When Trade Secret Claims Become Non-Competes by Another Name

On June 15, 2026, a federal court in San Francisco dismissed xAI’s trade secret claims against OpenAI with prejudice. Judge Rita Lin was direct:

“In essence, xAI equates asking a candidate about their prior work experience with encouraging the candidate to divulge trade secrets obtained during that prior work experience.”

And on the exposure risk:

“To hold otherwise would potentially expose employers to liability any time they inquire about a candidate’s past work.”

The case had every headline ingredient — artificial intelligence (AI), departing engineers, Grok-related secrets, Elon Musk versus Sam Altman. The doctrine that defeated it was not new. It was FLIR Systems, Inc. v. Parrish, 174 Cal.App.4th 1270 (2009), applied to 2026 facts. And the dismissal came with prejudice for a reason that sits at the heart of this article: xAI had sought to keep the case alive long enough to obtain, in discovery, the evidence it lacked at filing. The court refused, holding that a plaintiff “was required to have completed its investigation of its claims before filing suit, not after.”

Put differently: the court did not treat a job interview as a trade secret extraction ceremony.

California Is Not PepsiCo

PepsiCo, Inc. v. Redmond, 54 F.3d 1262 (7th Cir. 1995), made “inevitable disclosure” famous: a former employee’s new competitive role would necessarily cause reliance on the prior employer’s confidential information. California rejected that approach in Whyte v. Schlage Lock Co., 101 Cal.App.4th 1443 (2002). Applying inevitable disclosure, the court held, would impose “not merely an injunction against the use of trade secrets, but an injunction restricting employment” — a noncompete in everything but name. Business and Professions Code section 16600 was written with that employee in mind.

California’s noncompete ban creates a predictable litigation pressure point. When employers cannot restrain competition directly, trade secret claims become the battlefield. That is not inherently wrong — real misappropriation causes real harm and the California Uniform Trade Secrets Act (CUTSA) provides real remedies. The problem is when suspicion, access, and employee mobility get filed as a complaint before the plaintiff has evidence.

Courts have long recognized that danger. In Mattel, Inc. v. MGA Entertainment, Inc., the court explained that California requires trade secret plaintiffs to identify alleged secrets with particularity “to prevent employers from using trade secret law as a weapon against employee mobility.” That is the prefiling rule in plain English: identify the secret before suing. Do not file first and ask the court to find the secret for you.

FLIR: Fear Is Not a Fact

FLIR Systems sued former officers who planned to start a competing venture after FLIR acquired their company for $185 million. The theory was not that the defendants had used FLIR’s trade secrets. It was that they possessed valuable knowledge and would inevitably use it in competition.

At trial, it was undisputed: no funding, no employees, no facility, no product, no customers. FLIR’s own CEO explained the lawsuit from the stand:

“[W]e can’t tolerate a direct competitive threat by Bill [Parrish] and Tim [Fitzgibbons].”

That is not a trade secret theory. It is a competitive concern. The Court of Appeal affirmed $1,641,216.78 in attorney’s fees under Civil Code section 3426.4.

FLIR is often treated as a merits case. It is equally a prefiling-investigation case. The court examined what the plaintiff actually had when it sued. The answer was fear, not evidence.

FLIR is the simple rule: fear is not a fact.

The Published Fee-Warning Cases

SASCO v. Rosendin Electric, Inc., 207 Cal.App.4th 837 (2012), sharpened the evidentiary rule. SASCO lost a bid to a competitor that had hired its former employees and sued for misappropriation without forensic investigation. The court affirmed a $484,943 fee award and stated the thesis in a single sentence:

“Speculation that the individual employees must have taken trade secrets from SASCO based on their decision to change employers does not constitute evidence of misappropriation.”

The defendant, the court added, is not required to conclusively prove a negative. The defendant does not have to prove that a ghost never existed.

In Cypress Semiconductor Corp. v. Maxim Integrated Products, Inc., 236 Cal.App.4th 243 (2015), Cypress sued after Maxim recruited its engineers. The supposed trade secret — the identities of Cypress’s touchscreen team — was assembled from a single industry website and published patent records. The court called the theories “not merely specious, but nonsensical.” Recruiting a competitor’s employees, without more, is lawful in California. The fee award was affirmed.

Cypress reduces the point to common sense: recruiting is not a trade secret tort.

Plus One for Creativity: FormFactor and the Clinical Psychologist

If FLIR rejected inevitable disclosure, FormFactor showed how far a plaintiff might go to repackage it. In FormFactor, Inc. v. Micro-Probe, Inc., No. C 10-03095 PJH (N.D. Cal. 2012), the plaintiff could not identify any actual misappropriation by a former vice president who had taken a similar role at a competitor. So, it offered a clinical psychologist. The expert opined that, from “a neurological and physiological standpoint,” the former employee “cannot do anything but use” FormFactor’s information, given the similarity of his new job and the length of his prior tenure. The court excluded the opinion as irrelevant under Rule 702 — testimony about an employee’s “memory and brain function” proves nothing about misappropriation — and recognized the move for what it was: an attempt to “insert the ‘inevitable disclosure’ doctrine into [the] motion without actually naming it.”

