Copyright — Defense— - Affirmative Defense - First Sale is a type of legal defense to copyright infringement, which allows an individual or entity to reproduce, distribute, or perform a copyrighted work without the permission of the copyright holder. This is based on the principle of exhaustion of rights, which states that the copyright holder's rights to control the reproduction and distribution of their work are exhausted once the work has been sold or otherwise transferred by the copyright holder. There are two types of First Sale defenses: Sale of Authorized Copies, and Sale of Unauthorized Copies. The Sale of Authorized Copies allows a copyright holder to resell or otherwise transfer a copy of their work that was originally authorized by the copyright holder. The Sale of Unauthorized Copies allows an individual or entity to resell or otherwise transfer a copy of a copyrighted work that was not authorized by the copyright holder.
