Legal subjectivity:

If the trademark expires, the trademark owner can apply for trademark renewal procedures. Renewal is generally filed twelve months before the expiration of trademark rights, but the law provides a six-month extension period. That is to say, the trademark owner can still apply for renewal six months after expiration. After successful registration renewal, the trademark right can be extended for another ten years, which period is calculated from the end of the last validity period. Documents that the trademark owner needs to submit when applying for renewal: 1. Renewal application. 2. Relevant identity information materials of the parties, including the parties’ ID number, name, address, etc. 3. Trademark registration certificate. 4. Other documents and materials required by law. Legal objectivity:

Article 40 of the "Trademark Law" If a registered trademark has expired and needs to be continued to be used, the trademark registrant shall go through the renewal procedures in accordance with the regulations within twelve months before the expiration; here If the application cannot be processed within the period, a six-month extension period can be given. Each renewal of registration is valid for ten years, starting from the day after the expiration of the previous term of validity of the trademark. If renewal procedures are not completed upon expiration, the registered trademark will be cancelled. The Trademark Office shall announce the renewal of registered trademarks.
