What is a cancellation of a trademark?
Cancellation of a trademark means that the trademark passed through all the phases, was registered then was cancelled from the registry, either because:
1) A third party filed a cancellation action; or
2) The trademark was not properly renewed or updated; or
3) The trademark was not properly used (not applicable in all jurisdictions); or
4) An owner of a trademark requests to cancel it from the registry.
Trademark cancellation procedures are different depending on jurisdiction and may be administrative proceedings or legal ones depending on the jurisdiction.
