Research in Motion Ltd. (RIM) announced that the Federal Patent Court in Munich, Germany have ruled in its favor in the patent infringement case with the patent-holder InPro. InPro, which is based in Luxembourg, claimed that several of the manufacturer's Blackberry devices had breached the patent. The court, however, found all of InPro patent claims invalid. As the court's decision is based on the European Patent (EP) application, it will be valid throughout the European Union. The patent-holding company still has the right to appeal. The German ruling comes at the time when RIM leads a long-running patent battle with NTP in the United States. As phonearena.com informed last week, the U.S. district court had set February 24, 2006 as a hearing date to consider a possible shutdown of the Blackberry services in the States.
