it is not necessary to mark the patent number. If the mark is incorrect, the department in charge of patent work may require it to make corrections within a time limit. Unless it is marked incorrectly, which constitutes an act of impersonating a patent, it will involve punishment.
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 only the application has not been authorized, it must be marked as "patent application".
