Pay attention to write down the application number when paying, and ask the staff of the bank or post office to input the patent application number, name, address, zip code, etc. But you shouldn't send cash directly to the patent office. No one will accept it. Pay attention to the payment within 15 working days from the date of receiving the admission notice. (5) The Patent Office shall first conduct a preliminary examination of the application. For patent applications other than inventions, patents can be granted as long as they pass the preliminary examination, and unqualified amendments can be resubmitted.

Only after substantive examination can a patent be obtained. Some substantive audits can be carried out immediately, while others can only be carried out after 18 days.
