The United States Patent Office has invalidated all 20 claims of Patent No, 7,469, 381, the patent covering the rubber-banding user interface feature of Apple's iOS mobile operating system. The news emerged today, casting some doubt on whether some aspects of Apple's $1.05 billion verdict against Samsung will stand. The invalidation is tentative in nature, meaning that the patent will go through a lengthy process in order to determine whether it will be fully invalidated.
