Okla. Stat. tit. 18, § 18-584: Use of society name exclusive

No person, society, association or corporation shall assume,

adopt or use the name of a humane, fraternal or charitable

organization, incorporated under the laws of this or of any other

state of the United States, or a name so nearly resembling the name

of such incorporated organization as to be a colorable imitation

thereof, or calculated to deceive persons not members, with respect

to such corporation. In all cases where two or more of such

societies, associations or corporations claim the right to the same

name, or to names substantially similar as above provided, the

organization which was first organized and used the name, and first

became incorporated under the laws of the United States or of any

state of the Union, shall be entitled in this state to the prior and

exclusive use of such name, and the rights of such societies,

associations or corporations, and of their individual members shall

be fixed and determined accordingly.
