Our subject matter eligibility (SME) guidance explains how Office personnel including patent examiners and PTAB administrative patent judges should evaluate claims for patent subject matter eligibility under 35 U.S.C. 101.
Office guidance
The Office's current eligibility guidance is found in Section 2103 through 2106.07 of the Manual of Patent Examining Procedure (MPEP).
Because rejections are based on the substantive law, the incorporation of the Office's guidance into the MPEP does not affect pending eligibility rejections or create new grounds of rejection.
