“Fair use is based on the belief that the public is entitled to freely use portions of copyrighted materials for purposes of commentary and criticism.”
“Violations often occur when the use is motivated primarily by a desire for commercial gain. The fact that a work is published primarily for private commercial gain weighs against a finding of fair use.”
The following are generally considered Fair Use:
- Criticism and comment — for example, quoting or excerpting a work in a review or criticism for purposes of illustration or comment.
- News reporting — for example, summarizing an address or article, with brief quotations, in a news report.
- Research and scholarship — for example, quoting a short passage in a scholarly, scientific, or technical work for illustration or clarification of the author’s observations.
- Nonprofit educational uses — for example, photocopying of limited portions of written works by teachers for classroom use.
- Parody — that is, a work that ridicules another, usually well-known, work by imitating it in a comic way.
