You can't copyright these short sequences of moves. This is the government copyright office doc. https://www.copyright.gov/circs/circ52.pdf "Individual movements or dance steps by themselves are not copyrightable, such as the basic waltz step, the hustle step, the grapevine, or the second position in classical ballet. The U.S. Copyright Office cannot register short dance routines consisting of only a few movements or steps with minor linear or spatial variations, even if a routine is novel or distinctive. Examples of commonplace movements or gestures that do not qualify for registration as choreographic works or pantomimes include • A set of movements whereby a group of people spell out letters with their arms • Yoga positions • A celebratory end zone dance move or athletic victory gesture" These morons just capitulated to something wherein the plaintiffs simply have no case whatsoever.
