Patents are accepted first and then paid.

Entrust an agency to apply for a patent, first sign a confidentiality agreement, and then sign a contract. The contract stipulates the mode of payment, which generally requires payment first and then written by the agency. After submission, you will get the acceptance notice and payment notice issued by the State Organs Administration Bureau, and you need to pay official fees. If there is any agency fee, it will be supplemented. Then the patent enters the examination period.
