What goes around, comes around. Apple (AAPL) on Thursday was found guilty of infringing three patents held by patent troll Mobilemedia, which is owned jointly by Nokia (NOK), Sony (SNY) and Denver-based patent licensing firm MPEG LA. The patents cover screen rotation and other features, and a United States jury determined that Apple’s iPhone is using the protected technologies unlawfully. Bloomberg was the first to report the news on its Twitter feed.
