Forward-Looking Statements We believe that it is important to communicate our future expectations to our shareholders and to the public. This Annual Report contains forward-looking statements within the meaning of the Private Securities Litigation Reform Act of 1995, including, without limitation, statements about our future plans, objectives, and expectations under the headings “Item 1. Business” and “Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations.” Forward-looking statements include any statement that does not directly relate to any historical or current fact. When used in this Annual Report and in future filings by the Company with the Securities and Exchange Commission (“SEC”), the words or phrases “will likely result”, “management expects”, “we expect”, “will continue”, “is anticipated”, “estimated” or similar expressions are intended to identify such “forward-looking statements.” Readers are cautioned not to place undue reliance on such forward-looking statements, each of which speaks only as of the date made. Such statements are subject to certain risks and uncertainties that could cause actual results to differ materially from historical results and those presently anticipated or projected, including the risks and uncertainties set forth in this Annual Report under the heading “Item 1A. Risk Factors” and in our other periodic reports. Examples of such risks and uncertainties include general economic and business conditions, the outcome of litigation, unexpected changes in technologies and technological advances, reliance on our intellectual property, and the ability to obtain adequate financing in the future. We have no obligation to publicly release the results of any revisions that may be made to any forward-looking statements to reflect anticipated events or circumstances occurring after the date of such statements. Item 1. Business. PART I We are in the business of innovating fundamental wireless technologies and products. We have designed and developed proprietary radio frequency (“RF”) technologies and integrated circuits for use in wireless communication products. We have expended significant financial and other resources to research and develop our RF technologies and to obtain patent protection for those technologies in the United States of America (“U.S.”) and certain foreign jurisdictions. We believe certain patents protecting our proprietary technologies have been broadly infringed by others and therefore the primary focus of our business plan is the enforcement of our intellectual property rights through patent infringement litigation and licensing efforts. We currently have patent enforcement actions ongoing in various U.S. district courts against mobile handset providers and providers of smart televisions and other WiFi products and, in certain cases, their chip suppliers for the infringement of several of our RF patents. We have made significant investments in developing and protecting our technologies, the returns on which are dependent upon the generation of future revenues for realization. We spent the majority of 2021 supporting our current patent enforcement actions. We have two patent enforcement cases pending against Qualcomm in the Middle District of Florida. Both cases experienced trial delays in 2020 and 2021 as a result of the COVID-19 pandemic. We are currently awaiting a trial 3 date in the first of these cases, which is expected to be scheduled in 2022 pending the court’s rulings on a few outstanding pre-trial motions. The second case which is pending against Qualcomm and Apple has been stayed pending the outcome of the first case. In 2021, we entered into two patent settlement and licensing agreements as a result of patent enforcement actions initiated in the Western District of Texas in 2020. We have additional enforcement actions ongoing in Texas including against Intel Corporation (“Intel”) which is scheduled for trial in 2022. See “Legal Proceedings” in Note 12 to our consolidated financial statements included in Item 8 for a detailed description of our various patent enforcement actions. A significant portion of our litigation costs have been funded under a secured contingent payment arrangement with Brickell Key Investments, LP (“Brickell”), contingent arrangements with legal counsel, and various debt and equity financings. See “Liquidity and Capital Resources” included in Item 7 for a full discussion of our litigation funding arrangements and our equity and debt financings. Products and Licenses During 2021, we did not offer any products for sale, but rather focused exclusively on our patent enforcement and licensing efforts. This resulted in two licensees of our technologies in 2021 including Buffalo, Inc. (“Buffalo”) and Zyxel Communications Corporation (“Zyxel”). Each of these licenses resulted from a settlement and patent license agreement following initiation of patent enforcement actions by us. See “Revenue” in Note 3 to our consolidated financial statements included in Item 8 for additional details. RF Technologies Our RF technologies enable highly accurate transmission and reception of RF carriers at low power, thereby enabling extended battery life, and certain size, cost, performance, and packaging advantages. We believe the most significant hurdle to the licensing and/or sale of our technologies and related products is the widespread use of certain of our technologies in infringing products produced by companies with significantly greater financial, technical, sales, and marketing resources. We believe we can secure licensing agreements with unauthorized current users of one or more of our technologies, and therefore compete, based on a solid and defensible patent portfolio and the advantages enabled by our unique patent-protected technologies. Patents and Trademarks We consider our intellectual property, including patents, patent applications, trademarks, and trade secrets to be significant to our business plan. We have a program to file applications for and obtain patents, copyrights, and trademarks in the U.S. and in selected foreign countries where we believe filing for such protection is appropriate to establish and maintain our proprietary rights in our technology and products. As of December 31, 2021, we had approximately 81 active U.S. and foreign patents related to our RF technologies. In addition, we have a number of recently expired patents that we believe continue to have significant economic value as a result of our ability to assert past damages in our patent enforcement actions. We estimate the economic lives of our patents to be the shorter of fifteen years from issuance or twenty years from the earliest application date. Our current portfolio of issued patents have expirations ranging from 2022 to 2036. 4 Employees As of December 31, 2021, we had seven full-time employees and one part-time employee. We also outsource certain specialty services, such as information technology, and utilize contract staff and third-party consultants from time to time to supplement our workforce. Our employees are not represented by any collective bargaining agreements and we consider our employee relations to be satisfactory. We have taken measures to protect our workforce in response to the COVID-19 pandemic, including optional remote worksites for all of our employees beginning in April 2020. Our management, with the oversight of our board of directors, monitors the hiring, retention and management of our employees. Available Information and Access to Reports We file annual reports on Forms 10-K, quarterly reports on Forms 10-Q, proxy statements and other reports, including any amendments thereto, electronically with the SEC. The SEC maintains an Internet site (http://www.sec.gov) where these reports may be obtained at no charge. We also make copies of these reports available, free of charge through our website (http://www.parkervision.com) via the link “SEC filings” as soon as practicable after filing or furnishing such materials with the SEC.

Item 1A. Risk Factors. In addition to other risks and uncertainties described in this Annual Report, the following risk factors should be carefully considered in evaluating our business because such factors may have a significant impact on our business, operating results, liquidity and financial condition. As a result of the risk factors set forth below, actual results could differ materially from those projected in any forward-looking statements. Our financial condition raises substantial doubt as to our ability to continue as a going concern. Financial and Operating Risks We have had significant losses and negative cash flows in every year since inception, and continue to have an accumulated deficit which, at December 31, 2021, was approximately $433.4 million. Our net losses for the years ended December 31, 2021 and 2020 were approximately $12.3 million and $19.6 million, respectively. Our independent registered public accounting firm has included in their audit opinion on our consolidated financial statements as of and for the year ended December 31, 2021, a 5 statement with respect to substantial doubt about our ability to continue as a going concern. Note 2 to our consolidated financial statements included in Item 8 includes a discussion regarding our liquidity and our ability to continue as a going concern. Our consolidated financial statements have been prepared assuming we will continue to operate as a going concern, which contemplates the realization of assets and the satisfaction of liabilities in the normal course of business. If we become unable to continue as a going concern, we may have to liquidate our assets and the values we receive for our assets in liquidation or dissolution could be significantly lower than the values reflected in our consolidated financial statements. The substantial doubt as to our ability to continue as a going concern may adversely affect our ability to negotiate reasonable terms with our vendors and may adversely affect our ability to raise additional capital in the future. We have had a history of losses which may ultimately compromise our ability to implement our business plan and continue in operation. To date, our technologies and products have not produced revenues sufficient to cover our operating costs. We will continue to make expenditures on patent protection and enforcement and general operations in order to continue our current patent enforcement and licensing efforts. Those efforts may not produce a successful financial outcome in 2022, or at all. Without a successful financial outcome from one or more of our patent enforcement and licensing efforts, we will not achieve profitability. Furthermore, our current capital resources are not sufficient to sustain our operations through 2022. If we are not able to generate sufficient revenues or obtain sufficient capital resources, we may not be able to implement our business plan or meet our current obligations due within the twelve months after the issuance date of our consolidated financial statements and investors will suffer a loss in their investment. This may also result in a change in our business strategies. We will need to raise substantial additional capital in the future to fund our operations. Failure to raise such additional capital may prevent us from implementing our business plan as currently formulated. Because we have had net losses and, to date, have not generated positive cash flow from operations, we have funded our operating losses primarily from the sale of debt and equity securities, including our secured and unsecured contingent debt obligations. Our capital resources include cash and cash equivalents of $1.0 million at December 31, 2021. Our business plan will continue to require expenditures for patent protection and enforcement and general operations. For the years ended December 31, 2021 and 2020, we used $7.7 million and $4.8 million, respectively in cash for operations which was funded primarily through the sale of convertible debt and equity securities. Our current capital resources will not be sufficient to meet our working capital needs for the twelve months after the issuance of our consolidated financial statements and we will require additional capital to fund our operations. Additional capital may be in the form of debt securities, the sale of equity securities, including common or preferred stock, additional litigation funding, or a combination thereof. Failure to raise additional capital may have a material adverse impact on our ability to achieve our business objectives. Raising additional capital by issuing debt securities or additional equity securities may result in dilution and/or impose covenants or restrictions that create operational limitations or other obligations. We will require additional capital to fund our operations and meet our current obligations due within the twelve months after the issuance date of our consolidated financial statements. Financing, if any, may be in the form of debt or sales of equity securities, including common or preferred stock. Debt instruments or the sale of preferred stock may result in the imposition of operational limitations and other covenants and payment obligations, any of which may be burdensome to us and may have a material adverse impact 6 on our ability to implement our business plan as currently formulated. The sale of equity securities, including common or preferred stock, may result in dilution to the current stockholders’ ownership and may be limited by the number of shares we have authorized and available for issuance. We may be obligated to repay outstanding notes at a premium upon the occurrence of an event of default. We have $2.9 million in outstanding principal under convertible notes at December 31, 2021. If we fail to comply with the various covenants set forth in each of the notes, including failure to pay principal or interest when due or, under certain notes, consummating a change in control, we could be in default thereunder. Upon an event of default under each of the notes, the interest rate of the notes will increase to 12% per annum and the outstanding principal balance of the notes plus all accrued unpaid interest may be declared immediately payable by the holders. We may not have sufficient available funds to repay the notes upon an event of default, and we cannot provide assurances that we will be able to obtain other financing at terms acceptable to us, or at all. Our ability to utilize our tax benefits could be substantially limited if we fail to generate sufficient income or if we experience an “ownership change.” We have cumulative net operating loss carryforwards (“NOLs”) totaling approximately $313.2 million at December 31, 2021, of which $276.6 million is subject to expiration in varying amounts from 2022 to 2037. Our ability to fully recognize the benefits from those NOLs is dependent upon our ability to generate sufficient income prior to their expiration. In addition, our NOL carryforwards may be limited if we experience an ownership change as defined by Section 382 of the Internal Revenue Code (“Section 382”). In general, an ownership change under Section 382 occurs if 5% shareholders increase their collective ownership of the aggregate amount of our outstanding shares by more than 50 percentage points over a relevant lookback period. We have sold a significant number of equity securities over the relevant lookback period which increases the risk of triggering an ownership change under Section 382 from the future sale of additional equity securities. An ownership change under Section 382 will significantly limit our ability to utilize our tax benefits. Our litigation funding arrangements may impair our ability to obtain future financing and/or generate sufficient cash flows to support our future operations. We have funded much of our cost of litigation through contingent financing arrangements with Brickell Key Investments LP (“Brickell”) and others and contingent fee arrangements with legal counsel. The repayment obligation to Brickell is secured by the majority of our assets until such time that we have repaid a specified minimum return. Furthermore, our contingent arrangements will result in reductions in the amount of net proceeds retained by us from litigation, licensing and other patent-related activities. The contingent fees payable to legal counsel, Brickell and others will consume all of our initial future proceeds up to specified limits and could exceed half of our proceeds thereafter depending on size and timing of proceeds, among other factors. The long-term continuation of our business plan is dependent upon our ability to secure sufficient financing to support our business, and our ability to generate revenues and/or patent related proceeds sufficient to offset expenses and meet our contingent payment obligations. Failure to generate revenue or other patent-related proceeds sufficient to repay our contingent obligations may impede our ability to obtain additional financing which will have a material adverse effect on our ability to achieve our long-term business objectives. 7 Our litigation can be time-consuming, costly and we cannot anticipate the results. Since 2011, we have spent a significant amount of our financial and management resources to pursue patent infringement litigation against third parties. We believe this litigation, and other litigation matters that we may in the future determine to pursue, will continue to consume management and financial resources for long periods of time. There can be no assurance that our current or future litigation matters will ultimately result in a favorable outcome for us or that our financial resources will not be exhausted before achieving a favorable outcome. In addition, even if we obtain favorable interim rulings or verdicts in particular litigation matters, they may not be predictive of the ultimate resolution of the matter. Unfavorable outcomes could result in exhaustion of our financial resources and could hinder our ability to pursue licensing and/or product opportunities for our technologies in the future. Failure to achieve favorable outcomes from one or more of our patent enforcement actions will have a material adverse impact on our financial condition, results of operations, cash flows, and business prospects. If our patents and intellectual property rights do not provide us with the anticipated market protections, our competitive position, business, and prospects will be impaired. We rely on our intellectual property rights, including patents and patent applications, to provide competitive advantage and protect us from theft of our intellectual property. We believe that our patents are for entirely new technologies and that our patents are valid, enforceable and valuable. However, third parties have made claims of invalidity with respect to certain of our patents and other similar claims may be brought in the future. For example, in 2019, the Federal Patent Court in Munich invalidated one of our patents that was the subject of infringement cases against LG and Apple in Germany following a nullity action filed by Qualcomm. If our patents are shown not to be as broad as currently believed or are otherwise challenged such that some or all of the protection is lost, we will suffer adverse effects from the loss of competitive advantage and our ability to offer unique products and technologies. As a result, there would be an adverse impact on our financial condition and business prospects. Furthermore, defending against challenges to our patents may give rise to material costs for defense and divert resources away from our other activities. Our business, results of operations, and financial condition may be impacted by the recent coronavirus (COVID-19) outbreak. The global spread of COVID-19 has created significant volatility and uncertainty in financial markets. If such volatility and uncertainty persist, we may be unable to raise additional capital on terms that are acceptable to us, or at all. Additionally, in response to the pandemic, governments and the private sector have taken a number of drastic measures to contain the spread of COVID-19. While our employees currently have the ability and are encouraged to work remotely, such measures may have a substantial impact on employee attendance or productivity, which, along with the possibility of employees’ illness, may adversely affect our operations. In addition, COVID-19 has negatively impacted the timing of our current patent infringement actions as a result of office closures, travel restrictions and court closures. For example, our patent infringement trial in Orlando, Florida has been delayed twice due to the impact of COVID-19. It is possible that further delays in our cases could occur. Although COVID-19 is currently not material to our results of operations, there is significant uncertainty relating to the potential impact of COVID-19 on our business. The extent to which COVID-19 impacts our ongoing patent enforcement actions and our ability to obtain financing, as well as our results of operations and financial condition, generally, will depend on future developments which are highly uncertain and cannot be predicted, including new information which may emerge concerning the severity 8 of COVID-19 and the actions taken by governments and private businesses to contain COVID-19 or treat its impact, among others. If the disruptions posed by COVID-19 continue for an extensive period of time, our business, results of operations, and financial condition may be materially adversely affected. We are subject to outside influences beyond our control, including new legislation that could adversely affect our licensing and enforcement activities and have an adverse impact on the execution of our business plan. Our licensing and enforcement activities are subject to numerous risks from outside influences, including new legislation, regulations and rules related to obtaining or enforcing patents. For instance, the U.S. has enacted sweeping changes to the U.S. patent system including changes that transition the U.S. from a “first-to-invent” to a “first-to-file” system and that alter the processes for challenging issued patents. To the extent that we are unable to secure patent protection for our future technologies and/or our current patents are challenged such that some or all of our protection is lost, we will suffer adverse effects to our ability to offer unique products and technologies. As a result, there would be an adverse impact on our financial position, results of operations and cash flows and our ability to execute our business plan. Our industry is subject to rapid technological changes which if we are unable to match or surpass, will result in a loss of competitive advantage and market opportunity. Because of the rapid technological development that regularly occurs in the wireless technology industry, along with shifting user needs and the introduction of competing products and services, we have historically devoted substantial resources to developing and improving our technology and introducing new product offerings. As a result of our limited financial resources, we have ceased our research and development activities which could result in a loss of future market opportunity which could adversely affect our future revenue potential. We are highly dependent on Mr. Jeffrey Parker as our chief executive officer. If his services were lost, it would have an adverse impact on the execution of our business plan. Because of Mr. Parker’s leadership position in the Company, the relationships he has garnered in both the industry in which we operate and the investment community and the key role he plays in our patent litigation strategies, the loss of his services might be seen as an impediment to the execution of our business plan. If Mr. Parker was no longer available to the Company, investors might experience an adverse impact on their investment. We maintain $5 million in key-employee life insurance for our benefit for Mr. Parker. If we are unable to retain key highly skilled employees, we will not be able to execute our current business plans. Our business is dependent on having skilled and specialized key employees to conduct our business activities. The inability to retain these key employees would have an adverse impact on the technical support activities and the financial reporting and regulatory compliance activities that our business requires. These activities are instrumental to the successful execution of our business plan. 9 Any disruptions to