OpenTV, Nagravision Sue Apple

OpenTV and Nagravision, units of the Kudelski Group, have filed a lawsuit against Apple, alleging that the maker of the iPad and Apple TV is infringing on five U.S. patents.

The suit, filed Wednesday with the U.S. District Court of the Northern District of California, claims that several Apple products are infringing, including its iOS-powered iPhones, iPads and iPods, the Apple TV, the Apple App Store and iTunes, iADs service, Safari browser, and OS X-based computers.

The five patents asserted by the Nagravision/OpenTV-led suit are:

-No: 5,689,799: “Method and apparatus for routing confidential information;”  

-No. 5,884,033: “Internet filtering system for filtering data transferred over the internet utilizing immediate and deferred filtering actions;”

-No. 5,566,287: “Method for asynchronously maintaining an image on a display device;”

-No. 6,985,586: “Distributed information storage system;” and,

-No. 7,900,229: “Convergence of interactive television wireless technologies.”

Nagravision, a maker of security and digital rights management products and technologies, and OpenTV, a unit that specializes in video apps, advanced advertising systems and set-top middleware, are seeking a permanent injunction, attorneys fees, and unspecified financial damages that are “in no event less than a reasonable royalty.”

Apple was not immediately available for  comment.

OpenTV, acquired in full by Kudelski in 2010, filed a patent-infringement lawsuit against Netflix in 2012, alleging that Netflix infringes seven U.S. patents owned by OpenTV that cover Internet video delivery.
