The principle of prior application, also known as the principle of prior registration, means that two or more applicants for trademark registration apply for registration with the same or similar trademark on the same or similar goods, and the applicant who applies for the trademark first can obtain the exclusive right to use the trademark, and the subsequent application for trademark registration will be rejected. If the application is made on the same day, the prior trademark shall be preliminarily examined and announced, and the application of others shall be rejected without announcement; If it is used or not used on the same day, the applicant can settle it through consultation. If negotiation fails, the applicant will draw lots to decide.
