Welcome to ESTTA
Using ESTTA, you can make TTAB submissions online. While many sections of the required forms may appear straightforward and easy to fill out, you are strongly advised to read the instructions for EACH section prior to any data entry. If you fail to follow the instructions, you might fill out sections of the forms incorrectly, thereby jeopardizing your legal rights.

PLAN AHEAD. Because unexpected problems can occur, you should keep filing deadlines in mind and allow plenty of time to resolve any issue which might arise. The Board will provide general assistance to ESTTA filers (see contact information below), but we cannot guarantee that any problem will be resolved prior to a deadline. Except when filing extensions of time to oppose or oppositions to Madrid Protocol applications (see below), ESTTA filing is optional. If ESTTA filing is not possible prior to a deadline for any reason, parties should submit their filings in paper.

Filing Date. Eastern Time controls the filing date. ESTTA filings are time-stamped with the official filing date when the ESTTA filing, including any required fee is received on the USPTO server. The time the transmission began is not a factor we consider when we assign the filing date. The official filing date and time can be found on the confirmation web screen and in your e-mail confirmation.

Fees. If there is a fee for the filing, you must pay by credit card (MasterCard, Visa, American Express or Discover), Electronic Funds Transfer, or through an existing USPTO deposit account.

  • Highlighted terms are linked to relevant instructions or help screens, which will open in a new window.
  • You must complete all fields labeled with the required field symbol; you should complete all other relevant fields if you know the information.
  • Do not use your browser's "back" and "forward" buttons to navigate. Use only the navigation buttons and links on the ESTTA screens.
  • After completing all required fields, you will be prompted to validate and sign your submission. The data appearing on this screen will be submitted to the TTAB. If necessary, navigate back to the proper field to correct the information prior to transmitting the form.
  • Upon transmission, the form will be assigned an ESTTA tracking number that will be displayed on the next screen.
  • Once you submit a request electronically, the office will immediately provide you with an e-mail acknowledgment of receipt. Print a copy of this screen for your records. Please contact the Office within 24 hours of transmission (or by the next business day) if you do not receive this acknowledgment.
  • Once you file a paper electronically, you may not withdraw the submission from the file, unless the request fails to satisfy the minimum filing requirements. No fee paid will be refunded unless paid by mistake or in excess of the amount required.

Oppositions to extensions of protection under the Madrid Protocol (or requests for extensions of time to oppose) must be filed electronically using ESTTA. If you are a first-time user, we urge you to plan ahead, and to submit your notice of opposition well prior to the deadline in case you encounter problems. The Board will not extend the time to oppose other than as specifically set out in the Trademark Rules.

The USPTO published a notice of final rulemaking in the Federal Register on August 1, 2007, at 72 Fed. Reg. 42242. By this notice, various rules governing Trademark Trial and Appeal Board inter partes proceedings are amended. As the Board adapts the ESTTA system to accommodate the amended rules, users are urged to review the rules to ensure that attachments to ESTTA submissions meet the requirements of the amended rules. In addition, users must note any warnings posted on ESTTA screens or filing forms that may temporarily restrict their use to cases commenced prior to November 1, 2007, the effective date of many of the amended rules.

You can reach the TTAB at 571-272-8500. For technical assistance with ESTTA filings, you may send email to We will respond to your e-mail inquiry within 2 business days. In addition to the problem description, please include your telephone number and ESTTA tracking number (if any) in your email, so we can assess the problem and talk to you directly, if necessary.

Inquiries regarding non-technical matters, including general procedural questions or specific inquiries regarding a particular Board proceeding should be directed to the interlocutory attorney or paralegal assigned to the case, if known. If you do not know the telephone number of the interlocutory attorney or paralegal assigned to your proceeding, or if you are not involved in a proceeding before the Board, please telephone us at 571-272-8500 for assistance during Eastern time zone business hours.

NO submissions for any Board proceeding will be accepted via the mail box. All submissions should be filed using the appropriate ESTTA form or by mail.

The information collected on these forms allows the TTAB to determine whether a party is entitled to registration of a mark. Responses to the requests for information are required to obtain the requested action. All information collected will be made public. Gathering and providing the information will require an estimated 10 to 45 minutes, depending on the form you choose. Please direct comments on the time needed to complete this form, and/or suggestions for reducing this burden to the Chief Information Officer, U.S. Patent and Trademark Office, U.S. Department of Commerce, Washington, DC 20231. Please note that the TTAB may not conduct or sponsor a collection of information using a form that does not display a valid OMB control number.
