Nokia claims Apple violating patent

Nokia has slapped another complaint against rival Apple alleging patent infringements in mobile phones, portable music players, tablets and computers.

The move comes from the Finnish mobile phone maker days after the US International Trade Commission made the initial determination that Apple did not violate some other patents held by Nokia.

In a statement on Tuesday, Nokia said seven patents in the new complaint related to its "pioneering innovations" that are now being used by Apple to create key features in its products.

Apple is using these technologies in areas of multi-tasking operating systems, data synchronisation, positioning, call quality and use of bluetooth accessories, it added.

"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," Nokia's Vice-President (Intellectual Property) Paul Melin said.

Melin said that Nokia needed to build great mobile products and Apple must stop building its products "using Nokia's proprietary innovation".

Nokia-Apple battle on the patents front began in late 2009, when the mobile phone maker alleged that iPhone infringed many of its patents.

Apple has also filed patent violation complaint against Nokia.

Meanwhile, Nokia on Tuesday said it does not agree with ITC's initial observations on March 25 that there was no violation of patents.

"The company is waiting to see the full details of the ruling before deciding on the next steps in that case," the statement said.

Apart from the two complaints with the ITC, Nokia has filed cases on the same patents and others in Delaware, US.

The Finnish entity also has (patent violation) cases proceeding in Mannheim, Dusseldorf and the Federal Patent Court in Germany, the UK High Court in London and the District Court of Hague in the Netherlands.
