Some of the aspiring patent agent candidates that I see assume that they can simply rely on their scientific or engineering brilliance to land a job with a top law firm.
In order to be qualified to sit for the Patent Bar exam, a candidate needs to have at least a bachelor’s degree in a scientific or engineering field. Passing the exam is not easy. Typical pass rates are around 33% (give or take 6% or so). Thus, passing this exam will say something very positive about your knowledge and abilities to be a successful patent prosecutor. So will solid patent prosecution experience. Failure to present either one or both of these things will substantially weaken your presentation as a patent agent candidate.
