RIMs latest loss in patent war

A U.S. court tightened the noose on Research In Motion Ltd. yesterday, leaving it all but certain that the company will face a ban on its BlackBerry sales there unless it can satisfy the demands of a small patent-holding firm.
A federal judge ruled that RIM never had a valid or enforceable agreement with NTP Inc. to settle a patent infringement case it lost, despite RIM’s public assurances earlier this year that it had signed a $450-million (U.S.) deal that ended a lengthy and damaging legal battle.
