Complete Overview

The Patent Bar, formally the USPTO registration examination, is the test the United States Patent and Trademark Office uses to decide who may represent inventors before the Office in patent matters. It is 100 multiple-choice questions delivered by Prometric across two three-hour sessions, 50 questions in the morning and 50 in the afternoon, for six hours of testing time. Sitting it costs $118 for the non-refundable application fee plus a $226 registration examination fee to the USPTO, and Prometric charges its own $221 examination administration fee when you schedule. Passing and then registering costs a further $226 on registration to practice under 37 CFR 11.6.

Ten of the 100 questions are unscored beta items that are not identified on the paper. You must answer 63 of the 90 scored questions correctly, which is 70 percent. Each question has five answer choices. The USPTO published pass rates of 45 percent for fiscal year 2021, 46 percent for 2022, 46 percent for 2023, 49 percent for 2024 and 46 percent for 2025.

Candidates are scientists and engineers, not lawyers. No law degree is required. What is required is scientific and technical qualification under one of four categories set out in the Office of Enrollment and Discipline's General Requirements Bulletin: Category A for a bachelor's, master's or doctoral degree in a listed technical subject, Category B for another degree backed by specified coursework, Category C for passing the Fundamentals of Engineering test alongside a bachelor's degree, and Category D for design subjects, which registers you for design patent matters only. Passing without a law degree makes you a registered patent agent; a licensed attorney who passes becomes a registered patent attorney.

The USPTO will update the registration examination on September 23, 2026, and no examination is administered from September 17 through September 22, 2026 while the change is made. Both the current and the updated exam cover the subject matter identified in the published source materials, so the update is a refresh of the question pool against those materials rather than a new syllabus, but a candidate whose window straddles that date should schedule around the blackout and re-check the source materials list, which the USPTO revises from time to time.

The exam is open reference in a narrow sense. The USPTO makes the searchable source materials available on the exam computer, currently the Manual of Patent Examining Procedure Ninth Edition Revision 01.2024 published November 2024, the Consolidated Trial Practice Guide of November 2019, the Changes to Representation of Others Before the USPTO final rules, and the Global and IP5 Patent Prosecution Highway pilot notice. External links inside those materials are redacted during the exam and there is no access to outside websites. Bringing your own notes, printed material or scratch paper is prohibited.

Candidates who take both sessions in a single day get unofficial results on screen at the end. Official results are mailed by OED, generally within about five business days. A candidate who fails may, within 60 days of the mailing date of the notice of results, review but not copy the scored questions they answered incorrectly, once per examination, either at a Prometric site or at OED in Alexandria, Virginia. The session runs two and a half hours and costs $300 payable to Prometric; questions you answered correctly, questions you skipped and the ten beta questions are not reviewable. On retaking, the eligibility window starts no sooner than 30 days after an unsuccessful attempt, and you reapply with a fresh $118 application fee and $226 examination fee. The USPTO has temporarily waived the rules in 37 CFR 11.7(b)(2) that otherwise impose a longer wait between attempts and require a petition to sit more than five times, so under the waiver you may reapply immediately and the 30-day eligibility gap is the only constraint; when the waiver expires both restrictions return.

Why Get Patent Bar (USPTO Registration Exam) Certified?

Passing makes you a registered patent agent, which allows you to prepare and prosecute patent applications before the USPTO without a law degree and without going to law school.

The USPTO reported a 46 percent pass rate for fiscal year 2025, so the credential separates candidates in a way a technical degree does not.

There is no residency, citizenship or state bar requirement to become a patent agent, so the qualification travels across all fifty states rather than being tied to one jurisdiction.

Registration under 37 CFR 11.6 is not time-limited and the USPTO fee schedule carries no annual renewal fee for practitioners, only a $54 delinquency fee and a $226 administrative reinstatement fee if you fall out of compliance with contact and registration statement requirements.

The exam is computer-delivered year round rather than only in fixed windows, so you schedule around your own preparation rather than around a sitting calendar.

Law students and science graduates who pass before entering a firm arrive already able to sign and file, which is why technical specialist and patent engineer roles pay for the exam.

The full source material is free: the MPEP, the Consolidated Trial Practice Guide and the two rule notices are all published on uspto.gov, so preparation can cost nothing beyond the fees.

