The world's largest mobile phone-maker Nokia today said it filed a complaint with the US International Trade Commission (ITC) alleging Apple of infringing Nokia patents in virtually all of its mobile phones, portable music players and computers.
The seven Nokia patents in this complaint relate to Nokia's pioneering innovations that are now being used by Apple to create key features, the company said in a statement issued in Finland.
These innovations are used by Apple in its products in the area of user interface, as well as camera, antenna and power management technologies, the statement added.
These patented technologies are important to Nokia's success as they allow better user experience, lower manufacturing costs, smaller size and longer battery life for Nokia products.
"Nokia has been the leading developer of many key technologies in small electronic devices" said Nokia general manager for patent licensing Paul Melin.
"This action is about protecting the results of such pioneering development. While our litigation in Delaware is about Apple's attempt to free-ride on the back of Nokia's investment in wireless standards, the ITC case filed today is about Apple's practice of building its business on our proprietary innovation."
