ASA Announces Successful Resolution of its Opposition Against AANA's 'Nurse Anesthesiologist'Trademark Applications
AANA has withdrawn its trademark applications to register marks incorporating the term "Nurse Anesthesiologist" thanks to ASA's legal efforts to oppose this.
In June 2024, ASA filed opposition proceedings against two AANA trademark applications, for AMERICAN ASSOCIATION OF NURSE ANESTHESIOLOGISTS (Opposition No. 91292357) and AMERICAN ASSOCIATION OF NURSE ANESTHETISTS AND NURSE ANESTHESIOLOGISTS (Opposition No. 91292329).
After nearly two years, AANA filed motions to withdraw its applications on June 29, 2026. This withdrawal means AANA's applications will be denied.
The withdrawals represent a decisive victory for ASA and an important milestone in ASA's ongoing efforts to prevent improper and inaccurate use of medical titles and to protect patient access to accurate information about their care teams.
