license does not confer any possessory interest in the licensee, in the event of a sale of the property, the license is terminated and cannot be enforced against the new owners of that property. Moreover, the death of either the licensee or licensor will terminate the agreement. Remedies If a license is revocable at will by the licensor, courts will be unable to grant specific performance in favor of the licensee. A licensee would be unsuccessful in bringing forcible entry claims or a detainer proceeding because the licensee was never granted any possory interest. The Licensee would also not be able to recover damages for money spent unless they are able to show detrimental reliance on the license. In certain cases, however, licenses can be made irrevocable, and specific performance may be granted. Where a license is made with a set term period and valid consideration is transferred, revocation of the license prior to the terms expiration may raise breach of contract claims that could provide damages against the licensor. Furthermore, once the licensor terminates or revokes the license, notice is statutorily required prior to the commencement of any special proceeding to recover possession of the property (e.g., in NY that requirement is 10 days). Mass licensing of software Mass distributed software is used by individuals on personal computers under license from the developer of that software. Such license is typically included in a more extensive end-user license agreement (EULA) entered into upon the installation of that software on a computer. Typically, a license is associated with a unique code, that when approved grants the end user access to the software in question. Under a typical end-user license agreement, the user may install the software on a limited number of computers. The enforceability of end-user license agreements is sometimes questioned. As of 2020, there are various ways to license software with different kinds of licensing models, which allow software vendors to profit from their product offerings in flexible ways. Patent licensing Like other intellectual property, patent owners may grant permission to others to engage in conduct that would otherwise be within the scope of a patent. For example, a patent owner may authorize a licensee to make, use, sell, offer for sale, or import a patented product. Such agreements are typically referred to as a patent license agreement or a covenant not to sue. These agreements can last for a
