* Both patent attorneys and patent agents are licensed to represent clients in all patent proceedings in front of the U.S. Patent and Trademark Office (USPTO). However, only attorneys may represent clients in a court of law or file suit. Restrictions on the practice of trademark and contract law also apply.
** Year of first license to practice is based on the year first admitted in any jurisdiction including the USPTO.
*** “Licensing” is the jurisdictions that licensed the attorney/agent. Patent attorneys and patent agents who have passed the USPTO bar exam are licensed to practice federally (in any state in the U.S.).
