A patent license is an agreement between a patent owner (licensor) and a person or entity that wants to use or benefit from the patent (the licensee) in which the licensor grants the licensee the right to use the license in the manner and for the period of time (the term) described in the license agreement.
The licensor grants the licensee a license to use the patent in exchange for royalty payments (royalties) from the licensee—often based on a percentage of sales of the goods or services in which the licensee uses the patent.
There are different types of licenses, including exclusive licenses, nonexclusive licenses, and partially exclusive licenses. A license may also grant the licensee the right to sublicense the patent rights to other persons or entities—often when the original license is an exclusive license.
