BERLIN — Nokia, the world’s biggest cellphone maker, sued Apple on Thursday, claiming that Apple illegally used 10 of its patented technologies to make the iPhone, its innovative touch-screen smartphone.
Nokia said it had filed a patent infringement suit in United States District Court in Delaware. The complaint claims Apple, based in Cupertino, Calif., illegally used Nokia’s patents for wireless data, speech coding, security and encryption to make its iPhone work on GSM, UMTS and WiFi wireless networks.
