How can a maintenance fee and any necessary surcharge be made?
The method of payment for the maintenance fee and any necessary surcharge shall be made in U.S. dollars and in the form of a cashier’s or certified check, Treasury note, national bank notes, or United States Postal Service money order as provided in 37 CFR 1.23(a).
If the maintenance fee and any necessary surcharge is sent in any other form, the Office may delay or cancel the credit until collection is made. For example, a personal or other uncertified check drawn on a U.S. bank that is not immediately negotiable, e.g., because it lacks a signature or due to insufficient funds, will not constitute payment of a maintenance fee and/or surcharge.
The maintenance fee can be charged to a credit card as set forth in 37 CFR 1.23(b), but credit for the payment is subject to actual receipt of the fee by the Office.
The answer to this question can be found in chapter 2500 of the MPEP. This chapter covers Maintenance Fees.
