Nokia has filed a second complaint (it recently lost the first) with the United States International Trade Commission alleging that Apple infringes Nokia patents in virtually all of its mobile phones, portable music players, tablets and computers.
There are seven Nokia patents in the new complaint which the company says are being used by Apple to create key features in its products.
These feature fall mainly into the areas of multi-tasking operating systems, data synchronisation, 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," 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."
Nokia says that over the last two decades, it has invested approximately EUR 43 billion in research and development.
