About the Patent Bar Exam

The Patent Bar Exam is officially known as the Examination for Registration to Practice in Patent Cases Before the United States Patent and Trademark Office. The exam is given by Thompson Prometric at a computerized testing center. It is 100 multiple choice questions, and a minimum score of 70 is required to pass. The test is given in two 3-hour sections of 50 questions each, one in the morning and one in the afternoon. Takers are given a preliminary pass/fail as soon as they finish. Failing students are told their score, but passing students are only told that they passed, so that the score cannot be used to give one student an advantage over another.

The Patent Bar Exam is considered to be a difficult exam, with an overall pass rate of around 40%.

The version of the MPEP that the exam is based on changes occasionally. The Patent Office announces the change 90 days before it takes place, giving most people time to study and take it before the change occurs.
