Why does a patent have several announcement numbers?

What is the relationship between patent number, application number, WeChat official account and announcement number? Knowing the meanings of application number, patent number, WeChat official account number and announcement number, straightening out the relationship between them and determining the legal status of patents can enable us to effectively use patent literature knowledge, guide us to use patent literature, apply for patents and protect our intellectual property rights.

When we apply for a patent, we need to consult the patent literature in this technical field and understand the existing technical scheme. When inquiring about patents, we will encounter various expressions citing patent documents, such as patent application number, patent publication number, patent number and so on. For the same patent, there will be different literature types (such as specifications) and different patent-related numbers and dates. These seem to be very puzzling. If we understand the relationship between them, their significance and the legal status of the patents they represent, we can better grasp them, so as to understand the different types of patents, the application process of patents and the current legal status of patents.

When filing a patent application, the patent application number is obtained. In the process of patent examination, different patent documents and corresponding submission numbers will be produced, which are divided into publication specification, patent specification and patent certificate in turn. The corresponding submission numbers are publication number, announcement number and patent number, and the corresponding dates are patent announcement date and authorization announcement date.

The patent contribution number is represented by 9 Arabic numerals, including the application type number and serial number.

The order of arrangement should be: country code CN, patent contribution number and patent document type identification code. If necessary, you can use 1 single-byte spaces between the country code CN and the patent contribution number, the patent contribution number and the patent document type identification code respectively.
