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.
