What is the process and time for Hefei to apply for a patent?

According to the relevant provisions of China's patent law, there are two procedures for a patent from application to authorization. 1. Hefei invention patent granting procedure includes six stages: application → acceptance (application number and date) → preliminary examination → publication → substantive examination → authorization and issuance (announcement, the patent is valid for 20 years). Second, there are four stages: application → acceptance (application number, application date) → preliminary examination → authorization to issue certificates (announcement, patent validity period 10 year). Compared with the invention patent, there is no publication and substantive examination procedure in the application procedure of utility model or design patent, but it can be directly authorized after preliminary examination. Details of each stage are as follows: 1. The documents to be submitted when applying for a patent for invention and utility model include the request, the patent claim, the specification, the appended drawings of the specification, the abstract of the specification and other documents. The documents to be submitted when applying for a patent for design include a request, pictures or photographs, a brief description and other relevant documents. 2. After receiving the patent application documents, China National Intellectual Property Administration Patent Office will issue a notice of acceptance, determine the date of patent application and give the patent application number. For the lack of necessary application documents or other violations of legal provisions, it will not be accepted. 3. After receiving the application documents, the preliminary examination patent office shall first conduct a formal examination of the application documents and pay the fees. If the preliminary examination fails, the applicant shall make corrections or statements in accordance with the notice; If it still does not meet the requirements, it shall be rejected. If the application for a patent for utility model or design has passed the preliminary examination and no reason for rejection is found, it will directly enter the authorization procedure for authorization. 4. Publication (unique to the application for a patent for invention) If the application for a patent for invention has passed the preliminary examination, it will enter this stage. If the Patent Office considers that it meets the requirements of the Patent Law after preliminary examination, it shall publish it in the bulletin of invention patent within 18 months from the date of application. The Patent Office may also publish its application at an early date upon the request of the applicant. 5. Substantive examination (unique to an application for a patent for invention) Within 3 years from the date of application, the Patent Office may, at the request of the applicant at any time, conduct a substantive examination of its application. If the applicant fails to make a request within this time limit, his application will be deemed to have been withdrawn. However, if the request cannot be made in time due to force majeure or other legitimate reasons, a certificate may be issued before the request is made. When the Patent Office deems it necessary, it may also conduct substantive examination of the application for a patent for invention on its own. 6. After the actual examination of the application for a patent for invention, if the patent for utility model and design is not found to be rejected after the preliminary examination, the patent right shall be granted and a patent certificate shall be issued. A patent authorized and issued with a patent certificate shall be registered in the Bulletin of Invention Patents, and the patent right shall take effect as of the date of announcement. The specific work and time period of each process are: 1. Both utility model patents and invention patents need to be written. The authorization period of utility model patent application is generally about 1 year. After submitting the application, you can get the patent acceptance notice in about a week; About six to eight months, the patent office will issue a notice of granting the patent right for utility models and a notice of handling registration procedures; After paying the patent registration fee and annual fee, the license can be issued in about two months. If an application for a patent for utility model is processed after 1 month from the date of filing, it will generally be granted in about 6 months. The authorization period of an application for a patent for invention is generally about 3-5 years, and there is no clear time limit for examination and approval in law. After submitting the application, you can get the patent acceptance notice in about a week; In the preliminary examination stage, if it is qualified, the specification of the patent application will be made public according to the early public statement, and it will enter the substantive examination stage; Those who pass the actual examination shall be issued with the Notice of Granting Invention Patent Right and the Notice of Handling Registration Procedures; After timely payment, the certificate will be issued in about two months, so it usually takes about three years for the invention patent application process to be smooth. To sum up, the specific requirements of Hefei local audit institutions should also be taken into account in the specific provisions of Hefei patent application process and time. For example, the requirements for specific materials for handling this patent may be different. We should collect and present the patent legal documents according to our actual needs, so as to better and faster solve our patent application needs.
