A Letter Written by Thomas A. Edison - Chicago Patent Attorney Rich Beem

Letters patent 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 the granting of 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 patent granting exclusive rights in an invention. 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 to avoid infringement and also to understand how to "practice" the invention, i.e., put it into practical use.
