Corresponding to different invalidation situations of trademark rights, the procedures for invalidation of trademark rights are also different.

(1) There are two kinds of invalidation procedures for registered trademarks with obvious defects:

1. The Trademark Office may revoke the registered trademark on its own initiative;

2. Other units or individuals may request the Trademark Review and Adjudication Board to make a ruling to cancel the registered trademark.

(2) For an improperly registered trademark, the trademark owner or interested party may request the Trademark Review and Adjudication Board to cancel the registered trademark within five years from the date of trademark registration. For malicious registration, the owner of a well-known trademark is not subject to a five-year time limit.

(3) In the event of a dispute over a registered trademark, the earlier registered trademark owner may apply to the Trademark Review and Adjudication Board for a ruling to cancel the later registered trademark within five years from the date when the disputed trademark is approved for registration.

for a trademark that has been challenged and ruled before the registration is approved, it is not allowed to apply for a ruling to cancel the registered trademark for the same facts and reasons.

after the Trademark Review and Adjudication Board makes an order to maintain or revoke a registered trademark, it shall notify the parties concerned in writing. If a party refuses to accept the ruling of the Trademark Review and Adjudication Board, he may bring a suit in a people's court within 3 days from the date of receiving the notice. The people's court shall notify the other party to the trademark adjudication procedure to participate in the proceedings as a third party.