our information technology systems or breaches of our network security could interrupt our operations, compromise our reputation, and expose us to litigation, government enforcement actions, and costly response measures and could have a material adverse effect on our business, financial condition and results of operations. We rely on information technology systems, including third-party hosted servers and cloud-based servers, to keep business, financial, and corporate records, communicate internally and externally, and operate other critical functions. If any of our internal systems or the systems of our third-party providers are compromised due to computer virus, unauthorized access, malware, and the like, then sensitive documents could be exposed or deleted, and our ability to conduct business could be impaired. Cyber incidents can result from deliberate attacks or unintentional events. These incidents can include, but are not limited to, unauthorized access to our systems, computer viruses or other malicious code, denial of service attacks, malware, ransomware, phishing, SQL injection attacks, human error, or other events that result in security breaches or give rise to the manipulation or loss of sensitive information or assets. Cyber incidents can be caused by various persons or groups, including disgruntled employees and vendors, activists, organized crime groups, and state-sponsored and individual hackers. Cyber incidents can also be caused or aggravated by natural events, such as earthquakes, floods, fires, power loss, and telecommunications failures. The risk of cybersecurity breach has generally increased as the number, intensity, and sophistication of attempted attacks from around the world has increased. While we have cyber security procedures in place, given the evolving nature of these threats, there can be no assurance that we will not suffer material losses in the future due to cyber-attacks. To date, we have not experienced any material losses relating to cyber-attacks, computer viruses or other systems failures. Although we have taken steps to protect the security of data maintained in our information systems, it is possible that our security measures will not be able to prevent the systems’ improper functioning or the improper disclosure of personally identifiable information, such as in the event of cyber- attacks. In addition to operational and business consequences, if our cybersecurity is breached, we could be held liable to our customers or other parties in regulatory or other actions, and we may be exposed to reputation damages and loss of trust and business. This could result in costly investigations and litigation, civil or criminal penalties, fines and negative publicity. Risks Relating to our Common Stock Our outstanding options and warrants may affect the market price and liquidity of the common stock. At December 31, 2021, we had 77.0 million shares of common stock outstanding and had outstanding options and warrants for the purchase of up to 33.6 million additional shares of common stock, of which approximately 27.0 million were exercisable as of December 31, 2021. In addition, as described more fully below, holders of convertible notes may elect to receive a substantial number of shares of common stock upon conversion of the notes and we may elect to pay accrued interest on the notes in shares of our common stock. All of the shares of common stock underlying these securities are currently registered for sale to the holder or for public resale by the holder. The amount of common stock reserved for issuance may have an adverse impact on our ability to raise capital and may affect the price and liquidity of our common stock in the public market. In addition, the issuance of these shares of common stock will have a dilutive effect on current stockholders’ ownership. 10 The conversion of outstanding convertible notes into shares of common stock, and the issuance of common stock by us as payment of accrued interest upon the convertible notes, could materially dilute our current stockholders. We have an aggregate principal amount of $2.9 million in convertible notes outstanding at December 31, 2021. The notes are convertible into shares of our common stock at fixed conversion prices, which may be less than the market price of our common stock at the time of conversion. If the entire principal were converted into shares of common stock, we would be required to issue an aggregate of up to 20.2 million shares of common stock. If we issue all of these shares, the ownership of our current stockholders will be diluted. Further, we may elect to pay interest on the notes, at our option, in shares of common stock, at a price equal to the then-market price for our common stock. As of December 31, 2021, we have issued approximately 2.7 million shares of common stock as in-kind interest payments on our convertible notes. We currently do not believe that we will have the financial ability to make payments on the notes in cash when due. Accordingly, we currently intend to make such payments in shares of our common stock to the greatest extent possible. Such interest payments could further dilute our current stockholders. The price of our common stock may be subject to substantial volatility. The trading price of our common stock has been and may continue to be volatile. Between January 1, 2020 and March 15, 2022, the reported high and low sales prices for our common stock ranged between $0.15 and $1.91 per share. The price of our common stock may continue to be volatile as a result of a number of factors, some of which are beyond our control. These factors include, but are not limited to, developments in outstanding litigation, our performance and prospects, general conditions of the markets in which we compete, economic and financial conditions, and the impact of COVID-19 on global financial markets. Such volatility could materially and adversely affect the market price of our common stock in future periods. Our common stock is quoted on OTCQB, an over-the-counter market. There can be no assurance that our common stock will continue to trade on the OTCQB or on another over-the-counter market or securities exchange. Our common stock began trading on the OTCQB, an over-the-counter market, in August 2018 immediately following delisting from Nasdaq, under the symbol “PRKR”. The over-the-counter market is a significantly more limited market than a nationally-recognized securities exchange such as Nasdaq, and the quotation of our common stock on the over-the-counter market has resulted in a less liquid market available for existing and potential stockholders to trade shares of our common stock. Securities traded in the over-the-counter market generally have less liquidity due to factors such as the reduced number of investors that will consider investing in the securities, the reduced number of market makers in the securities, and the reduced number of securities analysts that follow such securities. As a result, holders of shares of our common stock may find it difficult to resell their shares at prices quoted in the market or at all. We are also subject to additional compliance requirements under applicable state laws relating to the issuance of our securities. This could have a long-term adverse effect on our ability to raise capital, which ultimately could adversely affect the market price of our common stock. We cannot provide any assurances as to if or when we will be in a position to relist our common stock on a nationally-recognized securities exchange. 11 Our common stock is classified as a “penny stock” under SEC rules, which means broker-dealers who make a market in our stock will be subject to additional compliance requirements. Our common stock is deemed to be a "penny stock" as defined in the Securities Exchange Act of 1934 (the “Exchange Act”). Penny stocks are stocks (i) with a price of less than five dollars per share; (ii) that are not traded on a recognized national exchange; (iii) whose prices are not quoted on an automated quotation system sponsored by a recognized national securities association; or (iv) whose issuer has net tangible assets less than $2,000,000 (if the issuer has been in continuous operation for at least three years); or $5,000,000 (if continuous operations for less than three years); or with average revenues of less than $6,000,000 for the last three years. The Exchange Act requires broker-dealers dealing in penny stocks to provide potential investors with a document disclosing the risks of penny stocks and to obtain a manually signed and dated written receipt of the document before effecting any transaction in a penny stock for the investor’s account. Potential investors in our common stock are urged to obtain and read such disclosure carefully before purchasing any shares that are deemed to be “penny stock.” Further, the Exchange Act requires broker-dealers dealing in penny stocks to approve the account of any investor for transactions in such stocks before selling any penny stock to that investor. These procedures require the broker-dealer to (i) obtain from the investor information concerning his, her or its financial situation, investment experience and investment objectives; (ii) reasonably determine, based on that information, that transactions in penny stocks are suitable for the investor, and that the investor has sufficient knowledge and experience as to be reasonably capable of evaluating the risks of penny stock transactions; (iii) provide the investor with a written statement setting forth the basis on which the broker dealer made the determination in (ii) above; and (iv) receive a signed and dated copy of such statement from the investor, confirming that it accurately reflects the investor’s financial situation, investment experience and investment objectives. Compliance with these requirements may affect the ability or willingness of broker-dealers to sell our securities, and accordingly would affect the ability of stockholders to sell their securities in the public market. These additional procedures could also limit our ability to raise additional capital in the future. We do not currently pay dividends on our common stock and thus stockholders must look to appreciation of our common stock to realize a gain on their investments. We do not currently pay dividends on our common stock and intend to retain our cash and future earnings, if any, to fund our business plan. Our future dividend policy is within the discretion of our board of directors and will depend upon various factors, including our business, financial condition, results of operations and capital requirements. We therefore cannot offer any assurance that our board of directors will determine to pay special or regular dividends in the future. Accordingly, unless our board of directors determines to pay dividends, stockholders will be required to look to appreciation of our common stock to realize a gain on their investment. There can be no assurance that this appreciation will occur. Provisions in our certificate of incorporation and by-laws could have effects that conflict with the interest of shareholders. Some provisions in our certificate of incorporation and by-laws could make it more difficult for a third party to acquire control of us. For example, our board of directors is divided into three classes with directors having staggered terms of office, our board of directors has the ability to issue preferred stock without shareholder approval, and there are advance notification provisions for director nominations and submissions of proposals from shareholders to a vote by all the shareholders under the by-laws. Florida law also has anti-takeover provisions in its corporate statute. 12 We have a shareholder protection rights plan that may delay or discourage someone from making an offer to purchase the Company without prior consultation with the board of directors and management, which may conflict with the interests of some of the shareholders. On November 17, 2005, as amended on November 20, 2015 and November 20, 2020, our board of directors adopted a shareholder protection rights plan which called for the issuance, on November 29, 2005, as a dividend, of rights to acquire fractional shares of preferred stock. The rights are attached to the shares of common stock and transfer with them. In the future, the rights may become exchangeable for shares of preferred stock with various provisions that may discourage a takeover bid. Additionally, the rights have what are known as “flip-in” and “flip-over” provisions that could make any acquisition of the Company more costly. The principal objective of the plan is to cause someone interested in acquiring the Company to negotiate with the board of directors rather than launch an unsolicited bid. This plan may limit, prevent, or discourage a takeover offer that some shareholders may find more advantageous than a negotiated transaction. A negotiated transaction may not be in the best interests of the shareholders. Item 1B. Unresolved Staff Comments. Not applicable. Item 2. Properties. Until the expiration of our lease in October 2020, our headquarters were located in a 3,000 square foot leased facility in Jacksonville, Florida. Beginning in November 2020, we reverted to remote worksites for all of our employees in light of the pandemic. We believe a remote work environment is currently suitable for the conduct of our business. We have an additional 7,000 square foot leased facility in Lake Mary, Florida that was primarily for engineering design activities. We have ceased use of the Lake Mary facility and secured a sublease tenant in 2021 for the duration of the lease term through November 2022. Refer to Note 8 to our consolidated financial statements included in Item 8 for information regarding our outstanding lease obligations. Item 3. Legal Proceedings. We are a party to a number of patent enforcement actions initiated by us against others for the infringement of our technologies, as well as proceedings brought by others against us in an attempt to invalidate certain of our patent claims. These patent-related proceedings are more fully described in Note 12 to our consolidated financial statements included in Item 8. Item 4. Mine Safety Disclosures. Not applicable. 13 PART II Item 5. Market for the Registrant’s Common Equity, Related Stockholder Matters and Issuer Purchases of Equity Securities. Market Information Our Common Stock is listed on the OTCQB, an over-the-counter market, under the ticker symbol “PRKR”. Over-the-counter market quotations reflect inter-dealer prices, without retail mark-up, mark-down, or commission, and may not necessarily represent actual transactions. Holders As of March 15, 2022, we had approximately 83 holders of record and we believe there are approximately 7,200 beneficial holders of our common stock. Dividends We do not currently pay dividends on our common stock and intend to retain our cash and future earnings, if any, to fund our business plan. The payment of cash dividends in the future will be dependent upon our revenue and earnings, if any, capital requirements and general financial condition. The payment of any dividends will be within the discretion of our board of directors. Purchases of Equity Securities by Issuer and Affiliated Purchasers No purchases of our equity securities have been made by us or affiliated purchasers within the fourth quarter of the fiscal year ended December 31, 2021. Item 6. [Reserved]. Item 7. Management's Discussion and Analysis of Financial Condition and Results of Operations. Executive Overview We are in the business of innovating fundamental wireless technologies and products. We have designed and developed proprietary RF technologies and integrated circuits based on those technologies, and we license our technologies to others for use in wireless communication products. We have expended significant financial and other resources to research and develop our RF technologies and to obtain patent protection for those technologies in the U.S. and certain foreign jurisdictions. We believe certain patents protecting our proprietary technologies have been broadly infringed by others and therefore our business plan primarily consists of enforcement of our intellectual property rights through patent infringement litigation and licensing efforts. We currently have patent enforcement actions ongoing in various U.S. district courts against providers of mobile handsets, smart televisions and other WiFi products and, in certain cases, their chip suppliers for the infringement of a number of our RF patents. We have made significant investments in developing and protecting our technologies, the returns on which are dependent upon the generation of future revenues for realization. 14 We continue to aggressively pursue licensing opportunities with wireless communications companies that make, use or sell chipsets and/or products that incorporate RF. We believe there are a number of wireless communications companies that can benefit from the use of the RF technologies we have developed, whether through a license or, in certain cases, a joint product venture that may include licensing rights. Our licensing efforts to date have required litigation in order to enforce and/or defend our intellectual property rights. Since 2011, we have been involved in patent infringement litigation against Qualcomm and others for the unauthorized use of our technology. Refer to Note 12 to our consolidated financial statements included in Item 8 for a complete discussion of our legal proceedings. We have expended significant resources since 2011 and incurred significant debt for the enforcement and defense of our intellectual property rights. Recent Developments On March 22, 2022, the United States District Court in the Middle District of Florida (Orlando Division) issued an order granting Qualcomm’s motion for summary judgment ruling that Qualcomm does not infringe the three patents that are the subject of our infringement case against them. This ruling, which is a final determination of the district court, follows a March 9, 2022 order granting a Qualcomm motion to strike and exclude the opinions of our experts regarding the alleged infringement and validity issues. We intend to appeal both of these decisions. Refer to ParkerVision v. Qualcomm (Middle District of Florida) included in Note 12 to our consolidated financial statements included in Item 8 for a complete discussion of these legal proceedings. In February 2022, our two patent infringement cases against Intel in the Western District of Texas were reconfigured whereby the first case would assert an aggregate of six patents against Intel cellular products and the second case would assert the same six patents along with a seventh patent against Intel WiFi and Bluetooth products. As a result of the restructuring of the cases, the trial date for the first Intel case was moved from June 2022 to October 24, 2022. In March 2022, as a result of discovery delays, the trial date was moved to a start date of December 5, 2022. The second case against Intel is currently scheduled for trial commencing in May 2023, however that date may change in lieu of the revised schedule in the first Intel case. Refer to ParkerVision v. Intel (Western District of Texas) and ParkerVision v. Intel II (Western District of Texas) included in Note 12 to our consolidated financial statements included in Item 8 for a complete discussion of these legal proceedings. In January 2022, the Patent Trial and Appeal Board (“PTAB”) issued its final decisions on two Inter Partes Reviews (“IPRs”) filed by Intel against two of the patents asserted in the ParkerVision v. Intel infringement cases. The PTAB ruled in our favor with respect to the seven challenged claims of one of the two patents and ruled in Intel’s favor with respect to the one challenged claim of the second patent. We have one additional IPR filed by Intel against a patent asserted in our second case, and the PTAB is expected to issue its final decision in July 2022. Refer to Intel v. ParkerVision (PTAB) included in Note 12 to our consolidated financial statements included in Item 8 for a complete discussion of these IPR proceedings. Liquidity and Capital Resources We have incurred significant losses from operations and negative cash flows in every year since inception, largely as a result of our significant investments in developing and protecting our intellectual property, and have utilized the proceeds from sales of debt and equity securities and contingent funding arrangements with third-parties to fund our operations, including the cost of litigation. For the year ended December 31, 2021, we incurred a net loss of approximately $12.3 million and negative cash flows from operations of approximately $7.7 million. At December 31, 2021, we had cash 15 and cash equivalents of approximately $1.0 million and an accumulated deficit of approximately $433.4 million. Additionally, a significant amount of future proceeds that we may receive from our patent enforcement and licensing programs will first be utilized to repay borrowings, legal fees and litigation expenses under our contingent funding arrangements. Our independent registered public accounting firm has included in their audit report an explanatory paragraph expressing substantial doubt about our ability to continue as a going concern. See Note 2 to our consolidated financial statements included in Item 8 for a discussion of our liquidity and our ability to continue as a going concern. We used cash for operations of approximately $7.7 million and $4.8 million for the years ended December 31, 2021 and 2020, respectively. The increase in cash used for operations from 2020 to 2021 is primarily due to the use of approximately $3.9 million in cash for the reduction of accounts payable and accrued expenses during the year ended December 31, 2021, as compared to a $1.8 million increase in accounts payable and accrued expenses during the year ended December 31, 2020. Our accounts payable decreased $3.6 million from December 31, 2020 to December 31, 2021 primarily as result of a $3.0 million payment to a law firm in settlement of our outstanding fees and expenses and in exchange for an agreed-upon reduction in potential success fees payable to the firm from future patent-related proceeds. This increase in use of cash from 2020 to 2021 was somewhat offset by a reduction in cash-based operating costs from 2020 to 2021, largely as a result of decreased litigation fees and expenses. As a result of the decrease in our current liabilities from 2020 to 2021, our working capital improved by approximately $3.7 million. For the year ended December 31, 2021, we received aggregate net proceeds from the sale of debt and equity securities, including the exercise of outstanding options and warrants, of approximately $7.2 million compared to approximately $7.6 million in proceeds received for the year ended December 31, 2020. We repaid approximately $0.1 million and $1.3 million, respectively in debt obligations during the years ended December 31, 2021 and 2020. Our ability to meet our short-term liquidity needs, including our debt repayment obligations, is dependent upon one or more of (i) our ability to successfully negotiate licensing agreements and/or settlements relating to the use of our technologies by others in excess of our contingent payment obligations to Brickell and legal counsel; and/or (ii) our ability to raise additional capital from the sale of debt or equity securities or other financing arrangements. Significant portions of our litigation costs to date have been funded by contingent payment arrangements with legal counsel. Fee discounts offered by legal counsel in exchange for contingent payments upon successful outcome in our litigation are not recognized in expense until such time that the related proceeds on which the contingent fees are payable are considered probable. Contingent fees vary based on each firm’s specific fee agreement. We currently have contingent fee arrangements in place for all of our active cases. In addition to our contingent fee agreements with legal counsel, we have secured and unsecured contingent payment obligations to litigation funders that have priority payments due from patent-related proceeds as discussed more fully under “Financial Condition-Contingent Payment Obligations” below. Although current working capital will not be used to repay our contingent arrangements, based on our current outstanding legal proceedings, funding arrangements and contingent payment arrangements, we estimate that up to 100% of our initial future proceeds will be used to repay contingent payment arrangements until the minimum return under our secured contingent payment obligation has been met. After repayment of minimum returns on litigation financing, we estimate that 45% to 68% of remaining future proceeds from current actions could be payable to others, depending on the proceeding and the nature, amount and timing of proceeds, among other factors. 