How to check the patent number arrears? Only the patent number was found on the patent website, but no patent was found. How much should I pay?

Hello, under normal circumstances, you can work out how much money you have to pay. You can go to China Patent Inquiry System to inquire about the documents issued by the State Knowledge Bureau, which are recorded in the paper notice issued by them. Really not good. You can call the National Knowledge Bureau to get a more accurate understanding of the payment situation.
