One of the super-duper fun things to do in Fortnite is using the emotes, many of which are little endgame dances for when you somehow manage to outlive all your 12-year-old opponents. These dances can be earned both through play and microtransaction packs. But now, Epic is being sued for copyright infringement by several of these dance's creators. We've got rapper 2 Milly, the flossing Backpack Kid, and Fresh Prince Of Bel-Air star Alonzo Riviera, the popularizer of the world-acclaimed "Carlton."
Now, the Copyright Act of 1974 is actually pretty clear on this matter, and distinguishes between dance moves you can and can't copyright. In the same way that a musical note is just a sound, a dance step is just movement, and you can't own movement, because that's how we get to the store and buy food. Choreography is complex and documentable, with its own form of annotation like sheet music. Meanwhile, if you were to write down a dance move, it'd look less like an artful story through movement and more like instructions on how to throw a fireball in Street Fighter.
