What is the abbreviation of patent?

The patent application number is the notification of patent application acceptance and the patent application number given by the Patent Office as the receipt when the patent applicant submits a patent application to China National Intellectual Property Administration. The patent number is the patent number formed by adding the English beginning to the previously received application number after the patent application is authorized.

The patent number is different from ZL (patent initials)+application number. If there is a patent in the application, 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. So how to explain the good abbreviation of patent? The following details are introduced:

The prefix of the patent number used by China is ZL, so don't mistake it for CN. Patent abbreviations in other countries are as follows: DE? Germany? EP？ European Patent Office, California? Canada, ES? Spain, France? France, GR? Greece, UA? Ukraine, African Union? Australia, CL? Chile, JP? Japan, KR? Korea, TH? Thailand, NL? Holland, SE? Sweden, CH? Swiss, AP, African regional industrial property organization? And HK? Hong kong? Taiwan Province province.

Patent abbreviations are generally used to distinguish the types of patents in different countries, and give simple and clear patent number specifications, so as to distinguish similar products of other enterprises from their own products and avoid confusion among consumers; Because patents are protected by national laws, no one can copy and sell them without permission.
