Trademark cancellation includes three situations: (1) Cancellation due to violation of trademark law. There are three situations: first, the trademark owner changes the text or graphics of the registered trademark, or changes the registrant's name, address, and other registration matters; second, the registered trademark is transferred by the trademark owner, or the registered trademark is stopped for three consecutive years. In this regard, the Trademark Office has the right to cancel the registered trademark. (2) Dispute withdrawn. According to China’s Trademark Law, if the trademarks disputed by several parties are indeed the same or similar, the Trademark Review and Adjudication Board will rule to revoke the trademark of the later-registered party and maintain the exclusive rights of the first-registered party. (3) Cancellation if not used for three years. According to the provisions of the Trademark Law, if a trademark applied for registration has not been used for more than three years, any third party may apply for invalidation of the trademark.
