Patent application is a necessary procedure for obtaining patent right. To obtain a patent right, the applicant shall file an application with the State Patent Office, which shall approve and issue a certificate. When filing a patent application with the State Patent Office, the applicant shall also submit a series of application documents, such as the request, specification, abstract and patent claim. In terms of patent application, the provisions of the patent laws of all countries in the world are relatively consistent, but there are also many differences.
A patent application is a request made by an inventor, designer or other subject who has the right to apply to the Patent Office for a patent right for invention or design. According to the provisions of China's patent law, an application for a patent shall be submitted to the Patent Office with an application, specification, patent claim, abstract, drawings and a request for priority. Among them, the appended drawings and priority claims are not essential to every application, but they are beneficial to patent applications. A patent application shall be in written form, mainly including the following contents: the request, the name of the invention or design, the name and identity of the applicant, the name and identity of the agent and the signature.
Article 28 of the Patent Law of People's Republic of China (PRC) The date when the patent administrative department of the State Council receives the patent application documents shall be the filing date. If the application documents are mailed, the postmark date of mailing shall be the application date.
Article 29 Where an applicant applies for a patent for invention or utility model for the first time in a foreign country within twelve months, or applies for a patent for design for the first time in a foreign country within six months, and applies for a patent on the same subject in China, he may enjoy the priority in accordance with the agreement signed between that country and China or the international treaties to which both countries are parties, or in accordance with 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.
