What is the fair use doctrine?

• A. A copyright defense allowing limited use without permission; factors include purpose, nature, amount used, and effect on market.
• B. A legal remedy requiring permission for all uses of copyrighted work.
• C. A doctrine requiring payment of royalties for any use.
• D. A rule that prohibits any use of copyrighted material.

Answer: (A)

Fair use is a copyright defense that lets someone use a protected work without permission in limited, often transformative, ways. It isn’t automatic; courts apply a four-factor test to decide if the use is allowed.

First, the purpose and character of the use matters. Uses such as criticism, commentary, news reporting, teaching, scholarship, or transformative works (like parody) are favored more than ordinary commercial copying. Second, the nature of the original work plays a role—uses of factual or published works are more likely to be fair than uses of highly creative or unpublished works. Third, the amount and substantiality of what’s used is assessed; using a small portion or less essential parts weighs in favor, while taking the core portion can weigh against. Fourth, the effect on the market for the original is crucial—uses that harm licensing opportunities or reduce the original’s market tend to be less likely to qualify as fair use.

Examples include a teacher showing a short clip for classroom discussion, a critic quoting lines in a review, or a news outlet summarizing events.

Other options misstate fair use: it isn’t a remedy that requires permission for all uses, it doesn’t require royalties for any use, and it doesn’t prohibit all use.
