The trademark registration invalidation system refers to a system in which a trademark can be declared invalid after registration if it is found to have violated relevant laws and regulations or infringed on the rights of others. Specifically, a trademark may be declared invalid under the following circumstances:

Violation of relevant laws and regulations. If there are violations of relevant laws and regulations during the trademark registration process, such as violation of the Trademark Law, Anti-Unfair Competition Law, etc., the trademark may be declared invalid.

Violate the rights of others. If a trademark infringes upon the prior rights of others, such as copyrights, patents, etc., the trademark may be declared invalid.

Malicious registration. If a trademark applicant maliciously registers someone else's trademark, the trademark may be declared invalid.

Violation of the principle of good faith. If a trademark applicant violates the principle of good faith, such as forging application materials, fabricating facts, etc., the trademark may be declared invalid.

If you believe that a trademark infringes upon your rights or violates relevant laws and regulations, you can file an objection with the Trademark Office or apply for an invalidation declaration. At the same time, you can also strengthen your awareness of self-protection and prevent your trademarks from being invalidated by establishing a complete intellectual property management system and strengthening publicity and education.