16 Patent enforcement litigation is costly and time-consuming and the outcome is difficult to predict. We expect to continue to invest in the support of our patent enforcement and licensing programs. We expect that revenue generated from patent enforcement actions and/or technology licenses in 2022, if any, after deduction of contingent payment obligations, may not be sufficient to cover our operating expenses. In the event we do not generate revenues, or other patent-related proceeds, sufficient to cover our operational costs and contingent repayment obligations, we will be required to raise additional working capital through the sale of debt or equity securities or other financing arrangements. The long-term continuation of our business plan is dependent upon our ability to secure sufficient financing to support our business, and our ability to generate revenues and/or patent-related proceeds sufficient to offset expenses and meet our contingent payment obligations and other long-term debt repayment obligations. Failure to generate sufficient revenues, raise additional capital through debt or equity financings, and/or reduce operating costs could have a material adverse effect on our ability to meet our short and long-term liquidity needs and achieve our intended long-term business objectives. Financial Condition Intangible Assets We consider our intellectual property, including patents, patent applications, trademarks, copyrights and trade secrets to be significant to our business. Our intangible assets are pledged as security for our secured contingent payment obligation with Brickell. The net book value of our intangible assets was approximately $1.8 million and $2.2 million as of December 31, 2021 and 2020, respectively. These assets are amortized using the straight-line method over their estimated period of benefit, generally fifteen to twenty years. The decrease in the carrying value of our intangible assets is primarily the result of $0.4 million in patent amortization expense recognized in 2021. Management evaluates the recoverability of intangible assets periodically and takes into account events or circumstances that may warrant revised estimates of useful lives or that may indicate impairment exists. As part of our ongoing patent maintenance program, we may, from time to time, abandon a particular patent if we determine fees to maintain the patent exceed its expected recoverability. For the years ended December 31, 2021 and 2020, we incurred losses of approximately $0.03 million and $0.3 million, respectively, for the write-off of specific patent assets. These losses are included in operating expenses in the accompanying consolidated statements of comprehensive loss. Contingent Payment Obligations We have secured and unsecured contingent payment obligations recorded at an aggregate estimated fair value of $43.1 million and $38.3 million as of December 31, 2021 and 2020, respectively. These repayment obligations are contingent upon receipt of proceeds from patent enforcement and other patent monetization actions. As a result, we have elected to account for these contingent payment obligations at their estimated fair values which are subject to significant estimates and assumptions as discussed in “Critical Accounting Policies” below. Refer to Note 10 to our consolidated financial statements included in Item 8 for a discussion of the fair value measurement of our contingent payment obligation. Our secured contingent payment obligation is payable to Brickell as a result of $18 million in borrowings under a 2016 funding agreement, as amended from time to time. We have repaid Brickell an aggregate of $3.3 million to date under this agreement. The contingent payment obligation to Brickell is recorded at its estimated fair market value of $37.4 million at December 31, 2021, an increase of $4.3 million or 13% from the estimated fair market value at December 31, 2020. Brickell is entitled to a priority, prorated payment of up to 100% of proceeds received by us from funded patent-related actions up to a specified minimum return. Brickell’s minimum return is determined as a multiple of the outstanding funded amount that increases over time. The estimated aggregate minimum return due to Brickell if repaid in full 17 at December 31, 2021 is approximately $48.8 million, an increase of approximately $6.8 million, or 16%, from the minimum return that would have been due to Brickell as of December 31, 2020. In addition, in 2020 and 2021, we incurred unsecured contingent payment obligations in connection with various funding arrangements. These contingent payment obligations are payable from our share of patent-related proceeds after satisfaction of our obligation to Brickell and payment of contingent fees to legal counsel. These unsecured contingent payment obligations are recorded at an aggregate estimated fair value of $5.7 million at December 31, 2021, representing an increase of $0.5 million from the estimated fair market value at December 31, 2020. This increase is primarily the result of $0.4 million in new unsecured contingent payment obligations incurred in 2021. The maximum payment obligation for our unsecured contingent payment obligations is $10.8 million at December 31, 2021. See “Change in Fair Value of Contingent Obligations” included in “Results of Operations” below for a discussion of the increase in the estimated fair value of our secured and unsecured contingent payment obligations. Note Payable As of December 31, 2021, we have a $0.7 million unsecured note payable to Sterne, Kessler, Goldstein, & Fox, PLLC (“SKGF”), a related party. We are obligated to make principal and interest payments totaling $0.12 million in 2022 under this note. The remaining outstanding balance of the note is subject to payment in full by April 30, 2023. Failure to comply with the payment terms of this note constitutes an event of default which, if uncured, will result in the entire unpaid principal balance of the note and any unpaid, accrued interest to become immediately due and payable. In addition, an event of default results in an increase in the interest rate under the notes to a default rate of 12% per annum. Notes payable are discussed more fully in Note 9 to our consolidated financial statements included in Item 8. Convertible Notes As of December 31, 2021, we have $2.9 million in notes that are convertible, at the holders’ option, into shares of our common stock at fixed conversion prices ranging from $0.08 to $0.57 per share. These notes mature at varying dates from September 2023 to January 2025. The majority of the notes bear interest at a stated rate of 8%, payable quarterly. We have the option, subject to certain conditions, to pay the quarterly interest in-kind with shares of our common stock based on market price at the interest payment date. To date, all of the interest payments under these convertible notes have been paid in-kind and we anticipate that future payments of interest will also be paid in-kind. The notes provide for events of default that include failure to pay principal or interest when due, breach of any of the representations made by us, events of liquidation or bankruptcy, and a change in control. In the event of default, the interest rate increases to 12% per annum and the outstanding principal balance of the notes plus all accrued interest due may be declared immediately payable by the holders of a majority of the then-outstanding notes. Our convertible notes payable are more fully discussed in Note 9 to our consolidated financial statements included in Item 8. Deferred Tax Assets and Related Valuation Allowance Deferred tax assets and liabilities are recognized for the expected future tax consequences of events that have been included in the financial statements or tax returns. Deferred tax assets and liabilities are determined based on differences between the financial statement carrying amounts and the tax bases of assets and liabilities using enacted tax rates in effect for the year in which the differences are expected to reverse. Valuation allowances are established to reduce deferred tax assets when, based on available objective evidence, it is more likely than not that the benefit of such assets will not be realized. As of December 31, 2021, we had net deferred tax assets of approximately $93 million, primarily related to our NOL carryforwards, which were fully offset by a valuation allowance due to the uncertainty related to realization of these assets through future taxable income. In addition, our ability to benefit from our NOL 18 and other tax credit carryforwards could be limited under Section 382 as more fully discussed in “Risk Factors” and in Note 11 to our consolidated financial statements included in Item 8. Results of Operations for Each of the Years Ended December 31, 2021 and 2020 Revenues and Gross Margins Licensing revenue was $0.14 million for the year ended December 31, 2021. We reported no licensing revenue for the year ended December 31, 2020. We entered into patent licensing and settlement agreements with Buffalo and Zyxel in May 2021 and September 2021, respectively. We recognized revenue from these contracts during the year ended December 31, 2021 when the parties’ performance obligations were met. Cost of sales related to the licensing revenue consists of amortization expense related to the patents covered under the license agreements. Our licensing proceeds were fully offset against out-of-pocket expenses recognized under our contingent fee agreement with counsel and therefore did not impact our cash flows. These out-of-pocket expenses are included in selling, general and administrative expenses. Although we do anticipate additional revenue to result from our licensing and patent enforcement actions, the amount and timing is highly unpredictable and there can be no assurance that we will achieve our anticipated results. We reported no product revenue during the years ended December 31, 2021 or 2020. Selling, General, and Administrative Expenses Selling, general and administrative expenses consist primarily of executive, director, technical support, and finance and administrative personnel costs, including share-based compensation, costs incurred for insurance, shareholder relations and outside legal and professional services, including litigation expenses, and amortization and maintenance expenses related to our patent assets. Our selling, general and administrative expenses were approximately $8.1 million for the year ended December 31, 2021, as compared to approximately $10.7 million for the year ended December 31, 2020, representing a decrease of approximately $2.6 million or 24%. This decrease results, in part, from a number of one-time, noncash charges in 2020 including $1.8 million associated with an amendment to a warrant agreement, $0.4 million from an amendment to our March 2020 equity transactions, and $0.2 million for impairment of the right-of- use asset associated with our Lake Mary lease. In addition, our litigation fees and expenses decreased by approximately $2.3 million as a result of the stay in the Qualcomm case in Jacksonville, Florida. These decreases were partially offset by a $2.1 million increase in share- based compensation attributed to nonqualified stock options awarded to executives, key employees, and nonemployee directors in January 2021 as more fully discussed in Note 14 to our consolidated financial statements included in Item 8. Change in Fair Value of Contingent Payment Obligations We have elected to measure our secured and unsecured contingent payment obligations at fair value which is based on significant unobservable inputs. We estimated the fair value of our secured contingent payment obligations using a probability-weighted income approach based on the estimated present value of projected future cash outflows using a risk-adjusted discount rate. Increases or decreases in the significant unobservable inputs could result in significant increases or decreases in fair value. 19 For the year ended December 31, 2021, we recorded an increase in the fair value of our secured and unsecured contingent payment obligations of approximately $4.4 million. The majority of the change in fair value is attributable to an increase in the estimated fair value of the secured contingent obligation with Brickell as a result of changes in estimated amounts and timing of projected future cash flows. Critical Accounting Policies We believe that the following are critical accounting policies and estimates that significantly impact the preparation of our consolidated financial statements: Contingent Payment Obligations We have accounted for our secured and unsecured contingent payment obligations as long-term debt. Our repayment obligations are contingent upon the receipt of proceeds from patent enforcement or other patent monetization actions. We have elected to measure our contingent payment obligations at their estimated fair values based on the variable and contingent nature of the repayment provisions. We have determined that the fair value of our secured and unsecured contingent payment obligations falls within Level 3 in the fair value hierarchy, which involves significant estimates and assumptions including projected future patent-related proceeds and the risk-adjusted rate for discounting future cash flows. Actual results could differ from the estimates made. Changes in fair value, including the component related to imputed interest, are included in the consolidated statements of comprehensive loss under the heading “Change in fair value of contingent payment obligations.” Refer to Note 10 to our consolidated financial statements included in Item 8 for a discussion of the significant estimates and assumptions used in estimated the fair value of our contingent payment obligations. Accounting for Share-Based Compensation We calculate the fair value of share-based equity awards to employees, including restricted stock, stock options and restricted stock units (“RSUs”), on the date of grant and recognize the calculated fair value as compensation expense over the requisite service periods of the related awards. The fair value of stock option awards is determined using the Black-Scholes option valuation model that requires the use of highly subjective assumptions and estimates including how long employees will retain their stock options before exercising them and the volatility of our common stock price over the expected life of the equity award. Changes in these subjective assumptions can materially affect the estimate of fair value of share-based compensation and consequently, the related amount recognized as expense in the consolidated statements of comprehensive loss. New Accounting Pronouncements We adopted Accounting Standards Update (“ASU”) 2020-06, "Debt - Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging - Contracts in Entity's Own Equity (Subtopic 815-40): Accounting for Convertible Instruments and Contracts in an Entity's Own Equity" as of January 1, 2021. ASU 2020-06 simplifies accounting for convertible instruments by removing major separation models required under current U.S. GAAP. Consequently, more convertible debt instruments will be reported as a single liability instrument with no separate accounting for embedded conversion features. The ASU removes certain settlement conditions that are required for equity contracts to qualify for the derivative scope exception, which will permit more equity contracts to qualify for the exception. The ASU also simplifies the diluted earnings per share calculation in certain areas. For smaller reporting companies, the ASU is effective for fiscal years beginning after December 15, 2023, including interim periods within those fiscal years, with early adoption permitted for fiscal years beginning after December 15, 2020. The ASU provides for a modified retrospective method of adoption whereby the guidance is applied to transactions outstanding at the beginning of the fiscal year of adoption with the cumulative effect of the change being recorded as an adjustment to beginning retained earnings. Adoption of ASU 2020-06 resulted in an increase to our long-term debt of approximately $0.8 million, a decrease in 20 additional paid-in-capital of approximately $1.1 million and an adjustment to our beginning accumulated deficit of $0.3 million resulting from the elimination of the previously recognized beneficial conversion feature as a debt discount. Off-Balance Sheet Transactions As of December 31, 2021, we had outstanding warrants to purchase 10.3 million shares of our common stock. The estimated grant date fair value of these warrants of approximately $3.2 million is included in shareholders’ deficit in our consolidated balance sheet for the year ended December 31, 2021. The outstanding warrants have an average exercise price of $0.75 per share and a weighted average remaining life of approximately 3 years. Item 7A. Quantitative and Qualitative Disclosures About Market Risk. Not applicable. 21 Item 8. Financial Statements and Supplementary Data. Index to Consolidated Financial Statements REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM (for the years ended December 31, 2021 and 2020) (PCAOB ID: 569) FINANCIAL STATEMENTS: Consolidated Balance Sheets – December 31, 2021 and 2020 Consolidated Statements of Comprehensive Loss - for the years ended December 31, 2021 and 2020 Consolidated Statements of Shareholders’ Deficit - for the years ended December 31, 2021 and 2020 Consolidated Statements of Cash Flows - for the years ended December 31, 2021 and 2020 Notes to Consolidated Financial Statements - December 31, 2021 and 2020 SUPPLEMENTARY DATA: Not applicable Page 22 24 25 26 27 28 22 REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM Board of Directors and Shareholders ParkerVision, Inc. Jacksonville, Florida Opinion on the Consolidated Financial Statements We have audited the accompanying consolidated balance sheets of ParkerVision, Inc. (the “Company”) and its subsidiary as of December 31, 2021 and 2020, and the related consolidated statements of comprehensive loss, shareholders’ deficit and cash flows for each of the years in the two-year period ended December 31, 2021, and the related notes (collectively referred to as the “consolidated financial statements”). In our opinion, the consolidated financial statements present fairly, in all material respects, the financial position of the Company and its subsidiary as of December 31, 2021 and 2020, and the results of their operations and their cash flows for each of the years in the two-year period ended December 31, 2021 in conformity with accounting principles generally accepted in the United States of America. Basis for Opinion These consolidated financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on the Company’s consolidated financial statements based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (PCAOB) and are required to be independent with respect to the Company in accordance with U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB. We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the consolidated financial statements are free of material misstatement, whether due to error or fraud. The Company is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. As a part of our audits, we are required to obtain an understanding of internal control over financial reporting, but not for the purpose of expressing an opinion on the effectiveness of the Company’s internal control over financial reporting. Accordingly, we express no such opinion. Our audits included performing procedures to assess the risks of material misstatement of the consolidated financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the consolidated financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the consolidated financial statements. We believe that our audits provide a reasonable basis for our opinion. 23 Emphasis of Matter Regarding Going Concern The accompanying consolidated financial statements have been prepared assuming that the Company will continue as a going concern. As discussed in Note 2 to the consolidated financial statements, the Company has suffered recurring losses from operations and has a net capital deficiency that raise substantial doubt about its ability to continue as a going concern. Management’s plans in regard to these matters are also described in Note 2. The consolidated financial statements do not include any adjustments that might result from the outcome of this uncertainty. Our opinion is not modified with respect to this matter. Critical Audit Matters The critical audit matters communicated below are matters arising from the current period audit of the financial statements that were communicated or required to be communicated to the audit committee and that: (1) relate to accounts or disclosures that are material to the financial statements and (2) involved our especially challenging, subjective, or complex judgments. The communication of critical audit matters does not alter in any way our opinion on the financial statements, taken as a whole, and we are not, by communicating the critical audit matters below, providing separate opinions on the critical audit matters or on the accounts or disclosures to which they relate. Estimation of Fair Value of Contingent Payment Obligations As disclosed in Note 1 of the Company’s consolidated financial statements, the Company accounts for their secured and unsecured contingent payment obligations as long-term debt. Their payment obligations are contingent upon the receipt of proceeds from patent enforcement and/or patent monetization actions. The Company has elected to measure their contingent payment obligations at their estimated fair values. The Company recorded the fair value of their contingent payment obligations at approximately $43,063,000 as of December 31, 2021. Auditing management’s estimate of the fair value of their contingent payment obligations involved subjective evaluation and high degree of auditor judgement due to significant assumptions involved in estimating the receipt of proceeds from patent enforcement and/or patent monetization actions. Addressing the matter involved performing procedures and evaluating audit evidence in connection with forming our overall opinion on the consolidated financial statements. We obtained an understanding and evaluated the design of internal controls that address the risks of material misstatement relating to recording the contingent payment obligations at fair value. We tested the accuracy and completeness of the underlying data used in calculating the fair value. We evaluated management’s ability to accurately estimate the assumptions used to develop the fair value of the contingent payment obligations. We also involved an independent legal firm to assist in evaluating the reasonableness of the assumptions of future litigation outcomes used by the Company in estimating the receipt of proceeds from patent enforcement and/or patent monetization actions. /s/ MSL, P.A.