ParkerVision's Patent Portfolio Leads Telecom Sector

Company Once Again Tops Independent Patent Score List in Three Technology

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.

Founded in 1968 as a patent analytics and research institution, The Patent
Board is the leading independent provider of best practices research, tools
and metrics for patent analysis and intellectual property investment. The
Patent Board tracks and analyzes innovation, movement, and the business value
of patent assets across every industry on a global basis. The Patent Scorecard
is a periodic assessment of patent activity and is primarily ranked by a
combined measure of the quality and quantity of a company's patent portfolio.
The Patent Board has developed more than 50 indicators that track global
patent activity relating to companies' innovation, technology, and science

According to The Patent Board's criteria, Science Strength is a measure of the
degree to which a company's patents are referenced in trade journal and
scholarly articles. Industry Impact is determined based on the influence that
a company's patents have on the broader industry. Research Intensity is an
aggregate measure of the degree to which a company's technology is building on
core science.

"From ParkerVision's inception, we have continuously sought new ways to
approach technological problems through innovation and the development of
novel yet practical solutions. The significant influence of the technologies
we have pioneered for wireless communication is evident in the patent
portfolio that we have built and continue to maintain," said ParkerVision
Chairman and CEO Jeffrey Parker. "We believe our technology is responsible for
important breakthroughs in the way mobile devices are used, and we expect our
continued innovations will result in ongoing expansion of our intellectual
property portfolio."
