Cisco and Apple have once again extended the deadline for Apple's legal response to Cisco's lawsuit over use of the iPhone name.

Apple now has until 21 February to file its response, the companies announced last week.

The two companies are continuing discussions in the hope of agreeing an out-of-court settlement of the dispute, Cisco said, observing that the firm is "fully committed" to reaching a "mutually beneficial resolution".

Cisco filed its suit against Apple on 10 January after Apple CEO Steve Jobs introduced the Apple iPhone at Macworld Expo, San Francisco. Cisco also owns a product called iPhone, which it acquired when it took over Infogear.

Apple has called the lawsuit "silly" and in previous statements has said it believes it will prevail in any court case regarding use of the trademark.
