A writ forbidding a person to encroach on anothers privileges; as, to sell a book which is only a colourable copy of another authors book; or to violate a patent; or to perform a play based on a novel without permission of the novelist; or to publish a book the rights of which are reserved. Injunctions are of two sortstemporary and perpetual. The first is limited till the coming on of the defendants answer; the latter is based on the merits of the case, and is of perpetual force.
