Copyright

A guide to current copyright regulations, fair use, and the public domain.

Fair Use

"Fair use" refers to the specific uses of copyrighted material that are allowed under copyright protection without requiring permission from the copyright owner (17 U.S.C. §107).

These uses include criticism, parody, commentary, journalism, education and research.

New works of art and research are based on the works that came before, but copyright law can limit a creator's access to these works. As Judge Joseph Story noted in 1845:

“In truth, in literature, in science and in art, there are, and can be, few, if any things, which in an abstract sense, are strictly new and original throughout. Every book in literature, science, and art, borrows, and must necessarily borrow, and use much which was well known and used before.”

The fair use exemption exists for just this reason.

What's considered a fair use?

The ability to claim use of something under the fair use exemption relies on the following factors:

  • The purpose and character of the use, including whether such use is of a commercial nature or is for nonprofit educational purposes;

  • The nature of the copyrighted work;

  • The amount and substantiality of the portion used in relation to the copyrighted work as a whole; and

  • The effect of the use upon the potential market for, or value of, the copyrighted work.

Is your use fair?

Fair use tends to be decided by the courts on a case-by-case basis, so there's no single formula that will decide if a use can be considered fair or not. The Fair Use Checklist from Columbia can help you think through whether your work would be allowed under fair use.

A Fair(y) Use Tale

This short by Prof. Eric Faden of Bucknell University pokes fun at the Walt Disney Corp's stringent defense of its intellectual property by using, through the doctrine of Fair Use, short clips of Disney films for the educational purpose of explaining Fair Use.
