Blackberry addicts are facing their darkest fears as Blackberry manufacturers, Research in Motion (RIM) try to overturn a court decision they lost five years ago to NTP who hold a patent which NTP say (and a court upheld) had been infringed in the Blackberry hand held mobile/computer device. RIM received good news last week when the US Patent Office ruled that the patent owned by NTP was not relevant to RIM’s invention and should be cancelled. But simultaneously on the 24 th February the US District Court in Richmond, Virginia, will decide whether NTP’s 2003 injunction against RIM should stand. RIM are contesting the injunction not least because they believe that in the event of a decision against RIM, NTOP could be fully compensated by financial recompense. A tentative £235 million settlement between the parties failed and the US Supreme Court has refused to intervene, leaving the decision to the District Court (Judge James Spencer).
