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.
