An Exclusive Copyright License Agreement is a legal document that grants exclusive permission to reproduce, modify, publish, and market a work. It’s an agreement between the copyright holder, or the creator of an original work, and the person or entity that wishes to use it. With an exclusive license, the grantee has exclusive rights to use the copyrighted material in any way they wish – including adaptation, reproduction, distribution, and display. This means no one else may use the material without permission from the grantee, providing them with protection against competitors.
