Trademark renewal is about 10 months after expiration. An application for trademark renewal, a power of attorney for renewal and a copy of the registrant's business license are required. A successfully registered trademark is valid for ten years, and there is no need to pay any royalties. After the expiration, if the trademark continues to be used, it can be renewed. The renewal needs to provide a copy of the business license and official seal, an application for trademark renewal and a power of attorney. The Trademark Office charges 2000 yuan per piece. Trademark applicants may apply for renewal six months before the expiration of the period. If they forget, they can apply for renewal within six months after the expiration. This is an extension. The Trademark Office charges 2500 yuan per piece. If the extension period is not extended, the trademark is invalid.

Trademark renewal registration process:

1. Prepare the application documents and submit the trademark renewal registration application to the official. 1-3 working days

2. The Trademark Office issues the renewal certificate of registered trademark. About 3-6 months' working time.
