described  below),  the  Order  does  not  affect  any  of  the  other  legal  proceedings  between  the 
parties,  including  the  USITC  investigation  involving  InterDigital  and  Nokia,  or  the  parallel 
Delaware District Court proceeding also brought by InterDigital against Nokia.

Nokia Arbitration Concerning Presentations

In November 2006, InterDigital Communications Corporation (now IDC) and ITC filed a Request 
for Arbitration with the International Chamber of Commerce against Nokia (“Nokia Arbitration 
Concerning Presentations”), claiming that certain presentations Nokia has attempted to use in 
support  of  its  claims  in  the  Nokia  Delaware  Proceeding  are  confidential  and,  as  a  result,  may 
not be used in the Nokia Delaware Proceeding pursuant to the parties’ agreement.

The  December  10,  2007  Order  entered  by  the  Delaware  District  Court  to  stay  the  Nokia 
Delaware  Proceeding  (described  above)  also  stayed  the  Nokia  Arbitration  Concerning 
Presentations pending the full and final resolution of the USITC investigation against Nokia as 
described above.

Other

We  have  filed  patent  applications  in  the  United  States  and  in  numerous  foreign  countries.  In 
the ordinary course of business, we currently are, and expect from time-to-time to be, subject 
to  challenges  with  respect  to  the  validity  of  our  patents  and  with  respect  to  our  patent 
applications. We intend to continue to vigorously defend the validity of our patents and defend 
against any such challenges. However, if certain key patents are revoked or patent applications 
are denied, our patent licensing opportunities could be materially and adversely affected.

We  and  our  licensees,  in  the  normal  course  of  business,  may  have  disagreements  as  to  the 
rights and obligations of the parties under the applicable patent license agreement. For example, 
we  could  have  a  disagreement  with  a  licensee  as  to  the  amount  of  reported  sales  of  covered 
products and royalties owed. Our patent license agreements typically provide for arbitration as 
the  mechanism  for  resolving  disputes. Arbitration  proceedings  can  be  resolved  through  an 
award rendered by an arbitration panel or through private settlement between the parties.

In  addition  to  disputes  associated  with  enforcement  and  licensing  activities  regarding  our 
intellectual property, including the litigation and other proceedings described above, we are a 
party to other disputes and legal actions not related to our intellectual property, but also arising 
in the ordinary course of our business, including claims by us for insurance coverage involving 
the Nokia Delaware Proceeding. Based upon information presently available to us, we believe 
that  the  ultimate  outcome  of  these  other  disputes  and  legal  actions  will  not  have  a  material 
adverse affect on us.

Among the types of legal proceedings we encounter in the normal course of business, we are 
engaged in the following action:

Federal

In May 2007, the Arbitrator in the arbitration proceeding between InterDigital Communications 
Corporation  (now  IDC)  and  ITC  (collectively,  for  purposes  of  the  Federal  arbitration  described 
herein, “InterDigital,” “we,” or “our”) and Federal Insurance Company (“Federal”), and relating 
to a Litigation Expense and Reimbursement Agreement signed in February 2000 by the parties 
(“Reimbursement Agreement”), refused to award the full amount of Federal’s claim, which was 
in  excess  of  $33.0  million. The  Arbitrator  did  award  Federal  approximately  $13.0  million, 
pursuant  to  a  formula  set  forth  in  the  Reimbursement  Agreement,  for  reimbursement  of 
attorney’s  fees  and  expenses  previously  paid  to  or  on  behalf  of  InterDigital  by  Federal,  plus 
approximately  $2.0  million  in  interest. As  additional  reimbursement  of  attorney’s  fees  and 
expenses,  the Arbitrator  awarded  $5.0  million,  without  interest,  as  Federal’s  share  under  the 
Reimbursement Agreement  of “additional  value”  of  the  2003  settlement  between  InterDigital 
and  Ericsson  Inc.  Further,  the Arbitrator  ruled  that  InterDigital  must  pay  Federal  10%  of  any 
additional payments InterDigital may receive as a result of an audit of Sony Ericsson’s sales. In 
June 2007, we notified Federal that we had received $2.0 million from Sony Ericsson to resolve 
Sony  Ericsson’s  payment  obligations  following  an  audit. The  approximately  $13.0  million 
portion  of  the Award  represents  a  percentage  of  the  amounts  InterDigital  has  received  since 
March 2003 from Telefonaktiebolaget LM Ericsson and Ericsson Inc. and Sony Ericsson Mobile 
Communications AB under their respective patent license agreements.

In  June  2007,  Federal  moved  to  confirm  the Award  in  the  United  States  District  Court  for  the 
Eastern District of Pennsylvania. Also in June 2007, we filed an opposition to Federal’s motion 
to confirm the arbitration Award and a cross motion to vacate a portion of the Award, totaling 
approximately  $14.5  million,  on  the  ground  that  the Arbitrator  exceeded  the  scope  of  her 
authority. We also moved the Court to stay confirmation of the Award pending adjudication of 
our  recoupment  defense  whereby  we  are  seeking  to  recoup  the  full  amount  of  the Award 
based  on  Federal’s  bad  faith  breach  of  its  contractual  and  fiduciary  duties  to  us.  In  July  2007, 
the  Court  heard  oral  arguments  on  Federal’s  motion  to  confirm  the Award,  our  opposition 
thereto,  and  our  cross  motion  to  vacate  the  Award  and  to  stay  confirmation  pending 
adjudication  of  our  recoupment  defense.  On  March  24,  2008,  the  Court:  (i)  granted  Federal’s 
motion  to  confirm  the  arbitration  award;  and  (ii)  denied  InterDigital’s  motion  to  stay 
confirmation  of  the  arbitration  award  pending  adjudication  of  InterDigital’s  claim  for 
recoupment based on Federal’s bad faith breach of its duties as InterDigital’s insurer. On April 
1, 2008, InterDigital filed a notice of appeal to the United States Court of Appeals for the Third 
Circuit. In order to stay execution on Federal’s judgment pending appeal, InterDigital deposited 
$23.0 million with the Clerk of the Court, an amount sufficient to secure Federal’s judgment and 
anticipated interest until decision by the Court of Appeals. On April 10, 2008, the Court extended 
Federal’s deadline for seeking costs and fees until after conclusion of the appeal.

On May 6, 2008, the Court of Appeals assigned the matter for mediation in the Court of Appeals 
mediation  program. The  mediation  program  concluded  without  any  settlement.  Consequently, 
InterDigital and Federal have commenced briefing the appeal.

On  July  7,  2008,  the  Company  filed  its  opening  brief,  seeking  reversal  of  the  District  Court’s 
refusal to hear InterDigital’s recoupment claim and remand to the District Court for adjudication 
of  such  claim  as  a  set-off  to  Federal’s  arbitration  award.  Federal’s  brief  was  filed  on August  6, 
2008. The Company’s reply brief was filed on August 20, 2008. The appeal was submitted to the 
Court of Appeals on January 8, 2009. On January 29, 2009, the Court of Appeals affirmed the 
District  Court’s  March  24,  2008  Order.  On  February  23,  2009,  Federal  moved  to  lift  the  stay  of 
enforcement of Federal’s judgment.

the  foreseeable  future,  without  regard  to  any  cash  proceeds  we  may  receive  from  any 
settlement  or  resolution  of  outstanding  arbitrations  or  litigations,  no  cash  dividends  will  be 
paid  on  our  common  stock  and  any  cash  otherwise  available  for  such  dividends  will  be 
reinvested  in  our  business  or  used  to  repurchase  our  common  stock. When  considering 
whether  or  not  to  pay  cash  dividends,  our  Board  of  Directors  assesses  our  earnings,  any

(a)   In 2006, we recognized $253.0 million of revenue related to the resolution of disputes with Nokia regarding our 1999 Patent License 
Agreement. In third quarter 2004, we transitioned to reporting per-unit royalties in the period in which we receive our licensees’ royalty 
reports rather than in the period in which our licensees’ sales of covered products occur. As a result of this transition, our results for 2004 
include only three quarters of per-unit royalties.

(b)   In 2008, the Company recognized a $3.9 million non-recurring benefit associated with a reduction in a contingent liability, and in 2007, the 
Company recognized non-recurring charges totaling $24.4 million associated with increases to contingent liabilities. In 2005 and 2004, 
our income (loss) from operations included charges of $1.5 million and $0.6 million, respectively, associated with actions to reposition the 
Company’s operations.

(c)   Our income tax provision in 2005 included a benefit of approximately $43.7 million, primarily related to the fourth quarter 2005 reversal 
of our Federal deferred tax asset valuation allowance. Our income tax provision in 2004 included a benefit of approximately $17.0 million 
related to the third quarter 2004 partial reversal of our Federal deferred tax asset valuation allowance.

Overview

The  following  discussion  should  be  read  in  conjunction  with  the  Selected  Financial  Data,  the 
Consolidated  Financial  Statements  and  the  notes  thereto  contained  in  this  document.  Please 
refer  to  the  Glossary  of Terms  immediately  following  the Table  of  Contents  for  a  listing  and 
detailed description of the various technical, industry and other defined terms that are used in 
this Annual Report.

Samsung Settlement

On  January  14,  2009,  we  entered  into  a  patent  license  agreement  (the “2009  Samsung  PLA”) 
with  Samsung  Electronics  Co.,  Ltd.  (“Samsung”)  covering  Samsung’s  affiliates,  including 
Samsung  Electronics America,  Inc. The  agreement  supersedes  the  terms  of  the  binding  term 
sheet  signed  in  November  2008  by  such  parties  and  provides  for  the  termination  of  the  1996 
patent license agreement between us. Under the terms of the agreement, Samsung has agreed 
to  pay  us  $400.0  million  in  four  equal  installments  over  an  18-month  period  to  resolve  the 
outstanding arbitration disputes involving Samsung’s sale of 2G products, as well as the patent 
disputes  over  Samsung’s  sales  of  3G  products.  Following  our  January  30,  2009  receipt  of 
Samsung’s  first  payment,  the  parties  moved  to  end  all  litigation  and  arbitration  proceedings 
ongoing between them as more fully discussed in Item 3 of Part I of this Annual Report.

Under the terms of the 2009 Samsung PLA, we have granted Samsung a royalty-bearing license 
covering  Samsung’s  sale  of  3G  products  (including  products  built  under  both  the WCDMA  and 
cdma2000 standards and certain of their related extensions) through 2012 and a license covering 
Samsung’s sale of 2G single-mode TDMA-based products that will become paid-up in 2010.

We  will  recognize  the  revenue  associated  with  the  agreement  ratably  from  January  14,  2009 
through  the  expiration  of  the  agreement  on  December  31,  2012. The  total  amount  of  revenue 
recognized  will  include  approximately  $7.0  million  of  deferred  revenue  from  our  1996  patent 
license  agreement.  Beginning  in  first  quarter  2009,  and  in  accordance  with  our  accounting 
policies,  we  will  recognize  within  our  accounts  receivable  all  payments  due  from  Samsung 
within twelve months of our balance sheet date.

Our  2008  operating  expenses  include  a  fourth  quarter  2008  charge  of  $9.4  million  to  increase 
our  accrual  for  a  performance-based  cash  incentive  under  our  Long Term  Compensation 
Program  (LTCP)  from  the  previously  estimated  payout  of  100%  to  the  actual  payout  of  175%. 
The increase in the incentive payout was driven by the Company’s success in a number of key 
goals  including  signing  LG  Electronics,  Inc.  (“LG”)  and  Samsung,  two  of  the  top  five  cellular 
handset OEMs, to 3G licensing agreements. These licenses helped increase our share of the 3G 
market  under  license  from  approximately  20%  to  approximately  50%,  and  drove  substantial 
positive operating cash flow over the period.

SlimChip

In  October  2008,  we  announced  that,  due  to  the  rapidly  changing  landscape  of  suppliers  and 
customers  of  digital  baseband  technology,  we  were  evaluating  a  number  of  options  for  the  
modem  portion  of  our  business. These  options  could  include  an  acquisition  or  partnership  to 
achieve  the  appropriate  scale  needed  to  succeed  in  the  market,  or  the  disposition  of  the 
modem  product  portion  of  our  business  through  a  sale  or  closure. We  continue  to  evaluate 
these  options,  and  while  we  have  had  substantive  discussions  with  potential  counterparties, 
we  have  not  made  a  final  determination  of  the  most  appropriate  option  to  pursue. A  final 
decision could occur as early as the first quarter 2009. The ultimate outcome of this evaluation 
and  pursuit  of  an  option  could  result  in  an  impairment  of  long-lived  assets  related  to  the 

I N T E R D I G I TA L  2 0 0 8   A R   41

modem  business. The  assets  that  could  be  affected  include  all  or  a  significant  portion  of  our 
intangible assets, which totaled $22.7 million and $22.9 million, net of accumulated amortization, 
at  December  31,  2008  and  2007,  respectively,  and  a  significant  portion  of  our  property  and 
equipment,  which  totaled  $21.0  million  and  $24.6  million,  net  of  accumulated  depreciation,  at 
December 31, 2008 and 2007. While a disposition of the modem portion of our business could 
create  significant  long-term  cost  savings  and  improved  cash  flow,  it  could  also  produce  a 
near-term repositioning charge and a significant reduction to our technology solutions revenue, 
which contributed $12.0 million, $3.4 million and $6.9 million of revenue at December 31, 2008, 
2007 and 2006, respectively.

As  a  result  of  our  October  2008  announcement,  we  evaluated  the  carrying  value  of  our 
long-lived  assets  associated  with  the  modem  business  in  accordance  with  SFAS  No.  144. 
We concluded that there was no impairment at December 31, 2008.

Business

We  design  and  develop  advanced  digital  wireless  technologies  for  use  in  digital  cellular  and 
wireless  IEEE  802-related  products. We  actively  participate  in  and  contribute  our  technology 
solutions  to  worldwide  organizations  responsible  for  the  development  and  approval  of 
Standards  to  which  digital  cellular  and  IEEE  802-compliant  products  are  built,  and  our 
contributions  are  regularly  incorporated  into  such  Standards. We  offer  licenses  to  our  patents 
to  equipment  producers  that  manufacture,  use  and  sell  digital  cellular  and  IEEE  802-related 
products.  In  addition,  we  offer  for  license  or  sale  our  SlimChip  family  of  mobile  broadband 
modem  solutions  (which  includes  modem  IP  know-how,  baseband  ICs,  embedded  modules 
and  Reference  Platforms)  to  mobile  device  manufacturers,  semiconductor  companies  and 
other  equipment  producers  that  manufacture,  use  and  sell  digital  cellular  products. We  have 
built  our  suite  of  technology  and  patent  offerings  through  independent  development,  joint 
development with other companies and selected acquisitions.

Our  goal  is  to  derive  revenue  on  every  3G  mobile  device  sold,  either  in  the  form  of  patent 
licensing  revenues,  product  related  revenues,  or  a  combination  of  these  elements.  In  recent 
years,  our  patent  license  agreements  have  contributed  the  majority  of  our  cash  flow  and 
revenues.  Including  agreements  signed  in  first  quarter  2009,  we  now  derive  revenue  from 
approximately  one-half  of  all  3G  mobile  devices  sold  worldwide,  up  from  approximately  one-
third at the beginning of 2008.

In  2008,  2007  and  2006  our  total  revenues  were  $228.5  million,  $234.2  million  and  $480.5 
million, respectively, and our recurring revenues were $219.1 million, $219.5 million and $213.1 
million,  respectively.  Recurring  patent  licensing  revenue  made  up  at  least  95%  of  our  total 
recurring revenues in each period.

In  2008,  the  amortization  of  fixed  fee  royalty  payments  accounted  for  approximately  40%  of 
our  recurring  patent  licensing  revenues.  Due  to  the  nature  of  the  revenue  recognition,  these 
fixed  fee  revenues  are  not  affected  by  the  related  licensees’  success  in  the  market  or  the 
general  economic  climate. The  remaining  portion  of  our  recurring  patent  licensing  revenue  is 
variable in nature due to the per unit nature of the related license agreements. Approximately 
three-fourths of this per unit variable portion for 2008 related to sales of product by Japanese 
licensees for whom the majority of the sales are within Japan. As a result, our per unit variable 
patent  license  royalties  have  been,  and  will  continue  to  be,  largely  influenced  by  sales  within 
the Japanese cellular market.

We  expect  that  the  proportion  of  our  recurring  patent  licensing  revenues  resulting  from  fixed 
fee payments will increase in early 2009 upon our recognition of revenue associated with our 
new  agreement  with  Samsung.  Under  that  agreement,  effective  January  2009,  Samsung  will 
make payments totaling $400.0 million over the next 18 months.

Industry Overview

Our  future  revenues  and  cash  flows  are  dependent,  in  large  part,  on  industry-wide  sales  of 
wireless products. Over the course of the last ten years, the cellular communications industry 
has  experienced  rapid  growth  worldwide. Total  worldwide  cellular  wireless  communications 
subscriptions rose from slightly more than 320 million at the end of 1998 to approximately 4.0 
billion  at  the  end  of  2008.  In  several  countries,  mobile  telephones  now  outnumber  fixed-line 
telephones. Market analysts expect that the aggregate number of global wireless subscriptions 
could exceed 5.6 billion in 2013. In June 2008, Strategy Analytics, Inc. forecasted 1.4 billion total 
handset  sales  for  2009.  Recently,  Strategy  Analytics,  Inc.  lowered  their  forecast  for  2009 
handset  sales  by  20%. The  following  table  includes  the  recent  forecast  for  2009  and  the  June 
2008 forecast for 2010 through 2013, the latest forecast available for that period.

The growth in new cellular subscribers, combined with existing customers choosing to replace 
their  mobile  phones,  helped  fuel  the  growth  of  mobile  phone  sales  from  approximately  
168  million  units  in  1998  to  almost  1.2  billion  units  in  2008. We  believe  the  combination  of  a 
broad  subscriber  base,  continued  technological  change  and  the  growing  dependence  on  the 
Internet,  e-mail  and  other  digital  media  sets  the  stage  for  continued  growth  in  the  sales  of 
advanced  wireless  products  and  services  over  the  next  five  years. While  recent  market  forces 
and  a  global  economic  downturn  may  contribute  to  a  decline  in  total  handset  sales  for  2009, 
analysts  continue  to  predict  that  the  shift  to  advanced  3G  devices  will  continue  to  increase 
sales  in  that  category.  For  these  same  reasons,  shipments  of  3G-enabled  phones,  which 
represented approximately 25% of the market in 2007, are predicted to increase to approximately 
80% of the market by 2013. Moreover, recent advances in 3G technologies that support devices 
offering higher data rates have met with rapid consumer uptake.

In  addition  to  the  advances  in  digital  cellular  technologies,  the  industry  has  also  made 
significant advances in non-cellular wireless technologies. In particular, IEEE 802.11 WLAN has 
gained  momentum  in  recent  years  as  a  wireless  broadband  solution  in  the  home  and  office 
and  in  public  areas.  IEEE  802.11  technology  offers  high-speed  data  connectivity  through 
unlicensed  spectra  within  a  relatively  modest  operating  range.  Since  its  introduction  in  1998, 
semiconductor  shipments  of  products  built  to  the  IEEE  802.11  Standard  have  shipped  nearly  
1  billion  units  cumulatively  through  2008. Analysts  forecast  that  these  cumulative  shipments 
may reach 4 billion by 2012. In addition, the IEEE wireless Standards bodies are creating sets of 
Standards  to  enable  higher  data  rates,  provide  coverage  over  longer  distances  and  enable 
roaming. These Standards are establishing technical specifications for high data rates, such as 
IEEE 802.16 (WiMAX), as well as technology specifications to enable seamless handoff between 
different air interfaces (IEEE 802.21).

Repurchase of Common Stock

In  2006,  our  Board  of  Directors  authorized  the  repurchase  of  up  to  $350.0  million  of  our 
outstanding  common  stock  (the “2006  Repurchase  Program”).  In  October  2007,  our  Board  of 
Directors  authorized  a  $100.0  million  share  repurchase  program  (the  “2007  Repurchase 
Program”). The  Company  could  repurchase  shares  under  the  programs  through  open  market 
purchases,  pre-arranged  trading  plans  or  privately  negotiated  purchases.  During  2006,  we 
repurchased approximately 6.5 million shares of common stock for $192.4 million. At December 
31,  2006,  we  accrued  accounts  payable  of  approximately  $7.6  million  associated  with  our 
obligation to settle late December repurchases. We completed the 2006 Repurchase Program in 
first half 2007 through the repurchase of an additional 4.8 million shares of common stock for 
$157.6  million  in  2007.  Under  the  October  2007  authorization  in  2007,  we  repurchased 
approximately 1.0 million shares of common stock for $18.5 million. At December 31, 2007, we 
accrued accounts payable of approximately $0.8 million associated with our obligation to settle 
late December repurchases. During 2008, we completed the 2007 Repurchase Program through 
the repurchase of 3.8 million shares of common stock for $81.5 million.

Intellectual Property Rights Enforcement

From  time  to  time,  if  we  believe  any  party  is  required  to  license  our  patents  in  order  to 
manufacture and sell certain digital cellular products and such party has not done so, we may 
institute  legal  action  against  them. This  legal  action  typically  takes  the  form  of  a  patent 
infringement lawsuit or an administrative proceeding such as a Section 337 proceeding before 
the  U.S.  International Trade  Commission  (“USITC”).  In  addition,  we  and  our  licensees,  in  the 
normal  course  of  business,  might  seek  to  resolve  disagreements  between  the  parties  with 
respect  to  the  rights  and  obligations  of  the  parties  under  the  applicable  license  agreement 
through arbitration or litigation.

In 2008, our patent litigation and arbitration costs decreased to $34.0 million from $38.6 million 
in  2007. This  represented  58%  of  our  2008  total  patent  administration  and  licensing  costs  of 
$58.9 million. Patent litigation and administration costs will vary depending upon activity levels 
and it is likely they will continue to be a significant expense for us in the future.

Development

Our  investments  in  the  development  of  advanced  digital  wireless  technologies  and  related 
products  include  maintaining  a  highly  specialized  engineering  team  and  providing  that  team 
with  the  equipment  and  advanced  software  platforms  necessary  to  support  the  development  
of  technologies.  Over  each  of  the  last  three  years,  our  cost  of  development  has  ranged 
between 45% and 52% of our total operating expense, exclusive of non-recurring contingency 
accruals  and  repositioning  charges. The  largest  portion  of  our  cost  of  development  has  been 
personnel costs.

CRITICAL ACCOUNTING POLICIES AND ESTIMATES

Our consolidated financial statements are based on the selection and application of accounting 
principles,  generally  accepted  in  the  United  States  of  America,  which  require  us  to  make 
estimates and assumptions that affect the amounts reported in both our consolidated financial 
statements  and  the  accompanying  notes  thereto.  Future  events  and  their  effects  cannot  be 
determined  with  absolute  certainty. Therefore,  the  determination  of  estimates  requires  the 
exercise of judgment. Actual results could differ from these estimates and any such differences 
may  be  material  to  the  financial  statements.  Our  significant  accounting  policies  are  described 
in  Note  2  to  our  consolidated  financial  statements  and  are  included  in  Item  8  of  this Annual 
Report. We believe the accounting policies that are of particular importance to the portrayal of 
our  financial  condition  and  results  and  that  may  involve  a  higher  degree  of  complexity  and 
judgment in their application compared to others are those relating to patents, contingencies, 
revenue  recognition,  compensation  and  income  taxes.  If  different  assumptions  were  made  or 
different conditions had existed, our financial results could have been materially different.

Patents

We capitalize external costs, such as filing fees and associated attorney fees, incurred to obtain 
issued  patents  and  patent  license  rights. We  expense  costs  associated  with  maintaining  and 
defending  patents  subsequent  to  their  issuance. We  amortize  capitalized  patent  costs  on  a 
straight-line  basis  over  ten  years,  which  represents  the  estimated  useful  lives  of  the  patents. 
The ten year estimated useful life of internally generated patents is based on our assessment 
of such factors as the integrated nature of the portfolios being licensed, the overall makeup of 
the  portfolio  over  time  and  the  length  of  license  agreements  for  such  patents. The  estimated 
useful lives of acquired patents and patent rights, however, have and will continue to be based 
on separate analyses related to each acquisition and may differ from the estimated useful lives 
of internally generated patents. The average estimated useful life of acquired patents used thus 
far  has  been  15  years. We  assess  the  potential  impairment  to  all  capitalized  net  patent  costs 
when  events  or  changes  in  circumstances  indicate  that  the  carrying  amount  of  our  patent 
portfolio  may  not  be  recoverable. Amortization  expense  related  to  capitalized  patent  costs  
was  $11.9  million,  $9.3  million  and  $7.8  million  in  2008,  2007  and  2006,  respectively. As  of 
December  31,  2008  and  2007,  we  had  capitalized  gross  patent  costs  of  $159.7  million  and 
$132.1  million,  respectively,  which  were  offset  by  accumulated  amortization  of  $56.9  million 
and  $45.0  million,  respectively. The  weighted  average  estimated  useful  life  of  our  capitalized 
patent costs at December 31, 2008 and 2007 was 10.9 years and 11.0 years, respectively.

Contingencies

We  recognize  contingent  assets  and  liabilities  in  accordance  with  Statement  of  Financial 
Accounting Standards (SFAS) No. 5 Accounting for Contingencies. We do not include expected 
legal fees to defend ourselves in our accruals for contingent liabilities; we expense such legal 
fees in the periods in which the related services are provided.

In second quarter 2007, we recorded a $16.6 million charge to increase a $3.4 million contingent 
liability  to  $20.0  million.  Subsequently  we  have  accrued  post  judgment  interest  expense  of  
$1.8  million  ($1.1  million  during  2008)  and  reported  such  interest  expense  within  the  interest 
and  investment  income,  net,  line  within  our  Consolidated  Statements  of  Income. This 
contingency relates to an arbitration with Federal over an insurance reimbursement agreement. 
In  second  quarter  2008,  InterDigital  deposited  $23.0  million  with  the  Clerk  of  the  Court,  an 
amount  sufficient  to  secure  Federal’s  judgment  and  anticipated  interest  until  decision  by  the 
Court of Appeals.

I N T E R D I G I TA L  2 0 0 8   A R   45

In  fourth  quarter  2007,  we  accrued  $7.8  million  for  the  potential  reimbursement  of  legal  fees 
associated with our UKII matter with Nokia. During 2008, we recognized a credit of $3.9 million 
associated  with  the  reduction  of  this  accrual  in  connection  with  the  resolution  of  the  Nokia  
UK matters.