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS DECEMBER 31, 2021 AND 2020 1. SIGNIFICANT ACCOUNTING POLICIES ParkerVision, Inc. and its wholly-owned German subsidiary, ParkerVision GmbH (collectively “ParkerVision”, “we” or the “Company”) is in the business of innovating fundamental wireless hardware technologies and products. We have determined that our business currently operates under a single operating and reportable segment. We have designed and developed proprietary radio frequency (“RF”) technologies and integrated circuits based on those technologies, and we license our technologies to others for use in wireless communication products. We have expended significant financial and other resources to research and develop our RF technologies and to obtain patent protection for those technologies in the United States of America (“U.S.”) and certain foreign jurisdictions. We believe certain patents protecting our proprietary technologies have been broadly infringed by others, and therefore the primary focus of our business plan is the enforcement of our intellectual property rights through patent infringement litigation and licensing efforts. We currently have patent enforcement actions ongoing in various U.S. district courts against providers of mobile handsets, smart televisions and other WiFi products and, in certain cases, their chip suppliers for the infringement of a number of our RF patents. We have made significant investments in developing and protecting our technologies, the returns on which are dependent upon the generation of future revenues for realization. Basis of Presentation Our consolidated financial statements are prepared in accordance with generally accepted accounting principles in the U.S. (“GAAP”). The consolidated financial statements include the accounts of ParkerVision, Inc. and our wholly-owned German subsidiary, ParkerVision GmbH, after elimination of all intercompany transactions and accounts. Use of Estimates in the Preparation of Financial Statements The preparation of financial statements in conformity with GAAP requires us to make estimates and assumptions that affect the reported amounts of assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting periods. The more significant estimates made by us include projected future cash flows and risk-adjusted discount rates for estimating the fair value of our contingent payment obligations, the volatility and estimated lives of share-based awards used in the estimate of the fair market value of share-based compensation, the assessment of recoverability of long-lived assets, the amortization periods for intangible and long-lived assets, and the valuation allowance for deferred taxes. Actual results could differ from the estimates made. We periodically evaluate estimates used in the preparation of the financial statements for continued reasonableness. Appropriate adjustments, if any, to the estimates used are made prospectively based upon such periodic evaluation. Cash and Cash Equivalents We consider cash and cash equivalents to include cash on hand, interest-bearing deposits, overnight repurchase agreements and investments with original maturities of three months or less when purchased. 29 Property and Equipment Property and equipment are stated at cost, less accumulated depreciation. Depreciation is determined using the straight-line method over the following estimated useful lives: Manufacturing and office equipment Leasehold improvements Furniture and fixtures Computer equipment and software 5-7 years Shorter of useful life or remaining life of lease 7 years 3-5 years The cost and accumulated depreciation of assets sold or retired are removed from their respective accounts, and any resulting net gain or loss is recognized in the accompanying consolidated statements of comprehensive loss. The carrying value of long-lived assets is reviewed on a regular basis for the existence of facts, both internally and externally, that may suggest impairment. Recoverability of assets to be held and used is measured by comparing the carrying amount of an asset to the estimated undiscounted future cash flows expected to be generated by the asset. If the carrying amount of the assets exceeds its estimated undiscounted future net cash flows, an impairment charge is recognized in the amount by which the carrying amount of the asset exceeds the fair value of the assets. Intangible Assets We capitalize outside legal costs and agency filing fees incurred in connection with securing the rights to our intellectual property. Patents, copyrights and other intangible assets are amortized using the straight-line method over their estimated period of benefit. We estimate the economic lives of our patents and copyrights to be fifteen to twenty years. Management evaluates the recoverability of intangible assets periodically and takes into account events or circumstances that may warrant revised estimates of useful lives or that may indicate impairment exists. As part of our ongoing patent maintenance program, we will, from time to time, abandon a particular patent if we determine fees to maintain the patent exceed its expected recoverability. The cost and accumulated amortization of abandoned intangible assets are removed from their respective accounts, and any resulting net loss is recognized in selling, general and administrative expenses in the accompanying consolidated statements of comprehensive loss. Contingent Payment Obligations We have accounted for our secured and unsecured contingent payment obligations as long-term debt in accordance with Accounting Standards Codification (“ASC”) 470-10-25, “Sales of Future Revenues or Various other Measures of Income.” Our payment obligations are contingent upon the receipt of proceeds from patent enforcement and/or patent monetization actions. We have elected to measure our contingent payment obligations at their estimated fair values in accordance with ASC 825, “Financial Instruments” based on the variable and contingent nature of the repayment provisions. We have determined that the fair value of our secured and unsecured contingent payment obligations falls within Level 3 in the fair value hierarchy, which involves significant estimates, and assumptions including projected future patent-related proceeds and the risk-adjusted rate for discounting future cash flows (see Note 10). Actual results could differ from the estimates made. Changes in fair value, including the component related to imputed interest, are included in the accompanying consolidated statements of comprehensive loss under the heading “Change in fair value of contingent payment obligations.” Leases We have accounted for our finance and operating leases in accordance with ASC 842, “Leases” which requires the recognition of lease right- of-use (“ROU”) assets and lease liabilities on our consolidated balance sheets for finance and operating leases with initial lease terms of more than 12 months. At inception of a lease, we determine if an arrangement contains a lease and whether that lease meets the classification criteria of a finance or operating lease. Some of our lease arrangements contain lease components (e.g. minimum rent payments) and non- lease components (e.g. services). For certain 30 equipment leases, we account for lease and non-lease components separately based on a relative fair market value basis. For all other leases, we account for the lease and non-lease components (e.g. common area maintenance) on a combined basis. For operating leases with terms greater than 12 months, we record the ROU asset and lease obligation at the present value of lease payments over the term using the implicit interest rate, when readily available, or our incremental borrowing rate for collateralized debt based on information available at the lease commencement date. Certain of our leases include rental escalation clauses, renewal options and/or termination options that are factored into our determination of lease payments when it is reasonably certain that the option will be exercised. We do not recognize ROU assets and lease liabilities for leases with terms at inception of twelve months or less. Finance leases are included in property and equipment and other accrued expenses on the consolidated balance sheets. Finance leases are recorded as an asset and an obligation at an amount equal to the present value of the minimum lease payments during the lease term. Amortization expense and interest expense associated with finance leases are included in selling, general, and administrative expense and interest expense, respectively, on the consolidated statements of comprehensive loss. Refer to Note 8 for additional disclosures related to our leases. Convertible Debt We have issued debt that is convertible, at the holder’s option, into shares of our common stock at fixed conversion prices. Certain of the convertible notes were issued with conversion prices that were below market value of our common stock on the closing date resulting in a beneficial conversion feature which we recorded to equity with a corresponding discount to the debt that was amortized over the life of the notes as interest expense. Effective January 1, 2021, we adopted Accounting Standards Update (“ASU”) 2020-06 "Debt - Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging - Contracts in Entity's Own Equity (Subtopic 815-40): Accounting for Convertible Instruments and Contracts in an Entity's Own Equity." This ASU simplifies accounting for convertible instruments by removing major separation models required under current U.S. GAAP. Consequently, more convertible debt instruments will be reported as a single liability instrument with no separate accounting for embedded conversion features. The ASU removes certain settlement conditions that are required for equity contracts to qualify for the derivative scope exception, which will permit more equity contracts to qualify for the exception. The ASU also simplifies the diluted earnings per share calculation in certain areas. For smaller reporting companies, the ASU is effective for fiscal years beginning after December 15, 2023, including interim periods within those fiscal years, with early adoption permitted for fiscal years beginning after December 15, 2020. The ASU provides for a modified retrospective method of adoption whereby the guidance is applied to transactions outstanding at the beginning of the fiscal year of adoption with the cumulative effect of the change being recorded as an adjustment to beginning retained earnings. Adoption of ASU 2020-06 resulted in an increase to our long-term debt of approximately $0.8 million, a decrease in additional paid-in- capital of approximately $1.1 million, and an adjustment to our beginning accumulated deficit of $0.3 million resulting from the elimination of the previously recognized beneficial conversion feature as a debt discount. Revenue Recognition We account for revenue under ASC 606, “Revenue from Contracts with Customers” which implements a common revenue standard that clarifies the principles for recognizing revenue. This revenue recognition model provides a five-step analysis in determining when and how revenue is recognized. These steps 31 include (1) identifying the contract with the customer, (2) identifying the performance obligations, (3) determining the transaction price, (4) allocating the transaction price to the performance obligations, and (5) recognizing revenue as the entity satisfies the performance obligation(s). Our revenue is derived from patent licensing and settlement agreements. We have an active monitoring and enforcement program with respect to our intellectual property rights that includes seeking appropriate compensation from third parties that utilize or have utilized our intellectual property without a license. As a result, we may receive payments as part of a settlement or in the form of court-awarded damages for a patent infringement dispute. The timing and amount of revenue recognized from each licensee depend 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 may include multiple performance obligations. These agreements can include performance obligations related to the settlement of past patent infringement liabilities, royalties on future covered products sold by licensees, access to a portfolio of technology as it exists at a point in time, and/or promises to provide technology updates to the portfolio during the term of the license. Refer to Note 3 for additional disclosures related to our revenue. Cost of Sales Cost of sales includes amortization of intangible assets directly linked with revenue generating licensing activities. Amortization expense for intangible assets that are not directly related to revenue generating licensing activities are included in selling, general, and administrative expenses in our consolidated statements of comprehensive loss. Accounting for Share-Based Compensation We have various share-based compensation programs which provide for equity awards including stock options, restricted stock units (“RSUs”) and restricted stock awards (“RSAs”). We calculate the fair value of share-based equity awards on the date of grant and recognize the calculated fair value as compensation expense over the requisite service periods of the related awards. We estimate the fair value of stock option awards using the Black-Scholes option valuation model. This valuation model requires the use of highly subjective assumptions and estimates including how long employees will retain their stock options before exercising them and the volatility of our common stock price over the expected life of the equity award. Such estimates, and the basis for our conclusions regarding such estimates, are outlined in detail in Note 14. Estimates of fair value are not intended to predict actual future events or the value ultimately realized by persons who receive equity awards. We account for forfeitures of share-based awards as they occur. Income Taxes The provision for income taxes is based on loss before taxes as reported in the accompanying consolidated statements of comprehensive loss. Deferred tax assets and liabilities are recognized for the expected future tax consequences of events that have been included in the financial statements or tax returns. Deferred tax assets and liabilities are determined based on differences between the financial statement carrying amounts and the tax basis of assets and liabilities using enacted tax rates in effect for the year in which the differences are expected to reverse. Valuation allowances are established to reduce deferred tax assets when, based on available objective evidence, it is more likely than not that the benefit of such assets will not be realized. Our deferred tax assets exclude unrecognized tax benefits which do not meet a more- likely-than-not threshold for financial statement recognition for tax positions taken or expected to be taken in a tax return. 32 Loss per Common Share Basic loss per common share is determined based on the weighted-average number of common shares outstanding during each year. Diluted loss per common share is the same as basic loss per common share as all potential common shares are excluded from the calculation, as their effect is anti-dilutive. The number of shares underlying outstanding options, warrants, unvested RSUs, and convertible notes at December 31, 2021 and 2020 were as follows (in thousands): Options outstanding Warrants outstanding Unvested RSUs Shares underlying convertible notes 2021 2020 23,215 10,346 - 20,157 53,718 12,240 12,850 187 23,557 48,834 These potential shares were excluded from the computation of diluted loss per share as their effect would have been anti-dilutive. 2. LIQUIDITY AND GOING CONCERN The accompanying consolidated financial statements as of and for the year ended December 31, 2021 were prepared assuming we will continue as a going concern, which contemplates that we will continue in operation and will be able to realize our assets and settle our liabilities and commitments in the normal course of business for a period of at least one year from the issuance date of these consolidated financial statements. These consolidated financial statements do not include any adjustments to reflect the possible future effects on the recoverability and classification of assets or the amounts and classification of liabilities that could result should we be unable to continue as a going concern. We have incurred significant losses from operations and negative cash flows in every year since inception and have utilized the proceeds from the sales of our equity and equity-linked securities and our contingent funding arrangements with third-parties to fund our operations, including our litigation costs. For the year ended December 31, 2021, we incurred a net loss of approximately $12.3 million and negative cash flows from operations of approximately $7.7 million. At December 31, 2021, we had an accumulated deficit of approximately $433.4 million. These circumstances raise substantial doubt about our ability to continue to operate as a going concern for a period of one year after the issuance date of these consolidated financial statements. We had cash and cash equivalents of approximately $1.0 million at December 31, 2021. Our remaining capital resources will be used to fund our current obligations and ongoing operating costs; however these resources will not be sufficient to meet our liquidity needs for the next twelve months and we will be required to seek additional capital. Our business plan is currently focused solely on our patent enforcement and technology licensing objectives. The timing and amount of proceeds from our patent enforcement actions are difficult to predict and there can be no assurance we will receive any proceeds from these enforcement actions. Refer to Note 12 for a complete discussion of our patent enforcement proceedings. Our ability to meet our liquidity needs for the twelve months after the issuance date of these financial statements is dependent upon one or more of (i) our ability to successfully negotiate licensing agreements and/or settlements relating to the use of our technologies by others in excess of our contingent payment 33 obligations and (ii) our ability to raise additional capital from the sale of debt or equity securities or other financing arrangements. We anticipate that we will continue to invest in patent protection, licensing, and enforcement of our wireless technologies. We expect that revenue generated from patent enforcement actions, and technology licenses over the twelve months after the issuance date of these financial statements, if any, after deduction of payment obligations to our third-party litigation funder and legal counsel, may not be sufficient to cover our operating expenses. In the event we do not generate revenues, or other patent-asset proceeds, sufficient to cover our operational costs and contingent repayment obligation, we will be required to raise additional working capital through the sale of equity securities or other financing arrangements. The long-term continuation of our business plan is dependent upon our ability to secure sufficient financing to support our business, and our ability to generate revenues and/or patent-related proceeds sufficient to offset expenses and meet our contingent payment obligation and other long-term debt repayment obligations. Failure to generate sufficient revenues, raise additional capital through debt or equity financings, and/or reduce operating costs could have a material adverse effect on our ability to meet our short and long-term liquidity needs and achieve our intended long-term business objectives. 3. REVENUE During the year ended December 31, 2021, we recognized $0.14 million of revenue derived from contracts with two licensees. The contracts provide access to specified patented technologies as they exist at a point in time and we have no obligation to provide any future updates. The consideration received by us was negotiated as part of a settlement of patent litigation where no prior license agreement existed. The performance obligations were satisfied upon our dismissal of patent enforcement actions with each licensee which was contingent upon our receipt of the negotiated and agreed-upon lump-sum payments from the licensees. The contracts included no variable consideration. All consideration received was recorded to licensing revenue as there were no other material components of the contracts. No contract assets or liabilities exist as of December 31, 2021. We recognized no revenue during the year ended December 31, 2020. 4. PREPAID EXPENSES Prepaid expenses consisted of the following at December 31, 2021 and 2020 (in thousands): Prepaid services Prepaid bonds for German statutory costs Prepaid insurance Prepaid licenses, software tools and support Other prepaid expenses $ $ 2021 2020 523 $ - 23 16 12 574 $ 408 142 21 11 17 599 Prepaid services at December 31, 2021 and 2020 include approximately $0.5 million and $0.1 million, respectively, of consulting services paid in shares of stock or warrants to purchase shares of stock in the future. 34 5. PROPERTY AND EQUIPMENT, NET Property and equipment, at cost, consisted of the following at December 31, 2021 and 2020 (in thousands): Equipment and software Leasehold improvements Furniture and fixtures Less accumulated depreciation $ $ 2021 2020 221 $ 19 - 240 (233) 7 $ 218 19 30 267 (237) 30 Depreciation expense related to property and equipment was approximately $0.01 million and $0.03 million in 2021 and 2020, respectively. For the years ended December 31, 2021 and 2020, we recorded a loss on disposal of fixed assets of approximately $0.01 million and $0.02 million, respectively. 6. INTANGIBLE ASSETS Intangible assets consisted of the following at December 31, 2021 and 2020 (in thousands): Patents and copyrights Less accumulated amortization 2021 2020 $ $ 14,755 $ (12,970) 1,785 $ 14,948 (12,778) 2,170 Amortization expense for the years ended December 31, 2021 and 2020 was approximately $0.35 million and $0.45 million, respectively. For the years ended December 31, 2021 and 2020, we recorded losses on the disposal of intangible assets of approximately $0.03 million and $0.3 million, respectively. Future estimated amortization expense for intangible assets that have remaining unamortized amounts as of December 31, 2021 is as follows (in thousands): 2022 2023 2024 2025 2026 2027 and thereafter Total $ $ 309 278 265 226 155 552 1,785 35 7. ACCRUED LIABILITIES Other accrued expenses consisted of the following at December 31, 2021 and 2020 (in thousands): Advances Other accrued expenses $ $ 2021 2020 500 $ 55 555 $ 882 54 936 Advances include amounts received from litigation counsel as advanced reimbursement of out-of-pocket expenses expected to be incurred by us and, at December 31, 2020, includes approximately $0.4 million received from investors for the purchase of equity securities in a January 2021 transaction (see Note 13). 8. LEASES We lease our office and other facilities and certain office equipment under long-term, non-cancelable operating leases. No new finance or operating leases commenced during the years ended December 31, 2021 or 2020 except with respect to a sublease agreement for our Lake Mary facility in 2021 as discussed more fully below. During the year ended December 31, 2020, we recognized an impairment loss of approximately $0.2 million on the ROU asset related to our Lake Mary office lease. We ceased use of this facility in 2018 as part of a restructuring of our operations. The original value of our ROU asset included estimated future sublease income. Due to a number of factors, including the high vacancy rate of the building in which the space is located and the pandemic, we determined securing a sublease for the space would be unlikely. The impairment loss recognized in 2020 represented the remaining carrying value of the asset and is included in selling, general, and administrative expenses in our consolidated statements of comprehensive loss. During the year ended December 31, 2021, we entered into a sublease agreement for this facility for the remaining term of our original lease, through November 2022. The sublease is accounted for as an operating lease. Lease expense for operating leases is generally recognized on a straight-line basis over the lease term and is included in operating expenses on the consolidated statement of comprehensive loss. We recognized operating lease costs of $0.04 million and $0.1 million for the years ended December 31, 2021 and 2020, respectively. Rental income recognized of $0.05 million for the year ended December 31, 2021, is included in “Interest and other income” in the accompanying consolidated statements of comprehensive loss. 36 Supplemental Cash Flow Information The following table summarizes the supplemental cash flow information related to leases (in thousands): Cash paid for amounts included in the measurement of lease liabilities: Operating cash flows from operating leases Cash received for amounts included in the measurement of sublease assets: Operating cash flows from operating subleases Other Information The table below summarizes other supplemental information related to leases: Weighted-average remaining lease term (in years): Operating leases Operating subleases Weighted average discount rate Operating leases (1) Year Ended December 31, 2021 Year Ended December 31, 2020 $ 181 $ 44 315 - December 31, 2021 December 31, 2020 0.9 0.9 12.2% 1.7 - 12.1% (1) Upon adoption of the new lease standard, discount rates used for existing leases were established at January 1, 2019.

