Apple is suing unnamed individuals who leaked details about an unannounced product by posting detailed information on the Web. Apple’s complaint, which was filed with the Santa Clara County California Superior Court on Dec. 13, alleges that “an unidentified individual, acting alone or in concert with others, has recently misappropriated and disseminated through Web sites confidential information about an unreleased Apple product.” Apple said it did not know the “true names or capacities, whether individual, associate, corporate or otherwise,” of the defendants. Once they have been discovered, the company said it would amend the complaint. “To succeed, Apple must develop innovative products and bring those products to market in advance of its competitors,” the company said. “If Apple competitors were aware of Apple’s future production information, those competitors could benefit economically from that knowledge by directing their product development or marketing to frustrate Apple’s plans.”
