A U.S. District Judge in Texas has ruled that patent holding firm Personal Audio cannot seek additional damages from Apple relating to a patent that the Cupertino-based company was recently found to be infringing. Personal Audio was awarded $8 million last month when Texas judge Ron Clark ruled that Apple’s iPod was infringing one of its patents covering playlist implementation. Following the win, the holding firm filed a second lawsuit alleging that additional Apple devices such as the iPhone 4 and iPad 2 also made illegal use of this patent. Judge Clark said Friday, however, that the $8 million in damages Apple paid in early July is all Personal Audio will see from Apple related to this patent. “The court finds that the jury’s selection of lump sum as the appropriate form of reasonable royalty clearly represents a damages award giving Apple a fully paid up license that covers all past and future use of the patented technology,” the Judge said in his decision. Personal Audio has not indicated how it will respond to the judge’s ruling.
