Cisco Systems Inc. has given Apple Inc. until Wednesday to respond to a trademark infringement lawsuit over its use of the name "iPhone" for its new iPod-style phone.
The U.S. trademark battle was originally supposed to be resolved this Thursday, but both sides agreed to extend the deadline until next week.
Cisco's Linksys division began shipping a line of Voice over Internet Protocol — or VoIP — phones under the iPhone brand in December and has owned the trademark since 2000, when it acquired InfoGear Technology Corp.
Apple CEO Steve Jobs introduced a product he called the iPhone at the MacWorld conference in San Francisco in January. The cellular phone was lauded for its sleek design and touch-screen technology.
Both companies said they want to use the time to reach a settlement. Cisco said it would allow Apple to use the name but wants both companies' phones to be able to communicate with each other, though it did not provide information of how such interoperability would occur.
In Canada, the issue is further complicated because Comwave Telecom Inc. — and not Cisco — has owned the trademark to the name iPhone since 2004. The Toronto-based company offers its own range of voice-over-internet services under the name and even has a product called iPhone Mobile.
"Apple hasn't launched their iPhone in Canada and Cisco hasn't launched their iPhone in Canada, either," Comwave president Yuval Barzakay said last month. "So it's still yet to be determined and that's why we're taking our time and studying our moves."
Apple plans to launch its phone in June in the United States, but no Canadian release date has been announced.
