exclusive license
In the context of copyright licensing, a license which grants certain permissions exclusively to a single license holder.
For example, an illustrator might grant an author an exclusive license to use a particular image on their book cover. Because the license is exclusive, no other person can obtain permission to use the same image.
As another example, an author might grant a vendor an exclusive license to sell their book for a certain period of time, in exchange for additional promotion or a higher percentage of the sales revenue.
