1. Invalidation: Others may file a request for invalidation with the Trademark Registration Office, requesting cancellation of the registered trademark. The reasons for invalidation include but are not limited to the lack of distinctiveness of trademarks, high similarity with existing trademarks and possible confusion.
2. Infringement complaint: If the trademark registrant fails to use the trademark legally, or infringes upon the legitimate rights and interests of others after the trademark registration, others may file an infringement complaint with the Trademark Office and request the cancellation of the trademark registration.
3. Unused cancellation: In some countries or regions, if the trademark has not been used for a period of time after registration, others may request the cancellation of the unused trademark to cancel the registration.
4. Malicious registration and revocation: A trademark registrant registers a trademark by malicious means. If someone intentionally grabs another person's existing trademark, the other party may make a request for malicious registration and revocation, requesting to cancel the maliciously registered trademark.
It should be noted that trademark revocation requests usually need to meet certain legal procedures and requirements and need to provide sufficient evidence to support them. The revocation of trademark registration is not a simple process, which requires the examination and decision of relevant institutions.
Therefore, although trademark registration provides certain rights and interests protection, under certain circumstances, trademark registration may still be revoked by others. Trademark registrants should legally use trademarks and strictly abide by laws and regulations related to trademarks in order to protect the legitimacy and effectiveness of their trademark registration.
