License

"A license (American English) or licence (British English) is an official permission or permit to do, use, or own something (as well as the document of that permission or permit).

A license is granted by a party to another party as an element of an agreement between those parties. In the case of a license issued by a government, the license is obtained by applying for it. In the case of a private party, it is by a specific agreement, usually in writing (such as a lease or other contract). The simplest definition is "A license is a promise not to sue," because, with the exception of a marriage license (which merely grants official recognition of the relationship between the two people), a license either permits the licensed party to engage in an activity which is illegal, and subject to prosecution, without the license (e.g. fishing, driving an automobile, or operating a broadcast radio or television station), or it permits the licensed party to do something that would violate the rights of the licensing party (e.g. make copies of a copyrighted work), which, without the license, the licensed party could be sued, civilly, criminally, or both." - (en.wikipedia.org 06.01.2021)
