Nokia has announced that it's moving to protect its intellectual property by launching various claims of patent infringement against HTC, RIM and Viewsonic.
The suits have been filed in both the US and Germany, although litigation is an action the Finnish company would prefer not to take, Nokia assures us.
Louise Pentland, chief legal officer, commented: "Nokia is a leader in many technologies needed for great mobile products. We have already licensed our standards essential patents 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."
The claims include suits against HTC and Viewsonic in the Federal District Court of Delaware, and a complaint to the US International Trade Commission against HTC.
Over in Germany, the suits include action against HTC and RIM in the Regional Court in Dusseldorf, and a volley fired at all three firms in the Regional Courts in Mannheim and Munich. Nokia would appear not to be mucking around, and a total of 45 patents are cited across all these cases.
Areas which Nokia argues are being infringed include hardware capabilities such as power management, multimode radios, dual function antennas, and software features including app stores, dynamic menus, data encryption and retrieval of emails on a mobile.
Pentland noted: "Many of these inventions are fundamental to Nokia products. We'd rather that other companies respect our intellectual property and compete using their own innovations, but as these actions show, we will not tolerate the unauthorized use of our inventions."
