Legal Analysis: Copyright Status of AI-Generated Works
Let me lay out the current legal framework as clearly as I can. This is one of the fastest-moving areas of IP law, but the foundational principles are becoming clearer.
1. The Human Authorship Requirement
U.S. copyright law protects "original works of authorship" (17 U.S.C. 102). The Copyright Office has consistently maintained that "authorship" requires a human author. This isn't new — it goes back to Burrow-Giles Lithographic Co. v. Sarony (1884), where the Supreme Court held that copyright could protect a photograph because a human made creative choices in composing, lighting, and arranging the subject.
2. Thaler v. Perlmutter (D.D.C. 2023)
This was the first federal court case directly addressing AI-generated works. Stephen Thaler applied for a copyright registration for an image generated entirely by his AI system, DABUS, naming the AI as the author. The court (Judge Howell) held that copyright requires human authorship and that a work generated entirely by AI without human creative input cannot be copyrighted. The ruling was straightforward: "Human authorship is a bedrock requirement of copyright."
3. Zarya of the Dawn (Copyright Office, 2023)
This is the more nuanced and practically important decision. Kristina Kashtanova registered a graphic novel that combined AI-generated images (from Midjourney) with human-authored text and human-arranged page layouts. The Copyright Office ruled:
- The individual AI-generated images were not copyrightable because Kashtanova's text prompts to Midjourney did not constitute sufficient creative control over the resulting images
- The text she wrote was copyrightable (standard human authorship)
- The selection and arrangement of images and text into a cohesive work was copyrightable as a compilation under 17 U.S.C. 103
This is the key framework: a work can contain both copyrightable and non-copyrightable elements. Your copyright protection extends only to the human-authored portions.
4. The "Sufficient Human Authorship" Standard
The Copyright Office's February 2023 guidance established that copyright registration requires "sufficient human authorship." The question is: where does the human's creative contribution end and the AI's begin? The Office has indicated that:
- Typing a prompt into an AI tool is generally not sufficient human authorship (similar to giving instructions to a commissioned artist — you don't own the copyright just because you described what you wanted)
- Selecting, arranging, and modifying AI outputs can constitute sufficient human authorship if the creative choices are meaningful
- Using AI as one tool among many in a creative process (e.g., generating a rough draft, then extensively editing and revising) is more likely to result in copyrightable work
The bottom line: the more human creative input you add on top of the AI output, the stronger your copyright claim. Pure prompt-to-output with no further human modification is the weakest position.
