When 'Everything Is a Trade Secret' Is Nothing: Sysco Machinery v. DCS USA

The Fourth Circuit affirms dismissal of a DTSA complaint that defined its trade secrets three ways, holding that sweeping definitions fail the particularity that the statute's secrecy and value elements presuppose.

In Sysco Machinery Corp. v. DCS USA Corp., No. 24-1675 (4th Cir. July 9, 2025), a unanimous panel of the United States Court of Appeals for the Fourth Circuit (Wilkinson, J., joined by Gregory and Richardson, JJ.) affirmed the dismissal of a trade-secret misappropriation complaint that, in the court’s words, suggested “nearly Sysco’s entire business is a trade secret.” The decision is a compact but consequential statement of what a plaintiff must do at the pleading stage to put a trade secret before a federal court, and it situates the Fourth Circuit on a recognizable side of an emerging divide over how early, and how precisely, a claimant must say what it claims to own. For practitioners, Sysco is less a doctrinal innovation than a disciplined application of Twombly and Iqbal to the unusual proof structure of a trade-secret claim—one in which the asset’s very existence depends on facts the plaintiff alone can supply.

At a glance

The procedural posture matters because it shapes the holding. Sysco Machinery, a Taiwanese manufacturer of rotary die-cutting equipment, alleged that former employees departed to form a competitor, Cymtek Solutions, and that DCS USA—Sysco’s former U.S. distributor—then sold Cymtek-built machines incorporating Sysco’s confidential information. The case reached the Fourth Circuit after a litigation history the panel found telling: Sysco filed in the Eastern District of North Carolina, voluntarily dismissed, refiled in the District of Massachusetts (dismissed), and then returned to North Carolina with claims under the federal Defend Trade Secrets Act (DTSA), the North Carolina Trade Secrets Protection Act, the Copyright Act, and state unfair-competition and tortious-interference theories.

The district court dismissed and denied leave to amend. The Fourth Circuit affirmed across the board. On the trade-secret counts, the panel held that Sysco had not plausibly alleged either the existence of a valid trade secret or its misappropriation. The court treated the DTSA and the North Carolina statute as “substantially identical” in their operative definitions, so a single analysis disposed of both. The copyright and remaining claims were affirmed on waiver grounds for inadequate appellate briefing, and the denial of leave to amend was upheld as a sound exercise of discretion given Sysco’s repeated, materially identical filings.

What qualifies as a trade secret—and why the definition does the work

Both statutes define a trade secret by reference to two substantive conditions: the information must derive independent economic value from not being generally known, and the owner must take reasonable measures to keep it secret. Sysco is useful precisely because it treats those conditions not as boilerplate elements to be recited but as facts a complaint must make plausible. The panel framed trade-secret value as a function of “exclusive access”—the competitive edge that comes from holding information rivals do not have. That framing has a corollary the court enforced bluntly: information that has been publicly disclosed cannot qualify, because disclosure dissolves the exclusivity on which value rests.

The point became concrete through Sysco’s own pleading. Among the materials Sysco identified as protected were twenty-three technical drawings it had deposited, unredacted, with the U.S. Copyright Office. The court held that public registration “extinguished” any trade-secret status in those drawings: a registrant who places technical drawings in the public record cannot simultaneously claim that the same drawings remain secret. The observation is not novel—courts have long recognized the tension between copyright’s disclosure regime and trade secrecy—but its placement in a particularity analysis is instructive. It shows that the question “what qualifies as a trade secret” cannot be answered in the abstract; it can only be answered against a specific identification of the information, because secrecy and value are properties of particular information, not of a category.

Particularity as the gatekeeper to the statutory elements

The heart of Sysco is its account of why identification with “sufficient particularity” is a pleading requirement rather than a discovery nicety. Drawing on the Fourth Circuit’s own Trandes Corp. v. Guy F. Atkinson Co., 996 F.2d 655 (4th Cir. 1993), the panel reasoned that a plaintiff must allege both a valid trade secret and its misappropriation, and that the validity inquiry is impossible to conduct unless the court can tell what the asserted secret is. Particularity, in the court’s framing, serves two audiences. It allows the defendant to “delineate that which he is accused of misappropriating,” and it allows the court “to determine whether the plaintiff has plausibly satisfied the reasonable secrecy and independent economic value requirements.” Identification, in other words, is the predicate for everything else: one cannot assess whether reasonable measures protected the information, or whether it carries independent value, without first knowing which information is at issue.

