A letter from Saskia Florence, a supervisory registration specialist at the US Copyright Office, to lawyer David Hecht of Ribeiro, came out this week as part of federal court documents in California.
In the correspondence, Florence wrote that the movements are "a simple dance routine".
"As such, it is not regis- terable as a choreographic work," the letter explained.
She also wrote an explanation of the choreography in which the dancer wags their hips as they step from side to side while they exaggerate their arms & # 39 ;.
Florence wrote: "This single dance pass can not be registered as a choreographic work and your registration application will be refused accordingly."
Ribeiro debuted the movements during a scene on the popular show with Will Smith.
In one episode the character of Ribeiro, Carlton Banks, plays the dance on the Tom Jones classic "It & # 39; s Not Unusual."
The choreography also helped the actor and the TV presenter to win "Dancing With the Stars".
Ribeiro and his professional dance partner, Witney Carson, were crowned champion of that competition dance show in 2014, with one of their highlights performing with the "Carlton Dance & # 39 ;.
