How long after the patent application?

After the patent application, it will generally be published after 18 months.

According to the law, after receiving a patent application, the State Council Patent Administration Department can publish it after 18 months from the date of application if it meets the requirements after preliminary examination.

The process of patent application:

1, Filling and Writing of Patent Application Documents

There are specific requirements for the filling and writing of patent application documents, and the applicant can fill in and write them by himself or entrust a patent agency to handle them on his behalf. Although it is not mandatory to entrust a patent agency, considering the importance of carefully writing patent application documents and the legal rigor of examination and approval procedures, it is worth promoting for applicants with little experience.

2. Acceptance of patent applications

After receiving the patent application, the Patent Office's acceptance office or the Patent Office's agency shall determine the application date, give the application number and issue a notice of acceptance for the application that meets the acceptance conditions.

3. Pay the application fee

Those who submit the patent application documents in person may pay the application fee after obtaining the notification of acceptance and the notification of payment of the application fee. If an application is submitted by mail, the application fee shall be paid after receiving the notification of acceptance and the notification of payment of the application fee, because the application fee needs to be paid with the corresponding application number, but the date of payment of the application fee shall not exceed two months from the date of application at the latest.

4. Patent approval procedures

According to the law, the examination and approval procedure of an application for a patent for invention includes five stages: acceptance, preliminary examination, publication, actual examination and authorization. When examining and approving an application for a patent for utility model or design, there are only three stages: acceptance, preliminary examination and authorization.

5. Actively modify and correct the patent application documents.

The active revision and correction of patent application documents is also a procedure that applicants can choose according to their needs. Applications for patents for utility models and designs are only allowed to be modified voluntarily within two months from the date of application; An application for a patent for invention is only allowed to actively modify the patent application documents within three months from the date of filing a request for substantive examination and receiving a notice from the Patent Office that the application for a patent for invention has entered the substantive examination stage.

6. The application was rejected

If the applicant for a patent refuses to accept the decision of the patent administrative department of the State Council to reject the application, he may, within three months from the date of receiving the notice, request a reexamination with the Patent Reexamination Board. The reexamination procedure is an error correction procedure, which prevents the patent application that should be approved separately from being approved due to the examiner's level, experience and misunderstanding of the law, and provides a legal remedy for the patent applicant. After reexamination, the Patent Reexamination Board shall make a decision and notify the patent applicant. If the patent applicant refuses to accept the reexamination decision of the Patent Reexamination Board, he may bring a lawsuit to the people's court within three months from the date of receiving the notice.

Legal basis: Article 34 of the Patent Law of People's Republic of China (PRC).

After receiving an application for a patent for invention, the administrative department for patent in the State Council, after preliminary examination, finds that it conforms to the provisions of this Law, and shall publish it immediately after 18 months from the date of application.

The patent administration department of the State Council may publish its application at an early date upon the request of the applicant.

Article 35

Within three years from the date of filing, the patent administration department of the State Council may conduct substantive examination according to the request made by the applicant at any time; If the applicant fails to request substantive examination within the time limit without justifiable reasons, the application shall be deemed to have been withdrawn.

The patent administrative department of the State Council may, when it deems it necessary, examine the application for a patent for invention on its own.
