Paragraph 2 of Article 29 of the Patent Law stipulates the domestic priority of patent right. Applicants who apply for a patent for invention or utility model for the first time in China within twelve months, or apply for a patent for design for the first time in China within six months, may enjoy priority. The purpose of patent priority is to exclude the possibility that anyone who plagiarizes this patent in other countries may first apply and get registered.

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.
