By Blake BrittainAug 4 (Reuters) - A U.S. appeals court on Tuesday overturned a ruling that had temporarily barred Perplexity from using its AI-powered agentic shopping tools on ‌Amazon's platform. Circuit Court ‌of Appeals determined that Amazon was unlikely to succeed on its claim that Perplexity's AI agents violated a federal ​computer-hacking law. Perplexity responded that the lawsuit lacked merit and was a "bald attempt" to block Amazon ‌users from using Comet because AI agents "don't have eyeballs ​to see the pervasive advertising Amazon bombards its users ​with." A federal judge in California temporarily blocked Perplexity in ​March from using its agentic AI on Amazon's platform, finding Amazon had ‌presented "strong evidence" that Perplexity's AI agent broke ​a U.S. computer fraud ​and abuse law. The ‌appeals court said it was Perplexity's users, using the company's AI agents, who "accessed" ​Amazon's platform under the law, rather than Perplexity itself.
