Then, last month\u2019s unanimous <em>UpCodes<\/em> panel answered that question: Yes, fair use permits it.<\/p>\n<p>ROSS draws parallels between its situation and that of UpCodes. West, like the <em>UpCodes<\/em> plaintiff, is a recognized industry leader whose users purchase subscriptions to access copyrighted materials. ROSS, like the <em>UpCodes<\/em> defendant, is a for-profit startup that built a legal research platform using \u201ccopyrighted\u201d content (the word is in quotes in the brief) without securing a license, and both employed freemium business models offering AI-powered tools.<\/p>\n<p>ROSS goes factor by factor through the fair use analysis, arguing that <em>UpCodes<\/em> requires reversal on the first and fourth factors, where the district court ruled against it, and affirmance on the second and third, where the district court found for ROSS.<\/p>\n<p>On the critical first factor \u2014 the purpose and character of the use \u2014 ROSS argues the district court made two errors that <em>UpCodes<\/em> now exposes. First, the district court analyzed ROSS\u2019s subjective purpose (it found ROSS \u201ctook the headnotes to make it easier to develop a competing legal research tool\u201d), whereas <em>UpCodes<\/em> clarifies that the first factor calls for an objective inquiry.<\/p>\n<p>Second, the district court conflated ROSS\u2019s purpose with the expressive similarity of the output, which <em>UpCodes<\/em> says is the wrong inquiry. ROSS\u2019s objective use \u2014 training an AI model on the relationships among legal words, so that the headnotes would not appear in the final product at all \u2014 is, ROSS contends, at least as transformative as what UpCodes did, and arguably more so, because it \u201cinvolved a change in medium.\u201d<\/p>\n<p>On the fourth factor \u2014 market harm \u2014 ROSS argues the district court made a categorical error by treating \u201clegal research platforms\u201d as the relevant market, rather than examining what West actually derives from the specific works at issue, its headnotes.\u00a0Under <em>UpCodes<\/em>, ROSS says, the court should have looked at the market for headnotes specifically and the percentage of Westlaw revenues attributable to them.<\/p>\n<p>ROSS also argues that West conceded it has no evidence of actual market harm \u2014 no documented lost subscribers, no lost revenue traceable to ROSS \u2014 and that <em>UpCodes<\/em> requires courts to examine the record closely rather than inferring harm from the mere fact of competition.<\/p>\n<p>\u201cIn 2020, West should have responded to ROSS with innovation,\u201d the brief concludes. \u201cInstead, West chose litigation. Copyright rewards the former, not the latter.\u201d<\/p>\n<h3><strong>Thomson Reuters: <em>UpCodes<\/em> Changes Nothing<\/strong><\/h3>\n<p>In <a href=\"https:\/\/www.lawnext.com\/wp-content\/uploads\/2026\/05\/3d-Cir.-25-02153-dckt-000195_000-filed-2026-05-11.pdf\" rel=\"nofollow noopener\" target=\"_blank\">its supplemental brief<\/a>, Thomson Reuters, represented by Kirkland &amp; Ellis, takes the opposite view: <em>UpCodes<\/em> does not move the needle here at all, and in fact demonstrates why ROSS\u2019s conduct falls on the wrong side of the fair use line.<\/p>\n<p>TR\u2019s brief argues that the fundamental distinction in fair use doctrine is between commercial, substitutive uses (which are not protected) and uses serving a genuinely different purpose that do not supplant the original work\u2019s markets. <em>UpCodes<\/em>, TR contends, is simply an application of that settled framework \u2014 and the factual differences between that case and this one point squarely against ROSS.<\/p>\n<p>The key distinction, TR contends, is that UpCodes copied standards that had been legally incorporated into law and made them freely available, serving a genuine access-to-law purpose it could not achieve without copying those specific works. But ROSS had no such access-to-law purpose. The case law was already free. ROSS had it.<\/p>\n<p>Further, unlike UpCodes \u2014 which copied only the law-incorporated versions of standards and made them available at no charge \u2014 ROSS was fully commercial, explicitly marketing its product as a direct Westlaw replacement and, according to TR, even bragging to prospects that it would \u201cbring an end to Westlaw contracts.\u201d<\/p>\n<p>TR also invokes a California district court\u2019s recent ruling in <a href=\"https:\/\/authorsguild.org\/app\/uploads\/2025\/06\/gov.uscourts.cand_.434709.231.0_3.pdf\" rel=\"nofollow noopener\" target=\"_blank\"><em>Bartz v. Anthropic PBC<\/em><\/a>, which it quotes for the proposition that using a proprietary system for finding court opinions to create a competing AI tool for finding court opinions \u201cwas not transformative.\u201d<\/p>\n<p>On the second factor, TR argues that <em>UpCodes<\/em> actually underscores the distinction. The UpCodes works had \u201clegal force\u201d because they were incorporated into statutes. Westlaw headnotes are not law. They reflect TR\u2019s attorney editors\u2019 legal analysis and organization \u2014 proprietary editorial work that the Supreme Court recognized as copyrightable in <em>Callaghan v. Myers<\/em> back in 1888.<\/p>\n<p>On the fourth factor, TR argues the evidentiary record here is far richer than in <em>UpCodes<\/em>, where market harm evidence was thin and many of the incorporated standards at issue were outdated.<\/p>\n<p>By contrast, the record here, TR says, shows customers who switched from Westlaw to ROSS, ROSS\u2019s CEO acknowledging that switch, and evidence of harm not just to the original Westlaw subscription market but to the emerging market for AI training data \u2014 a harm the <em>UpCodes<\/em> panel never had to address.<\/p>\n<h3><strong>The Bottom Line<\/strong><\/h3>\n<p>To some extent, the parties\u2019 differing interpretations of the <em>Upcodes<\/em> ruling reflects the ambiguity in the ruling itself. The 3rd Circuit grounded its fair use analysis heavily in UpCodes\u2019 specific purpose of disseminating the law, a purpose it found compelling and independent.<\/p>\n<p>Whether that reasoning extends to AI training on editorial legal content, or whether it is restricted to incorporated-standards cases, is exactly the question the 3rd Circuit now has to answer in this appeal.<\/p>\n<p>ROSS\u2019s argument \u2014 that teaching a machine the language of the law is analogous to UpCodes\u2019 dissemination of legal standards \u2014 is creative and timely, given how AI has developed during the pendency of this case.<\/p>\n<p>TR\u2019s counter \u2014 that ROSS\u2019s purpose was simply to replicate what Westlaw does \u2014 has the advantage of following the district court\u2019s reasoning and finding factual support in the record.<\/p>\n<p>For now, the ball is back in the hands of the court.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>The long-running copyright litigation between legal research giant Thomson Reuters and now-shuttered legal research startup ROSS Intelligence took another interesting turn this week, following the 3rd U.S. Circuit Court of Appeals\u2019 order that the parties file supplemental briefs addressing the impact of its recent ruling in American Society for Testing &amp; Materials v.
