The first paragraph is the first two, indicating the year when the patent application was filed, for example, 97 means 1997. The second paragraph consists of the third digit, indicating the type of patent application, and 1 indicates invention (if it is utility model 2, design 3, PCT invention patent application 8, 9PCT utility model patent application); The third paragraph consists of the fourth to eighth digits, indicating the serial number of this kind of application in the current year, for example, 0 1765 indicates the application in the current year 1765; The fourth paragraph consists of a number or symbol of the ninth bit, which is a check bit automatically generated by the computer. It can be any number or character x between 0 and 9, such as 4 in this example. Since 2002, the basic format of patent number is 20021000001.1,and the first paragraph of 2002 is 2002; The second paragraph consists of the fifth digit, indicating the application type; The third paragraph consists of the sixth to twelfth digits, representing the application serial number of that year (the increase in figures represents the increase in the number of applications in recent years, which is really gratifying and encouraging; On the other hand, it has indeed increased the workload and extended the time for the Intellectual Property Office); The fourth paragraph consists of the last digit or symbol, which is a check bit automatically generated by the computer and given by the computer.

For example, the patent number granted by XXX is ZL2003 10 100002.
