Best part is, it's likely to have a different answer in every country, who knows what'll happen, not every country implicitly sides with the ones with the most money.

Well, eventually it'll probably be added to the Berne Convention agreement or some such.

That's my feeling on the endgame too, but it'll probably be a decade before we get anywhere near it.

I want this question to have an interesting answer, but everyone knows that if this question ever goes to the courts, ownership will go to the people in charge with the money. The idea that Anthropic may not own Claude Code just because Claude wrote it is wishful thinking.

I'm not sure Anthropic would appreciate the liability that ownership would imply.

You're right, I guess maybe I mean in any serious actionable way. Senior, non technical people leave plenty of money on the table by thinking they're protecting something valuable or they have some kind of secret sauce. It's all silly is what I meant to say, and digging into the technicalities of whether your code is truly copyrightable is kind of pointless. It's all vibes.

The place where it concretely matters is M&A due diligence. Acquirers are now routinely asking about AI tool usage in development and running license scans as a condition of closing. A codebase that cannot demonstrate human authorship over its core IP, or that contains GPL contamination, creates a representation and warranty problem in the purchase agreement. For most companies day to day you are right. For the compa…

Very interesting, I had no idea. That's probably going to be a very painful lesson learned by all the startups that have been pumping out AI code. I know of several just among my peer groups that will be shocked and dismayed by this. Thanks for sharing that!

Personally, I think that the human directing the agent owns the copyright for whatever is produced, but the ability for the agent to build it in the first place is based off of stolen IP. I'm concerned about the copyright 'washing' this enables though, especially in OSS, and I think the right thing for OSS devs to do is to try to publish resulting code with the strongest copyleft licensing that they are comfortable w…

Funny how the copyright industry was able to spin copyright infringment into the pejorative "stealing". If you still have the item, what was stolen?

Dowling v. United States, 473 U.S. 207 (1985): The Supreme Court ruled that the unauthorized sale of phonorecords of copyrighted musical compositions does not constitute "stolen, converted or taken by fraud" goods under the National Stolen Property Act

The work-for-hire doctrine actually supports your intuition more than the AI authorship question does. The reason Anthropic likely owns Claude Code has little to do with whether Claude wrote it and everything to do with the employment contracts of the engineers who directed it. The DMCA takedown question is genuinely interesting though because DMCA requires the claimant to assert copyright ownership in good faith. If…

I have trouble believing that the DMCA claims would be found to be in bad faith when they were made at a time when the question of what degree of human input is required to acquire copyright on AI generate code hasn't been resolved at all. It doesn't seem like bad faith to think that copyright is stronger than the courts end up thinking, just being mistaken.

fair correction, updated the piece to reflect this. Bad faith under DMCA requires knowing the claim is false, not merely being wrong. A good faith belief in copyright ownership, even one that turns out to be mistaken, is a defense. The more accurate framing is that if the codebase is found to be predominantly AI-authored, the takedowns would fail on the threshold question of whether there is a valid copyright to assert, which is a different issue from intent.

"if Claude was trained on the LGPL-licensed codebase and its output reflects patterns learned from that code, can the output be treated as license-free? The emerging legal consensus is probably not, and assuming it can creates significant liability for anyone shipping that code commercially." Is there any citation for this "legal consensus"? I was not aware there was any evidence backed stances on this topic as of ye…

The chardet dispute is the closest thing to an active test case on this specific question, and you are right that it has not resolved into settled law. "Emerging legal consensus" was imprecise. The more accurate framing is: the legal community's working assumption, based on how copyright doctrine treats derivative works, is that training-data provenance travels with the output. That assumption has not been tested definitively in court yet.

Work-for-hire doctrine doesnt automagically absolve you from IP law. Microsoft and Intel already learned this in the nineties when they paid San Francisco Canyon Company to steal Apple code. https://en.wikipedia.org/wiki/San_Francisco_Canyon_Company LLMs are just code stealers, will gladly generate Carmacks inverse for you with original comments.

The San Francisco Canyon case is a good example of exactly the right distinction. Work-for-hire determines who owns the output, but if the process of creating that output involved copying protected material, the infringement claim runs separately. The piece makes this point on the open source contamination section: owning the output and having a clean chain of title to the output are different questions. You can own AI-generated code and still have a copyleft problem in it.

IMO this is the greatest argument against AI as technofascism. The general public seems to believe that AI will usher in technofascism by claiming corporate ownership of AI output: the independent entrepreneur will be unable to compete against the corporations compute, every piece of data about you will be stolen and monetized by AI, and you will own nothing. But AI might in fact do the exact opposite and reverse the…

The original bargain you describe, limited term in exchange for public disclosure, is exactly what makes the current situation strange. If AI-generated output falls into the public domain immediately, that is actually closer to the original intent of copyright than 95-year terms. The legal question is whether that outcome happens by design or by accident, and what it means for the people building products on top of AI-generated codebases right now.

This is of course assuming you take AI-generated code unchanged. But you don't, in my experience. And that generates a new work fully copyrightable even if the original wasn't. Just like how the fad a decade or so ago of taking Tolstoy and Jane Austen works and adding new elements -- "Android Karenina" and "Sense and Sensibility and Sea Monsters" are copyrighted works even if the majority of the text in them was from…

I'm sure it's not quite that simple. Only parts the parts of those knock-off works that aren't public domain could be copyrightable. If you only own the copyright to ten lines in a 10k line codebase, then it's probably fair use for someone else to just to take the whole thing. Plus what if Anna Karenina was GPL?

Anna Karenina is public domain, assuming you’re talking about the original? If you translate it then maybe you could release it under GPL, but bit odd?
