You can check the telephone numbers and addresses of patent agencies in China National Intellectual Property Administration.
If not, you can also pay the fee directly to China National Intellectual Property Administration. But you need to indicate the patent application number and the related information of the fee category on the money order. If you fill in the wrong information, you may not be able to hand it in or hand it over to others, hehe. The biggest drawback of this situation is that it delays your payment time. Patent fees are paid in time, and there is no way to recover some delayed time. Therefore, if there is no local agency, it is best to find an agency to help pay and catch some.
Reminder: When you entrust an agency to pay the corresponding expenses, you need to ask the agency for the relevant expense invoice issued by China National Intellectual Property Administration to ensure that your expenses are paid immediately and accurately.
