I don’t think we need a court case for that. Model weights aren’t copyrightable by the trainer in the US. Copyright only protects works of human authorship, and training a network is not authorship. If the model weights encode other copyrighted works literally enough then they may be copyrighted by the author(s) of the works, that is a gray area. But the training process itself is not authorship and doesn’t confer copyright.
