Yahoo Screen may be defunct, but that isn't stopping OpenTV Inc., a subsidiary of European media company Kudelski Group, from citing it in a counter lawsuit alleging that Yahoo is infringing on 10 of its patents.
It's the latest salvo in an ongoing patent battle between Yahoo and OpenTV; in January, Yahoo filed a suit to attempt to partially invalidate one patent and to prove it did not infringe on six other patents owned by OpenTV.
If OpenTV and Kudelski sound familiar, it's because the subsidiary has battled other online video providers, like Netflix, in the past over patents OpenTV owns. FierceCable has more details here.
