NTP is back in lawsuit mode. The company, which forced BlackBerry maker RIM to settle the patent lawsuit between the two earlier this year, said it is suing Palm. It alleges that Palm's products, services, systems and processes violate NTP's wireless email technology. The suit seeks to bar Palm from "continuing to infringe on NTP's patents" and requests monetary damages for the alleged past infringements. Interestingly, the patent infringement centers on seven patents, five of which were part of NTP's lawsuit against RIM.
