You need to write your own patent documents and fill in the application documents. When submitting a patent application, you can submit it in person or mail it to China National Intellectual Property Administration. Of course, you can also submit a patent application online through electronic channels, but you must open an account electronically before you can submit a patent application electronically. Electronic account opening procedures are handled in China National Intellectual Property Administration or the local intellectual property office.
2. Entrust a patent agency
You can entrust a patent agency with patent agency qualification to apply for a patent and let them provide "one-stop" service. You just need to provide technical information.
Without the basic qualities related to patents, it is really difficult to guarantee the quality of application documents.
Considering the real use potential of the invention, it is suggested to find an agency to do it or to study and write the application documents yourself.
If you want to know whether it meets the standards, you need to apply for a basic understanding of the document requirements. It is suggested that the website of the Intellectual Property Office look at the relevant requirements and study the patent examination guide.
