Anthropic DMCA Takedown Challenges AI-Generated Code Copyright
Is this a scandal?
No longer — the story has resolved. Noise 1/100, cooling down, across 0 sources.
A legal challenge or counter-notice is likely to be filed by an affected developer, forcing a court to rule on the copyrightability of AI-generated code. This will probably lead to the U.S. Copyright Office issuing more specific guidance on 'hybrid' human-AI software development.
Noise 1/100 — louder than 89% of tracked AI controversies.
Why it matters
The incident tests trust in AI vendor security claims while raising unresolved questions about copyrightability of fully AI-generated software.
Key points
- Anthropic attributed the Claude Code source leak to a human-caused release packaging error, explicitly denying a security breach.
- Software engineer Casey Muratori challenged the copyright status of the leaked code based on Anthropic's claim of zero hand-written development.
- Mercor confirmed a separate supply chain attack, which Anthropic distinguished from its own internal packaging failure.
- The White House accused Chinese company Moonshot AI of distilling Anthropic models, creating parallel IP concerns.
- Current U.S. copyright guidance suggests purely AI-generated code may lack protection, complicating Anthropic's IP position.
The story
Anthropic confirmed it accidentally leaked part of its Claude Code source code, attributing the exposure to a release packaging issue caused by human error rather than a security breach. The company stated the incident was unrelated to a separate supply chain attack that affected hiring platform Mercor. Software engineer Casey Muratori subsequently questioned whether the leaked code is copyrightable under U.S. law, citing Anthropic’s own admission that developers do not write code by hand. Concurrently, the White House accused Chinese firm Moonshot AI of distilling Anthropic models, adding geopolitical tension to the disclosure. IBM also reported Q2 revenue of $17.2 billion amid broader industry scrutiny. Anthropic maintains the leak was an operational mistake and denies any external compromise of its systems. Legal experts note that U.S. Copyright Office guidance currently excludes purely AI-generated works from protection.
Who's involved
Argues that if developers do not write code by hand, the resulting output is not copyrightable and DMCA claims are invalid.
Asserts that its proprietary code, even if generated by AI, is protected intellectual property subject to DMCA enforcement.
Currently maintains that material produced by a machine without human creative input is not copyrightable.

The timeline
Legal Validity Questioned
Developer Casey Muratori publicly challenges the legal basis of the takedowns, citing lack of human authorship.
DMCA Notices Issued
Anthropic begins sending takedown notices to various hosting platforms regarding leaked or mirrored code.
The forecast
A legal challenge or counter-notice is likely to be filed by an affected developer, forcing a court to rule on the copyrightability of AI-generated code. This will probably lead to the U.S. Copyright Office issuing more specific guidance on 'hybrid' human-AI software development.
