Short answer: The U.S. Supreme Court has not ruled that AI-generated art can never be copyrighted. On March 2, 2026, it denied Stephen Thaler’s petition in Thaler v. Perlmutter (No. 25-449), leaving a D.C. Circuit decision about one work that Thaler described as produced autonomously by his AI system. A denial of certiorari is not a Supreme Court merits opinion.

For creators, the practical rule is narrower: U.S. copyright may protect original human expression in a work made with AI, but material generated without sufficient human control is not protected under the Copyright Office’s current framework. The analysis is fact-specific, and prompts alone generally are not enough.

What the Supreme Court actually did
The Supreme Court docket records a single action in this dispute: “Petition DENIED” on March 2, 2026. The Court did not issue an opinion deciding whether AI-generated art is copyrightable, did not affirm the D.C. Circuit’s reasoning, and did not create a nationwide Supreme Court merits rule on every use of generative AI.
#1 Best Overall
The judgment that remains in force is the D.C. Circuit’s March 18, 2025 decision. That appellate ruling concerns the particular application and factual record before it, not every image, painting, video, or other work made with an AI tool.
What happened in Thaler’s case
The work and the registration application
Stephen Thaler sought registration for A Recent Entrance to Paradise. His application identified his Creativity Machine as the creator and represented that the image was generated autonomously, without human authorship.
The Copyright Office refused registration. The D.C. Circuit upheld that refusal, reasoning that the Copyright Act’s reference to an “author” requires a human author for the work at issue. The court also rejected Thaler’s work-made-for-hire theory because, on those facts, no copyrightable interest first existed in the machine-generated work that could be transferred.

What the appellate decision did not decide
The D.C. Circuit did not resolve every question involving people who use AI as part of a creative process. It addressed a work presented as wholly machine-generated. It also did not decide whether the Constitution independently requires human authorship; its ruling rested on the Copyright Act and relevant precedent.
Thaler’s petition argued that the 1976 Copyright Act should permit nonhuman authorship. That was the petitioner’s position, not a holding adopted by the Supreme Court or the D.C. Circuit.
How U.S. copyright law treats AI-assisted art
The U.S. Copyright Office’s Part 2 report, published January 29, 2025, says existing copyright law can address AI-generated outputs without a new statute. Its framework separates the human-authored parts of a work from material for which the AI system determines the expressive details.
| Situation | Human role | Treatment described by the cited authorities |
|---|---|---|
| Autonomous output with no claimed human creative contribution | The AI system determines the expressive elements | Thaler’s registration was refused; the D.C. Circuit held that the Copyright Act requires human authorship for that work. |
| AI-assisted or AI-containing work with human expression | The person contributes original expression, creative selection or arrangement, or creative modifications | The qualifying human-authored elements may be protected; the determination is case by case. |
| Prompt-only generation | The person supplies instructions while the tool determines the expressive details | The Copyright Office says prompts alone do not provide sufficient control based on current generally available technology. |
These categories are analytical examples, not an automatic registration test. The Office does not supply a guaranteed number of edits, prompt iterations, hours of work, or percentage of human content that establishes authorship.
What human contributions can be protected
Original expression that appears in the finished work
If you create perceptible expressive material yourself—such as hand-painted elements, original text, or other protectable components—copyright may cover that human-authored expression even when AI-generated material is also present.
Rank #3
Creative selection, coordination, or arrangement
A person’s creative choices about which generated elements to use and how to organize them can be protectable when those choices produce an original selection, coordination, or arrangement. Protection extends to the human-authored structure, not automatically to every generated element placed within it.
Creative modifications
Substantive, creative changes made by a human may qualify as authorship. A routine or purely mechanical adjustment does not receive an automatic safe harbor, and the Office’s analysis turns on the expressive contribution in the particular work.
Why a detailed prompt is not a guaranteed copyright claim
The Copyright Office states: “Based on the functioning of current generally available technology, prompts do not alone provide sufficient control.” A prompt can communicate an idea, direction, or desired result while the system still selects the concrete visual details. Prompt length, specificity, or the number of attempts therefore does not by itself establish authorship.
The relevant question is what expressive elements you actually controlled and contributed to the finished work. Keep records of your process, but do not assume that a prompt log alone proves copyright in the resulting image.
Rank #4
How registration works when a work includes AI material
Disclose more-than-de-minimis AI-generated content
The Copyright Office’s March 2023 registration guidance instructs applicants to disclose AI-generated material that is more than de minimis and to briefly describe the human author’s contribution. Identify the elements you believe are human-authored rather than claiming the entire output without qualification.
Describe the human contribution clearly
Explain the original expression, selection or arrangement, and creative modifications you made. Use the Office’s current application instructions when filing, because registration procedures and forms can change.
Understand partial protection
The Office’s January 2025 report discusses Zarya of the Dawn. Registration covered the human-authored text and the human’s creative selection, coordination, and arrangement, while the Midjourney-generated images were not treated as human-authored. A composite work can therefore receive protection for its qualifying human elements without granting copyright in every component.
The Office also reports registering hundreds of works incorporating AI-generated material, with coverage of human contributions. “Hundreds” is the reported scale; the cited summary does not provide an exact count.
Best Value
A practical decision path for creators
- Identify what the system generated. Separate generated images, text, or other material from elements you made yourself.
- Describe your expressive choices. Note original elements you created, the selection or arrangement you designed, and creative changes made after generation.
- Assess control, not effort alone. Time spent, prompt length, and many iterations do not automatically establish authorship.
- Prepare an accurate registration claim. Disclose more-than-de-minimis AI-generated material and identify the human-authored portions under the Office’s current instructions.
- Limit the claim to what you can support. Do not represent autonomous material as human-authored simply because you commissioned or paid for its creation.
What this decision does—and does not—say about AI art
The decision says that the autonomous work presented in Thaler’s application could not be registered on the record before the D.C. Circuit. It does not make all AI-assisted art uncopyrightable, and it does not promise copyright for every work that receives manual editing.
This discussion is limited to U.S. copyrightability and registration. Whether using copyrighted works to train an AI system infringes copyright is a separate issue in the Copyright Office’s AI initiative and is not resolved by Thaler.
Bottom line for an AI image creator
If an AI system independently determines the expressive content and you claim no human authorship, the Thaler ruling is a serious obstacle to registration in the United States. If you contribute protectable expression, creative selection or arrangement, or creative modifications, those human-authored elements may be eligible for protection. The Supreme Court’s certiorari denial left the lower-court judgment in place; it did not decide the broader question “Can I copyright AI-generated art?” for every creator.
