ParkerVision Inc (PRKR) is a semiconductor intellectual property company that develops and licenses radio frequency (RF) technologies for wireless communications. Revenue comes from patent licensing agreements and litigation settlements, all five of which, as of the FY2025 10-K filed 2026-03-23, resulted from patent enforcement actions rather than voluntary licensing. ParkerVision holds approximately 36 active U.S. and foreign patents related to RF technologies as of December 31, 2025, with over 70 additional patents expired in the prior eight years. The company pursues infringement claims against mobile handset, smart television, WiFi product, and semiconductor suppliers in U.S. district courts, with nine patent enforcement actions pending in the Western District of Texas as of the filing date. ParkerVision carries $3.1 million in convertible notes as of December 31, 2025, financed partly through convertible debt at fixed conversion prices ranging from $0.08 to $0.25 per share, and a $0.2 million unsecured note payable to related-party law firm Sterne, Kessler, Goldstein & Fox PLLC.
