US court overturns Amazon injunction aimed at Perplexity AI’s Comet browser

A US appeals court has overturned an injunction obtained by Amazon against Perplexity AI, according to reporting on the dispute. The legal fight centers on Perplexity’s Comet browser, an AI assistant embedded in the browsing experience that can carry out tasks for users rather than simply summarizing information.

In the underlying complaint described in coverage of the case, Amazon challenged aspects of how the Comet browser performs actions that can include purchasing-related activity on Amazon’s site. The court’s decision to overturn the injunction means the restrictions Amazon had sought against Perplexity’s product are no longer in effect, at least for the stage addressed by the ruling.

Perplexity’s Comet is presented as a browser experience that uses an AI system to guide and execute user goals inside web workflows. That includes, as described in the reporting, the ability to perform tasks with retail websites, where the assistant may help coordinate steps that resemble e-commerce usage rather than passive reading.

Amazon, which is both a marketplace operator and a technology platform provider, has spent years tightening rules around automated access, content use, and how third-party tools interact with its shopping and retail pages. While this case is not only about automation in the abstract, Amazon’s move to seek an injunction suggests the company viewed Perplexity’s functionality as crossing a line from information retrieval into commercially meaningful actions.

The overturned injunction is also likely to draw attention because it touches a fast-growing category of AI tools designed to take action online. Many such products promise convenience, but they also raise legal questions about scraping, browsing without permission, and whether an AI agent’s ability to complete steps on third-party websites changes the risk profile compared with traditional search.

In broader market context, the dispute reflects how large platforms are responding to AI assistants that blur boundaries between searching, summarizing, and transacting. For Amazon, these questions are especially sensitive because the company’s retail system is built around controlled user flows, pricing and availability displays, and protections against bot-driven activity.

Still, important details remain unclear based on the limited information in the published report. The coverage summarized the general subject matter, namely the Comet browser’s task execution and its connection to Amazon shopping, but it did not provide all of the legal reasoning behind the appeals court’s decision, the scope of the injunction before it was overturned, or what specific conduct the court found insufficient to justify the order.

What to watch next is whether Amazon seeks further review and whether the parties clarify, through additional filings or follow-on court actions, what specific Comet behaviors are now permitted. The trajectory of this case could shape how other AI assistant developers think about building “agentic” browsing features that interact with major commercial websites.
