License - sustany/dvg GitHub Wiki

Generally, a �license� is permission granted by a qualified authority permitting a�licensee�to do something that would otherwise be prohibited. �License� may also refer to a physical document granting such permission, sometimes referred to as a�permit. Licenses may have territorial and/or time limits and can be�revoked�or�forfeited.��

• Permissions granted by a license are limited by the�licensor�s�power to confer such permissions. For example, in�Gibbons v. Ogden�the�Supreme Court�ruled that a license granted by New York state giving Ogden exclusive use of a water route was void because New York lacked the power to regulate�interstate commerce.
• Licenses may be granted by�public�or private entities. Common examples of public licenses include�marriage licenses, professional licenses,�business licenses, and licenses to drive. Examples of private licenses include licenses to use�land�or�intellectual property�owned by another.

With respect to�real property, a �license� is permission to enter or use land or�property�owned by another in a manner that would otherwise constitute a�trespass. License to use or enter another�s land may be either�express�or�implied.

In intellectual property (�IP�) law, licenses allow individuals and entities to use�patents,�trademarks, and creative works owned by others without�infringing�on the owners� property rights. IP owners have the right to exclude others from using their property as conferred by statutes such as�35 U.S.C. � 154. When IP owners license use of their IP to others, they��effectively agree to forfeit their right to exclude the licensees from using the IP for a typically limited amount of time. IP owners benefit from licensing because they maintain ownership over their IP while profiting from a licensee�s use of their IP. IP licenses are usually formed�contractually�as license agreements with fixed terms, and owners usually profit from�royalties�paid by the licensee in exchange for use of the IP. IP licensing is intended to reward innovators while�incentivizing�release of the IP into the public market.
