What is the “Reasons Document” in Supplemental Examination?

This page is an FAQ based on guidance from the Manual of Patent Examining Procedure. It is provided as guidance, with links to the ground truth sources. This is information only: it is not legal advice.

The “Reasons Document,” officially called the “Reasons for Substantial New Question of Patentability Determination,” is a document that accompanies the Supplemental Examination Certificate. It provides a detailed explanation of why each item of information submitted in a supplemental examination request does or does not raise a substantial new question of patentability (SNQ).

The MPEP states: This document will explain, for each item of information, why each item does or does not raise a SNQ. The Reasons Document is crucial for understanding the USPTO’s decision regarding the supplemental examination request.