LONG-TERM DEBT Notes Payable Note Payable to a Related Party We have an unsecured promissory note payable of $0.7 million to Sterne, Kessler, Goldstein, & Fox, PLLC (“SKGF”), a related party (see Note 15), for outstanding unpaid fees for legal services. The note, as amended, accrues interest at 4% per annum and provides for monthly payments of principal and interest of $10,000 with a final balloon payment of approximately $0.59 million due at the maturity date of April 30, 2023. We are currently in compliance with all the terms of the note, as amended. For each of the years ended December 31, 2021 and 2020, we recognized interest expense of approximately $0.03 million related to this note. Unsecured Notes Payable Unsecured notes payable at December 31, 2020 represents the current portion of our Paycheck Protection Program loan. In May 2020, we received approximately $0.2 million in proceeds from an approved loan under the Paycheck Protection Program. The loan was eligible for forgiveness provided that (i) we used the loan proceeds exclusively for allowed costs including payroll, employee group health benefits, rent and utilities and (ii) employee and compensation levels were maintained during the coverage period. We applied for loan forgiveness in April 2021 and the loan was forgiven in June 2021. The forgiveness of the loan was recognized as income and is included in “Interest and other income” in the accompanying consolidated statements of comprehensive loss for the year ended December 31, 2021. Secured Note Payable Our secured note payable as of December 31, 2020 represented default interest accrued related to a note payable to Mintz, Levin, Cohn, Ferris, Glovsky and Popeo, P.C. (“Mintz”) for outstanding fees and expenses. Additionally, as of December 31, 2020, we had approximately $3.1 million in accounts payable to Mintz for outstanding fees and expenses. We also had approximately $3.6 million in disputed legal fees and expenses billed by Mintz that we treated as a loss contingency that was not probable as of December 31, 2020 and accordingly, for which we recognized no expense in the consolidated financial statements. On March 29, 2021, we entered into an agreement with Mintz to satisfy our outstanding obligations to Mintz. Under the terms of the agreement, (i) Mintz waived all past defaults on the note resulting in a reversal of previously accrued interest, (ii) we paid Mintz a lump-sum payment of $3.0 million in satisfaction of all outstanding obligations including our accounts payable to Mintz and all disputed and unrecorded billings, and (iii) Mintz agreed to a significant reduction in future success fees that might be payable to Mintz from future patent-related proceeds. At December 31, 2021, the aggregate maturities of our notes payable are as follows (in thousands): 2022 2023 Total $ $ 94 609 703 The estimated fair value of our notes payable at December 31, 2021 is approximately $0.63 million based on a risk-adjusted discount rate. 38 Convertible Notes Our convertible notes represent five-year promissory notes that are convertible, at the holders’ option, into shares of our common stock at fixed conversion prices. Interest payments are made on a quarterly basis and are payable, at our option and subject to certain equity conditions, in either cash, shares of our common stock, or a combination thereof. The number of shares issued for interest is determined by dividing the interest payment amount by the closing price of our common stock on the trading day immediately prior to the scheduled interest payment date. To date, all interest payments on the convertible notes have been made in shares of our common stock. We have recognized the convertible notes as debt in our consolidated financial statements. The fixed conversion prices of certain of the notes were below the market value of our common stock on the closing date resulting in the recognition of a beneficial conversion feature that was recorded as a discount on the convertible notes with a corresponding increase to additional paid in capital. Upon our adoption of ASU 2020-06 on January 1, 2021, the previously recognized beneficial conversion feature was eliminated resulting in an increase in convertible notes of $0.8 million (see Note 1). Convertible notes payable at December 31, 2021 and 2020, consist of the following (in thousands): Description Convertible notes dated September 10, 2018 Convertible notes dated September 19, 2018 Convertible notes dated February/March 2019 Convertible notes dated June/July 2019 Convertible notes dated July 18, 2019 Convertible notes dated September 13, 2019 Convertible notes dated January 8, 2020 Total principal balance Less unamortized discount Fixed Conversion Rate $0.40 $0.57 $0.25 $0.10 $0.08 $0.10 $0.13 Interest Rate 8.0% 8.0% 8.0% 8.0% 7.5% 8.0% 8.0% Maturity Date September 10, 2023 $ September 19, 2023 February 28, 2024 to March 13, 2024 June 7, 2024 to July 15, 2024 July 18, 2024 September 13, 2024 January 8, 2025 1 $ December 31, 2021 2020 200 425 750 320 700 50 450 2,895 - 2,895 $ $ 600 425 1,300 340 700 50 450 3,865 847 3,018 1 The maturity date may be extended by one-year increments for up to an additional five years at the holder’s option at a reduced interest rate of 2%. We have the option to prepay the majority of the notes any time following the one-year anniversary of the issuance of the notes, subject to a premium on the outstanding principal prepayment amount of 25% prior to the two-year anniversary of the note issuance date, 20% prior to the three-year anniversary of the note issuance date, 15% prior to the four-year anniversary of the note issuance date, or 10% thereafter. The notes provide for events of default that include failure to pay principal or interest when due, breach of any of the representations, warranties, covenants or agreements made by us, events of liquidation or bankruptcy, and a change in control. In the event of default, the interest rate increases to 12% per annum and the outstanding principal balance of the notes plus all accrued interest due may be declared immediately payable by the holders of a majority of the then outstanding principal balance of the notes. 39 For the year ended December 31, 2021, convertible notes with a face value of $0.97 million were converted by the holders into 3.4 million shares of our common stock at an average conversion price of $0.29. For the year ended December 31, 2020, convertible notes with a face value of $0.15 million were converted by the holders into 0.75 million shares of our common stock at an average conversion price of $0.20. At the holders’ option, subject to ownership limitations, the convertible notes outstanding at December 31, 2021 could be converted into an aggregate of approximately 20.2 million shares of our common stock based on the fixed conversion prices. For the years ended December 31, 2021 and 2020, we recognized interest expense of approximately $0.26 million and $0.47 million, respectively. Interest expense for the year ended December 31, 2020 included approximately $0.17 million related to amortization of the discount that was subsequently eliminated upon our adoption of ASU 2020-06. We have elected to pay contractual interest in shares of our common stock. For the years ended December 31, 2021 and 2020, we issued approximately 272,000 and 710,000 shares of our common stock, respectively, as interest-in-kind payments on our convertible notes. All of the shares underlying our convertible notes, including shares reserved for future in-kind interest payments on the notes, have been registered for resale. At December 31, 2021, we estimate our convertible notes have an aggregate fair value of approximately $2.3 million and would be categorized within Level 2 of the fair value hierarchy. Secured Contingent Payment Obligation The following table provides a reconciliation of our secured contingent payment obligation measured at estimated fair market value for the years ended December 31, 2021 and 2020, respectively (in thousands). Secured contingent payment obligation, beginning of year Change in fair value Secured contingent payment obligation, end of year 2021 2020 $ $ 33,057 $ 4,315 37,372 $ 26,651 6,406 33,057 Our secured contingent payment obligation represents the estimated fair value of our repayment obligation to Brickell Key Investments, LP (“Brickell”) under a February 2016 funding agreement, as amended from time to time (the “CPIA”). To date, we have received aggregate proceeds of $18 million in exchange for Brickell’s right to reimbursement and compensation from gross proceeds resulting from patent enforcement and other patent monetization actions. No proceeds were received from Brickell in 2020 or 2021. To date, we have repaid an aggregate of $3.3 million under the CPIA from patent license and settlement proceeds. Brickell is entitled to priority payment of 100% of proceeds received by us, after reimbursement of out-of-pocket expenses and legal contingent fees, from all patent-related actions until such time that Brickell has been paid its minimum return. The minimum return is determined as a multiple of the funded amount that increases over time. The estimated minimum return due to Brickell was approximately $48.8 million and $42 million as of December 31, 2021 and 2020, respectively. In addition, Brickell is entitled to a pro rata portion of proceeds from specified legal actions to the extent aggregate proceeds from those actions exceed the minimum return. Brickell holds a senior security interest in the majority of our assets until such time as the specified minimum return is paid, in which case, the security interest will be released except with respect to the 40 patents and proceeds related to specific legal actions. The security interest is enforceable by Brickell in the event that we are in default under the agreement which would occur if (i) we fail, after notice, to pay proceeds to Brickell, (ii) we become insolvent or insolvency proceedings are commenced (and not subsequently discharged) with respect to us, (iii) our creditors commence actions against us (which are not subsequently discharged) that affect our material assets, (iv) we, without Brickell’s consent, incur indebtedness other than immaterial ordinary course indebtedness, or (v) there is an uncured non-compliance of our obligations or misrepresentations under the agreement. As of December 31, 2021, we are in compliance with our obligations under this agreement. In addition, in the event of a change in control of the Company, Brickell has the right to be paid its return as defined under the CPIA based on the transaction price for the change in control event. We have elected to measure our secured contingent payment obligation at its estimated fair value based on probability-weighted estimated cash outflows, discounted back to present value using a discount rate determined in accordance with accepted valuation methods (see Note 10). The secured contingent payment obligation is remeasured to fair value at each reporting period with changes recorded in the consolidated statements of comprehensive loss until the contingency is resolved. Unsecured Contingent Payment Obligations The following table provides a reconciliation of our unsecured contingent payment obligations, measured at estimated fair market value, for the years ended December 31, 2021 and 2020, respectively (in thousands): Unsecured contingent payment obligations, beginning of period Reclassification of other liabilities Issuance of contingent payment rights Change in fair value Unsecured contingent payment obligations, end of period 2021 2020 $ $ 5,222 $ - 412 57 5,691 $ - 1,003 2,258 1,961 5,222 Our unsecured contingent payment obligations represent amounts payable to others from future patent-related proceeds including (i) a termination fee due to a litigation funder (“Termination Fee”) and (ii) contingent payment rights (“CPRs”) issued to accredited investors primarily in connection with equity financings. We have elected to measure these unsecured contingent payment obligations at their estimated fair value based on probability-weighted estimated cash outflows, discounted back to present value using a discount rate determined in accordance with accepted valuation methods. The unsecured contingent payment obligations will be remeasured to fair value at each reporting period with changes recorded in the consolidated statements of comprehensive loss until the contingency is resolved (see Note 10). The Termination Fee is a result of advances received under a letter agreement with a third-party funder of $0.4 million in 2019 and $0.6 million in 2020. Based on the terms of the letter agreement, if a final funding arrangement was not executed by March 31, 2020, we would be obligated to pay, from future patent-related proceeds, an aggregate termination payment equal to five times the advances received, or approximately $5.0 million. We did not consummate a funding agreement and accordingly the advances were recorded as an unsecured contingent payment obligation at March 31, 2020, when the Termination Fee obligation was incurred. As of December 31, 2021, the estimated fair value of unsecured contingent payment obligations related to the Termination Fee is $2.6 million. 41 The CPRs represent the estimated fair value of rights provided to accredited investors who purchased shares of our common stock in 2020 and 2021 and the fair value of a right issued to a third-party in connection with a service agreement during the year ended December 31, 2020 (see Note 13). During the years ended December 31, 2021 and 2020, we received aggregate proceeds of $1.1 million and $3.8 million, respectively from the sale of common stock with contingent payment rights, of which approximately $0.4 million and $1.8 million, respectively was allocated to the CPRs. In addition, on May 1, 2020, we amended certain March 2020 equity purchase agreements with accredited investors for the purchase of $0.9 million in common stock to add CPRs. This amendment resulted in a charge to expense of $0.4 million for the initial estimated fair value of the CPRs. The terms of the CPRs provide that we will pay each investor an allocated portion of our net proceeds from patent-related actions, after taking into account fees and expenses payable to law firms representing us and amounts payable to Brickell. The investors’ allocated portion of net proceeds will be determined by multiplying the net proceeds recovered by us (up to $10 million) by the quotient of such investors’ subscription amount divided by $10 million, up to an amount equal to each investor’s subscription amount, or an aggregate of $5.8 million. As of December 31, 2021, the estimated fair value of our unsecured contingent payment obligations related to the CPRs is $3.1 million. 10. FAIR VALUE MEASUREMENTS ASC 820, “Fair Value Measurements” establishes a fair value hierarchy that prioritizes the inputs to valuation methods used to measure fair value. The three levels of the fair value hierarchy are as follows: (cid:0) Level 1: Quoted prices for identical assets or liabilities in active markets which we can access (cid:0) Level 2: Observable inputs other than those described in Level 1 (cid:0) Level 3: Unobservable inputs The following table summarizes financial assets and financial liabilities carried at fair value and measured on a recurring basis as of December 31, 2021 and 2020, segregated by classification within the fair value hierarchy (in thousands): Quoted Prices in Active Markets (Level 1) Fair Value Measurements Significant Other Observable Inputs (Level 2) Significant Unobservable Inputs (Level 3) Total December 31, 2021: Liabilities: Secured contingent payment obligation Unsecured contingent payment obligations $ 37,372 $ 5,691 December 31, 2020: Liabilities: Secured contingent payment obligation Unsecured contingent payment obligations 33,057 5,222 - $ - - - - $ - 37,372 5,691 - - 33,057 5,222 For the years ended December 31, 2021 and 2020, respectively, we had no transfers of assets or liabilities between the levels of the hierarchy. 42 The fair values of our secured and unsecured contingent payment obligations were estimated using a probability-weighted income approach based on various cash flow scenarios as to the outcome of patent-related actions both in terms of timing and amount, discounted to present value using a risk-adjusted rate. We used a risk-adjusted discount rate of 14.85% at December 31, 2021, based on a risk-free rate of 0.85% as adjusted by 8% for credit risk and 6% for litigation inherent risk. The following table provides quantitative information about the significant unobservable inputs used in the measurement of fair value for both the secured and unsecured contingent payment obligations at December 31, 2021, including the lowest and highest undiscounted payout scenarios as well as a weighted average payout scenario based on relative undiscounted fair value of each cash flow scenario. Unobservable Inputs Secured Contingent Payment Obligation Weighted Average High Low Unsecured Contingent Payment Obligations Weighted Average High Low Estimated undiscounted cash outflows (in millions) Duration (in years) Estimated probabilities $ $ 0.0 0.5 7% $ 51.8 2.3 23% $ 79.6 3.5 25% $ 0.0 1.5 25% $ 8.1 2.5 25% 10.8 3.5 25% We evaluate the estimates and assumptions used in determining the fair value of our contingent payment obligations each reporting period and make any adjustments prospectively based on those evaluations. Changes in any of these Level 3 inputs could result in a significantly higher or lower fair value measurement 11. INCOME TAXES AND TAX STATUS Our net losses before income taxes for the years ended December 31, 2021 and 2020 are from domestic operations as well as losses from our wholly-owned German subsidiary. We elected to treat our German subsidiary as a disregarded entity for purposes of income taxes and accordingly, the losses from our German subsidiary have been included in our operating results. No current or deferred tax provision or benefit was recorded in 2021 or 2020 as a result of current losses and fully deferred tax valuation allowances for all periods. We have recorded a valuation allowance to state our deferred tax assets at their estimated net realizable value due to the uncertainty related to realization of these assets through future taxable income. A reconciliation between the provision for income taxes and the expected tax benefit using the federal statutory rate of 21% for each of the years ended December 31, 2021 and 2020, respectively are as follows (in thousands): Tax benefit at statutory rate State tax benefit Increase in valuation allowance Other 2021 2020 $ $ (2,589) $ (530) 3,368 (249) - $ (4,111) (842) 4,307 646 - 43 Our deferred tax assets and liabilities relate to the following sources and differences between financial accounting and the tax bases of our assets and liabilities at December 31, 2021 and 2020 (in thousands): Gross deferred tax assets: Net operating loss carry-forward Research and development credit carry-forward Stock compensation Patents and other Contingent payment obligations Fixed assets Accrued liabilities Lease liabilities Less valuation allowance Gross deferred tax liabilities: Convertible debt Net deferred tax asset 2021 2020 78,600 $ 6,028 356 1,470 6,341 53 - 38 92,886 (92,886) - - - - $ 80,848 6,603 122 1,466 5,235 54 64 77 94,469 (94,245) 224 (224) (224) - $ $ Upon adoption of ASU 2020-06 on January 1, 2021 (see “Convertible Notes” in Note 9), the difference between the financial accounting and tax bases, net of tax effect, of unrecognized tax benefit related to the beneficial conversion feature of convertible debt was eliminated. At December 31, 2021, we had cumulative net operating loss (“NOL”) carry-forwards for income tax purposes of $313.2 million, of which $276.6 million is subject to expiration in varying amounts from 2022 to 2037. At December 31, 2021, we also had research and development tax credit carryforwards of $6.0 million, which expire in varying amounts from 2022 through 2038. Our ability to benefit from the tax credit carry-forwards could be limited under certain provisions of the Internal Revenue Code if there are ownership changes of more than 50%, as defined by Section 382 of the Internal Revenue Code of 1986 (“Section 382”). Under Section 382, an ownership change may limit the amount of NOL, capital loss and R&D credit carry-forwards that can be used annually to offset future taxable income and tax, respectively. In general, an ownership change, as defined by Section 382, results from transactions increasing the ownership of certain shareholders or public groups in the stock of a corporation by more than 50 percentage points over a three-year period. We conduct a study annually of our ownership changes. Based on the results of our studies, we have determined that we do not have any ownership changes on or prior to December 31, 2021 which would result in limitations of our NOL, capital loss or R&D credit carry- forwards under Section 382. Uncertain Tax Positions We file income tax returns in the U.S. federal jurisdiction, various state jurisdictions, and Germany. We have identified our Federal and Florida tax returns as our only major jurisdictions, as defined. The periods subject to examination for those returns are the 2002 through 2021 tax years. The following table 44 provides a reconciliation of our unrecognized tax benefits due to uncertain tax positions for the years ended December 31, 2021 and 2020, respectively (in thousands): Unrecognized tax benefits – beginning of year Reduction as a result of lapse of statute of limitations Unrecognized tax benefits – end of year 2021 2020 $ $ 927 $ (274) 653 $ 927 - 927 Future changes in the unrecognized tax benefit will have no impact on the effective tax rate so long as we maintain a full valuation allowance. Our policy is that we recognize interest and penalties accrued on any unrecognized tax benefits as a component of our income tax expense. We do not have any accrued interest or penalties associated with any unrecognized tax benefits. For the years ended December 31, 2021 and 2020, we did not incur any income tax-related interest income, expense or penalties. 