exslusive license – license limited to a specific scope or field, such as context, market, territory, or time. 'Exclusive' does not mean 'one and only' license granted, but only that the licensor agrees not to grant other licenses that have the same rights within the scope or field covered by the exclusive license. It may refer to a geographical area, technological application, method of production, or production of a specific product. (BusinessDictionary)

In any situation where a license is granted from one party to another, there is a licensee and a licensor. The licensee is the party that receives a license, while the licensor is the party that grants the license. For instance, if a bar owner gets a liquor license from the state where he operates his business, the owner is the licensee and the government that issued the license is the licensor.
