When issued by a public authority, a cease and desist letter, being "a warning of impending judicial enforcement", is most appropriately called a "cease and desist order". </P> <P> Although cease and desist letters are not exclusively used in the area of intellectual property, such letters "are frequently utilized in disputes concerning intellectual property and represent an important feature of the intellectual property law landscape". The holder of an intellectual property right such as a copyrighted work, a trademark, or a patent, may send the cease and desist letter to inform a third party "of the right holders' rights, identity, and intentions to enforce the rights". The letter may merely contain a licensing offer or may be an explicit threat of a lawsuit . A cease and desist letter often triggers licensing negotiations, and is a frequent first step towards litigation . </P>
