Do I need to apply for a replacement if the trademark transfer approval certificate is lost? I believe you may encounter this situation, so I will explain the solution here. Approval of the trademark transfer certificate means that after the trademark transferee and the trademark transferor reach a trademark transfer agreement, the trademark transferee submits a registered trademark transfer application to the National Trademark Office. If the registered trademark transfer is approved by the National Trademark Office, the Trademark Office will submit the trademark transfer application to the trademark transferee. Have someone issue a trademark transfer approval certificate. The trademark transfer approval certificate must be used together with the original Trademark Registration Certificate. A simple understanding is a written proof of approval of trademark transfer. Solution: If the trademark transfer approval certificate is lost, you do not need to apply for a new trademark transfer certificate. You can just apply for a new trademark registration certificate. Of course, it will take a long time, about 6 months. If you want to use it, just use the new trademark registration certificate.
