PLANO, Texas--(BUSINESS WIRE)--
ContentGuard Holdings, Inc. ("ContentGuard"), a subsidiary of Pendrell
Corporation (NASDAQ:PCO), announced that on Friday, March 20, 2015,
Judge J. Rodney Gilstrap of the U.S. District Court for the Eastern
District of Texas issued a 144 page Claim Construction Order in lawsuits
ContentGuard filed against several companies who continue to use its
patented Digital Rights Management ("DRM") solutions without a license,
including Apple, Amazon.com, DirecTV, Google, HTC, Huawei, Motorola
Mobility and Samsung Electronics.
In his order, Judge Gilstrap interpreted the language in ContentGuard's
patents in a manner that fully preserves the breadth of ContentGuard's
patented Digital Rights Management ("DRM") technologies. These
technologies were developed to enable the distribution of digital media
over the Internet and other networks, including cellular and satellite
networks, and provide innovative solutions to problems that were once
thought to be unsolvable.
"We are very pleased with the Court's ruling," commented James Baker,
ContentGuard's Vice President for Licensing and Strategic Development.
"We believe these claim constructions demonstrate that the online stores
defendants provide for buying and renting DRM-protected movies, videos,
books, and music (including the Google Play, Amazon Kindle, and iTunes
stores), and devices that play, run, display or print this DRM-protected
content infringe ContentGuard's pioneering DRM patents."
The representative patents selected for the pending lawsuits are United
States Patents 6,963,859; 7,225,160; 7,269,576; 7,523,072; 7,774,280;
8,001,053; 8,370,956; 8,393,007; and 8,583,556, which disclose and claim
the DRM architecture used today in the digital distribution and
rendering of DRM-protected content, and are fundamental to how modern
DRM systems work. The developments efforts that led to these patented
inventions began with a team of inventors at Xerox PARC, including Mark
Stefik, who is widely recognized as the father of DRM.
ContentGuard is focused today on developing software and services for
Internet privacy, targeting both consumer and business solutions, and
licenses its intellectual property to companies who use its innovations
in their products and services. Spun out of Xerox PARC, ContentGuard
holds more than 300 issued patents and has hundreds of patent
applications pending worldwide. The company currently has license
agreements in place with leading technology companies, including LG,
Microsoft, Nokia, Panasonic, Sharp, Sony, Toshiba, Casio, Hitachi, Time
Warner, and Xerox. ContentGuard is owned by Pendrell Corporation
(NASDAQ: PCO) and Time Warner, and is headquartered in Plano, Texas. For
