2. Patent priority means that after a patent applicant first files a patent application in a certain country for his invention and creation, he files another patent application for the same subject invention and creation within the statutory period. According to the relevant The law stipulates that for subsequent applications, the date of the first patent application shall be regarded as the filing date. This right enjoyed by the patent applicant in accordance with the law is the right of priority. The purpose of patent priority is to exclude those who copy the patent in other countries and have the possibility to apply for it first and obtain registration. Patent priority can be divided into domestic priority and international priority. 1. Domestic priority Domestic priority, also known as "domestic priority", means that the patent applicant files another patent application in China within 12 months from the date of first filing a patent application for an invention or utility model with the same subject in China. Patent applications submitted by the Patent Office of the State Intellectual Property Office can enjoy priority. Design patents are not included in my country’s priority system. 2. International priority International priority, also known as "foreign priority", is as follows: within 12 months from the date when the patent applicant first files a patent application for an invention or utility model with the same subject in a foreign country, or If a patent application for a design with the same theme is first filed in a foreign country within 6 months from the first filing date of a patent application in China, China shall take the date of the first filing of a patent application in a foreign country as the filing date. That is the priority date.
