How long does it take for a patent to be approved

The approval procedures and cycles for invention patents are different from utility models and designs. Invention patents must go through the stages of acceptance, preliminary examination, early disclosure, substantive examination, and authorization announcement. Utility models and designs only go through three stages: acceptance, preliminary examination and authorization announcement.

After the application is published, the applicant obtains the right to temporary protection, which means that from the date of publication of the application, the applicant can require the unit or individual who implements his invention to pay fees. After the application is published, the content recorded in the application becomes part of the prior art.

"Patent Law" Article 35 Inventions Within three years from the filing date of a patent application, the patent administration department of the State Council may conduct a substantive examination of the application based on the request made by the applicant at any time; if the applicant fails to request a substantive examination beyond the time limit without justifiable reasons, the application will be deemed to have been withdrawn.

When the patent administration department of the State Council deems it necessary, it may Conduct substantive examination of invention patent applications on their own.
