The process of applying for a patent invention prepares application documents, including the description of the request, the description of the claim, the description of the drawings, and a brief description of the design patent. You can get the corresponding form at the service point of the National Patent Office.
The patent office shall first make a preliminary examination of the application. For patent applications other than inventions, as long as they pass the preliminary examination, patents can be granted, and unqualified amendments will be resubmitted. After the examination, the substantive examination will be carried out, and only through the substantive examination can the patent be obtained.
