Palantir Sues Former Engineers for Trade Secret Theft

Palantir Technologies, a leading data analytics and artificial intelligence firm, has filed a lawsuit against two of its former senior AI engineers. The lawsuit, filed in New York’s Southern District Court in late October 2025, accuses the engineers of stealing trade secrets and confidential documents to establish a competing startup named Percepta. This case underscores significant concerns about intellectual property protection in the AI industry.

Background: The Accusation and Legal Claims

Palantir’s lawsuit targets two former AI engineers, one of whom is a co-founder of Percepta, a newly launched AI transformation company backed by the venture capital firm General Catalyst. Palantir alleges that these engineers engaged in deceptive practices, such as emailing confidential documents to personal accounts and accessing them via personal devices immediately after resigning. This conduct, Palantir contends, facilitated the establishment of Percepta as a “copycat” business leveraging Palantir’s proprietary AI technology.

The lawsuit emphasizes:

Breach of noncompete agreements by the former employees, though not all ex-Palantir staff at Percepta are bound by such agreements.
The use of stolen documents to build technology and products that mirror Palantir’s offerings.
A forensic investigation by Palantir that uncovered evidence of “highly confidential documents” being transferred to personal devices immediately following resignation notices.

Palantir is seeking an injunction to prevent further use of its proprietary information and the return of all misappropriated documents.

Percepta and General Catalyst: A Rising AI Startup

Percepta was recently unveiled by General Catalyst, a venture capital firm known for aggressive investments and strategic expansions. General Catalyst’s involvement adds significant market weight to Percepta, positioning it as a serious contender in enterprise AI transformation. However, the lawsuit threatens to overshadow Percepta’s launch and raise questions about the startup’s foundation and ethical practices.

Industry Context: Growing Litigation Over AI Trade Secrets

This case exemplifies a broader trend of litigation within the AI and tech startup ecosystem focusing on intellectual property theft and employee mobility disputes. As AI technologies become a central competitive asset, companies increasingly emphasize protecting trade secrets amid aggressive hiring and poaching of talent.

The enforceability of noncompete clauses remains a contentious issue, as many jurisdictions limit their scope.
Palantir’s $471 billion market valuation underscores the substantial stakes involved in safeguarding proprietary AI models and data analytics tools.
Despite legal disputes, venture capital funding in AI startups remains robust, with investors prioritizing innovation and market potential over litigation risks.

Potential Impact and Outlook

The lawsuit could have several implications:

For Palantir, it is a defensive move to protect its core intellectual property and deter similar incidents.
For Percepta and General Catalyst, the lawsuit may hinder fundraising efforts and damage reputations if the allegations hold.
For the AI industry at large, the case highlights the challenges of balancing employee mobility with corporate IP protection in a field where knowledge transfer is rapid and competition intense.

Legal experts note that Palantir’s claim of a “copycat” startup will be difficult to prove conclusively, as many AI companies inevitably develop overlapping technologies. The outcome will likely hinge on demonstrating direct misuse of confidential information rather than general competitive innovation.

As AI becomes critical to enterprise transformation, protecting proprietary knowledge remains a contentious and closely watched issue. The case will be a notable test of noncompete enforcement and trade secret law in the evolving AI landscape.
