eTerminal Disclaimer

The United States Patent and Trademark Office is pleased to announce the release of eTerminal Disclaimer in Patent Center. The new eTerminal Disclaimer provides applicants with many advantages and promotes greater efficiency in the patent examination process. This web-based eTerminal Disclaimer can be filled out completely online through web-screens and no Patent Center fillable forms are required. eTerminal Disclaimers are auto-processed and approved immediately upon submission if the request meets all of the requirements.

Fees must be paid immediately which will then provide users more financial flexibility. A paper terminal disclaimer filing requires a fee but does not guarantee a terminal disclaimer approval. Each eTerminal Disclaimer filed requires a single terminal disclaimer fee, but can include up to 50 "reference applications" and 50 "prior patents."

The electronic Terminal Disclaimer (eTD) can only be used if:

  1. the inventor(s) named as the applicant in the application own(s) 100% of the entire right, title and interest;
  2. the assignee and/or obligated assignee named as the applicant in the application owns 100% of the entire right, title and interest; or
  3. some combination of inventor(s) and partial assignee(s) named as the applicant in the application together own 100% of the entire right, title and interest.

Basic Guidelines for Filing eTerminal Disclaimers:

  • Must be able to access Patent Center as a registered user.
  • Registered eFiler users are strongly advised to transmit their electronic filings sufficiently early in the day to allow time for alternative paper filing when transmission cannot be initiated or correctly completed.
  • Consult the current fee schedule available at for the correct fee amount. The fee required to be paid upon filing a request for eTerminal Disclaimer is: Statutory disclaimer, including terminal disclaimer.
  • In accordance with MPEP 1490 V and 37 CFR 1.321, Terminal Disclaimers (including eTerminal Disclaimers) will only be considered in compliance with the requirements when filed into a PENDING Nonprovisional Utility application (including national stage and reissue) or PENDING Design application (including reissue).  If an eTerminal Disclaimer is filed after payment of the issue fee but before the patent grant date, a request for Certificate of Correction must be filed requesting that the face of the patent be amended to state --This patent is subject to a terminal disclaimer.
  • Requests for terminal disclaimers for plant applications, reexaminations and terminal disclaimers based on a joint research agreement must be filed by paper.
