AI overview: The ParkerVision lawsuit against Qualcomm is a long-running patent infringement case that began in 2011, alleging that Qualcomm's wireless technology infringed on ParkerVision's patents for down-converting electromagnetic signals. While a jury initially ruled in favor of ParkerVision, the district court later overturned the verdict. In 2024, the U.S. Court of Appeals for the Federal Circuit reversed the lower court's ruling, sending the case back to the district court for further proceedings.

Key developments in the lawsuit




  • 2011:
    ParkerVision sues Qualcomm in the U.S. District Court for the Middle District of Florida for patent infringement.




  • 2013:
    A jury finds that Qualcomm infringed on ParkerVision's patents and awards $173 million in damages.




  • 2014:
    The district court overturns the jury's verdict and grants a judgment of non-infringement in favor of Qualcomm.




  • 2014:
    Following Qualcomm's disclosure of other infringing patents, ParkerVision files a second lawsuit against Qualcomm.




  • 2022:
    The district court issues a summary judgment ruling in favor of Qualcomm on infringement of two patents.




  • 2024:
    The U.S. Court of Appeals for the Federal Circuit reverses the 2022 summary judgment, ruling that the district court erred in its decision. The case is remanded back to the district court for trial on the remaining issues.




  • 2024:
    ParkerVision files a petition with the U.S. Supreme Court challenging the Federal Circuit's practice of summarily affirming administrative patent invalidations in separate cases.




  • 2025:
    The Supreme Court denies ParkerVision's petition for a writ of certiorari.




What the lawsuit is about




  • Patented technology:
    The lawsuit centers on ParkerVision's patents related to a system for down-converting high-frequency electromagnetic signals into a low-frequency or "baseband" signal.




  • Energy sampling:
    ParkerVision's technology uses a method called "energy sampling," which differs from the traditional "voltage sampling" method used in conventional down-converting systems.




  • Elimination of bulky components:
    A key benefit of ParkerVision's technology is that it eliminates the need for bulky and performance-impacting components like carrier I/Q combiners and splitters.
