An Apple v. Samsung court filing on Wednesday reveals that the U.S. Patent and Trademark Office invalidated Apple's "pinch-to-zoom" patent



From Apple Insider:

Brought to the court's attention by Samsung in an effort to bolster its motion for a new trial, the USPTO decision invalidated all 20 claims of Apple's U.S. Patent No. 7,844,915 after reexamining the property. The Korean company also said in the court filing that the finding was relevant to block Apple's motion for an injunction against a number of Samsung products.

Presiding Judge Lucy Koh on Monday denied both Samsung's motion for a retrial and Apple's request for an injunction, though the decisions can be appealed at a later date.
