Worked examples
- Is an instance
A university TTO receives an unsolicited invention-marketing pitch from someone claiming to be a 'patent specialist.' Before sharing any confidential invention disclosure, the TTO uses OED's public Patent Practitioner Search (oedci.uspto.gov) to confirm the person is an active, registered patent agent or attorney in good standing -- rather than someone with no USPTO registration at all, which would mean they are not legally authorized to prosecute a patent application on the university's behalf.
- Is an instance
A PhD chemist with no law degree applies to OED to sit the registration examination. Because a chemistry bachelor's degree satisfies OED's Category A scientific/technical qualification under the General Requirements Bulletin, OED admits the application, the applicant passes the exam, and OED adds them to the roster as a registered patent agent -- authorized to draft and prosecute patent applications before the USPTO, but not authorized to give general legal advice or represent the university in a licensing negotiation or in federal court, since they hold no state law license.
Counter-examples
Looks similar, but isn't
- Not an instance
A licensed attorney who practices IP litigation but has never applied to OED, sat the registration exam, or been admitted to the roster is not a 'registered patent practitioner' and is not authorized to file or prosecute a patent application before the USPTO on someone else's behalf, regardless of how much patent litigation experience they have -- state bar admission and OED registration are separate credentials that do not substitute for one another.
Editorial commentary
The Office of Enrollment and Discipline (OED) is the office within the U.S. Patent and Trademark Office (USPTO), housed under the agency’s Office of the General Counsel, responsible for deciding who is legally authorized to represent applicants in patent matters before the USPTO, and for policing the conduct of everyone it has admitted. It has two distinct functions that are easy to conflate but worth keeping separate: enrollment (registration) and discipline.
What OED does: registration
Before someone can prosecute a patent application on behalf of an inventor or assignee, they must be admitted to practice before the USPTO in patent matters — commonly called being "registered" or having passed "the patent bar." OED runs this entire process:
- Reviews technical qualifications. Unlike ordinary legal practice, patent prosecution requires proof of a scientific or technical background, because a practitioner has to understand the invention well enough to draft claims that satisfy 35 U.S.C. 112. OED evaluates each applicant’s educational background against the categories set out in its General Requirements Bulletin — broadly, a qualifying bachelor’s degree in an accepted scientific/engineering field, a related degree paired with sufficient coursework, or other documented technical training/practical experience — before admitting anyone to sit the exam.
- Administers the registration examination. The exam is computer-based, offered year-round at commercial test centers, and consists of 100 multiple-choice questions (90 scored), drawn from the current edition of the Manual of Patent Examining Procedure (MPEP). A passing score is 70% of the scored questions.
- Maintains the official roster. Once an applicant passes and submits the required oath and registration fee, OED adds them to the register of patent attorneys and agents — the authoritative list of who may lawfully act as a patent practitioner before the agency.
Passing OED’s exam produces one of two credentials, and the distinction matters for anyone hiring outside patent counsel:
- A patent attorney is a registered practitioner who is also a licensed attorney in at least one U.S. jurisdiction. They can prosecute patents before the USPTO and provide general legal services — draft and negotiate license agreements, litigate infringement, give legal advice.
- A patent agent is a registered practitioner who is not a lawyer. They can prepare and prosecute patent applications before the USPTO with the same technical standing as a patent attorney, but they cannot give general legal advice, draft contracts, or represent a client in court.
OED separately registers a narrower category of design patent attorneys/agents, whose authorization is limited to design patent matters only.
What OED does: discipline
Registered practitioners are bound by the USPTO Rules of Professional Conduct (37 CFR Part 11), a code modeled closely on the ABA Model Rules but specific to practice before the USPTO. OED investigates grievances against practitioners — filed by clients, other practitioners, or raised internally — and, where warranted, prosecutes disciplinary proceedings that can result in a public reprimand, suspension, or exclusion from practice before the USPTO. OED also publishes final disciplinary decisions, which is part of why the practitioner-status check described below returns more than a simple yes/no.
