When the Secret Isn't the Wrong: Angelica Textile Services v. Park and the Limits of CUTSA Displacement

The Fourth District reversed summary judgment to hold that California's trade-secret statute does not displace breach-of-contract, fiduciary-duty, conversion, and unfair-competition claims that rest on conduct independent of any misappropriation.

If K.C. Multimedia opened the door to California’s trade-secret supersession doctrine and Silvaco pushed it toward its outer wall, Angelica Textile Services, Inc. v. Park, No. D062405 (Cal. Ct. App., 4th Dist., Div. 1, Oct. 15, 2013), drew the line back. Writing for the Fourth District, Acting Presiding Justice Benke reversed a grant of summary judgment that had dismissed a former employer’s tort and contract claims as displaced by the California Uniform Trade Secrets Act (CUTSA), holding that the statute does not absorb claims whose factual basis is independent of the misappropriation theory. The decision is the doctrine’s essential counterweight: it confirms that supersession is a rule about overlapping facts, not about overlapping defendants, and it preserves the ordinary law of employee disloyalty against a creeping reading of CUTSA that would have swept it away.

At a glance

Angelica Textile Services operated a large-scale commercial laundry serving hospitals and other medical facilities. Jaye Park, a longtime employee who had risen to a vice-president role, allegedly spent his final months at the company planning and financing a competing laundry business while still on Angelica’s payroll—negotiating for customers, arranging facilities, and taking company documents. After Park left and the competitor launched, Angelica sued, asserting trade-secret misappropriation under CUTSA alongside claims for breach of contract, breach of fiduciary duty, unfair competition, interference with business relationships, and conversion.

The trial court granted summary adjudication against the non-CUTSA claims, reasoning that they were “preempted” because they arose from the same facts as the misappropriation claim. A jury then found that the documents Park took were not trade secrets, defeating the CUTSA claim. Angelica appealed the dismissal of its other theories. The Court of Appeal reversed, holding that the non-CUTSA claims were not displaced because each rested on conduct distinct from any taking of a trade secret—and, as to conversion, observing that a claim cannot be displaced by CUTSA when the property at issue is not a trade secret at all.

Displacement turns on the facts, not the overlap

The court’s analytical starting point is the now-familiar principle that CUTSA, through Civil Code section 3426.7, supersedes common-law claims grounded in the misappropriation of a trade secret. But Angelica Textile sharpens the operative question. A claim is displaced, the court held, only if it depends on the same facts as the trade-secret claim “without other supporting allegations.” The inquiry is whether the non-CUTSA cause of action would exist, and be wrongful, even if no trade secret were ever in play.

Measured against that standard, Angelica’s claims survived. The gravamen of its case against Park was not merely that he took documents; it was that he breached duties of loyalty and contract by organizing and financing a competing business while still employed, and by diverting business opportunities that belonged to Angelica. That conduct—competing while employed, breaching a noncompetition or loyalty obligation, usurping corporate opportunities—is independently tortious under settled California law regardless of whether any information Park took qualified as a trade secret. Because the breach-of-fiduciary-duty, breach-of-contract, unfair-competition, and interference claims drew on this independent factual nucleus, CUTSA did not reach them.

The decision thus reframes supersession as a screen against duplication, not a grant of immunity. A faithless employee does not acquire a shield against the ordinary law of disloyalty simply because some of his misconduct also happens to involve confidential information. The presence of a trade-secret claim in the complaint does not contaminate every other theory that shares a defendant.

Conversion and the “not a trade secret” corollary

The conversion claim received distinct treatment that has become one of the case’s most cited points. The jury had found that the documents Park took were not trade secrets. From that finding the court drew a clean inference: if the property converted is not a trade secret, then CUTSA—which by its terms governs trade secrets—cannot displace a conversion claim over that property. Displacement presupposes that the claim concerns a trade secret; where the factfinder has determined the information is not one, there is nothing for the statute to occupy.

This corollary sits in evident tension with the broad reading of Silvaco, under which CUTSA may displace claims premised on confidential-but-non-secret information. The two decisions are not formally irreconcilable—Angelica Textile emphasizes the independent factual basis of the conversion claim and the jury’s specific finding, while Silvaco addresses claims that depend on the taking of information as their whole theory—but the gap between them is precisely where much California litigation now lives. Practitioners read Angelica Textile as confirming that a conversion claim over tangible documents or property is not displaced merely because the documents also contained, or were alleged to contain, confidential data.

A doctrine of two postures

Read together, the California trilogy describes supersession as a single test applied from two postures. K.C. Multimedia and Silvaco show the test cutting against plaintiffs who repackage a misappropriation claim as conversion, conspiracy, breach of confidence, or unfair competition without adding any independent wrong. Angelica Textile shows the same test protecting plaintiffs whose claims rest on genuinely separate conduct—disloyal competition, breach of an enforceable promise, usurpation of opportunity—even when a trade-secret claim travels alongside. The unifying principle is factual independence. The doctrine asks not “do these claims share a defendant or a dispute?” but “does this claim depend on the misappropriation of a trade secret for its wrongfulness?”

That framing also explains why Angelica Textile is so often paired with the supersession-friendly cases in briefing: it supplies the affirmative roadmap for surviving a displacement challenge. Plead the independent duty, allege the conduct that would be tortious absent any secret, and segregate those facts from the misappropriation theory.

Open questions

The decision leaves real uncertainty at its seams. It does not reconcile its conversion holding with the broad reading of Silvaco regarding non-trade-secret information, and the two lines continue to be cited against each other. It does not specify how much factual independence is enough—whether a single allegation untethered to the secret rescues a claim, or whether the claim’s center of gravity must lie outside the misappropriation. And because the case turned in part on a jury’s finding that the documents were not trade secrets, it offers limited guidance on how a court should resolve displacement at the pleading or summary-judgment stage, before the trade-secret status of the information has been adjudicated. A defendant who concedes nothing about secrecy may face a different sequencing problem than Park did.

Implications

  • Independent conduct defeats displacement. Claims for disloyal competition, breach of fiduciary duty, breach of contract, and usurpation of corporate opportunity survive CUTSA when they would be wrongful even absent any trade secret.
  • A “not a trade secret” finding can unlock conversion. Where the factfinder determines the information was not a trade secret, CUTSA cannot displace a conversion claim over the same property.
  • Plead the duty and segregate the facts. Plaintiffs should anchor each non-CUTSA claim in conduct independent of the taking and keep those allegations distinct from the misappropriation theory.
  • Supersession is a screen, not a shield. The doctrine prevents duplicative recovery; it does not immunize faithless employees from the ordinary law of loyalty.
  • Watch the Silvaco tension. The conversion corollary sits uneasily with the broad non-trade-secret reading of Silvaco; outcomes can turn on which line a court follows.

Frequently asked questions

Does Angelica Textile overrule the California supersession doctrine? No. It applies the same “same nucleus of facts” test established in K.C. Multimedia, but from the plaintiff’s side, confirming that claims with an independent factual basis are not displaced. It refines the doctrine rather than rejecting it.

Why did the conversion claim survive when the trade-secret claim failed? Because the jury found the documents were not trade secrets. CUTSA governs trade secrets; if the property at issue is not a trade secret, there is no CUTSA claim for the conversion theory to duplicate, so displacement does not apply.

What is the practical lesson for employers suing departing employees? Build the complaint around independently wrongful conduct—breach of a loyalty or contractual duty, competing while employed, diverting opportunities—rather than relying solely on the taking of information. Those claims survive even if the trade-secret theory ultimately fails.
