Remember NTP? They're back.
The holding company that brought BlackBerry Nation to its knees in 2006 is once again on the advance, this time filing suit against AT&T, Verizon, Sprint and T-Mobile. The suit was filed last week in Richmond, Va., home to the last round of legal tussling between NTP and Research In Motion, maker of the BlackBerry.
Way back in 2002, NTP won a jury verdict that RIM infringed on patents held by the late Thomas Campana for a wireless e-mail system. RIM tried several times to overturn that verdict on appeal, but never prevailed, and in March 2006 the companies settled for $612.5 million. The settlement came despite that fact that the U.S. Patent and Trademark Office issued final office actions invalidating most of NTP's patents at issue in the case. NTP is appealing that decision, in a process that could stretch on for years.
