US - NTP files patent suits against AT&T, Sprint and Verizon

(CNET News)
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. Way back in 2002, NTP won a jury verdict that RIM infringed on patents 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 the 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.
