MPEP Chapter 2100: Patentability — Study Guide

Chapter 2100 is by far the highest-weight chapter on the patent bar — nearly half of all released exam questions touch patentability. It covers patent-eligible subject matter (35 U.S.C. 101), novelty (102), nonobviousness (103), and the disclosure requirements (112). This chapter alone can decide your exam.
