Widevine Files Patent Infringement Lawsuit Against Verimatrix


SEATTLE, WA, August 2, 2007 –Widevine today announced that it has filed a patent infringement lawsuit against Verimatrix for unspecified damages. The lawsuit comes following attempts by Widevine to openly license its intellectual property to Verimatrix. The suit was filed in U.S. District Court for the Eastern District of Texas.

Widevine has important intellectual property in the field of content protection with a robust patent portfolio of 8 issued patents and approximately 45 domestic and international patents pending.

In general, Widevine’s 7,165,175 patent describes and claims methods and systems for selectively encrypting different portions of data sent over a network. Specifically, Verimatrix’s content security solutions, such as the Verimatrix Content Authority System (VCAS), infringe on Widevine’s Apparatus, System and Method for Selectively Encrypting Different Portions of Data Sent Over A Network patent number 7,165,175. Verimatrix’s VCAS solutions—which have been sold throughout the world—practice Widevine’s selective encryption patent.

Moreover, Widevine alleges that Verimatrix has willfully infringed and continues to willfully infringe Widevine's patent rights. Widevine previously provided Verimatrix with the opportunity to openly license the selective encryption patent. Verimatrix has not responded to the open licensing opportunity.

"Widevine is a leading global creator of intellectual property innovations to protect multimedia content delivered over managed networks and the open internet. Widevine’s intellectual property is one of our core assets and represents the work product of our engineers and millions of dollars of research and development. When our intellectual property is taken, without our permission or through unauthorized licensing, we have no option but to protect it through every means available to us,” said Widevine Technologies’ General Counsel Mani Aliabadi.

Widevine will be represented by Darby and Darby, a globally recognized law firm specializing in intellectual property rights, with offices in New York, Seattle, Washington, D.C., San Jose and Frankfurt.
