What is the difference between a minor office action and a major office action?
A minor office action is issued by the examining attorney at the USPTO when the submitted trademark application contains minor errors such as typographical errors or improperly formatted documents.
A major office action is issued by the examining attorney at the USPTO when the submitted trademark application contains major errors, resulting in registration refusals that will require extensive research and legal arguments to overcome. If the examining attorney at the USPTO determines there is a conflict between the trademark you applied for and a trademark that is either registered or pending in the USPTO because the marks are similar in sound, appearance, or meaning, he or she will refuse or reject your mark for likelihood of confusion in the form of a major office action.
