Widevine Files Virtual Smart Card Patent Infringement Lawsuit Against Verimatrix

Patent Covers Key Requirements to Manage Encryption for Any DCAS/DRM System

SEATTLE, WA--(Marketwire - July 8, 2008) - Widevine today announced that it has filed a third claim for patent infringement against Verimatrix. The lawsuit accuses Verimatrix of infringing Widevine's 7,299,292 patent through Verimatrix's sales and distribution of its ViewRight client application. The lawsuit seeks damages and an injunction to stop sales of the infringing products.

This patent describes a process and streaming server for encrypting a data stream to a virtual smart card client system. The patent generally covers software-based "virtual smart cards" on a set top box, personal video recorder (PVR), PC or mobile device that manage the flow of data over a network. The suit was filed in U.S. District Court for the Western District of Washington in Seattle.

Widevine had previously filed another lawsuit against Verimatrix that accuses the Verimatrix Video Content Authority System (VCAS) of infringing Widevine's key patent relating to real-time encryption. Widevine later asserted a second claim for infringement of another patent in that suit. That suit is continuing. Widevine has important intellectual property in the field of content protection with a robust patent portfolio of more than 35 issued patents and approximately 90 domestic and international patents pending.

"With this third claim for infringement in the new suit, we are validating our customer's and investor's trust and investment in the strength of Widevine's intellectual property portfolio while sending a clear message to direct and indirect infringers of our patents that they must respect our intellectual property," said Mani Aliabadi, Widevine's General Counsel.

This is the third patent infringement claim filed by Widevine against Verimatrix. In August of 2007 Widevine filed its initial patent infringement lawsuit against Verimatrix for its 7,165,175 patent. In May of 2008 Widevine added its 7,376,831 patent to the on-going 7,165,175 litigation. The existing patent litigation continues to progress through the court appointed milestones and the following is an update on recent litigation activity.

As expected, the PTO recently granted an inter partes reexamination of Widevine's 7,165,175 patent for selective encryption patent, one of the two patents in that first lawsuit. While over 90% of such reexamination requests are granted, fewer than 15% typically result in all claims being cancelled. The PTO only granted reexamination concerning narrow issues in the petition, and stated that most of Verimatrix's arguments were completely without merit. Verimatrix has not requested reexamination of Widevine's other 7,376,831 patent in that suit.

"Widevine is confident that the selective encryption claims will be re-confirmed by the Patent Office. The reexamination is based on prior art that the Patent Office has already considered in connection with patent no. 7,376,831 and found not to be a problem. We welcome this opportunity for the PTO to reconfirm the value and strength of Widevine's selective encryption patent and to eliminate any future questions of validity," said Mr. Aliabadi.
