The trademark registrant no longer uses the registered trademark because of changing the name, mark or other reasons, and voluntarily renounces the exclusive right of the trademark to the trademark registration authority; In this case, the original trademark will be cancelled. Then the cancellation of a trademark should also be submitted to the Trademark Office for review. How long will it take to review the cancellation of a trademark? It will take about 3 months at the earliest to cancel the trademark after submitting the relevant application documents, depending on the time of the trademark office. Now it is basically unclear about the specific time! When we need to inquire about the progress of the cancellation of the trademark after we submit it, the Trademark Office receives the cancellation application, cancels the registered file of the trademark, and publishes the cancellation announcement of the trademark on the 28th of each quarter.
