March 17 (Reuters) - A U.S. appeals court has put a California judge's ruling on hold that had blocked Perplexity AI from using its artificial-intelligence-powered "agentic" shopping tool on Amazon's platform.

The 9th U.S. Circuit Court of Appeals halted the order on Monday while it considers Perplexity's request for a longer-term pause that would last through its appeal of the district court's decision.

Spokespeople for the companies did not immediately respond to requests for comment on the ruling on Tuesday.

Amazon sued Perplexity in November, accusing the AI startup of covertly accessing private Amazon customer accounts through its Comet browser and associated AI agent, and of disguising automated activity as human browsing. The lawsuit said ‌Perplexity's ⁠system posed security risks for customer data and that it had ignored repeated requests to stop.

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."

U.S. District Judge Maxine Chesney on March 9 granted Amazon's request for a preliminary order blocking Perplexity AI's agents from accessing the e-commerce giant's platform.

"Enjoining the use of Perplexity’s signature product on one of the Internet’s most important websites would cause devastating harm to the company and consumers alike," Perplexity told the 9th Circuit in its request to pause the order.

The appeals court on Monday granted Perplexity's motion for an administrative stay of the order while the circuit considers its request.

The case is Amazon.com Services LLC v. Perplexity AI Inc, 9th U.S. Circuit Court of Appeals, No. 26-1444.

For Amazon: Moez Kaba, Hagan Scotten, ⁠Christine Woodin, Lisa Chen and Youzhihang Deng of Hueston Hennigan

For Perplexity: John Quinn, Daniel Posner and Jonathan Kim of Quinn Emanuel Urquhart & Sullivan
