What do you mean by the level of patents and the number of patents? What is the relationship between them?

There are only three kinds of domestic patents: invention, utility model and appearance. There should be no division of patent levels. Maybe I know too little. The number of patents is literally a simple list. The number of patent applications, one application and authorization, is 1, and the number of patents is two.

I don't know what you want to ask

The invention patent is actually examined, and the appearance and utility model are only formal examinations. In a sense, invention patents are more authoritative than utility models.

From the enterprise's point of view, the more invention patents owned and authorized, the higher the R&D level. This is also related to quantity.
