The U.S. International Trade Commission (ITC) made a preliminary ruling last week that Taiwan's HTC had infringed on two Nokia patents.
Nokia has also filed a case against the HTC One in the U.S. District Court for the Southern District of California in May. This time Nokia accused the HTC One and several other smartphones of infringing three Nokia patents. Besides litigation in the U.S., Nokia also filed lawsuits against HTC in German courts in Dusseldorf, Mannheim and Munich.
The ITC is expected to reach a full decision in late January 2014.
