Firstly, prepare the application documents, including the request, the abstract of the specification, the claim, the specification and the attached drawings of the specification.
The second step is to submit the materials directly to the lobby of the patent office or the local patent agency window, or by mail.
Then, the State Patent Office issued a notice of acceptance and formally entered the examination and approval procedure.
Step 4: Pay the application fee. In addition to going directly to the toll office of the patent office and the agency of the patent office, you can also pay the application fee by remittance through the bank or post office.
Finally, the patent office only conducts a formal examination of the application for a patent for utility model, and the patent can be granted as long as it passes the preliminary examination.
The above is my answer to this question. I hope it helps you. Thank you.
