a bot maybe accessed a former employer's trade secrets; larger trade secret/false advertising issues ensure employer's victory

Capconvert, LLC v. Brown, 2026 WL 1471880, No. 26-cv-02149-CRB (N.D. Cal. May 26, 2026)

Capconvert sued its former employee Brown primarily over alleged misappropriation of Capconvert’s trade secrets and confidential information for use in a competing business venture involving search engine optimization (SEO), generative engine optimization (GEO) (ugh), answer engine optimization (AEO) (double ugh), and paid ad management services. The court followed an earlier TRO by granting a preliminary injunction. I will focus only on the Lanham Act/California FAL claims, except to note that the record contains a document, apparently a prompt to an AI agent, stating “This is the most important rule you have. You violated it on February 26th, 2026, and it nearly destroyed Ben’s career,” purportedly intended to make it “abundantly clear to any agent that I was working with ... to not access any Capconvert ... file.” However, another bot allegedly “disputed” that any such access occurred. Where is the truth? It will likely take many, many expensive hours of lawyer billing time to identify. So if you’re looking for a litigated case to scare people about AI and trade secrets—it has arrived.

Brown’s competing service, Signyl claims to offer the same services as Capconvert. Brown’s LinkedIn page described him as “Managing Partner” of Capconvert, though that was never his role or title. It stated that he worked on Capconvert’s Rankily product, but he did not. The Signyl website states “200+ Brands managed $50M+ Ad spend optimized,” which cannot be true as Signyl had only existed for one month. Brown had no relevant experience in SEO prior to his time at Capconvert, and while there, only brought in one client. He did not manage 200+ Brands or optimize a “$500M+ Ad spend.” The Signyl website also appears to misrepresent Signyl’s performance metrics.

Brown  contended that “the metrics displayed on that site did not relate to Capconvert work” but were “derived from my work predating Capconvert” and that “any public statements I made about my experience were intended to refer to my own prior professional background and track record at Google.”

The court found many of the website claims “plainly false.”  “Signyl has no clients, let alone 200+ clients…. A banner that ‘runs across the front page of the Signyl.agency’ making claims about particular experience necessarily suggests that the experience is that of the company whose website it is. Those claims are false, at least as to Signyl.” Likewise, the claims were material: “Representations of experience across relevant services and with hundreds of brands would likely be material to prospective clients seeking those services.”

However, while the LinkedIn statements were false, Capconvert hadn’t yet demonstrated how it was likely to be injured as a result.

Irreparable harm as to the false advertising was presumed under the Lanham Act, and shown for trade secrets.  “Signyl has only been operational for a couple of months; that it has not yet poached any business from Capconvert using Capconvert’s trade secrets and confidential/proprietary information or by misrepresenting itself on its website does not mean that Signyl is not likely to cause harm going forward.” Likewise, on the balance of equities, the court commented: “Even if an injunction amounted to a shut down, just how much would a preliminary injunction shut down?”