Revenue Recognition

We derive the majority of our revenue from patent licensing. The timing and amount of revenue 
recognized from each  licensee depends upon a variety of factors, including the specific terms 
of  each  agreement  and  the  nature  of  the  deliverables  and  obligations.  Such  agreements  are 
often complex and include multiple elements. These agreements can include, without limitation, 
elements  related  to  the  settlement  of  past  patent  infringement  liabilities,  up-front  and  non-
refundable  license  fees  for  the  use  of  patents  and/or  know-how,  patent  and/or  know-how 
licensing  royalties  on  covered  products  sold  by  licensees,  cross  licensing  terms  between  us 
and  other  parties,  the  compensation  structure  and  ownership  of  intellectual  property  rights 
associated  with  contractual  technology  development  arrangements,  advanced  payments  and 
fees  for  service  arrangements,  and  settlement  of  outstanding  patent  litigation.  Due  to  the 
inherent  difficulty  in  establishing  reliable,  verifiable  and  objectively  determinable  evidence  of 
the  fair  value  of  the  separate  elements  of  these  agreements,  the  total  revenue  resulting  from 
such  agreements  may  sometimes  be  recognized  over  the  performance  period.  In  other 
circumstances, such as those agreements involving consideration for past and expected future 
patent  royalty  obligations,  after  consideration  of  the  particular  facts  and  circumstances,  the 
appropriate  recording  of  revenue  between  periods  may  require  the  use  of  judgment.  In  all 
cases,  revenue  is  only  recognized  after  all  of  the  following  criteria  are  met:  (1)  written 
agreements  have  been  executed;  (2)  delivery  of  technology  or  intellectual  property  rights  has 
occurred  or  services  have  been  rendered;  (3)  fees  are  fixed  or  determinable;  and  (4) 
collectability of fees is reasonably assured.

We establish a receivable for payments expected to be received within twelve months from the 
balance  sheet  date  based  on  the  terms  in  the  license.  Our  reporting  of  such  payments  often 
results  in  an  increase  to  both  accounts  receivable  and  deferred  revenue.  Deferred  revenue 
associated  with  fixed  fee  royalty  payments  is  classified  on  the  balance  sheet  as  short-term 
when  it  is  scheduled  to  be  amortized  within  twelve  months  from  the  balance  sheet  date. All 
other  deferred  revenue  is  classified  as  long-term,  as  amounts  to  be  recognized  over  the  next 
twelve months are not known.

Patent License Agreements

Upon  signing  a  patent  license  agreement,  we  provide  the  licensee  permission  to  use  our 
patented  inventions  in  specific  applications. We  account  for  patent  license  agreements  in 
accordance  with  Emerging  Issue Task  Force  (EITF)  No.  00-21  Revenue  Arrangements  with 
Multiple  Deliverables  and  Staff Accounting  Bulletin  (SAB)  No.  104  Revenue  Recognition. We 
have  elected  to  utilize  the  leased-based  model  for  revenue  recognition,  with  revenue  being 
recognized  over  the  expected  period  of  benefit  to  the  licensee.  Under  our  patent  license 
agreements,  we  typically  receive  one  or  a  combination  of  the  following  forms  of  payment  as 
consideration  for  permitting  our  licensees  to  use  our  patented  inventions  in  their  applications 
and products:

 Consideration for Prior Sales: Consideration related to a licensee’s product sales from prior 
periods may result from a negotiated agreement with a licensee that utilized our patented 
inventions prior to signing a patent license agreement with us or from the resolution of a 
disagreement  or  arbitration  with  a  licensee  over  the  specific  terms  of  an  existing  license 
agreement. We  may  also  receive  consideration  for  prior  sales  in  connection  with  the 
settlement of patent litigation where there was no prior patent license agreement. In each 

46       I N T E R D I G I TA L  2 0 0 8   A R

 
of these cases, we record the consideration as revenue when we have obtained a signed 
agreement,  identified  a  fixed  or  determinable  price  and  determined  that  collectability  is 
reasonably assured.

 Fixed  Fee  Royalty  Payments:  Up-front,  non-refundable  royalty  payments  that  fulfill  the 
licensee’s  obligations  to  us  under  a  patent  license  agreement,  for  a  specified  time  period 
or  for  the  term  of  the  agreement. We  recognize  revenues  related  to  Fixed  Fee  Royalty 
Payments  on  a  straight-line  basis  over  the  effective  term  of  the  license. We  utilize  the 
straight-line method because we cannot reliably predict in which periods, within the term 
of a license, the licensee will benefit from the use of our patented inventions.

 Prepayments:  Up-front,  non-refundable  royalty  payments  towards  a  licensee’s  future 
obligations  to  us  related  to  its  expected  sales  of  covered  products  in  future  periods.  Our 
licensees’  obligations  to  pay  royalties  extend  beyond  the  exhaustion  of  their  Prepayment 
balance. Once a licensee exhausts its Prepayment balance, we may provide them with the 
opportunity to make another Prepayment toward future sales or it will be required to make 
Current Royalty Payments.

 Current Royalty Payments: Royalty payments covering a licensee’s obligations to us related 
to its sales of covered products in the current contractual reporting period.

Licensees that either owe us Current Royalty Payments or have Prepayment balances provide 
us with quarterly or semi-annual royalty reports that summarize their sales of covered products 
and their related royalty obligations to us. We typically receive these royalty reports subsequent 
to  the  period  in  which  our  licensees’  underlying  sales  occurred. We  recognize  revenue  in  the 
period  in  which  the  royalty  report  is  received  and  other  revenue  recognition  criteria  are  met 
due to the fact that without royalty reports from our licensees, our visibility into our licensees 
sales is very limited.

The  exhaustion  of  Prepayments  and  Current  Royalty  Payments  are  often  calculated  based  on 
related per-unit sales of covered products. From time to time, licensees will not report revenues 
in  the  proper  period,  most  often  due  to  legal  disputes;  when  this  occurs,  the  timing  and 
comparability of royalty revenue could be affected.

In cases where we receive objective, verifiable evidence that a licensee has discontinued sales 
of  products  covered  under  a  patent  license  agreement  with  us,  we  recognize  any  related 
deferred revenue balance in the period that we receive such evidence.

During 2007, we recognized revenue of $5.2 million related to unpaid patent licensee royalties. 
We based our recognition of this revenue on royalty reports received, despite the fact that the 
licensee had expressed its belief that it did not have a current payment obligation. We believed 
that we were entitled to these royalty payments and the eventual collection of these amounts 
was reasonably assured; we subsequently collected these amounts in 2008.

Technology Solutions Revenue

Technology  solutions  revenue  consists  primarily  of  revenue  from  software  licenses  and 
engineering  services.  Software  license  revenues  are  recognized  in  accordance  with  the 
American  Institute  of  Certified  Public Accountants  Statement  of  Position  (SOP)97-2  Software 
Revenue  Recognition  and  SOP  98-9 Modification  of  SOP  97-2,  Software  Revenue  Recognition. 
When  the  arrangement  with  a  customer  includes  significant  production,  modification  or 
customization  of  the  software,  we  recognize  the  related  revenue  using  the  percentage-of-
completion method in accordance with SOP 81-1 Accounting for Performance of Construction-
Type  and  Certain  Production-Type  Contracts.  Under  this  method,  revenue  and  profit  are 
recognized throughout the term of the contract, based on actual labor costs incurred to date as 
a percentage of the total estimated labor costs related to the contract. Changes in estimates for 

I N T E R D I G I TA L  2 0 0 8   A R   47

 
 
 
revenues, costs and profits are recognized in the period in which they are determinable. When 
such estimates indicate that costs will exceed future revenues and a loss on the contract exists, 
a provision for the entire loss is recognized at that time.

We recognize revenues associated with engineering service arrangements that are outside the 
scope  of  SOP  81-1  on  a  straight-line  basis  under  SAB  No.  104,  unless  evidence  suggests  that 
the  revenue  is  earned  in  a  different  pattern,  over  the  contractual  term  of  the  arrangement  or 
the  expected  period  during  which  those  specified  services  will  be  performed,  whichever  is 
longer. In such cases we often recognize revenue using proportional performance and measure 
the progress of our performance based on the relationship between incurred labor hours and 
total  estimated  labor  hours  or  other  measures  of  progress,  if  available.  Our  most  significant 
cost has been labor and we believe both labor hours and labor cost provide a measure of the 
progress of our services. The effect of changes to total estimated contract costs is recognized in 
the period such changes are determined.

When technology solutions agreements include royalty payments, we recognize revenue from 
the  royalty  payments  using  the  same  methods  described  above  under  our  policy  for 
recognizing revenue from patent license agreements.

Deferred Charges

From time-to-time, we use sales agents to assist us in our licensing activities. In such cases, we 
may  pay  a  commission. The  commission  rate  varies  from  agreement  to  agreement. 
Commissions are normally paid shortly after our receipt of cash payments associated with the 
patent license agreements. 

We  defer  recognition  of  commission  expense  related  to  both  Prepayments  and  Fixed  Fee 
Royalty Payments and amortize these expenses in proportion to our recognition of the related 
revenue.  In  2008,  2007  and  2006,  we  paid  cash  commissions  of  approximately  $0.1  million, 
$1.7 million and $18.8 million and recognized commission expense of $4.7 million, $4.7 million, 
and  $8.4  million,  respectively,  as  part  of  patent  administration  and  licensing  expense.  At 
December  31,  2008,  2007  and  2006  we  had  deferred  commission  expense  of  approximately 
$3.4  million,  $4.1  million  and  $4.1  million,  respectively,  included  within  prepaid  and  other 
current  assets  and  $4.9  million,  $8.8  million  and  $12.0  million,  respectively,  included  within 
other non-current assets.

Compensation Programs

We  use  a  variety  of  compensation  programs  to  both  attract  and  retain  employees  and  more 
closely  align  employee  compensation  with  Company  performance. These  programs  include, 
but are not limited to, an annual bonus tied to performance goals, cash awards to inventors for 
filed  patent  applications  and  patent  issuances,  restricted  stock  unit  (RSU)  awards  for  non-
managers  and  a  long-term  compensation  program  (LTCP)  for  managers  that  includes  both 
time  and  performance-based  RSUs  and  a  performance-based  cash  incentive  component. The 
LTCP is designed to have three year cycles that overlap by one year. The cycles relevant to the 
2006 — 2008 reporting period are:

•  Cash  Cycle  2a: A  long-term  performance  cash  incentive  covering  the  period  July  1,  2005 

through January 1, 2008

•  RSU Cycle 2: RSUs granted on January 1, 2005, which vest on or before January 1, 2008

•  RSU Cycle 3: RSUs granted on January 1, 2007, which vest on or before January 1, 2010

•  Cash  Cycle  3: A  long-term  performance  cash  incentive  covering  the  period  January  1,  2008 

through January 1, 2011

We recognized share-based compensation expense of $5.1 million, $9.8 million and $7.0 million 
in  2008,  2007  and  2006,  respectively. The  majority  of  the  share-based  compensation  expense, 
for all years, related to RSU awards granted to managers under our LTCP. In 2006, share-based 
compensation  expense  also  included  a  non-recurring  charge  of  $1.0  million  to  correct  our 
accounting  related  to  share-based  grants  awarded  to  two  non-employee,  non-director 
consultants in 1998. We previously accounted for these non-employee grants similarly to share-
based  employee  grants,  using  the  intrinsic  value  method. The  charge  reflects  the  incremental 
cost  that  would  have  been  recognized  by  correctly  treating  these  grants  as  non-employee 
grants  using  the  fair  value  method. We  also  recognized  $17.2  million,  $3.9  million  and  
$3.5  million  of  compensation  expense  in  2008,  2007  and  2006,  respectively,  related  to  the 
performance-based cash incentive under our LTCP. The 2008 amount includes a fourth quarter 
2008 charge of $9.4 million to increase our accrual for Cycle 2a from the previously estimated 
payout of 100% to the actual payout of 175%. The increase in the incentive payout was driven 
by  the  Company’s  success  in  achieving  a  number  of  key  goals,  including  signing  LG  and 
Samsung,  two  of  the  top  five  cellular  handset  OEMs,  to  3G  licensing  agreements. These 
licenses helped increase our share of the 3G market under license from approximately 20% to 
approximately 50%, and drove substantial positive operating cash flow over the period. Due to 
the 2008 charge to adjust the accrual rate on Cycle 2a and the structure of the different cycles 
in  the  LTCP,  we  expect  that  2009  expenses  associated  with  the  performance-based  cash 
incentive  and  RSUs  will  be  approximately  $8.1  million  less  than  2008.  However,  the  amount 
recorded  could  either  increase  or  decrease  dependent  upon  both  the  number  of  employees 
that  qualify  for  the  LTCP  and  our  future  assessment  of  the  expected  attainment  of  pre-
established performance goals.

At December 31, 2008, accrued compensation expense associated with the LTCP’s performance-
based  cash  incentive  was  based  on  an  actual  payout  of  175%  for  Cycle  2a  and  an  estimated 
payout  of  100%  for  Cash  Cycle  3.  Under  the  program,  100%  achievement  of  the  goals  set  by 
the  Compensation  Committee  of  the  Board  of  Directors  results  in  a  100%  payout  of  the 
performance-based cash incentive target amounts. For each 1% change above or below 100% 
achievement, the payout is adjusted by 2.5 percentage points with a maximum payout of 225% 
and  no  payout  for  performance  that  falls  below  80%  of  target  results. The  following  table 
provides  examples  of  the  performance-based  cash  incentive  payout  that  would  be  earned 
based on various levels of goal achievement:

Goal Achievement 

Less than 80% 

80% 

100% 

120% 

150% or greater 

Payout

0%

50%

100%

150%

225%

If we had assumed that goal achievement for Cash Cycle 3 would be either 120% or 80%, we 
would  have  accrued  either  $2.3  million  more  or  less,  respectively,  of  related  compensation 
expense through December 31, 2008. However, our estimated accrual could either increase or 
decrease  in  the  future  dependent  upon  our  future  assessment  of  the  expected  attainment 
against pre-established performance goals.

During 2006, fourteen members of our senior management voluntarily exchanged approximately 
56,000 Cycle 2 time-based RSUs for an equal number of Cycle 2 performance-based RSUs. The 
Company  ultimately  satisfied  these  performance-based  RSUs  in  early  2008  through  the 
issuance  of  approximately  11,000  shares,  based  upon  senior  management’s  performance 
against  specified  goals.  During  2006,  the  LTCP  was  amended  such  that,  beginning  with  the 

I N T E R D I G I TA L  2 0 0 8   A R   49

January  1,  2007  grant,  executives  now  receive  50%  of  their  RSU  grant  as  performance-based 
RSUs  and  50%  as  time-based.  Under  the  amendment  the  Company’s  managers  now  receive 
25% of their RSU grant as performance-based RSUs and 75% as time-based.

Under the program, 100% achievement of the goals set by the Compensation Committee of the 
Board  of  Directors  results  in  a  100%  payout  of  the  performance-based  RSU  incentive  target 
amounts.  For  each  1%  change  above  or  below  100%  achievement,  the  payout  is  adjusted  by 
4 percentage points with a maximum payout of 300%. For performance that falls below 80% of 
target, no share payout would occur. The following table provides examples of the performance-
based RSU payout that would be earned based on various levels of goal achievement:

Goal Achievement 

Less than 80% 

80% 

100% 

120% 

150% or greater 

Payout

0%

20%

100%

180%

300%

At  December  31,  2008,  we  did  not  meet  the  criteria  specified  by  SFAS  No.  123R  to  accrue 
performance-based equity compensation associated with the Cycle 3 RSU grant. If we had met 
the  criteria,  we  would  have  accrued  $2.4  million  of  related  compensation  expense  through 
December  31,  2008. We  will  establish  an  accrual  for  these  performance  RSUs  in  the  future  if 
our  future  assessment  of  the  expected  attainment  against  pre-established  performance 
goals  meets  certain  criteria  for  performance-based  share  compensation  established  by 
SFAS No. 123R.

Income Taxes

Income  taxes  are  accounted  for  under  the  asset  and  liability  method.  Under  this  method, 
deferred  tax  assets  and  liabilities  are  recognized  for  the  estimated  future  tax  consequences 
attributable to differences between the financial statement carrying amounts of existing assets 
and  liabilities  and  their  respective  tax  bases,  and  operating  loss  and  tax  credit  carryforwards. 
Deferred tax assets and liabilities are measured using enacted tax rates in effect for the year in 
which  those  temporary  differences  are  expected  to  be  recovered  or  settled. The  effect  on 
deferred  tax  assets  and  liabilities  of  a  change  in  tax  rates  is  recognized  in  the  Consolidated 
Statement of Income in the period that includes the enactment date. A valuation allowance is 
recorded to reduce the carrying amounts of deferred tax assets if management has determined 
that it is more likely than not, that such assets will not be realized.

In  addition,  the  calculation  of  tax  liabilities  involves  significant  judgment  in  estimating  the 
impact of uncertainties in the application of complex tax laws. We are subject to examinations 
by  the  Internal  Revenue  Service  (“IRS”)  and  other  taxing  jurisdictions  on  various  tax  matters, 
including  challenges  to  various  positions  we  assert  in  our  filings.  In  the  event  that  the  IRS  or 
another  taxing  jurisdiction  levies  an  assessment  in  the  future,  it  is  possible  the  assessment 
could  have  a  material  adverse  effect  on  our  consolidated  financial  condition  or  results 
of operations.

Effective  January  1,  2007  the  Company  adopted  FASB  Interpretation  No.  48,  Accounting  for 
Uncertainty  in  Income Taxes  (“FIN  48”). This  interpretation  clarifies  the  criteria  for  recognizing 
income tax benefits under FASB Statement No. 109, Accounting for Income Taxes, and requires 
additional  disclosures  about  uncertain  tax  positions.  Under  FIN  48  the  financial  statement 
recognition  of  the  benefit  for  a  tax  position  is  dependent  upon  the  benefit  being  more  likely 
than  not  to  be  sustainable  upon  audit  by  the  applicable  tax  authority.  If  this  threshold  is  met, 
the tax benefit is then measured and recognized at the largest amount that is greater than 50 
percent likely of being realized upon ultimate settlement.

50       I N T E R D I G I TA L  2 0 0 8   A R

We  adopted  FIN  48,  on  January  1,  2007. As  a  result  of  the  implementation,  we  recognized  a 
$2.1 million increase to reserves for uncertain tax positions. This increase, related to federal tax 
credits, was accounted for as a reduction to retained earnings on the balance sheet. Including 
this  cumulative  effect  adjustment,  on  January  1,  2007  we  had  $6.2  million  of  net  federal  tax 
benefits that, if recognized, would reduce our effective income tax rate in the period recognized. 
Prior  to  the  adoption  of  FIN  48,  we  accrued  for  tax  contingencies  that  have  met  both  the 
probable  and  reasonably  estimable  criteria.  In  the  event  that  the  IRS  or  another  taxing 
jurisdiction  levies  an  assessment  in  the  future,  it  is  possible  the  assessment  could  have  a 
material adverse effect on our consolidated financial condition or results of operations.

SFAS No. 157

In  September  2006,  the  Financial Accounting  Standards  Board  (“FASB”)  issued  Statement  of 
Financial Accounting  Standard  (“SFAS”)  No. 157,  Fair Value  Measurements,  which  defines  fair  
value,  establishes  a  framework  for  measuring  fair  value  in  generally  accepted  accounting 
principles and expands disclosures about fair value measurements. SFAS No. 157 does not require 
any  new  fair  value  measurements  but  provides  guidance  on  how  to  measure  fair  value  by 
providing  a  fair  value  hierarchy  used  to  classify  the  source  of  the  information.  For  financial 
assets and liabilities, SFAS No. 157 was effective for us beginning January 1, 2008. In February 
2008,  the  FASB  issued  FASB  Staff  Position  (“FSP”)  No. FAS  157-1,  Application  of  FASB  
Statement  No. 157  to  FASB  Statement  No. 13  and  Other Accounting  Pronouncements That  
Address Fair Value Measurements  for  Purposes  of  Lease  Classification  or  Measurement  under 
Statement  13  and  FSP  No. FAS  157-2,  Effective  Date  of  FASB  Statement  No. 157.  FSP  157-1 
amends SFAS No. 157 to remove certain leasing transactions from its scope. FSP 157-2 delays 
the  effective  date  of  SFAS  No. 157  to  fiscal  years  beginning  after  November  15,  2008  for  all 
non-financial  assets  and  non-financial  liabilities,  except  for  items  that  are  recognized  or 
disclosed  at  fair  value  in  the  financial  statements  on  a  recurring  basis  (at  least  annually)  and 
will be adopted by the Company beginning in the first quarter of fiscal 2009. In October 2008, 
the  FASB  issued  FSP  No. 157-3,  Determining  the  Fair Value  of  a  Financial  Asset When  the 
Market  for That Asset  is  Not Active,  to  clarify the application of SFAS 157 in inactive markets for 
financial  assets.  FSP  157-3  became  effective  upon  issuance  and  SFAS  No. 157  is  effective  for  
fiscal  years  beginning  after  November  15,  2007. The  adoption  of  SFAS  No. 157  for  financial 
assets  and  liabilities  did  not  have  an  effect  on  the  Company’s  financial  condition  or  results  
of  operations. The  Company  is  currently  evaluating  the  effect,  if  any,  of  the  adoption  of  SFAS 
No. 157  for  non-financial  assets  and  liabilities,  but  does  not  currently  believe  adoption  will  
have a material impact on the Company’s financial condition and results of operations.

SFAS No. 159

In February 2007, the FASB issued SFAS No. 159, The Fair Value Option for Financial Assets and 
Financial  Liabilities,  which  provides  companies  with  an  option  to  report  selected  financial 
assets  and  liabilities  at  fair  value  in  an  attempt  to  reduce  both  complexity  in  accounting  for 
financial  instruments  and  the  volatility  in  earnings  caused  by  measuring  related  assets  and 
liabilities  differently.  SFAS  No.  159  was  effective  for  us  beginning  January  1,  2008. The 
Company’s adoption of SFAS No. 159 on January 1, 2008 did not materially affect its financial 
position  or  results  of  operations,  as  the  Company  did  not  elect  the  option  to  report  selected 
financial assets and liabilities at fair value.

SFAS No. 141-R

In  December  2007,  the  FASB  issued  SFAS  No.  141-R,  Business  Combinations,  which  revised 
SFAS  No.  141,  Business  Combinations.  SFAS  No.  141-R  is  effective  for  us  beginning  
January  1,  2009.  Under  SFAS  No.  141,  organizations  utilized  the  announcement  date  as  the 
measurement  date  for  the  purchase  price  of  the  acquired  entity.  SFAS  No.  141-R  requires 
measurement at the date the acquirer obtains control of the acquiree, generally referred to as 
the  acquisition  date.  SFAS  No.  141-R  will  have  a  significant  impact  on  the  accounting  for 
transaction costs and restructuring costs, as well as the initial recognition of contingent assets 
and liabilities assumed during a business combination. Under SFAS No. 141-R, adjustments to 
the acquired entity’s deferred tax assets and uncertain tax position balances occurring outside 
the measurement period are recorded as a component of the income tax expense, rather than 
goodwill. The  Company  adopted  this  statement  on  January  1,  2009.  SFAS  No.  141-R’s  impact 
on  accounting  for  business  combinations  is  dependent  upon  acquisitions,  if  any,  made  on  or 
after that time.

FSP No. EITF 03-6-1

In  June  2008,  the  FASB  issued  Staff  Position  (“FSP”)  No.  EITF  03-6-1,  Determining Whether 
Instruments  Granted  in  Share-Based  Payment Transactions Are  Participating  Securities,  which 
addresses whether instruments granted in share-based payment transactions are participating 
securities  prior  to  vesting  and,  therefore,  need  to  be  included  in  earnings  allocation  in 
computing  earnings  per  share  under  the  two-class  method  as  described  in  SFAS  No.  128, 
Earnings  Per  Share.  Under  the  guidance  in  FSP  EITF  03-6-1,  unvested  share-based  payment 
awards  that  contain  non-forfeitable  rights  to  dividends  or  dividend  equivalents  (whether  paid 
or unpaid) are participating securities and shall be included in the computation of earnings per 
share pursuant to the two class method. FSP EITF 03-6-1 is effective for fiscal periods beginning 
after  December  15,  2008. All  prior-period  earnings  per  share  data  presented  shall  be  adjusted 
retrospectively.  Early  application  is  not  permitted. We  are  currently  evaluating  the  potential 
impact of the adoption of this FSP to our Consolidated Statements of Income.

legal PRoceeDIngs

We  are  routinely  involved  in  disputes  associated  with  enforcement  and  licensing  activities 
regarding  our  intellectual  property,  including  litigations  and  other  proceedings. These 
litigations  and  other  proceedings  are  important  means  to  enforce  our  intellectual  property 
rights. A January 2009 settlement of various litigations and other proceedings with Samsung 
resulted  in  a  $400.0  million  patent  license  agreement. We  are  a  party  to  other  disputes  and 
legal actions not related to our intellectual property, but also arising in the ordinary course of 
our business. Refer to Item 3 of Part I of this Annual Report for a complete description of our 
material legal proceedings.

fInancIal PosITIon, lIQUIDITY 
anD caPIT al ReQUIReMenTs

Our primary sources of liquidity are cash, cash equivalents and short-term investments, as well 
as,  cash  generated  from  operations. We  have  the  ability  to  obtain  additional  liquidity  through 
debt and equity financings but have not had a significant debt or equity financing in over ten 
years and do not anticipate a need for such financings in 2009. Based on our past performance 
and  current  expectations,  we  believe  our  available  sources  of  funds,  including  cash,  cash 
equivalents and short-term investments and cash generated from operations will be sufficient 
to  finance  our  operations,  capital  requirements  and  any  stock  repurchase  programs  that  we 
may initiate in 2009. Although our existing revenue streams have been affected by the recent 

52       I N T E R D I G I TA L  2 0 0 8   A R

global  economic  downturn,  as  more  fully  discussed  in  the “Business”  portion  of  Item  7,  our 
near  term  revenues  are  partially  insulated  from  market  swings  since  40%  of  our  recurring 
patent license revenues were based on fixed payments in 2008, and that proportion is expected 
to increase in 2009.

Cash, Cash Equivalents and Short-term Investments

At December 31, 2008 and 2007, we had the following amounts of cash, and cash equivalents 
and short-term investments (in thousands):

December 31, 

Cash and cash equivalents 

Short-term investments

$  92,018

 85,449

Total cash, cash equivalents and short-term investments 

$  141,660  

$  177,467 

Our  cash,  cash  equivalents  and  short-term  investments  decreased  $35.8  million  in  2008. 
The  decrease  was  primarily  due  to  our  repurchase  of  $82.3  million  of  our  common  stock  and 
$40.8  million  of  capital  investments  for  the  purchase  of  property,  equipment  and  technology 
licenses  and  patent  filing  costs. These  items  were  partly  offset  by  cash  from  operations  of 
$85.8 million.

