If an individual's business license is cancelled, the relevant personnel need to provide the cancellation certificate within one year after the cancellation of the business license and the liquidation report filed with the competent authority to determine the ownership of the trademark, otherwise it will become a dead mark and have no legal effect. Article 50 of the Trademark Law stipulates that if a registered trademark is revoked, declared invalid or will not be renewed upon expiration, the Trademark Office shall not approve an application for trademark registration that is the same as or similar to the trademark within one year from the date of revocation, invalidation or cancellation.
