The United States Patent and Trademark Office (USPTO) makes every effort to have the Electronic Filing System (EFS-Web) and Patent Center available 24 hours a day, 7 days a week. Sometimes, the website is unavailable for routine maintenance or is unexpectedly inaccessible. In such cases, the USPTO makes every attempt to restore service as soon as possible.
If your deadline is today and the document cannot be filed via EFS-Web or Patent Center due to an outage, you must use an alternative method of filing (explained below) to ensure that the document is timely received by the USPTO. A deadline that falls on a Saturday, Sunday, or federal holiday within the District of Columbia extends the due date to the next succeeding day that is not a Saturday, Sunday, or federal holiday. 37 CFR 1.7 See the MPEP.

Alternative methods of filing for EFS-Web, EFS-Web Contingency, and Patent Center
In the event that EFS-Web, EFS-Web Contingency, and Patent Center are unavailable, applicants may file new patent applications, new international design applications and documents, and fees for national stage entry under 35 U.S.C. 371 via Priority Mail Express from the United States Postal Service (USPS) in accordance with 37 CFR 1.10.
Applicants may file other documents or fee payments by any of the following ways:
Facsimile transmission to the USPTO Central Facsimile (571) 273-8300
First-Class Mail with a certificate of mailing in accordance with 37 CFR 1.8
- Priority Mail Express from the United States Postal Service (USPS) in accordance with 37 CFR 1.10.
Please note that filing of a new international (PCT) application or a new application under 35 USC 111(a), except reissue, design or plant applications, other than by the USPTO’s electronic filing system requires payment of the non-electronic filing fee (37 CFR 1.16(t) and 1.445(a)(1)(ii)) in addition to the other required fees. The non-electronic filing fee is $400 ($200 for small and micro entities). Also please note that an international design application filed in paper may be subject to additional WIPO publication fees.
New patent applications, new international design applications, copies of the international (PCT) application and basic national fee necessary to enter the national stage under 35 U.S.C. 371, and documents that are required to establish the filing date of an application (e.g.: a missing drawing figure or page of the specification) cannot be submitted by facsimile transmission, and certificate of mailing procedures under 37 CFR 1.8 do not apply to these documents. Patent correspondence, including new patent applications, new international design applications, and documents or fee payments, cannot be submitted via email.
If you have a deadline for filing an AIA trial petition filing and/or other associated documents in a pending AIA case and you cannot file electronically via PTAB E2E, you must use an alternative filing method. Specifically, AIA trial petitions and/or other associated documents may be served on opposing counsel via email. The Board should be notified of the service by email copying opposing counsel: Trials@uspto.gov. The email notification to the Board should NOT include attachments.
Notification to the Board of petitions served via email must include:
- name of point of contact;
- email address of point of contact;
- patent number to which the petition corresponds (or application number in the case of a derivation proceeding);
- application number of the patent;
- petitioner's application number (in the case of a derivation proceeding);
- number of claims challenged;
- type of trial proceeding;
- power of attorney; and
- fee, e.g., a deposit account authorization.
In addition, if a petition or document is served via email or other means, it must be followed by a In addition, if a petition or document is served via email or other means, it must be followed by a later-filed motion requesting acceptance of the submission once PTAB E2E is available. The petition or document will be accorded the date on the certificate of service as the identified filing date. 37 C.F.R. § 42.6(b). It is important to note that a petition will not be accorded a filing date unless it is accompanied by a payment of the appropriate fees (e.g., a deposit account authorization).
If PTAB E2E is down during normal business hours, a party may contact the Board and request a one-day extension of time for due dates that are set by rule or orders of the Board. 37 C.F.R. § 42.5. In the unlikely event that an administrative patent judge is not available to rule on the extension, the Board may grant an extension the day after the paper is due. However, no extensions of time will be granted for any statutory time period.
In the event that you are unable to submit payment online using Financial Manager via EFS-Web or Patent Center, you will find several fee related documents linked here which may be submitted using one of the methods described above. A complete list of fee related documents can be found on the Patent forms page.
- Fee Transmittal (PTO/SB/17)
- Credit Card Payment Form (PTO-2038) (Do not submit this form via EFS-Web or Patent Center)
Please be aware that certain application fees must be paid on the same date as the filing of an application. Failure to pay these fees on the same date as the filing of an application will result in a surcharge for late payment. For details regarding these fees, please reference MPEP 607 I.
