What is the patent application number? What's the difference between patent application number and patent number? To understand the difference between patent serial numbers, we must first understand the origin of patent serial numbers. Let me introduce you to the difference between patent application number and patent number.
After the patent applicant obtains the patent right, the patent number on the patent certificate issued by China National Intellectual Property Administration is ZL (patent initials)+application number. The application number refers to the patent applicant who filed a patent application in China National Intellectual Property Administration. China National Intellectual Property Administration gave a notice of acceptance of the patent application, and the patent application number was given when the patent right was granted, which is a contribution number. The submission number is the serial number compiled by each industrial property office when publishing patent documents (including public publication and reading and copying only).
There are more and more inquiries about the patent number, which proves that people pay more and more attention to the authenticity of the patent number. However, the patent number in China is basically divided into the following two situations: the patent number before 2002 is divided into four sections: for example, 97 10 1765.4. The first paragraph is the first two paragraphs, indicating the year when the patent application was filed, such as "97" for 1999. 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" and PCT utility model patent application "9"); The third paragraph consists of four to eight digits, indicating the serial number of such applications in the current year.

The patent number of the patent that has been authorized, that is, the patent number on the authorization certificate issued by China National Intellectual Property Administration, is the application number in front of ZL. For example, the patent number granted by XXX is ZL [1* * * * * *] 2. The patent number begins with the first letter "ZL" of its Chinese phonetic alphabet, followed by nine digits and a decimal point, in which the first two digits of the first eight digits of the decimal point indicate the year of patent application; The third digit indicates the category of the patent application.
1 is an invention, 2 is a utility model, and 3 is a design; The fourth to eighth digits represent the serial number of this kind of patent application in that year; The number after the decimal point is the computer check number, which is the remainder obtained by multiplying the first eight digits by 2, 3, 4, 5, 6, 7, 8 and 9 in turn, adding the sum of their products, and then dividing by 1 1. When the remainder is 10, it is represented by X.
