An Office Action is a formal letter from a USPTO examining attorney explaining why your trademark application cannot proceed as filed. Most refusals can be overcome with the right amendment, evidence, or legal argument — but missing the response deadline can abandon your application.
After you file, a USPTO examining attorney reviews your application against federal trademark law and the USPTO database of registered and pending marks. If problems are found, the USPTO issues an Office Action listing each issue and what you must do to continue prosecution.
Most Office Actions require a response within three months from the issue date, though extensions may be available for a fee. If you do not respond in time, the application may be abandoned. Treat the deadline as firm and plan your response early.
