and Texas. Per capita, Delaware has more patent attorneys (and agents) than any state (not including DC). Both Patent Attorneys and Patent Agents are generally required to have a technical degree (such as engineering, chemistry or physics) and must take and pass the USPTO registration examination (officially titled Examination for Registration to Practice in Patent Cases Before the United States Patent and Trademark Office, and commonly referred to as the Patent Bar). Patent attorneys must also be admitted to the practice of law in at least one state or territory of the U.S. or in the District of Columbia. Since patent attorneys are admitted to practice law in a state or territory, they can additionally provide legal services outside the Patent Office if practicing within the jurisdiction they are admitted to practice or if the law of the jurisdiction otherwise permits them to practice although not admitted in that jurisdiction. These legal services include advising a client on matters relating to the licensing of the invention; whether to appeal a decision by the Patent Office to a court; whether to sue for infringement; whether someone is infringing upon the claims of a client's issued patent; and conversely, whether a client is infringing the claims of someone else's issued patent. Patent agents cannot provide legal services of this nature, nor can they represent clients before the Trademark Office part of the USPTO. To register as a patent agent or patent attorney, one must pass the USPTO registration examination. This exam, commonly referred to as the "patent bar", tests a candidate's knowledge of patent law and USPTO policies and procedures as set forth in the Manual of Patent Examining Procedure (MPEP). The exam consists of 100 questions in multiple choice format, and is open-book with examinees permitted to use a PDF version of the MPEP. An unofficial score of 70% indicates a passing grade on the exam. Upon successful completion of the examination, one will be labeled as a "patent attorney" if he/she has already been admitted to a state or territorial bar. However, engineers, scientists and any other science-based majors, as well as law students and law graduates who are not admitted to a bar, will be labeled as "patent agents" since they cannot give legal advice nor represent clients in court. The latest exam result statistics are for the 2014 fiscal year, when 2,799 exams were administered with 42.8% resulting
