A valid contract in which a copyright owner authorizes another person or entity (called the licensee) to exclusively exercise one or more of the rights (or portion of such rights) that belong to the copyright owner under the copyright.

A legal claim placed on real estate by someone who is owed money for labor, services or supplies contributed to the property for the purpose of improving it. Typical lien claimants are general contractors, subcontractors and suppliers of building materials. A mechanics' lien claimant can sue to have the real estate sold at auction and recover the debt from the proceeds. Because property with a lien on it cannot be easily sold until the lien is satisfied (paid off), owners have a great incentive to pay their bills.

Personal property that has no physical existence, such as stocks, bonds, bank notes, trade secrets, patents, copyrights and trademarks. Such 'untouchable' items may be represented by a certificate or license that fixes or approximates the value, but others (such as the goodwill or reputation of a business) are not easily valued or embodied in any instrument. Compare tangible property.

To 'sign' a contract electronically, a person may be asked to click an 'I Accept' button or use a 'key' to encrypt (scramble) information that uniquely identifies the signer using a method called Public Key Infrastructure (PKI). Electronic signatures are as binding as those in ink.

The act of changing a written contract when one of the parties can prove that the actual agreement was different than what's written down. The changes are usually made by a court when both parties overlooked a mistake in the document, or when one party has deceived the other.