Recommended Study Plan

Week 1: Eligibility, application and the source materials
8-10 hours
  • 1Download the General Requirements Bulletin from uspto.gov and decide which of Categories A, B, C or D you qualify under.
  • 2Order an official transcript bearing the university stamp or seal; the USPTO does not accept a diploma or a copy of a transcript.
  • 3File Form PTO-158 with the $118 non-refundable application fee and the $226 registration examination fee, and answer questions 14 through 21 completely.
  • 4Download the four named source materials: MPEP Ninth Edition Revision 01.2024, the Consolidated Trial Practice Guide of November 2019, the Changes to Representation of Others final rules, and the Global and IP5 PPH notice.
  • 5Read MPEP Chapter 100 and 200 headings to learn the numbering scheme, because searching by section number is faster than searching by keyword on exam day.
Week 2: MPEP navigation and search technique
12-14 hours
  • 1Practise finding an answer in the MPEP inside 90 seconds using the electronic version's search, since 90 scored questions in 360 minutes leaves four minutes each.
  • 2Build a personal index of the twenty MPEP sections you expect to need most, keyed to the concepts rather than the chapter titles.
  • 3Note that external links inside the reference materials are redacted during the exam, so learn to navigate within the documents rather than out of them.
  • 4Work through MPEP Chapter 2100 section 2106 on subject matter eligibility, the longest single block in the manual.
  • 5Time yourself on twenty practice questions using only the MPEP, with no notes.
Week 3: Patentability: 35 U.S.C. 101 and 112
12-14 hours
  • 1Study 35 U.S.C. 101 subject matter eligibility and the utility requirement.
  • 2Work 35 U.S.C. 112(a) written description, enablement and best mode.
  • 3Cover 112(b) definiteness and 112(f) means-plus-function interpretation.
  • 4Practise identifying whether a described rejection is proper and what reply is available.
  • 5Log every question you get wrong by MPEP section, not by topic name.
Week 4: Prior art under 102 and obviousness under 103
14-16 hours
  • 1Learn the AIA 35 U.S.C. 102 prior art categories and the 102(b) exceptions cold, since the manual is slow to search on this topic.
  • 2Study the grace period and the inventor-originated disclosure exception.
  • 3Cover pre-AIA 102 subsections, which still govern applications filed before March 16, 2013.
  • 4Work 35 U.S.C. 103 obviousness, the Graham factors and the common ownership exception under 102(b)(2)(C).
  • 5Drill effective filing date questions, which combine benefit claims with prior art dates.
Week 5: Application filing and formalities
12-14 hours
  • 1Study filing date requirements and what a notice to file missing parts requires.
  • 2Cover the inventor's oath or declaration and substitute statement practice.
  • 3Learn micro entity, small entity and undiscounted fee eligibility and the consequences of an incorrect assertion.
  • 4Work provisional application practice, including conversion and the 12-month benefit period.
  • 5Study assignments, recordation, power of attorney and customer number practice.
Week 6: Prosecution and reply practice
14-16 hours
  • 1Study statutory and shortened statutory periods and the extension of time rules in 37 CFR 1.136.
  • 2Work through what constitutes a proper reply to a non-final and a final Office action.
  • 3Cover restriction requirements, election with and without traverse, and rejoinder.
  • 4Learn statutory and non-statutory double patenting and when a terminal disclaimer cures it.
  • 5Study abandonment and revival, including the unintentional delay standard.
Week 7: Benefit, priority and continuing applications
12-14 hours
  • 1Study 35 U.S.C. 120 benefit claims, copendency and the specific reference requirement.
  • 2Cover 35 U.S.C. 119(e) provisional benefit and 119(a) to (d) foreign priority with certified copies.
  • 3Work continuation, divisional and continuation-in-part practice under 37 CFR 1.53.
  • 4Study request for continued examination practice and how it differs from a continuation.
  • 5Drill delayed benefit and priority claim petitions.
Week 8: PCT and international practice
14-16 hours
  • 1Work MPEP Chapter 1800 systematically, since PCT questions are heavily date-driven and reward pattern recognition.
  • 2Learn the 30-month national stage deadline and what must be filed under 35 U.S.C. 371.
  • 3Cover the international search report, written opinion, Chapter II demand and international preliminary examination.
  • 4Study Article 19 and Article 34 amendments and when each is available.
  • 5Read the Global and IP5 Patent Prosecution Highway pilot notice, which is a named exam source material.
Week 9: Appeals and PTAB
12-14 hours
  • 1Study the notice of appeal, appeal brief requirements under 37 CFR 41.37 and the examiner's answer.
  • 2Cover new grounds of rejection in an answer and the applicant's options in response.
  • 3Work reply brief timing, oral hearing requests and Board decision outcomes.
  • 4Read the Consolidated Trial Practice Guide of November 2019, another named source material.
  • 5Cover the basic structure of inter partes review and post-grant review.
Week 10: Post-issuance and ethics
12-14 hours
  • 1Study reissue practice, the reissue oath, broadening reissue within two years and the recapture rule.
  • 2Cover ex parte reexamination, the substantial new question standard and supplemental examination.
  • 3Learn maintenance fee windows, grace periods and surcharges.
  • 4Work 37 CFR Part 11 professional conduct rules and 37 CFR 11.18 signature certifications.
  • 5Study the duty of disclosure under 37 CFR 1.56 and information disclosure statement timing tiers.
Week 11: Full-length timed practice
16-18 hours
  • 1Sit two full 100-question papers split into two three-hour halves with a one-hour break, mirroring the real schedule.
  • 2Use only the MPEP and the other three source materials, with no personal notes, since notes are prohibited in the testing room.
  • 3Track how many questions you answered from memory versus by lookup; lookups above roughly a third of the paper mean you will run out of time.
  • 4Rework every miss and record the MPEP section that contained the answer.
  • 5Practise flagging and returning, since you may review any question within a session.
Week 12: Weak area repair and test centre logistics
12-14 hours
  • 1Spend most of the week on the two areas where lookups cost you the most time, usually PCT dates and post-issuance deadlines.
  • 2Schedule with Prometric if you have not already, paying the $221 examination administration fee at the time of scheduling.
  • 3Check that your government-issued photo ID with a signature is current and that the name matches line 1b of your application exactly.
  • 4Confirm your admission letter's scheduling window has not expired; extensions cost $124 each and must be requested before the window closes.
  • 5Plan a lunch you can eat quickly, since the scheduled break is one hour and unscheduled breaks let the clock run.

