The payment information is filled in incorrectly and the payment method is incorrect.
1. Wrong filling of payment information: When paying patent fees, patent applicants will fill in the wrong patent number, applicant information or payment amount, etc., resulting in the patent office being unable to confirm whether the fees have been paid successfully.
2. Incorrect payment method: The patent applicant used a payment method that is not recognized by the Patent Office, such as using an unauthorized third-party agency for payment, or using an illegal payment method. .
