The presiding judge in the case, U.S. District Judge William Conley, recently ruled that Apple could face up to $862.4 million in damages. The new suit claims that the iPhone-maker has once again violated the same patent for its A9 and A9X processors, which are found on the iPhone 6s and the upcoming iPad Pro, respectively.
In 2009, WARF filed a similar lawsuit against Intel for violation of the same patent, which was settled out of court.
