1, where two or more applicants for trademark registration apply for registration with the same or similar trademarks on the same commodity or similar commodities, the trademark applied earlier shall be preliminarily examined and approved and announced; Where an application is filed on the same day, the prior trademark shall be preliminarily examined and announced, and the application of others shall be rejected without announcement. 2. Therefore, the registered trademarks applied by two people on the same product are similar, and China adopts the principle of first application. If the application is filed on the same day, China stipulates that the applicant who first uses the trademark has the right to register the trademark. Legal basis: Article 31 of the Trademark Law of People's Republic of China (PRC), if two or more applicants for trademark registration apply for registration with the same or similar trademarks on the same or similar goods, the trademark applied earlier shall be preliminarily examined and announced; Where an application is filed on the same day, the prior trademark shall be preliminarily examined and announced, and the application of others shall be rejected without announcement. Article 32 An application for trademark registration shall not damage the prior rights of others, nor shall it preempt the registration of a trademark that has been used by others and has certain influence by unfair means. Article 33 If, within three months from the date of the announcement of preliminary examination and approval, the prior obligee or interested party thinks that the trademark violates the provisions of Article 13, paragraph 2, paragraph 3, Article 15, Article 16, paragraph 1, Article 30, Article 31 and Article 32 of this Law, or that it violates the provisions of Article 10, Article 11 and Article 12 of this Law, it may file an objection with the Trademark Office. If there is no objection at the expiration of the announcement period, the registration shall be approved, a trademark registration certificate shall be issued and an announcement shall be made.