Common Mistakes to Avoid

Treating an open-reference exam as one you can pass by looking everything up.

Ninety scored questions in 360 minutes gives four minutes each, and the MPEP runs to thousands of pages. Aim to answer at least two thirds from memory and reserve searching for date rules and specific section numbers, which is exactly what searching is good at.

Studying an older MPEP revision because it was the one a prep course was built around.

OED names the exact version tested, currently the Ninth Edition Revision 01.2024 published November 2024, and warns that source materials may be revised during your examination window. Check the source materials page again in the fortnight before you sit.

Expecting to follow a hyperlink inside the MPEP during the exam.

OED redacts every external link in the reference materials at the test centre, and there is no access to outside websites. Practise navigating inside each document by section number so that a dead link does not cost you a minute.

Submitting a diploma or a photocopy of a transcript with the application.

The GRB requires an official transcript including the university stamp or seal. A diploma, a copy of a diploma, or a copy of a transcript will not be accepted, and an incomplete application delays admission rather than being fixed at the test centre.

Letting the admission letter's scheduling window expire.

The admission letter specifies a period in which you must schedule and sit. Once it expires you must file a new application and pay all fees again. A 90-day extension costs $124 under 37 CFR 1.21(a)(1)(iv) and must be received before the current period expires, or the fee is refunded and nothing is granted. OED has temporarily extended the standard scheduling window to 180 days until further notice, which reduces how often the extension is needed.

Skipping a scheduled appointment and assuming the fees carry over.

An applicant who does not appear for a scheduled examination forfeits all fees previously paid to the USPTO and loses eligibility at Prometric. If time remains in the testing period you must contact OED, not Prometric, to reset eligibility; if it does not, you reapply from scratch.

Ignoring pre-AIA 35 U.S.C. 102 because the AIA replaced it.

Applications filed before March 16, 2013 are still governed by pre-AIA rules, and the MPEP carries both frameworks. Questions can turn on which regime applies before they turn on the substantive rule, so learn the trigger dates first.

Bringing notes, printed outlines or your own scratch paper to the test centre.

