Article 22 of the "Regulations for the Implementation of the Trademark Law" stipulates: If the Trademark Office rejects a trademark registration application for some designated goods, the applicant may divide the preliminary approved part of the application into For another application, the divided application retains the filing date of the original application.

When an applicant wants to fight for the right to reject a product item through the reexamination process, he or she can choose whether to split the trademark according to his or her own circumstances. If division is required, the applicant can file an application for division within 15 days after receiving the partial rejection notice. After receiving the division application, the Trademark Office will generate a new application number for the preliminary approved part and directly announce it; the original part of the rejected product item will be retained. The application number will continue to enter the review and review stage. When the applicant gives up the rejection of the product item, he does not need to submit a division application and waits for the completion of the 15-day legal procedure for rejection review. The Trademark Office will announce the preliminary review.

It can be seen that trademark division is to divide one trademark into two trademarks, and the division can only be carried out in the trademark partial rejection procedure, and cannot be divided in other procedures.
