A: If the Trademark Registration Certificate is lost, it needs to be reissued. It is very simple to reissue the trademark registration certificate. There are two ways to apply for a new Trademark Registration Certificate: 1. If an agency is entrusted, a copy of the business license shall be provided. The application for renewal of trademark registration certificate and the power of attorney shall be prepared by the agency and signed and sealed by the applicant. 2. If the applicant goes directly to the trademark registration hall of the Trademark Office, he shall fill in the Application for Reissuing the Trademark Registration Certificate, a copy of the business license of the trademark registrant, and the original and copy of the agent's ID card. 3.
