Nokia files new patent complaint against Apple

The world's leading mobile phone maker Nokia said Tuesday it was filing a fresh complaint against Apple for patent infringement in "virtually all" of Apple's devices.

The new complaint, coupled with a simultaneous lawsuit, comes days after Nokia had a previous claim rejected.

"Nokia has filed a further complaint with the United States International Trade Commission (ITC) alleging that Apple infringes additional Nokia patents in virtually all of its mobile phones, portable music players, tablets and computers," the company said in a statement.

The Finnish mobile giant claims Apple is using Nokia innovations in "key features" of its products.

Tuesday's complaint brings the number of Nokia patents in suit against Apple to 46.

"Apple has been building its business on the back of our innovations and has failed to recognise its obligations," Nokia spokesman Mark Durrant told AFP.

Last Friday a US judge with the ITC rejected Nokia's claim that Apple had violated patents in its mobile phone, portable music players and computers.

He denied Nokia's claim that Apple had violated five patents held by the Finnish company but did not provide an explanation for his ruling.

"This is not the final ruling, and the ITC full commission has in the past overturned the initial determination," said Durrant adding that the company is reviewing the decision before deciding on its next step.

The two mobile phone titans have been embroiled in a fierce legal battle over patents with Nokia lodging at least two other lawsuits against Apple and the California gadget-maker filing countersuits against the Finnish company.

Nokia has also filed similar cases in Germany, the UK and the Netherlands.

The Finnish company's sales in the competitive high-end smartphone sector have been hurt by the rise of Apple's iPhone.
