Nokia has announced that it is suing Apple in Federal District Court in the Western District of Wisconsin, alleging that the iPhone and iPad with Wi-Fi + 3G infringe on five patents held by Nokia. MarketWatch reports that the patents relate to technologies for enhanced speech and data transmission, using location data in applications and innovations in antenna configurations that improve performance and save space. “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.”

The Finnish company first filed suit against Apple in October 2009, claiming that the iPhone infringes on several Nokia patents; Apple filed a countersuit claiming patent infringement in December. The lawsuits were followed by an ITC complaint from Nokia near the end of the year, alleging that Apple infringes on the Finnish company’s patents “in virtually all of its mobile phones, portable music players, and computers.”

The ITC launched an investigation into Nokia’s claims against Apple in late January; it announced a similar investigation into Apple’s claims against Nokia in February. In March, a federal judge in Delaware signed an order halting litigation between Nokia and Apple pending resolution of the companies’ respective claims with the U.S. International Trade Commission (ITC); it is unclear whether this prior order will have any bearing on this newest lawsuit.
