The Trademark Trial and Appeal Board (TTAB) is pleased to present the Electronic System for Trademark Trials and Appeals (ESTTA).

Using ESTTA, you can complete and submit forms to the TTAB over the Internet, making an official filing online, or print out the completed form for mailing to the TTAB. ESTTA gives step-by-step instructions for properly completing a form. While the different sections of the forms may appear straightforward and easy to fill out, you are strongly advised to read the instructions for EACH section prior to completing it. Failure to follow the instructions may cause you to fill out sections of the form incorrectly, jeopardizing your legal rights.

  • Eastern Time controls the filing date. All forms filed via ESTTA are stamped with Eastern Time when received on the USPTO server. If a fee is required, the time stamp is applied when the payment process is completed and the receipt screen is displayed. Otherwise, the time stamp is applied at the time of receipt. The time stamp applied by the ESTTA server is the official time the USPTO received the form.
  • NOTE: The time the transmission began is not a factor considered when assigning the filing date. The official filing date and time can be found on the confirmation web screen and in your e-mail confirmation.

  • If there is a fee for this filing, you must pay by credit card (MasterCard, Visa, American Express or Discover) OR through an existing USPTO deposit account.

  • ESTTA works only if you use Netscape Navigator [Version 4.0 or later] or Microsoft Internet Explorer [Version 4.0 or later]. ESTTA utilizes Javascript, and the file upload feature supported by these browser versions.

    NOTE: Internet Explorer on the Macintosh platform will NOT permit a proper image attachment.

  • You must use Internet Explorer version 5 or Netscape in order to use the payment server with the Macintosh platform. Images created on a Macintosh using Adobe Photoshop or Illustrator must be properly saved with appended file extensions .gif or .jpg for use on a Windows system. We cannot open image files that are not properly saved prior to attachment. Also, an Internet Explorer window that sits behind a Microsoft Proxy Server will NOT connect properly. However, if you upgrade to Internet Explorer to 5.01 or higher the site will work properly.

    For general information about filing electronically, please telephone us at, 703-308-9330, ext.181 or e-mail your question(s) to If you need help in resolving technical problems, you can e-mail us at We will respond to your e-mail inquiry within 2 business days.

    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 chosen. Please direct comments on the time needed to complete this form, and/or suggestions for reducing this burden to the U.S. Patent and Trademark Office; Attn: Chief Information Officer; P. O. Box 1450; Alexandria, VA 22313-1450. 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.
