Assuming I create some artwork. Now I create copies or derivatives of that artwork (which, if they were made by someone else, would infringe on my copyright) and sell some and keep others.
Now, at a later date, I transfer all rights associated with the copyright to someone else.
Does that in any way affect copies I've already sold (or their owners) in any way? Can the new owner of the rights in anyway prevent the owners of the copies from reselling their copies?
As the owner of some of the copies/derivatives that have been created before transferring the rights, am I still allowed to use/sell these copies?
Assuming all parties are US citizen located in the US.
