Discovery ongoing.

Possible Outcomes

Plaintiff (Thomson Reuters) wins
If Thomson Reuters prevails, the court's ruling on the fair use of Westlaw headnotes would establish that AI companies cannot use copyrighted materials for training without explicit permission. This could lead to significant operational changes for Ross Intelligence, with potential damages reaching millions based on lost profits and market harm [12, 19]. The ruling would also deter other AI firms from similar practices, emphasizing the need for licensing agreements and compliance with copyright laws [14, 18]. The question of whether Ross's use was transformative remains critical, as the broader implications for AI training practices and creator compensation are still unresolved. Additionally, the ruling may increase scrutiny on data governance and privacy obligations, leading to heightened discovery burdens in future litigation [16, 19]. The debate over adequate compensation for creators, especially regarding AI-generated content, continues to be a contentious issue in copyright law [14, 19].
Defendant (Ross Intelligence) wins
If Ross Intelligence wins, it could mark a significant victory for AI companies, potentially broadening the interpretation of fair use to include transformative uses in AI training. This could shift how courts assess the use of copyrighted materials, especially where the distinction between transformative and derivative use is unclear [16, 18]. However, the ruling may not fully address the economic challenges faced by content creators, who could see their works devalued and their bargaining power weakened due to AI advancements [14, 19]. The debate over whether AI-generated outputs are transformative remains contentious, as some argue they can replicate original works, complicating fair use claims [19, 20]. Furthermore, the ruling may not clarify data governance and privacy obligations, leaving unresolved issues regarding data sourcing and compliance with copyright laws [16, 18].
