What is the specific process of applying for an invention patent?

According to the requirements of the patent law, an application for a patent for invention is to write the technical content that conforms to the authorized object of the patent law into a specified file format and submit it to the patent office after conforming to the specified language description rules. If the Patent Office finds no curve that does not conform to the relevant patent laws and regulations, it will grant the patent right to the request. The process of applying for a patent for invention is divided into five stages: acceptance stage, preliminary examination stage, publication stage, substantive examination stage and authorization stage. 1. At the patent acceptance stage, the Patent Office will examine the patent application after receiving it. If the conditions for acceptance are met, the Patent Office shall determine the date of application, give the application number, and after verifying the list of documents, issue an acceptance notice to inform the applicant. 2. The patent application accepted in the preliminary examination stage will automatically enter the preliminary examination stage if the application fee is paid in accordance with the regulations. Before the preliminary examination, the application for a patent for invention must be examined in secrecy, and if confidentiality is necessary, it shall be handled in accordance with the confidentiality procedures. In the preliminary examination, it is necessary to examine whether there are obvious deficiencies in the application, mainly including whether the contents of the examination fall within the scope of the patent law that does not grant patent rights, whether the obviously lacking technical contents cannot constitute a technical scheme, whether there is a lack of oneness, whether the application documents are complete and whether the format meets the requirements. 3. Publication stage The application for a patent for invention has entered the publication stage since the issuance of the notice of preliminary examination. If the applicant doesn't ask for disclosure in advance, it will take 18 months from the date of application to enter the public preparation procedure. If the applicant requests to be made public in advance, the application will immediately enter the public preparation procedure. After format review, editing and proofreading, computer processing and typesetting and printing, about three months later, the abstract of its instructions was published in the Patent Gazette and a brochure was published. After the application is published, the applicant has the right to temporary protection. 4. After the publication of the application for a patent for invention in the substantive examination stage, if the applicant puts forward a request for examination and it has taken effect, the applicant will enter the substantive examination procedure. If the applicant fails to make a request for substantive examination within three years from the date of application, or the request for substantive examination fails to take effect, the application shall be deemed to have been withdrawn. 5. In the authorization stage, if the application for a patent for invention is rejected after substantive examination, the examiner will make an authorization notice and apply for authorization registration preparation. After examining the legal effect and completeness of the authorized text, the Patent Office proofreads and modifies the description items of the patent application, and issues a notice of authorization and a notice of registration. After receiving the notice, the applicant shall go through the registration formalities in accordance with the requirements of the notice and pay the prescribed fees within two months. If the registration formalities are completed on schedule, the Patent Office will grant a patent right, issue a patent certificate, record it in the patent register, and announce it in the patent bulletin two months later. Those who go through the registration formalities in accordance with the provisions shall be deemed to have given up the right to obtain the patent right.
