No patent number is indicated. How much does it cost?

1. Mark the categories of patent rights in Chinese, such as China invention patent, China utility model patent and China design patent, as long as they are clearly marked.

2. There is no need to mark the patent number. If the mark is incorrect, the administrative department for patent work may require it to make corrections within a time limit. Unless the label is wrong, which constitutes an act of impersonating a patent, it will involve punishment.

3. When marking a patent, it is necessary to confirm the legal status of the patent, and it must be in an authorized state before it can be marked as a patent. If the application is not authorized, it must be marked as a patent application.
