Copyright is a form of protection grounded in the U.S. Constitution and granted by law for original works of authorship fixed in a tangible medium of expression. This protection covers both published and unpublished works, It is illegal for anyone to violate any of the rights provided by the copyright law to the owner of copyright. See Copyright Basics for more information.
Literary works, musical works, including any accompanying words; dramatic works, including any accompanying music; pantomimes and choreographic works, artistic works, including cartoons and comic strips; pictorial, graphic, sculptural works, motion pictures and other audiovisual works, sound recordings, architectural works
Note: These categories should be viewed broadly. For example, computer programs and most “compilations” may be registered as “literary works”; maps and architectural plans may be registered as “pictorial, graphic, and sculptural works.
Works which are not original, or which are not tangibly fixed. For example, titles, slogans, or short phrases are not protected by copyright law, but in some cases these things may be protected as trademark law. Ideas, names, plans, methods, pseudonyms, systems, facts are not protected by copyright. In some circumstances, an artistic logo or a name may also be protected as a trademark. Blank forms and similar works designed to record rather than to convey information are not protected by copyright law. Works by the U.S. government are not eligible for copyright protection.

Some brand names, trade names, slogans, and phrases may be entitled to protection under laws relating to unfair competition, or they may be entitled to protection and registration under the provisions of state or federal trademark laws. The federal trademark statute covers trademarks and service marks—words, phrases, symbols, or designs that distinguish the goods or services of one party from those of another. The Copyright Office has no role in these matters.
