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 is not necessarily authorized, but the announcement number is authorized.
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. The document number represents a document, not a patent. A patent has only one announcement number, but there are many contribution numbers.
I hope the answer will help you.
