The US Supreme Court has settled the AI copyright debate—AI alone CANNOT own copyright. In Thaler v. Perlmutter, the Court denied certiorari on March 2, 2026, affirming that "human authorship is bedrock requirement." Dr. Stephen Thaler's DABUS AI has been denied copyright since 2018. Creators using AI can still claim copyright—but only on human-authored elements.

What Happened: March 2, 2026
On March 2, 2026, the US Supreme Court declined to hear an appeal in Thaler v. Perlmutter, letting stand a 2025 DC Circuit ruling that AI-created works cannot receive copyright protection. This marks the final word on whether AI systems like DABUS can own intellectual property—the answer is a definitive no.
The case began in 2018 when Dr. Stephen Thaler attempted to copyright artwork created by his AI system "DABUS" (Device for the Autonomous Bootstrapping of Unified Sentience). The US Copyright Office rejected the application, stating that copyright requires human authorship. Thaler challenged this decision through the courts, reaching the DC Circuit in 2025 and now the Supreme Court in 2026.

What the Supreme Court Actually Ruled
The Supreme Court's decision to deny certiorari means it declined to review the case, effectively letting the DC Circuit's 2025 ruling stand. The key legal principle from that ruling: "human authorship is the bedrock requirement" for copyright protection.
This doesn't mean AI-generated content has no legal protection—it means AI cannot be treated as the "author" under copyright law. The work itself enters the public domain immediately upon creation, meaning anyone can use it without permission or payment.
Can You Copyright AI-Assisted Work?
Yes, but only the human parts. The Copyright Office has clarified that when humans use AI tools as part of the creative process, copyright protection may apply to the human-contributed elements. This is crucial for:
- Prompts: Carefully crafted AI prompts may be copyrightable as literary works
- Edits: Human editing, arrangement, and curation of AI output
- Integration: Combining AI-generated elements with original human creative work
- Selection: Choosing which AI outputs to use and how to present them
What This Means for Different Groups
For Creators and Artists
If you use AI tools like Midjourney, DALL-E, or Stable Diffusion, you cannot claim copyright on the AI-generated image alone. However, if you significantly edit the output, add original elements, or incorporate it into a larger human-created work, those human contributions may be protected.
For Businesses and Agencies
Companies using AI for marketing content, product designs, or creative work should note that AI-generated elements may be freely used by competitors. Protect your investment by documenting human creative input and focusing on elements that require substantial human authorship.
For Developers and AI Companies
AI companies cannot claim copyright on outputs from their models. This affects business models around AI-generated content and may influence how companies position their offerings—emphasizing the tool rather than the output.

Practical Steps to Protect Your Work
Document Your Human Contributions
Keep records of your creative decisions, edits, and additions to AI-generated content. This establishes the human authorship needed for copyright.
Add Substantial Human Elements
Don't rely solely on AI output. Add original illustrations, written content, photography, or significant creative transformations.
Use Contracts and Licenses
When working with clients, specify what AI tools were used and what human elements you own. This prevents disputes over ownership.
Consider Trade Secret Protection
For business-critical AI workflows, consider protecting your methods as trade secrets rather than relying on copyright.
