How MPEP 600 Application Parts Is Tested on the 2026 Patent Bar Exam

MPEP Chapter 600 (Parts, Form, and Content of Application) tests the formal rules governing U.S. patent applications. Key focus areas include the Inventor’s Oath or Declaration (37 CFR 1.63) and Substitute Statements (37 CFR 1.64) permitted when an inventor is deceased, legally incapacitated, cannot be found after diligent effort, or refuses to execute the oath.

A second pillar of Chapter 600 is the Application Data Sheet (ADS) under 37 CFR 1.76 (MPEP § 601.05(a)) and the four-tier Information Disclosure Statement (IDS) timeline under 37 CFR 1.97 and 1.98 (MPEP § 609.04(b)). You must memorize what is required at each stage of prosecution (within 3 months of filing or before first Office action; before final action/allowance with either a 1.97(e) statement OR the 1.17(p) fee; after final action/allowance requiring BOTH a 1.97(e) statement AND the 1.17(p) fee; and after payment of the issue fee, which requires an RCE or QPIDS).

Chapter 600 also tests multiple dependent claim numbering and fee calculations (MPEP § 608.01(n)), noting the foundational rule that a multiple dependent claim may never depend from another multiple dependent claim.

Frequently Asked Questions: MPEP 600 Application Parts

When can an applicant file a Substitute Statement under 37 CFR 1.64 instead of an inventor’s oath?

Under 37 CFR 1.64 and MPEP § 602.01(a), an applicant may execute a substitute statement if the inventor is deceased, is under legal incapacity, cannot be found or reached after diligent effort, or has refused to execute the oath or declaration.

What is required to file an IDS after a Notice of Allowance but before payment of the issue fee?

Under 37 CFR 1.97(d) and MPEP § 609.04(b), an IDS filed after a final action or Notice of Allowance (and on or before payment of the issue fee) requires BOTH a 37 CFR 1.97(e) certification statement AND the fee set forth in 37 CFR 1.17(p).

Can a multiple dependent claim depend on another multiple dependent claim?

No. Under 35 U.S.C. 112(e), 37 CFR 1.75(c), and MPEP § 608.01(n), a multiple dependent claim cannot serve as a basis for any other multiple dependent claim. Such a claim is improper and incurs a 112(e) objection/rejection.