Measured against that standard, Sysco’s complaint failed for a structural reason the opinion dwells on. Sysco offered three different definitions of its trade secrets, “each broader than the last,” together sweeping in proprietary, confidential, financial, and operational information. The panel characterized the definitions as “sweeping and conclusory” and concluded that they implied the protection of nearly the entire enterprise. That overbreadth is not a stylistic complaint. A definition that encompasses everything identifies nothing: it gives the defendant no notice of what conduct is forbidden, and it gives the court no anchor for testing secrecy or value. The court also tied particularity to the plausibility inquiry directly, observing that a claim that an entire business is secret is “unlikely to be true in practice”—a recognition that the more capacious the asserted secret, the less believable the assertion becomes under Iqbal.

The panel grounded the requirement in a candid policy rationale: trade-secret litigation “has the potential to seriously disrupt ordinary business relationships.” Distributors, suppliers, and departing employees all operate in a world of lawful information flow, and an under-specified claim threatens to convert routine commercial conduct into actionable misappropriation. Particularity polices that risk at the threshold.

Independent economic value and the limits of “improper means”

Sysco reinforces that independent economic value is inseparable from misappropriation by improper means. The court emphasized that misappropriation requires acquisition, disclosure, or use through a “breach of a duty of trust or confidentiality.” Information obtained through lawful channels, absent any such duty, is not misappropriated “even if [the] conduct seems objectionable.” Sysco never alleged that DCS owed it a confidentiality obligation as to the asserted secrets, nor did it explain how DCS—acting in its ordinary capacity as a distributor—acquired, disclosed, or used them improperly. The absence of a duty was fatal independent of the particularity defect: even a perfectly identified secret yields no claim against a defendant who came by the information legitimately.

Open questions

Sysco leaves the contours of “sufficient particularity” deliberately under-specified. The panel condemned definitions that swallow an entire business, but it did not chart how granular a plaintiff must be when its secret is genuinely a compilation or a combination of otherwise-known elements—a recurring problem in manufacturing and software cases. Nor did the court address the timing question that divides the circuits with full force: whether particularity is owed at the pleading stage in all events, or whether some refinement may await discovery. The Fourth Circuit’s answer here was emphatically pleading-stage, but the opinion’s reasoning—that identification is the gate to the substantive elements—does not by itself resolve cases where the misappropriated detail is in the defendant’s exclusive possession. Finally, the court’s treatment of copyright-registered drawings as categorically disclosed invites questions at the margins, including how redaction practices and the Copyright Office’s own deposit rules interact with claims that surrounding know-how remains secret.

Implications

  • Plead one secret well, not everything broadly. A complaint that defines the secret expansively to preserve optionality now reads, in the Fourth Circuit, as a complaint that has identified nothing and is implausible on its face.
  • Audit the public record before filing. Materials deposited with the Copyright Office, disclosed in patents, or otherwise public will not just fail—they affirmatively undercut the credibility of the broader claim.
  • Allege the duty. Particularity gets a plaintiff to the door; misappropriation requires a pleaded breach of a confidentiality or trust obligation. Lawful acquisition by a distributor or counterparty defeats the claim regardless of how well the secret is described.
  • Mind the litigation history. The panel’s affirmance of the denial of leave to amend reflects judicial impatience with serial, materially identical filings; repeated bites at the apple can foreclose amendment.
  • The circuit divide is live. Practitioners should expect forum-dependent outcomes: the Ninth Circuit’s more discovery-tolerant line (InteliClear, Quintara) and the Fourth Circuit’s pleading-stage rigor now sit on opposite ends of the same question.

Frequently asked questions

Does Sysco require a plaintiff to disclose its trade secret publicly to plead a claim? No. The court distinguishes between identifying a secret with enough particularity to give notice and assess plausibility, and revealing its protected substance to the world. A plaintiff can describe the contours and category of the asserted information specifically without publishing the secret itself; what it cannot do is substitute sweeping labels for identification.

Why did information registered with the Copyright Office defeat the trade-secret claim? Because trade-secret protection depends on secrecy, and the panel held that depositing the technical drawings, unredacted, with the Copyright Office extinguished their secret status. Once information is in the public record, it no longer derives independent economic value from not being generally known.

Is the Fourth Circuit now stricter than other circuits on trade-secret pleading? It is at the more demanding end. Sysco insists on particularity at the pleading stage and ties it directly to Twombly/Iqbal plausibility, whereas several courts—most visibly the Ninth Circuit—allow identification to be refined through discovery. The result is a recognized split that makes forum and pleading strategy consequential.
