Patent and Trademark Practitioners (Intellectual Property (IP) Agent/Attorney/Barrister/Lawyer)

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.

注册专利执业人员（Registered patent practitioners）指通过美国专利商标局（USPTO）注册考试并满足相关资质要求，可在美国专利商标局代理专利申请人事务的人员。商标执业人员（Trademark practitioners）是指在任一州的最高法院律师协会中保持良好执业状态的活跃在职律师。注意：由于商标律师无需向USPTO申请商标法执业注册，USPTO并未维护商标律师名册。专攻商标法的律师名录可通过电话黄页查询，或联系当地律师协会获取。多数州的律师协会官网提供可检索的律师在线登记系统，且诸多律师协会设有律师推荐服务项目。
