Letters patent (Latin : litterae patentes) (always in the plural) are a type of legal instrument in the form of a published written order issued by a monarch, president or other head of state, generally granting an office, right, monopoly, title or status to a person or corporation. Letters patent can be used for the creation of corporations or government offices, or for granting city status or a coat of arms. Letters patent are issued for the appointment of representatives of the Crown, such as governors and governors-general of Commonwealth realms, as well as appointing a Royal Commission. In the United Kingdom they are also issued for the creation of peers of the realm.


A particular form of letters patent has evolved into the modern intellectual property patent (referred to as a utility patent or design patent in United States patent law) granting exclusive rights in an invention or design. In this case it is essential that the written grant should be in the form of a public document so other inventors can consult it both to avoid infringement (while the patent remains in force) and to understand how to put it into practical use (once the patent rights expire). In the Holy Roman Empire, Austrian Empire, and Austria-Hungary, imperial patent was also the highest form of generally binding legal regulations, e.g. Patent of Toleration, Serfdom Patent etc.

The opposite of letters patent are letters close (Latin : litterae clausae), which are personal in nature and sealed so that only the recipient can read their contents. Letters patent are thus comparable to other kinds of open letter in that their audience is wide. It is not clear how the contents of letters patent became widely published before collection by the addressee, for example whether they were left after sealing by the king for inspection during a certain period by courtiers in a royal palace, who would disseminate the contents back to the gentry in the shires through normal conversation and social intercourse. Today, for example, it is a convention for the British prime minister to announce that they have left a document they wish to enter the public domain "in the library of the House of Commons", where it may be freely perused by all members of parliament.


Letters patent are so named from the Latin verb pateo, to lie open, exposed, accessible. [1] The originator's seal was attached pendent from the document, so that it did not have to be broken in order for the document to be read.

They are called "letters" (plural) from their Latin name litterae patentes, used by medieval and later scribes when the documents were written in Latin. This loanword preserves the collective plural "letters" (litterae) that the Latin language uses to denote a message as opposed to a single alphabet letter (littera). [2]


Letters patent are a form of open or public proclamation [3] and a vestigial exercise of extra-parliamentary power by a monarch or president. Prior to the establishment of Parliament, the monarch ruled absolutely by the issuing of his personal written orders, open or closed.[ citation needed ]

They can thus be contrasted with the Act of Parliament, which is in effect a written order by Parliament involving assent by the monarch in conjunction with its members. No explicit government approval is contained within letters patent, only the seal or signature of the monarch.[ citation needed ]

Parliament today tolerates only a very narrow exercise of the royal prerogative by issuance of letters patent, and such documents are issued with prior informal government approval, or indeed are now generated by government itself with the monarch's seal affixed as a mere formality. In their original form they were simply written instructions or orders from the sovereign, whose order was law, which were made public to reinforce their effect.[ citation needed ]

For the sake of good governance, it is of little use if the sovereign appoints a person to a position of authority but does not at the same time inform those over whom such authority is to be exercised of the validity of the appointment.[ citation needed ]

According to the United Kingdom Ministry of Justice, there are 92 different types of letters patent. [4] The Patent Rolls are made up of office copies of English (and later United Kingdom) royal letters patent, which run in an almost unbroken series from 1201 to the present day, with most of those to 1625 having been published.[ citation needed ]

United Kingdom and Commonwealth realms

In the United Kingdom and other Commonwealth realms, letters patent are royal proclamations granting an office, right, title, or status to a person (and sometimes in regards to corporations and cities). Letters patent take the form of an open letter from the monarch to a subject, although this is a legal fiction and they are in fact a royal decree made under the Royal Prerogative, and are treated as statute law. [5] Letters patent do not require the consent of parliament. [6]

The primary source of letters patent in the United States are intellectual property patents and land patents, though letters patent are issued for a variety of other purposes. They function dually as public records and personal certificates.[ citation needed ]

In the United States, the forgery of letters patent granted by the President is a crime subject to fine, imprisonment up to ten years or both (18 U.S.C.   § 497). Without letters patent, a person is unable to assume an appointed office. Such an issue prompted the Marbury v. Madison suit, where William Marbury and three others petitioned the United States Supreme Court to order James Madison to deliver their letters for appointments made under the previous administration.[ citation needed ]

Form of United States letters patent

United States letters patent generally do not fit a specific form, except for the eschatocol, or formal ending:

IN TESTIMONY WHEREOF, the undersigned [public official], in accordance with [relevant law], has in the name of the United States, Caused these letters to be made Patent and the Seal of [relevant agency or government official] to be hereunto affixed.

Royal assent is the method by which a monarch formally approves an act of the legislature, either directly or through an official acting on the monarch's behalf. In some jurisdictions, royal assent is equivalent to promulgation, while in others that is a separate step. Under a modern constitutional monarchy, royal assent is considered little more than a formality. Even in nations such as the United Kingdom, Norway, the Netherlands and Liechtenstein which still, in theory, permit their monarch to withhold assent to laws, the monarch almost never does so, except in a dire political emergency or on advice of government. While the power to veto by withholding royal assent was once exercised often by European monarchs, such an occurrence has been very rare since the eighteenth century.

The royal we, majestic plural, or royal plural, is the use of a plural pronoun used by a single person who is a monarch or holds a high office to refer to themselves. A more general term for the use of a we, us, or our to refer to oneself is nosism.

The style and title of the Canadian sovereign is the formal mode of address of the monarch of Canada. The form is based on those that were inherited from the United Kingdom and France, used in the colonies to refer to the reigning monarch in Europe. As various Canadian territories changed ownership and then the country gradually gained independence, the style and title of the monarchs changed almost as often as the kings and queens themselves. The mode of address currently employed is a combination of a style that originates in the early 17th century and a title established by Canadian law in 1953.

In the Commonwealth realms, a Royal Style and Titles Act or a Royal Titles Act is an Act of Parliament passed in the relevant jurisdiction which defines the sovereign's formal title in that jurisdiction. The most significant of these acts is the Royal and Parliamentary Titles Act 1927 of the United Kingdom, which recognised the creation of the Irish Free State, a development that necessitated a change in King George V's title.

The Great Seal of Canada is a governmental seal used for purposes of state in Canada, being set on letters patent, proclamations and commissions, both to representatives of the monarch and for the appointment of cabinet ministers, senators, and judges. Many other officials, such as officers in the Canadian Armed Forces, receive commissions affixed with the Privy Seal, not the great seal. It is not for sealing up a document as letters close. As a de facto symbol of Canada the seal is one of the oldest and most honoured instruments of the Canadian government.

The monarchy of Antigua and Barbuda is a system of government in which a hereditary monarch is the sovereign and head of state of Antigua and Barbuda. The current Antiguan and Barbudan monarch and head of state, since the independence of Antigua and Barbuda on 1 November 1981, is the King of the United Kingdom, which currently is Charles III. As sovereign, he is the personal embodiment of the Crown of Antigua and Barbuda. Although the person of the sovereign is equally shared with 14 other independent countries within the Commonwealth of Nations, each country's monarchy is separate and legally distinct. As a result, the current monarch is officially titled King of Antigua and Barbuda and, in this capacity, he and other members of the Royal Family undertake public and private functions domestically and abroad as representatives of Antigua and Barbuda. However, the King is the only member of the Royal Family with any constitutional role.
