The Kudelski Group said OpenTV, its video apps and middleware unit, has filed patent infringement counterclaims against Yahoo that spans ten patents.
The suit, filed in the United States District Court for the Northern District of California, alleges that Yahoo is infringing on patents that are used or have previously been used to power products and services such as Yahoo Smart TV, Yahoo Connected TV, Yahoo TV, Yahoo interactive video advertisements, Yahoo fantasy gaming and Yahoo Screen, which Yahoo shuttered earlier this year.
Yahoo, which is in the process of shedding non-strategic assets and recently extended the bidding process of its Internet assets to April 18, has already announced that it is exiting some legacy product areas, including games and smart TVs.
OpenTV noted that its filing also responds to a complaint for declaratory judgment filed by Yahoo on January 21, 2016. In that move, made in a California federal court, Yahoo claimed that it did not infringe seven patents held by OpenTV, according to Law360.
Kudelski took control of OpenTV in late 2009, and, in 2014, sold OpenTV’s advanced advertising business to Imagine Communications.
