Apple Inc. filed a new patent- infringement complaint against Nokia Oyj, seeking to block U.S. imports of mobile phones and increasing the legal battle between the two over smartphone technology.
Notice of the complaint was posted yesterday on the Web site of the U.S. International Trade Commission in Washington. Nokia, the world’s largest maker of mobile phones, filed its own complaint last month at the ITC, seeking to ban imports of Apple’s iPhone, iPod and MacBook products.
The patent fights are part of a larger battle over the smartphone market, the industry’s fastest-growing sector. Nokia’s share of the market fell to 39.3 percent in the third quarter from 42.3 percent a year earlier, while Cupertino, California-based Apple and Research In Motion Ltd., the Waterloo, Ontario-based maker of the BlackBerry, gained, according to research firm Gartner Inc. in Stamford, Connecticut.
