We've previously reported a few weeks ago that Cisco Systems gave the Cupertino-based Apple up to February 15 to respond to the Lawsuit that they've filed over the iPhone trademark. Well, here's an update to that situation, and from the looks of things, Cisco is one patient bunch.

Jennifer LeClaire of NewsFactor Network reports that Cisco is offering Apple yet another extension on its deadline to respond to a trademark lawsuit over the iPhone name.

The trouble between the two companies began when, on January 10, Cisco representatives filed a lawsuit at the District Court of Northern California "seeking to prevent Apple from infringing upon and deliberately copying and using Cisco's registered iPhone trademark."

Cisco apparently obtained the iPhone trademark in 2000 after completing the acquisition of InfoGear, which previously owned the mark and sold iPhone products for several years. That was around a day or after Steve Jobs introduced Apple's iPhone to the world.

Perhaps Cisco felt that this was the appropriate way to let Apple know that any negotiations they had before weren't settled. Just how long is Cisco willing to wait? How is Apple handling this? We'll update you as soon as more information is made available.
