Choosing your ESTTA form

The forms in the Electronic System for Trademark Trial and Appeals (ESTTA) are divided into three main categories:

  1. Request an extension of time to file an opposition
  2. File a new proceeding
  3. File documents in a board proceeding.

Browse the forms in each category below. Select each form to learn when and how to use it.

After you’ve read the information below and prepared to file, go to ESTTA to submit your filing.

Request for extension of time to file an opposition

Prior to registration on the Principal Register, all marks are published  in the Official Gazette of the United States Patent and Trademark Office. The Official Gazette is published weekly and provides notice to all potential opposers. The Official Gazette is available on the USPTO website.

A “potential opposer” may request an extension of time to file an opposition, and must file the request prior to the expiration of the 30-day opposition period. Further extensions of time to oppose must be filed prior to any extension that was previously granted to the potential opposer. If an opposition or extension of time to oppose is not filed within 30 days following the publication date, a mark will proceed to registration or issuance of a notice of allowance, as appropriate.

Marks to be registered on the Supplemental Register are not published prior to registration, and are therefore not subject to opposition. If any party believes it is damaged by the existence of a mark on the Supplemental Register, it may file a petition for cancellation

File a new proceeding

Use these options to file a new notice of opposition, a new petition for cancellation, or an appeal from a final refusal to register. Choose the appropriate filing and enter the serial number of the application to be opposed, the registration number of the registration to be cancelled, or the serial number of the application that is subject to the appeal.

File documents in a Board proceeding

Use these options to file documents (motions, briefs, etc.) in an already existing opposition, cancellation, concurrent use, or appeal proceeding. Choose a “Type of filing” and enter the opposition number (91xxxxxx), cancellation number (92xxxxxx), concurrent use number (94xxxxxx), or application serial number (7xxxxxxx or 8xxxxxxx) to which your filing applies.
