What is the process of applying for a patent independently?

First, you need to register an account for patent electronic application, then download the patent electronic application client and the patent electronic application key, record the fee reduction (annual income is less than 60,000), write the application document, submit the patent application through the patent electronic application client, pay the patent application fee, reply and make corrections (if there is no problem with the patent application document, there is no need to reply and make corrections), and pay the annual fee and stamp duty to obtain the patent certificate.
