The US Patent and Trademark Office has issued a final rejection of one of the five patents at issue in NTP's long-running case against BlackBerry maker Research In Motion.
If Research In Motion survives its patent dispute with NTP in the United States it will most likely have to repeat the saga with Visto, which claims to have an equally strong case against the Blackberry maker.
BlackBerry maker Research In Motion has repeatedly mischaracterised the validity of disputed NTP-held patents and wielded political influence to advance its position, the patent-holding company charged on Thursday.
Research In Motion has come up with a 'workaround' to skirt patents at the centre of its legal battle with NTP, and the technology could be used with all existing BlackBerry e-mail devices, the firm's co-chief executive said on Thursday.
A workaround by Research In Motion, designed to avoid infringing patents held by intellectual property company NTP, is simply a negotiating tactic to help the BlackBerry maker settle out of court, according to analyst group Gartner.
