Cisco might have lost iPhone trademark in '06
"Apparently Cisco has more "iPhone" trouble in store for it than just that prior art dispute we mentioned yesterday. In order to keep a trademark alive, you have to file a "Declaration of Use" with the US Patent and Trademark office every six years or forfeit the trademark. On 11/16/2005 Cisco missed that deadline, but was granted a six month grace period, which it just barely squeezed through. Unfortunately for Cisco, a "Declaration of Use" requires demonstration of active use, under penalty of perjury."