We regularly review our cash and short-term investment positions. We have not identified any 
material  impairment  in  our  portfolio  of  cash,  cash  equivalents  or  short-term  investments, 
although, the overall rate of return on our portfolio has decreased along with the interest rates 
on the investments within the portfolio.

Cash Flows from Operations

We  generated  the  following  cash  flows  from  our  operating  activities  in  2008  and  2007  (in 
thousands):

December 31, 

Net cash provided by operating activities 

2008 

2007

$  85,811 

$  152,727

The  positive  operating  cash  flow  in  2008  arose  principally  from  receipts  of  approximately 
$272.1  million  related  to  2G  and  3G  patent  licensing  agreements. These  receipts  included  the 
final  $95.0  million  installment  from  LG  under  our  2006  patent  license  agreement,  current 
royalty payments of $36.6 million from Sharp Corporation of Japan (“Sharp”) and $26.6 million 
from  NEC  Corporation  of  Japan  (“NEC”)  based  on  the  royalty  reports  they  submitted  during 
the  period. We  received  prepayments,  fixed  payments  and  current  royalties  totaling  
$113.9  million  from  other  licensees. These  receipts  were  partially  offset  by  cash  operating 
expenses  (operating  expenses  less  depreciation  of  fixed  assets,  amortization  of  intangible 
assets  and  non-cash  compensation)  of  $158.0  million,  cash  payments  for  foreign  source 
withholding taxes of $16.0 million, estimated federal income tax payments of $7.2 million and 
changes in working capital during 2008.

The  positive  operating  cash  flow  in  2007  arose  principally  from  receipts  of  approximately 
$303.4 million related to 2G and 3G patent licensing agreements. These receipts included $95.0 
million  from  LG,  $41.6  million  from  Sharp,  $32.4  million  from  NEC,  $55.8  million  from  other 
licensees  that  signed  new  or  amended  patent  license  agreements  in  2007  and  $78.6  million 
from  other  existing  licensees. These  receipts  were  partially  offset  by  cash  operating  expenses 
(operating  expenses  less  depreciation  of  fixed  assets,  amortization  of  intangible  assets  and 
non-cash compensation) of $179.4 million, cash payments for foreign source withholding taxes 
of $16.1 million and changes in working capital during 2007.

Working Capital

We  believe  that  working  capital,  adjusted  to  exclude  cash,  cash  equivalents,  short-term 
investments,  current  maturities  of  debt  and  current  deferred  revenue,  provides  additional 
information  about  assets  and  liabilities  that  may  affect  our  near-term  liquidity. The  following 
table reconciles our working capital to our adjusted working capital at December 31, 2008 and 
2007 (in thousands):

$  53,078 

$  116,972

The $63.9 million decrease in adjusted working capital is primarily due to the collection of LG’s 
final installment of $95.0 million in 2008 and an increase in accrued compensation accruals of 
$22.6  million,  primarily  due  to  our  long-term  cash  incentive. These  decreases  to  adjusted 
working  capital  were  partially  offset  by  a  $31.7  million  decrease  in  account  payable, 
approximately two thirds of which related to our posting of a bond in the Federal matter (refer 
to “Federal”  within  Item  3  of  Part  I  of  this Annual  Report  for  more  information)  and  a  $15.7 
million  reduction  in  taxes  payable  associated  with  foreign  withholding  taxes  paid  upon  the 
collection of the final LG installment.

We obtained net cash from investing activities of $2.6 million in 2008 and used net cash from 
investing  activities  of  $54.3  million  in  2007. We  sold  $44.0  million  and  $12.8  million  of  short-
term marketable securities, net of purchases, in 2008 and 2007, respectively. This increase was 
driven by our respective cash needs for each period and contributed to an $8.1 million increase 
in cash and cash equivalents in 2008. Purchases of property and equipment decreased to $5.7 
million  in  2008  from  $13.8  million  in  2007  due  to  the  high  levels  of  development  tools  and 
engineering needed in 2007 to enhance our network infrastructure and systems. We also paid 
$7.0  million  and  $24.4  million  in  2008  and  2007,  respectively,  toward  technology  licenses 
necessary for our SlimChip product family. Investment costs associated with patents increased 
from  $23.9  million  in  2007  to  $28.2  million  in  2008. This  increase  reflects  higher  patent 
application activity over the past several years, combined with the lag effect between filing an 
initial  patent  application  and  the  incurrence  of  costs  to  issue  the  patent  in  both  the  U.S.  and 
foreign jurisdictions.

Net cash used in financing activities decreased $92.5 million primarily due to a $100.8 million 
decrease  in  the  amount  of  stock  we  repurchased  in  2008. We  also  received  $4.3  million  and 
$3.6  million  less  in  respective  contributions  from  option  and/or  warrant  exercises  and  tax 
benefits from share-based compensation as compared to the prior year.

Other

Our  combined  short-term  and  long-term  deferred  revenue  balance  at  December  31,  2008  was 
approximately $259.7 million, a decrease of $43.7 million from December 31, 2007. In 2008, we 
recorded  gross  increases  in  deferred  revenue  of  $84.2  million,  $64.2  million  related  to  new 
prepayments  from  new  and  existing  licensees  and  $20.0  million  related  to  an  accrued 
receivable from an existing licensee. The gross increases in deferred revenue were more than 
offset by 2008 deferred revenue recognition of $86.5 million related to the amortization of fixed 
fee  royalty  payments,  $41.4  million  related  to  per-unit  exhaustion  of  prepaid  royalties  (based 
upon royalty reports provided by our licensees) and the recognition of deferred revenue related 
to technology solutions agreements.

In  2009,  based  on current license agreements, we expect the amortization of fixed fee royalty 
payments  to  reduce  the  December  31,  2008  deferred  revenue  balance  of  $259.7  million  by 
$78.6  million. Additional  reductions  to  deferred  revenue  will  be  dependent  upon  the  level  of 
per-unit royalties our licensees report against prepaid balances.

At  December  31,  2008  and  2007,  we  had  approximately  2.9  million  options  outstanding  
that  had  exercise  prices  less  than  the  fair  market  value  of  our  stock  at  each  balance  sheet  
date. These options would have generated cash proceeds to the Company of $38.9 million and 
$33.1 million, respectively, if they had been fully exercised.

Credit Facility

Through  December  31,  2009,  we  have  a  $60  million  unsecured  revolving  credit  facility  (the 
Credit Agreement)  available  to  us. The  Credit Agreement  was  entered  into  by  the  Company, 
Bank of America, N.A., as Administrative Agent, and Citizens Bank of Pennsylvania. Borrowings 
under the Credit Agreement will, at the Company’s option, bear interest at either (i) LIBOR plus 
65  basis  points  or  (ii)  the  higher  of  the  prime  rate  or  50  basis  points  above  the  federal  funds 
rate. The  customary  restrictive  financial  and  operating  covenants  under  the  Credit Agreement 
continue in full force and effect and include, among other things, that the Company is required 
to (i) maintain certain minimum cash and short-term investment levels, (ii) maintain minimum 
financial  performance  requirements  as  measured  by  the  Company’s  income  or  loss  before 
taxes with certain adjustments, and (iii) limit or prohibit the incurrence of certain indebtedness 
and  liens,  judgments  above  a  threshold  amount  for  which  a  reserve  is  not  maintained,  and 
certain other activities outside of the ordinary course of business. Borrowings under the Credit 
Agreement can be used for general corporate purposes including capital expenditures, working 
capital,  letters  of  credit,  certain  permitted  acquisitions  and  investments,  cash  dividends  and 
stock  repurchases.  As  of  December  31,  2008,  the  Company  did  not  have  any  amounts 
outstanding under the Credit Agreement.

Contractual Obligations

We did not have any significant purchase obligations outside our ordinary course of business 
at  December  31,  2008. We  had  a  FIN  48  reserve  of  $4.4  million,  excluding  accrued  interest,  at 
December 31, 2008.

Revenues  were  $228.5  million  in  2008,  compared  to  $234.2  million  in  2007.  Recurring  patent 
licensing royalties were $207.1 million in 2008, down from $216.1 million in 2007. The decline in 
recurring  patent  licensing  royalties  was  due  to  the  absence  of  recurring  2G  revenues  from 
Sony  Ericsson,  along  with  the  softening  market  in  Japan  leading  to  decreased  royalties  from 
Sharp and NEC. These decreases were partially offset by a $14.2 million increase from all other 
new and existing licensees.

Technology  solution  revenue  increased  in  2008  to  $12.0  million  from  $3.4  million  in  2007. 
The  increase  is  primarily  attributable  to  royalties  and  license  fees  associated  with  our 
SlimChip modem IP.

In  2008,  4%  of  total  revenue,  or  $9.4  million,  was  attributable  to  non-recurring  revenue, 
primarily associated a non-refundable prepayment, made in a prior period, by a licensee who 
has exited the handset business. Of the remaining 96%, or $219.1 million, 55% was attributable 
to  companies  that  individually  accounted  for  10%  or  more  of  this  amount,  and  included  LG 
(26%),  Sharp  (17%)  and  NEC  (12%).  In  2007,  6%  of  total  revenue,  or  $14.7  million,  was 
attributable  to  non-recurring  revenue,  primarily  associated  with  prior  period  sales  of  Sony 
Ericsson’s  covered  2G  products  identified  during  a  routine  audit.  Of  the  remaining  94%,  or 
$219.5 million, 61% was attributable to companies that individually accounted for 10% or more 
of this amount, and included LG (26%), Sharp (20%) and NEC (15%).

Operating Expenses

Excluding  non-recurring  adjustments  to  arbitration  and  litigation  contingencies,  operating 
expenses  increased  from  $186.8  million  in  2007  to  $195.8  million  in  2008. The  $9.0  million 
increase was primarily due to increases/(decreases) in the following items (in millions): 

Long-term cash incentives 

Depreciation and amortization 

Personnel related costs 

Reserve for uncollectable accounts 

Insurance reimbursement 

Patent litigation and arbitration 

Share-based compensation

The increase in long-term cash incentive cost resulted from a charge of $9.4 million to increase 
our  accrual  for  Cycle  2a  of  our  LTCP  from  the  previously  estimated  payout  of  100%  to  the 
actual  payout  of  175%. The  balance  of  this  increase  and  the  decrease  in  share-based 
compensation  were  both  due  to  the  structure  of  our  LTCP  which  resulted  in  overlapping  RSU 
cycles  in  2007  and  overlapping  performance-based  cash  incentive  cycles  in  2008.  Patent 
amortization  increased  due  to  heightened  levels  of  internal  inventive  activity  in  recent  years 
resulting  in  the  expansion  of  our  patent  portfolio.  Other  depreciation  and  amortization 
increased primarily due to acquisitions of tools and technology licenses over the last two years 
associated  with  our  SlimChip  product  family.  Personnel-related  costs  increased  in  2008 
primarily due to the addition of internal resources throughout 2007 for the development of our 
SlimChip  product  family  and  annual  wage  increases. The  increase  in  the  reserve  for 
uncollectable accounts related to the establishment of a reserve against an account receivable 
associated  with  our  SlimChip  modem  IP. The  decrease  for  the  insurance  reimbursement 
includes  $7.2  million  insurance  receipts  during  2008  to  reimburse  us  for  a  portion  of  our 
defense costs in certain litigation with Nokia. This reimbursement was $5.5 million greater than 
a related reimbursement recorded in 2007. Patent litigation and arbitration expenses decreased 
primarily  due  to  the  stay  of  the  Nokia  Delaware  proceedings  which  was  issued  in  December 
2007  and  the  resolution  of  the  Nokia  UK  disputes  in  July  2008. This  decrease  was  partially 
offset  by  increased  activity  related  to  our  USITC  proceedings  against  Samsung  and  Nokia  in 
2008. The  decrease  in  patent  maintenance  costs  was  due  to  a  decline  from  the  high  level  of 
patent reviews performed in 2007.

Sales and Marketing Expense: The increase in sales and marketing expense was primarily due 
to  long-term  cash  incentives  ($1.5  million)  and  personnel  related  costs  ($0.3  million),  which 
were partially offset by a decrease in share-based compensation ($0.6 million).

General  and Administrative  Expense: The  increase  in  general  and  administrative  expense  in 
2008  was  primarily  due  to  the  reserve  for  uncollectable  accounts  ($3.0  million)  and  long-term 
cash  incentives  ($2.4  million). These  increases  were  partially  offset  by  the  decrease  in  share-
based  compensation  ($1.0  million)  and  reductions  in  the  high  levels  of  legal  and  consulting 
costs  required  to  assist  with  our  legal  entity  reorganization  and  strategic  planning  in  2007  
($1.0 million).

Patents Administration  and  Licensing  Expense:  The  decrease  in  patent  administration  and 
licensing  expense  resulted  from  the  above  noted  increases  in  insurance  reimbursement  
($5.5  million),  decreases  in  patent  litigation  and  arbitration  ($4.6  million)  and  patent 
maintenance  ($1.4  million). These  decreases  were  partially  offset  by  a  $2.6  million  increase  in 
patent amortization expense.

Development  Expense: The  increase  in  development  expense  was  due  to  increases  in  long-
term cash incentives ($8.6 million), depreciation and amortization ($4.5 million) and personnel-
related costs ($3.2 million). These increases were partially offset by the decrease in share-based 
compensation ($3.1 million).

Arbitration  and  Litigation  Contingencies:  In  2008,  we  recognized  a  non-recurring  credit  of  
$3.9  million  associated  with  the  reduction  of  a  previously  established  accrual  related  to  our 
contingent  obligation  to  reimburse  Nokia  for  a  portion  of  its  attorney’s  fees  incurred  in 
connection with the recently resolved UK matters. In 2007, we accrued non-recurring charges of 
$16.6 million and $7.8 million related to our contingent obligations to reimburse Federal under 
an  insurance  reimbursement  agreement  and  to  reimburse  Nokia  for  a  portion  of  their  legal 
fees associated with the UK II case, respectively.

Interest and Investment Income, Net

Net interest and investment income of $3.4 million in 2008 decreased $5.5 million or 62% from 
$8.9  million  in  2007. The  decrease  primarily  resulted  from  lower  rates  of  return  and  lower 
investment balances in 2008 as compared to 2007, as well as a $0.7 million write-down of our 
investment in Kineto during 2008.

Income Taxes

Our income tax provision for both 2008 and 2007 consisted of the statutory federal tax rate plus 
book-tax permanent differences related to the company’s research and development credits.

Revenues  were  $234.2  million  in  2007,  compared  to  $480.5  million  in  2006. The  decrease  was 
driven by the recognition in 2006 of $253.0 million and $12.0 million of non-recurring revenue 
related  to  the  resolution  of  patent  licensing  matters  with  Nokia  and  Panasonic,  respectively, 
and was partially offset by a $9.9 million increase in recurring patent licensing royalties in 2007. 
The increase in recurring patent license royalties was related to a new agreement with Apple, 
as  well  as  new  or  higher  contributions  from  other  existing  licensees,  including  RIM, Toshiba 
and Sharp. Together, these factors more than offset the loss of recurring 2G royalties from NEC, 
Ericsson and Sony Ericsson, which have no further 2G royalty obligations under their respective 
patent license agreements.

Technology  solution  revenue  decreased  in  2007  to  $3.4  million  from  $6.9  million  in  2006. The 
decline is primarily attributable to reduced activity under our HSDPA technology programs with 
Philips Semiconductor B.V. (Philips) and Infineon.

In  2007,  6%  of  total  revenue,  or  $14.7  million,  was  attributable  to  non-recurring  revenue, 
primarily associated with prior period sales of Sony Ericsson’s covered 2G products identified 
during  a  routine  audit.  Of  the  remaining  94%,  or  $219.5  million,  61%  was  attributable  to 
companies that individually accounted for 10% or more of this amount, and included LG (26%), 
Sharp  (20%)  and  NEC  (15%).  In  2006,  56%  of  total  revenue,  or  $267.4  million,  was  associated 
with  the  resolution  of  patient  licensing  matters,  primarily  with  Nokia  and  Panasonic.  Of  the 
remaining  44%,  or  $213.1  million,  62%  was  attributable  to  companies  that  individually 
accounted  for  10%  or  more  of  this  amount,  and  included  LG  (26%),  NEC  (19%),  and  
Sharp (17%).

Operating Expenses

Excluding  one-time  arbitration  charges  of  $16.6  million  and  $7.8  million  associated  with  our 
disputes  with  Federal  and  the  on-going  Nokia  UK  II  case,  respectively,  operating  expenses 
increased from $144.1 million in 2006 to $186.8 million in 2007. The $42.7 million increase was 
primarily due to increases/(decreases) in the following items (in millions):

Patent litigation and arbitration 

Consulting services 

Depreciation and amortization 

Personnel related costs 

Patent maintenance 

Share-based compensation 

Legal structure reorganization 

Commissions

Patent  litigation  and  arbitration  increased  primarily  due  to  our  consolidated  U.S.  International 
Trade  Commission  proceeding  against  Samsung  and  Nokia,  as  well  as  increased  activity  in 
other disputes with Nokia. Consulting services and personnel related costs increased primarily 
due to the need for additional internal and external resources to develop our SlimChip product 
family.  Patent  amortization  and  patent  maintenance  costs  both  increased  due  to  heightened 
levels  of  internal  inventive  activity  in  recent  years  resulting  in  the  expansion  of  our  patent 
portfolio.  Other  depreciation  and  amortization  increased  due  to  the  recent  acquisition  of  tools 
and  technology  licenses  to  develop  our  SlimChip  product  family. The  increase  in  share-based 
compensation expense resulted from increased LTCP costs related to the effect of overlapping 
RSU cycles in 2007 and was partly offset by a decrease resulting from a non-recurring charge

of  $1.1  million  in  third  quarter  2006  that  related  to  share-based  grants  in  1998.  Legal  and 
professional fees unrelated to patent litigation and arbitration increased due to both our 2007 
legal entity reorganization and insurance disputes. These increases in operating expenses were 
partly offset by a $3.7 million decrease in commission expense.

Sales  and  Marketing  Expense:  The  increase  in  sales  and  marketing  expense  was  due  to 
increased  travel  and  consulting  costs  ($0.5  million)  primarily  associated  with  the  advanced 
marketing of our SlimChip product family and overlapping RSU cycles ($0.6 million).

General and Administrative Expense: The increase in general and administrative expenses was 
primarily  due  to  increased  legal  and  consulting  services  primarily  associated  with  our  legal 
entity  reorganization  ($0.9  million),  personnel  costs  associated  with  wage  inflation  and 
temporary  personnel  ($0.8  million),  increased  taxes  other  than  income  ($0.6  million)  and 
overlapping RSU cycles ($0.9 million).

Patents Administration  and  Licensing  Expense: The  increase  in  patent  administration  and 
licensing expenses resulted from the above noted increases in patent litigation and arbitration 
($15.4  million),  patent  maintenance  ($3.1  million),  patent  amortization  expense  ($1.5  million), 
personnel  related  costs  ($0.8  million)  and  overlapping  RSU  cycles  ($0.4  million). These 
increases  were  offset,  in  part,  by  the  above  noted  decrease  in  commission  expense  ($3.7 
million) and the 2006 non-recurring charge related to share-based grants in 1998 ($1.0 million).

Development Expense: The increase in development expense was primarily attributable to the 
development  of  our  SlimChip  product  family,  including  increased  consulting  services  ($8.4 
million),  depreciation  and  amortization  of  development  tools  and  technology  licenses  ($5.7 
million), personnel costs ($3.7 million) and overlapping RSU cycles ($2.5 million).

Arbitration  and  Litigation  Contingencies:  In  2007,  we  accrued  non-recurring  charges  of  $16.6 
million  and  $7.8  million  related  to  our  contingent  obligations  to  reimburse  Federal  under  an 
insurance  reimbursement  agreement  and  to  reimburse  Nokia  for  a  portion  of  their  legal  fees 
associated with the UK II case, respectively.

Interest and Investment Income, Net

Net interest and investment income of $8.9 million in 2007 decreased $4.2 million or 32% from 
$13.2 million in 2006. The decrease primarily resulted from lower investment balances in 2007 
due to the completion of our share repurchase program and post judgment interest expense of 
$0.7 million which we accrued related to the Federal Arbitration Award.

Income Taxes

Our  2007  income  tax  provision  consisted  of  the  statutory  federal  tax  rate  plus  book-tax 
permanent  differences  related  to  the  company’s  research  and  development  credits.  Our  2006 
income  tax  provision  consisted  of  the  statutory  federal  tax  rate  plus  book  tax  permanent 
differences and $2.2 million of non U.S. withholding taxes.

Expected Trends

In  first  quarter  2009,  we  expect  to  report  recurring  revenues  from  existing  agreements  in  the 
range of $69.0 million to $71.0 million. The expected increase of nearly $20.0 million over fourth 
quarter  2008  levels  reflects  the  recognition  of  2-1/2  months  of  revenue  under  a  new  patent 
license  agreement  signed  in  January  2009,  partly  offset  by  the  loss  of  $1.1  million  of  fixed 
revenue  amortization  from  a  customer  who  exited  the  handset  business. This  range  does  not 
include any potential impact from additional new agreements that may be signed during first 
quarter 2009 or additional royalties identified in audits regularly conducted by us.

as  “expect,”  “will,”  “believe,”  “could,”  “would,”  “should,”  “if,”  “may,”  “might,”  “anticipate,” 
“unlikely  that,” “our  strategy,” “future,” “target,” “goal,” “trend,” “seek  to,” “seeking,” “will 
continue,”  “outcome,”  “predict,”  “estimate,”  “likely,”  “in  the  event”  or  similar  expressions 
contained  herein  are  intended  to  identify  such  forward-looking  statements. Although  forward-
looking statements in this Annual Report reflect the good faith judgment of our management, 
such  statements  can  only  be  based  on  facts  and  factors  currently  known  by  us. These 
statements reflect, among other things, our current beliefs, plans and expectations as to:

(i)  

 Our  strategy  for  achieving  our  goal  of  deriving  revenue  from  every  3G  mobile  device 
sold, including the strategic direction of the modem portion of our business.

(ii)   Our belief that:

(a)  a  number  of  our  patented  inventions  are  or  might  be  essential,  or  might  become 
essential, to products built to 2G and 3G cellular Standards and other Standards such 
as  IEEE  802  and  that  companies  making,  using  or  selling  products  compliant  with 
these Standards are required to take a license under our essential patents;

(b) our patent enforcement costs could continue to be a significant expense for us;

(c)  if  a  party  successfully  asserted  that  some  of  our  patents  are  not  valid,  should  be 
revoked,  do  not  cover  their  products  or  are  not  infringed,  there  would  not  be  any 
material  adverse  impact  on  our  ongoing  revenues  under  existing  patent  license 
agreements,  but  there  could  be  an  impact  on  our  ability  to  generate  new  royalty 
streams; and

(d)  the  loss  of  revenues  or  cash  payments  from  our  licensees  generating  revenues 
exceeding  10%  of  our  total  revenues  would  adversely  affect  either  our  cash  flow  or 
results  of  operations  and  could  affect  our  ability  to  achieve  or  sustain  acceptable 
levels of profitability.

(iii)  

 The  anticipated  proliferation  of  converged  devices  and  growth  in  global  wireless 
subscriptions.

(iv)  

 Factors  driving  the  continued  growth  of  wireless  product  and  services  sales  over  the 
next five years.

(v)  

 The  types  of  licensing  arrangements  and  various  royalty  structure  models  that  we 
anticipate  using  under  our  future  license  agreements,  including  the  impact  of  current 
trends  in  the  industry  that  could  result  in  reductions  in  and/or  caps  on  royalty  rates 
under new license agreements.

(vi)  

 The  possible  outcome  of  audits  of  our  license  agreements  when  underreporting  or 
underpayment is revealed.

I N T E R D I G I TA L  2 0 0 8   A R   61

 
   
   
   
(vii)    The timing, outcome and/or impact of our various litigation, arbitration or administrative 
proceedings  with  respect  to  our  costs,  future  license  agreements  and  accounting 
recognition.

(viii)    The impact of potential domestic patent legislation, USPTO rule changes and international 

patent rule changes on our patent prosecution and licensing strategies.

(ix)  

 Our  competition  and  factors  necessary  for  us  to  remain  successful  in  light  of  such 
competition.

(x)  

 Our  expectation  that  the  proportion  of  our  recurring  patent  licensing  revenues  resulting 
from  fixed  fee  payments  will  increase  in  early  2009  due  to  the  inception  of  revenue 
recognition associated with our new agreement with Samsung.

(xi)  

 Our  belief  that  we  will  not  need  to  obtain  additional  liquidity  through  debt  and  equity 
financings in 2009.

(xii)    Our decision with respect to the future of our modem business, which could result in an 

impairment of assets related to the modem business.

(xiii)    Our belief that a disposition of our modem business would result in significant long-term 

cost savings.

Consequently,  forward-looking  statements  concerning  our  business,  results  of  operations  and 
financial  condition  are  inherently  subject  to  risks  and  uncertainties. We  caution  readers  that 
actual  results  and  outcomes  could  differ  materially  from  those  expressed  in  or  anticipated  by 
such  forward-looking  statements. You  should  carefully  consider  the  risks  and  uncertainties 
outlined  in  greater  detail  in  this  Annual  Report,  including  Item  1A,  before  making  any 
investment decision with respect to our common stock. You should not place undue reliance on 
these  forward-looking  statements,  which  are  only  as  of  the  date  of  this Annual  Report. We 
undertake  no  obligation  to  revise  or  update  publicly  any  forward-looking  statement  for  any

investment policy guidelines. This policy also limits our amount of credit exposure to any one 
issue,  issuer  and  type  of  instrument. We  do  not  expect  any  material  loss  with  respect  to  our 
investment portfolio.

