Nokia said in a statement today that it has filed a complaint against Apple with the Federal District Court in the Western District of Wisconsin, alleging that Apple iPhone and iPad 3G products infringe five important Nokia patents.

The patents in question relate to technologies for enhanced speech and data transmission, using positioning data in applications and innovations in antenna configurations that improve performance and save space, allowing smaller and more compact devices. These patented innovations are important to Nokia’s success as they allow improved product performance and design.

The patents in this case are different to those included in Nokia’s previous suits against Apple, the first of which was filed in October of last year.

“Nokia has been the leading developer of many key technologies in mobile devices” said Paul Melin, General Manager, Patent Licensing at Nokia. “We have taken this step to protect the results of our pioneering development and to put an end to continued unlawful use of Nokia’s innovation.”
