美国上诉法院推翻禁令，Perplexity AI 购物智能体重返 Amazon

美国上诉法院推翻了针对Perplexity的禁令。理由是：用户访问的是亚马逊，而不是这家人工智能公司。

位于旧金山的美国第九巡回上诉法院推翻了一项禁令，该禁令阻止Perplexity在亚马逊平台上使用其智能AI购物工具。路透社报道：https://www.reuters.com/business/retail-consumer/amazon-loses-us-court-ban-perplexitys-ai-shopping-tools-2026-08-04/，法院认定，亚马逊在声称Perplexity的AI代理违反联邦计算机欺诈法的诉讼中，获胜的可能性不大。

决定性因素是归属问题。法律禁止在未经许可的情况下访问计算机并获取信息。但上诉法院认为，是用户通过代理访问了亚马逊的平台，而不是Perplexity自身。法院在这一点上支持了初创公司的观点。

这是美国联邦上诉法院关于AI代理是否可以合法代表用户访问在线平台的首个裁决。答案对整个领域都有影响。智能代理系统可以计划、推理并在有限的人类监督下完成任务。它们可以在网络上浏览、购物并完成交易。

亚马逊不接受此次败诉。“我们对今天关于初步禁令的裁决表示尊重但不同意，”一位发言人表示，并补充称，公司仍然充满信心并在评估应对方案。“我们仍然对我们的案件充满信心，并正在评估下一步行动。”Perplexity发言人Jesse Dwyer表示，“Perplexity将继续为互联网用户选择任何AI的权利而斗争。”

去年11月，亚马逊起诉Perplexity，指控该初创公司通过其Comet浏览器及内置的AI代理秘密访问亚马逊客户的私人账户。该代理可以代表用户登录购物账户并下订单。亚马逊的诉状指出存在安全风险，并声称Perplexity无视其多次要求停止的请求。初创公司称该诉讼毫无根据，是“赤裸裸的企图”阻止亚马逊客户使用Comet，因为AI代理“没有眼睛来看到亚马逊对用户进行的普遍广告。”

今年三月，加利福尼亚的一家联邦法院暂时禁止Perplexity在亚马逊上使用能动型AI。法官Maxine Chesney发现“有力证据”显示Perplexity在用户许可的情况下访问受密码保护的账户，但未获得亚马逊的授权。该初创公司还被命令删除亚马逊数据的副本。该禁令现在已无效，但相关案件尚未裁决。

亚马逊曾表示，第三方AI必须透明运行并遵守既定的API，指出其自身工具如“为我购买”和“Rufus”助手。Perplexity CEO Aravind Srinivas称其为“欺凌”，并认为代表用户行动的代理应享有与人类用户相同的权利。两家公司之间的商业关系为争议增加了另一层复杂性。Perplexity是AWS客户，承诺金额达数亿美元，Jeff Bezos也是该初创公司的投资者之一。Ad DEC_D_Incontent-2

A US appeals court has overturned the injunction against Perplexity. The reasoning: users access Amazon, not the AI company.

The 9th US Circuit Court of Appeals in San Francisco has overturned an injunction that blocked Perplexity from using its agentic AI shopping tools on Amazon's platform. According to Reuters：https://www.reuters.com/business/retail-consumer/amazon-loses-us-court-ban-perplexitys-ai-shopping-tools-2026-08-04/, the court found that Amazon was unlikely to succeed on its claim that Perplexity's AI agents violated a federal computer fraud law.

The deciding factor was a question of attribution. The law prohibits accessing computers and obtaining information without permission. But the appeals court concluded that it was the users who accessed Amazon's platform through the agents, not Perplexity itself. The court sided with the startup's argument on that point. Ad

This is the first ruling by a US federal appeals court on whether AI agents can lawfully access online platforms on behalf of users. The answer matters for an entire field. Agentic systems plan, reason, and carry out tasks with limited human oversight. They browse, shop, and complete transactions across the web. Ad DEC_D_Incontent-1

Amazon isn't accepting the loss. "We respectfully disagree with today's decision on the preliminary injunction," a spokesperson said, adding that the company remains confident and is weighing its options. "We remain confident in our case and are evaluating our next steps." Perplexity spokesperson Jesse Dwyer said, "Perplexity will continue to fight for the right of internet users to choose whatever AI they want."

Amazon sued Perplexity in November, accusing the startup of covertly accessing private Amazon customer accounts through its Comet browser and the AI agent built into it. The agent can log into shopping accounts and place orders on behalf of users. Amazon's complaint alleged security risks and claimed Perplexity had ignored repeated demands to stop. The startup called the lawsuit baseless and a "bald attempt" to keep Amazon customers away from Comet, because AI agents "don't have eyeballs to see the pervasive advertising Amazon bombards its users with."

In March, a federal court in California temporarily barred Perplexity from using agentic AI on Amazon. Judge Maxine Chesney found "strong evidence" that Perplexity accessed password-protected accounts with users' permission but without Amazon's authorization. The startup was also ordered to delete copies of Amazon data. That injunction is now void, but the underlying case hasn't been decided.

Amazon had argued that third-party AI must operate transparently and respect established APIs, pointing to its own tools like "Buy For Me" and the "Rufus" assistant. Perplexity CEO Aravind Srinivas called it "bullying" and argued that agents acting on behalf of users should have the same rights as human users. The business ties between the two companies add another layer to the dispute. Perplexity is an AWS customer with commitments in the hundreds of millions of dollars, and Jeff Bezos is among the startup's investors. Ad DEC_D_Incontent-2
