JACKSONVILLE, Fla., March 28, 2013 (GLOBE NEWSWIRE) -- With 211 domestic and international patents in its portfolio, ParkerVision, Inc. (Nasdaq:PRKR), leads the wireless sector in three broad categories measuring the value and impact of intellectual property, according to a new analysis from The Patent Board that appeared in the March 18, 2013 edition of The Wall Street Journal. ParkerVision ranked first in three of the six criteria used by The Patent Board to objectively analyze the influence of current patent portfolios maintained by wireless and telecom sector companies. The Patent Board's most recent "Patent Scorecard" ranked ParkerVision number one in "Research Intensity," "Science Strength" and "Industry Impact." The rankings, which are released by The Patent Board three times annually, position ParkerVision alongside such industry leaders as Qualcomm, Cisco, Motorola, Samsung, Nokia, Research In Motion, LG Electronics, Ericsson and others. ParkerVision, which was awarded 23 new domestic and international patents in 2012, has ranked first in two or more of The Patent Board's criteria for the last six reporting periods. In the current report, ParkerVision was also ranked first in "Science Strength" as analyzed by The Patent Board over a cumulative five-year period. "ParkerVision's portfolio is one of the finest we have ever evaluated at 3LP and during my 30 year career," said Kevin Rivette, managing partner of 3LP Advisors, a leading intellectual property advisory firm, and former V.P. of Intellectual Property Strategy at IBM. "In addition to the fundamental nature of the innovation, the crafting of this portfolio to have such breadth and depth of coverage is impressive and speaks to why it consistently makes the Patent Scorecard list," he added.
