Final Office Action Law and Legal Definition

In the U.S. Patent law, an office action refers to a document written by a patent examiner after examining a patent application. An office action can be final or non-final. A final office action refers to a patent examiner’s determination based on a patent application. The patent examiner determines that an application is not allowable. Based on such determination, the applicant may file a continuation application, appeal the decision, or request continued prosecution. Reply to a final rejection should include cancellation or appeal from the rejection of each rejected claim.
