What is the patent number? What's the difference between patent number and application number?

The patent number is the number given when the patent right is granted, and it is a submission 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).

1, the content is different.

Application number: When the patent applicant filed a patent application in China National Intellectual Property Administration, China National Intellectual Property Administration gave the patent application acceptance notice and patent application number.

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. If a patent is being applied, but the ZL letter is added before the application number (making consumers mistakenly think it is an authorized patent), it is a counterfeit patent and the administrative department for industry and commerce will investigate and deal with it according to law.

2, the composition is different

The patent application number is represented by 12 digits, including the application year number, application category number and application serial number. From left to right, the number 1-4 in the patent application number indicates the year when the patent application was accepted, the number 5 indicates the type of the patent application, and the number 6- 12 (***7) indicates the serial number of the application, indicating the relative order of accepting the patent application.

The patent number is ZL (patent initials)+application number.

3. Different functions

Similar products of other enterprises can be distinguished from their own products to avoid confusion among consumers; Because patents are protected by national laws, no one can copy and sell them without permission.

Advertising function: Consumers usually think that products marked with patent marks or patent numbers are superior to similar traditional products in technical performance and use function, so they will trust the quality of products and expand their market share.

Patent number refers to the number of the patent granted, according to which the description of the patent can be found.
