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: exclusiveness. Simply put, no unit or individual may regionalize its patent within a certain period of time (within the validity period of patent right) and within a certain area (within the legal jurisdiction) without the permission of the patentee. Regionality means that patent right is a kind of 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: it can distinguish similar products of other enterprises from their own products to avoid confusion among consumers; Warning function: Since patents are protected by national laws, no one may 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.
Legal basis: Article 10 of the Patent Law of People's Republic of China (PRC), the patent application right and patent right can be transferred.
Where a unit or individual in China transfers the right to apply for a patent or the patent right to a foreigner, foreign enterprise or other foreign organization, it shall go through the formalities in accordance with the provisions of relevant laws and administrative regulations.
Where the right to apply for a patent or the patent right is transferred, the parties concerned shall conclude a written contract and register it with the patent administration department of the State Council, which shall make an announcement. The transfer of the right to apply for a patent or the patent right shall take effect from the date of registration.
