Patent Bar Exam — Study Plan Built from the MPEP Itself

Roughly half of all takers fail the patent bar. The corpus is free — the MPEP, the statutes, and the rules are all public domain — but it is ~35,000 minutes of reading, and the open-book search is far weaker than people assume. exclam.ai builds a dated plan over the real MPEP and trains chapter-and-section localisation: the one skill that moves your score.

Pass rates — half of all takers fail

USPTO-published results. The rate has been stable at 45-49% for five straight fiscal years — this is a hard exam, and it earns a real plan.

What's actually tested

The USPTO publishes no official outline or per-chapter weighting. The tiers below are vendor estimates and candidate-reported patterns — directional, not official, and labeled as such.

Tier 1 — heaviest tested

~35-40% of the exam
MPEP 700Examination of Applications — rejections, responses, after-final practice
MPEP 2100Patentability — §§101/102/103/112 doctrine
MPEP 600Parts, Form, and Content of Application

Tier 2 — reliably present

Substantial share every sitting
MPEP 1200Appeals to the PTAB
MPEP 1400Correction of Patents — reissue, certificates of correction
MPEP 1800PCT international applications
MPEP 200Types, Cross-Noting, Priority claims

Tier 3 — steady minor share

A few questions each
MPEP 300 / 400Ownership, assignment, representation
MPEP 500Receipt and handling of mail and papers
MPEP 2200+Reexamination, IPR/PGR post-grant practice
37 CFR Part 11Ethics — the USPTO tests practitioner conduct directly

The free corpus — everything the exam draws from

All of it is a work of the U.S. federal government, public domain under 17 U.S.C. §105. Note the three named source documents that are NOT inside the MPEP — most self-studiers miss them.

The skill that moves your score: knowing where rules live

The open-book viewer searches one chapter at a time, and candidates realistically look up only 20-30 of 100 questions. The binding constraint is not "can I find it" — it is "do I know which of 29 chapters it lives in." exclam.ai trains that topic → chapter → section map directly.

Sample localisation drills
After-final practiceMPEP 700 → 714.12-714.13
Restriction between speciesMPEP 800 → 806.04
Certificate of correction, applicant's mistakeMPEP 1400 → 1480
PCT Chapter II demand deadlineMPEP 1800 → 1842 / 1864
Petition to withdraw holding of abandonmentMPEP 700 → 711.03(c)

Plan over the real MPEP

A dated daily plan across the heavily-tested chapters and appendices — ~35,000 minutes of corpus, weighted so the reading actually finishes.

Chapter-map training

Quizzes that ask where the rule lives, not just what it says — because 70-80 of your 100 questions must be answered without a lookup.

MPEP-version-true answers

The exam tests Rev. 01.2024, frozen at January 31, 2024 law. Study material pinned to the tested revision — not current law that will mark you wrong.

Patent bar questions

What is the patent bar pass rate?

Stable at 45-49% over the last five fiscal years per USPTO statistics — FY2025 was 46% across 2,278 administrations. Roughly half of all takers fail.

Is the patent bar open book?

Technically yes, practically barely. The testing software shows one MPEP chapter at a time from a dropdown, with a Find button that searches only the open chapter. Candidates realistically look up 20-30 of 100 questions; 70-80 must be answered from memory or reasoning.

Which MPEP revision does the exam test?

Ninth Edition, Revision 01.2024 — and only law as of January 31, 2024. Later guidance (2024 eligibility updates, FY2025 fee changes) is NOT tested. Answer per the MPEP, not per current law.

How long does patent bar prep take?

Common guidance is 150-300 hours over 2-4 months. The full corpus is ~35,000 minutes of reading, which no one does linearly — a weighted plan over the heavily-tested chapters is the only realistic route.

Do design patent practitioners take a different exam?

No. Since January 5, 2024 the USPTO admits design-only practitioners, but they take the same registration exam — only the scientific/technical eligibility requirements differ.

What does the exam cost?

Fees are set in the General Requirements Bulletin and change with USPTO fee cycles — verify the current application and exam fees at uspto.gov before applying.
