What are the steps of patent application (write it yourself and vote for it yourself)? What processes need our participation? Please be more detailed, thank you ~ ~

Write a patent document and mail it to China National Intellectual Property Administration or the provincial intellectual property situation in your provincial capital, then pay the fee (fill in the fee mitigation certificate, download the template to China National Intellectual Property Administration website), then wait for his authorization notice (letter), then pay the certification fee, and wait for the certificate to be mailed three months later, that's all.

Of course, if you are a utility model, the file format and content should meet the standards, otherwise he will inform you to make corrections by letter after receiving the application documents. (About 8 months from application to license)

If you are an invention, there will be censorship opinions, that is, he will ask some questions that he thinks cannot be authorized. You need to convince him with words. It is possible to give you five or six evaluation opinions, and answering the evaluation opinions is more professional. If it is an invention, it is recommended not to write it yourself. Find an intermediary. (It takes about 2-3 years from application to license)