No documents, materials, machines or electronic devices may be brought in. Prometric supplies scratch paper and a pencil, collects both at the end and destroys the paper. Leaving the testing area to check notes stored elsewhere is listed by OED as cheating.

Assuming a failed attempt lets you see the whole exam afterwards.

You may review, but not copy, only the scored questions you answered incorrectly, and only within 60 days of the mailing date of the notice of results. One review session is allowed per examination, taken by computer at a Prometric site or at OED in Alexandria, Virginia, with no notes permitted.

Exam Day Tips

  • 1

    Bring one current, valid State or Federal government-issued ID containing both your photograph and your signature, such as a driver's licence or passport. A single ID meeting both requirements is enough.

  • 2

    The name on that ID must match the name on line 1b of your application exactly. A mismatch, or an expired ID, means you are denied admission, and no name changes are permitted at testing centres.

  • 3

    Do not present your admission letter as identification. OED states an admission letter will not be accepted for admission to the testing centre.

  • 4

    Arrive 30 minutes before your appointment for check-in. An applicant arriving late will not be admitted to or allowed to take the examination.

  • 5

    Leave everything in the Prometric locker. No documents, materials, machines or electronic devices enter the room, including computers, phones, recording devices, cameras and typewriters.

  • 6

    Use the scratch paper and pencil Prometric provides. You may not bring your own, all of it is collected at the end of the session, the paper is destroyed and none of it may leave the centre.

  • 7

    Expect to sign a signature log, have an electronic photograph taken, and have your entry and exit times recorded. The testing area is under continuous video monitoring and staffed proctoring.

  • 8

    Take the optional one-hour lunch break between sessions. It is the only timed and scheduled break built into the day; any other break you take runs against your own exam clock.

  • 9

    Use the 15-minute tutorial before the exam to rehearse the search function on the reference materials, because that is the tool you will lean on for six hours.

  • 10

    If you take both sessions in a single day, you get unofficial results on screen at the end. Official results are mailed by OED, generally within about five business days.

Career Paths & Salary Ranges

Registered patent agent

Drafts and prosecutes patent applications before the USPTO without a law degree. Passing the registration examination under Category A, B or C is the entire qualification, and a Category D pass registers you for design patent matters only.

$90k-$200k+

Registered patent attorney

A licensed attorney who has also passed the registration examination. The combination allows both USPTO prosecution and litigation, opinion and transactional work that a patent agent cannot perform.

$90k-$200k+

Technical specialist or patent engineer

A law firm role for a scientist or engineer, often held while attending law school. Firms frequently fund the exam because a registered technical specialist can sign and file rather than only draft under supervision.

$90k-$200k+

In-house patent counsel or IP manager

Runs a company's patent portfolio, manages outside counsel and handles invention disclosure review. Registration allows direct filing and prosecution rather than routing everything through a firm.

$90k-$200k+

Solo or boutique patent practitioner

Registration under 37 CFR 11.6 carries no state boundary, so a registered practitioner can serve clients nationwide. There is no annual USPTO renewal fee in the current fee schedule, which keeps overheads low for a small practice.

$90k-$200k+

Prerequisites & Requirements

  • Scientific and technical qualification under one of four categories in the General Requirements Bulletin. Category A is a bachelor's, master's or doctoral degree in a listed technical subject such as electrical engineering, biochemistry, microbiology, molecular biology, materials science or mechanical engineering.
  • Category B applies to a degree in another subject supported by specified coursework, through one of four options: 24 semester hours in physics for physics majors; 32 semester hours combining 8 hours of chemistry or physics including a lab with 24 hours of biology, botany, microbiology or molecular biology; 30 semester hours in chemistry for chemistry majors; or 40 semester hours combining 8 hours of chemistry, physics or biology including a lab with 32 hours of those subjects.
  • Category C applies to applicants relying on practical engineering or scientific experience, who must have taken and passed the Fundamentals of Engineering test administered by a State Board of Engineering Examiners and must also submit an official transcript showing a bachelor's degree.
  • Category D covers design subjects including architecture, applied arts, art teacher education, fine or studio arts, graphic design, industrial design and product design, and registers a successful applicant for design patent matters only.
  • An official transcript with the university stamp or seal is required. A diploma, a copy of a diploma or a copy of a transcript will not be accepted.
  • No law degree is required to sit the examination or to register as a patent agent.
  • Applicants must answer questions 14 through 21 on Form PTO-158 completely, covering good moral character and reputation, and must update OED within 30 days of any event that changes an answer.
  • The $118 application fee and the $226 registration examination fee must both be submitted before OED will evaluate your qualifications.

