裁判所、AmazonによるPerplexityエージェント禁止を覆す
米控訴裁は、PerplexityのAIエージェントによるAmazonへのアクセスを阻止する差し止め命令を覆し、プラットフォームにアクセスしているのはAIではなくユーザーだと判断した。この決定はエージェントの合法性に関する先例となる。
the 9th us circuit court of appeals overturned a preliminary injunction that barred perplexity from operating its ai shopping agents on amazon, determining that users accessing their own accounts via agents does not constitute fraud by the startup. the court rejected amazon's argument that the ai company was the one accessing the computer without authorization, a distinction that validates the 'user attribution' defense for agentic ai. amazon, which called the agents a security risk and accused perplexity of ignoring cease-and-desist orders, stated it is evaluating next steps while the underlying lawsuit proceeds. this ruling establishes a critical precedent for the emerging agent economy, defining the legal boundary between automated tools and unauthorized computer access.
