Trademark division application means: a trademark applicant can request to divide his or her trademark application. The filing date of the original application shall continue to apply to each divided application. The applicant cannot withdraw its request for partition.

Before May 1, 2014, my country adopted the "one mark, one category" approach in the trademark application process, that is, the applicant could only apply for trademark registration for the same category of goods in one application. , cross-category applications are not allowed. In the third revision of the Trademark Law, in order to provide better services to Chinese and foreign trademark applicants and strive to bring trademark work to international standards, the relevant revision units have stipulated in the current Trademark Law that trademark applications allow "one mark for multiple categories" ", cross-class application", which stipulates: "The Trademark Office may promptly accept applications for registration of the same trademark in multiple product categories in one application." For "multi-class, cross-class application for one mark", the trademark division system is adopted. It is an important supporting measure. Countries and regions that allow cross-class trademark applications, such as Japan, Germany, Australia, the United Kingdom and Taiwan, all have a positive attitude towards trademark split.
