Widevine Files Second Patent in Lawsuit Against Verimatrix

SEATTLE, WA, May 20 (MARKET WIRE) --
Today Widevine has filed a motion to assert a second patent, U.S. Patent
No. 7,376,831, concerning its unique Widevine Cypher(R) technology for video
encryption against Verimatrix based on Verimatrix's sales of its infringing
Video Content Authority System (VCAS). Verimatrix is continuing to infringe and
willfully infringe Widevine's patents.

Widevine previously sued Verimatrix in the U.S. District Court for the
Eastern District of Texas for infringement of its U.S. Patent No. 7,165,175,
and that lawsuit is currently ongoing. As with its claim for infringement of
the first patent, Widevine is seeking both money damages as well as a
permanent injunction to prohibit Verimatrix from making further sales of its
infringing VCAS product line.

"Widevine has invested heavily in R&D leading to key intellectual property
innovations for securing multimedia content delivered over any network.
Widevine's
highly valuable intellectual property represents a key competitive advantage
for any video operator or internet service provider who wants to affordably and
efficiently protect copyrights, pay media revenue streams or ad-based
revenues," said Mani Aliabadi, Widevine's General Counsel. "When our
intellectual
property is taken without our permission we have no alternative but to quash
such behavior as quickly and efficiently as possible. We will not tolerate
any further abuse of our thriving patent portfolio by any company and their
investors."

Widevine has important intellectual property in the field of content
protection
with a robust patent portfolio of over 30 issued patents and numerous
domestic and international patents pending.

Widevine continues to retain Darby and Darby, a globally recognized law firm
specializing in intellectual property rights, to assert its second claim for
patent infringement against Verimatrix.
