One of the key patents Apple used in the billion dollar patent battle against Samsung is at risk after a re-examination by the U.S. Patent and Trademark Office. U.S. Patent No. 7,844,915 and all 21 claims associated with it were rejected by the Patent Office, following a re-examination.
Known as the “pinch to zoom” patent, it was one of the key patents Apple used against Samsung which secured their billion dollar win. It covers the technology that distinguishes between single finger scrolling versus multi-point touch at once for a pinch-to-zoom action. Now that the patent is under re-examination, Apple could be on thin ice and a retrial might be a possibility. Samsung has pointed out in a filing to U.S. District Court Judge Lucy Koh who noted that it was “relevant”. Earlier this week, Samsung’s motion for a retrial was shot down as well as Apple’s attempt at an injunction against several Samsung devices that infringed on the ‘915 patent.
During the re-examination process, the Patent Office found that all 21 claims were invalid based on claims from other patents.
