Exclusive license is an agreement between a trademark owner and another party that allows the other party to make certain use of the trademark. Exclusive license is provided with the understanding that the trademark owner will not permit other such uses to anyone else. Licensing of trademarks can result in the loss of the trademark unless the license contains careful controls over the licensed use. The party to whom a trademark owner grants an exclusive license to use a trademark is an exclusive licensee. The trademark owner who is licensing its trademark for exclusive use by one other company is the exclusive licensor.
