Copyright law protects the creative works you produce automatically — the moment you write a story, photograph a scene, or compose a song, you own a copyright. But many people are unsure of exactly what that protection covers, how long it lasts, and when the law allows others to use your work without permission. This guide breaks it all down in plain language.
What Copyright Protects
Copyright protects original works of authorship that are fixed in a tangible medium of expression. "Original" means the work reflects at least a minimal degree of creativity and was independently created by the author — not copied from someone else. "Fixed in a tangible medium" means the work is recorded in some permanent form: written on paper, saved to a hard drive, recorded on tape, or painted on canvas.
Protected categories include literary works (books, articles, software code), musical compositions and sound recordings, dramatic works and screenplays, choreography, pictorial and graphic works, sculptures and architectural works, and audiovisual works including films and video games.
Protection is automatic at the moment of creation — you do not need to register, publish, or place a copyright notice on the work, though each of those steps carries benefits discussed below.
What Copyright Does NOT Protect
Understanding the limits of copyright is just as important as understanding what it covers:
- Ideas, concepts, and methods: Copyright protects the specific expression of an idea, not the idea itself. The idea for a time-travel story is free for anyone to use; the specific screenplay you wrote is not.
- Facts and data: Raw facts are not copyrightable. A phone book listing names and numbers in alphabetical order contains no creative expression and receives no protection (Feist Publications v. Rural Telephone Service, 1991).
- Titles, names, short phrases, and slogans: "Just Do It" is a trademark, not a copyright. Titles and names generally receive no copyright protection, though trademark law may apply.
- Works in the public domain: Works whose copyright has expired, works published before 1928, and most U.S. federal government publications are freely usable by everyone.
- Government works: Works created by federal government employees as part of their official duties are not protected by copyright and are in the public domain from the moment of creation.
- Useful articles: The design of a useful object (like a lamp) is not protected unless it contains separable artistic elements.
How Long Does Copyright Last?
Copyright duration varies depending on when and how the work was created:
- Works created on or after January 1, 1978: Copyright lasts for the life of the author plus 70 years. For joint works, the term runs 70 years after the death of the last surviving author.
- Works for hire and anonymous works: Protected for 95 years from the date of first publication or 120 years from the year of creation, whichever expires first.
- Works published before 1978: Complex rules apply depending on when the work was published, whether it carried a notice, and whether the copyright was renewed. Works published before January 1, 1928, are in the public domain in the United States.
When copyright expires, the work enters the public domain and can be used freely by anyone for any purpose.
Why Register Your Copyright?
While copyright exists automatically, registration with the U.S. Copyright Office (copyright.gov) provides critical legal benefits:
- Required to file a lawsuit: For works of U.S. origin, you must register before you can sue for infringement in federal court. Without registration, you have a copyright but no ability to enforce it in court.
- Statutory damages and attorney's fees: If you registered before the infringement occurred (or within three months of publication), you can elect statutory damages of $750 to $30,000 per work — up to $150,000 for willful infringement — without having to prove actual damages. You may also recover attorney's fees.
- Public record: Registration creates a public record of your ownership, making it easier to license or transfer rights.
- Customs recordation: You can record your registration with U.S. Customs to block importation of infringing goods.
Registration costs $45–$65 for most online filings through the Copyright Office. It is money well spent for any commercially valuable work.
The Fair Use Doctrine
Fair use (17 U.S.C. § 107) is a legal defense that allows the use of copyrighted material without permission in certain circumstances. Courts analyze four factors — no single factor is decisive, and courts look at the overall picture:
Purpose & Character
Is the use transformative (commentary, parody, education, news) or merely reproducing the work for commercial gain?
Nature of the Work
Using factual works is more likely fair use than using highly creative works like novels or music.
Amount Used
Using a small portion weighs toward fair use, but taking the "heart" of a work can defeat fair use even if brief.
Market Effect
Does the use harm the potential market for the original or its licensed uses? This is often the most important factor.
Common examples of fair use include criticism and commentary (quoting a book to review it), parody, news reporting, scholarship and research, and classroom teaching. Fair use is a defense, not a right — you can only assert it after being sued, and courts decide case by case.
DMCA Takedowns and Counter-Notices
The Digital Millennium Copyright Act (DMCA) created a "notice and takedown" system that allows copyright owners to request removal of infringing content from online platforms. Here is how it works:
Sending a Takedown Notice
A valid DMCA takedown notice must identify the copyrighted work, identify the infringing content and where it is located, include a statement that the use is not authorized, include a statement of good faith belief, and include the complaining party's contact information and signature. The platform must "expeditiously" remove the content or lose its safe harbor protection from liability.
Filing a Counter-Notice
If your content was wrongly removed, you can file a counter-notice stating under penalty of perjury that you have a good faith belief the content was removed by mistake (for example, because it is your original work or it qualifies as fair use). The platform must restore the content within 10–14 business days unless the original claimant files a federal lawsuit.
