EFS-Web Contingency

The United States Patent and Trademark Office (USPTO) is increasing the availability of its patent electronic filing system, Electronic Filing System - Web (EFS-Web) by providing a new contingency option when the primary portal for EFS-Web is unavailable. Similar to EFS-Web Unregistered, EFS-Web Contingency offers the same user interface and equivalent functionality by permitting users to file new applications, national stage submissions under 35 U.S.C. 371, requests for reexamination, and certain petitions.

Note: Follow-on submissions not permitted in EFS-Web Contingency

Filing follow-on documents and follow-on fee payments to an existing patent application is not permitted via EFS-Web Contingency. When an applicant improperly files a follow-on document as a new application via EFS-Web Contingency (or EFS-Web) and requests the USPTO to move the follow-on document to the appropriate application, a petition under 37 CRF 1.182 accompanied by the petition fee will be required.

Note: Saved Submissions not available in EFS-Web Contingency

Registered e-filers who have uploaded documents to a Saved Submission package in EFS-Web will not be able to retrieve those Saved Submission documents in EFS-Web Backup.
