Letters Patent (or Patent Writ) from the Latin patens,patentis = open, are letters bearing the great seal of the State which the King sent"open" to the local Parliaments. They are the opposite of "Lettres de Cachet", letters sealed by the King and which carried an order from him, generally one for the imprisonment of an eminent subject. (Larousse)
