Legal analysis: the reasons are different: the reasons for revocation include changing the registered trademark or trademark registration items by oneself; Transferring a registered trademark by itself; Stop using it for three consecutive years; Goods using registered trademarks are shoddy and deceive consumers. Invalidation is due to the lack of absolute conditions for registration; Infringement of prior rights; The registrant violated honest business practices. Different time limits: you can apply for revocation of trademark rights if there are reasons for revocation. Because of the uncertainty of the reasons for cancellation, you can't set the time limit for applying for cancellation. In the absence of absolute conditions for trademark registration, the Trademark Office may request the Trademark Review and Adjudication Board to declare the trademark invalid ex officio or by other units or individuals without time limit; The right of the prior obligee to request invalidation must be exercised within a certain period of time, and most countries stipulate that it should be filed within five years from the date of trademark registration. The legal consequences are different: the revocable reason occurs after the trademark right is obtained, and the revoked trademark right becomes invalid after revocation. The cause of invalidity existed when the trademark right was obtained, and the trademark right that was declared invalid was invalid from the beginning.
