Two months after launching a patent infringement suit against Apple regarding the iPhone, Finnish wireless handset maker Nokia filed a complaint with the U.S. International Trade Commission (ITC) that accuses Apple of infringing Nokia patents in “virtually all of its mobile phones, portable music players, and computers.” Filed on Tuesday, the ITC complaint covers the Apple iPod as well as Apple’s line of iMac computer products. The Nokia patents that Apple is charged with violating relate to user interface technologies, camera features, antennas, and power management. Nokia’s pending patent suit regarding the iPhone, meanwhile, accuses Apple of infringing ten Nokia patents that, among other things, relate to Wi-Fi access. Apple, which has denied all charges, fired back earlier this month with the filing of a countersuit that accuses Nokia of appropriating certain iPhone technologies in smart phones produced by the Finnish company. Declaring that “Nokia has been the leading developer of many key technologies in small electronic devices,” a Nokia official proclaimed: “this action is about protecting the results of such pioneering development.”
