JACKSONVILLE, Fla., Jan. 8, 2015 (GLOBE NEWSWIRE) -- ParkerVision, Inc. (Nasdaq:PRKR), a developer and marketer of semiconductor technology solutions for wireless applications, today announced that on January 8, 2015, the Patent Trial and Appeal Board ("PTAB") denied institution of trial of all challenged claims for Inter Partes review ("IPR") of ParkerVision patent 7,496,342 ("the '342 patent"). The IPR petition was filed in July, 2014 by RPX Corporation and Michael Farmwald against five claims of the '342 patent. The '342 patent is one of the four patents subject to ParkerVision's pending appeal in its patent infringement case against Qualcomm, Incorporated.  

Jeffrey Parker, Chairman and CEO, commented, "We applaud the PTAB's decision to deny this entire IPR petition. Both the district court and now the PTAB have rejected questions of validity with regard to this patent, and we believe that is an appropriate and just determination.   Claim 18 of the '342 patent is one of the eleven claims that a district court jury found to be infringed by Qualcomm. Denial of trial institution for this and all of the other challenged claims of the '342 patent is an extremely favorable disposition for ParkerVision in its ongoing legal battle with Qualcomm."
