In a recent legal confrontation, Thomson Reuters has presented its arguments to the 3rd U.S. Circuit Court of Appeals, insisting that ROSS Intelligence’s replication of Westlaw’s headnotes for AI training was an act of theft, not an innovation. This follows the Delaware district court’s decision which found that ROSS had indeed infringed on Westlaw’s copyrights by copying thousands of attorney-written headnotes to develop an AI-driven legal research tool.
The detailed redacted brief submitted by Thomson Reuters emphasizes that the notion of using copy-protected material to create competing products is equivalent to theft, regardless of the context, including AI applications. The document, prepared by Kirkland & Ellis partners Dale Cendali, Joshua Simmons, and Miranda Means, staunchly supports the idea that Westlaw’s headnotes are creative editorial efforts, reflecting deep legal analysis rather than mere factual reporting.
Thomson Reuters argues that creative editorial decisions, such as crafting the phrasing of legal points, creating headnotes, selecting relevant case facts, and linking these within the West Key Number System, demonstrate the headnotes’ copyrightable nature under legal precedents like Callaghan v. Myers (1888) and Georgia v. Public.Resource.Org (2020).
The legal giant accuses ROSS of deliberately trying to replicate Westlaw’s offerings after being denied a license. ROSS’s actions included hiring LegalEase Solutions to covertly collect data from Westlaw to train its AI model, resulting in unauthorized copies of thousands of annotated legal cases and editorial summaries.
The crux of Thomson Reuters’ argument is that the actions by ROSS constituted a direct substitution in the legal research platform market, eliminating transformative use. This stance connects with the Supreme Court’s 2023 decision in the Andy Warhol Found. for the Visual Arts v. Goldsmith case. They argue that ROSS’s use was non-transformative as it essentially replicated Westlaw’s purpose of aiding legal research, unlike cases such as Google Books which provided added value without substituting the original works.
Additionally, the brief focuses on how ROSS’s actions could detrimentally impact Westlaw’s various markets—both existing and potential ones—by allowing competitors to utilize copied materials for developing parallel AI-powered legal tools.
While conceding that AI advancement could plausibly involve invoking copyrighted materials, Thomson Reuters insists that ROSS’s conduct does not fit such paradigm but rather reflects parasitic copying. They assure that AI progress is feasible without compromising protected materials, referencing their own legacy of integrating AI within their services since the 1990s, such as the development of the WestSearch Plus AI research feature.
As the legal proceedings continue, the outcome of this appeal could have significant repercussions for the balance between copyright protection and AI advancement in legal research. To delve deeper into this ongoing legal battle, follow further updates from here.
