Real property licenses
A license provides one party with the authority to act on another's land, when such action would typically amount to trespass absent that license. A key distinction between licenses and leases is that a license grants the licensee a revocable non-assignable privilege to act upon the land of the licensor, without granting any possessory interest in the land. Once a license is agreed upon, the licensee may occupy the land only so far as is necessary to complete the act. Another key distinction between a license and a lease is that leases are generally required to be in writing, where the statute of frauds requires it, while licenses can be made orally.Creation
A license is generally created by an express or implied agreement. The licensor must agree to the license which can be shown in writing or the licensors acquiescence in its exercise. Furthermore, unlike many other contractual agreements, a license does not require consideration, a license can be created with or without it. Moreover, whether an agreement is held to be a “license” and not a lease will depend on three essential characteristics of a license: (1) a clause allowing the licensor to revoke “at will"; (2) the retention by the licensor of absolute control over the premises; and (3) the licensor's supplying to the licensee all of the essential services required for the licensee's permitted use of the premises.Termination
Under a pure licensing agreement, the licensor, under its terms and by common-law, can cancel the agreement at will and without cause, unless it is coupled with an interest or made irrevocable by contract. A license that has been coupled with an interest is not revocable by the licensor without exposure to liability and potential damages. In the event a license is coupled with an interest, the licensor must provide reasonable time for the licensee to remove that interest from the property prior to termination. Additionally, because a 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 specific period of time (such as 5 years) or for the entire life of the patent (''i.e.,'' until the patent expires). Patent license agreements may also be exclusive (''i.e.,'' the licensee is the only person or entity that is allowed to sell, make, use, offer to sell, or import the patented invention) or non-exclusive (''i.e.,'' the licensee is simply one of several entities who has rights under the patent). Finally, any rights given under the agreement may be limited to a particular "field of use" (''e.g.,'' a licensee may be able to practice an invention in the field of consumer electronics, but not in the field of industrial electronics). Often, patent owners will require a licensee to pay money in exchange for granting a patent license. Such payments are referred to as royalty payments and come primarily in two forms: lump sum or running royalty. A lump sum royalty involves an upfront, one-time payment, while a running royalty typically involves periodic payments (''e.g.,'' quarterly or annual) based on the number of patented products sold or imported.Trademark and brand licensing
A licensor may grant permission to a licensee to distribute products under a trademark. With such a license, the licensee may use the trademark without fear of a claim of trademark infringement by the licensor. The assignment of a license often depends on specific contractual terms. The most common terms are, that a license is only applicable for a particular geographic region, just for a certain period of time or merely for a stage in the value chain. Moreover, there are different types of fees within the trademark and brand licensing. The first form demands a fee independent of sales and profits, the second type of license fee is dependent on the productivity of the licensee. For example, McDonald's licenses their trademark such as the " Golden Arches" or the " Big Mac," but the licenses gives McDonald's a right to impose strict quality standards to their franchisees as they can take back the right to the trademark if they do not meet McDonald's standards. When a licensor grants permission to a licensee to not only distribute, but manufacture a patented product, it is known as licensed production.Artwork and character licensing
A licensor may grant a permission to a licensee to copy and distribute copyrighted works such as "art" (e.g., Thomas Kinkade's painting ''Dawn in Los Gato'') and characters (e.g.,Academia

A license to driving certain vehicles has been applied to many countries around the world. Being allowed to drive a certain vehicle requires a specific driving license, the type of license depending on the type of vehicle.Criminal law
In the United Kingdom prisoners serving a determinate sentence (a fixed time in prison) will be released prior to the completion of their full sentence "on licence". The licence is the prisoner's agreement to maintain certain conditions, such as periodic reporting in to a probation officer and only living at an approved address, in exchange for their early release. If they break the conditions of the licence, they can be "recalled" (returned to prison). Offenders serving determinate sentences are released automatically at a set point in their sentence, whereas prisoners serving indeterminate sentences (e.g.Economic theory
Patent licensing has been studied in formal economic models in the field of industrial organization. In particular, Katz and Shapiro (1986) have explored the optimal licensing strategy of a research lab selling to firms who are competitors on the product market. It turns out that (compared to the welfare-maximizing solution) the licensor's incentives to develop innovations may be excessive, while the licensor's incentives to disseminate the innovation are typically too low. Subsequently, the seminal work of Katz and Shapiro (1986) has been extended in several directions. For example, Bhattacharya, Glazer, and Sappington (1992) have taken into account that the firms acquiring licenses must make further investments in order to develop marketable products. Schmitz (2002, 2007) has shown that asymmetric information due to adverse selection or moral hazard may lead the research lab to sell more licenses than it would do under complete information. Antelo and Sampayo (2017) have studied the optimal number of licenses in a signalling model.Criticism
The provision of licenses and the agencies that mandate them are often criticised by American libertarians like Milton Friedman for creating an anticompetitive environment for occupations, which creates a barrier to entry for more qualified and skilled individuals who may not have the resources to obtain the necessary licences. According to Friedman, licenses and permits have become so burdensome due to legislation that favors the current establishment of wealthy occupants that they decrease the supply of such occupations, which raises prices for the average consumer.
