Before the patent application is authorized, does the patent applicant have the right to mark the patent application number on its products?

Not allowed, you haven’t obtained the patent yet. Because our application number is consistent with the patent number after authorization, marking the application number on the product will make people mistakenly think that a patent has been obtained. Among the crimes of patent counterfeiting are: marking other people’s proprietary marks or patent numbers on non-patented products or patents. Although the application belongs to you, the application number cannot be marked without authorization.
