Legal analysis: There is no relationship between trademark invalidation and cancellation. They have different definitions and scope of application. Invalidity of a registered trademark refers to a situation where the exclusive right to a trademark that has been approved for registration is deemed to have ceased to exist from the beginning due to administrative decisions or rulings made by relevant authorities due to improper trademark registration. The revocation of a registered trademark refers to the system whereby the Trademark Office and the Trademark Review and Adjudication Board revoke a registered trademark in accordance with the law. It is sometimes referred to as trademark revocation.

Legal basis: Article 44 of the "Trademark Law of the People's Republic of China" has registered a trademark that violates Articles 4, 10, 11 and 12 of this Law. Article 19, paragraph 4, or if the registration is obtained by deception or other improper means, the Trademark Office shall declare the registered trademark invalid; other units or individuals may request the Trademark Review and Adjudication Board to declare the registered trademark invalid. When the Trademark Office makes a decision to declare a registered trademark invalid, it shall notify the parties concerned in writing. If the party concerned is dissatisfied with the decision of the Trademark Office, he may apply to the Trademark Review and Adjudication Board for review within fifteen days from the date of receipt of the notice. The Trademark Review and Adjudication Board shall make a decision within nine months from the date of receipt of the application and notify the parties in writing. If there are special circumstances that require an extension, it can be extended for three months with the approval of the industrial and commercial administration department of the State Council. If the party concerned is dissatisfied with the decision of the Trademark Review and Adjudication Board, it may file a lawsuit with the People's Court within thirty days from the date of receipt of the notice. If other units or individuals request the Trademark Review and Adjudication Board to declare a registered trademark invalid, the Trademark Review and Adjudication Board shall, after receiving the application, notify the relevant parties in writing and file a reply within a time limit. The Trademark Review and Adjudication Board shall make a ruling to maintain the registered trademark or declare the registered trademark invalid within nine months from the date of receipt of the application, and notify the parties in writing. If there are special circumstances that require an extension, it can be extended for three months with the approval of the industrial and commercial administration department of the State Council. If the party concerned is dissatisfied with the ruling of the Trademark Review and Adjudication Board, it may file a lawsuit with the People's Court within thirty days from the date of receipt of the notice.
