As the Patent Law stipulates that the invention patent will only undergo substantive examination after the patent specification of the application is made public, the purpose of submitting an early public statement is to enter the substantive examination as soon as possible, thus shortening the period of patent application.
Therefore, the invention patent also needs to submit two documents: the request for prior public statement and the request for substantive examination.
After submitting an application for a patent for invention, you can get a notice of patent acceptance in about a week; After the application is submitted, the preliminary examination stage will be carried out. If it is qualified, the specification of the applied patent will be disclosed in advance according to the public statement, that is, it will enter the substantive examination stage; Those who pass the actual examination shall be issued a Notice of Granting Invention Patent Right and a Notice of Handling Registration Procedures.
After timely payment, it will take about two months to issue the certificate.
The application process of invention patent takes about three years.
Individuals applying for invention patents (Chinese mainland individuals only) may submit an application for fee reduction and exemption together, requesting to reduce the application fee and the annual fee for the first three years.
