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 has just lost one of its magic patent bullets thanks to a non-final Office action by the USPTO. Patent No, 7,469,381 (used against Samsung in California) has been declared invalid after evidence supporting prior art (as well as being obvious) was brought about during a reexamination request.

This news is not only great for Samsung, but many other manufacturers who are currently caught up in Apple’s legal charades.
