Registered patent practitioners are individuals who have passed the USPTO's registration exam and met the qualifications to represent patent applicants before the USPTO.

Trademark practitioners are attorneys who are active members in good standing of the bar of the highest court of any State.

NOTE: Because Trademark attorneys need not apply for registration to practice trademark law before the USPTO, the USPTO does not maintain a roster of trademark attorneys. The names of attorneys who specialize in trademark law may be found in the telephone yellow pages, or by contacting a local bar association. Most state bar websites offer a searchable online registry of their attorneys, and many bar associations operate attorney referral service programs.
