II.B.2. Special Provisions
The special provisions for compilations and derivative works are contained in Section 103:
(a) The subject matter of copyright as specified by section 102 includes compilations and derivative works, but protection for a work employing preexisting material in which copyright subsists does not extend to any part of the work in which such material has been used unlawfully.
(b) The copyright in a compilation or derivative work extends only to the material contributed by the author of such work, as distinguished from the preexisting material employed in the work, and does not imply any exclusive right in the preexisting material. The copyright in such work is independent of, and does not affect or enlarge the scope, duration, ownership, or subsistence of, any copyright protection in the preexisting material.
In the legislative history, the drafters explained those provisions:
The most important point here is one that is commonly misunderstood today: copyright in a “new version” covers only the material added by the later author, and has no effect one way or the other on the copyright or public domain status of the preexisting material. . . .
The second part of the sentence that makes up section 103(a) deals with the status of a compilation or derivative work unlawfully employing preexisting copyrighted material. In providing that protection does not extend to “any part of the work in which such material has been used unlawfully,” the bill prevents an infringer from benefiting, through copyright protection, from committing an unlawful act, but preserves protection for those parts of the work that do not employ the preexisting work. Thus, an unauthorized translation of a novel could not be copyrighted at all, but the owner of copyright in an anthology of poetry could sue someone who infringed the whole anthology, even though the infringer proves that publication of one of the poems was unauthorized. Under this provision, copyright could be obtained as long as the use of the preexisting work was not “unlawful,” even though the consent of the copyright owner had not been obtained. For instance, the unauthorized reproduction of a work might be “lawful” under the doctrine of fair use or an applicable foreign law, and if so the work incorporating it could be copyrighted.
Many works are protected by a number of copyrights. For example, when a movie is made from a best-selling novel, the material that comes from that novel is protected by the novel’s original copyright. The screenplay is a derivative work of the novel and has its own copyright covering its original aspects. (For example, added dialogue or the instructions for the staging of a scene.) Both are literary works. The actual movie, an audiovisual work, has its own copyright covering the things that are original to the movie and not in the screenplay, such as the director’s particular arrangement for a shot. The musical score of the movie also has its own copyright. In each case, the copyright covers only what is original to that particular work.
