# The Patent Bar Exam > The patent bar is the USPTO's Examination for Registration to Practice in Patent Cases: 100 multiple-choice questions in two three-hour sections, taken on computer at a Prometric test center, open book on the MPEP. You need a qualifying technical background to sit it, and passing lets you register as a patent agent, or as a patent attorney if you are also a lawyer.
