Fusion42 · 1 October 2026 · Fusion42 review

A US appeals court has rejected the 'fair use' defence for AI training data, upholding Thomson Reuters' copyright claims in a case supported by RIAA and NMPA.

This Wire brief sits within Fusion42's coverage of AI & ML, and 7 sources have reported it between 29 Sep 2026 and 2 Oct 2026.

◆ ◆ The Wire takeaway

US copyright law just tightened for AI training data, hitting vendors using unlicensed content. You face a clear legal risk today if your AI models ingest copyrighted materials without permission.
