Amazon asked the Ninth Circuit to rehear its case against Perplexity before 11 judges, arguing that last month’s ruling stripped site owners of the ability to set terms for the AI agents entering their systems. A three-judge panel had held that Perplexity’s users, rather than Perplexity, are the ones reaching Amazon when the Comet assistant shops, which made the Computer Fraud and Abuse Act claim unlikely to succeed and lifted the ban on the agent. Amazon’s petition argues the record cuts the other way, because a shopper who types a generic request like “order paper towels” never chose to visit Amazon at all, while Perplexity’s reasoning layer sends the assistant into the store, presents the shopper’s saved credentials, and clicks through secured pages.
