Any seasoned patent practitioner has undoubtedly been in this situation before: a non-final rejection comes to your inbox, and while reviewing, you’re beside yourself how the Examiner arrived at § 101, § 102, § 103, and § 112 rejections of your pristine, unassailably allowable application. Before tearing your hair out in frustration, and hopefully before this happens again, the USPTO transparently provides insights into how an Examiner may be getting to their reasoning for rejecting your application. Prior to diving into the Manual of Patent Examining Procedure (“M.P.E.P.”), the cited case law, or even the cited art relied on by the Examiner in the rejection, take a minute and make your way to the USPTO Examiner Guidance and Training Materials.
