After filing a trademark application, the Examining attorney at the United States Patent and Trademark office, assigned to your matter, may issue an office action. Office actions inform about issues with an application. They address why an application is being refused or what requirements must be satisfied before a trademark registration is issued.
Office actions most commonly include a refusal based on likelihood of confusion with a prior registered or filed trademark, descriptiveness of a filed mark, surnames as a trademark, amendments to the trademark id, violations of the controlled substances act, incorrect specimens, disclaimer requests, etc.
