Emboldened by a recent victory in a patent lawsuit, wireless e-mail software provider Visto Corp. said Monday it is suing Research in Motion Ltd., the maker of BlackBerry mobile devices, over similar claims. It's the latest twist in the tangle of legal battles over wireless e-mail, the most highly publicized of which ended in March with RIM agreeing to pay NTP Inc. $612.5 million to settle a four-year dispute. Visto, a privately held Redwood Shores-based company, provides e-mail software to cell-phone companies, including Sprint Nextel Corp. and Vodafone Group. It filed a lawsuit against RIM in federal court for the Eastern District of Texas on Friday, the same day a jury there handed it a legal victory in its patent infringement case against rival Seven Networks Inc. The jury found that Redwood City-based Seven had infringed on three of Visto's mobile e-mail patents and awarded Visto about $3.6 million in damages.
