As in Complaint:
ParkerVision alleged that Qualcomm infringed the claims of the patent-in-suit by using energy sampling in the integrated circuits of various receiver and transceiver products that Qualcomm sells to original equipment manufacturers (OEM), who incorporates those products in mobile communication devices such as smartphones. The suit named a few Qualcomm’s transceiver chips such as Astra, Bahama, Eagleray, Halley, Hercules, Iceman, Iris, etc. that are used in phones and other electronic devices.
ParkerVision demanded Court to enter judgment in favor and issue an order blocking Qualcomm from using the patented technology or award compensatory damages and a reasonable royalty.  
Case Proceedings:
According to Court documents, Qualcomm denied that it infringed ParkerVision’s patents and contended that the patents are invalid.
The parties filed motions for summary judgment regarding validity (filed by ParkerVision) and non-infringement (filed by Qualcomm). However, court denied the parties’ respective motions for summary judgment. A jury trial was held in Oct 2013 and the jury returned verdict rejecting Qualcomm’s invalidity claims and finding that Qualcomm infringed the ’551, ‘518, ‘371 and ‘342 patents. Following the jury verdict, Qualcomm moved for judgment as a matter of law (JMOL) concerning invalidity and non-infringement. In May 2014, the court held a hearing and granted Qualcomm’s non-infringement motion. Accordingly, in Jun 2014, judgment was rendered in favor of Qualcomm against ParkerVision.
ParkerVision has filed an appeal as district court’s judgment was not in their favor.
