Thomson Reuters Wins First Major AI Copyright Case In the US 54

An anonymous reader quotes a report from Wired: Thomson Reuters has won the first major AI copyright case in the United States. In 2020, the media and technology conglomerate filed an unprecedentedAI copyright lawsuit against the legal AI startup Ross Intelligence. In the complaint, Thomson Reuters claimed the AI firm reproduced materials from its legal research firm Westlaw. Today, a judge ruled (PDF) in Thomson Reuters' favor, finding that the company's copyright was indeed infringed by Ross Intelligence's actions. "None of Ross's possible defenses holds water. I reject them all," wrote US District Court of Delaware judge Stephanos Bibas, in a summary judgement. [...] Notably, Judge Bibas ruled in Thomson Reuters' favor on the question of fair use.

The fair use doctrine is a key component of how AI companies are seeking to defend themselves against claims that they used copyrighted materials illegally. The idea underpinning fair use is that sometimes it's legally permissible to use copyrighted works without permission -- for example, to create parody works, or in noncommercial research or news production. When determining whether fair use applies, courts use a four-factor test, looking at the reason behind the work, the nature of the work (whether it's poetry, nonfiction, private letters, et cetera), the amount of copyrighted work used, and how the use impacts the market value of the original. Thomson Reuters prevailed on two of the four factors, but Bibas described the fourth as the most important, and ruled that Ross "meant to compete with Westlaw by developing a market substitute."
"If this decision is followed elsewhere, it's really bad for the generative AI companies," says James Grimmelmann, Cornell University professor of digital and internet law.

Chris Mammen, a partner at Womble Bond Dickinson who focuses on intellectual property law, adds: "It puts a finger on the scale towards holding that fair use doesn't apply."

    If the lawsuits block US AI companies, what is to prevent Chinese AI companies from completely ignoring them?

    I can see the US AI companies facing serious challenges in the not-so-distant future. The Chinese already have a labor and cost advantage. I am reminded of what the Japanese did to the US electronics industry.

      International copyright law. The thing that Chinese companies rely heavily on to protect their intellectual property.

      The Japanese didn't steal anything from the US electronics industry. They started out making basic components, developed their own ICs, and licenced US designs. Famously NEC licenced Intel's 8086, and then improved it and got sued. They won in US court - their licence was deemed to give them the right to produce 286 and 386 compatible parts as well. They also did the R&D to get ahead, e.g

    This involved human beings taking summaries from a database, rewriting them negligibly, and then loading that modified content into generative AI, and doing so in explicit violation of rules saying not to use the database for that purpose, with the explicit intent to build a service that competes against the service provided by the original database. This isn't a particularly broad decision.

    This is basically the phone book copying case, but without the factuality defense. Had they started with the original case notes instead of the other company's summaries, they probably would have been in the clear, but they did not.

    • by thczv ( 541683 )
      I think the mistake this judge made is inferring copying because the summaries are similar. Access plus similarity equals copying. But similarity is inevitable whenever multiple parties are summarizing the same content. The shorter the summary, the more similar it will be to other summaries (as long as they are all accurate). I don't think this is the kind of thing the Copyright Act was trying to protect against. If you call this infringement, you basically give preference to the first summarizer, which ten

        No, the parent poster has this correct. The creators of the infringing content were explicitly instructed to use the infringed content to develop the infringing content, not the actual court opinions that are public domain. This fact (which has been read in the light most favorable to the infringer) is alone enough to render your observations moot. By which I do not mean "worthy of debate" but rather "having little to no relevance or significance."

    The article didn't even say what the alleged copyright violation was. The fair use doctrine doesn't matter until we know what the use actually is.

    Artificial neural networks are trained by "reading" text, just like our brains are trained by reading text. If the claim is that training an AI by reading text is not "fair use" because training the AI is an intention to create a competitor, then that text cannot be read by humans either. Now, it could be argued that humans do not intend to "create a competitor" by reading text, but law students certainly do. Can law students, or attorneys, NOT read legal documents because it is not "fair use"? The usage here is very important, if the argument is simply that training is not fair use then there is going to be a big problem.

      I looked at the actual decision, it seems really crappy to me. It doesn't appear to me to say what the "use" actually was. It would seem that the actual "copyright violation" was made by a third party prior to involvement by any AI at all. No consideration of the AI itself is even made. Instead, the judge only seems to care that copyrighted materials were fed into a system intended to be a commercial product. Sure, but attorneys practicing law do that too. My comment remains, can law students read cop

          Software is not a person and the weights that result from training this software are nothing but a lossy encoding of the training data.

          The judge is right to only care that they fed copyrighted material into the software and disregard any attempt at drawing parallels to attorneys practicing law.

        My comment remains, can law students read copyrighted legal writing pursuant to their law degrees? This judge says no.

        The law recognizes people as a special case, even if you do not. LLMs are machines, not people. Your "argument" is essentially a hallucination and has no merit.

        It must be exhausting to have people expect you to read to the fourth paragraph when you "looked at the actual decision." It's right fucking there:

        "In other words, Ross built its competing product using Bulk Memos, which in turn were built from Westlaw headnotes."

        It can't be a competing product unless the human lawyers can get summaries out of it. Which the judge then found, when comparing to the original summaries to which access was established, substantial similarity sufficient to decide infringement

      So read a lot of copyright works, memorize it exactly, then you regurgitate it almost exactly and try to sell that. This is not fair use, even for a human. At the very least, summarize without copying. And yes, in legal arenas this means summarize the summaries if the summaries are copyrighted.

      • Sounds like what law school trains lawyers to do.
        • Yeah but laws happen to be public documents that are meant to be copied and learned, so no copyright violation there.
          Also it becomes a life profession to have humans dedicate that level of effort to achieve such memorization.

          • Interpretations of the law, written down into books, are copyrighted though. As opposed to actual legal rulings. That's the snag in this particular story.

    • I would suggest that once you process with automation there is a difference.

      Adding the automation fundamentally changes the scale of how far and wide and fast an idea can go.

      I think its pretty obvious that harvesting information on an industrial scale with intent to monetize is quite obviously not fair use.

        I agree UNLESS you are making it copyleft or bsd type open and widely distributing. It really doesn't matter if you attempt to monetize if you've rendered the advantage into the commons.

      • The problem there is that, for several years now, there has been a narrative which has even made inroads into Slashdot that "but thEy Did IT On A COmpUteR" means nothing and that the law should be applied as though the computer does not fundamentally change the action and should be treated as if it were a person under the law. There have been legal cases already that were adjudicated with that very conclusion. You seem to want to go with the alternative conclusion that using a computer to do something DOE

      We don't have to treat artificial computing systems deliberately designed to encode and store training data as weights in the same way as real brains and therefore parallels between their operation don't matter. Copyright is artificial, brains are not and predate copyright... a double standard on that basis is just fine.

    It has never been intended for companies, business of any kind, or any individual redistributing to another party.

    Perhaps libraries and such also have fair use protections, but that is about it.
    • Fair use very often about something bigger than the individual. Fair use does cover parodies, even if those parodies are for other people and those parodies make money. Also being allowed to copy a couple of sentences into a news article or your term paper.
