Answer: The reason for trademark renewal is that when you submitted your trademark application, some of the content or materials did not meet the requirements. The purpose of making corrections is to make your application meet the requirements and ultimately make your application successful. Trademark correction only requires that correct information be submitted back to the Trademark Office. If a trademark registration applicant or registrant discovers that there are obvious errors in the trademark application documents or registration documents, they may apply for correction. The corrected errors are limited to individual text errors in the name, address, products and other items in the application documents or registration documents, and do not involve substantive content. Applicants/registrants and agency organizations that submit trademark correction applications to the Trademark Office must fill out the "Application for Correction of Trademark/Registration Matters Application". Information required for trademark correction: 1. Application for correction of trademark/registration matters. 2. A copy of the identity document (copy of business license, ID card, etc.) of the trademark registrant confirmed by seal or signature. 3. If the registrant's name and address are corrected after the change is completed, the original "Change Certificate" should be returned at the same time. 4. If the name and address of the transferee registrant are corrected after the transfer is completed, the original "Transfer Certificate" should be returned at the same time. 5. If the correction of erroneous information results in changes to the "Trademark Registration Certificate", the original "Trademark Registration Certificate" should be returned at the same time.