Frequently Asked Questions

How much does the Patent Bar exam cost?

Three fees to sit it: a $118 non-refundable application fee under 37 CFR 1.21(a)(1)(i), a $226 registration examination fee to the USPTO for test administration by a commercial entity, and a $221 examination administration fee that Prometric collects when you schedule. On passing, registration to practice under 37 CFR 11.6 costs a further $226. The $226 examination fee is refunded if you are disapproved for admission; the $118 application fee never is.

How many questions are on the Patent Bar exam and how long is it?

100 multiple-choice questions with five answer choices each, split into a three-hour morning session of 50 questions and a three-hour afternoon session of 50 questions, six hours in total. A 15-minute tutorial runs before the exam and a 15-minute survey after it, and there is an optional timed and scheduled one-hour lunch break between sessions.

What is the passing score for the Patent Bar?

You must answer 63 of the 90 scored questions correctly, which is 70 percent of the scored questions. Ten of the 100 questions are unscored beta items being psychometrically evaluated for use on future exams; they are not identified on the paper and do not affect your result.

What is the Patent Bar pass rate?

The USPTO publishes pass rates by fiscal year: 45 percent in 2021, 46 percent in 2022, 46 percent in 2023, 49 percent in 2024 and 46 percent in 2025. The Office also states that candidates achieving an unofficial score of 70 percent or more are informed that they passed.

How soon can you retake the Patent Bar after failing?

Your eligibility window to retake starts no sooner than 30 days after an unsuccessful attempt, and you may reapply as soon as you receive notice of failure from OED by submitting a completed Form PTO-158 with a fresh $118 non-refundable application fee and a $226 registration examination fee. The USPTO has temporarily waived 37 CFR 11.7(b)(2), which otherwise requires an additional wait between attempts and a petition to sit a sixth or later attempt; when the waiver expires those restrictions apply again. Eligibility for retesting is controlled by OED, and OED asks that you not direct retesting questions to Prometric.

Can you see which questions you got wrong?

Yes, within limits. Within 60 days of the mailing date of the notice of results, an unsuccessful applicant may review, but not copy, the scored questions they answered incorrectly. The session lasts two and a half hours and costs $300 payable to Prometric. It happens by computer at a Prometric test site or at OED, 600 Dulany Street, Madison West, 8th Floor, Alexandria, Virginia. Questions you answered correctly, questions you skipped and the ten unscored beta questions are all excluded from the review. No notes may be taken and no copies obtained, and only one review session is allowed per examination taken.

When do you get Patent Bar results?

A candidate who takes the morning and afternoon sessions in a single day receives unofficial results on screen at the end of the examination. Official results are released by OED and mailed to the applicant, generally within about five business days of the examination date. Applicants who pass also receive instructions for completing the registration process.

What reference materials can you use during the exam?

The searchable source materials are loaded on the exam computer: the MPEP Ninth Edition Revision 01.2024 published November 2024, the Consolidated Trial Practice Guide of November 2019, the Changes to Representation of Others Before the USPTO final rules, and the Global and IP5 Patent Prosecution Highway pilot notice. Every external link inside those materials is redacted, and there is no access to outside websites. You may not bring reference materials, study materials, notes or scratch paper into the testing area.

What ID is required at the test centre?

One current, valid State or Federal government-issued ID containing both your photograph and your signature, such as a driver's licence or passport. The name on it must appear exactly as on line 1b of your application. You will be denied admission if the names do not match exactly or if the ID is not valid at the time you seek admission, and no name changes are permitted at testing centres.

Do you need a law degree to take the Patent Bar?

No. The requirement is scientific and technical qualification under Category A, B, C or D of the General Requirements Bulletin, not legal education. A passing candidate without a law licence registers as a patent agent and may prepare and prosecute patent applications before the USPTO. A licensed attorney who passes registers as a patent attorney.

What if your degree is not on the Category A list?

