The difference between patent number and application number:
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.
Characteristics of patent number:
Exclusive, the meaning is very simple, that is, within a certain period of time (within the validity period of the patent right) and within the region (within the legal jurisdiction), no unit or individual may exploit its patent without the permission of the patentee.
Regionality, regionality means that patent right is a right with limited geographical scope, which is only valid within the legal jurisdiction.
Timeliness means that a patent is only valid within the time limit prescribed by law. After the expiration of the effective protection period of the patent right, the patent right enjoyed by the patentee will be automatically lost and generally cannot be renewed.
The role of patent number:
Differentiation function: you can distinguish similar products of other enterprises from your own products to avoid confusion among consumers;
Warning function: Since patents are protected by national laws, no one may copy or 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.
