A useful article is an object having an intrinsic utilitar¡an function that is not merely to portray the appearance of the article or to convey information. Examples are clothing, furniture, machinery, dinnerware, and lighting fixtures. An article that is normally part of a useful article may itself be a useful article, for example, an ornamental wheel cover on a vehicle.
Copyright does not protect the mechanical or utilitarian aspects of such works of craftsmanship. It may, however, protect any pictorial, graphic, or sculptural authorship that can be identified separately from the utilitarian aspects of an object. Thus, a useful article may have both copyrightable and uncopyrightable features. For example, a carving on the back of a chair or a floral relief design on silver flatware could be protected by copyright, but the design of the chair or flatware itself could not.
Some designs of useful articles may qualify for protection under the federal patent law. For further information, contact the U.S. Patent and Trademark Office, P.O.

The automated information line is (571) 272-1000.
Copyright in a work that portrays a useful article extends only to the artistic expression of the author of the pictorial, graphic, or sculptural work. It does not extend to the design of the article that is portrayed. For example, a drawing or photograph of an automobile or a dress design may be copyrighted, but that does not give the artist or photographer the exclusive right to make automobiles or dresses of the same design.