Why this matters for TTOs and researchers
A university technology transfer office routinely works with outside patent counsel — law firms handling prosecution for the institution’s patent portfolio, or occasionally an inventor’s own preferred counsel. Because patent prosecution authority is a distinct credential from a state law license, a TTO evaluating unfamiliar counsel (or fielding an unsolicited approach from someone offering to “patent” a faculty invention) has a concrete, no-cost way to check standing before sharing any confidential invention disclosure: OED’s public Patent Practitioner Search (accessible via USPTO’s “Finding a registered patent practitioner” page, hosted at oedci.uspto.gov) lets anyone look up a name and confirm whether that person is an active registrant, a registered attorney vs. agent, limited to design matters, or subject to any public disciplinary action. This is the same due-diligence step a TTO would apply to any outside counsel engagement, and it costs nothing to run before signing an engagement letter or sharing an invention disclosure form.
Faculty inventors and research staff benefit from understanding this distinction too: a scientific or technical degree alone does not authorize anyone to prosecute a patent, and a general practice attorney without OED registration cannot legally file a patent application on an inventor’s behalf — both are common points of confusion when a researcher is navigating invention disclosure and commercialization for the first time.

Frequently Asked Questions
What does the USPTO Office of Enrollment and Discipline do?
OED is the office within the USPTO’s Office of the General Counsel that decides who may practice patent law before the agency and polices the conduct of everyone it admits. It has two functions: enrollment, which covers reviewing applicants’ qualifications, administering the registration exam, and maintaining the roster of registered patent attorneys and agents; and discipline, which covers investigating and prosecuting violations of the USPTO Rules of Professional Conduct.
What is the difference between a patent attorney and a patent agent?
Both are OED-registered practitioners with the same standing to prepare and prosecute patent applications before the USPTO. A patent attorney is also a licensed attorney in at least one U.S. jurisdiction and can provide general legal services such as drafting license agreements or litigating infringement, while a patent agent is not a lawyer and cannot give general legal advice, draft contracts, or represent a client in court.
How is the OED registration exam (the “patent bar”) scored?
The exam is computer-based and offered year-round at commercial test centers. It consists of 100 multiple-choice questions, 90 of which are scored, drawn from the current edition of the Manual of Patent Examining Procedure (MPEP), and a passing score is 70% of the scored questions.
How can I check whether a patent practitioner is registered with OED or has been disciplined?
OED’s public Patent Practitioner Search, accessible via USPTO’s “Finding a registered patent practitioner” page (hosted at oedci.uspto.gov), lets anyone look up a name and confirm whether that person is an active registrant, a registered attorney or agent, limited to design patent matters, or subject to any public disciplinary action.
What happens if a registered patent practitioner violates the USPTO Rules of Professional Conduct?
OED investigates grievances filed by clients, other practitioners, or raised internally, and where warranted prosecutes disciplinary proceedings that can result in a public reprimand, suspension, or exclusion from practice before the USPTO. OED also publishes its final disciplinary decisions.

"description": "The Office of Enrollment and Discipline (OED) is the office within the U.S. Patent and Trademark Office's Office of the General Counsel that controls who may represent inventors and applicants before the USPTO in patent matters. It performs two distinct functions: (1) it administers registration -- reviewing each applicant's scientific/technical qualifications, developing and administering the registration examination (the 'patent bar exam'), and maintaining the official roster of registered patent attorneys and patent agents -- and (2) it investigates grievances and administers discipline (from a warning through suspension or exclusion) against practitioners who violate the USPTO Rules of Professional Conduct (37 CFR Part 11). An individual is a 'registered patent practitioner' only if OED has admitted them to practice and their name remains on the active roster; passing a state bar exam alone does not confer patent-prosecution authority, and OED registration alone does not confer authority to give general legal advice, draft licenses, or litigate -- those require a state law license, which is why a registered practitioner is either a 'patent attorney' (also a licensed attorney) or a 'patent agent' (not a lawyer, authorized only to prosecute patent applications before the USPTO).",
