Submission + - Cisco Lost Rights To iPhone Trademark
Umbral Blot writes: "
The Cisco iPhone trademark was registered 11/16/1999 (Reg. No. 2293011). In order to keep a trademark registration active, you have to file a Declaration of Use on or before the sixth anniversary of the registration date, in which you state, under penalty of perjury, that you have been using the trademark continuously during that period. The sixth anniversary would have been 11/16/2005. Cisco did not file the Declaration of Use by 11/16/2005, which if they had been using the trademark would seemingly have been easy to do.
Cisco did file a Declaration of Use during the six month grace period, but it appears they may have done so improperly, invalidating their claim."
