Article 3 1 of China's Trademark Law clearly stipulates: "If 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 announced; If the application is made on the same day, the prior trademark will be preliminarily examined and announced, and the application of others will not be announced and rejected. " Therefore, the principle of first application is adopted for the registration of identical or similar trademarks. That is, the Trademark Office granted the exclusive right to use a trademark to the first applicant. If two people apply on the same day, the Trademark Office will grant the exclusive right to use the trademark to the applicant who first uses the trademark.
