Nokia files patent lawsuits against HTC, RIM
By Tarmo Virki
HELSINKI (Reuters) - Wounded cellphone maker Nokia has turned on one of its former allies in the patent protection battlefield by filing lawsuits against rival smartphone maker HTC as it steps up its efforts to raise funds.
Nokia, based in Finland, filed several lawsuits in Germany covering 45 hardware and software patents, ranging from power management to data encryption technologies against HTC, Canadian rival Research In Motion and tablet-maker ViewSonic.
In the United States it filed against HTC and ViewSonic, including a complaint to the U.S. International Trade Commission (ITC) against HTC.
The moves follow Nokia's comments last month that it will seek to raise more revenues from its patent portfolio.
It is also a departure from its alliance with HTC when it had for years fought alongside the Taiwanese company in patent battles against German patent firm IPCom.
HTC said it would not comment on the legal action until its lawyers had seen the filings. "HTC has been a licensee of Nokia on wireless essential patents since 2003. We are waiting to receive a complaint," the company said in an emailed statement.
Nokia's announcement of the newest round of smartphone lawsuits comes on the same day a court in Germany ruled that Microsoft had infringed Motorola Mobility's patents.
The court ordered the world's largest software maker to remove its popular Xbox 360 gaming consoles and Windows 7 operating system software from the German market. Continued...
