The patent certificate is mentioned in the manufacturer's introduction. Do I have to list the license number?

The essence of patent system is to exchange publicity for protection. It has been published by the patent office and is not afraid of being imitated. The more he imitates, the more useful your invention will be. It will open the market for you. You just need to pay close attention, find good evidence, wait until the certificate is confirmed, and then kill the sheep when it is fat.
