When does the term of the patent right with priority begin?

Legal analysis: the term of the patent right with priority is calculated from the fixed date such as the application date, the priority date and the authorization announcement date. Patent priority refers to the patent applicant filing a patent application for his invention and creation in China within the statutory time limit after filing a patent application in a country for the first time. According to the relevant laws and regulations, the date of the first patent application is regarded as the filing date of his later application, which is the right that the patent applicant enjoys according to law.

Legal basis: Article 29 of the Patent Law of People's Republic of China (PRC). Where an applicant files a patent application for an invention or utility model in China within 12 months from the date when he first filed a patent application with a foreign country, or within 6 months from the date when he first filed an application for a patent for a design with a foreign country, he may enjoy the priority according to the agreement signed between the foreign country and China or the international treaties to which he is a party, or according to the principle of mutual recognition of priority. Applicants who file a patent application for invention or utility model for the first time in China within 12 months, or apply for a patent for design for the first time in China within 6 months may enjoy priority.
