Summary Judgment Granted in Favor of L&P Client

The United States District Court for the Eastern District of Texas today granted summary judgment in favor of Laurence & Phillips IP Law (L&P) client KAIFI LLC and against T-Mobile.  T-Mobile brought the case to get out from under a settlement agreement T-Mobile entered into with KAIFI to resolve an infringement case concerning Kaifi’s U.S. Patent No. 6,922,728, which covers so-called “WiFi calling.”  L&P had successfully represented KAIFI in two ex partereexaminations of the ’728 Patent, which was fully confirmed by the United States Patent and Trademark Office’s (PTO’s) Central Reexamination Unit (CRU) during the reexaminations.  In this latest suit, T-Mobile accused L&P partner Matt Phillips of inequitable conduct during the reexaminations, but the court’s summary-judgment ruling sided with KAIFI.  Phillips remarked, “There was absolutely no merit in T-Mobile’s inequitable-conduct assertions, and today’s ruling appropriately puts those unpleasant and unfounded accusation behind us.”
