Preparing Your Patent Application for Electronic Disclaimer Submission

Accessing the Online Disclaimer Portal

  1. Begin by navigating to the official USPTO Patent Center website and securely logging in with your registered user credentials. This digital portal serves as your gateway to various online account management functions, including the eTerminal Disclaimer service.
  2. Once logged in, locate and select the option for 'Existing submissions' either from a dropdown menu or by clicking on the dedicated card under the 'Activities' section. This action initiates the process for submitting a new eTerminal Disclaimer.
  3. Proceed through the web-based screens, entering all necessary application data. The system allows you to add multiple owners, specify their ownership percentages, and list all relevant reference applications and prior patents directly within the online interface.
  4. Carefully review all certification statements presented. You must select and confirm these statements to indicate your eligibility and agreement with the terms. If you are unable to select them, it signifies that your application may not meet the eligibility criteria for an eTerminal Disclaimer.
  5. After completing the online form, you will be prompted to make the required fee payment. This step is mandatory, and the system processes the payment immediately.
  6. Upon successful submission and payment, the eTerminal Disclaimer is auto-processed. If all requirements are fulfilled, it receives immediate approval, and you will receive an acknowledgment receipt and grant letter.

Streamlining Patent Term Adjustments Digitally

Navigating Unexpected Challenges During Submission

⚠️ Unable to proceed beyond the eTerminal Disclaimer initiation page in Patent Center.

Cause: System-related issue or specific configuration challenge within Patent Center preventing advancement.

Solution: We understand encountering technical difficulties can be frustrating. If you face this, the recommended workaround is to file your terminal disclaimer using the appropriate paper form (such as AIA/25, AIA/26, AIA/63, SB/25a, or SB/26a) as a follow-on filing. Remember to include the necessary fee with your paper submission.

⚠️ My e-signature exceeds 15 characters, and I cannot submit via Patent Center.

Cause: A known limitation within the Patent Center system restricts e-signature length for this particular filing type.

Solution: We recognize this can be an unexpected hurdle. The quickest path forward is to utilize the EFS-Web system to file your eTerminal Disclaimer. This alternative platform accommodates longer e-signatures without issue.

⚠️ My unsubmitted eTerminal Disclaimer request was lost.

Cause: Inactivity in the Patent Center digital portal.

Solution: To protect your information, Patent Center sessions automatically time out after 30 minutes of inactivity. If an eTerminal Disclaimer request remains unsubmitted after one hour of inactivity, it will be lost. We recommend saving your progress frequently and submitting your forms promptly to avoid losing your work.

Answers to Key Questions About Your Disclaimer Filing

Q: What exactly is an eTerminal Disclaimer?

An eTerminal Disclaimer is an electronic filing service provided by the USPTO. It allows patent applicants to disclaim a portion of a patent's term to ensure that all similar patents owned by the same entity expire on the same date, primarily used to overcome non-statutory double patenting rejections.

Q: Who is eligible to file using the eTerminal Disclaimer system?

You are eligible if you are a registered eFiler with Patent Center access, and the applicant (inventor(s) or assignee(s)) holds 100% of the entire right, title, and interest in the application. Partial assignees and inventors combined must also hold 100% interest.

Q: What are the advantages of using the eTerminal Disclaimer over a paper filing?

The eTerminal Disclaimer offers immediate processing and approval upon successful submission, greater control over filing times, and financial flexibility with immediate fee payment. Unlike paper filings, it guarantees approval if all requirements are met, and streamlines the process through its web-based interface.

Q: What should I do if my e-signature is too long for the Patent Center system?

If your e-signature contains more than 15 characters, you will encounter an error in Patent Center. The USPTO advises using the EFS-Web system as an alternative to successfully submit your eTerminal Disclaimer in this scenario.

Q: Can I submit an eTerminal Disclaimer for any patent application type?

eTerminal Disclaimers are specifically accepted for pending Nonprovisional Utility applications (including national stage and reissue) or pending Design applications (including reissue). They are not typically used for other application types.
