In the application number, the first to fourth digits indicate the year when the patent application was accepted.
The fifth digit indicates the type of patent application: 1- invention, 2- utility model, 3- design, 8- international application for national phase invention patent in China and 9- international application for national phase utility model patent in China.
The sixth to twelfth digits (***7 digits) indicate the application serial number of the current year, and the thirteenth digit after the decimal point is the computer check code.
