OpenTV files patent counter-claim against Yahoo

Kudelski-owned TV technology provider OpenTV has filed a patent infringement counter-suit against Yahoo in the US in the District Court for the Northern District of California.

The counterclaims allege that Yahoo infringes 10 US patents owned by OpenTV and identify several infringing products and services, including Yahoo Smart TV, Yahoo Connected TV, Yahoo TV, Yahoo interactive video advertisements, Yahoo fantasy gaming and Yahoo Screen.

OpenTV’s filing also responds to a complaint for declaratory judgment filed by Yahoo on January 21. In that filing, Yahoo, following receipt of a letter sent to it by OpenTV, said that it did not infringe seven OpenTV patents. In its suit, Yahoo also attempted to partially invalidate one of the patents.

The patents in question relate to interactive TV, security and sports trivia quizzes.
