Priority date:
Priority date is a special concept under the patent law. Under Article 29 of the Patent Law of People’s Republic of China, Where an applicant, within twelve months from the date of first-filed patent application for an invention or utility model in a foreign country or within six months from the date of the first-filed patent application for a design in a foreign country, also files a patent application for the same subject in China, he/it may enjoy priority in accordance with the agreement entered into between the foreign country and China or the international treaty participated by both the foreign country and China or under the principle of mutual recognition of priority. Where an applicant, within twelve months from the date of the first submission in China of an application for a patent for invention or utility model, or within six months from the date of the first submission in China of an application for a patent for design, also files an application for a patent for the same subject with the patent administrative department under the State Council, he/it may enjoy priority.
If a patent has a priority date, the materials should prove that the prior use occurred prior to the priority date. If you cannot identify the priority date on the patent license, you can check it on the patent inquiry website.
