A Copyright License Agreement is an official agreement between two parties that outlines the terms and conditions under which a copyright holder (the licensor) permits or grants another party (the licensee) access to use their original work. This type of contract sets out how, when, and where the intellectual property can be used. It also determines how any potential profits due to the use of the work will be shared. By entering into this agreement, both parties are committing to upholding the rules outlined in it – making it a vital part of any business relationship.
