The trademark registration certificate is valid. The period of validity of a registered trademark is ten years, counting from the date of approval of registration. Where it is necessary to continue to use a registered trademark after the expiration of the validity period, it shall apply for trademark renewal, and the renewal of registration shall be handled within 12 months before the expiration of the validity period.

Trademark renewal can be handled by itself or by entrusting a trademark agency. If you entrust a trademark agency, you only need to prepare relevant application materials. Information required for trademark renewal:

1. Application for trademark renewal registration; 2. Power of attorney; 3. Copy of business license with official seal (provided by the company) and copy of ID card (provided by individuals); 4. Copy of trademark registration.

Matters needing attention in trademark renewal:

1. After the renewal application is approved, the Trademark Office will mail the renewal certificate to the applicant according to the address filled in the application.

2. If the application for renewal does not meet the requirements, the Trademark Office will notify the applicant in writing by post to make corrections within a time limit according to the address filled in the application.

3. If the renewal application cannot be approved for other reasons, the Trademark Office will notify the applicant in writing by post according to the address filled in the application.

If the applicant entrusts a trademark agency to apply for renewal, the Trademark Office will not have any direct contact with the applicant, and all documents will be sent to the trademark agency.

5. The category of application shall be filled in according to the international classification approved by the Trademark Registration Certificate.