Report of Independent Registered Public Accounting Firm

To the Board of Directors and Shareholders of InterDigital, Inc.:

In our opinion, the consolidated financial statements listed in the accompanying index present 
fairly,  in  all  material  respects,  the  financial  position  of  InterDigital,  Inc.  and  its  subsidiaries  at 
December 31, 2008 and 2007, and the results of their operations and their cash flows for each 
of  the  three  years  in  the  period  ended  December  31,  2008  in  conformity  with  accounting 
principles  generally  accepted  in  the  United  States  of America.  In  addition,  in  our  opinion,  the 
financial  statement  schedule  listed  in  the  accompanying  index  presents  fairly,  in  all  material 
respects,  the  information  set  forth  therein  when  read  in  conjunction  with  the  related 
consolidated financial statements. Also in our opinion, the Company maintained, in all material 
respects, effective internal control over financial reporting as of December 31, 2008, based on 
criteria  established  in  Internal  Control  —  Integrated  Framework  issued  by  the  Committee  of 
Sponsoring  Organizations  of  the Treadway  Commission  (COSO). The  Company’s  management 
is responsible for these financial statements and financial statement schedule, for maintaining 
effective internal control over financial reporting and for its assessment of the effectiveness of 
internal control over financial reporting, included in “Management’s Annual Report on Internal 
Control  Over  Financial  Reporting”  appearing  under  Item  9A.  Our  responsibility  is  to  express 
opinions  on  these  financial  statements,  on  the  financial  statement  schedule,  and  on  the 
Company’s  internal  control  over  financial  reporting  based  on  our  integrated  audits. We 
conducted  our  audits  in  accordance  with  the  standards  of  the  Public  Company Accounting 
Oversight Board (United States). Those standards require that we plan and perform the audits 
to  obtain  reasonable  assurance  about  whether  the  financial  statements  are  free  of  material 
misstatement and whether effective internal control over financial reporting was maintained in 
all material respects. Our audits of the financial statements included examining, on a test basis, 
evidence  supporting  the  amounts  and  disclosures  in  the  financial  statements,  assessing  the 
accounting principles used and significant estimates made by management, and evaluating the 
overall  financial  statement  presentation.  Our  audit  of  internal  control  over  financial  reporting 
included obtaining an understanding of internal control over financial reporting, assessing the 
risk  that  a  material  weakness  exists,  and  testing  and  evaluating  the  design  and  operating 
effectiveness  of  internal  control  based  on  the  assessed  risk.  Our  audits  also  included 
performing  such  other  procedures  as  we  considered  necessary  in  the  circumstances. We 
believe that our audits provide a reasonable basis for our opinions.

As  discussed  in  Note  2  to  the  consolidated  financial  statements,  the  Company  changed  the 
manner in which it accounts for uncertain tax positions in 2007.

64       I N T E R D I G I TA L  2 0 0 8   A R

A  company’s  internal  control  over  financial  reporting  is  a  process  designed  to  provide 
reasonable  assurance  regarding  the  reliability  of  financial  reporting  and  the  preparation  of 
financial  statements  for  external  purposes  in  accordance  with  generally  accepted  accounting 
principles. A  company’s  internal  control  over  financial  reporting  includes  those  policies  and 
procedures that (i) pertain to the maintenance of records that, in reasonable detail, accurately 
and  fairly  reflect  the  transactions  and  dispositions  of  the  assets  of  the  company;  (ii)  provide 
reasonable  assurance  that  transactions  are  recorded  as  necessary  to  permit  preparation  of 
financial  statements  in  accordance  with  generally  accepted  accounting  principles,  and  that 
receipts  and  expenditures  of  the  company  are  being  made  only  in  accordance 
with  authorizations  of  management  and  directors  of  the  company;  and  (iii)  provide 
reasonable  assurance  regarding  prevention  or  timely  detection  of  unauthorized  acquisition, 
use,  or  disposition  of  the  company’s  assets  that  could  have  a  material  effect  on  the  
financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or 
detect misstatements. Also, projections of any evaluation of effectiveness to future periods are 
subject to the risk that controls may become inadequate because of changes in conditions, or 
that the degree of compliance with the policies or procedures may deteriorate.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

InterDigital, Inc. and Subsidiaries

DECEMBER 31, 2008

1.  bacKgR oUnD

InterDigital,  Inc.  (collectively  with  its  subsidiaries  referred  to  as “InterDigital,”  the “Company,” 
“we,” “us”  and “our”)  designs  and  develops  advanced  digital  wireless  technology  solutions. 
We are developing technologies that may be utilized to extend the life of the current generation 
of  products,  may  be  applicable  to  multiple  generational  standards  such  as  2G,  2.5G  and  3G 
cellular  standards,  as  well  as  IEEE  802  wireless  standards,  and  may  have  applicability  across 
multiple  air  interfaces.  In  conjunction  with  our  technology  development,  we  have  assembled 
an  extensive  body  of  technical  know-how,  related  intangible  products  and  a  broad  patent 
portfolio. We offer our products and solutions for license or sale to semiconductor companies 
and producers of wireless equipment and components.

Legal Entity Reorganization

On July 2, 2007, for the purpose of reorganizing into a holding Company structure, InterDigital 
Communications Corporation executed a Plan of Reorganization and an Agreement and Plan of 
Merger  (“Merger”)  with  InterDigital,  Inc.,  a  newly  formed  Pennsylvania  corporation  and 
another newly formed Pennsylvania corporation owned 100% by InterDigital, Inc. As a result of 
the  Merger,  InterDigital  Communications  Corporation  became  a  wholly-owned  subsidiary  of 
InterDigital,  Inc. These  transactions  are  herein  referred  to  collectively  as  the “Reorganization.” 
As  a  result  of  the  Reorganization,  neither  the  business  conducted  by  InterDigital,  Inc.  and 
InterDigital  Communications  Corporation  in  the  aggregate,  nor  the  consolidated  assets  and 
liabilities  of  InterDigital,  Inc.  and  InterDigital  Communications  Corporation,  in  the  aggregate, 
has changed.

By  virtue  of  the  Merger,  each  share  of  InterDigital  Communications  Corporation’s  outstanding 
common stock has been converted, on a share-for-share basis, into a share of common stock of 
InterDigital, Inc. As a result, each shareholder of InterDigital Communications Corporation has 
become the owner of an identical number of shares of common stock of InterDigital, Inc.

Further,  each  outstanding  stock  option  and  restricted  stock  unit  (“RSU”)  with  respect  to  the 
acquisition  of  shares  of  InterDigital  Communications  Corporation’s  common  stock  now 
represents  a  stock  option  or  RSU,  as  the  case  may  be,  with  respect  to  the  acquisition  of  an 
identical  number  of  shares  of  InterDigital,  Inc.’s  common  stock,  upon  the  same  terms  and 
conditions as the original stock option or RSU.

Immediately following the Merger, the provisions of the articles of incorporation and bylaws of 
InterDigital,  Inc.  were  the  same  as  those  of  InterDigital  Communications  Corporation  prior  to 
the Merger. Immediately following the Merger, the authorized capital stock of InterDigital, Inc., 
the  designations,  rights,  powers  and  preferences  of  such  capital  stock  and  the  qualifications, 
limitations  and  restrictions  thereof  were  also  the  same  as  the  capital  stock  of  InterDigital 
Communications  Corporation  immediately  prior  to  the  Merger.  Immediately  following  the 
Merger, the directors and executive officers of InterDigital, Inc., were the same individuals who 
were directors and executive officers, respectively, of InterDigital Communications Corporation 
immediately prior to the Merger.

2.  sUM MaRY  of  sIgnIfIca nT  acc oUnTIng  PolIcIes

Principles of Consolidation

The  consolidated  financial  statements  include  the  accounts  of  the  Company  and  its  wholly-
owned  subsidiaries.  All  significant  intercompany  accounts  and  transactions  have  been 
eliminated in consolidation.

Use of Estimates

The  preparation  of  financial  statements  in  conformity  with  generally  accepted  accounting 
principles  requires  management  to  make  estimates  and  assumptions  that  affect  the  reported 
amounts  of  assets  and  liabilities,  the  disclosure  of  contingent  assets  and  liabilities  as  of  the 
date  of  the  financial  statements  and  the  reported  amounts  of  revenues  and  expenses  during 
the reporting period. Actual results could differ from these estimates. We believe the accounting 
policies that are of particular importance to the portrayal of our financial condition and results, 
and  that  may  involve  a  higher  degree  of  complexity  and  judgment  in  their  application 
compared  to  others,  are  those  relating  to  patents,  contingencies,  revenue  recognition, 
compensation,  and  income  taxes.  If  different  assumptions  were  made  or  different  conditions 
had existed, our financial results could have been materially different.

Cash, Cash Equivalents and Short-Term Investments

We consider all highly liquid investments purchased with initial maturities of three months or 
less  to  be  cash  equivalents.  Management  determines  the  appropriate  classification  of  our 
investments  at  the  time  of  acquisition  and  re-evaluates  such  determination  at  each  balance 
sheet date. At December 31, 2008 and 2007, all of our short-term investments were classified as 
available-for-sale  and  carried  at  fair  value. We  determine  the  cost  of  securities  by  specific 
identification  and  report  unrealized  gains  and  losses  on  our  available-for-sale  securities  as  
a  separate  component  of  equity.  Net  unrealized  gains  on  short-term  investments  were  
$0.2 million at December 31, 2008 and 2007. Realized gains and losses for 2008, 2007 and 2006 
were as follows (in thousands):

term investments had contractual maturities within two to four years.

Fair Value of Financial Assets

Effective  January  1,  2008,  we  adopted  the  provisions  of  SFAS  No.  157  that  relate  to  our 
financial assets and financial liabilities. SFAS No. 157 establishes a hierarchy that prioritizes fair 
value  measurements  based  on  the  types  of  inputs  used  for  the  various  valuation  techniques 
(market  approach,  income  approach  and  cost  approach). The  levels  of  the  hierarchy  are 
described below:

Property and Equipment

Property  and  equipment  are  stated  at  cost.  Depreciation  and  amortization  of  property  and 
equipment are provided using the straight-line method. The estimated useful lives for computer 
equipment,  computer  software,  machinery  and  equipment,  and  furniture  and  fixtures  are 
generally  three  to  five  years.  Leasehold  improvements  are  being  amortized  over  the  lesser  of 
their  estimated  useful  lives  or  their  respective  lease  terms,  which  are  generally  five  to  ten 
years.  Buildings  are  being  depreciated  over  twenty-five  years.  Expenditures  for  major

improvements  and  betterments  are  capitalized  while  minor  repairs  and  maintenance  are 
charged to expense as incurred. Leases meeting certain capital lease criteria are capitalized and 
the  net  present  value  of  the  related  lease  payments  is  recorded  as  a  liability. Amortization  of 
capital  leased  assets  is  recorded  using  the  straight-line  method  over  the  shorter  of  the 
estimated useful lives or the lease terms.

Upon  the  retirement  or  disposition  of  property,  plant  and  equipment,  the  related  cost  and 
accumulated depreciation or amortization are removed, and a gain or loss is recorded.

Internal-Use Software Costs

Under  the  provisions  of  the  American  Institute  of  Certified  Public  Accountants  (AICPA) 
Statement of Position (SOP) 98-1 Accounting for the Costs of Computer Software Developed or 
Obtained  for  Internal-Use,  we  capitalize  costs  associated  with  software  for  internal-use. All 
computer  software  costs  capitalized  to  date  relate  to  the  purchase,  development  and 
implementation of engineering, accounting and other enterprise software. Capitalization begins 
when  the  preliminary  project  stage  is  complete  and  ceases  when  the  project  is  substantially 
complete and ready for its intended purpose. Capitalized computer software costs are amortized 
over their estimated useful life of three years.

Investments in Other Entities

We  may  make  strategic  investments  in  companies  that  have  developed  or  are  developing 
technologies  that  are  complementary  to  our  patent  licensing  or  product  strategy.  During  first 
quarter  2007,  we  made  a  $5.0  million  investment  for  a  non-controlling  interest  in  Kineto 
Wireless (“Kineto”). In first quarter 2008, we wrote-down this investment $0.7 million based on 
a lower valuation of Kineto by its investors. Early in second quarter 2008, we participated in a 
new  round  of  financing  that  included  several  other  investors,  investing  an  additional  $0.7 
million  in  Kineto. This  second  investment  both  maintained  our  ownership  position  and 
preserved certain liquidation preferences. We do not have significant influence over Kineto and 
are  accounting  for  this  investment  using  the  cost  method  of  accounting.  Under  the  cost 
method, we will not adjust our investment balance when the investee reports profit or loss but 
will  monitor  the  investment  for  an  other-than-temporary  decline  in  value. When  assessing 
whether  an  other-than-temporary  decline  in  value  has  occurred,  we  will  consider  such  factors 
as the valuation placed on the investee in subsequent rounds of financing, the performance of 
the  investee  relative  to  its  own  performance  targets  and  business  plan,  and  the  investee’s 
revenue and cost trends, liquidity and cash position, including its cash burn rate, and updated 
forecasts.

Patents

We capitalize external costs, such as filing fees and associated attorney fees, incurred to obtain 
issued  patents  and  patent  license  rights. We  expense  costs  associated  with  maintaining  and 
defending  patents  subsequent  to  their  issuance. We  amortize  capitalized  patent  costs  on  a 
straight-line  basis  over  ten  years,  which  represents  the  estimated  useful  lives  of  the  patents. 
The ten year estimated useful life of internally generated patents is based on our assessment 
of such factors as the integrated nature of the portfolios being licensed, the overall makeup of 
the  portfolio  over  time  and  the  length  of  license  agreements  for  such  patents. The  estimated 
useful lives of acquired patents and patent rights, however, have and will continue to be based 
on separate analyses related to each acquisition and may differ from the estimated useful lives 
of internally generated patents. The average estimated useful life of acquired patents used thus 
far  has  been  15  years. We  assess  the  potential  impairment  to  all  capitalized  net  patent  costs 
when  events  or  changes  in  circumstances  indicate  that  the  carrying  amount  of  our  patent 
portfolio may not be recoverable. Amortization expense related to capitalized patent costs was 
$11.9 million, $9.3 million and $7.8 million in 2008, 2007 and 2006, respectively. As of December 

I N T E R D I G I TA L  2 0 0 8   A R   73

31, 2008 and 2007, we had capitalized gross patent costs of $159.7 million and $132.1 million, 
respectively, which were offset by accumulated amortization of $56.9 million and $45.0 million, 
respectively. The  weighted  average  estimated  useful  life  of  our  capitalized  patent  costs  at 
December 31, 2008 and 2007 was 10.9 years and 11.0 years, respectively.

The estimated aggregate amortization expense related to our patents balance as of December 
31, 2008 is as follows (in thousands):

Intangible Assets

We capitalize the cost of technology solutions and platforms we acquire or license from third 
parties when they have a future benefit and the development of these solutions and platforms 
is substantially complete at the time they are acquired or licensed.
These  technologies  are  being  amortized  over  a  period  of  five  years  and  are  presented  net  of 
accumulated  amortization  of  $11.7  million  and  $4.6  million  at  December  31,  2008  and  2007, 
respectively.  Our  amortization  expense  related  to  these  technologies  was  $7.1  million,  $3.7 
million and $0.9 million in 2008, 2007 and 2006, respectively.

Contingencies

We  recognize  contingent  assets  and  liabilities  in  accordance  with  Statement  of  Financial 
Accounting Standards (SFAS) No. 5 Accounting for Contingencies. We do not include expected 
legal  fees  to  defend  ourselves  in  our  accruals  for  contingent  liabilities,  as  we  expense  legal 
fees in the periods in which the legal services are provided.

In second quarter 2007, we recorded a $16.6 million charge to increase a $3.4 million contingent 
liability to $20.0 million. Subsequently we have accrued post judgment interest expense of $1.8 
million  ($1.1  million  during  2008)  and  reported  such  interest  expense  within  the  interest  and 
investment income, net, line within our Consolidated Statements of Income. This accrual relates 
to an arbitration with Federal over an insurance reimbursement agreement. In second quarter 
2008,  InterDigital  deposited  $23.0  million  with  the  Clerk  of  the  Court,  an  amount  sufficient  to 
secure Federal’s judgment and anticipated interest until decision by the Court of Appeals.

In  fourth  quarter  2007,  we  accrued  $7.8  million  for  the  potential  reimbursement  of  legal  fees 
associated with our UKII matter with Nokia. During 2008, we recognized a credit of $3.9 million 
associated  with  the  reduction  of  this  accrual  in  connection  with  the  resolution  of  the  Nokia  
UK matters.

Revenue Recognition

We derive the majority of our revenue from patent licensing. The timing and amount of revenue 
recognized from each  licensee depends upon a variety of factors, including the specific terms 
of each agreement and the nature of the deliverables and obligations. Such agreements are 

74       I N T E R D I G I TA L  2 0 0 8   A R

 
 
 
 
 
often complex and include multiple elements. These agreements can include, without limitation, 
elements  related  to  the  settlement  of  past  patent  infringement  liabilities,  up-front  and  non-
refundable  license  fees  for  the  use  of  patents  and/or  know-how,  patent  and/or  know-how 
licensing  royalties  on  covered  products  sold  by  licensees,  cross  licensing  terms  between  us 
and  other  parties,  the  compensation  structure  and  ownership  of  intellectual  property  rights 
associated  with  contractual  technology  development  arrangements,  advanced  payments  and 
fees  for  service  arrangements,  and  settlement  of  outstanding  patent  litigation.  Due  to  the 
inherent  difficulty  in  establishing  reliable,  verifiable  and  objectively  determinable  evidence  of 
the  fair  value  of  the  separate  elements  of  these  agreements,  the  total  revenue  resulting  from 
such  agreements  may  sometimes  be  recognized  over  the  performance  period.  In  other 
circumstances, such as those agreements involving consideration for past and expected future 
patent  royalty  obligations,  after  consideration  of  the  particular  facts  and  circumstances,  the 
appropriate  recording  of  revenue  between  periods  may  require  the  use  of  judgment.  In  all 
cases,  revenue  is  only  recognized  after  all  of  the  following  criteria  are  met:  (1)  written 
agreements  have  been  executed;  (2)  delivery  of  technology  or  intellectual  property  rights  has 
occurred  or  services  have  been  rendered;  (3)  fees  are  fixed  or  determinable;  and  (4) 
collectability of fees is reasonably assured.

We establish a receivable for payments expected to be received within twelve months from the 
balance  sheet  date  based  on  the  terms  in  the  license.  Our  reporting  of  such  payments  often 
results  in  an  increase  to  both  accounts  receivable  and  deferred  revenue.  Deferred  revenue 
associated  with  fixed  fee  royalty  payments  is  classified  on  the  balance  sheet  as  short-term 
when  it  is  scheduled  to  be  amortized  within  twelve  months  from  the  balance  sheet  date. All 
other  deferred  revenue  is  classified  as  long-term,  as  amounts  to  be  recognized  over  the  next 
twelve months are not known.

Patent License Agreements

Upon  signing  a  patent  license  agreement,  we  provide  the  licensee  permission  to  use  our 
patented  inventions  in  specific  applications. We  account  for  patent  license  agreements  in 
accordance  with  Emerging  Issue Task  Force  (EITF)  No.  00-21  Revenue  Arrangements  with 
Multiple  Deliverables  and  Staff Accounting  Bulletin  (SAB)  No.  104  Revenue  Recognition. We 
have  elected  to  utilize  the  leased-based  model  for  revenue  recognition,  with  revenue  being 
recognized  over  the  expected  period  of  benefit  to  the  licensee.  Under  our  patent  license 
agreements,  we  typically  receive  one  or  a  combination  of  the  following  forms  of  payment  as 
consideration  for  permitting  our  licensees  to  use  our  patented  inventions  in  their  applications 
and products:

Consideration  for  Prior  Sales:  Consideration  related  to  a  licensee’s  product  sales  from  prior 
periods  may  result  from  a  negotiated  agreement  with  a  licensee  that  utilized  our  patented 
inventions  prior  to  signing  a  patent  license  agreement  with  us  or  from  the  resolution  of  a 
disagreement  or  arbitration  with  a  licensee  over  the  specific  terms  of  an  existing  license 
agreement. We may also receive consideration for prior sales in connection with the settlement 
of patent litigation where there was no prior patent license agreement. In each of these cases, 
we record the consideration as revenue when we have obtained a signed agreement, identified 
a fixed or determinable price and determined that collectability is reasonably assured.

Fixed  Fee  Royalty  Payments:  Up-front,  non-refundable  royalty  payments  that  fulfill  the 
licensee’s obligations to us under a patent license agreement, for a specified time period or for 
the term of the agreement. We recognize revenues related to Fixed Fee Royalty Payments on a 
straight-line  basis  over  the  effective  term  of  the  license. We  utilize  the  straight-line  method 
because we cannot reliably predict in which periods, within the term of a license, the licensee 
will benefit from the use of our patented inventions.

I N T E R D I G I TA L  2 0 0 8   A R   75

Prepayments: Up-front, non-refundable royalty payments towards a licensee’s future obligations 
to  us  related  to  its  expected  sales  of  covered  products  in  future  periods.  Our  licensees’ 
obligations to pay royalties extend beyond the exhaustion of their Prepayment balance. Once a 
licensee  exhausts  its  Prepayment  balance,  we  may  provide  them  with  the  opportunity  to 
make  another  Prepayment  toward  future  sales  or  it  will  be  required  to  make  Current 
Royalty Payments.

Current Royalty Payments: Royalty payments covering a licensee’s obligations to us related to 
its sales of covered products in the current contractual reporting period.

Licensees that either owe us Current Royalty Payments or have Prepayment balances provide 
us with quarterly or semi-annual royalty reports that summarize their sales of covered products 
and their related royalty obligations to us. We typically receive these royalty reports subsequent 
to  the  period  in  which  our  licensees’  underlying  sales  occurred. We  recognize  revenue  in  the 
period  in  which  the  royalty  report  is  received  and  other  revenue  recognition  criteria  are  met 
due to the fact that without royalty reports from our licensees, our visibility into our licensees 
sales is very limited.

The  exhaustion  of  Prepayments  and  Current  Royalty  Payments  are  often  calculated  based  on 
related per-unit sales of covered products. From time to time, licensees will not report revenues 
in  the  proper  period,  most  often  due  to  legal  disputes;  when  this  occurs,  the  timing  and 
comparability of royalty revenue could be affected.

In cases where we receive objective, verifiable evidence that a licensee has discontinued sales 
of  products  covered  under  a  patent  license  agreement  with  us,  we  recognize  any  related 
deferred revenue balance in the period that we receive such evidence.

During 2007, we recognized revenue of $5.2 million related to unpaid patent licensee royalties. 
We based our recognition of this revenue on royalty reports received, despite the fact that the 
licensee had expressed its belief that it did not have a current payment obligation. We believed 
that we were entitled to these royalty payments and the eventual collection of these amounts 
was reasonably assured; we subsequently collected these amounts in 2008.

Technology Solutions Revenue

Technology  solutions  revenue  consists  primarily  of  revenue  from  software  licenses  and 
engineering  services.  Software  license  revenues  are  recognized  in  accordance  with  the 
American  Institute  of  Certified  Public Accountants  Statement  of  Position  (SOP)  97-2  Software 
Revenue  Recognition  and  SOP  98-9 Modification  of  SOP  97-2, Software  Revenue  Recognition. 
When  the  arrangement  with  a  customer  includes  significant  production,  modification  or 
customization  of  the  software,  we  recognize  the  related  revenue  using  the  percentage-of-
completion method in accordance with SOP 81-1 Accounting for Performance of Construction-
Type  and  Certain  Production-Type  Contracts.  Under  this  method,  revenue  and  profit  are 
recognized throughout the term of the contract, based on actual labor costs incurred to date as 
a percentage of the total estimated labor costs related to the contract. Changes in estimates for 
revenues, costs and profits are recognized in the period in which they are determinable. When 
such estimates indicate that costs will exceed future revenues and a loss on the contract exists, 
a provision for the entire loss is recognized at that time.

We recognize revenues associated with engineering service arrangements that are outside the 
scope  of  SOP  81-1  on  a  straight-line  basis  under  SAB  No.  104,  unless  evidence  suggests  that 
the  revenue  is  earned  in  a  different  pattern,  over  the  contractual  term  of  the  arrangement  or 
the  expected  period  during  which  those  specified  services  will  be  performed,  whichever  is 
longer. In such cases we often recognize revenue using proportional performance and measure 
the progress of our performance based on the relationship between incurred labor hours and 
total  estimated  labor  hours  or  other  measures  of  progress,  if  available.  Our  most  significant 

76       I N T E R D I G I TA L  2 0 0 8   A R

cost has been labor and we believe both labor hours and labor cost provide a measure of the 
progress of our services. The effect of changes to total estimated contract costs is recognized in 
the period such changes are determined.

When technology solutions agreements include royalty payments, we recognize revenue from 
the  royalty  payments  using  the  same  methods  described  above  under  our  policy  for 
recognizing revenue from patent license agreements.

Deferred Charges

From time-to-time, we use sales agents to assist us in our licensing activities. In such cases, we 
may  pay  a  commission. The  commission  rate  varies  from  agreement  to  agreement. 
Commissions are normally paid shortly after our receipt of cash payments associated with the 
patent license agreements.

We  defer  recognition  of  commission  expense  related  to  both  Prepayments  and  Fixed  Fee 
Royalty Payments and amortize these expenses in proportion to our recognition of the related 
revenue.  In  2008,  2007  and  2006,  we  paid  cash  commissions  of  approximately  $0.1  million, 
$1.7 million and $18.8 million and recognized commission expense of $4.7 million, $4.7 million, 
and  $8.4  million,  respectively,  as  part  of  patent  administration  and  licensing  expense.  At 
December  31,  2008,  2007  and  2006,  we  had  deferred  commission  expense  of  approximately 
$3.4  million,  $4.1  million  and  $4.1  million,  respectively,  included  within  prepaid  and  other 
current  assets  and  $4.9  million,  $8.8  million  and  $12.0  million,  respectively,  included  within 
other non-current assets.

Research and Development

Research  and  development  expenditures  are  expensed  in  the  period  incurred,  except  certain 
software development costs which are capitalized between the point in time that technological 
feasibility  of  the  software  is  established  and  the  product  is  available  for  general  release  to 
customers. We did not have any such capitalized software costs in any period presented.

Compensation Programs

We account for the compensation cost related to share-based transactions in accordance with 
SFAS No. 123(R), which requires these costs to be recognized in the financial statements based 
on  the  fair  values  of  the  instruments  issued.  SFAS  No.  123(R)  requires  that  we  reserve  for 
estimated forfeitures of stock-based compensation awards. At December 31, 2008 and 2007, we 
have estimated the forfeiture rates for outstanding RSUs to be between 0% and 14% over their 
lives  of  one  to  three  years,  depending  upon  the  group  receiving  the  grant  and  the  specific 
terms of the award issued.

In  2006,  we  adopted  the  short-cut  method  to  establish  the  historical  additional  paid-in-capital 
pool (APIC Pool) related to the tax effects of employee share-based compensation. Any positive 
balance  would  be  available  to  absorb  tax  shortfalls  (which  occur  when  the  tax  deductions 
resulting  from  share-based  compensation  are  less  than  the  related  book  expense)  recognized 
subsequent to the adoption of SFAS No. 123(R). We did not incur any net tax shortfalls in either 
2008 or 2007.

