Means-Plus-Function Limitation and Section 112(b) Rejection Checklist

Summary

This checklist provides background and guidance for responding to rejections of pending patent claims in which the examiner interprets a claim limitation containing functional language as invoking 35 U.S.C. § 112(f) (i.e., as a means-plus-function limitation). The checklist also addresses associated rejections for indefiniteness under 35 U.S.C. § 112(b).
