Domestic patent priority

Patent priority refers to the right to enjoy preferential treatment when applying for a patent in China. Generally speaking, this kind of right can be divided into two kinds, one is domestic priority and the other is international priority. The former means that the inventor can obtain domestic patent priority after submitting a patent application in the designated department of intellectual property application in China and filing a patent application with the same theme again within 12 months. Domestic patent priority is limited to utility model patents and invention patents. The latter kind of international priority actually means that the invention has filed a patent application for a certain subject in another country, and then filed a patent application for the same subject in China within 12 months according to the agreement signed between China and that country or the international treaty to which China is a party, so that it can enjoy international priority. Only if the patent type is design, the time limit is only six months. When the inventor meets the above two conditions, he can naturally obtain the patent priority of China.
