Notes to Financial Statements
Nature of Operations [Text Block]	1. ParkerVision, Inc. and its wholly-owned German subsidiary, ParkerVision GmbH (collectively “ParkerVision”, “we” or the “Company”), is in the business of innovating fundamental wireless technologies and products. We have designed and developed proprietary radio frequency (“RF”) technologies and integrated circuits and license those 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 semiconductor suppliers for the infringement of a number of our RF patents. We have made significant investments in developing and protecting our technologies.

Earnings Per Share [Text Block]	6. Basic loss per common share is determined based on the weighted-average number of common shares outstanding during each period. Diluted loss per common share is the same as basic loss per common share as all common share equivalents are excluded from the calculation, as their effect is anti-dilutive. We have shares underlying outstanding options, warrants, and convertible notes that were excluded from the computation of diluted loss per share as their effect would have been anti-dilutive.

Long-Term Debt [Text Block]	9. Notes Payable Related Party Note Payable We have an unsecured promissory note of approximately $0.6 million payable to Sterne, Kessler, Goldstein, & Fox, PLLC (“SKGF”), a related party, for outstanding unpaid fees for legal services. As of September 30, 2022 April 2023 April 2027. April 2027. Convertible Notes Our convertible notes represent 5-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, 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 condensed consolidated financial statements.
