What is the specific meaning of patent document number?

What is the specific meaning of patent document number? There are many patent applications, including application number, WeChat official account, authorization number, etc. What is the serial number of the patent issuance? The document number means the publication, announcement and revision of the patent. Will be published in the patent bulletin and other places. Each such document has a number, which is called the document number. For example, if the specification of an invention patent is published, the document (specification) will be given a number for future reference. What is the specific meaning of patent document number? There will be corresponding numbers in the process of patent application, especially for invention patents. The application process is complicated, and each process gives the corresponding patent number and related document number, application year+patent application type+application serial number, the first two digits indicate the application year number, and the third digit: 1= invention patent application 2= utility model patent application 3= design patent application 8= PCT invention patent application 9= China national phase. The last 5 digits are the application serial number. For example, the application was sent on 20 14-2-26, and the serial number was 20140221010450, and the numbers in it also had specific meanings. The document number represents a document, not a patent. A patent has only one announcement number, but there are many contribution numbers. The patent authorization number refers to the patent announcement number, and the WeChat official account refers to the number given after the invention patent passes the preliminary examination and is announced. WeChat official account does not necessarily authorize, and the announcement number authorizes; ZL begins with an authorization patent number, which proves that it has been authorized. WeChat official account at the beginning of CN indicates that the patent applied for is being published or has been published, and there may be no authorization. Therefore, those who have ZL numbers generally have CN numbers, and those who have CN numbers may not be authorized to have ZL numbers. Finally, it should be noted that the application number does not mean that the product or method is a patent, and some of them have applied but failed to pass the strict examination of the patent office, were rejected or were not authorized in other ways. Therefore, this is not a patent and cannot be a patent number. What is the specific meaning of patent document number? We are here to answer this question for you.
