Apple’s “pinch to zoom” patent, which features prominently in a patent dispute against Samsung, has been dismissed by the U.S. Patent and Trademark Office. According to documents filed by Samsung in a U.S. federal court, all 21 claims of the patent have been rejected in a “final office action.”

Google has countersued British Telecom, a multinational telecommunications company based in the United Kingdom, with a new patent infringement lawsuit filed in the U.S. and the U.K. BT first took legal action against Google back in 2011, but Google has called its complaint “meritless,” and accuses the company of “arming patent trolls.”