12. COMMITMENTS AND CONTINGENCIES Legal Proceedings From time to time, we are subject to legal proceedings and claims which arise in the ordinary course of our business. These proceedings include patent enforcement actions initiated by us against others for the infringement of our technologies, as well as proceedings brought by others against us at the Patent Trial and Appeal Board of the U.S. Patent and Trademark Office (“PTAB”) and in the Federal Patent Court in Germany in an attempt to invalidate certain of our patent claims. The majority of our litigation, including our PTAB proceedings, is being paid for through contingency fee arrangements with our litigation counsel as well as third-party litigation financing. In general, litigation counsel is entitled to recoup on a priority basis, from litigation proceeds, any out-of-pocket expenses incurred. Following reimbursement of out-of-pocket expenses, litigation counsel is generally entitled to a percentage of remaining proceeds based on the terms of the specific arrangement between us, counsel and our third-party litigation funder. We were liable for costs assessed on infringement and validity cases in Germany in which we did not prevail. A portion of this liability was covered by bonds posted in Germany. As of December 31, 2021, our bonds have been fully released and all outstanding statutory court costs have been satisfied in full. We have no remaining litigation or related liabilities in Germany. ParkerVision v. Qualcomm (Middle District of Florida) We have a patent infringement complaint pending in the Middle District of Florida against Qualcomm and Qualcomm Atheros, Inc. (collectively “Qualcomm”) seeking approximately $1.3 billion in damages for infringement of four of our patents (the “Qualcomm Action”). HTC Corporation and HTC America, Inc. (collectively “HTC”) were also defendants in this case but we voluntarily dismissed our claims against HTC and HTC dismissed their related counter-claims against us in October 2020. Qualcomm has pending counterclaims against us for non-infringement and invalidity for all patents in the case. The case was filed in May 2014 and stayed in February 2016 pending decisions in other cases, including the appeal of a PTAB proceeding with regard to U.S. patent 6,091,940 (“the ‘940 Patent”) asserted in this case. In March 2017, the PTAB ruled in our favor on three of the six petitions (the method claims), ruled in Qualcomm’s favor on two of the six petitions (the apparatus claims) and issued a split decision on the claims covered in the sixth petition. In September 2018, the Federal 45 Circuit upheld the PTAB’s decision with regard to the ‘940 Patent and, in January 2019, the court lifted the stay in this case. In July 2019, the court issued an order that granted our proposed selection of patent claims from four asserted patents, including the ‘940 Patent, and denied Qualcomm’s request to limit the claims and patents. The court also agreed that we may elect to pursue accused products that were at issue at the time the case was stayed, as well as new products that were released by Qualcomm during the pendency of the stay. In September 2019, Qualcomm filed a motion for partial summary judgement in an attempt to exclude certain patents from the case, including the ‘940 Patent. The court denied this motion in January 2020. In April 2020, the court issued its claim construction order in which the court adopted our proposed construction for seven of the ten disputed terms and adopted slightly modified versions of our proposed construction for the remaining terms. Due to the impact of COVID-19, a number of the scheduled deadlines in this case were moved including the trial commencement date which was rescheduled from December 2020 to May 2021. In October 2020, our damages expert submitted a report supporting our damages ask of $1.3 billion for Qualcomm’s unauthorized use of our technology. Such amount excludes additional amounts requested by us for interest and enhanced damages for willful infringement. Ultimately, the amount of damages, if any, will be determined by the court. Discovery was expected to close in December 2020; however, the court allowed us to designate a substitute expert due to medical issues with one of our experts in the case. Accordingly, the close of discovery was delayed until January 2021. As a result of these delays, the court rescheduled the trial commencement date from May 3, 2021 to July 6, 2021. In March 2021, the court further delayed the trial date citing backlog due to the pandemic, among other factors. A new trial date has not yet been set. Fact and expert discovery in this case are closed, expert reports have been submitted, and summary judgement and Daubert briefings have been completed by the parties. Joint pre-trial statements were submitted in May 2021. In March 2021, the court granted Qualcomm’s motion to strike certain of our 2020 infringement contentions. We filed a motion to clarify the court’s order and in July 2021, based on the court’s response to our motion to clarify, we filed a joint motion for entry of a judgement of non-infringement of our Patent No. 7,865,177 (“the ‘177 Patent”), subject to appeal. A number of outstanding motions are pending decisions by the court. In January 2022, the court held a hearing to allow the parties to present their respective positions on three outstanding motions. The court indicated that upon its ruling on these motions, a pre-trial conference will be scheduled and a trial date set. On March 9, 2022, the court ruled with respect to one of these motions granting Qualcomm’s motion to strike and exclude opinions regarding the alleged infringement and validity issues. This court order prevents the presentation of infringement and validity opinions by both of our experts at trial. In addition, on March 22, 2022, the court issued an order granting Qualcomm’s motion for summary judgment ruling that Qualcomm does not infringe the remaining three patents in this case. This is a final judgment and the next step is an appeal of both the March 22, 2022 and the March 9, 2022 rulings (see Note 17). We are represented in this case on a full contingency fee basis. ParkerVision v. Apple and Qualcomm (Middle District of Florida) In December 2015, we filed a patent infringement complaint in the Middle District of Florida against Apple, LG, Samsung and Qualcomm alleging infringement of four of our patents. In February 2016, the district court proceedings were stayed pending resolution of a corresponding case filed at the International Trade Commission (“ITC”). In July 2016, we entered into a patent license and settlement agreement with Samsung and, as a result, Samsung was dismissed from the district court action. In March 2017, we filed a motion to terminate the ITC proceedings and a corresponding motion to lift the stay in the district court case. This motion was granted in May 2017. In July 2017, we filed a motion to dismiss LG from the district court case and re-filed our claims against LG in the District of New Jersey (see ParkerVision v. LG below). Also in July 2017, Qualcomm filed a motion to change venue to the Southern District of California, and Apple filed a motion to dismiss for improper venue. In March 2018, the district court 46 ruled against the Qualcomm and Apple motions. The parties also filed a joint motion in March 2018 to eliminate three of the four patents in the case in order to expedite proceedings leaving our U.S. patent 9,118,528 as the only remaining patent in this case. A claim construction hearing was held on August 31, 2018. In July 2019, the court issued its claim construction order in which the court adopted our proposed claim construction for two of the six disputed terms and the “plain and ordinary meaning” on the remaining terms. In addition, the court denied a motion filed by Apple for summary judgment. Fact discovery has closed in this case and a jury trial was scheduled to begin in August 2020. In March 2020, as a result of the impact of COVID-19, the parties filed a motion requesting an extension of certain deadlines in the case. In April 2020, the court stayed this proceeding pending the outcome of the Qualcomm Action. ParkerVision v. LG (District of New Jersey) In July 2017, we filed a patent infringement complaint in the District of New Jersey against LG for the alleged infringement of the same patents previously asserted against LG in the Middle District of Florida (see ParkerVision v. Apple and Qualcomm above). We elected to dismiss the case in the Middle District of Florida and re-file in New Jersey as a result of a Supreme Court ruling regarding proper venue. In March 2018, the court stayed this case pending a final decision in ParkerVision v. Apple and Qualcomm in the Middle District of Florida. As part of this stay, LG has agreed to be bound by the final claim construction decision in that case. ParkerVision v. Intel (Western District of Texas) In February 2020, we filed a patent infringement complaint in the Western District of Texas against Intel Corporation (“Intel”) alleging infringement of eight of our patents. The complaint was amended in May 2020 to add two additional patents. In June 2020, we requested that one of the patents be dropped from this case and filed a second case in the Western District of Texas that included this dismissed patent (see ParkerVision v. Intel II below). Intel’s response to our complaint was filed in June 2020 denying infringement and claiming invalidity of the patents. Intel also filed a motion to transfer venue which the court denied. In July 2020 and September 2020, Intel filed IPR petitions against two of the patents in this case and in January 2021, the PTAB instituted proceedings with regard to these two petitions (see Intel v. ParkerVision (PTAB) below). The court issued its claim construction ruling in January 2021 in which the majority of the disputed claim terms were decided in our favor. The case was scheduled for trial beginning February 7, 2022. In April 2021, we filed an amended complaint to include additional Intel chips and products, including WiFi devices, to the complaint. The court suggested that, given the number of patents at issue, the case would be separated into two trials and, as a result of the added products, the first trial date was moved to June 2022. In January 2022, the PTAB issued its ruling on the IPRs (see Intel v. ParkerVision (PTAB) below). In February 2022, the parties filed a joint motion with respect to both Intel cases whereby the first case would be narrowed to six total patents asserted against Intel cellular products. These same six patents would be also asserted in the second Intel case, along with one additional patent from the second case, against Intel WiFi and Bluetooth products. As a result of the restructuring of the two cases, the trial date was moved to October 2022. In March 2022, due to discovery delays, the court agreed to move the trial commencement date to December 5, 2022. Discovery is ongoing in this case. We are represented in this case on a full contingency fee basis. ParkerVision v. Intel II (Western District of Texas) In June 2020, to reduce the number of claims in ParkerVision v. Intel, we filed a second patent infringement complaint in the Western District of Texas against Intel that included a single patent that we voluntarily dismissed from the original case. In July 2020, we amended our complaint adding two more 47 patents to the case. Intel responded to the complaint denying infringement and claiming invalidity of the patents. In January 2021, Intel filed a petition for IPR against one of the patents in this case and in July 2021, the PTAB instituted proceedings with regard to this petition (see Intel v. ParkerVision (PTAB) below). We filed an amended complaint in 2021 adding Intel WiFi and Bluetooth products to the case. Two claim construction hearings were held in June 2021 and July 2021 and the court’s claim construction ruling was largely decided in our favor. The case was scheduled for trial in October 2022. In February 2022, the parties filed a joint motion which provided that the Intel II case would assert the same six patents from the first Intel case, provided none of the patents were invalidated in the first case, as well as one additional patent, depending on the outcome of the pending IPR proceeding. As a result of the restructuring of the cases, the trial date for this case is rescheduled for May 2023 although this date may change in lieu of the schedule changes in the first Intel case. We are represented in this case on a full contingency fee basis. Additional Patent Infringement Cases – Western District of Texas ParkerVision filed a number of additional patent cases in the Western District of Texas in September and October 2020 including cases against (i) TCL Industries Holdings Co., Ltd, a Chinese company, TCL Electronics Holdings Ltd., Shenzhen TCL New Technology Co., Ltd, TCL King Electrical Appliances (Huizhou) Co., Ltd., TCL Moka Int’l Ltd. and TCL Moka Manufacturing S.A. DE C.V. (collectively “TCL”), (ii) Hisense Co., Ltd. and Hisense Visual Technology Co., Ltd (collectively “Hisense”), a Chinese company, (iii) Buffalo Inc., a Japanese company (“Buffalo”) and (iv) Zyxel Communications Corporation, a Chinese multinational electronics company headquartered in Taiwan, (“Zyxel”). Each case alleges infringement of the same ten patents by products that incorporate modules containing certain WiFi chips manufactured by Realtek and/or MediaTek. Each of the defendants have filed responses denying infringement and claiming invalidity of the patents, among other defenses. In May 2021, we filed a patent infringement case against LG Electronics (“LGE”), a South Korean company, in the Western District of Texas alleging infringement of the same ten patents. A second action was filed against Hisense in June 2021 in the Western District of Texas for infringement of two additional patents. In September 2021, we dismissed the cases against Buffalo and Zyxel following satisfaction of the parties’ obligations under settlement and license agreements entered into in May 2021 and September 2021, respectively. In May 2021, TCL and Hisense filed petitions for IPR against two of the ten patents asserted against them, including U.S. Patent 7,110,444 (“the ‘444 Patent”) which was challenged by Intel (see TCL, et. al. v. ParkerVision (PTAB) below). In December 2021, LGE filed nearly identical petitions for IPR against the same two patents along with a joinder motion requesting to join the existing petitions. The court held a combined Markman hearing on October 27, 2021 for the cases against Hisense and TCL. The court issued its claim construction recommendations on October 29, 2021, in which nearly all of the claim terms were decided in our favor. The Hisense and TCL cases currently have a trial date scheduled for December 12, 2022. The LGE case currently has a claim construction hearing scheduled for April 25, 2022 and a trial scheduled to commence on April 24, 2023. We are represented in each of these cases on a full contingency fee basis. Intel v. ParkerVision (PTAB) Intel filed petitions for Inter Partes Review (IPR) against U.S. patent 7,539,474 (“the ‘474 Patent”), and the ‘444 Patent which were both asserted in ParkerVision v. Intel. Intel also filed a petition for IPR against U.S. patent 8,190,108 (“the ‘108 patent”) which is asserted in ParkerVision v. Intel II. In January 2021, the PTAB issued its decision to institute IPR proceedings for the ‘444 Patent and the ‘474 Patent. An oral hearing was held on November 1, 2021 and final decisions from the PTAB on the ‘474 Patent and 48 the ‘444 Patent were issued in January 2022. The PTAB ruled against us with respect to the single challenged claim of the ‘444 Patent and ruled in our favor with respect to the seven challenged claims of the ‘474 Patent. The ‘444 Patent has subsequently been excluded from the narrowed claims asserted in ParkerVision v. Intel. In July 2021, the PTAB issued its decision to institute IPR proceedings for the ‘108 Patent. We filed our response to this petition in October 2021 and an oral hearing is scheduled for April 2022. A final decision from the PTAB with respect to the ‘108 Patent is expected by July 2022. Depending on the PTAB’s ruling with respect to the ‘108 Patent, we have the option to include or exclude this patent from the patents being asserted in the Intel II case. TCL, et. al. v. ParkerVision (PTAB) In May 2021, TCL, along with Hisense, filed petitions for Inter Partes Review (“IPR”) against U.S. patent 7,292,835 (“the ‘835 Patent”) and the ‘444 Patent, both of which are asserted in the infringement cases against these parties in the Western District of Texas. In November 2021, the PTAB issued its decision to implement IPR proceedings for these two patents. In December 2021, LGE filed nearly identical petitions against the same two patents along with a joinder motion requesting to join the existing petitions filed by TCL and Hisense. Oral hearings are scheduled for these IPRs in September 2022 with a final decision expected in November 2022. 13. STOCK AUTHORIZATION AND ISSUANCE Preferred Stock We have 15 million shares of preferred stock authorized for issuance at the direction of our board of directors (the “Board”). On November 17, 2005, our Board designated 0.1 million shares of authorized preferred stock as the Series E Preferred Stock in conjunction with its adoption of a Shareholder Protection Rights Agreement. As of December 31, 2021, we had no outstanding preferred stock. Common Stock We have 150 million shares of common stock authorized for issuance as of December 31, 2021.

