Just as the dust had finally settled on the NTP lawsuit, Research in Motion has been hit with more patent-infringement allegations--this time, by wireless e-mail provider Visto. The new suit comes after a federal jury in the U.S. District Court for the Eastern District of Texas found that its rival, Seven, infringed on three different Visto patents and awarded the company $3.6 million in damages. The victory gave Visto the green light to go after RIM, alleging that the BlackBerry maker infringes on four of its patents. Brian Bogosian, CEO of Visto, said in a statement, "Based on Visto's sweeping victory in court against Seven Networks on Friday, RIM must understand that there is no place in the mobile e-mail space for this sort of behavior." RIM rebutted, "Based on prior art and actual products in market, RIM believes Visto's patents are invalid," and added that it is "fully prepared and equipped to deal with the matter." Oh boy, here we go again. For all the sordid details, check out Anne Broache's story on News.com.
