Key points
- U.S. copyright protection requires human authorship. Material generated entirely by AI is generally not protected.
- Writing prompts, even detailed ones, does not ordinarily make you the author of the AI's output.
- AI-assisted works can be protected to the extent they contain human-authored expression, such as original text, creative modifications, or an original selection and arrangement.
- When registering, applicants should disclose AI-generated material that is more than minimal and claim only the human-authored portions.
The human authorship requirement
The Copyright Act protects "original works of authorship." The U.S. Copyright Office and federal courts have long read this to require a human author. The Copyright Office applies that requirement to generative AI in its registration guidance and in its 2025 report on the copyrightability of AI-generated material, and a federal appeals court affirmed in 2025 that a work generated autonomously by an AI system, with no human author, could not be registered.
The practical result: if an AI system determines the expressive elements of a work, those elements are generally not protected by U.S. copyright, regardless of how valuable the output is to your business.
Why prompts usually aren't enough
Many people assume that writing a careful prompt makes them the author of what comes back. Under current Copyright Office guidance, it ordinarily does not. A prompt functions more like an instruction or idea; the AI system decides how that instruction is expressed, and the same prompt can produce very different results.
There is a nuance. If you provide your own expressive material as input, such as your own drawing or text, and that human-authored expression is perceptible in the output, your contribution can remain protected.
What can be protected in AI-assisted work
Using AI does not disqualify a work from copyright. Protection is available for the human contributions, which may include:
- Human-written content: original text you write yourself, even if it appears alongside AI-generated material.
- Creative modifications: substantial, creative changes you make to AI output. Minor or mechanical edits generally are not enough.
- Selection, coordination, and arrangement: the creative way you select and arrange elements, such as AI images combined with your own text in a book or campaign, can be protected as a compilation, even if individual AI elements are not.
In one well-known Copyright Office decision, a comic book's human-written text and the author's selection and arrangement of images were protected, while the individual images generated by an AI tool were not.
Registering AI-assisted work with the Copyright Office
Registration is generally required before suing for infringement of a U.S. work, and timely registration makes additional remedies available. For AI-assisted work, applicants should:
- Disclose AI-generated material that is more than minimal.
- Exclude that material from the claim and describe the human author's contribution.
- Correct earlier applications that did not disclose AI-generated content.
Failing to disclose AI-generated material can put a registration at risk.
Contract rights are not copyright
AI platforms' terms of service often say users own or may use their outputs. Those terms govern your relationship with the platform, but they cannot create copyright where the law does not recognize it. You may have the right to use an output without having any ability to stop others from copying it.
What this means for your business
- Keep meaningful human creative control over important work, and document it with drafts, revisions, and notes.
- Identify which assets are most valuable and evaluate copyright registration for their human-authored elements.
- Use trademark protection for brand names and logos, which does not depend on copyright. See How to Protect AI-Generated Logos, Images, and Marketing Content.
- Make sure employees and contractors assign their rights to your business in writing.
