HELSINKI (Reuters) - Nokia <NOK1V.HE> said on Tuesday it had filed another complaint with the U.S. trade panel (ITC) alleging that rival Apple <AAPL.O> infringes Nokia patents in virtually all of its products.
Last Friday Apple won a round in its patent fight with Nokia as the United States International Trade Commission judge ruled that the U.S. company did not violate any of five Nokia patents.

On Tuesday Nokia filed a new case relating to seven patents in areas of multi-tasking operating systems, data synchronization, positioning, call quality and the use of Bluetooth accessories.
"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," Paul Melin, Nokia's vice president, intellectual property, said in a statement.
Legal disputes between the two technology groups are also being heard in courts in the United States, Britain, Germany and the Netherlands.
