Nokia has accused Apple of infringing Nokia patents in many of its products, including the iPhone, iPod and some...
A case filed with the US International Trade Commission (ITC) claims patented Nokia innovations are being used by Apple to develop key features in its products, according to reports.
The alleged infringements relate to user interfaces and camera, antenna and power management technologies.
Nokia and Apple are already involved in a legal battle that started in October when Nokia filed a suit against Apple in the US District Court for the District of Delaware.
In that case, Nokia claims infringement of 10 patents dealing with core aspects of the three key wireless standards used in the iPhone.
Nokia maintains that failing to pay royalties has given Apple a competitive advantage because it can afford to charge less for its iPhone, according to the complaint filed in Delaware.
Apple has since countersued, alleging that Nokia infringed 13 Apple patents.
