• Be in one of the following categories that
receive copyright protection under federal statute:
1. literary works
2. musical works, including any accompanying words
3. dramatic works, including any accompanying music
4. pantomimes and choreographic works
5. pictorial, graphic, and sculptural works
6. motion pictures and other audiovisual works
7. sound recordings
8. architectural works
The category of "literary works" includes
computer programs, catalogs, and other works that have nothing to
with literature. It covers "works, other than audiovisual works,
expressed in words, numbers, or other verbal or numerical symbols
or indicia . . . "
• Be an "original work of authorship."
This means there must be some small degree of originality involved.
For example, a list of facts is not likely to be protected by copyright
unless there is some original arrangement to the list. Thus, a database
of facts, absent original selection and arrangement, will usually
be excluded from copyright protection. The U.S. Supreme Court held
that an alphabetical listing of persons in the white pages of a phone
book is not protected by copyright.
• Be "fixed in a tangible medium of expression."
Works must be preserved in some way, such as written on paper, engraved
in stone, recorded on electromagnetic disk or tape, etched by laser
in a compact disk, or even temporarily stored in the random access
memory of a computer. A rainbow in the sky and, more to the point,
a speech that is not written or recorded, has no copyright protection.
• Not be an "idea, procedure, process,
system, method of operation, concept, principle, or discover, regardless
of the form in which it is described, explained, illustrated, or embodied"
in a copyrighted work. Copyright applies to the expression of ideas,
not the ideas themselves. Thus, the general plot for a play may be
used in many variations without infringing copyright, but the written
words of the same play are likely to be protected by copyright. (Note,
however, that one may not create works derived from a copyrighted
work, such as translations and adaptations, without respecting the
copyright of the original.) A process, machine, etc., may be protected
by patent law as opposed to copyright law.
• Not be a work produced by a U.S. government
employee in the scope of employment. Such works are in the public
domain.
• Not be a short phrase or title. Copyright
requires more length, although a distinctive phrase or mark could
fall under trademark protection.
• Not be a work the author has expressly made
available for unrestricted copyright, distribution, etc. Such works
have been effectively dedicated to the public domain.
• Not be a work whose copyright has expired.
Copyright has a limited term by law. Typically, it is 70 years plus
the life of the author, but there are numerous other terms. See When
Works Pass Into the Public Domain for a table showing when copyright
expires for various types of works.
