What Are The Three Exceptions To Copyright?

Most people assume copyright protection is absolute. It isn’t. The law carves out specific situations where using someone else’s work is perfectly legal. Knowing these exceptions can save you from an unnecessary legal battle. It can also help you understand when your own rights may not be as airtight as you think. So, what are the three exceptions to copyright? They are fair use, public domain, and U.S. government works.

Let’s break each one down.

1. Fair Use

Fair use is the most well-known exception. It allows limited use of copyrighted material without permission.

But here’s the thing: fair use is not a free pass. Courts decide fair use on a case-by-case basis. They weigh four key factors:

• The purpose and character of the use. Is it commercial or educational? Transformative uses (commentary, parody, criticism) get more protection.
• The nature of the original work. Factual works get less protection than creative ones.
• The amount used. Using a small portion weighs in your favor. Using the “heart” of a work, even a small portion, can weigh against you.
• The effect on the market. If your use harms the original creator’s ability to profit, it hurts your fair use claim.

Common examples of fair use include news reporting, criticism, satire, teaching, and research.

The U.S. Copyright Office has a helpful overview of fair use principles for anyone wanting to go deeper.

Fair use disputes are genuinely tricky. What seems obvious to you may look very different to a judge.

2. Public Domain

Work in the public domain is free for anyone to use. No permission needed. No licensing fees.

How does a work enter the public domain? There are a few ways:

• Copyright expires. In the United States, copyright lasts for the life of the author plus 70 years. After that, the work becomes public domain.
• The creator dedicates it. Some creators voluntarily release their work into the public domain.
• The work was never eligible. Titles, slogans, and short phrases, for example, cannot be copyrighted.

Classic literature, early films, and older music recordings often fall into this category. Shakespeare’s plays, early 20th-century photographs, and works published before 1928 are generally public domain in the U.S.

But be careful. A new edition of a public domain book may contain additions that ARE protected. A newly recorded version of an old song can hold its own copyright. Context matters a lot here.

3. U.S. Government Works

Works created by the U.S. federal government are not eligible for copyright protection. These are free for public use by default.

This includes things like federal court opinions, congressional reports, government agency publications, and many official photographs.

The logic behind this rule is straightforward. Taxpayers fund the federal government. The output of that government should be publicly accessible.

There are a few important nuances, though. State and local government works do not always follow this same rule. And the federal government can hold copyright in works it receives by assignment or license from a private creator.

So just because it came from a .gov website does not automatically mean it is free to use without restriction.
