A non-practicing entity called MobileMedia Ideas LLC won a patent lawsuit against Apple today, with a Delaware federal jury finding that Apple should pay $3 million for infringing MobileMedia’s patent RE39,231, which relates to ring-silencing features on mobile phones.

MobileMedia is an unusual example of the kind of pure patent-licensing entity often derided as a “patent troll.” It is majority-owned by MPEG-LA, a patent pool that licenses common digital video technologies like H-264, MPEG-2 and MPEG-4. Minority stakes in MobileMedia are owned by Sony and Nokia, which both contributed the patents owned by the company. MobileMedia also has the same CEO as MPEG-LA, Larry Horn.

The report of the verdict comes from legal newswire Law360. The verdict form wasn’t immediately available from PACER, the federal courts database.
