MPEP § 502.01

*****
The date of receipt accorded to any correspondence permitted to be sent by facsimile transmission, including a continued prosecution application (CPA) filed under 37 CFR 1.53(d), (available for design applications only) is the date the complete transmission is received by an Office facsimile unit, unless the transmission is completed on a Saturday, Sunday, or Federal holiday within the District of Columbia. Correspondence for which transmission was completed on a Saturday, Sunday, or Federal holiday within the District of Columbia, will be accorded a receipt date of the next succeeding day which is not a Saturday, Sunday, or Federal holiday within the District of Columbia. For example, a facsimile transmission to the Office from California starting on a Friday at 8:45 p.m. Pacific time and taking 20 minutes, would be completed at 9:05 p.m. Pacific time. The complete transmission would be received in the Office around 12:05 a.m. Eastern time on Saturday. The receipt date accorded to the correspondence is the date of the following business day, which in this case, would be Monday (assuming that Monday was not a Federal holiday within the District of Columbia). Note, however, that if the Certificate of Transmission is available (for documents not proscribed by 37 CFR 1.8(a)(2) ), then the above facsimile may be considered timely filed on Friday if it contains a Certificate of Transmission and is in compliance with 37 CFR 1.8(a)(1)(i)(B) and (ii).
37 CFR 1.6(d) specifies the types of correspondence which may be transmitted by facsimile. These would include CPAs filed under 37 CFR 1.53(d) (available for design applications only), amendments, declarations, petitions, information disclosure statements (IDS), terminal disclaimers, notices of appeal and appeal briefs, requests for continued examination (RCEs) under 37 CFR 1.114, assignment documents, issue fee transmittals and authorizations to charge deposit accounts. The situations where transmissions by facsimile are prohibited are identified in 37 CFR 1.6(d)(2)-(7). Prohibitions cover situations where originals are required as specified in 37 CFR 1.4(f), and situations where accepting a facsimile transmission would be unduly burdensome on the Office. As a courtesy, the Office will attempt to notify senders whenever correspondence is sent to the Office by facsimile transmission that falls within one of the prohibitions. Senders are cautioned against submitting correspondence by facsimile transmission which is not permitted under 37 CFR 1.6(d) since such correspondence will not be accorded a receipt date.
An applicant filing a CPA (available for a design application only) by facsimile transmission must include an authorization to charge the basic filing fee to a deposit account or to a credit card, or the application will be treated under 37 CFR 1.53(f) as having been filed without the basic filing fee (as fees cannot otherwise be transmitted by facsimile).
There is a special receipt procedure for filing a CPA by fax, whereby the Office will fax back a receipt of the CPA filing if applicant submits the Office receipt form along with the CPA filing.

37 CFR 1.6(f) provides for the situation in which the Office has no evidence of receipt of a CPA transmitted to the Office by facsimile transmission. 37 CFR 1.6(f) requires a petition be filed requesting that the CPA be accorded a filing date as of the date the CPA is shown to have been transmitted to and received in the Office. The showing must include, inter alia, a copy of the sending unit’s report confirming transmission of the application or evidence that came into being after the complete transmission of the application and within one business day of the complete transmission of the application.
All patent application related correspondence transmitted by facsimile must be directed to the central facsimile number, with a few exceptions below. The central facsimile number is (571) 273-8300. Replies to Office actions including after-final amendments that are transmitted by facsimile must be directed to the central facsimile number. Correspondence such as draft proposed amendments for interviews may continue to be transmitted by facsimile to the Technology Centers (TCs) and should be made of record as part of the interview summary record. See MPEP § 713.04. Office personnel should not use their personal facsimile numbers for official application related correspondence. Office personnel that inadvertently receive official application related correspondence on a personal facsimile number must either route (do not forward) the correspondence to the official central facsimile number or they may, with applicant’s (or applicant’s representative) permission, make the facsimile amendment part of an examiner’s amendment.
For each Office location listed below, only the particular type of correspondence indicated may be transmitted to the specific facsimile number at that Office location. All other types of facsimile transmitted correspondence must be sent to the central facsimile number ((571) 273-8300).
Note: An international application for patent or a copy of the international application and the basic national fee necessary to enter national stage, as specified in 37 CFR 1.495(b), may not be submitted by facsimile. See 37 CFR 1.6(d)(3) (referencing 37 CFR 1.8(a)(2)(i)(D) and (F) ). Subsequent correspondence may be transmitted by facsimile in an application before the U.S. Receiving Office, the U.S. International Searching Authority, or the U.S. International Preliminary Examining Authority, but it will not receive the benefit of any certificate of transmission (or mailing). See 37 CFR 1.8(a)(2)(i)(E). Correspondence subsequent to filing in an international application before the U.S. Receiving Office, the U.S. International Searching Authority, or the U.S. International Preliminary Examining Authority may be submitted by facsimile to PCT Operations via the USPTO central facsimile number ((571) 273-8300). Correspondence filed during the national stage, subsequent to entry, is handled in the same manner as a U.S. national application.
Note: Although submission of drawings by facsimile may reduce the quality of the drawings, the Office will generally print the drawings as received.
Office of Data Management telephone numbers to check on receipt of payment: (571) 272-4200 or 1-888-786-0101.
Note: The EBC may also be reached by email at: ebc@uspto.gov. EBC telephone number for customer service and assistance: 866-217-9197.
Note: Only documents with an identified patent application or patent number, a single cover sheet to record a single type of transaction, and the fee paid by an authorization to charge a USPTO deposit account or credit card may be submitted via facsimile. Customers may submit documents directly into the automated Patent and Trademark Assignment System and receive the resulting recordation notice at their facsimile machine. (Assignment documents submitted through the Electronic Patent Assignment System also permit the recordation notice to be faxed to customers.) Credit card payments to record assignment documents are acceptable, and use of the Credit Card form (PTO-2038) is required for the credit card information to be separated from the assignment records.
Assignment Recordation Branch telephone number for assistance: (571) 272-3350.
Note: Correspondence related to reexamination proceedings will be separately scanned in the CRU.
CRU telephone number for customer service and inquiries: (571) 272-7705.
Note: Correspondence to be filed in a patent application subject to a secrecy order under 37 CFR 5.1 to 5.5 and directly related to the secrecy order content of the application may not be transmitted via facsimile. See 37 CFR 1.6(d)(6).
Note: All other types of petitions must be directed to the central facsimile number (571) 273-8300, with the exception of a request for a retroactive filing license, which should be directed to (571) 270-9959. Petitions sent to the central facsimile number should be marked "Special Processing Submission."
As set forth in 37 CFR 1.6(d), facsimile transmissions are not permitted and, if submitted, will not be accorded a date of receipt in the following situations:
Applicants are reminded that the facsimile process may reduce the quality of the drawings, and the Office will generally print the drawings as received.
