An equitable remedy that enjoins, i.e., prohibits someone, from doing something, such as selling infringing goods. An injunction is a presumptive remedy for infringement in most IP systems, usually coupled with damages. Courts can, but rarely issue so called mandatory injunctions – that require the recipient to do something as opposed to ordering the recipient to refrain from doing something – this is because of the difficulty in forcing persons into a course of action, or policing performance. Mandatory injunctions are also known as a “writ of mandamus,” from the Latin “we command.”