Net proceeds are inclusive of the value of the CPRs that are classified as long-term debt (see Note 9). Private Placements In January 2020, we entered into securities purchase agreements with accredited investors for an aggregate of 1,169,232 shares of our common stock at a price of $0.13 per share and 166,667 shares of our common stock at $0.15 per share for aggregate proceeds of approximately $0.2 million. In March 2020, we entered into securities purchase agreements with accredited investors for an aggregate of 2,571,432 shares of our common stock at a price of $0.35 per share for aggregate proceeds of $0.9 million. The securities purchase agreements for the March 2020 transactions were amended on May 1, 2020, in order to add a contingent payment right whereby we will pay each investor an allocated portion of our share of proceeds from patent-related actions, after taking into account fees and expenses payable to law firms representing us and amounts payable to Brickell, up to an amount equal to the investors’ aggregate subscription amount, or $0.9 million (see “Unsecured Contingent Payment Obligations” in Note 9). The shares were registered for resale on a registration statement that was declared effective on April 28, 2020 (File No. 333-237762). From April to December 2020, we entered into securities purchase agreements with accredited investors for an aggregate of 10,857,876 shares of our common stock at a price of $0.35 per share for aggregate proceeds of $3.8 million. The securities purchase agreements include contingent payment rights. Approximately $1.8 million of the proceeds were allocated to unsecured contingent payment obligations based on the initial fair value estimate of the CPRs (see “Unsecured Contingent Payment Obligations” in Note 9). The shares sold from April to August, totaling 5,871,584 shares, were registered for resale on a registration statement that was declared effective on September 2, 2020 (File No. 333-248242). The shares sold from August to December, totaling 4,986,292 shares, were registered for resale on a registration statement that was declared effective on April 26, 2021 (File No. 333-255217). 50 In January 2021, we entered into securities purchase agreements with accredited investors for the sale of an aggregate of 2,976,430 shares of our common stock at a price of $0.35 per share for aggregate proceeds of $1.0 million. The securities purchase agreements include contingent payment rights. Approximately $0.4 million of the proceeds were allocated to unsecured contingent payment obligations based on the initial fair value estimate of the CPRs (see “Unsecured Contingent Payment Obligations” in Note 9). The shares were registered for resale on a registration statement that was declared effective on April 26, 2021 (File No. 333-255217). In March 2021, we entered into securities purchase agreements with accredited investors for the sale of 3,230,942 shares of our common stock and 1,619,289 warrants at a price of $1.29 per common share for aggregate proceeds of approximately $4.2 million. The warrants have an exercise price of $1.75 per share and expire in March 2026. The shares, including the shares underlying the warrants, were registered for resale on a registration statement that was declared effective on April 26, 2021 (File No. 333-255217). We used $3.0 million of the proceeds from this transaction to satisfy our obligations to Mintz (see “Secured Note Payable” in Note 9). In December 2021, we entered into a securities purchase agreement with an accredited investor for the sale of 1,052,631 shares of our common stock and 526,315 warrants at a price of $0.95 per common share for aggregate proceeds of $1.0 million. The warrants have an exercise price of $1.00 per share and expire in December 2026. The shares, including the shares underlying the warrants, were registered for resale on a registration statement that was declared effective on January 24, 2022 (File No. 333-262147). Warrant Amendment On February 28, 2020, we entered into a warrant amendment agreement (the “Warrant Amendment Agreement”) with Aspire Capital Fund, LLC (“Aspire”), with respect to warrants issued in July and September 2018 (the “2018 Warrants”) that are exercisable, collectively, into 5,000,000 shares of our common stock. The Warrant Amendment Agreement provided for a reduction in the exercise price for the 2018 Warrants from $0.74 to $0.35 per share and the issuance of a new warrant for the purchase of 5,000,000 shares of our common stock at an exercise price of $0.74 per share (“New Aspire Warrant”). The New Aspire Warrant expires February 28, 2025 and is subject to adjustment in the event of certain stock dividends and distributions, stock splits, stock combinations, reclassifications or similar events affecting our common stock and upon any distributions of assets to our stockholders. The New Aspire Warrant contains provisions that prohibit exercise if the holder, together with its affiliates, would beneficially own in excess of 9.99% of the number of shares of common stock outstanding immediately after giving effect to such exercise. The holder of the New Aspire Warrant may increase (up to 19.99%) or decrease this percentage by providing at least 61 days’ prior notice to the Company. In the event of certain corporate transactions, the holder of the New Aspire Warrant will be entitled to receive, upon exercise of such New Aspire Warrant, the kind and amount of securities, cash or other property that the holder would have received had they exercised the New Aspire Warrant immediately prior to such transaction. The New Aspire Warrant does not contain voting rights or any of the other rights or privileges as a holder of our common stock. We recognized $1.78 million of non-cash warrant expense in connection with the Warrant Amendment Agreement based on the difference between the Black-Scholes value of the warrants immediately before and after the amendment. The Warrant Amendment Agreement added a call provision to the 2018 Warrants whereby we could, after December 31, 2020, call for cancellation of all or any portion of the 2018 Warrants for which an exercise notice has not yet been received, in exchange for consideration equal to $0.001 per warrant share and subject to certain conditions. All other terms of the 2018 Warrants remained unchanged, including the original expiration dates of July and September 2023. The shares underlying the New Aspire Warrant were registered for resale on a registration statement that was 51 declared effective on April 28, 2020 (File No. 333-237762). The shares underlying the 2018 Warrants are currently registered for resale pursuant to a registration statement on Form S-1 (File No. 333-226738). Upon execution of the Warrant Amendment Agreement, Aspire exercised 1,430,000 shares of the 2018 Warrants for aggregate proceeds to us of $0.5 million. For the years ended December 31, 2021 and 2020, Aspire exercised 500,000 and 3,070,000 shares of the 2018 Warrants for aggregate additional proceeds to us of approximately $0.2 and $1.1 million, respectively. Stock and Warrant Issuances – Payment for Services On February 10, 2020, we entered into a business consulting and retention agreement with Chelsea Investor Relations (“Chelsea”) to provide business advisory services to us. As consideration for services to be provided under the 24-month term of the consulting agreement, we issued 500,000 shares of unregistered common stock in exchange for a nonrefundable retainer for services valued at approximately $0.15 million. The value of the stock issued is being recognized as consulting expense over the term of the agreement. The shares were registered for resale on a registration statement that was declared effective on April 28, 2020 (File No. 333-237762). In January 2021, we amended the agreement with Chelsea to increase the compensation for services over the remaining term and to extend the term of the agreement through February 2024. As consideration for the amended agreement, we issued 500,000 shares of unregistered common stock in exchange for a nonrefundable retainer for services valued at approximately $0.33 million. The value of the stock issued is being recognized as consulting expense over the term of the agreement. The shares were registered for resale on a registration statement that was declared effective on April 26, 2021 (File No. 333-255217). On March 16, 2020, we entered into an agreement with Tailwinds Research Group LLC (“Tailwinds”) to provide digital marketing services to us. As consideration for services to be provided under the twelve-month term of the agreement, we issued warrants for the purchase up to 200,000 shares of our common stock with an exercise price of $1.00 per share in exchange for a nonrefundable retainer for services, valued using the Black-Scholes method, at approximately $0.06 million. The value of the warrants was recognized as expense over the twelve-month term of the agreement. The Tailwinds warrants are exercisable immediately after issuance, expire March 16, 2023, and are subject to adjustment in the event of certain stock dividends and distributions, stock splits, stock combinations, reclassifications or similar events affecting our common stock. The shares underlying the warrant were registered for resale on a registration statement that was declared effective on April 28, 2020 (File No. 333-237762). On May 22, 2020, we entered into an agreement with Intro-Act to provide research and shareholder relations services. As consideration for services under the agreement, we issued 50,000 shares of unregistered common stock on each of July 14, 2020, October 30, 2020, January 12, 2021 and April 6, 2021 with an aggregate value of approximately $0.05 million for the year ended December 31, 2020 and $0.1 million for the year ended December 31, 2021. In June 2021, we extended our agreement with Intro-Act and issued 100,000 shares of unregistered common stock valued at approximately $0.12 million as consideration for services to be provided over the twelve-month extended term of the agreement. The value of the shares will be recognized as consulting expense over the term of the agreement. We are not obligated to register the shares for resale. On June 8, 2020, we entered into an agreement with a third party to provide media advisory services. As consideration for services provided under the term of the agreement, which extended through December 31, 2020, we issued 30,000 shares of unregistered common stock for a nonrefundable retainer for services valued at approximately $0.01 million. The value of the stock issued was recognized as a consulting expense over the term of the agreement. The shares were registered for resale on a registration statement that was declared effective on April 26, 2021 (File No. 333-255217). 52 On October 30, 2020, we entered into a consulting services agreement with a third-party to provide shareholder relations services. As consideration for services provided under the twelve-month term of the agreement, we issued 70,000 shares of unregistered common stock for a non-refundable retainer for services valued at approximately $0.02 million. The agreement included a CPR to receive up to $0.02 million from patent-related proceeds. The CPR was recorded as debt at its estimated fair value of approximately $0.1 million (see “Unsecured Contingent Payment Obligations” in Note 9). In April 2021, we amended the consulting services agreement and extended the term through December 31, 2021. We issued 35,000 shares of our unregistered common stock valued at approximately $0.04 million as compensation over the remaining term of the agreement. The value of the shares issued were recognized as consulting expense over the term of the agreement. In addition, from time to time, we issue restricted stock awards under our approved equity plans to third party consultants as share-based compensation. During the year ended December 31, 2021, we issued 217,143 RSAs valued at $0.3 million under our 2019 long-term incentive equity plan to nonemployees as compensation under consulting agreements (see Note 14). Common Stock Warrants As of December 31, 2021 and 2020, we had outstanding warrants for the purchase of up to 10.3 million shares and 12.9 million shares of our common stock, respectively. The estimated grant date fair value of these warrants of $3.2 million and $1.7 million at December 31, 2021 and 2020, respectively, is included in shareholders’ deficit in our consolidated balance sheets. As of December 31, 2021, our outstanding warrants have an average exercise price of $0.75 per share and a weighted average remaining life of approximately three years. Shareholder Protection Rights Agreement On November 20, 2020, we adopted a second amendment to our Shareholder Protection Rights Agreement (“Rights Agreement”) dated November 21, 2005, as amended. The amendment extends the expiration date of the Rights Agreement from November 20, 2020 to November 20, 2023 and decreases the exercise price of the rights from $14.50 to $8.54. The Rights Agreement provided for the issuance, on November 29, 2005, as a dividend, rights to acquire fractional shares of Series E Preferred Stock. We did not assign any value to the dividend, as the value of these rights is not believed to be objectively determinable. The principal objective of the Rights Agreement is to cause someone interested in acquiring us to negotiate with our Board rather than launch an unsolicited or hostile bid. The Rights Agreement subjects a potential acquirer to substantial voting and economic dilution. Each share of common stock issued by ParkerVision will include an attached right. The rights initially are not exercisable and trade with the common stock of ParkerVision. In the future, the rights may become exchangeable for shares of Series E Preferred Stock with various provisions that may discourage a takeover bid. Additionally, the rights have what are known as “flip-in” and “flip-over” provisions that could make any acquisition of us more costly to the potential acquirer. The rights may separate from the common stock following the acquisition of 15% or more of the outstanding shares of common stock by an acquiring person. Upon separation, the holder of the rights may exercise their right at an exercise price of $8.54 per right (the “Exercise Price”), subject to adjustment and payable in cash. Upon payment of the Exercise Price, the holder of the right will receive from us that number of shares of common stock having an aggregate market price equal to twice the Exercise Price, as adjusted. The Rights Agreement also has a flip over provision allowing the holder to purchase that number of shares of common/voting equity of a successor entity, if we are not the surviving corporation in a business combination, at an aggregate market price equal to twice the Exercise Price. We have the right to substitute for any of our shares of common stock that we are obligated to issue, shares of Series E Preferred Stock at a ratio of one ten- thousandth of a share of Series E Preferred Stock for each share of 53 common stock. The Series E Preferred Stock, if and when issued, will have quarterly cumulative dividend rights payable when and as declared by the Board, liquidation, dissolution and winding up preferences, voting rights and will rank junior to other securities of ParkerVision unless otherwise determined by the Board. The rights may be redeemed upon approval of the Board at a redemption price of $0.01. As of December 31, 2021, there are no Series E preferred shares outstanding. 14. SHARE-BASED COMPENSATION For the years ended December 31, 2021 and 2020 we recognized share-based compensation expense of approximately $3.3 million and $1.2 million, respectively. Share-based compensation is included in selling, general, and administrative expenses in our consolidated statements of comprehensive loss. From time to time, we issue fully vested share-based compensation awards to third parties as prepaid retainers for services over a specified period. The cost of these awards is recorded as a prepaid asset and expensed to selling, general and administrative expense over the service period (see Note 4). As of December 31, 2021, there was $3.0 million of total unrecognized compensation cost related to all non-vested share-based compensation awards. That cost is expected to be recognized over a weighted-average period of approximately 1.0 year. Stock Incentive Plans 2019 Long-Term Incentive Equity Plan We adopted a long-term incentive equity plan in August 2019 that provides for the grant of stock-based awards to employees, officers, directors and consultants, not to exceed 12.0 million shares of common stock (the “2019 Plan”). The 2019 Plan provides for benefits in the form of nonqualified stock options, stock appreciation rights, restricted stock awards, and other stock based awards. Forfeited and expired options under the 2019 Plan become available for reissuance. The plan provides that non-employee directors may not be granted awards that exceed the lesser of 1.0 million shares or $175,000 in value, calculated based on grant-date fair value. In January 2021, the Board amended the 2019 Plan to increase the number of shares of common stock reserved for issuance under the 2019 Plan from 12 million to 27 million shares. At December 31, 2021, 1,897,857 shares of common stock were available for future grants under the 2019 Plan. 2011 Long-Term Incentive Equity Plan We adopted a long-term incentive equity plan in September 2011 that, as amended in 2014, 2016 and 2017, provides for the grant of stock- based awards to employees, officers, directors and consultants, not to exceed 3.0 million shares of common stock (the “2011 Plan”). The 2011 Plan provides for benefits in the form of incentive stock options, nonqualified stock options, stock appreciation rights, restricted stock awards, and other stock based awards. Forfeited and expired options under the 2011 Plan become available for reissuance. The plan provides that no participant may be granted awards in excess of 150,000 shares in any calendar year. At December 31, 2021, 61,302 shares of common stock were available for future grants under the 2011 Plan. 2008 Equity Incentive Plan We adopted an equity incentive plan in August 2008 (the “2008 Plan”). The 2008 Plan provides for the grant of stock-based awards to employees (excluding named executives), directors and consultants, not to exceed 50,000 shares of common stock. The 2008 Plan provides for benefits in the form of incentive stock options, nonqualified stock options, stock appreciation rights, restricted stock awards, and other stock based awards. Forfeited and expired options under the 2008 Plan become available for reissuance. The plan provides that no participant may be granted awards in excess of 5,000 shares in any calendar year. At December 31, 2021, 20,473 shares of common stock were available for future grants under the 2008 Plan. 54 Restricted Stock Awards RSAs are issued as executive and employee incentive compensation and as payment for services to others. The value of the award is based on the closing price of our common stock on the date of grant. RSAs are generally immediately vested. Restricted Stock Units RSUs are issued as incentive compensation to executives, employees, and non-employee directors. Each RSU represents a right to one share of our common stock, upon vesting. The RSUs are not entitled to voting rights or dividends, if any, until vested. RSUs generally vest over a one to three year period for employee awards and a one year period for non-employee director awards. The fair value of RSUs is generally based on the closing price of our common stock on the date of grant and is amortized to share-based compensation expense over the estimated life of the award, generally the vesting period. RSAs and RSUs The following table presents a summary of RSA and RSU activity under the 2008, 2011, and 2019 Plans (collectively, the “Stock Plans”) as of December 31, 2021 (shares in thousands): Non-vested at beginning of year Granted Vested Forfeited Non-vested at end of year Non-vested Shares Shares Weighted-Average Grant Date Fair Value 187 217 (404) - - $ $ 0.33 1.34 0.87 - - The awards granted under the Stock Plans in 2021 were all RSAs awarded to non-employees as compensation in connection with consulting agreements. The total fair value of RSAs and RSUs vested under the Stock Plans for the year ended December 31, 2021 was approximately $0.6 million. Stock Options Stock options are issued as incentive compensation to executives, employees and non-employee directors. Stock options are generally granted with exercise prices at or above fair market value of the underlying shares at the date of grant. The fair value of options granted is estimated using the Black-Scholes option pricing model. Generally, fair value is determined as of the grant date. Options for employees, including executives and non-employee directors, are generally granted under the Stock Plans. 55 The following table presents a summary of option activity under the Stock Plans for the year ended December 31, 2021 (shares in thousands): Outstanding at beginning of year Granted Exercised Forfeited/Expired Outstanding at end of year Vested at end of year Shares 12,240 $ 13,040 (2,029) (36) 23,215 16,676 $ Weighted- Average Exercise Price Weighted-Average Remaining Contractual Term Aggregate Intrinsic Value ($) 0.28 0.54 0.17 11.18 0.42 0.37 4.2 years 4.3 years $ $ 11,988 9,503 In January 2021, the Board awarded 11.9 million nonqualified stock options to executives and other key employees and an aggregate of 1.1 million nonqualified stock options to non-employee directors under the 2019 Plan. The options are exercisable at $0.54 per share, vest in eight equal quarterly installments commencing March 31, 2021, and expire on January 11, 2026. The weighted average per share fair value of options granted during the years ended December 31, 2021 and 2020 was $0.46 and $0.27, respectively. The total fair value of option shares vested was $3.4 million and $0.9 million for the year ended December 31, 2021 and 2020, respectively. The fair value of option grants under the Stock Plans for the years ended December 31, 2021 and 2020, respectively, was estimated using the Black-Scholes option-pricing model with the following assumptions: Expected option term 1 Expected volatility factor 2 Risk-free interest rate 3 Expected annual dividend yield Year ended December 31, 2021 4 years 141.1% 0.36% 0% 2020 5 years 127.4% to 135.3% 0.33% to 1.63% 0% 1 The expected term was generally determined based on historical activity for grants with similar terms and for similar groups of employees and represents the period of time that options are expected to be outstanding. For employee options, groups of employees with similar historical exercise behavior are considered separately for valuation purposes. 2 The stock volatility for each grant is measured using the weighted average of historical daily price changes of our common stock over the most recent period equal to the expected option life of the grant. 3 The risk-free interest rate for periods equal to the expected term of the share option is based on the U.S. Treasury yield curve in effect at the measurement date. 56 Options by Price Range The options outstanding at December 31, 2021 under all plans have exercise price ranges, weighted average contractual lives, and weighted average exercise prices as follows (weighted average lives in years and shares in thousands): Range of Exercise Prices $0.171 - $0.33 $0.50 - $0.75 $1.98 - $2.97 Options Outstanding Options Vested Number Outstanding at December 31, 2021 Wtd.

