Copyright - Works That Are Not Copyrightable

Copyright protects the expression of an idea or vision, not the idea itself. In legal terminology, this concept is called the idea-expression dichotomy, and it has been an important feature of legal reasoning related to copyright. Ideas, procedures, processes, systems, methods of operation, concepts, principles, and discoveries are not within the scope of copyright protection. Other works that are not copyrightable are words and short phrases, including slogans; blank forms for recording information (such as bank checks); and works containing no original authorship (such as standard calendars or simple phone listings).

Some works are not copyrightable because they are not fixed in a tangible medium. These include unrecorded dance choreography, and unrecorded speeches, lectures, and other vocal performances. Although typefaces are tangible, they traditionally have been regarded as lying outside of copyright protection. A dramatic character is not copyrightable.