Neuroscience is not evidence of misappropriation. Nor is any other theory that substitutes a defendant’s personal characteristics — psychological, behavioral, or otherwise — for evidence of what the defendant actually did.

Skill, Memory and Experience Are Not Trade Secrets

California courts have consistently held that an employee does not leave as an empty vessel. In Hooked Media Group, Inc. v. Apple Inc., 55 Cal.App.5th 323 (2020), the court held that “mere possession of information is not enough to establish improper acquisition” and that misappropriation requires “some element of wrongfulness” beyond knowledge, speed, or technical proficiency. Similarly, in AMN Healthcare, Inc. v. Aya Healthcare Services, Inc., 28 Cal.App.5th 923 (2018), nurse contact information the plaintiff claimed as a trade secret was already in the defendant’s own database and on public sources. Confidentiality is not the same as secrecy.

Employees do not become radioactive because they learned things at a prior job.

California Is Not Anti-Trade-Secret

California courts act decisively when the evidence is real. The distinction from FLIR and SASCO is not competitive hiring. It is forensic evidence of actual conduct gathered before filing.

In Mattson Technology, Inc. v. Applied Materials, Inc., 96 Cal.App.5th 1149 (2023), the evidence included self-emailing marked confidential documents before departure, false exit statements in two interviews, post-suit deletion of emails, and a pattern of seventeen departing employees wiping company phones. The Court of Appeal affirmed a preliminary injunction against both the engineer and the new employer.

In Applied Medical Distribution Corp. v. Jarrells, 100 Cal.App.5th 556 (2024), a departing employee built a folder titled “Good Stuff,” transferred it to a thumb drive, uploaded it to his new employer’s computer, and wiped the old laptop. A jury found both the employee and the new employer — a named recipient — liable for misappropriation. A permanent injunction was affirmed even without proven damages.

California protects secrets. It does not subsidize separation anxiety.

The Fee Risk Is Real

CUTSA’s bad-faith provision, Civil Code section 3426.4, shifts fees when a claim is objectively specious and subjectively maintained in bad faith. FLIR, SASCO, and Cypress are the published examples. A review of more than 50 additional unpublished decisions confirms the pattern: plaintiffs who proceed on suspicion, mobility, or broad categories without forensic evidence do not merely lose. They pay.

A Prefiling Checklist

Before filing a CUTSA case against a departing employee, California counsel should work through at least the following.

1. What is the actual trade secret? Not the category. Not “technical data” or “customer information.” Identify the specific information. California Code of Civil Procedure section 2019.210 requires reasonable particularity before discovery begins. Do that work before filing.
2. Is it actually secret and economically valuable? Check patents, publications, marketing materials, and what the defendant independently possessed. A claimed secret already in the public domain or in the defendant’s own database is not protectable.
3. What reasonable measures actually protected it? NDAs and access controls matter. So do contrary facts: broad sharing, personal device use, casual emailing. Courts look at actual practices, not labels.
4. What evidence shows improper acquisition, use, disclosure, or imminent threat? This is the core question. Access is not enough. Possession is not enough. Employment by a competitor is not enough. The plaintiff needs conduct: copying, downloading, forwarding, lying about retention, wiping devices. Without that conduct, the plaintiff is building a FLIR.
5. Is there a named recipient? Strong cases have a concrete recipient — a competitor, new employer, or customer who received the information. Theoretical future disclosure is not a threat. It is speculation.
6. Have lawful explanations been ruled out? Public information, general skill, independent knowledge, authorized access, and preexisting relationships are all lawful. SASCO filed without asking whether the competitor might have won the bid legitimately. That cost nearly half a million dollars.
7. Is the requested relief actually a noncompete? An injunction against use or disclosure of a specific identified trade secret is legitimate. An injunction preventing employment or competition because the employee knows too much is a noncompete. California courts will call it one.
8. Would the case exist if the employee were permitted to compete? This is the FLIR question. If the case exists only because the employee is knowledgeable, valuable, and working for a competitor, it is not ready. It is a noncompete by another name — and it comes with a fee award attached.

The Right Question

The best prefiling question is the simplest: “If this employee were allowed to work, consult, and compete freely using general skill and experience, what specific trade secret would still be at risk — and what did the defendant actually do with it, as distinct from merely knowing it, possessing it, or working in a competitive role?”

If the answer is concrete, the case may be ready.

If the answer is access, suspicion, fear, or mobility, 17 years of California authority from FLIR through xAI v. OpenAI have given the warning: that is not a trade secret case. It is a noncompete by another name.