In all periods, our policy has been to set the value of RSU and restricted stock awards equal to 
the value of our underlying common stock on the date of measurement. We amortize expense 
for all such awards using an accelerated method.

I N T E R D I G I TA L  2 0 0 8   A R   77

Concentration of Credit Risk and Fair Value of Financial Instruments

Financial instruments that potentially subject us to concentration of credit risk consist primarily 
of  cash  equivalents,  short-term  investments,  and  accounts  receivable. We  place  our  cash 
equivalents and short-term investments only in highly rated financial instruments and in United 
States Government instruments.

Our accounts receivable are derived principally from patent license agreements and technology 
solutions.  At  December  31,  2008,  four  customers  represented  59%,  17%,  10%  and  10% 
respectively,  of  our  accounts  receivable  balance.  At  December  31,  2007,  two  customers 
represented  73%  and  15%,  respectively,  of  our  accounts  receivable  balance. We  perform 
ongoing  credit  evaluations  of  our  customers  who  generally  include  large,  multi-national, 
wireless telecommunications equipment manufacturers. We believe that the book value of our 
financial instruments approximate their fair values.

Impairment of Long-Lived Assets

Pursuant to SFAS No. 144, Accounting for the Impairment or Disposal of Long-Lived Assets, we 
evaluate long-lived assets and intangible assets for impairment when factors indicate that the 
carrying  value  of  an  asset  may  not  be  recoverable. When  factors  indicate  that  such  assets 
should  be  evaluated  for  possible  impairment,  we  review  the  realizability  of  our  long-lived 
assets  by  analyzing  the  projected  undiscounted  cash  flows  in  measuring  whether  the  asset  is 
recoverable. No such adjustments were recorded in 2008, 2007 or 2006.

Income Taxes

Income  taxes  are  accounted  for  under  the  asset  and  liability  method.  Under  this  method, 
deferred  tax  assets  and  liabilities  are  recognized  for  the  estimated  future  tax  consequences 
attributable to differences between the financial statement carrying amounts of existing assets 
and  liabilities  and  their  respective  tax  bases,  and  operating  loss  and  tax  credit  carryforwards. 
Deferred tax assets and liabilities are measured using enacted tax rates in effect for the year in 
which  those  temporary  differences  are  expected  to  be  recovered  or  settled. The  effect  on 
deferred  tax  assets  and  liabilities  of  a  change  in  tax  rates  is  recognized  in  the  Consolidated 
Statement of Income in the period that includes the enactment date. A valuation allowance is 
recorded to reduce the carrying amounts of deferred tax assets if management has determined 
that it is more likely than not, that such assets will not be realized.

In  addition,  the  calculation  of  tax  liabilities  involves  significant  judgment  in  estimating  the 
impact of uncertainties in the application of complex tax laws. We are subject to examinations 
by  the  Internal  Revenue  Service  (IRS)  and  other  taxing  jurisdictions  on  various  tax  matters, 
including  challenges  to  various  positions  we  assert  in  our  filings.  In  the  event  that  the  IRS  or 
another  taxing  jurisdiction  levies  an  assessment  in  the  future,  it  is  possible  the  assessment 
could  have  a  material  adverse  effect  on  our  consolidated  financial  condition  or  results  
of operations.

Effective  January  1,  2007  the  Company  adopted  FASB  Interpretation  No.  48,  Accounting  for 
Uncertainty  in  Income Taxes  (FIN  48). This  interpretation  clarifies  the  criteria  for  recognizing 
income tax benefits under FASB Statement No. 109, Accounting for Income Taxes, and requires 
additional  disclosures  about  uncertain  tax  positions.  Under  FIN  48  the  financial  statement 
recognition  of  the  benefit  for  a  tax  position  is  dependent  upon  the  benefit  being  more  likely 
than  not  to  be  sustainable  upon  audit  by  the  applicable  tax  authority.  If  this  threshold  is  met, 
the  tax  benefit  is  then  measured  and  recognized  at  the  largest  amount  that  is  greater  than  
50 percent likely of being realized upon ultimate settlement.

78       I N T E R D I G I TA L  2 0 0 8   A R

We  adopted  FIN  48,  on  January  1,  2007. As  a  result  of  the  implementation,  we  recognized  a 
$2.1 million increase to reserves for uncertain tax positions. This increase, related to federal tax 
credits, was accounted for as a reduction to retained earnings on the balance sheet. Including 
this  cumulative  effect  adjustment,  on  January  1,  2007  we  had  $6.2  million  of  net  federal  tax 
benefits that, if recognized, would reduce our effective income tax rate in the period recognized. 
Prior  to  the  adoption  of  FIN  48,  we  accrued  for  tax  contingencies  that  have  met  both  the 
probable  and  reasonably  estimable  criteria.  In  the  event  that  the  IRS  or  another  taxing 
jurisdiction  levies  an  assessment  in  the  future,  it  is  possible  the  assessment  could  have  a 
material adverse effect on our consolidated financial condition or results of operations.

Net Income Per Common Share

Basic  earnings  per  share  (“EPS”)  is  calculated  by  dividing  net  income  available  to  common 
shareholders  by  the  weighted-average  number  of  common  shares  outstanding  for  the  period. 
Diluted EPS reflects the potential dilution that could occur if options, warrants or other securities 
with features that could result in the issuance of common stock were exercised or converted to 
common stock. The following tables reconcile the numerator and the denominator of the basic 
and diluted net income per share computation (in thousands, except for per share data):

respective periods and, therefore, their effect would have been anti-dilutive.

Recent Accounting Pronouncements

SFAS No. 157

In  September  2006,  the  Financial Accounting  Standards  Board  (“FASB”)  issued  Statement  of 
Financial Accounting  Standard  (“SFAS”)  No. 157,  Fair Value  Measurements,  which  defines  fair 
value,  establishes  a  framework  for  measuring  fair  value  in  generally  accepted  accounting 
principles  and  expands  disclosures  about  fair  value  measurements.  SFAS  No.  157  does  not 
require any new fair value measurements but provides guidance on how to measure fair value 
by providing a fair value hierarchy used to classify the source of the information. For financial 
assets  and  liabilities,  SFAS  No.  157  was  effective  for  us  beginning  January  1,  2008.  In 
February  2008,  the  FASB  issued  FASB  Staff  Position  (“FSP”)  No.  FAS  157-1,  Application  of 
FASB  Statement  No.  157  to  FASB  Statement  No.  13  and  Other Accounting  Pronouncements 
That Address  Fair Value  Measurements  for  Purposes  of  Lease  Classification  or  Measurement 
under  Statement  13  and  FSP  No.  FAS  157-2,  Effective  Date  of  FASB  Statement  No.  157.  FSP 
157-1  amends  SFAS  No.  157  to  remove  certain  leasing  transactions  from  its  scope.  FSP  157-2 
delays the effective date of SFAS No. 157 to fiscal years beginning after November 15, 2008 for 
all  non-financial  assets  and  non-financial  liabilities,  except  for  items  that  are  recognized  or 
disclosed  at  fair  value  in  the  financial  statements  on  a  recurring  basis  (at  least  annually)  and 
will be adopted by the Company beginning in the first quarter of fiscal 2009. In October 2008, 
the  FASB  issued  FSP  No.  157-3,  Determining  the  Fair Value  of  a  Financial Asset When  the 
Market for That Asset is Not Active, to clarify the application of SFAS 157 in inactive markets for 
financial  assets.  FSP  157-3  became  effective  upon  issuance  and  SFAS  No.  157  is  effective  for 
fiscal  years  beginning  after  November  15,  2007. The  adoption  of  SFAS  No.  157  for  financial 
assets  and  liabilities  did  not  have  an  effect  on  the  Company’s  financial  condition  or  results  of 
operations. The  Company  is  currently  evaluating  the  effect,  if  any,  of  the  adoption  of  SFAS 
No.  157  for  non-financial  assets  and  liabilities,  but  does  not  currently  believe  adoption  will 
have a material impact on the Company’s financial condition and results of operations.

SFAS No. 159

In February 2007, the FASB issued SFAS No. 159, The Fair Value Option for Financial Assets and 
Financial  Liabilities,  which  provides  companies  with  an  option  to  report  selected  financial 
assets  and  liabilities  at  fair  value  in  an  attempt  to  reduce  both  complexity  in  accounting  for 
financial  instruments  and  the  volatility  in  earnings  caused  by  measuring  related  assets  and 
liabilities  differently.  SFAS  No.  159  was  effective  for  us  beginning  January  1,  2008. The 
Company’s adoption of SFAS No. 159 on January 1, 2008 did not materially affect its financial 
position  or  results  of  operations,  as  the  Company  did  not  elect  the  option  to  report  selected 
financial assets and liabilities at fair value.

SFAS No. 141-R

In  December  2007,  the  FASB  issued  SFAS  No.  141-R,  Business  Combinations,  which  revised 
SFAS No. 141, Business Combinations. SFAS No. 141-R is effective for us beginning January 1, 
2009. Under SFAS No. 141, organizations utilized the announcement date as the measurement 
date for the purchase price of the acquired entity. SFAS No. 141-R requires measurement at the 
date the acquirer obtains control of the acquiree, generally referred to as the acquisition date. 
SFAS  No.  141-R  will  have  a  significant  impact  on  the  accounting  for  transaction  costs  and 
restructuring costs, as well as the initial recognition of contingent assets and liabilities assumed 
during  a  business  combination.  Under  SFAS  No.  141-R,  adjustments  to  the  acquired  entity’s 
deferred  tax  assets  and  uncertain  tax  position  balances  occurring  outside  the  measurement 
period  are  recorded  as  a  component  of  the  income  tax  expense,  rather  than  goodwill. The 
Company adopted this statement on January 1, 2009. SFAS No. 141-R’s impact on accounting 
for business combinations is dependent upon acquisitions, if any, made on or after that time.

FSP No. EITF 03-6-1

In  June  2008,  the  FASB  issued  Staff  Position  (“FSP”)  No.  EITF  03-6-1,  Determining Whether 
Instruments  Granted  in  Share-Based  Payment Transactions  are  Participating  Securities,  which 
addresses whether instruments granted in share-based payment transactions are participating 
securities  prior  to  vesting  and,  therefore,  need  to  be  included  in  earnings  allocation  in 
computing  earnings  per  share  under  the  two-class  method  as  described  in  SFAS  No.  128, 
Earnings  Per  Share.  Under  the  guidance  in  FSP  EITF  03-6-1,  unvested  share-based  payment 
awards  that  contain  non-forfeitable  rights  to  dividends  or  dividend  equivalents  (whether  paid 
or unpaid) are participating securities and shall be included in the computation of earnings per 
share pursuant to the two class method. FSP EITF 03-6-1 is effective for fiscal periods beginning 
after  December  15,  2008. All  prior-period  earnings  per  share  data  presented  shall  be  adjusted 
retrospectively.  Early  application  is  not  permitted. We  are  currently  evaluating  the  potential 
impact of the adoption of this FSP to our Consolidated Statements of Income.

We  have  one  reportable  segment. As  of  December  31,  2008,  substantially  all  of  our  revenue 
was derived from a limited number of customers based outside of the United States (primarily 
Asia and Europe). These revenues were paid in U.S. dollars and not subject to any substantial 
foreign exchange transaction risk. During 2008, 2007, and 2006, revenue from our Asian-based 
licensees  comprised  84%,  80%,  and  39%  of  total  revenues,  respectively.  For  the  same  years, 
revenue  from  our  European-based  licensees  comprised  3%,  11%,  and  59%  of  total  revenues, 
respectively.

During  2008,  2007,  and  2006,  the  following  customers  accounted  for  10%  or  more  of  total

Samsung Settlement

On  January  14,  2009,  we  entered  into  a  patent  license  agreement  (the “agreement”)  with 
Samsung Electronics Co., Ltd. (“Samsung”) covering Samsung’s affiliates, including Samsung 
Electronics America, Inc. The agreement supersedes the terms of the binding term sheet signed 
in November 2008 by such parties and provides for the termination of the 1996 patent license 
agreement  between  us.  Under  the  terms  of  the  agreement,  Samsung  has  agreed  to  pay  us 
$400.0  million  in  four  equal  installments  over  an  18-month  period  to  resolve  the  outstanding 
arbitration  disputes  involving  Samsung’s  sale  of  2G  products,  as  well  as  the  patent  disputes 
over  Samsung’s  sales  of  3G  products.  Following  our  January  30,  2009  receipt  of  Samsung’s 
first  payment,  the  parties  moved  to  end  all  litigation  and  arbitration  proceedings  ongoing 
between them as more fully discussed in the Note 8 “ LITIGATION AND LEGAL PROCEEDINGS “.

Under the terms of the agreement, we have granted Samsung a royalty-bearing license covering 
Samsung’s sale of 3G products (including products built under both the WCDMA and cdma2000 
standards and certain of their related extensions) through 2012 and a license covering Samsung’s 
sale of 2G single-mode TDMA-based products that will become paid-up in 2010.

We  will  recognize  the  revenue  associated  with  the  agreement  ratably  from  January 14,  2009 
through  the  expiration  of  the  agreement  on  December  31,  2012. The  total  amount  of  revenue 
recognized  will  include  approximately  $7.0  million  of  deferred  revenue  from  our  1996  patent 
license  agreement.  Beginning  in  first  quarter  2009  and  in  accordance  with  our  accounting 
policies,  we  will  recognize  within  our  accounts  receivable,  all  payments  due  from  Samsung 
within twelve months of our balance sheet date.

SlimChip

In  October  2008,  we  announced  that,  due  to  the  rapidly  changing  landscape  of  suppliers  and 
customers  of  digital  baseband  technology,  we  were  evaluating  a  number  of  options  for  the 
modem  portion  of  our  business. These  options  could  include  an  acquisition  or  partnership  to 
achieve  the  appropriate  scale  needed  to  succeed  in  the  market,  or  the  disposition  of  the 
modem  product  portion  of  our  business  through  a  sale  or  closure. We  continue  to  evaluate 
these  options,  and  while  we  have  had  substantive  discussions  with  potential  counterparties, 
we  have  not  made  a  final  determination  of  the  most  appropriate  option  to  pursue. A  final 
decision could occur as early as the first quarter 2009. The ultimate outcome of this evaluation 
and  pursuit  of  an  option  could  result  in  an  impairment  of  assets  related  to  the  modem 
business. The assets that could be affected include all or a significant portion of our intangible 
assets,  which  totaled  $22.7  million  and  $22.9  million,  net  of  accumulated  amortization,  at 
December  31,  2008  and  2007,  respectively,  and  a  significant  portion  of  our  property  and 
equipment,  which  totaled  $21.0  million  and  $24.6  million,  net  of  accumulated  depreciation,  at 
December 31, 2008 and 2007. While a disposition of the modem portion of our business could 
create significant long-term cost savings and improved cash flow, it could also produce a near-
term  repositioning  charge  and  a  significant  reduction  to  our  technology  solutions  revenue, 
which contributed $12.0 million, $3.4 million and $6.9 million of revenue at December 31, 2008, 
2007 and 2006.

As  a  result  of  our  October  2008  announcement,  we  evaluated  the  carrying  value  of  our  long-
lived  assets  associated  with  the  modem  business  in  accordance  with  SFAS  No.  144. We 
concluded that there was no impairment at December 31, 2008.

Technology Solution Agreements

We  account  for  portions  of  our  technology  solution  agreements  using  the  proportional 
performance  method.  During  2008,  2007  and  2006,  we  recognized  related  revenue  of 
approximately  $4.3  million,  $1.2  million  and  $4.5  million,  respectively,  using  the  proportional 
performance  method.  Our  accounts  receivable,  net  at  December  31,  2008  and  2007  included 
unbilled  amounts  of  $0.0  million  and  $0.3  million,  respectively.  During  2008,  we  billed  and 
collected all amounts that were unbilled at December 31, 2007.

In December 2005, we entered into a two-year $60.0 million unsecured revolving credit facility 
(the  Credit Agreement). The  Credit Agreement  was  entered  into  by  the  Company,  Bank  of 
America, N.A., as Administrative Agent, and Citizens Bank of Pennsylvania. On July 2, 2007, as 
a  result  of  the  Company’s  internal  corporate  reorganization,  InterDigital  Communications 
Corporation,  the  Company,  the  Subsidiary  Guarantors  party  thereto,  the  Lenders  and  Bank  of 
America,  N.A.,  as  Administrative  Agent  and  L/C  Issuer,  entered  into  a  First  Amendment, 
Consent  and  Joinder  to  Credit Agreement. We  did  not  borrow  against  the  Credit Agreement 
during the initial two year term.

In December 2007, we entered into a Second Amendment to Credit Agreement resulting in the 
continuation  of  our  two-year  $60.0  million  unsecured  revolving  credit  facility  (the  Credit 
Agreement)  through  December  2009.  Under  the  Second Amendment,  borrowings  under  the 
Credit Agreement will, at the Company’s option, bear interest at either (i) LIBOR plus 65 basis 
points  or  (ii)  the  higher  of  the  prime  rate  or  50  basis  points  above  the  federal  funds  rate.

to (i) maintain certain minimum cash and short-term investment levels, (ii) maintain minimum 
financial  performance  requirements  as  measured  by  the  Company’s  income  or  loss  before 
taxes with certain adjustments, and (iii) limit or prohibit the incurrence of certain indebtedness 
and  liens,  judgments  above  a  threshold  amount  for  which  a  reserve  is  not  maintained,  and 
certain other activities outside of the ordinary course of business. Borrowings under the Credit 
Agreement can be used for general corporate purposes including capital expenditures, working 
capital,  letters  of  credit,  certain  permitted  acquisitions  and  investments,  cash  dividends  and 
stock  repurchases.  As  of  December  31,  2008,  the  Company  did  not  have  any  amounts 
outstanding under the Credit Agreement.

During 1996, we purchased our King of Prussia, Pennsylvania facility for $3.7 million, including 
cash  of  $0.9  million  and  a  16-year  mortgage  of  $2.8  million  with  interest  payable  at  a  rate  of 
8.28% per annum.

Three  capital  software  lease  obligations  are  payable  annually,  while  all  other  capital  lease 
obligations  are  payable  in  monthly  installments. All  capital  leases  have  an  average  rate  of 
5.43%,  through  2010. The  net  book  value  of  software  &  equipment  under  capitalized  lease 
obligations was $1.9 million at December 31, 2008 and $3.0 million at December 31, 2007.

Samsung Litigation and Settlement

As  described  in  more  detail  below  InterDigital  Communications,  LLC  (“IDC”)  and  InterDigital 
Technology  Corp.  (“ITC”)  (“IDC”  and  “ITC”  collectively  referred  to  as  “InterDigital”)  and 
Samsung  Electronics  Co.,  Ltd.  (“Samsung”)  have  been  engaged  in  a  series  of  arbitration  and 
litigation proceedings concerning royalties owed for Samsung’s sales of 2G products under the 
1996  Patent  License Agreement  between  ITC  and  Samsung  (the “1996  Samsung  PLA”).  In 
addition,  as  described  in  more  detail  below,  InterDigital  and  Samsung  have  been  engaged  in 

84       I N T E R D I G I TA L  2 0 0 8   A R

 
 
 
   
 
 
litigation  since  March  2007  in  the  U.S.  International Trade  Commission  (“USITC”  or  the 
“Commission”) and in the Delaware District Court in which InterDigital alleges that Samsung’s 
sales of 3G products infringe certain InterDigital patents.

On November 24, 2008, InterDigital and Samsung entered into a binding Term Sheet (“Samsung 
Term Sheet”) to settle their 2G and 3G disputes. On January 14, 2009, InterDigital and Samsung 
entered  into  a  patent  license  agreement  (the “2009  Samsung  PLA”),  which  superseded  the 
Samsung Term  Sheet,  and  which  also  superseded,  and  provided  for  the  termination  of,  the 
1996 Samsung PLA.

Under  the  terms  of  the  2009  Samsung  PLA,  Samsung  has  agreed  to  pay  InterDigital  $400.0 
million  in  four  equal  installments  over  an  18-month  period  to  resolve  the  parties’  disputes, 
including:  (a)  the  outstanding  arbitration  disputes  and  enforcement  proceedings  involving 
Samsung’s  sale  of  2G  products  (see  “Samsung  2nd  Arbitration  and  Related  Enforcement 
Proceeding”  and  “Samsung  3rd  Arbitration”  discussed  below);  and  (b)  the  outstanding  
patent  infringement  litigation  concerning  Samsung’s  sales  of  3G  products,  including  the  
USITC Action  against Samsung and the related Delaware District Court proceeding (described 
below).  In  addition,  the  2009  Samsung  PLA  provides  for  the  dismissal  of  a  separate  
pending  action  between  the  parties  in  the  Delaware  District  Court  (see “Samsung  Delaware 
Proceeding” below).

Samsung United States International Trade Commission Proceeding and Related Delaware 
District Court Proceeding

In  March  2007,  InterDigital,  Inc.’s  wholly-owned  subsidiaries  InterDigital  Communications,  LLC 
(“IDC”)  and  InterDigital Technology  Corporation  (“ITC”)  filed  a  Complaint  against  Samsung 
Electronics Co., Ltd. and certain of its affiliates (collectively, “Samsung”) in the USITC alleging 
that  Samsung  engages  in  unfair  trade  practices  by  selling  for  importation  into  the  United 
States,  importing  into  the  United  States,  and  selling  after  importation  into  the  United  States 
certain  3G  handsets  and  components  that  infringe  three  of  InterDigital’s  patents.  In  May  2007 
and December 2007, a fourth patent and fifth patent, respectively, were added to our Complaint 
against Samsung. The Complaint sought an exclusion order barring from entry into the United 
States  infringing  3G WCDMA  handsets  and  components  that  are  imported  by  or  on  behalf  of 
Samsung. The  Complaint  also  sought  a  cease  and  desist  order  to  bar  sales  of  infringing 
Samsung products that had already been imported into the United States.

On the same date as our filing of the Samsung USITC action referenced above, we also filed a 
Complaint  in  the  United  States  District  Court  for  the  District  of  Delaware  (“Delaware  District 
Court”)  alleging  that  Samsung’s  3G WCDMA  handsets  infringe  the  same  three  InterDigital 
patents identified in the original Samsung USITC Complaint. In June 2007, the Delaware District 
Court  entered  a  Stipulated  Order  staying  this  Delaware  District  Court  proceeding  against 
Samsung  until  the  USITC’s  determination  in  this  matter  becomes  final. The  Delaware  District 
Court  permitted  InterDigital  to  add  to  the  stayed  Delaware  action  the  fourth  and  fifth  patents 
InterDigital had asserted against Samsung in the USITC action.

As  described  more  fully  below  (see “Nokia  USITC  Proceeding  and  Related  Delaware  District 
Court  and  Southern  District  of  New York  Proceedings”),  in August  2007,  we  filed  a  Complaint 
against  Nokia  Corporation  and  Nokia,  Inc.  (collectively, “Nokia”)  in  the  USITC  alleging  that 
Nokia engaged in an unfair trade practice by selling for importation, importing into the United 
States, and selling after importation certain 3G mobile handsets and components that infringe 
two  of  InterDigital’s  patents.  On  October  24,  2007,  the Administrative  Law  Judge  overseeing  
the  two  USITC  proceedings  against  Samsung  and  Nokia,  respectively,  issued  an  Order 
consolidating  the  investigations  pending  against  Samsung  and  Nokia.  On  May  16,  2008,  the 
Administrative  Law  Judge  deconsolidated  the  investigations  against  Samsung  and  Nokia  and 

I N T E R D I G I TA L  2 0 0 8   A R   85

set an evidentiary hearing date in the investigation against Samsung to begin on July 8, 2008. 
On  May  22,  2008,  the  Administrative  Law  Judge  reset  the Target  Date  for  the  USITC’s  
Final  Determination  in  the  Samsung  investigation  (337-TA-601)  to  March  25,  2009,  requiring  a 
final  Initial  Determination  by  the  Administrative  Law  Judge  to  be  entered  no  later  than 
November 25, 2008.

On  June  24,  2008,  the  Administrative  Law  Judge  entered  summary  determination  in  the 
Samsung  investigation  (337-TA-601)  on  InterDigital’s  motion  that  InterDigital  has  satisfied  the 
domestic industry requirement based on its licensing activities. Samsung requested review of 
this  decision  by  the  full  Commission.  On  July  25,  2008,  the  full  Commission  issued  a  notice 
that it would not review the Administrative Law Judge’s Initial Determination that a licensing-
based domestic industry exists. As a result, the Administrative Law Judge’s Initial Determination 
of this issue has become the decision of the full Commission.

The  evidentiary  hearing  in  the  Samsung  investigation  commenced  on  July  8,  2008  and 
concluded on July 15, 2008.

Following the evidentiary hearing and the post-hearing filings, the Initial Determination of the 
Administrative  Law  Judge  was  expected  by  November  25,  2008  and  the Target  Date  for  the 
Final  Determination  of  the  USITC  was  expected  by  March  25,  2009,  but  these  dates  were 
modified. As referenced above, on November 24, 2008, InterDigital and Samsung entered into 
the  Samsung Term  Sheet.  Pursuant  to  the  Samsung Term  Sheet,  on  November  24,  2008,  the 
parties  jointly  filed  a  motion  with  the  USITC  in  the  Samsung  investigation  (337-TA-601) 
requesting  an  immediate  stay  of  the  procedural  schedule  and  seeking  to  reset  the  Initial 
Determination  date  to  February  9,  2009,  or  as  soon  thereafter  as  it  may  be  scheduled,  and  to 
reset  the Target  Date  for  the  Final  Determination  to  June  9,  2009,  or  as  soon  thereafter  as  
it  may  be  scheduled.  On  November  24,  2008,  the  Administrative  Law  Judge  issued  an  
Initial  Determination  staying  the  current  procedural  schedule  and  resetting  the  Initial 
Determination date to February 9, 2009 and resetting the Target Date for the Final Determination 
to June 9, 2009. On December 9, 2008, in the parallel district court proceeding in the Delaware 
District  Court  proceeding  against  Samsung  that  is  currently  stayed,  InterDigital  and  Samsung 
advised the Delaware District Court of the Samsung Term Sheet.

On  January  14,  2009,  InterDigital  and  Samsung  entered  into  the  2009  Samsung  PLA,  which 
superseded the terms of the Samsung Term Sheet. Under the terms of the 2009 Samsung PLA, 
Samsung  has  agreed  to  pay  InterDigital  $400.0  million  in  four  equal  installments  over  an 
18-month  period  to  resolve  their  outstanding  disputes,  including  the  USITC Action  against 
Samsung  and  the  related  Delaware  District  Court  proceeding.  Under  the  terms  of  the  2009 
Samsung  PLA,  InterDigital  has  agreed  to  grant  Samsung  a  royalty-bearing  license  covering 
Samsung’s sale of 3G products (including products built under both the WCDMA and cdma2000 
standards  and  certain  of  their  related  extensions)  through  2012,  and  a  license  covering 
Samsung’s sale of 2G single-mode TDMA-based products that will become paid-up in 2010.

