Apple and AT&T, along with 20 other companies including Acer, Google, HTC, LG, Nokia, and Palm, have been sued by California-based MicroUnity Systems Engineering, which is claiming infringement of 14 separate patents. AppleInsider reports that the suit, filed last week in U.S. District Court in the Eastern District of Texas, specifically names the iPhone 3GS and third-generation models of the iPod touch, as well as competing devices including the Motorola Droid, Google Nexus One, Palm Pre, and Nokia N900. The patents specified in the suit appear to cover a wide range of mobile processor activities, relating to parallel operation, cache operation, and other general processing concepts. According to the suit, AT&T was targeted because it sells the iPhone 3GS and “services utilizing and software utilized by such products.”
