Finnish mobile phone maker Nokia has filed a second complaint against Apple with the United States International Trade Commission (ITC), alleging that the company is infringing even more Nokia patents with its mobile phones and portable music players, as well as with its tablets and computers.

According to Nokia's new complaint, the Cupertino-based company is infringing a number of no less than seven additional Nokia patents.

The company also notes that these patents relate to pioneering innovations from Nokia, which are being used now for the creation of key features in its products in areas like multi-tasking operating systems, data synchronization, or positioning, as well as in call quality and the use of Bluetooth accessories.

The new complaint was filed following the initial determination in Nokia's earlier ITC filing, which was announced on Friday, March 25th.

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,” the company announced.

On top of these two ITC complaints, Nokia also announced that it has filed cases on the same patents and others with the district court of Delaware, US.

The company also has 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 these should 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.”

Nokia made investments of over EUR 43 billion in research and development during the past few decades, and holds one of the strongest and broadest IPR portfolios in the the wireless industry, including over 10,000 patent families.
