Foreign priority of patent

1, domestic priority means that an applicant who applies for the same subject again in his own country within a certain period of time after filing his first application in his own country can enjoy the priority of the first application. The scope of application of domestic priority is limited to the application for patents for inventions and utility models. Domestic priority is the same as foreign priority in terms of priority period, the applicant's qualification to claim priority and the conditions for establishing priority claim. 2. The so-called foreign priority refers to the fact that the applicant filed an application for a patent for invention or utility model for the first time in a foreign country within 12 months, or filed an application for a patent for design for the first time in a foreign country within 6 months, and filed a patent application for the same subject in China, which can be based on the agreement signed between the foreign country and China, the international treaty to which * * * is a party, or the principle of mutual recognition of priority, that is, the applicant enjoys the priority for the first time in a foreign country. The principle is also applicable to patent applications filed by China applicants abroad. I hope it will help you, hope to adopt it, and welcome to ask.
