Between artists, fans, and athletes, there has long been a dispute over the copyrighted works of circus tricks. Many points of view are expressed in these discussions, and there is rarely a clear winner. The person who devised the technique owns it, which is the most commonly suggested approach, although this has drawbacks. It's possible that someone else will come up with the same approach without realizing that it has already been done.
Since these issues and the remedies they offer have been present for years, there have been little advancement in the efforts to address them. It's been like this up until this point.
There are plans to digitize and trademark circus tricks using the Circus NFT Collection.
