First Office Action Law and Legal Definition

In relation to Patent law, a first office action is the reply of a patent examiner. This is an initial reply of the patent examiner to a patent application. If the first report of the patent examiner rejects all or most of the claims in the application, then it is termed as a shotgun rejection. The applicant should reply or respond by answering to the examiner’s reasons for rejection by amending the claims or both in order to avoid abandoning the prosecution.
