In a blow to publicly traded NPE ParkerVision, Inc., the Patent Trial and Appeal Board (PTAB) has instituted inter partes review (IPR) of two of the entity’s patents in multiple proceedings filed by Qualcomm. In six separate decisions all issued on March 8, 2016, the PTAB instituted trial for over 60 claims of ParkerVision’s 6,091,940 patent, finding that Qualcomm had demonstrated a reasonable likelihood of showing that the challenged claims are invalid as obvious over prior art. That same day, the PTAB also instituted trial for a second patent (7,966,012), holding that Qualcomm had shown that it was likely to prevail on its assertion of obviousness for claims 1-3, 6, 8-10, and 13-18. However, in another set of rulings on March 8, the Board declined to institute trial for three Qualcomm petitions (IPR2015-01819, IPR2015-01822, IPR2015-01825) seeking review of a third ParkerVision patent (7,039,372). The three patents generally relate to direct conversion of RF signals.
