Nokia has filed claims in the US and Germany alleging that products from HTC, RIM and Viewsonic infringe a number of Nokia patents.

According to a statement, Nokia’s actions include a complaint to the US International Trade Commission (ITC) against HTC, suits against HTC and Viewsonic in the Federal District Court of Delaware, US, against HTC and RIM in the Regional Court in Dusseldorf, Germany, and against all three companies in the Regional Courts in Mannheim and Munich, Germany.
