The United States Patent and Trademark Office (USPTO) has rejected claims by Apple that Samsung Electronics infringed on its "pinch-to-zoom" patent – one of the decisive claims in the ongoing litigations between the two tech giants. The patent, No. 7,844,915, was first filed back in November 2010 and described, "an environment with user interface software interacting with a software application". The patent was preliminarily rejected back in December 2012 before the final verdict was delivered today
