Copyright

The doctrine of fair use has developed through a substantial number of court decisions over the years and has been codified in section 107 of the copyright law.

Section 107 contains a list of the various purposes for which the reproduction of a particular work may be considered fair, such as criticism, comment, news reporting, teaching, scholarship, and research. Section 107 also sets out four factors to be considered in determining whether or not a particular use is fair.

1. The purpose and character of the use, including whether such use is of commercial nature or is for nonprofit educational purposes

2. The nature of the copyrighted work

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

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

The distinction between what is fair use and what is infringement in a particular case will not always be clear or easily defined.