You qualify through Category B by documenting equivalent coursework, through one of four options: 24 semester hours in physics for physics majors, 32 semester hours combining 8 hours of chemistry or physics including a lab with 24 hours of biology, botany, microbiology or molecular biology, 30 semester hours in chemistry for chemistry majors, or 40 semester hours combining 8 hours of chemistry, physics or biology including a lab with 32 hours of those subjects. Quarter or trimester credit hours convert to semester hours by multiplying by two thirds. Category C is the alternative route, requiring a passed Fundamentals of Engineering test plus an official transcript showing a bachelor's degree.

Are testing accommodations available?

Yes. OED provides a Request for Reasonable Accommodation package, Form PTO 158RA, for applicants with a mental or physical medical condition. Answer every question in the package, because an incomplete request can leave the USPTO with insufficient information to grant the accommodation. After OED grants an accommodation you must call the Reasonable Accommodations Department at the Prometric Contact Center, and scheduling may take up to 30 days.

Does the Patent Bar registration expire?

Registration under 37 CFR 11.6 is not time-limited and the current USPTO fee schedule contains no annual practitioner renewal fee. However, 37 CFR 11.11 requires you to notify OED of your office postal address, one to three email addresses and a business telephone number, and any change to them, within 30 days. Practitioners may also be required biennially to file a registration statement confirming they wish to remain active. Failing to comply leads to a notice demanding compliance and a $54 delinquency fee within 60 days, and can end in administrative suspension; administrative reinstatement costs $226.

Is there continuing legal education for registered patent practitioners?

The USPTO's fee schedule imposes no mandatory continuing education fee or requirement to remain registered. Attorneys who are also registered practitioners remain subject to whatever continuing legal education their state bar imposes, which is a state requirement rather than a USPTO one.

How long do you have to complete registration after passing?

Two years from the date of the notice of passing the registration examination. An applicant who does not complete the registration process within that period must take the examination again. Registration also requires the fee on registration to practice under 37 CFR 11.6, currently $226.

What happens if you miss your scheduled appointment?

You lose your eligibility at Prometric and forfeit all fees previously paid to the USPTO. If sufficient time remains in your testing period you may contact OED to reset your eligibility; if not, you must reapply for admission. Late arrivals are treated the same way, since an applicant arriving late is not admitted to the examination.

How does the Patent Bar compare with a state bar exam?

They test different things and neither substitutes for the other. The state bar admits you to practise law in one jurisdiction and requires a law degree; the USPTO registration examination admits you to represent applicants before the USPTO in patent matters nationwide and requires a technical background instead. A patent agent who passes only the USPTO exam cannot give legal advice outside USPTO patent practice, and an attorney who has not passed the registration examination cannot prosecute patent applications before the Office.

Can the USPTO recommend a prep course?

No. The General Requirements Bulletin states the Office cannot identify or recommend courses for preparing for the examination, nor advise on the special training required. OED also will not counsel an applicant on the patent statutes, rules, policy, practice or procedure. All the source material is published free on uspto.gov, so any commercial course is an optional convenience rather than a requirement.

What is changing on the Patent Bar exam in September 2026?

The USPTO will update the registration examination on September 23, 2026, and blacks out testing from September 17 through September 22, 2026 while the update is made. Both the current and the updated examination cover the subject matter identified in the published source materials, which currently include the MPEP Ninth Edition Revision 01.2024. The USPTO tells applicants to check the source materials list regularly, because it can be revised at any time, including partway through an examination window.

How long does the whole Patent Bar process take, from application to registration?

OED review of an application typically takes four weeks or less. On approval you receive a notice of admission with a scheduling window; that window is normally about 90 days, though OED has temporarily extended it to 180 days until further notice, and 90-day extensions are available for a $124 fee under 37 CFR 1.21(a)(1)(iv). After passing, OED publishes the names and postal addresses of passing applicants for a 45-day public comment period on good moral character. Absent adverse information, the certificate of registration and welcome letter generally arrive about three months after the examination.

What does it cost to reschedule a Patent Bar appointment?

Prometric collects the reschedule fee, and it depends on notice. Rescheduling 31 or more calendar days before the appointment is free. Rescheduling 6 to 30 days ahead costs $60. Rescheduling 0 to 5 days ahead costs $221, the same as the original examination administration fee. Rescheduling only moves you within your existing examination window; if you need more window, that is the separate $124 extension fee.
