A U.S. federal court has issued a temporary order requiring Perplexity AI Inc. to halt its Comet web browser agent from making purchases on Amazon.com Inc.'s marketplace. The ruling is a significant development in an ongoing legal dispute between the e-commerce giant and the AI startup.
The case began in November when Amazon filed a lawsuit against Perplexity AI, accusing the company of computer fraud. Amazon alleges that Perplexity's Comet agent accesses password-protected user accounts with the user's permission but without authorization from Amazon, a violation of its terms of service.
Presiding Judge Maxine Chesney in San Francisco federal court stated that Amazon presented strong evidence to support its claims. An Amazon spokesperson confirmed the preliminary injunction helps maintain a trusted shopping experience for its customers.
This court decision highlights a growing tension between AI-driven automation tools and the proprietary platforms they interact with. The ruling temporarily favors the platform owner's right to control access to its systems, even when users grant permission to third-party agents.
The outcome of this case could set a legal precedent for the use of AI shopping bots and other automated web agents, potentially influencing the future development of AI-powered consumer tools and the security policies of major online retailers.
The order is a temporary measure while the court fully examines the legality of Perplexity's actions. Perplexity has one week to appeal the decision before it takes full effect. The case will be closely watched as it will help define the legal framework for interactions between AI agents and private digital platforms.
Q: Why did Amazon sue Perplexity AI?
A: Amazon accused Perplexity AI of computer fraud, alleging its Comet agent accessed password-protected user accounts without Amazon's authorization.
Q: What is the immediate effect of the court order?
A: Perplexity must temporarily stop its Comet browser agent from accessing password-protected sections of Amazon's systems, including Prime subscriber accounts, and must destroy any copies of Amazon's data it possesses.
Q: Is this ruling final?
A: No, it is a temporary order. The ruling is suspended for one week to allow Perplexity AI to appeal, and the broader legal case will continue.
