Nokia said Tuesday that it has filed a complaint with the U.S. International Trade Commission. In the latest volley in its patent spat with Apple, Nokia argues that its rival "infringes Nokia patents in virtually all of its mobile phones, portable music players, and computers."
The spat focuses on seven Nokia patents. Apple countered with its own suit alleging that Nokia swiped intellectual property.
In a statement, Paul Melin, head of patent licensing at Nokia, said:
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 investment in wireless standards, the ITC case filed today is about Apple's practice of building its business on Nokia's proprietary innovation.
