Blackberry Maker Faces More Patent Litigation
“Research In Motion Ltd., which paid $612.5 million to resolve a patent lawsuit in March over its Blackberry wireless e-mail device, filed a complaint challenging another company’s infringement claims.
“Research In Motion asked a federal court in Dallas to rule that the BlackBerry doesn’t infringe patents owned by Visto Corp., a Redwood Shores, California-based company that provides e-mail software to cell phone companies. The lawsuit was filed May 1, the first business day after Visto filed its own suit against Research In Motion in federal court in Marshall, Texas.