On  January  30,  2009,  Samsung  made  its  first  required  payment  under  the  2009  Samsung  
PLA,  and  on  February  3,  2009  the  parties  jointly  moved  to  terminate  the  Samsung  USITC 
Action.  On  February  6,  2009,  the Administrative  Law  Judge  terminated  the  USITC Action.  On 
February  3,  2009,  the  court  in  the  related  Delaware  District  Court  proceeding  dismissed  that 
action following a joint stipulation of dismissal filed by the parties on February 2, 2009.

Samsung Delaware Proceeding

In  March  2007,  Samsung Telecommunications America  LLP  and  Samsung  Electronics  Co.,  Ltd. 
(collectively “Samsung”) filed an action against InterDigital Communications Corporation (now 
IDC), ITC and another affiliate, Tantivy Communications, Inc. (collectively “InterDigital”), in the 
Delaware  District  Court  (the “Samsung  Delaware  Proceeding”),  alleging  that  InterDigital  had 

86       I N T E R D I G I TA L  2 0 0 8   A R

refused to comply with its alleged contractual obligations to be prepared to license our patents 
on fair, reasonable, and non-discriminatory (“FRAND”) terms and that InterDigital had allegedly 
engaged  in  unfair  business  practices.  By  their  original  Complaint  in  the  action,  Samsung 
sought damages and declaratory relief, including declarations that: (i) InterDigital’s patents and 
patent applications allegedly promoted to standards bodies are unenforceable, (ii) the Samsung 
entities  have  a  right  to  practice  InterDigital’s  intellectual  property  as  a  result  of  an  alleged 
license from QUALCOMM Incorporated, (iii) nine specified InterDigital patents are invalid and/
or not infringed by the Samsung entities, and (iv) InterDigital must offer the Samsung entities a 
license  on  FRAND  terms.  In  September  2007,  Samsung  filed  a  First Amended  Complaint  that 
omitted  the  previously  asserted  claims  for  declaratory  judgment  regarding  the  nine  specified 
InterDigital patents. In November 2007, InterDigital filed its Answer to the Amended Complaint, 
disputing  Samsung’s  allegations  and  asserting  counterclaims  of  infringement  as  to  two 
InterDigital patents.

As  discussed  above,  in  November  2008,  InterDigital  and  Samsung  entered  into  the  Samsung 
Term Sheet resolving their disputes. Pursuant to the Samsung Term Sheet, in December 2008, 
Samsung  and  InterDigital  filed  a  joint  stipulation  to  stay  the  Samsung  Delaware  Proceeding 
until  February  9,  2009,  which  was  granted.  On  January  14,  2009,  InterDigital  and  Samsung 
entered into the 2009 Samsung PLA, superseding the Samsung Term Sheet and providing for, 
among other things, the dismissal of the Samsung Delaware Proceeding.

On  January  30,  2009,  Samsung  made  its  first  required  payment  under  the  2009  Samsung  
PLA. Thereafter,  on  February  2,  2009,  the  parties  jointly  moved  to  dismiss  this  matter.  On 
February 3, 2009, the court in the Samsung Delaware Proceeding dismissed that action.

Samsung 2nd Arbitration and Related Enforcement Action

Since  February  2002,  InterDigital  and  Samsung  Electronics  Co.,  Ltd.  (“Samsung”)  have  been 
engaged  in  a  series  of  disputes  concerning  the  royalties  owed  by  Samsung  for  sales  of  2G 
products  under  the  parties’  1996  patent  license  agreement.  In  November  2003,  Samsung 
initiated  an  arbitration  proceeding  with  InterDigital  (the “Samsung  2nd Arbitration”)  in  the 
International  Chamber  of  Commerce  concerning  the  royalties  owed  by  Samsung  on  sales  of 
2G  products  during  the  2002  to  2006  timeframe.  In  August  2006,  the  arbitral  tribunal 
(“Tribunal”) in the Samsung 2nd Arbitration issued a final award (“Award”), ordering Samsung 
to  pay  InterDigital  approximately  $134.0  million  in  past  royalties,  plus  interest,  on  Samsung’s 
sale  of  single  mode  2G  GSM/TDMA  and  2.5G  GSM/GPRS/EDGE  terminal  units  for  the  period 
from  2002  through  2005. The Tribunal  also  established  the  royalty  rates  to  be  applied  to 
Samsung’s sales of covered 2G products in 2006.

In  September  2006,  InterDigital  filed  an  action  seeking  to  enforce  the  arbitral  Award  in  
the  U.S.  District  Court  for  the  Southern  District  of  New York  (“Enforcement  Action”).  On  
December 10, 2007, the court in the Enforcement Action confirmed the Award in its entirety and 
directed  that  Samsung  pay  InterDigital  the  amount  of  the Award,  plus  interest,  for  a  total 
judgment  of  approximately  $150.3  million.  On  December  18,  2007,  Samsung  filed  an  appeal 
with  the  United  States  Court  of Appeals  for  the  Second  Circuit,  and  posted  an  appeal  bond 
with  the  district  court  in  the  amount  of  approximately  $166.7  million.  By  posting  the  appeal 
bond, Samsung stayed execution of the Order of Judgment pending the appeal. Oral argument 
in the appeal was scheduled for December 17, 2008.

As  discussed  above,  in  November  2008,  InterDigital  and  Samsung  entered  into  the  Samsung 
Term  Sheet,  settling  their  2G  and  3G  disputes.  Pursuant  to  the  Samsung Term  Sheet,  in 
December  2008,  Samsung  and  InterDigital  filed  a  joint  request  to  stay  the  appeal  in  the 
Enforcement Action.  On  January  14,  2009,  InterDigital  and  Samsung  entered  into  the  2009 
Samsung  PLA,  which  superseded  the  Samsung Term  Sheet  and  provided  for,  among  other 
things,  the  dismissal  of  the  2G  disputes,  including  the  appeal  of  the  Enforcement Action.  On 

I N T E R D I G I TA L  2 0 0 8   A R   87

January 30, 2009, Samsung made its first required payment under the 2009 Samsung PLA. On 
February  3,  2009,  the  parties  jointly  moved  to  dismiss  the  appeal  of  the  Enforcement Action, 
and  to  release  the  appeal  bond  posted  by  Samsung.  On  February  5,  2009,  the  Second  Circuit 
granted the parties’ dismissal request.

Samsung 3rd Arbitration

In  October  2006,  Samsung  Electronics  Co.,  Ltd.  (“Samsung”)  filed  a  Request  for Arbitration 
(“Samsung 3rd Arbitration”) with the International Chamber of Commerce against InterDigital 
relating to the royalties Samsung owed for the period 2002 through 2006, which had been the 
subject  of  the  Samsung  2nd Arbitration.  In  the  Samsung  3rd Arbitration,  Samsung  sought  to 
have a new arbitration panel determine new royalty rates for Samsung’s 2G/2.5G GSM/GPRS/
EDGE  product  sales  based  on  the  April  2006  Arbitration  Settlement  Agreement  between 
InterDigital  and  Nokia  (“Nokia  Settlement”).  Samsung  purported  to  have  elected  the  Nokia 
Settlement under the most favored licensee (“MFL”) clause in the 1996 Samsung PLA. Samsung 
contended that it had the right to have a new rate, based on the Nokia Settlement, applied to 
its  sales  in  the  period  from  January  1,  2002  through  December  31,  2006  in  lieu  of  the  royalty 
rates that had been determined by the Tribunal in the Samsung 2nd Arbitration for that period. 
InterDigital  denied  that  Samsung  was  entitled  to  receive  any  new  royalty  rate  adjustment 
based  on  the  Nokia  Settlement,  and  counterclaimed,  seeking  an  Award  of  the  royalties 
Samsung  owes  for  its  2G/2.5G  sales  in  2006  at  the  royalty  rate  specified  in  the August  2006 
Award in the Samsung 2nd Arbitration.

In  February  2008,  the  arbitral  tribunal  heard  oral  argument  on  the  issue  of  whether  Samsung 
was  entitled  to  elect  the  Nokia  Settlement.  In  July  2008,  the  arbitral  tribunal  in  the  Samsung 
3rd  Arbitration  issued  a  Partial  Final  Award,  finding  that  Samsung  was  not  entitled  to  an 
adjustment of its royalty obligations based on the Nokia Settlement.

As  discussed  above  with  respect  to  the  USITC Action,  in  November  2008,  InterDigital  and 
Samsung entered into the Samsung Term Sheet settling their 2G and 3G disputes. Pursuant to 
the Samsung Term Sheet, in December 2008, Samsung and InterDigital filed a joint request to 
stay the Samsung 3rd Arbitration. On January 14, 2009, InterDigital and Samsung entered into 
the 2009 Samsung PLA, which superseded the Samsung Term Sheet and provided for, among 
other  things,  the  dismissal  of  the  2G  disputes,  including  the  Samsung  3rd Arbitration.  On 
January 30, 2009, Samsung made its first required payment under the 2009 Samsung PLA, and 
on  February  2,  2009,  the  parties  jointly  moved  to  dismiss  the  Samsung  3rd Arbitration.  On 
February 19, 2009, the arbitral tribunal in the Samsung 3rd Arbitration issued an Agreed Order 
dismissing the arbitration.

Nokia Litigation

Nokia USITC Proceeding and Related Delaware District Court and Southern District of New 
York Proceedings

In August 2007, InterDigital filed a USITC Complaint against Nokia Corporation and Nokia, Inc. 
(collectively, “Nokia”)  alleging  that  Nokia  engaged  in  an  unfair  trade  practice  by  selling  for 
importation  into  the  United  States,  importing  into  the  United  States,  and  selling  after 
importation  into  the  United  States,  certain  3G  mobile  handsets  and  components  that  infringe 
two of InterDigital’s patents. In November and December 2007, a third patent and fourth patent, 
respectively,  were  added  to  our  Complaint  against  Nokia. The  Complaint  seeks  an  exclusion 
order barring from entry into the United States infringing 3G mobile handsets and components 
that are imported by or on behalf of Nokia. Our Complaint also seeks a cease-and-desist order 
to  bar  further  sales  of  infringing  Nokia  products  that  have  already  been  imported  into  the 
United States.

88       I N T E R D I G I TA L  2 0 0 8   A R

In addition, on the same date as our filing of the USITC action referenced above, we also filed 
a  Complaint  in  the  Delaware  District  Court  alleging  that  Nokia’s  3G  mobile  handsets  and 
components  infringe  the  same  two  InterDigital  patents  identified  in  the  original  USITC 
Complaint. This  Delaware  action  was  stayed  on  January  10,  2008,  pursuant  to  the  mandatory, 
statutory  stay  of  parallel  district  court  proceedings  at  the  request  of  a  respondent  in  a  USITC 
investigation. Thus, this Delaware action is stayed until the USITC’s determination in this matter 
becomes final. The Delaware District Court permitted InterDigital to add to the stayed Delaware 
action the third and fourth patents InterDigital asserted against Nokia in the USITC action.

Nokia, joined by Samsung, moved to consolidate the Samsung and Nokia USITC proceedings. 
On October 24, 2007, the Honorable Paul J. Luckern, the Administrative Law Judge overseeing 
the  two  USITC  proceedings  against  Samsung  and  Nokia,  respectively,  issued  an  Order  to 
consolidate  the  two  pending  investigations.  Pursuant  to  the  Order,  the  schedules  for  both 
investigations were revised to consolidate proceedings and set a unified evidentiary hearing on 
April 21-28, 2008, the filing of a single initial determination by Judge Luckern by July 11, 2008, 
and a target date for the consolidated investigations of November 12, 2008, by which date the 
USITC would issue its final determination (the “Target Date”).

On  December  4,  2007,  Nokia  moved  for  an  order  terminating  or,  alternatively,  staying  the 
USITC investigation as to Nokia, on the ground that Nokia and InterDigital must first arbitrate a 
dispute as to whether Nokia is licensed under the patents asserted by InterDigital against Nokia 
in the USITC investigation. On January 8, 2008, Judge Luckern issued an order denying Nokia’s 
motion and holding that Nokia has waived its arbitration defense by instituting and participating 
in the investigation and other legal proceedings. On February 13, 2008, Nokia filed an action in 
the  U.S.  District  Court  for  the  Southern  District  of  New York,  seeking  to  preliminarily  enjoin 
InterDigital  from  proceeding  with  the  USITC  investigation  with  respect  to  Nokia,  in  spite  of 
Judge  Luckern’s  ruling  denying  Nokia’s  motion  to  terminate  the  USITC  investigation.  Nokia 
raised  in  this  preliminary  injunction  action  the  same  arguments  it  raised  in  its  motion  to 
terminate  the  USITC  investigation,  namely  that  InterDigital  allegedly  must  first  arbitrate  its 
alleged license dispute with Nokia and that Nokia has not waived arbitration of this defense. In 
the  Southern  District Action,  Nokia  also  sought  to  compel  InterDigital  to  arbitrate  its  alleged 
license  dispute  with  Nokia  and,  in  the  alternative,  seeks  a  determination  by  the  District  Court 
that  Nokia  is  licensed  under  the  patents  asserted  by  InterDigital  against  Nokia  in  the  USITC 
investigation.  On  March  7,  2008,  InterDigital  filed  a  motion  to  dismiss  Nokia’s  claim  in  the 
alternative that Nokia is licensed under the patents asserted by InterDigital against Nokia in the 
USITC investigation. The District Court has not acted on InterDigital’s motion to dismiss.

On  February  8,  2008,  Nokia  filed  a  motion  for  summary  determination  in  the  USITC  that 
InterDigital cannot show that a domestic industry exists in the United States as required to obtain 
relief.  Samsung  joined  this  motion.  InterDigital  opposed  this  motion.  On  February  14,  2008, 
InterDigital  filed  a  motion  for  summary  determination  that  InterDigital  satisfies  the  domestic 
industry requirement based on its licensing activities. On February 26, 2008, InterDigital filed a 
motion  for  summary  determination  that  it  has  separately  satisfied  the  so-called “economic 
prong”  for  establishing  that  a  domestic  industry  exists  based  on  InterDigital’s  chipset  product 
that practices the asserted patents. Samsung and Nokia opposed these motions. On March 17, 
2008,  Samsung  and  Nokia  filed  a  motion  to  strike  any  evidence  concerning  InterDigital’s 
product and to preclude InterDigital from introducing any such evidence in relation to domestic 
industry at the evidentiary hearing. On March 26, 2008, the Administrative Law Judge granted 
InterDigital’s  motion  for  summary  determination  that  it  has  satisfied  the  so-called “economic 
prong”  for  establishing  that  a  domestic  industry  exists  based  on  InterDigital’s  chipset  product 
that  practices  the  asserted  patents  and  denied  Samsung’s  motion  to  strike  and  preclude 
introduction of evidence concerning InterDigital’s domestic industry product.

I N T E R D I G I TA L  2 0 0 8   A R   89

On February 27, 2008, Nokia filed a motion to extend the Target Date in the USITC proceeding. 
Samsung  joined  Nokia’s  motion.  InterDigital  opposed  this  motion.  On  March  11,  2008,  the 
Administrative Law Judge denied Nokia’s motion to extend the Target Date.

On  March  17,  2008,  Nokia  and  Samsung  jointly  moved  for  summary  determination  that  U.S. 
Patent  No.  6,693,579,  which  was  asserted  against  both  Samsung  and  Nokia,  is  invalid,  and 
Samsung moved for summary determination on its defense of equitable estoppel. InterDigital 
opposed  these  motions.  On  April  14,  2008,  the  Administrative  Law  Judge  denied  Nokia’s  
and  Samsung’s  joint  motion  for  summary  determination  that  the  ‘579  patent  is  invalid  
and  also  denied  Samsung’s  motion  for  summary  determination  of  Samsung’s  defense  of  
equitable estoppel.

On March 20, 2008, the U.S. District Court for the Southern District of New York, ruling from the 
bench, decided that Nokia is likely to prevail on the issue of whether Nokia’s alleged entitlement 
to a license is arbitrable. The Court did not consider or rule on whether Nokia is entitled to such 
a  license. As  a  result,  the  Court  ordered  InterDigital  to  participate  in  arbitration  of  the  license 
issue. The  Court  also  entered  a  preliminary  injunction  requiring  InterDigital  to  cease 
participation  in  the  USITC  proceeding  by April  11,  2008,  but  only  with  respect  to  Nokia. The 
Court further ordered Nokia to post a $500,000 bond by March 28, 2008. InterDigital promptly 
filed  a  request  for  a  stay  of  the  preliminary  injunction  and  for  an  expedited  appeal  with  the 
U.S. Court of Appeals for the Federal Circuit, which transferred the appeal to the U.S. Court of 
Appeals  for  the  Second  Circuit. The  preliminary  injunction  became  effective  on April  11,  2008, 
and,  in  accordance  with  the  Court’s  order,  InterDigital  filed  a  motion  with  the Administrative 
Law  Judge  to  stay  the  USITC  proceeding  against  Nokia  pending  InterDigital’s  appeal  of  the 
District  Court’s  decision  or,  if  that  appeal  is  unsuccessful,  pending  the  Nokia TDD Arbitration 
(described  below).  On April  14,  2008,  the Administrative  Law  Judge  ordered  that  the  date  for 
the  commencement  of  the  evidentiary  hearing,  originally  scheduled  for April  21,  2008,  be 
suspended  until  further  notice  from  the Administrative  Law  Judge. The Administrative  Law 
Judge  did  not  at  that  point  change  the  scheduled  date  of  July  11,  2008  for  his  initial 
determination  in  the  investigation  or  the  scheduled Target  Date  of  November  12,  2008  for  a 
decision by the USITC. InterDigital’s motion for a stay of the preliminary injunction and for an 
expedited appeal was considered by a panel of the Second Circuit on April 15, 2008. On April 
16, 2008, the Second Circuit denied the motion for stay but set an expedited briefing schedule 
for  resolving  InterDigital’s  appeal  on  the  merits  of  whether  the  District  Court’s  order  granting 
the preliminary injunction should be reversed.

On April  17,  2008,  InterDigital  filed  a  motion  with  the  USITC  to  separate  the  consolidated 
investigations  against  Nokia  and  Samsung  in  order  for  the  investigation  to  continue  against 
Samsung  pending  the  expedited  appeal  or,  if  the  appeal  is  unsuccessful,  pending  the  Nokia 
TDD Arbitration.  Samsung  and  Nokia  opposed  InterDigital’s  motion.  On  May  16,  2008,  the 
Administrative  Law  Judge  deconsolidated  the  investigations  against  Samsung  and  Nokia  and 
set an evidentiary hearing date in the investigation against Samsung (337-TA-601) to begin on 
July 8, 2008.

On May 20, 2008, the Administrative Law Judge denied without prejudice all pending motions 
in the consolidated investigation (337-TA-613). On May 22, 2008, the Administrative Law Judge 
reset the Target Date for the USITC’s Final Determination in the Samsung investigation (337-TA-
601) to March 25, 2009, requiring a final Initial Determination by the Administrative Law Judge 
to be entered no later than November 25, 2008.

On  June  17,  2008,  a  panel  of  the  U.S.  Court  of  Appeals  for  the  Second  Circuit  heard  oral 
argument  on  InterDigital’s  appeal  from  the  Order  of  the  U.S.  District  Court  for  the  Southern 
District  of  New York  preliminarily  enjoining  InterDigital  from  proceeding  against  Nokia  in  the 
consolidated  investigation.  On  July  31,  2008,  the  Second  Circuit  reversed  the  preliminary 

90       I N T E R D I G I TA L  2 0 0 8   A R

injunction, finding that Nokia’s litigation conduct resulted in a waiver of any right to arbitrate its 
license  dispute.  InterDigital  promptly  notified  the  Administrative  Law  Judge  in  the  Nokia 
investigation  (337-TA-613)  of  the  Second  Circuit’s  decision.  On August  14,  2008,  Nokia  filed  a 
petition  for  rehearing  and  petition  for  rehearing  en  banc  of  the  Second  Circuit’s  decision,  and 
on  September  15,  2008,  the  Second  Circuit  denied  Nokia’s  petitions. The  mandate  from  the 
Second  Circuit  issued  to  the  Southern  District  of  New York  on  September  22,  2008. 
Notwithstanding the Second Circuit’s decision, on October 17, 2008 Nokia filed a request for a 
status conference with the District Court to establish a procedural schedule for Nokia to pursue 
a  permanent  injunction  requiring  InterDigital  to  arbitrate  Nokia’s  alleged  license  defense,  and 
arguing  that  the  Second  Circuit’s  decision  was  rendered  in  the  context  of  a  preliminary 
injunction and does not bar such an action. On October 23, 2008, InterDigital filed a response 
with  the  District  Court  asserting  that  the  Second  Circuit’s  waiver  finding  is  dispositive  of  any 
claim  for  arbitration  of  Nokia’s  alleged  license  defense  and  requesting  the  District  Court  to 
address InterDigital’s entitlement to recover against the $500,000 bond posted by Nokia as well 
as InterDigital’s pending motion to dismiss Nokia’s claim in the alternative for a determination 
by  the  District  Court  that  Nokia  is  licensed  under  the  patents  asserted  by  InterDigital  against 
Nokia  in  the  USITC  investigation.  On  October  30,  2008,  Nokia  filed  a  reply  with  the  District 
Court. The District Court has not yet acted on the parties’ filings.

On  September  24,  2008,  InterDigital  filed  a  motion  to  lift  the  stay  of  the  Nokia  investigation 
(337-TA-613) based on the issuance of the Second Circuit’s mandate reversing the preliminary 
injunction  granted  to  Nokia. The Administrative  Law  Judge  granted  InterDigital’s  motion  on 
September  25,  2008  and  lifted  the  stay.  On  October  7,  2008,  the Administrative  Law  Judge 
issued an Order in the Nokia investigation setting the evidentiary hearing for May 26-29, 2009. 
On  October  10,  2008,  the Administrative  Law  Judge  issued  an  Order  resetting  the Target  Date 
for  the  USITC’s  Final  Determination  in  the  Nokia  investigation  to  December  14,  2009,  and 
requiring  a  final  Initial  Determination  by  the Administrative  Law  Judge  to  be  entered  no  later 
than August 14, 2009.

On  January  21,  2009,  Nokia  filed  a  motion  to  schedule  a  claim  construction  hearing  in  early 
February  2009,  and  on  January  29,  2009,  InterDigital  filed  an  opposition  to  the  motion  for  a 
claim construction hearing. On February 9, 2009, the Administrative Law Judge denied Nokia’s 
motion for a claim construction hearing.

On  February  13,  2009,  InterDigital  filed  a  renewed  motion  for  summary  determination  that 
InterDigital  has  satisfied  the  domestic  industry  requirement  based  on  its  licensing  activities, 
and on February 27, 2009, Nokia filed an opposition to the motion. The parties await a ruling on 
this summary determination motion by the Administrative Law Judge.

The  evidentiary  hearing  for  the  Nokia  investigation  (337-TA-613)  remains  scheduled  for  
May 26-29, 2009.

Nokia TDD Arbitration

On  April  1,  2008,  Nokia  Corporation  filed  a  Request  for  Arbitration  with  the  International 
Chamber of Commerce against InterDigital, Inc., IDC and ITC, seeking a declaration that Nokia 
is licensed under the patents asserted by InterDigital against Nokia in the USITC investigation 
pursuant to the parties’ TDD Development Agreement. InterDigital believes that Nokia’s request 
for declaratory relief in the TDD Arbitration is meritless.

On  May  9,  2008,  InterDigital  filed  an Answer  to  Nokia’s  Request  for Arbitration,  requesting, 
inter alia : (i) that the arbitration be dismissed because the dispute is not arbitrable and, even if 
arbitrable,  Nokia  waived  its  right  to  arbitration;  and,  in  the  alternative,  (ii)  a  declaration  that 
Nokia is not licensed to the patents at issue in the USITC investigation pursuant to the parties’ 
TDD Development Agreement.

I N T E R D I G I TA L  2 0 0 8   A R   91

On July 17, 2008, the arbitral tribunal was constituted.

On July 31, 2008, as discussed above, the United States Court of Appeals for the Second Circuit 
reversed the district court’s grant of an order requiring InterDigital to submit the TDD issue to 
arbitration, finding that Nokia waived any right to arbitrate the issue. InterDigital believes that 
Nokia  should  not  be  permitted  to  continue  to  pursue  this  arbitration  in  light  of  the  Second 
Circuit’s  finding  of  waiver  and  has  requested  that  the  arbitration  be  dismissed.  Nokia  has 
asserted  that  the  Second  Circuit’s  decision  is  not  a  final  decision  on  the  issue  of  waiver,  and 
that  Nokia  may  submit  the  waiver  issue  to  the  arbitral  tribunal  or,  as  indicated  above,  to  the 
District Court on remand. On October 27, 2008, the arbitral tribunal notified the parties that the 
drafting of the Terms of Reference for the arbitration is postponed until such time as the status 
conference  before  Judge  Batts  in  the  U.S.  District  Court  for  the  Southern  District  of  New York 
has been held (see “Nokia USITC Proceeding and Related Delaware District Court and Southern 
District of New York Proceedings” above).

Nokia Delaware Proceeding

In  January  2005,  Nokia  filed  a  Complaint  in  the  United  States  District  Court  for  the  District  of 
Delaware  (“Delaware  District  Court”)  against  InterDigital  Communications  Corporation  (now 
IDC) and ITC (for purposes of the Nokia Delaware Proceeding described herein, IDC and ITC are 
collectively  referred  to  as “InterDigital,” “we,”  or “our”),  alleging  that  we  have  used  false  or 
misleading  descriptions  or  representations  regarding  our  patents’  scope,  validity,  and 
applicability  to  products  built  to  comply  with  3G  wireless  phone  Standards  (“Nokia  Delaware 
Proceeding”). We subsequently filed counterclaims based on Nokia’s licensing activities as well 
as Nokia’s false or misleading descriptions or representations regarding Nokia’s 3G patents and 
Nokia’s undisclosed funding and direction of an allegedly independent study of the essentiality 
of 3G patents.

