1304.07 Character of the Mark
A collective membership mark may be a letter or letters, a word or words, a design alone, a name or nickname, or other matter that identifies the collective organization or indicates its purpose. A membership mark may, but need not, include the term "member" or the equivalent.
In addition to being printed (the most common form), a membership mark may consist of an object, such as a flag, or may be a part of articles of jewelry, such as pins or rings. See TMEP §§1304.03 and 1304.09(c) regarding use of membership marks and acceptable specimens.
