What do you mean by foreign priority of patent right?

The so-called foreign priority means that an applicant applies for a patent for an invention or utility model for the first time in a foreign country within 12 months, or for a design for the first time in a foreign country within 6 months, and applies for a patent for the same subject in China, according to the agreement signed by the foreign country and China, the international treaties to which the two countries are parties, or the principle of mutual recognition of priority, that is, the date when he first applied in a foreign country. The principle is also applicable to patent applications filed by China applicants abroad. The distinction between domestic priority and foreign priority mainly includes the following four aspects: 1. The scope of priority is different: after the first application in a foreign country, a foreign applicant can apply for a patent for invention, utility model or design with the same theme in China and enjoy priority. 2. The subjects of priority are different: foreign priority is enjoyed by foreign citizens and domestic priority is enjoyed by domestic citizens. 3. Different sources of rights: foreign priority comes from the agreement signed between foreign countries and China or the international treaties to which both countries are parties, while domestic priority is given to qualified applicants according to the provisions of China's patent law. 4. The purpose of priority setting is different: foreign priority provides convenience for international patent application and protects the interests of foreign patentees in time and effectively; Domestic priority is mainly for the convenience of adding technical solutions during the priority period, providing conditions for the conversion between different types of patents and protecting domestic citizens.