We had no option exercises for the year ended December 31, 2020. 15. RELATED PARTY TRANSACTIONS We paid approximately $0.1 million and $0.01 million in 2021 and 2020, respectively, for patent-related legal services to SKGF, of which Robert Sterne, one of our directors since September 2006, is a partner. In addition, we paid approximately $0.1 million in both 2021 and 2020 for principal and interest on the SKGF Note (refer to “Note Payable to a Related Party” included in Note 9). The SKGF Note has an outstanding balance, including accrued interest, of approximately $0.7 million at December 31, 2021. In January 2020, we issued 500,000 in unregistered shares of our common stock as an in-kind payment of approximately $0.08 million in outstanding amounts payable to Stacie Wilf, sister to Jeffrey Parker. 16. CONCENTRATIONS OF CREDIT RISK Financial instruments that potentially subject us to a concentration of credit risk principally consist of cash and cash equivalents. Cash and cash equivalents are primarily held in bank accounts and overnight investments. At times our cash balances on deposit with banks may exceed the balance insured by the F.D.I.C. 17. SUBSEQUENT EVENTS On March 22, 2022, the United States District Court in the Middle District of Florida (Orlando Division) issued an order granting Qualcomm’s motion for summary judgment ruling that Qualcomm does not infringe the three patents that are the subject of our infringement case against them. This ruling, which is a final determination of the district court, follows a March 9, 2022 order granting a Qualcomm motion to strike and exclude the opinions of our experts regarding the alleged infringement and validity issues. We intend to appeal both of these decisions. See ParkerVision v. Qualcomm (Middle District of Florida) included in Note 12 for a complete discussion of these legal proceedings. 57 In February 2022, our two patent infringement cases against Intel in the Western District of Texas were reconfigured whereby the first case would assert an aggregate of six patents against Intel cellular products and the second case would assert the same six patents along with a seventh patent against Intel WiFi and Bluetooth products. As a result of the restructuring of the cases, the trial date for the first Intel case was moved from June 2022 to October 24, 2022. In March 2022, as a result of discovery delays, the trial date was moved to a start date of December 5, 2022. The second case against Intel is currently scheduled for trial commencing in May 2023, however that date may change in lieu of the revised schedule in the first Intel case. See ParkerVision v. Intel (Western District of Texas) and ParkerVision v. Intel II (Western District of Texas) included in Note 12 for a complete discussion of these legal proceedings. In January 2022, the Patent Trial and Appeal Board (“PTAB”) issued its final decisions on two Inter Partes Reviews (“IPRs”) filed by Intel against two of the patents asserted in the ParkerVision v. Intel infringement cases. The PTAB ruled in our favor with respect to the seven challenged claims of one of the two patents and ruled in Intel’s favor with respect to the one challenged claim of the second patent. We have one additional IPR filed by Intel against a patent asserted in our second case, and the PTAB is expected to issue its final decision in July 2022. Refer to Intel v. ParkerVision (PTAB) included in Note 12 for a complete discussion of these IPR proceedings. 58 Item 9. Changes in and Disagreements with Accountants on Accounting and Financial Disclosure. None. Item 9A. Controls and Procedures. Evaluation of Disclosure Controls and Procedures Under Rules 13a-15(e) and 15d-15(e) of the Exchange Act, “disclosure controls and procedures” are controls and other procedures that are designed to ensure that the information we are required to disclose in reports that we file or submit under the Exchange Act is recorded, processed, summarized and reported within the time periods specified under the rules and forms of the SEC. Disclosure controls and procedures include, without limitation, controls and procedures designed to ensure that such information is accumulated and communicated to our management, including our chief executive officer and our chief financial officer, as appropriate to allow timely decisions regarding required disclosures. Our management, with the participation of our chief executive officer and our chief financial officer, has evaluated the effectiveness of our disclosure controls and procedures as of December 31, 2021. Based on such evaluation, our chief executive officer and our chief financial officer have concluded that as of December 31, 2021, our disclosure controls and procedures were effective. Management’s Report on Internal Control over Financial Reporting Our management is responsible for establishing and maintaining adequate internal control over financial reporting and for the assessment of the effectiveness of internal control over financial reporting. Under Rules 13a-15(f) and 15d-15(f) of the Exchange Act, “internal control over financial reporting’’ is defined as a process designed by, or under the supervision of, our chief executive officer and our chief financial officer, and effected by our board of directors, management and other personnel, to provide reasonable assurance regarding the reliability of our financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. Internal control over financial reporting includes policies and procedures that pertain to the maintenance of records, that in reasonable detail, accurately and fairly reflect our transactions and our dispositions of assets; provide reasonable assurance that transactions are recorded as necessary to permit preparation of our financial statements in accordance with generally accepted accounting; provide reasonable assurance that receipts and expenditures of the Company are made only in accordance with authorizations of management and directors; and provide reasonable assurance regarding the prevention or the timely detection of the unauthorized acquisition, use or disposition of the Company’s assets that could have a material effect on our 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 and procedures may deteriorate. Management, with the participation of our chief executive officer and our chief financial officer, conducted an evaluation of the effectiveness of our internal control over financial reporting as of December 31, 2021 using the criteria established in Internal Control—Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission in 2013. Based on this evaluation, management concluded that our internal control over financial reporting was effective as of December 31, 2021. 59 Changes in Internal Control over Financial Reporting There were no changes in our internal control over financial reporting during the fiscal quarter ended December 31, 2021 that materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

The note, as amended, allows for interest at 4% per annum, monthly installments of $10,000 per month beginning January 2020, with a final balloon payment due on April 30, 2023. At December 31, 2021, the outstanding balance of the note, including unpaid interest is approximately $703,000. In January 2020, we issued 500,000 in unregistered shares of our common stock as an in-kind payment of approximately $0.08 million in outstanding amounts payable to Stacie Wilf, sister to Jeffrey Parker. Director Independence We follow the rules of Nasdaq in determining if a director is independent.

(the “Company”, “we”, “our” or similar terms) is based upon the Company’s amended and restated articles of incorporation (“Charter”), the Company’s bylaws (“Bylaws”) and applicable provisions of law. We have summarized certain portions of the Charter and Bylaws below. The summary is not complete and is subject to, and is qualified in its entirety by express reference to, the provisions of our Charter and Bylaws, each of which is filed as an exhibit to the Annual Report on Form 10-K of which this Exhibit 4.7 is a part. Authorized Capital Stock Pursuant to our Charter, our authorized capital stock consists of 165,000,000 shares, of which 150,000,000 is voting Common Stock, $0.01 par value per share, and 15,000,000 is Preferred Stock, $1.00 per share. Common Stock Authorization. The outstanding shares of the Company’s common stock are duly authorized, validly issued, fully paid and nonassessable. Listing. The Company’s common stock is traded on the OTCQB Market under the ticker symbol “PRKR.” Voting Rights. Common stockholders of record are entitled to one vote for each share held on all matters to be voted on by stockholders. Preemptive Rights, Etc. Our stockholders have no preemptive or other subscription rights. There are no sinking fund provisions applicable to our common stock, except that upon the consummation of our initial business combination, subject to the limitations described herein, we will provide our stockholders with the opportunity to redeem their shares of our common stock for cash equal to their pro rata share of the aggregate amount then on deposit in the trust account. Preferred Stock Our Charter provides that shares of preferred stock may be issued from time to time in one or more series. Our board of directors will be authorized to fix the voting rights, if any, designations, powers, preferences, the relative, participating, optional or other special rights and any qualifications, limitations and restrictions, applicable to the shares of each series. Our board of directors will be able, without stockholder approval, to issue preferred stock with voting and other rights that could adversely affect the voting power and other rights of the holders of the common stock and could have anti-takeover effects. Series E Preferred Stock On November 17, 2005, the board of directors designated 100,000 shares of authorized preferred stock as the Series E Preferred Stock in conjunction with its adoption of a Shareholder Protection Rights Plan (as described below). Certain rights of this series of preferred stock are defined in terms of a “Reference Package.” The “Reference Package” is initially 1,000 shares of common stock, as adjusted for stock dividends, subdivisions and combinations. The holders of full or fractional shares of this series are entitled to receive dividends, when and as declared by the board of directors, on each date that dividends or other distributions (other than dividends or distributions payable in our common stock) are payable on or in respect of common stock comprising part of the Reference Package, in an amount per whole share of this series equal to the aggregate amount of dividends or other distributions that would be payable on such date to a holder of the Reference Package. In addition, on the last day of March, June, September and December in each year, the holders of this series are entitled to receive dividends in an amount per whole share of this series equal to the excess (if any) of $100 over the aggregate dividends paid per whole share of this series during the three-month period ending on such last day. Dividends on each full and each fractional share of this series are cumulative from the date such full or fractional share is originally issued. In the event of any liquidation, dissolution or winding up of our affairs, whether voluntary or involuntary, the holders of full and fractional shares of this series shall be entitled, before any distribution or payment is made on any date to the holders of the common stock or any other stock of ours ranking junior to this series upon liquidation, to be paid in full an amount per whole share of this series equal to the greater of $100 or the aggregate amount distributed or to be distributed in connection with such liquidation, dissolution or winding up to a holder of the Reference Package, together with accrued dividends to such distribution or payment date, whether or not earned or declared. Our Series E Preferred Stock shall rank junior to all other series or classes of our preferred stock, now existing or hereafter created, as to payment of dividends and the distribution of assets, unless the terms of any such other series or class shall provide otherwise. Each whole share of this series shall, on any matter, vote as a class with any other capital stock comprising part of the Reference Package and voting on such matter and shall have the number of votes thereon that a holder of the Reference Package would have. Shareholder Protection Rights Plan We have a Shareholder Protection Rights Agreement (“Rights Agreement”), originally adopted on November 21, 2005 and amended on November 20, 2015 and November 20, 2020 pursuant to which we issued, on November 29, 2005, as a dividend, one right to acquire a fraction of a share of Series E Preferred Stock for each then outstanding share of Common Stock. Each share of Common Stock issued by us after such date also has included, and any subsequent shares of Common Stock issued by us prior to the Separation Time (as defined in the Rights Agreement) will include, an attached right. The following description of the Rights Agreement, and any description of the Rights Agreement included in a prospectus supplement, may not be complete and is subject to and qualified in its entirety by reference to the terms and provisions of the Rights Agreement. The principal objective of the Rights Agreement is to cause someone interested in acquiring us to negotiate with our Board rather than launch an unsolicited or hostile bid. The Rights Agreement subjects a potential acquirer to substantial voting and economic dilution. The rights initially are not exercisable and trade with our Common Stock. In the future, the rights may become exercisable with various provisions that may discourage a takeover bid. If a potential acquirer initiates a takeover bid or becomes the beneficial owner of 15% or more of our Common Stock, the rights will separate from the Common Stock. Upon separation, the holders of the rights may exercise their rights at an exercise price of $14.50 per right (the “Exercise Price”), subject to adjustment and payable in cash. Additionally, the rights have what are known as “flip-in” and “flip-over” provisions that could make any acquisition of us more costly to the potential acquirer. The “flip-in” provision provides that, in the event a potential acquirer acquires 15% or more of the outstanding shares of our Common Stock, upon payment of the exercise price, the holders of the rights will receive from us that number of shares of Common Stock having an aggregate market price equal to twice the Exercise Price, as adjusted. The “flip-over” provision allows the holder to purchase that number of shares of common/voting equity of a successor entity, if we are not the surviving corporation in a business combination, with an aggregate market price equal to twice the Exercise Price. We have the right to substitute for any of our shares of Common Stock that we are obligated to issue, shares of Series E Preferred Stock at a ratio of one thousandth of a share of Series E Preferred Stock for each share of Common Stock. The rights may be redeemed upon approval of the Board at a redemption price of $0.01 per right. The Rights Agreement expires on November 20, 2023. Classified Board; Director Nominations; Special Meetings Our Board is divided into three classes, with only one class of directors elected at each annual meeting, and our shareholders may remove our directors only for cause. Nominations for our Board may be made by our Board or by any holder of Common Stock. A shareholder entitled to vote for the election of directors may nominate a person for election as director only if the shareholder provides written notice of his nomination to our secretary not later than 120 days in advance of the same day and month that our proxy statement was released to shareholders in connection with the previous year’s annual meeting of shareholders or, if no annual meeting was held in the previous year, then by the end of the fiscal year to which the annual meeting in which the nomination will be made relates. A special meeting of our shareholders may be called only by our Board or our chief executive officer. These provisions and the Board’s right to issue shares of our preferred stock from time to time, in one or more classes or series without stockholder approval, are intended to enhance the likelihood of continuity and stability in the composition of the policies formulated by our Board. These provisions are also intended to discourage some tactics that may be used in proxy fights. CONSENT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM EXHIBIT 23.1 ParkerVision, Inc.

French Chief Financial Officer (Principal Financial Officer and Principal Accounting Officer) ParkerVision Reports 2021 Results JACKSONVILLE, Fla., March 29, 2022 – ParkerVision, Inc. (OTCQB: PRKR) (“ParkerVision”), a developer and marketer of technologies and products for wireless applications, today announced results for the year ended December 31, 2021. Year End 2021 Summary and Recent Developments · · · Patent license and settlement agreements were reached with Zyxel Communications Corporation and Buffalo, Inc. in 2021, resulting from the Company’s patent enforcement campaign initiated in the Western District of Texas in 2020. The U.S. District Court in the Middle District of Florida (Orlando Division) issued a summary judgment order on March 22, 2022 ruling that Qualcomm does not infringe the claims of the three patents in ParkerVision’s patent case against Qualcomm. o ParkerVision intends to appeal this ruling along with the same court’s March 9, 2022 ruling excluding the opinions of ParkerVision’s experts regarding infringement and validity issues. Two infringement cases against Intel in the Western District of Texas were reconfigured to include cellular products in the first case and WiFi and Bluetooth products in the second. o First Intel trial date against cellular products was moved from June 2022 to October 2022 as a result of this case reconfiguration and subsequently moved to December 5, 2022 due to discovery delays. o Second Intel trial date against Intel WiFi and Bluetooth products currently scheduled for May 2023. o Favorable Markman decisions received in both Intel cases during 2021. o One of the two IPRs filed by Intel related to patents in these cases was decided in the Company’s favor by the PTAB in January 2022. Third IPR filed by Intel pertaining to patent in second case is awaiting PTAB decision. · Additional enforcement actions pending in the Western District of Texas also include Hisense, TCL and LG with trials scheduled in December 2022 and April 2023. o Favorable Markman recommendations issued in Hisense and TCL cases in October 2021; Markman hearing scheduled for April 2022 in LG case. o IPR petitions were filed by Hisense and TCL against two of the ten patents asserted in these cases; LG has filed a request to join these pending proceedings. Decisions expected in November 2022. · Infringement cases against Qualcomm and Apple in the Middle District of Florida (Jacksonville) and LG in the District of New Jersey are stayed pending outcomes in other cases. Jeffrey Parker, Chairman and Chief Executive Officer, commented, “We are pleased to have resolved our outstanding patent actions with Zyxel and Buffalo as licensees of our technologies. We are hopeful that additional parties will join Zyxel and Buffalo and become licensees of our patented technologies in the near future under comparable royalty rates. The Texas court continues to move efficiently, and we believe the claim construction rulings to date demonstrate the merits of our claim construction positions. Our first of two infringement actions against Intel is scheduled for trial in approximately eight months and three additional trials are scheduled in Texas within five months following this first Intel trial. We look forward to presenting the facts of our cases to Texas juries.” Mr. Parker continued, “Recent rulings from the district court in Orlando are substantial blows to our pending action against Qualcomm as the court first excluded the opinions of our experts and subsequently issued a summary judgment ruling of non-infringement on the three remaining patents in the case. The next step is an appeal that we intend to vigorously pursue. We are hopeful that the appellate court will give proper weight to our positions which we feel are strongly supported by legal precedence. At a recent public hearing in the Orlando case against Qualcomm, I was surprised to hear the court comment, ‘We all know the jury isn’t going to follow 99% of what you all are talking about in this trial. They’re going to come up with a rough idea of who deserves to win, but the nuances of a patent case, there’s no way a jury understands this which is why this shouldn’t be tried to a jury, in my opinion. They will never understand. It should be PTAB 100%.’ The fact is that district courts with Article 3 judges represent the only venue available to patent holders for enforcing our patented rights. “This case has been pending in the district court in Orlando since 2014. It has survived multiple IPR challenges, a motion to move venue to California, and numerous other delays. We are disappointed with the additional delays these recent rulings will create; however, we remain confident in the merits of our case, and we are steadfast in our goal to hold Qualcomm accountable for their unauthorized, and we believe willful, use of our technologies.” Financial Results · Net loss for 2021 was $12.3 million, or $0.17 per common share, compared to a net loss of $19.6 million, or $0.42 per common share for 2020. o The 37% decrease in year-to-date net loss is a primarily the result of § § § a $2.3 million decrease in litigation fees and expenses largely related to our case against Qualcomm in Jacksonville, Florida which is currently stayed. the recognition in 2020 of approximately $2.2 million in noncash charges related to the modification of equity-related agreements with third parties. a $4.0 million decrease in the loss related to the change in fair value of our contingent payment obligations. § An offsetting $2.1 million increase in share-based compensation expense. · We used cash for operations of approximately $7.7 million in 2021 compared to approximately $4.8 million in cash used for operations in 2020. The increase is the result of a significant decrease in accounts payable and other current liabilities in 2021, resulting in a $3.7 million improvement in working capital. o Our use of cash in 2021 was funded by $6.2 million in net proceeds received from the sale of debt and equity securities and $1.0 million in proceeds received from the exercise of outstanding options and warrants.
