Trademarks

“Iyengar Yoga” Is Trademarked in the U.S.

In accordance with his lifetime contribution to the art, science, and philosophy of yoga, B.K.S. Iyengar pursued trademark protection so that yoga associated with his name is taught only by a Certified Iyengar Yoga Teacher (CIYT). As of August 14, 2007, the name “Iyengar” associated with yoga has been registered as a trademark and is protected in the United States in connection with Iyengar Yoga taught solely by CIYTs.

Only CIYTs in good standing are licensed and permitted to use “Iyengar Yoga” to describe their yoga programs or classes. The term “in good standing” is determined exclusively by B.K.S. Iyengar and means that the certified teacher:

  • Teaches in the method set forth by B.K.S. Iyengar, without mixing methods.
  • Pays annual dues to their regional association, pays the annual Certification Mark fee, and has signed the annual Certification Mark agreement.
  • Receives continuing education from RIMYI or from an Intermediate or Advanced Iyengar teacher or teachers.

After passing the Level 1 assessment, a teacher is considered a CIYT, and only then can their classes be identified as Iyengar Yoga classes. Non-certified teachers may not use or advertise the terms “Iyengar Yoga,” “Iyengar style, “or “Iyengar influenced,” or similar language that could imply that they are certified or qualified to teach Iyengar Yoga in classes, teacher trainings, workshops, etc. They may not use the name “Iyengar” in any form of business communication or advertising or for any financial gain. They may, however, indicate that they have taken classes with Iyengar Yoga teachers. Additional information regarding the appropriate use of Mr. Iyengar’s name is available in the IYNAUS Certification Manual.

Improper Use of The Trademark

IYNAUS logoThe trademark was applied for at the request of B.K.S. Iyengar and is maintained by IYNAUS to protect Mr. Iyengar's teachings and the professional integrity of CIYTs. It represents years of study, practice, and strict dedication to the Iyengar method.

IYNAUS, a primarily volunteer organization, does not have the capacity to regularly seek out improper use of the term "Iyengar Yoga." If you become aware of improper use of the Iyengar Yoga Trademark, please send a link to the website at issue or other evidence of potential misuse in an email to contact@iynaus.org.

Thank you for helping IYNAUS protect the integrity of certification and the right to use the Certification Mark.

Certified Iyengar Yoga Teachers (CIYTs)

Becoming a Certified Iyengar Yoga Teacher (CIYT™) begins with long-term, dedicated practice. One is a student of Iyengar Yoga before becoming a teacher. For CIYTs, earning a Certification Mark demonstrates their commitment to maintaining the purity, excellence, and high standards of Iyengar Yoga.

CIYTs commit to teaching the method of yoga set forth by B.K.S. Iyengar without mixing in other styles or disciplines. CIYTs continue their annual training with a mentor and/or attend classes at the Ramamani Iyengar Memorial Yoga Institute in Pune, India.

IYNAUS assesses Iyengar Yoga teachers in the United States, while RIMYI provides certificates. The assessment process that leads to certification has been designed and refined over many years under the guidance of B.K.S. Iyengar, Geeta Iyengar, Prashant Iyengar, and Abhijata Iyengar.

In July 2020, RIMYI updated the guidelines for assessing and certifying teachers. Please find the Certification and Assessment Guidelines here.
