Patent attorneys must generally have a technical degree and be admitted to law practice in at least one state. The candidate must either have a degree in a science or engineering, have a certain number of hours in science or engineering, or have passed the Fundamentals of Engineering examination.

Once this examination has been successfullly completed, the attorney is a patent attorney.
