Who can take the patent bar?
What is the patent bar?
The patent bar, officially known as the United States Patent and Trademark Office Registration Examination, is the exam that will allow you to practice as a patent practitioner. If you have a law degree and have passed a state bar exam, passing the patent bar will allow you to be a patent attorney. If you do not have a law degree, it will allow you to be a patent agent.
What is the difference between a patent agent and a patent attorney?
Both patent agents and patent attorneys can draft and file patent applications, prosecute those applications before the USPTO (responding to office actions, arguing for allowance, and so on), and represent clients before the Patent Trial and Appeal Board. In other words, when it comes to work inside the USPTO, they have the same authority.
The difference shows up outside the patent office. Because a patent attorney has also passed a state bar exam, they can do things a patent agent cannot: draft licensing agreements, litigate patent infringement cases in federal court, give legal opinions on infringement or validity, and offer general legal advice that touches on other areas of law. A patent agent's practice is limited strictly to patent prosecution matters before the USPTO.
So if your goal is purely to write and prosecute patent applications, becoming a patent agent may be all you need. If you want the flexibility to litigate, negotiate deals, or practice law more broadly, you'll need a law degree, state bar admission, and the patent bar exam to become a patent attorney.
What qualifications do you need to take the patent bar?
Patent bar candidates must fall into one of the following categories:
Category A: Possess a Bachelor's Degree, Master's Degree, or Doctor of Philosophy Degree in a Recognized Technical Subject. You'll need to provide an official transcript showing that you have received one of the acceptable degrees from an accredited US university, or the equivalent from a foreign university. For a full list of degrees, see the USPTO's official list, but it includes degrees in science, technology, and engineering such as most types of engineering (Aeronautical, Electrical, Mechanical, Nuclear, Mining, Chemical, Civil, Computer, Industrial, Materials, etc.), Biochemistry, Biology, Botany, Food Technology, Chemistry, Genetics, Microbiology, Molecular Biology, Neuroscience, Organic Chemistry, Pharmacology, or Physics. Degrees where the transcript demonstrates equivalence to one of the degrees in Category A (such as a degree in Materials Science Engineering with Materials Science) will also be accepted.

Degrees where the transcript demonstrates equivalence to one of the degrees in Category A (such as a degree in Materials Science Engineering with Materials Science) will also be accepted.
Category B: Possess a Bachelor's Degree, Master's Degree, or Doctor of Philosophy Degree in a different subject but demonstrate equivalent scientific and technical qualifications. To do this, the applicant should satisfy one of the following four options by submitting proper documentation, including official transcripts and official course descriptions.
Option 1: 24 semester hours in physics (only courses for physics majors are accepted)
Option 2: 32 semester hours in a combination as follows: 8 semester hours in a combination of chemistry or physics (with at least one course including a lab) and 24 semester hours in biology, botany, microbiology, or molecular biology. Only courses for science or engineering majors are accepted.
Option 3: 30 semester hours in chemistry (only courses for chemistry majors are accepted)
Option 4: 40 semester hours in a combination as follows: 8 semester hours in a combination of chemistry, physics, or biology, with at least one course including a lab, and 32 semester hours of chemistry, physics, biology, botany, microbiology, molecular biology, or engineering. Only courses for science or engineering majors will be accepted.
Courses that are typically not accepted include those in anthropology, astronomy, behavioral science, public health, management and business administration, history, repair and maintenance courses, and courses teaching skills such as soldering, wiring, or machine operation.
Category C: Practical Engineering or Scientific Experience. An applicant who relies on practical experience and does not qualify under Category A or B may establish the required technical training by passing the Fundamentals of Engineering (FE) exam. The FE exam is developed and administered by state boards of engineering, not by the USPTO, so you'll take it through your state's engineering licensure process.
There's also a Category D, reserved for applicants pursuing the design patent bar instead of the standard patent bar. It uses the same registration exam, but it's built for people with a design background rather than a science or engineering degree. Once registered, a design practitioner can only handle design patent matters, and must disclose that limitation to clients.
In addition to possessing the required scientific and technical qualifications, you must be either a US citizen, a US national, or a qualifying non-US citizen (for example, a lawful permanent resident, or someone with immigration authorization consistent with representing patent applicants), and you must be "of good moral character and reputation." The USPTO reviews this as part of your application, and any doubt about how to answer the moral character questions on the application should be resolved in favor of disclosure.
What kind of job can you get as a patent agent or patent attorney?
Patent agents and patent attorneys typically work in a few common settings:
-
Law firms, in an intellectual property or patent prosecution group, drafting and filing patent applications and responding to USPTO office actions on behalf of outside clients.
-
In-house at companies, especially in tech, pharma, and manufacturing, managing a company's own patent portfolio and working closely with R&D or engineering teams.
-
The USPTO itself, as a patent examiner, reviewing applications and determining whether inventions merit a patent (USPTO registration is not required to work as an examiner)
-
Solo or boutique practice, particularly for patent agents who want to focus narrowly on prosecution work without the overhead of a large firm.
Patent attorneys generally have access to a wider range of roles, since their state bar license also opens the door to litigation, licensing, and broader IP counseling work that's off-limits to patent agents.
Passing the patent bar is the first step in building a career as a patent practitioner, and figuring out whether you're even eligible is step zero. In the next post, we'll break down what is on the exam so you can start planning your prep.
