The full breakdown

What's on the Patent Bar exam — and how to pass it.

The USPTO registration examination (“the Patent Bar”) is the gate to becoming a registered patent agent or patent attorney. It’s a 100-question, multiple-choice, computer-delivered exam — and it is open-book on the MPEP. That doesn’t make it easy: the first-time pass rate hovers around 50%, the exam fee plus testing-center seat is not cheap, and a failed sitting means another wait and another fee.

What’s on the exam

The exam is drawn exclusively from the Manual of Patent Examining Procedure (MPEP), 35 U.S.C., and 37 CFR. The questions are application-style — they test whether you can find and apply the right rule, not whether you’ve memorized it:

  • Patentability (MPEP 2100, ~28%) — 35 U.S.C. 101 eligibility, 102 novelty and prior art under the AIA first-inventor-to-file regime, 103 obviousness (the Graham/KSR framework), 112 specification and claim requirements, and double patenting. This is the highest-yield chapter on the exam.
  • Examination & Prosecution (MPEP 700, ~22%) — Office actions, rejections vs objections, responses and amendments, final-rejection and after-final practice (RCE), restriction, abandonment and revival, and the extension-of-time rules.
  • Application Parts & Filing (MPEP 600, ~13%) — specification, claims, drawings, oath/declaration and the application data sheet, filing-date requirements, benefit and priority claims, and continuing applications.
  • Appeals (MPEP 1200, ~10%) — Notice of Appeal, appeal brief, examiner’s answer, reply brief, the PTAB, and the time periods.
  • PCT / International (MPEP 1800, ~8%) — international filing, international-phase time limits, and national-stage entry under 35 U.S.C. 371.
  • Post-grant, reissue & reexamination, rules of practice and ethics, and patent term round out the remainder — reissue, ex parte reexamination, the 37 CFR 1.56 duty of disclosure, professional conduct, and patent term.

Why open-book is its own trap

Candidates assume open-book means easy. It doesn’t. With ~100 questions and a finite clock, you can’t look everything up — you have to know the MPEP’s structure cold so you can navigate straight to the controlling section. The exam is engineered around procedural precision: an exact deadline, the right review route (rejection → PTAB vs objection → petition), the correct AIA prior-art classification. Miss the section and you burn time you don’t have.

How PassFirst helps

  • Adaptive practice on the section-finding skill the exam measures. Our Rasch-based engine surfaces fresh questions on the leaves where you’re weakest — 102/103, response-and-amendment practice, appeal deadlines — so you build the reflex of routing a fact pattern to the right MPEP chapter, fast.
  • Layered AI question generation grounded in the MPEP. Every practice item is generated from the authoritative public-domain sources (the MPEP chapters, 35 U.S.C., 37 CFR served by uspto.gov), graded by a separate model, and verified claim-by-claim against the cited section. Every correct answer points you to its MPEP section, statute, or rule.
  • Current law, not stale law. Patent practice changed materially with the America Invents Act (first-inventor-to-file). Our items reflect the current MPEP and the AIA 102/103 regime — no pre-AIA swearing-behind or interference traps unless a question expressly invokes a pre-AIA application.
  • A patent prosecutor’s tutor mode. Stuck on whether the right move after final is an RCE, a continuation, or an appeal? Ask why. Get a Socratic walk-through that names the rule, the citation, and the procedural logic — the way a senior practitioner would explain it.
  • Scenario drills. Real exam questions are fact patterns. We drill Office-action-response, prior-art-classification, and PCT national- stage scenarios — the exact form the registration exam uses.

Built for scientists, engineers, and law students sitting the USPTO registration examination. Federal — one nationwide exam, no state supplements.

Why candidates switch

The category looks identical. We're the exception.

Every other Patent Bar app is the same rectangle of question, four buttons, one big "Next." It works — and it's genuinely uninspiring.

The incumbent app

  • Shows the answer, never the reasoning
  • Same random questions for everyone
  • No way to practice the out-loud parts
  • Streaks, timers, and leaderboards that add pressure
  • Content that quietly goes stale

The honest answers.

Will this actually get me to pass?

No app can guarantee a pass — anyone who promises that is lying to you. What we can do is target your weak topics, teach the reasoning behind every miss, and give you an honest readiness signal before you sit the exam. Most candidates who reach "ready" on our diagnostic pass on the first try.

Is the content current for 2026?

Yes. Questions are generated and checked against the current Patent Bar source documents, then re-ingested on a schedule when those documents change. We don't ship loosely paraphrased material.

Can I get a refund?

If PassFirst isn't right for you, email us within 14 days for a full refund — no rage-bait "are you sure?" flow, no hoops. We'd rather you trust us than feel trapped.

What if the rules change?

The question pool tracks the current federal source documents. When the regulations update, the affected questions are regenerated and re-verified — and your access carries through it.

Do you have my exam version?

This is a federal credential, so the question pool is scoped to exactly the federal knowledge sections you'll be tested on — no state variations to worry about.
