What is the international priority of utility model patents? What is the patent priority?

The priority of patent application means that after the patent applicant filed a patent application for his invention for the first time, he filed a patent application for the invention-creation with the same theme within the time limit stipulated in the patent law, and the date of filing the next patent application is the date of filing the first patent application. This right enjoyed by the applicant according to the patent law is called patent application priority. The main function of priority is to enable patent applicants to have enough time to consider whether to apply for a patent abroad after filing a patent application for the first time. If he applies for rights abroad, he still has enough time to choose a patent application agency and go through all necessary formalities. Applicants can also use this time to improve their patent applications without worrying about being preempted by others and losing their rights within the time stipulated in the patent law. The time limit stipulated in the patent law is also called the priority period. For example, "within twelve months" and "within six months" stipulated in Article 29 of the Patent Law, that is, "the applicant filed a patent application for an invention or utility model for the first time in a foreign country, or filed a patent application for a design with the same theme in China for the first time in a foreign country", are all legal time limits of priority. Article 29 Where an applicant applies for a patent for invention or utility model for the first time in a foreign country within twelve months, or applies for a patent for design for the first time in a foreign country within six months, and applies for a patent on the same subject in China, he may enjoy the priority in accordance with the agreement signed between that country and China or the international treaties to which both countries are parties, or in accordance with the principle of mutual recognition of priority. An applicant who files an application for a patent for invention or utility model with the administrative department for patent in the State Council within 12 months from the date when he first filed an application in China may enjoy priority. Article 30 Where an applicant claims priority, he shall make a written statement at the time of application and submit a copy of the patent application documents submitted for the first time within three months. Where the applicant fails to submit a written statement or fails to submit a copy of the patent application documents within the time limit, it shall be deemed that the priority has not been claimed.
