Nokia said on Tuesday it had filed a new complaint with the U.S. trade panel (ITC) alleging that rival Apple infringed Nokia patents in virtually all of its products. The seven Nokia patents in the new complaint relate to Nokia's 'innovations' that are now being used by Apple to create key features in its products in the areas of multi-tasking operating systems, data synchronization, positioning, call quality and the use of Bluetooth accessories, the company said.

This second ITC complaint follows the initial determination in Nokia's earlier ITC filing, announced by the ITC on Friday, March 25. Nokia does not agree with the ITC's initial determination that there was no violation of Section 337 in that complaint and is waiting to see the full details of the ruling before deciding on the next steps in that case.

In addition to the two ITC complaints, Nokia has filed cases on the same patents and others in Delaware, US and has further cases proceeding in Mannheim, Dusseldorf and the Federal Patent Court in Germany, the UK High Court in London and the District Court of the Hague in the Netherlands, some of which will come to trial in the next few months.

"Our latest ITC filing means we now have 46 Nokia patents in suit against Apple, many filed more than 10 years before Apple made its first iPhone," said Paul Melin, Vice President, Intellectual Property at Nokia. "Nokia is a leading innovator in technologies needed to build great mobile products and Apple must stop building its products using Nokia's proprietary innovation."
