Legal analysis: If the trademark owner finds that his trademark right has been infringed, he can negotiate with the infringer about compensation. If negotiation fails, he can also bring a lawsuit to the court. According to the provisions of China's Trademark Law, if the other party encroaches on the trademark right, the prior obligee or interested party may request the Trademark Review and Adjudication Board to declare the registered trademark invalid.

legal basis: if the registered trademark in article 45 of the trademark law of the people's Republic of China violates the provisions of paragraphs 2 and 3 of article 13, paragraph 1 of article 15, article 3, article 31 and article 32 of this law, the prior obligee or interested party may request the trademark review and adjudication board to declare the registered trademark invalid 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. After receiving an application to declare a registered trademark invalid, the Trademark Review and Adjudication Board shall notify the parties concerned in writing and file a reply within a time limit. The Trademark Review and Adjudication Board shall, within 12 months from the date of receiving the application, make an order to maintain the registered trademark or declare it invalid, and notify the parties concerned in writing. There are special circumstances that need to be extended, which can be extended for six months with the approval of the administrative department for industry and commerce of the State Council. 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. In the process of examining the request for invalidation in accordance with the provisions of the preceding paragraph, the Trademark Review and Adjudication Board may suspend the examination if the determination of the prior rights involved must be based on the result of another case being tried by the people's court or being handled by the administrative organ. After the reasons for suspension are eliminated, the review procedure shall be resumed.
