Nokia Corp. (NYSE: NOK) has filed a second complaint with the U.S. International Trade Commission alleging that Apple Inc. (NASDAQ: AAPL) infringes its patents in virtually all of its mobile phones, portable music players, tablets and computers.

The Finnish cellphone giant, which is already engaged in a legal battle over smartphone technology with Apple, said the latest filing means it now has 46 Nokia patents in suit against Apple, many filed more than 10 years before Apple made its first iPhone.

The new complaint involves seven patents that Nokia said Apple is using to create key features in its products in the areas of multi-tasking operating systems, data synchronization, positioning, call quality and the use of Bluetooth accessories.

Apple won a ruling from ITC on March 25 that it wasn’t violating Nokia’s rights on five patents. Nokia said it 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.

During the last two decades, Nokia has invested about 43 billion euros in research and development and built one of the wireless industry's strongest and broadest IPR portfolios, with around 11,000 patent families.
