“The Court has no choice but to grant summary judgment to Meta on the plaintiffs’ claim that the company violated copyright law by training its models with their books,” wrote US District Court judge Vince Chhabria. Kadrey v. Meta was one of the first cases of its kind; now there are dozens of similar AI copyright lawsuits winding through US courts. This is the second major ruling in the AI copyright world this week; on Monday, US District Court judge William Alsup ruled that Anthropic’s use of copyrighted materials to train its own AI tools was legal. They also assess whether the new work causes “market harm,” or hurts the original rights holder financially. Other legal experts highlighted Chhabria’s focus on market harm, too, noting that it could shape how future AI copyright cases are argued.