On  December  10,  2007,  pursuant  to  a  joint  request  by  the  parties,  the  Delaware  District  Court 
entered an Order staying the proceedings pending the full and final resolution of the Company’s 
USITC investigation against Nokia and Samsung. Specifically, the full and final resolution of the 
USITC investigation includes any initial or final determinations of the Administrative Law Judge 
overseeing the proceeding, the USITC, and any appeals therefrom. Pursuant to the Order, the 
parties  and  their  affiliates  are  generally  prohibited  from  initiating  against  the  other  parties,  in 
any  forum,  any  claims  or  counterclaims  that  are  the  same  as  the  claims  and  counterclaims 
pending  in  the  Nokia  Delaware  Proceeding,  and  should  any  of  the  same  or  similar  claims  or 
counterclaims be initiated by a party, the other parties may seek dissolution of the stay.

Except for the Nokia Delaware Proceeding and the Nokia Arbitration Concerning Presentations 
(described  below),  the  Order  does  not  affect  any  of  the  other  legal  proceedings  between  the 
parties,  including  the  USITC  investigation  involving  InterDigital  and  Nokia,  or  the  parallel 
Delaware District Court proceeding also brought by InterDigital against Nokia.

Nokia Arbitration Concerning Presentations

In November 2006, InterDigital Communications Corporation (now IDC) and ITC filed a Request 
for Arbitration with the International Chamber of Commerce against Nokia (“Nokia Arbitration 
Concerning Presentations”), claiming that certain presentations Nokia has attempted to use in 
support  of  its  claims  in  the  Nokia  Delaware  Proceeding  are  confidential  and,  as  a  result,  may 
not be used in the Nokia Delaware Proceeding pursuant to the parties’ agreement.

92       I N T E R D I G I TA L  2 0 0 8   A R

The  December  10,  2007  Order  entered  by  the  Delaware  District  Court  to  stay  the  Nokia 
Delaware  Proceeding  (described  above)  also  stayed  the  Nokia  Arbitration  Concerning 
Presentations pending the full and final resolution of the USITC investigation against Nokia as 
described above.

Nokia UKII and UKIII Actions

On  March  14,  2008,  Nokia  applied  to  the  English  High  Court  of  Justice,  Chancery  Division, 
Patents  Court  (“English  High  Court”)  to  stay  the  action  initiated  by  ITC  in  December  2006 
(“UKIII”) with respect to six Nokia patents that are subject to opposition proceedings brought 
by a third party before the European Patent Office. ITC opposed Nokia’s application for a stay. 
On April 8, 2008, the Court denied Nokia’s application for a stay.

During  the  proceedings  in  the  action  before  the  English  High  Court  initiated  by  Nokia  in  July 
2005  (“UKII”),  Nokia  made  statements  to  the  Court  that  it  was  not  licensed  under  any 
InterDigital patents. After judgment, Nokia claimed to be licensed to an undetermined number 
of InterDigital patents. On April 3, 2008, InterDigital applied to re-open the English High Court’s 
judgment  on  the  issue  of  discretion,  and  the  hearing  of  this  application  was  scheduled  for 
September 15, 2008.

In  the  UKIII  action,  the  Court  had  scheduled  a  preliminary  hearing  for  June  30,  2008  with 
respect  to  whether  the  Judge  should  exercise  his  discretion  to  issue  the  declaration  being 
sought by ITC. Trial in the UKIII action was scheduled to begin in the fourth quarter of 2008.

The UKII and UKIII actions, relating to the essentiality of both ITC and Nokia patents registered 
in  the  United  Kingdom,  were  brought  to  an  end  on  July  2,  2008,  pursuant  to  a  confidential 
agreement between the parties. The UKIII preliminary hearing scheduled for June 30, 2008 did 
not commence before the action was ended.

During  first  half  2008,  we  reduced  our  accrual  for  the  potential  reimbursement  of  Nokia’s 
attorney’s  fees  associated  with  the  UKII  action  from  $7.8  million,  which  was  accrued  in  2007,  
to  $6.6  million. As  a  result  of  the  resolutions  of  the  UKII  and  UKIII  actions,  we  recognized  a  
$2.6 million one-time reduction to expenses in third quarter 2008.

Other

We  have  filed  patent  applications  in  the  United  States  and  in  numerous  foreign  countries.  In 
the ordinary course of business, we currently are, and expect from time-to-time to be, subject 
to  challenges  with  respect  to  the  validity  of  our  patents  and  with  respect  to  our  patent 
applications. We intend to continue to vigorously defend the validity of our patents and defend 
against any such challenges. However, if certain key patents are revoked or patent applications 
are denied, our patent licensing opportunities could be materially and adversely affected.

We  and  our  licensees,  in  the  normal  course  of  business,  may  have  disagreements  as  to  the 
rights  and  obligations  of  the  parties  under  the  applicable  patent  license  agreement.  For 
example, we could have a disagreement with a licensee as to the amount of reported sales of 
covered  products  and  royalties  owed.  Our  patent  license  agreements  typically  provide  for 
arbitration  as  the  mechanism  for  resolving  disputes. Arbitration  proceedings  can  be  resolved 
through  an  award  rendered  by  an  arbitration  panel  or  through  private  settlement  between  
the parties.

In  addition  to  disputes  associated  with  enforcement  and  licensing  activities  regarding  our 
intellectual property, including the litigation and other proceedings described above, we are a 
party to other disputes and legal actions not related to our intellectual property, but also arising 
in the ordinary course of our business, including claims by us for insurance coverage involving 

I N T E R D I G I TA L  2 0 0 8   A R   93

the Nokia Delaware Proceeding. Based upon information presently available to us, we believe 
that  the  ultimate  outcome  of  these  other  disputes  and  legal  actions  will  not  have  a  material 
adverse affect on us.

Among the types of legal proceedings we encounter in the normal course of business, we are 
engaged in the following action:

Federal

In May 2007, the Arbitrator in the arbitration proceeding between InterDigital Communications 
Corporation  (now  IDC)  and  ITC  (collectively,  for  purposes  of  the  Federal  arbitration  described 
herein, “InterDigital,” “we,” or “our”) and Federal Insurance Company (“Federal”), and relating 
to a Litigation Expense and Reimbursement Agreement signed in February 2000 by the parties 
(“Reimbursement Agreement”), refused to award the full amount of Federal’s claim, which was 
in  excess  of  $33.0  million. The  Arbitrator  did  award  Federal  approximately  $13.0  million, 
pursuant  to  a  formula  set  forth  in  the  Reimbursement  Agreement,  for  reimbursement  of 
attorney’s  fees  and  expenses  previously  paid  to  or  on  behalf  of  InterDigital  by  Federal,  plus 
approximately  $2.0  million  in  interest. As  additional  reimbursement  of  attorney’s  fees  and 
expenses,  the Arbitrator  awarded  $5.0  million,  without  interest,  as  Federal’s  share  under  the 
Reimbursement Agreement  of “additional  value”  of  the  2003  settlement  between  InterDigital 
and  Ericsson  Inc.  Further,  the Arbitrator  ruled  that  InterDigital  must  pay  Federal  10%  of  any 
additional payments InterDigital may receive as a result of an audit of Sony Ericsson’s sales. In 
June 2007, we notified Federal that we had received $2.0 million from Sony Ericsson to resolve 
Sony  Ericsson’s  payment  obligations  following  an  audit. The  approximately  $13.0  million 
portion  of  the Award  represents  a  percentage  of  the  amounts  InterDigital  has  received  since 
March 2003 from Telefonaktiebolaget LM Ericsson and Ericsson Inc. and Sony Ericsson Mobile 
Communications AB under their respective patent license agreements.

In  June  2007,  Federal  moved  to  confirm  the Award  in  the  United  States  District  Court  for  the 
Eastern District of Pennsylvania. Also in June 2007, we filed an opposition to Federal’s motion 
to confirm the arbitration Award and a cross motion to vacate a portion of the Award, totaling 
approximately  $14.5  million,  on  the  ground  that  the Arbitrator  exceeded  the  scope  of  her 
authority. We also moved the Court to stay confirmation of the Award pending adjudication of 
our  recoupment  defense  whereby  we  are  seeking  to  recoup  the  full  amount  of  the Award 
based  on  Federal’s  bad  faith  breach  of  its  contractual  and  fiduciary  duties  to  us.  In  July  2007, 
the  Court  heard  oral  arguments  on  Federal’s  motion  to  confirm  the Award,  our  opposition 
thereto,  and  our  cross  motion  to  vacate  the  Award  and  to  stay  confirmation  pending 
adjudication  of  our  recoupment  defense.  On  March  24,  2008,  the  Court:  (i)  granted  Federal’s 
motion  to  confirm  the  arbitration  award;  and  (ii)  denied  InterDigital’s  motion  to  stay 
confirmation  of  the  arbitration  award  pending  adjudication  of  InterDigital’s  claim  
for  recoupment  based  on  Federal’s  bad  faith  breach  of  its  duties  as  InterDigital’s  insurer.  On 
April 1, 2008, InterDigital filed a notice of appeal to the United States Court of Appeals for the 
Third  Circuit.  In  order  to  stay  execution  on  Federal’s  judgment  pending  appeal,  InterDigital 
deposited  $23.0  million  with  the  Clerk  of  the  Court,  an  amount  sufficient  to  secure  Federal’s 
judgment  and  anticipated  interest  until  decision  by  the  Court  of Appeals.  On April  10,  2008,  
the  Court  extended  Federal’s  deadline  for  seeking  costs  and  fees  until  after  conclusion  of  
the appeal.

On May 6, 2008, the Court of Appeals assigned the matter for mediation in the Court of Appeals 
mediation  program. The  mediation  program  concluded  without  any  settlement.  Consequently, 
InterDigital and Federal have commenced briefing the appeal.

94       I N T E R D I G I TA L  2 0 0 8   A R

On  July  7,  2008,  the  Company  filed  its  opening  brief,  seeking  reversal  of  the  District  Court’s 
refusal to hear InterDigital’s recoupment claim and remand to the District Court for adjudication 
of  such  claim  as  a  set-off  to  Federal’s  arbitration  award.  Federal’s  brief  was  filed  on August  6, 
2008. The Company’s reply brief was filed on August 20, 2008. The appeal was submitted to the 
Court of Appeals on January 8, 2009. On January 29, 2009, the Court of Appeals affirmed the 
District  Court’s  March  24,  2008  Order.  On  February  23,  2009,  Federal  moved  to  lift  the  stay  of 
enforcement of Federal’s judgment.

At  the  time  of  judgment  in  second  quarter  2007,  we  recorded  an  expense  of  approximately 
$16.6  million,  which  represents  the  total  amount  of  the Award  through  second  quarter  2007, 
less  the  amount  of  a  previously  accrued  liability  of  $3.4  million. We  have  also  accrued  post 
judgment  net  interest  expense  of  $1.6  million  ($0.9  million  during  2008)  and  reported  such 
interest  expense  within  the “Interest  and  other  income,  net”  line  item  in  our  Consolidated 
Statements of Income.

9.  InsURance  ReIMbUR seMe nTs

During 2008 and 2007, we received payments from insurance providers of $7.2 million and $1.7 
million, respectively, to reimburse us for portions of our defense costs in certain litigation with 
Nokia. These  amounts  reduced  our  patent  administration  and  licensing  expenses  in  2008  and 
2007. We did not receive any such reimbursements during 2006.

10.  Re la TeD  P aRTY TRansacTIons

One of our outside directors is Chairman of the Advisory Board to a firm that provides us with 
consulting  services. We  paid  less  than  $0.1  million  to  this  firm  for  their  services  in  2008,  $0.3 
million  in  2007  and  we  paid  them  less  than  $0.1  million  in  2006.  Our  board  member  did  not 
receive any direct compensation or commissions related to these engagements.

Common Stock Compensation Plans

We  have  stock-based  compensation  plans  under  which,  depending  on  the  plan,  directors, 
employees,  consultants  and  advisors  can  receive  share-based  awards  such  as,  stock  options, 
stock  appreciation  rights,  restricted  stock  awards  and  other  stock  unit  awards. We  issue  the 
share-based awards authorized under these plans through a variety of compensation programs.

Common Stock Option Plans

We  have  granted  options  under  two  incentive  stock  option  plans,  three  non-qualified  stock 
option plans and two plans which provide for grants of both incentive and non-qualified stock 
options (Pre-existing Plans) to non-employee directors, officers and employees of the Company 
and  other  specified  groups,  depending  on  the  plan.  No  further  grants  are  allowed  under  the 
Pre-existing  Plans.  In  2000,  our  shareholders  approved  the  2000  Stock Award  and  Incentive 
Plan (2000 Plan) that allows for the granting of incentive and non-qualified options, as well as 
other securities. The 2000 Plan authorizes the offer and sale of up to approximately 6.9 million 
shares of common stock. The Board of Directors or the Compensation Committee of the Board 
determines the number of options to be granted. Under the terms of the 2000 Plan, the option 
price  cannot  be  less  than  100%  of  the  fair  market  value  of  the  common  stock  at  the  date  
of grant.

In 2002, the Board of Directors approved the 2002 Stock Award and Incentive Plan (2002 Plan) 
that allows for the granting of incentive and non-qualified options, as well as other securities, 
to Company employees who are not subject to the reporting requirements of Section 16 of the 

I N T E R D I G I TA L  2 0 0 8   A R   95

Securities Act of 1934 or an “affiliate” for purposes of Rule 144 of the Securities Act of 1933. The 
2002 Plan authorizes the offer and sale of up to 1.5 million shares of common stock. The Board 
of  Directors  or  the  Compensation  Committee  of  the  Board  determines  the  number  of  options 
to be granted. Under all of these plans, options are generally exercisable for a period of 10 years 
from the date of grant and may vest on the grant date, another specified date or over a period 
of time. However, under plans that provide for both incentive and non-qualified stock options, 
grants most commonly vest in six semi-annual installments.

Information  with  respect  to  current  year  stock  options  activity  under  the  above  plans  is

* We currently have approximately 225,000 options outstanding that have an indefinite contractual life. These options were granted between 
1983 and 1986 under a pre-existing plan. For purposes of this table, these options were assigned an original life in excess of 50 years. The 
majority of these options have an exercise price between $8.25 and $11.63.

The total intrinsic value of stock options exercised during the years ended December 31, 2008, 
2007 and 2006 was $4.9 million, $14.2 million and $59.4 million, respectively. The total intrinsic 
value of our options outstanding at December 31, 2008 was $41.2 million. In 2008, we recorded 
cash received from the exercise of options of $2.2 million and tax benefits of $1.5 million. Upon 
option exercise, we issued new shares of stock.

At  December  31,  2008  and  2007,  we  had  approximately  2.9  million  options  outstanding  that 
had  exercise  prices  less  than  the  fair  market  value  of  our  stock  at  each  balance  sheet  date. 
These  options  would  have  generated  cash  proceeds  to  the  Company  of  $38.9  million  and  
$33.1 million, respectively, if they had been fully exercised on those dates.

Restricted Stock

Under our 1999 Restricted Stock Plan, as amended (1999 Plan), we may issue up to 3.5 million 
shares  of  restricted  common  stock  and  restricted  stock  units  (RSUs)  to  directors,  employees, 
consultants  and  advisors. The  restrictions  on  issued  shares  lapse  over  periods  generally 
ranging  from  1  to  5  years  from  the  date  of  the  grant. As  of  December  31,  2008  and  2007,  we 
had  issued  approximately  2.7  million  and  2.9  million  shares,  respectively,  of  restricted  stock 
and  RSUs  under  the  1999  Plan. The  related  compensation  expense  is  amortized  over  vesting 
periods  that  are  generally  from  1  to  5  years.  At  December  31,  2008  and  2007,  we  had 
unrecognized  compensation  cost  related  to  share-based  awards  of  $2.8  million  and  $5.6 
million, respectively. We expect to amortize the unrecognized compensation cost at December 
31, 2008 over a weighted average period of less than one year using an accelerated method.

We  grant  RSUs  as  an  element  of  compensation  to  all  of  our  employees. These  awards  vest 
over three years according to the following schedules:

Time-Based Awards

Employees below manager level  
  (represents 100% of the total award) 

Managers and technical equivalents 
  (represents 75% of the total award) 

Senior officers (represents 50% of the total award)

Vesting of performance-based RSU awards is subject to attainment of specific goals previously 
established  by  the  Compensation  Committee  of  the  Board  of  Directors.  Depending  upon 
performance  against  these  goals,  the  payout  range  could  be  anywhere  from  0  to  3  times  the 
values shown under Year 3 of the performance-based awards section above.

 **   The number of RSUs presented as granted in 2007 includes approximately 0.4 million performance RSUs which may be satisfied with 
between 0 and 0.4 million shares of common stock on January 1, 2010, depending upon the company’s performance against operating 
measures between the grant and end date for RSU Cycle 3. The number of RSUs presented as granted in 2008 includes an immaterial 
number of performance RSUs. As such, the number of performance RSUs issued during the two year period ending December 31, 2008 
remains at approximately 0.4 million.

The total vest date fair value of our RSUs that vested during each of 2008, 2007 and 2006 was 
$9.1 million, $6.4 million and $7.0 million, respectively.

Compensation Programs

We use a variety of compensation programs to attract and retain employees, as well as more 
closely  align  employee  compensation  with  Company  performance. These  programs  include 
both  cash  components  and  share-based  components. We  issue  new  shares  of  our  common 
stock to satisfy our obligations under the share-based components of these programs from the 
Common  Stock  and  Restricted  Stock  Plans  discussed  above.  However,  our  board  of  directors 
has  the  right  to  authorize  the  issuance  of  treasury  shares  to  satisfy  such  obligations  in  the 
future. We  recognized  $17.2  million,  $3.9  million  and  $3.5  million  of  compensation  expense  in 
2008,  2007  and  2006,  respectively,  related  to  a  performance-based  cash  incentive  under  our 
LTCP, discussed below. The 2008 amount includes a fourth quarter 2008 charge of $9.4 million 
to increase our accrual for Cycle 2a from the previously estimated payout of 100% to the actual 
payout of 175%. The increase in the incentive payout was driven by the Company’s success in a 
number of key goals, including signing LG and Samsung, two of the top five cellular handset 
OEMs, to 3G licensing agreements. These licenses helped increase our share of the 3G market 
under  license  from  approximately  20%  to  approximately  50%,  and  drove  substantial  positive 
operating cash flow over the period. We also recognized share-based compensation expense of 
$5.1 million, $9.8 million and $7.0 million in 2008, 2007 and 2006, respectively. The majority of 
the  share-based  compensation  expense,  for  all  years,  related  to  RSU  awards  granted  to 
managers  under  our  LTCP.  In  2006,  share-based  compensation  expense  also  included  a  non-
recurring  charge  of  $1.0  million  to  correct  our  accounting  related  to  share-based  grants 
awarded to two non-employee, non-director consultants in 1998. We previously accounted for 
these non-employee grants similarly to share-based employee grants, using the intrinsic value 
method. The charge reflects the incremental cost that would have been recognized by correctly 
treating these grants as non-employee grants using the fair value method. The balance of the 
share-based compensation expense relates to the programs described below.

LTCP

The LTCP applies to all management personnel and includes a time-based RSU component, a 
performance-based RSU component and a performance-based cash incentive component. The 
LTCP was originally designed as three year cycles that overlap by one year. However, the first 
cycle under the program covered the period from April 1, 2004 through January 1, 2006 (Cycle 
1). The  second  cycle  originally  covered  the  period  from  January  1,  2005  through  January  1, 
2008 (Cycle 2). In second quarter 2005, the Compensation Committee of our Board of Directors 
amended  the  LTCP  to  revise  the  performance-based  cash  award  portion  of  Cycle  2  to  cover  a 
3-1/2  year  period  from  July  1,  2005  through  January  1,  2009  (Cycle  2a),  and  authorized  a 
pro-rated  interim  payment,  of  approximately  $0.9  million,  related  to  first  half  2005. The  third 
RSU cycle (RSU Cycle 3) began on January 1, 2007 and runs through January 1, 2010. The third 
performance-based  cash  award  cycle  (Cash  Cycle  3)  began  on  January  1,  2008  and  runs 
through  January  1,  2011. The  fourth  RSU  cycle  (RSU  Cycle  4)  began  on  January  1,  2009  and 
runs through January 1, 2012.

During 2006, fourteen members of our senior management voluntarily exchanged approximately 
56,000 Cycle 2 time-based RSUs for an equal number of Cycle 2 performance-based RSUs. The 
Company  ultimately  satisfied  these  performance-based  RSUs  in  early  2008  through  the 
issuance  of  approximately  11,000  shares,  based  upon  senior  management’s  performance 
against  specified  goals.  During  2006,  the  LTCP  was  amended  such  that,  beginning  with  the 
January  1,  2007  grant,  executives  now  receive  50%  of  their  RSU  grant  as  performance-based 
RSUs  and  50%  as  time-based.  Under  the  amendment,  the  Company’s  managers  now  receive 
25% of their RSU grant as performance-based RSUs and 75% as time-based.

Other RSU Grants

We  also  grant  RSUs  to  all  non-management  employees,  all  non-employee  board  members 
and, in special circumstances, management personnel outside of the LTCP. Grants of this type, 
awarded to management personnel, are in addition to any grants awarded through the LTCP.

401(k) and Profit Sharing

We  have  a  401(k)  plan  wherein  employees  can  elect  to  defer  compensation  based  on  federal 
limits. The  Company  matches  a  portion  of  employee  contributions.  At  its  discretion,  the 
Company may also make a profit sharing contribution to its employees’ 401(k) plans. In 2008, 
2007  and  2006,  we  issued  14,673,  13,963  and  24,084  shares  of  common  stock  to  satisfy  our 
accrued obligations from the prior years of $0.4 million, $0.5 million and $0.5 million related to 
our  profit  sharing  contribution  to  eligible  employees  under  our  Savings  and  Protection  Plan 
(Savings Plan).

Annual Bonus

We  have  a  performance-based  annual  bonus  plan  that  is  applicable  to  all  employees.  For 
awards  earned  in  the  years  1999  through  2007,  executive  officers  and  other  key  management 
personnel  were  paid  30%  of  their  bonus  in  shares  of  restricted  stock.  Receiving  a  portion  of 
their  annual  bonus  in  the  form  of  equity  served  to  more  closely  align  senior  management’s 
interest with those of our shareholders. These shares had full voting power, the right to receive 
dividends,  were  not  forfeitable,  but  were  restricted  as  to  their  transferability  for  a  two  year 
period. We  issued  27,166,  11,765  and  17,000  shares  of  restricted  stock  in  2008,  2007  and  2006, 
respectively, to satisfy our accrued obligations from the prior years of $0.5 million, $0.4 million 
and $0.4 million under the restricted stock portion of the annual bonus.

During  2008,  as  part  of  its  annual  review  of  executive  compensation,  the  Compensation 
Committee  determined  that  the  LTCP,  which  was  introduced  in  2004,  provides  an  effective 
method  for  all  management  level  employees  to  increase  their  equity  ownership  in  the 
Company. As a result, the Compensation Committee elected to amend the annual bonus plan 
as it relates to executive officers and other key management personnel, so that, beginning with 
annual bonus awards earned in 2008, payouts would be 100% cash based.

12.  sHaReH olDeR   RIgHTs  Plan

In December 1996, our Board of Directors (Board) declared a distribution under our Shareholder 
Rights  Plan  (Rights  Plan)  of  one  Right  (as  defined  in  the  Rights  Plan)  for  each  outstanding 
common  share  of  the  Company  to  shareholders  of  record  as  of  the  close  of  business  on 
January  3,  1997.  In  addition,  all  new  common  shares  issued  after  January  3,  1997  are 
accompanied  by  one  Right  for  each  common  share  issued.  On  December  15,  2006,  the 
Company  entered  into  the Amended  and  Restated  Rights Agreement  (Amended Agreement) 
dated as of December 15, 2006, between the Company and American Stock Transfer and Trust 
Company as Rights Agent, amending and restating the Rights Plan.

In addition to continuing the provisions of the Rights Plan as previously in effect, the Amended 
Agreement  (i)  implemented  a  regular  evaluation  thereof  by  a  committee  composed  of  non-
management  members  of  the  Board  who  have  been  determined  by  the  Board  to  be 
“Independent  Directors,”  (ii)  extended  the  term  of  the  Rights  Plan  to  December  15,  2016,  (iii) 
simplified the determination of the Stock Acquisition Date under the Amended Agreement, (iv) 
changed  the  Purchase  Price  (as  defined  in  the Amended Agreement)  from  $250  to  $200,  (v) 
changed the redemption price of a Right from $.01 to $.001, and (vi) made certain other minor 
or  conforming  changes  and  other  changes  to  reflect  current  requirements  under  the  federal 
securities laws.

I N T E R D I G I TA L  2 0 0 8   A R   99

Pursuant to the Rights Plan, as amended and restated by the Amended Agreement, each Right 
entitles  shareholders  to  buy  one-thousandth  of  a  share  of  Series  B  Junior  Participating 
Preferred Stock (Preferred Stock) at the Purchase Price of $200 per 1/1000th of a share, subject 
to adjustment. Ordinarily, the Rights will not be exercisable until (i) 10 business days after the 
earliest  of  any  of  the  following  events:  (A)  a  person,  entity  or  group  other  than  certain 
categories  of  shareholders  exempted  under  the  Rights  Plan  (collectively,  a  Person)  acquires 
beneficial  ownership  of  10%  or  more  of  the  Company’s  outstanding  common  shares,  (B)  a 
Person  publicly  commences  a  tender  or  exchange  offer  for  10%  or  more  of  the  Company’s 
outstanding common shares, or (C) a Person publicly announces an intention to acquire control 
over the Company and proposes to elect through a proxy or consent solicitation such a number 
of  directors  who,  if  elected,  would  outnumber  the  Independent  Directors  (as  defined  in  the 
Rights Plan) on the Board, or (ii) such later date as may be determined by action of a majority 
of  the  Independent  Directors  prior  to  the  occurrence  of  any  event  specified  in  (i)  above 
(Distribution  Date).  In  general,  following  the  Distribution  Date  and  in  the  event  that  the 
Company  enters  into  a  merger  or  other  business  combination  with  an Acquiring  Person  (as 
defined in the Rights Plan) and the Company is the surviving entity, each holder of a Right will 
have the right to receive, upon exercise, units of Preferred Stock (or, in certain circumstances, 
Company common shares, cash, property, or other securities of the Company) having a value 
equal to twice the exercise price of the Right, or if the Company is acquired in such a merger or 
other  business  combination,  each  holder  of  a  Right  will  have  the  right  to  receive  stock  of  the 
acquiring  entity  having  a  value  equal  to  twice  the  exercise  price  of  the  Right. The  Company 
reserves the right to redeem the Rights by majority action of its Independent Directors at any 
time prior to the date such Rights become exercisable.

