There are many individual O.T.O. organizations and groups that operate outside of the formal and legal jurisdiction of the Californian nonprofit religious corporation, which also holds the exclusive copyright for the name Ordo Templi Orientis.

Ordo Templi Orientis, O.T.O., and the O.T.O. Lamen design are registered trademarks of said corporation, Ordo Templi Orientis.

There are many other organizations and groups, of course, disseminating the spiritual current of Thelema according to their Will: B.O.T.O., O.T.O.A., Typhonian O.T.O., S.O.T.O., O.T.O.F., Basileus O.T.O., Ordo Templi Occultis, etc.

Much like in the case of various A.'.A.'. groups, in reality, there is no 'One True Lineage' or 'One True Teacher' above all others - aspirants and magicians from all over the world are freely following inner Will beyond temporal human organizations/corporations and personal projections on the Thelemic spiritual current, for:

"There is no law beyond Do what thou wilt." Liber AL III-60
