Finnish mobile phone maker Nokia has filed another lawsuit against rival Apple with the US International Trade Commission.
The lawsuit comes just days after the ITC ruled against Nokia in its long-running patent battle with the iPhone maker, deciding that Apple had not violated five Nokia patents.
The latest patent infringement complaint filed by Nokia accuses Apple of violating seven Nokia patents in most of its products including phones, tablets, computers and media players.
The seven Nokia patents are related to call quality, Bluetooth accessories, multi-tasking capabilities in operating systems and data synchronisation.
Nokia first started the patent war with Apple by filing a complaint with the ITC accusing Apple off infringing five of its patents. Apple had replied with a patent infringement lawsuit of its own. An ITC judge recently ruled in favour of Apple, dismissing five of the patents cited by Nokia.
Paul Melin, vice president of intellectual property at Nokia, said in a statement, “Our latest ITC filing means we now have 46 Nokia patents in suit against Apple, many filed more than 10 years before Apple made its first iPhone.”
“Nokia is a leading innovator in technologies needed to build great mobile products and Apple must stop building its products using Nokia's proprietary innovation,” he added.
