Registry Consulting is an independent information site, not a law firm, and does not give legal advice. Guides are general information about U.S. trademark law.

Quick answer: An office action is a letter from a USPTO examining attorney listing problems with your trademark application. You usually have three months from the date it issues to respond, with one optional three-month extension for a fee. If you miss the deadline, the application is abandoned.

Many office actions are simple fixes, like clarifying your goods or services. Others, like a likelihood-of-confusion refusal, need a legal argument. Read the title and deadline first.

Types of office actions

TypeWhat it meansWhat to do
Nonfinal office actionThe first time a problem is raisedRespond within 3 months using the USPTO's response form
Final office actionYour last chance during examinationRespond within 3 months; you can also appeal to the Trademark Trial and Appeal Board

Priority actionConfirms a call or email about the problemsRespond within 3 months unless extended

Madrid applications filed under Section 66(a) have a six-month deadline with no extension, according to the USPTO.

Requirements vs. refusals

Requirements are fixable paperwork issues, such as a vague description of goods or a missing disclaimer. Refusals are legal objections to the mark itself, most often that it's likely to be confused with an existing registration or that it merely describes what you sell. Refusals are where an attorney usually earns their fee. Our trademark search guide explains how to spot conflicts before you file.

How to respond, step by step

  1. Find the issue date and deadline at the top of the letter, and note them.
  2. List every requirement and refusal; you must address each one.
  3. For simple requirements, the examining attorney may let you fix them by phone or email.
  4. For refusals, prepare written arguments and any evidence.
  5. File through the USPTO's online response form before the deadline.

If you missed the deadline

The application is abandoned. If the delay was unintentional, you can generally file a petition to revive, which has its own deadline and fee. Check the USPTO's current rules right away.

When to get help

Get an attorney for a likelihood-of-confusion or descriptiveness refusal, or for any final office action. If your domicile is outside the U.S., you must use a U.S.-licensed attorney. See when a trademark attorney is worth it.
