Nokia to sue over patents

Saying it will protect its innovations and intellectual property, Nokia is commencing patent litigation in the U.S. and Germany against U.S.-based Viewsonic, HTC of Taiwan, and Research in Motion of Canada.

The company says it already licenses the 45 patents in question to more than 40 companies. “Though we’d prefer to avoid litigation, Nokia had to file these actions to end the unauthorized use of our proprietary innovations and technologies, which have not been widely licensed.”

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.

Nokia says the patents cover dual function antennas, power management and multimode radios, application stores, multitasking, navigation, conversational message display, dynamic menus, data encryption, and retrieval of email attachments on a mobile device.

Also: Nokia posted a $1.2 billion net loss for first quarter of 2012.
