What Is Copyright Law? Rights, Fair Use, and Infringement

What Is Copyright?

Copyright is a form of intellectual property law that grants creators of original works exclusive legal rights to control how their works are used, reproduced, distributed, displayed, performed, and adapted. It covers a vast range of creative output: literary works, music, films, photographs, software, architectural designs, paintings, and even choreography.

Copyright arises automatically at the moment an original work is fixed in a tangible form — when words are written down, a song is recorded, or code is saved to a file. No registration, publication, or copyright notice is required for protection to exist, though registration provides important legal advantages in U.S. courts.

What Copyright Protects (and Does Not Protect)

Copyright protects the expression of ideas, not the ideas themselves. This distinction — known as the idea-expression dichotomy — is foundational to copyright law.

Facts, names, titles, short phrases, slogans, and government works (in the U.S.) are not copyrightable. Works must meet a minimum threshold of originality — though this threshold is low, requiring only independent creation and at least a modicum of creativity.

Exclusive Rights of Copyright Holders

The owner of a copyright holds a bundle of exclusive rights under U.S. law (17 U.S.C. § 106):

• Reproduction: The right to make copies
• Distribution: The right to sell or otherwise distribute copies
• Adaptation (derivative works): The right to create works based on the original (e.g., translations, adaptations, sequels)
• Public performance: The right to perform the work publicly (music, drama, films)
• Public display: The right to display the work publicly
• Digital audio transmission: The right to transmit sound recordings digitally

Copyright holders may transfer any or all of these rights to others through licensing agreements or outright assignment.

Duration of Copyright

How long copyright lasts depends on when and where the work was created.

International copyright terms vary; the European Union also applies a life-plus-70-years standard for most works. Once copyright expires, the work enters the public domain, where anyone may freely use it.

Fair Use

Fair use is a legal doctrine in U.S. copyright law that allows limited use of copyrighted material without permission under certain circumstances. Courts evaluate four factors when determining whether a use is fair:

1. Purpose and character of the use: Transformative uses (commentary, criticism, parody, education) weigh in favor of fair use; commercial use weighs against
2. Nature of the copyrighted work: Factual works receive less protection than highly creative works
3. Amount and substantiality: Using a small portion generally favors fair use, but even a small excerpt can infringe if it is the "heart" of the work
4. Effect on the market: The most important factor — whether the use harms the market for or value of the original

Fair use determinations are inherently fact-specific; no mechanical formula applies. Academic research, news reporting, commentary, and parody are classic examples of fair use, but none are automatically protected — each case depends on context.

Copyright Infringement and Remedies

Copyright infringement occurs when someone exercises one of the copyright holder's exclusive rights without permission and without a valid defense such as fair use. Remedies in U.S. law include:

• Actual damages: The copyright holder's lost profits plus the infringer's profits attributable to the infringement
• Statutory damages: $750–$30,000 per work infringed (up to $150,000 for willful infringement), available if the work was registered before infringement
• Injunctions: Court orders requiring the infringer to stop the infringing activity
• Attorney's fees: Available for registered works

The Digital Millennium Copyright Act (DMCA) of 1998 added specific rules for online infringement, including the notice-and-takedown system that allows rights holders to request removal of infringing content from online platforms.