Valuation Allowances and Net Operating Losses

Generally  accepted  accounting  principles  require  that  we  establish  a  valuation  allowance  for 
any portion of our deferred tax assets for which management believes it is more likely than not 
that we will be unable to utilize the asset to offset future taxes. We believe it is more likely than 
not  that  the  vast  majority  of  our  state  deferred  tax  assets  will  not  be  utilized  and  we  have 
therefore maintained a near full valuation allowance against our state deferred tax assets.

Under Internal Revenue Code Section 382, the utilization of a corporation’s NOL carryforwards 
is limited following a change in ownership (as defined by the Internal Revenue Code) of greater 
than 50% within a three-year period. If it is determined that prior equity transactions limit our 
NOL carryforwards, the annual limitation will be determined by multiplying the market value of 
the  Company  on  the  date  of  the  ownership  change  by  the  federal  long-term  tax-exempt  rate. 
Any  amount  exceeding  the  annual  limitation  may  be  carried  forward  to  future  years  for  the 
balance of the NOL carryforward period.

Uncertain Income Tax Positions

We  adopted  FIN  48,  on  January  1,  2007. As  a  result  of  the  implementation,  we  recognized  a 
$2.1 million increase to reserves for uncertain tax positions. This increase, related to federal tax 
credits, was accounted for as a reduction to retained earnings on the balance sheet. Including 
this  cumulative  effect  adjustment,  the  gross  amount  of  the  Company’s  unrecognized  tax 
benefits as of December 31, 2008, 2007 and January 1, 2007 was $4.4 million, $4.4 million and 
$6.2 million, respectively, that if recognized, would reduce the Company’s effective income tax 
rate in the period of recognition. The total amount of unrecognized tax benefits could increase 
or decrease within the next twelve months for a number of reasons including the expiration of 
statutes  of  limitations,  audit  settlements,  tax  examination  activities  and  the  recognition  and 
measurement considerations under FIN 48.

During 2007, we completed a tax study related to our research and development tax credits. As 
a  result  of  this  study,  we  reduced  the  gross  amount  of  the  related  research  and  development 
tax  credits  by  $3.0  million  in  third  quarter  2007  when  we  filed  our  2006  tax  return. This 
reduction resulted in additional income tax expense of approximately $1.5 million and reduced 
our related FIN 48 reserve by $1.5 million. During 2007, we also filed our 2006 tax return which 
resulted in a reduction in certain other gross tax benefits of $0.3 million with an equal reduction 
to  our  FIN  48  reserve. As  of  December  31,  2008,  our  FIN  48  reserve  is  $4.4  million,  excluding 
accrued  interest. We  do  not  expect  a  material  change  in  this  estimate  in  the  next  twelve 
months, although a change is possible.

The  following  is  a  roll  forward  of  our  total  gross  unrecognized  tax  benefits  for  the  fiscal  year

Our  policy  is  to  recognize  interest  and  or  penalties  related  to  income  tax  matters  in  income 
tax  expense.  In  addition  to  the  balance  of  unrecognized  tax  benefits  in  the  above  table,  we 
have  accrued  related  interest  of  $0.5  million  and  $0  million  as  of  December  31,  2008  and  
2007, respectively.

The  Company  and  its  subsidiaries  are  subject  to  US  federal  income  tax,  foreign  income  and 
withholding  taxes,  and  income  taxes  from  multiple  state  jurisdictions. The  majority  of  our 
federal and state tax returns from 1990 through 2006 is currently open and will not close until 
the  respective  statutes  of  limitations  have  expired. The  statutes  of  limitations  generally  expire 
three  years  following  the  filing  of  the  return  or  in  some  cases  three  years  following  the 
utilization or expiration of net operating loss carry forwards. The statute of limitations applicable 
to our open federal returns will expire between the current year and 2011.

Foreign Taxes

We  pay  foreign  source  withholding  taxes  on  patent  license  royalties  and  state  taxes  when 
applicable. We apply foreign source withholding tax payments against our U.S. federal income 
tax obligations to the extent we have foreign source income to support these credits. In 2008, 
2007  and  2006,  we  paid  $15.7  million,  $15.8  million  and  $28.5  million  in  foreign  source 
withholding taxes, respectively, and applied these payments as credits against our U.S. federal 
tax  obligation. At  December  31,  2007,  we  accrued  $15.7  million  of  foreign  source  withholding 
taxes  payable  associated  with  expected  royalty  payments  from  a  licensee  and  recorded 
corresponding  deferred  tax  assets  related  to  the  expected  foreign  tax  credits  that  will  result 
from  these  payments.  In  the  course  of  future  tax  planning,  should  we  identify  tax  saving 
opportunities that entail amending prior year returns in order to fully avail ourselves of foreign 
tax credits that we previously considered unavailable to us, we will recognize the benefit of the 
credits in the period in which they are both identified and quantified.

Between  1999  and  2005  we  paid  approximately  $30.7  million  of  foreign  taxes.  During  this 
period  we  were  in  a  net  operating  loss  position  for  U.S.  federal  income  tax  purposes  and 
elected  to  deduct  these  foreign  tax  payments  as  expenses  on  our  U.S.  federal  income  tax 
returns  rather  than  take  them  as  foreign  tax  credits. We  elected  this  strategy  because:  a)  we 
had no U.S. cash tax obligations at the time and b) net operating losses can be carried forward 
significantly  longer  than  foreign  tax  credits. We  utilized  most  of  our  net  operating  losses  in 
2006  and  began  to  generate  U.S.  cash  tax  obligations. At  that  time,  we  began  to  treat  our 
foreign tax payments as foreign tax credits on our U.S. federal income tax return.

We are currently evaluating the possibility of amending our U.S. federal income tax returns for 
the periods 1999 — 2005 to determine if we are able to take the foreign tax payments we made 
during  that  period  as  foreign  tax  credits  instead  of  deductions. The  process  to  amend  these 
returns is complicated including aggregating information that was not previously required and 
may  not  be  available  and  involves  tax  treaty  competent  authority  procedures  including  both 
U.S.  and  foreign  tax  authorities.  It  is  possible  that  we  may  be  unable  to  establish  a  basis  to 
support  amending  the  returns,  but  it  is  estimated  that  a  maximum  benefit  could  be  a  refund 
claim of approximately $20.0 million. We cannot yet predict the amount if any, of any potential 
refund. However, we anticipate being in a position to file amended returns within the next year, 
although it is possible that we could file amended returns later. No benefit has been recorded 
for this contingent gain.

Evaluation of Disclosure Controls and Procedures

The  Company’s  Chief  Executive  Officer  and  its  Chief  Financial  Officer,  with  the  assistance  of 
other  members  of  management,  have  evaluated  the  effectiveness  of  our  disclosure  controls 
and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act 
of  1934)  as  of  December  31,  2008.  Based  on  that  evaluation,  the  Chief  Executive  Officer  and 
Chief  Financial  Officer  have  concluded  that  our  disclosure  controls  and  procedures  were 
effective  in  their  design  to  ensure  that  the  information  required  to  be  disclosed  by  us  in  the 
reports that we file or submit under the Securities Exchange Act of 1934 is recorded, processed, 
summarized and reported within the time periods specified in the SEC’s rules and forms and to 
ensure that the information required to be disclosed by us in the reports that we file or submit 
under  the  Securities  and  Exchange  Act  of  1934  is  accumulated  and  communicated  to  our 
management, including our Chief Executive Officer and Chief Financial Officer, as appropriate 
to allow timely decisions regarding required disclosure.

Management’s Annual Report on Internal Control Over Financial Reporting

Management  is  responsible  for  establishing  and  maintaining  adequate  internal  control  over 
financial  reporting  as  defined  in  Rules  13a-15(f)  and  15d-15(f)  under  the  Securities  Exchange 
Act  of  1934. The  Company’s  internal  control  over  financial  reporting  is  a  process  designed  to 
provide reasonable assurance regarding the reliability of financial reporting and the preparation 
of financial statements for external purposes in accordance with accounting principles generally 
accepted  in  the  United  States  of America.  Internal  control  over  financial  reporting  includes 
those policies and procedures that:

•  Pertain to the maintenance of records that in reasonable detail accurately and fairly reflect the 

transactions and dispositions of the assets of the Company;

•  Provide  reasonable  assurance  that  transactions  are  recorded  as  necessary  to  permit 
preparation  of  financial  statements  in  accordance  with  accounting  principles  generally 
accepted in the United States of America, and that receipts and expenditures of the Company 
are  being  made  only  in  accordance  with  authorization  of  management  and  directors  of  the 
Company; and

•  Provide  reasonable  assurance  regarding  prevention  or  timely  detection  of  unauthorized 
acquisition,  use  or  disposition  of  the  Company’s  assets  that  could  have  a  material  effect  on 
the consolidated financial statements.

Management,  including  the  Chief  Executive  Officer  and  Chief  Financial  Officer,  assessed  the 
effectiveness of internal control over financial reporting as of December 31, 2008. Management 
based this assessment on criteria for effective internal control over financial reporting described 
in  “  Internal  Control—Integrated  Framework”  issued  by  the  Committee  of  Sponsoring 
Organizations  of  the Treadway  Commission.  Based  on  this  assessment,  management 
determined  that,  as  of  December  31,  2008,  the  Company  maintained  effective  internal  control 
over financial reporting at a reasonable assurance level.

The effectiveness of the Company’s internal control over financial reporting as of December 31, 
2008  has  been  audited  by  PricewaterhouseCoopers  LLP,  an  independent  registered  public 
accounting firm, as stated in their report that appears under Item 8 in this Annual Report.

control over financial reporting.

WHEREAS,  Samsung  and  ITC  are  parties  to  that  certain  Binding Terms  and  Conditions  for

   c.  [***]: Without limitation, subject to Sections 6 and 7, and without limiting Section 4(c), [***] 
a  2G  Licensed  Standard  or  a  3G  Licensed  Standard.  Except  as  specifically  set  forth  in  this 
Section  and  in  Section  [***],  nothing  shall  be  deemed  as  conferring,  by  implication, 
estoppel,  or  otherwise,  any  license,  right  [***],  express  or  implied,  under  any  patent  or 
intellectual  property  right  to  develop,  design,  make,  have  made,  use,  import,  offer  to  sell, 
sell, or otherwise distribute products [***].

   d.  Notwithstanding anything to the contrary, the licenses granted under Sections 1(a) and 1(b) 
exclude any license, express or implied, to develop, design, make, have made, use, import,

   c.  Finality: The  Parties  further  acknowledge  that  the  License  Fee  is  final,  irrevocable,  non-

credits, or withholdings (other than tax withholding to the extent expressly provided above) 
for any reason.

3. Termination and Remedies.

  a.  Notwithstanding anything to the contrary herein, in the event that Samsung breaches any 
of the payment obligations under this Agreement, and fails to cure such breach within [***] 
days (or with respect to the first installment of the License Fee, within [***] days) following 
written notice thereof from ITC, then ITC shall have the right, at its election either:

i.  to  enforce  the  terms  and  conditions  of  this  Agreement,  and  pursue  all  remedies 
available at law or equity, in which case (i) all remaining payments under this Agreement 
shall become immediately due and payable in full, (ii) all rights and duties of the Parties 
under this Agreement shall remain in effect, (iii) all unpaid amounts shall accrue interest 
at  a  rate  equal  to  [***],  and  (iv)  Samsung  shall  reimburse  ITC  for  any  and  all  costs 
incurred  by  ITC  (including  reasonable  attorneys’  fees)  in  order  to  collect  such  amounts 
due; alternatively

ii.  to terminate this Agreement, and pursue all remedies available at law or equity. In the 
event  this Agreement  is  terminated  prior  to  ITC’s  receipt  of  the  first  installment  of  the 
License Fee, (i) all licenses, rights [***] granted to Samsung and its Affiliates [***] and 
the Releases set forth in Sections 9(a) and (b) hereunder shall not take effect and shall 
be  null  and  void,  (ii)  the  Parties  may  thereafter  proceed  in  the  Lawsuits,  and  (iii) 
Samsung  will  not  oppose  any  request  by  InterDigital  to  lift  the  stays  in  the  Lawsuits, 
and  will  proceed  according  to  any  new  schedule  set  in  the  Lawsuits.  In  the  event  this 
Agreement is terminated following receipt by ITC of the first installment of the License 
Fee,  all  licenses,  rights  [***]  granted  to  Samsung  and  its  Affiliates  [***]  and  the 
Releases  set  forth  in  Sections  9(a)  and  (b)  hereunder  shall  immediately  terminate,  be 
null  and  void  and  shall  have  no  further  force  or  effect  from  and  after  the  date  of  such 
notice, provided that in such event Samsung shall be entitled to [***] to InterDigital or 
its Affiliates.

  b.  In  addition,  either  Party  may  terminate  this Agreement  prior  to  the  expiration  of  the  3G 
Term, upon [***] days prior written notice to the other Party, if the other Party is in breach 
of any of its material obligations other than those addressed in Section 3(a) above and the 
breach  is  not  cured  within  the  [***]  days  after  notice  is  received  by  the  other  Party.  Such 
“other  material  obligations”  shall  be  deemed  to  be  any  material  failure  to  comply  with 
[***] obligations. In the event of a termination of this Agreement by InterDigital under this 
Section  3(b),  Samsung  shall,  without  limiting  any  other  right  or  remedy  of  InterDigital  at 
law  or  in  equity,  immediately  pay  ITC  all  unpaid,  installments  of  the  License  Fee  and  any 
other amounts accruing hereunder (in each case, whether or not then due), and all rights, 
licenses [***] granted to Samsung and its Affiliates [***] hereunder shall terminate unless 
(i) within [***] after the notice of such termination is received by Samsung, [***], (ii) [***] 
InterDigital  and  its  Related  Parties  and  their  past  and  present  officers,  directors, 
shareholders, employees, and agents and their respective direct and indirect [***], and (iii) 
within [***] after the notice of such termination is received by Samsung, [***]. Further, any 
termination  or  expiration  of  this  Agreement  shall  not  prejudice  InterDigital’s  right  to 
conduct  a  final  audit  under  Section  23  herein.  In  the  event  of  a  termination  of  this

its Affiliates  shall  be  limited  on  a  going-forward  basis  to  sales  of  2G  Licensed  Products

Agreement,  including  without  limitation  the  proportion  not  deemed  covered  by  this 
Agreement described in this Section 7(b)(i) above.

  ii.  [***], InterDigital may assign its rights and obligations under this Agreement in whole or 
in part to any InterDigital Related Party. InterDigital or any of its Related Parties may also 
assign  all  of  its  rights  and  obligations  under  this  Agreement  (other  than  the  [***] 
obligations  and  the  releases  hereunder)  to  any  successor  in  interest  to  InterDigital  or 
such Related Party (whether by merger, asset sale or otherwise), provided that, (A) such 
successor shall assume all obligations of InterDigital hereunder and all rights, [***], and 
licenses  granted  by  InterDigital  to  Samsung  shall  survive  and  remain  in  full  force  and 
effect, and (B) the [***] and other rights granted hereunder to InterDigital or such Related 
Parties shall be limited on a going-forward basis to sales of products subject to the [***] 
set forth in Section 4(d) in an amount not to [***]. For example, [***].

 iii.  In the event of any assignment covered by this Section 7, the assigning Party will provide 

notice to the other Party within a reasonable time following the assignment.

iv.   Notwithstanding  anything  to  the  contrary  in  this  Section  7,  the  assignment  of  this 
Agreement  in  accordance  with  this  Section  7  shall  not  convey  a  release  to  the  assignee

Notwithstanding the foregoing, ITC shall deliver originals of invoices to Weil, Gotshal & Manges 
LLP, with copy by email to Samsung.

 To the extent any notice sent to Samsung is not delivered or is returned or rejected, notice to 
Weil, Gotshal & Manges LLP shall be deemed sufficient.

15.  Attorneys’  Fees  and  Costs.  The  Parties  shall  bear  their  own  respective  attorneys’  fees  and 

costs incurred on any and all matters related to the Term Sheet or this Agreement.

16.   No Waiver. The failure of either Party to assert a right hereunder or to insist upon compliance 
with  any  term  or  condition  of  this Agreement  shall  not  constitute  a  waiver  of  that  right  or 
excuse a similar subsequent failure to perform any such term or condition by the other Party.

17.   Severability.  If  any  one  or  more  of  the  provisions  contained  in  this Agreement  is  held 
invalid,  illegal  or  unenforceable  in  any  respect,  other  than  payment  obligations  set  forth 
herein, the validity, legality and enforceability of the remaining provisions contained herein 
shall  not  in  any  way  be  affected  or  impaired  thereby.  In  the  event  that  the  absence  of  the 
invalidated  provision(s)  adversely  affects  the  substantive  rights  of  the  Parties,  the  Parties 
shall  use  their  best  efforts  to  replace  the  invalid,  illegal  or  unenforceable  provision(s)  with 
valid, legal and enforceable provision(s) which, as much as legally possible, implement the 
purposes of this Agreement as originally written. To the extent permitted by applicable law, 
each  of  the  Parties  hereby  waives  any  provision  of  law  that  would  render  any  provision 
hereof prohibited or unenforceable in any respect.

18.  Construction.  In  the  event  of  a  dispute,  neither  Party  shall  be  entitled  to  claim  that  any 
provision  should  be  construed  against  the  other  Party  by  reason  of  the  fact  that  it  was 
drafted by the other Party.

19.  Entire Agreement. This  Agreement,  including  any  exhibits  hereto  and  the  letter  from 
InterDigital,  Inc.  dated  as  of  November  24,  2008,  constitutes  the  entire,  complete  and  final 
agreement  and  understanding  among  the  Parties  as  to  the  subjects  addressed  in  this 
document,  and  supersedes  all  prior  agreements  (including,  without  limitation,  the Term 
Sheet), understandings, discussions and other communications, if any, between the Parties 
with  respect  to  the  subject  matter  thereof,  whether  oral  or  written.  Notwithstanding 
anything  to  the  contrary  contained  herein,  any  obligations  under  any  non-disclosure  or 
non-use  agreement  arising  after  the  1996 Agreements  in  connection  with  any  technology 
development  or  evaluation,  collaboration,  joint  development  or  transfer,  or,  any  product 
initiatives  including  but  not  limited  to  any  actual  or  potential  product  development, 
purchases,  sales  or  other  transactions  involving  either  Party’s  goods  or  services  shall  NOT 
be  affected  by  this  provision. The  Parties  and  each  of  the  respective  signatories  represent 
and  warrant  to  the  other  Party  that  the  signatories  have  authority  to  enter  into  this 
Agreement and bind the respective Parties and each of their Affiliates.

20.  Governing Law/Jurisdiction. New York law (without regard to its choice of law and conflict 
of laws rules) governs this Agreement, and any disputes relating to this Agreement will be 
subject  to  the  exclusive  jurisdiction  of  the  United  States  District  Court  for  the  Southern 
District of New York. (In the event there is a lack of jurisdiction in the United States District 
Court  for  the  Southern  District  of  New York,  the  New York  State  Courts  in  Manhattan  shall 
assume  exclusive  jurisdiction.) The  foregoing  exclusive  jurisdiction  provision  does  not 
apply  to,  and  may  not  be  used  as  a  basis  for  requesting  a  stay,  dismissal,  termination  or 
transfer of, any claim relating to patent infringement that is brought in another jurisdiction.

21.  Related  Party  Performance.  Each  Party  shall  be  responsible  for  all  actions  required  of  its 
Related  Parties  hereunder  and  shall  be  liable  to  the  other  Party  for  any  adverse  action  or 
failure  to  perform  by  Related  Parties  of  the  first  Party  hereunder.  In  addition,  each  Party 
agrees that any entity that, directly or indirectly, that Controls or that owns more than fifty 

124       I N T E R D I G I TA L  2 0 0 8   A R

shall have the right to audit the same.  Each Party shall (and shall cause its Related Parties 
to)  keep  books  and  records  (including,  without  limitation,  electronic  files)  adequate  to 
accurately  determine  the  applicability  of  the Acquisition  limitations  in  the  definitions  of 
Affiliate, 2G Licensed Products, and 3G Licensed Products under this Agreement. The books 
and  records  shall  be  retained  for  at  least  five  (5)  years  after  the Acquisition  to  which  they 
relate. The  auditing  Party  shall  have  the  right  in  the  event  of  an  announcement  (or  other 
media release) of an Acquisition by the other Party or any of its Affiliates and following the 
end of the 3G Term, to inspect during regular business hours all relevant books and records 
of  such  other  Party  and  its  Related  Parties  at  a  single  location  on  seven  (7)  business  days 
prior  notice,  and  such  other  Party  and  its  Related  Parties  shall  fully  cooperate  therewith 
(including  without  limitation  by  making  available  such  personnel  as  are  reasonably 
necessary  to  interpret  such  books  and  records). The  auditing  Party  shall  conduct  the  audit 
using  an  independent  certified  public  accountant. All  information  obtained  through  such 
audit shall be held in confidence, except as necessary to enforce this Agreement.

24.  Representations  and Warranties. As  of  the  execution  and  delivery  of  this Agreement,  the 

Parties make the following representations and warranties:

a.  Each Party represents and warrants to the other Party that such Party or its Affiliates are 
the sole and lawful owners of all rights, title and interest in and to each and every claim

claims.

b.  Each  Party  represents  and  warrants  to  the  other  Party  that  (i)  the  person  signing  this

In the Matter of

CERTAIN 3G WIDEBAND CODE DIVISION 
MULTIPLE ACCESS (WCDMA) HANDSETS 
AND COMPONENTS THEREOF 

Investigation No. 337-TA-601

Joint Motion for Termination of the Investigation Based On A Settlement

Complainants  InterDigital  Communications,  LLC  and  InterDigital Technology  Corporation 
(collectively  “InterDigital”)  and  respondents  Samsung  Electronics  Co.,  Ltd.,  Samsung 
Electronics  America,  Inc.,  and  Samsung Telecommunications  America  LLC  (collectively 
“Samsung”) hereby move for issuance of an initial determination terminating this investigation 
based  on  a  settlement.  InterDigital  and  Samsung  have  reached  a  settlement  that  includes  an 
agreement to terminate this investigation. The terms of settlement are set forth in the attached 
Exhibit  (Exhibit  1). The  parties’  current  agreement  replaces  the  term  sheet  previously  agreed 
upon  by  the  parties. The  parties  state  that  there  are  no  other  agreements,  written  or  oral, 
express or implied, between them concerning the subject matter of this investigation.

Commission  policy  and  the  public  interest  generally  favor  settlements,  which  preserve 
resources  for  both  the  Commission  and  the  private  parties,  and  termination  based  on  a 
settlement agreement is routinely granted. See, e.g., Certain Equipment for Telecommunications

Amendment to Amended and Restated Employment Agreement

This AMENDMENT TO THE AMENDED AND  RESTATED  EMPLOYMENT AGREEMENT  is  made 
this  17th  day  of  November,  2008,  and  amends  the  Amended  and  Restated  Employment 
Agreement (the “Employment Agreement”), dated as of May 16, 2005, by and between William 
J.  Merritt  (the “Employee”)  and  InterDigital,  Inc.,  a  corporation  organized  and  existing  under 
the  laws  of  the  Commonwealth  of  Pennsylvania  (the “Company”),  and  is  entered  into  by  the 
Employee and the Company.

WHEREAS,  the  Company  and  the  Employee  desire  to  enter  into  certain  modifications  to  the 
Employment  Agreement  in  order  to  comply  with  certain  changes  in  the  federal  tax  rules 
regarding the treatment of “nonqualified deferred compensation” plans or arrangements; and

WHEREAS,  certain  provisions  of  the  Employment Agreement  may  be  treated  as  providing  for 
payments  that  are  in  the  nature  of “nonqualified  deferred  compensation,”  as  that  phrase  is 
used  for  purposes  of  Section  409A  of  the  Internal  Revenue  Code  of  1986,  as  amended  (the 
“Code”); and

WHEREAS,  the  Employment Agreement  may  be  amended  by  written  agreement  executed  by 
the Company and the Employee.

NOW, THEREFORE, in consideration of the mutual covenants and obligations contained herein, 
and intending to be legally bound herby, the Employee and the Company agree as follows:

138       I N T E R D I G I TA L  2 0 0 8   A R

1.  Section  5(d)  of  the  Employment Agreement  is  hereby  amended  by  the  addition  of  the 

following at the end thereof:

 “All  amounts  payable  as  a “tax  gross-up”  under  this  Section  5(d)  shall  be  paid  as  soon  as 
practicable following the determination of the amount required to be paid to the Employee, 
and in no event later than the end of the calendar year following the calendar year in which 
the Employee pays the taxes subject to the “gross-up” provision. The preceding sentence is 
intended to be consistent with the requirements for treatment of such payments as payable 
at a specified time for purposes of Code Section 409A, as such requirements are set forth in 
Treasury Regulation Section 1.409A-3(i)(1)(v).”

2.  Section  5(e)  of  the  Employment Agreement is hereby amended and restated in its entirety, 

to read:

 “(e)  Notwithstanding  anything  in  this Agreement  to  the  contrary,  in  the  event  any  amounts 
payable  to  the  Employee  by  reason  of  his  termination  of  employment  are  determined  to 
constitute  payments  of  “nonqualified  deferred  compensation”  as  that  term  is  used  for 
purposes  of  Section  409A  of  the  Internal  Revenue  Code  of  1986,  as  amended  (the “Code”), 
and  such  amounts  would,  but  for  this  Section  5(e),  be  payable  before  the  six  month 
anniversary  of  his  termination  of  employment,  then  payment  of  such  amounts  shall  be 
delayed until the first business day following such six month anniversary of the Employee’s 
termination  of  employment  to  the  extent  such  deferral  of  payment  is  required  to  comply 
with Code Section 409A(a)(2)(B)(i) (required delay in payment of deferred compensation for 
“specified employees” of publicly traded corporations).”

3.  Section  10.5(a)  of  the  Employment Agreement  is  hereby  amended  by  the  addition  of  the 

following at the end thereof:

 “Notwithstanding  anything  to  the  contrary  set  forth  in  this  Section  10.5(a),  Employee  shall 
not  be  considered  to  have  terminated  employment  for  Good  Reason  unless  the  following 
requirements have been satisfied:

(i) 

 The Employee must provide notice to the Company within ninety (90) days of the initial 
existence of the basis for his claim to have Good Reason to terminate his employment.

(ii)   The  Company  must  have  failed  to  remedy  the  condition  that  is  claimed  to  constitute 

Good Reason within thirty (30) days of receiving notice from the Employee.

(iii)   The  Employee’s  subsequent  termination  of  employment  must  actually  occur  no  more 
than two (2) years following the initial existence of the basis for his claim to have Good 
Reason to terminate his employment.”
