Patent application fees and other fees can be paid directly to the Patent Office Charge Office or Patent Agency, or remitted through banks or post offices. At present, banks use electronic transfer and post offices use electronic remittance. When the payer pays patent fees through the post office or bank, the correct application number or patent number should be written on the money order, and the abbreviation should be used for the name of the fee paid. The remitter should ask the bank or post office staff to enter the above payment information in the remittance postscript. If the remittance is made through the post office, the remitter should also ask the post office staff to enter the complete mailing address, including postal code.
