Apple's "pinch-to-zoom" patent rejected by U.S., WSJ reports

In a preliminary ruling, the U.S. Patent and Trademark Office rejected Apple's (AAPL)"pinch-to-zoom" patent, which the company used as a cornerstone of its case against Samsung Electronics (SSNLF), reports the Wall Street Journal. The patent office said that for Apple's claims to be valid, they must be considered patentable despite any "prior art patent and printed publication cited." In its report, the agency said they did not.
