Six weeks after Apple’s much-publicized introduction of the iPhone, Cisco Systems settled a legal dispute Wednesday with Apple over Apple’s usage of the iPhone trademark. At the MacWorld conference in January, Apple unveiled the multimedia iPhone, which combines the features of a cellular phone with those of the company’s existing iPod products. Apple plans to begin marketing the iPhone in June at a base retail price of $499. The day after Apple’s announcement, Cisco filed suit in a San Francisco federal court, claiming that Apple’s use of the iPhone name infringed upon trademarks held by Cisco since 2000. Since last spring, Cisco has been marketing a line of Linksys phones under the iPhone name that enable users to make calls over the Internet using voice-over-Internet-protocol technology. Although Apple argued that its iPhone would operate over a different network and would therefore not compete with the Cisco iPhone, Cisco maintained that, in the current era of convergence, the two companies’ products could eventually compete against each other, thereby leading to “confusion, mistakes and deception among consumers.” The settlement, which ends litigation between the companies, permits Apple to use the iPhone name. Although financial terms were not disclosed, the companies further agreed to “explore opportunities for interoperability in the areas of security, and consumer and enterprise communications.”
