I. Conditions for applying for priority
1. The prerequisite for claiming priority is that an application has been formally filed in a member state. The so-called normal domestic application refers to all applications in the country where the application date can be determined, regardless of the application result. Any application that belongs to a normal country according to the domestic law of any member country or the provisions of bilateral or multilateral treaties signed between member countries.
2. The priority application period for invention patents and utility models is 12 months, and the priority application period for designs and trademarks is 6 months. The above period is counted from the date of the first application, and the date of application is not counted in the period. If the last day of the deadline is a legal holiday in the requested country, or the competent authority fails to file an application on that day, the deadline shall be extended to the first working day thereafter.
3. When an application with the same contents as the first application is later filed in the same country, if the previous application has been withdrawn, abandoned or rejected, and has not been provided to the public for review, and has not left any pending rights, the latter application shall be regarded as the first application. The date of application should be the starting date of the priority period, and the earlier application cannot be used as the basis for requesting priority. If the application for design is filed in a country according to the priority based on the application for utility model, the priority period shall be the same as that stipulated by the design; In a country, based on the priority of invention patent application, it is also allowed to file a utility model application in a country, and vice versa. The time limit of the priority application shall be subject to the time limit of the application.
