USPTO dismisses 20 patent claims by Apple as invalid

A post on Foss Patents blog has revealed that the United States Patent and Trademark Office (USPTO) has issued a first Office action, asserting that a crucial Apple multitouch patent is invalid. In fact, the decision comes for the second time within two months. It was in late October that a first Office action asserted that all the 20 claims of Apple's rubber-banding patent are invalid.
