By losing I also mean reaching a settlement which is deemed by the mainstream media a win for the plaintiffs. The ruling must be legally binding.

As an example:

"George R.R. Martin, Jodi Picoult, John Grisham and Jonathan Franzen are among the 17 prominent authors who joined the suit led by the Authors Guild, a professional organization that protects writers’ rights. Filed in the Southern District of New York, the suit alleges that OpenAI’s models directly harm writers’ abilities to make a living wage, as the technology generates texts that writers could be paid to pen, as well as uses copyrighted material to create copycat work."
