The Third Circuit has delivered one of the most important appellate rulings yet at the intersection of copyright law, legal publishing, and artificial intelligence. In affirming Thomson Reuters’ win against Ross Intelligence, the court left in place a ruling that Ross infringed Westlaw headnotes and could not shield its conduct under fair use.

For legal professionals, the decision is significant well beyond this long-running dispute.

The Tenth Circuit’s August 20, 2026 opinion in No. 25-1096 is a reminder that even relatively compact appellate decisions can carry meaningful procedural and strategic implications for litigants. While the significance of the ruling will depend on the underlying claims and posture of the appeal, the decision is most useful for practitioners as a guide to how the court is approaching review of district court rulings, preservation of issues, and the framing of appellate arguments.

At a high level, the court resolved the appeal by applying familiar standards of review and focusing closely on the record developed below.

One of the less glamorous but increasingly important legal developments is not a ruling, verdict, or settlement at all: it is the difficulty of verifying what actually counts as “today’s” top legal news in a fragmented, access-restricted media environment.
