Research In Motion Comments on Patent Complaint by Visto


Waterloo, Ontario - Research In Motion Limited (RIM) (Nasdaq: RIMM; TSX: RIM) today learned that a complaint alleging patent infringement has been filed in the U.S. Eastern District Court of Texas by Visto Corporation against RIM. Visto is alleging infringement of four patents (#6,023,708, #6,085,192, #6,151,606 and #6,708,221) and seeking an injunction and monetary damages.

Visto has already filed patent complaints against several companies in the industry, including Microsoft, Good Technology, Smartner and Sproqit. Visto filed its complaint against RIM immediately following a jury verdict in its litigation against Seven Networks.

RIM has been monitoring Visto’s litigation against other companies in the industry and, based on prior art and actual products in market, RIM believes Visto’s patents are invalid. Further, Visto’s patent claims as directed against Seven Networks refer to a different type of system than RIM’s technology. RIM believes it does not infringe Visto’s patents and will file its legal response in due course. In addition to challenging validity and infringement, RIM will now also consider asserting its own patents against Visto.

RIM is fully prepared and equipped to deal with the matter and will continue to disclose material information as it becomes available. RIM does not expect its customers to be impacted by Visto’s complaint and, given the status of Visto’s current litigation with other companies, it is unlikely that any material court proceedings in this litigation could begin prior to the middle of calendar 2007.
