Digital Trends – U.S. Circuit Court Judge Richard Posner has significantly narrowed the high-profile patent litigation between Apple and Motorola over the technology used in their iOS and Android-powered mobile devices, reducing the number of claims in the case that could go to trial from eight to five. Posner ruled that one of Appleâs patents in the case is invalid, and that Apple was not guilty of infringing on Motorola patents for authenticating telecommunications users and encrypting communications. However, the five remaining issues are eligible to go to trial. Posner has given the companies until January 23 to decide which of the remaining five issues they want tried; the jury trail has been scheduled to start June 11.
