"Motorola has launched the next offensive in an increasingly confusing legal war over mobile patents. The company, through its Motorola Mobility subsidiary, has filed patent infringement complaints against Apple in both Northern Illinois and Southern Florida federal district courts. It has also asked the International Trade Commission to block Apple from importing, marketing, or selling iPhones, iPad, iPod touches, and "some Mac products."
Motorola's four complaints involve a total of 18 patents, which the company says covers everything from 3G, GPRS, and 802.11 technologies, antenna design, proximity sensing, device synchronization, and more. Motorola also says that everything from the hardware on up to iOS, MobileMe, and the App Store infringes upon its patented innovations."
