ParkerVision completes appeal briefing in case against Qualcomm

ParkerVision (PRKR) announced that it has completed appellate briefing in its appeal of the Orlando district court’s claim construction ruling in its patent infringement case against Qualcomm (QCOM) – a ruling that forced ParkerVision to stipulate to non-infringement and seek expedited appellate review. In its final brief, ParkerVision highlights that a careful review of Qualcomm’s appellate filing reveals a critical contradiction that calls into question the basis of the non-infringement stipulation. “This is about fundamental fairness and consistency,” ParkerVision CEO Jeffrey Parker said. “For years now Qualcomm has argued that ParkerVision’s patent claims require down-conversion in a specific location and now in their own brief for the first time they claim that was never the argument. You can’t win a case based on a rule and then claim that rule never applied. Qualcomm has long held that they don’t infringe ParkerVision’s patents because they use switches for down-conversion. The patents in this case clearly use switches for down-conversion so now Qualcomm is trying to rewrite ParkerVision’s patents. Qualcomm’s own arguments show that this case deserves to be heard by a jury.”
