(a) Patent fees and charges payable to the United States Patent and Trademark Office are required to be paid in advance; that is, at the time of requesting any action by the Office for which a fee or charge is payable with the exception that under § 1.53 applications for patent may be assigned a filing date without payment of the basic filing fee.
(b) All fees paid to the United States Patent and Trademark Office must be itemized in each individual application, patent, or other proceeding in such a manner that it is clear for which purpose the fees are paid. The Office may return fees that are not itemized as required by this paragraph. The provisions of § 1.5(a) do not apply to the resubmission of fees returned pursuant to this paragraph.

(a) All payments of money required for United States Patent and Trademark Office fees, including fees for the processing of international applications (§ 1.445), 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. If sent in any other form, the Office may delay or cancel the credit until collection is made. Checks and money orders must be made payable to the Director of the United States Patent and Trademark Office. (Checks made payable to the Commissioner of Patents and Trademarks will continue to be accepted.) Payments from foreign countries must be payable and immediately negotiable in the United States for the full amount of the fee required. Money sent to the Office by mail will be at the risk of the sender, and letters containing money should be registered with the United States Postal Service.
(b) Payments of money required for United States Patent and Trademark Office fees may also be made by credit card, except for replenishing a deposit account. Payment of a fee by credit card must specify the amount to be charged to the credit card and such other information as is necessary to process the charge, and is subject to collection of the fee. The Office will not accept a general authorization to charge fees to a credit card. If credit card information is provided on a form or document other than a form provided by the Office for the payment of fees by credit card, the Office will not be liable if the credit card number becomes public knowledge.
(c) A fee transmittal letter may be signed by a juristic applicant or patent owner.

(a) The Director may refund any fee paid by mistake or in excess of that required. A change of purpose after the payment of a fee, such as when a party desires to withdraw a patent filing for which the fee was paid, including an application, an appeal, or a request for an oral hearing, will not entitle a party to a refund of such fee. The Office will not refund amounts of twenty-five dollars or less unless a refund is specifically requested, and will not notify the payor of such amounts. If a party paying a fee or requesting a refund does not provide the banking information necessary for making refunds by electronic funds transfer (31 U.S.C. 3332 and 31 CFR part 208), or instruct the Office that refunds are to be credited to a deposit account, the Director may require such information, or use the banking information on the payment instrument to make a refund. Any refund of a fee paid by credit card will be by a credit to the credit card account to which the fee was charged.
(b) Any request for refund must be filed within two years from the date the fee was paid, except as otherwise provided in this paragraph or in § 1.28(a). If the Office charges a deposit account by an amount other than an amount specifically indicated in an authorization (§ 1.25(b)), any request for refund based upon such charge must be filed within two years from the date of the deposit account statement indicating such charge, and include a copy of that deposit account statement. The time periods set forth in this paragraph are not extendable.
(c) If the Director decides not to institute a reexamination proceeding in response to a request for reexamination or supplemental examination, fees paid with the request for reexamination or supplemental examination will be refunded or returned in accordance with paragraphs (c)(1) through (c)(3) of this section. The reexamination requester or the patent owner who requested a supplemental examination proceeding, as appropriate, should indicate the form in which any refund should be made ( e.g., by check, electronic funds transfer, credit to a deposit account). Generally, refunds will be issued in the form that the original payment was provided.

(1) For an ex parte reexamination request, the ex parte reexamination filing fee paid by the reexamination requester, less the fee set forth in § 1.20(c)(7), will be refunded to the requester if the Director decides not to institute an ex parte reexamination proceeding.
(2) For an inter partes reexamination request, a refund of $7,970 will be made to the reexamination requester if the Director decides not to institute an inter partes reexamination proceeding.
(3) For a supplemental examination request, the fee for reexamination ordered as a result of supplemental examination, as set forth in § 1.20(k)(2), will be returned to the patent owner who requested the supplemental examination proceeding if the Director decides not to institute a reexamination proceeding.

(a) For the convenience of attorneys, and the general public in paying any fees due, in ordering services offered by the Office, copies of records, etc., deposit accounts may be established in the Patent and Trademark Office upon payment of the fee for establishing a deposit account § 1.21(b)(1). A minimum deposit of $1,000 is required for paying any fee due or in ordering any services offered by the Office. However, a minimum deposit of $300 may be paid to establish a restricted subscription deposit account used exclusively for subscription order of patent copies as issued. At the end of each month, a deposit account statement will be rendered. A remittance must be made promptly upon receipt of the statement to cover the value of items or services charged to the account and thus restore the account to its established normal deposit value. An amount sufficient to cover all fees, services, copies, etc., requested must always be on deposit. Charges to accounts with insufficient funds will not be accepted. A service charge (§ 1.21(b)(2)) will be assessed for each month that the balance at the end of the month is below $1,000. For restricted subscription deposit accounts, a service charge (§ 1.21(b)(3)) will be assessed for each month that the balance at the end of the month is below $300.
(b) Filing, issue, appeal, international-type search report, international application processing, international design application fees, petition, and post-issuance fees may be charged against these accounts if sufficient funds are on deposit to cover such fees. A general authorization to charge all fees, or only certain fees, set forth in §§ 1.16 through 1.18 to a deposit account containing sufficient funds may be filed in an individual application, either for the entire pendency of the application or with a particular paper filed. A general authorization to charge fees in an international design application set forth in § 1.1031 will only be effective for the transmittal fee (§ 1.1031(a)). An authorization to charge fees under § 1.16 in an international application entering the national stage under 35 U.S.C. 371 will be treated as an authorization to charge fees under § 1.492. An authorization to charge fees set forth in § 1.18 to a deposit account is subject to the provisions of § 1.311(b). An authorization to charge to a deposit account the fee for a request for reexamination pursuant to § 1.510 or 1.913 and any other fees required in a reexamination proceeding in a patent may also be filed with the request for reexamination, and an authorization to charge to a deposit account the fee for a request for supplemental examination pursuant to § 1.610 and any other fees required in a supplemental examination proceeding in a patent may also be filed with the request for supplemental examination. An authorization to charge a fee to a deposit account will not be considered payment of the fee on the date the authorization to charge the fee is effective as to the particular fee to be charged unless sufficient funds are present in the account to cover the fee.
(c) A deposit account holder may replenish the deposit account by submitting a payment to the United States Patent and Trademark Office. A payment to replenish a deposit account must be submitted by one of the methods set forth in paragraphs (c)(1), (c)(2), (c)(3), or (c)(4) of this section.

(1) A payment to replenish a deposit account may be submitted by electronic funds transfer through the Federal Reserve Fedwire System, which requires that the following information be provided to the deposit account holder’s bank or financial institution:

(i) Name of the Bank, which is Treas NYC (Treasury New York City);
(ii) Bank Routing Code, which is 021030004;
(iii) United States Patent and Trademark Office account number with the Department of the Treasury, which is 13100001; and
(iv) The deposit account holder’s company name and deposit account number.

(2) A payment to replenish a deposit account may be submitted by electronic funds transfer over the Office’s Internet website (www.uspto.gov).
(3) A payment to replenish a deposit account may be addressed to: Director of the United States Patent and Trademark Office, Attn: Deposit Accounts, 2051 Jamieson Avenue, Suite 300, Alexandria, Virginia 22314.
