 IA argues, however, that this infringement is excused by the doctrine of fair use. This doctrine allows some unauthorized uses of copyrighted works "to fulfill copyright's very purpose, '[t]o promote the Progress of Science and useful Arts., 510 U.S. 569, 575 (1994). While rooted in the common law, fair use is a statutory exception to copyright infringement. The Copyright Act of 1976 provides that "the fair use of a copyrighted work" for "purposes such as criticism, comment, news reporting, teaching (including multiple copies for classroom use), scholarship, or research, is not an infringement of copyright." § 107.

"In determining whether the use made of a work in any particular case is a fair use," the Copyright Act directs courts to consider the following factors: "(1) the purpose and character of the use, including whether such use is of a 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; and

(4) the effect of the use upon the potential market for or value of the copyrighted work."

17 U.S.C. § 107.

The four factors are not exclusive, but each must be considered in a "case-by-case analysis," with the results "weighed together[] in light of the purposes of copyright."
