Apple has lost a German court case over video streaming patents.

The Dusseldorf District Court on Tuesday ruled that iDevices sold in Germany may not use streaming software that infringes on OpenTV’s licenses, Reuters reports(Opens in a new window).

Kudelski Group’s OpenTV software platform sued Cupertino in Germany two years ago, claiming that various products violate its copyrights. The suit specifically targets iOS and OS X devices, Apple TV, iTunes, and the App Store.

“The claim is predominantly valid and well-founded,” the Dusseldorf court said in its Tuesday ruling, according to Reuters.

Neither Apple nor Kudelski immediately responded to PCMag’s request for comment.

Switzerland-based Kudelski has developed and acquired a host of movie and digital TV technologies over the decades—including OpenTV, which it purchased in 2010.

The program—”an early player in the digital television industry,” AppleInsider wrote last year(Opens in a new window)—now focuses on video-on-demand, personal video recording, and enhanced TV applications.
