ParkerVision Expands IP Portfolio With 23 New Patents In 2011

JACKSONVILLE, Fla., Feb. 8, 2012 /PRNewswire/ -- Wireless technology innovator ParkerVision, Inc. (Nasdaq: PRKR) is announcing a significant expansion of its wireless intellectual property portfolio following the issuance of 23 new patents during 2011. The company's portfolio now includes 188 domestic and international patents.

ParkerVision's intellectual property portfolio focuses on protecting its innovations in radio frequency (RF) communications. The company's advances in RF receiver and transmitter technology represent more than marginal improvements over traditional RF technology. ParkerVision's patents cover and protect fundamentally new RF technology that delivers essential improvements in performance, cost, size and functionality for mobile electronic devices.

"We believe these innovations have had a powerful impact and continue to enable major advancements in today's cellphone and tablet industries, while helping reset performance expectations in those markets for the future," says Jeffrey Parker, ParkerVision's CEO and Chairman.

The ParkerVision patents granted in 2011 build upon a body of intellectual property that already has received independent recognition for its strength and value by such organizations as The Patent Board and MDB Capital. The newly issued patents include improvements and expansions of ParkerVision's existing intellectual property related to RF down converters and up converters, the building blocks for RF receivers and transmitters. These patents further solidify the strength of ParkerVision's portfolio, giving ParkerVision the exclusive opportunity to license and commercialize its intellectual property.

ParkerVision adheres to a disciplined patent prosecution approach designed to maximize the opportunities for intellectual property commercialization, according to ParkerVision Chief Technology Officer David Sorrells. The company now owns patents issued in the United States, Canada, United Kingdom, Spain, Germany, France, Finland, Sweden, Japan, South Korea, Taiwan and Australia.

"ParkerVision has been at the forefront in the invention of new approaches designed from inception to meet the unique demands of today's complex RF waveforms and networks," Mr. Sorrells says. "It's no surprise to us that RF transmission and receiving techniques developed over the last 70 years are no longer keeping pace with technological advancements since those techniques simply did not contemplate the demands of today's wireless devices and networks."
