The U.S. patent office rules an Apple (AAPL) patent used in its pinch-to-zoom implementation shouldn't have been granted, boosting Samsung (SSNLF.PK) in its attempt to overturn a $1.05B U.S. jury verdict against it in its global IP war with Apple. The patent was one of six that Samsung was ruled to have breached in the companies' summer trial and is the second of those six to have been preliminarily struck down.
