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.”

Apple’s quest for litigation has resulted in a few wins and a few loses. However, it would seem the big picture isn’t looking so good for Apple. The very patents Apple has been attempting to assert in its litigation crusade are now coming under high scrutiny and slowly being invalidated.
