Trade-Secret Unjust Enrichment Can Be Inferred from Trial Testimony; Delay and “No Loss” Jury Finding Defeat Permanent Injunction

1. Introduction

The Hurry Family Revocable Trust, Scottsdale Capital Advisors Corporation, and Alpine Securities Corporation (collectively, “Alpine”) sued former Alpine CEO Christopher Frankel after he allegedly forwarded “hundreds of pages” of Alpine’s confidential documents to his personal email and used that information to compete, including through his subsequent employment at Vision Financial Markets, LLC (“Vision”).

Alpine asserted (i) breach of nondisclosure agreements, (ii) trade secret misappropriation under the federal Defend Trade Secrets Act (18 U.S.C. § 1836(b)) and the Florida Uniform Trade Secrets Act (Fla. Stat. ch. 688), and sought remedies including unjust enrichment and injunctive relief.

The appeal presented three principal issues: (1) whether the district court abused its discretion by excluding a late defense witness (John Fife) at trial; (2) whether Alpine was improperly permitted to argue and illustrate unjust enrichment despite earlier discovery disputes over damages computation; (3) whether sufficient evidence supported a $932,000 unjust enrichment verdict; plus Alpine’s cross-appeal challenging the denial of a permanent injunction.

2. Summary of the Opinion

The Eleventh Circuit affirmed across the board. It held that:

  • The district court acted within its broad trial-management discretion in excluding Fife because Frankel raised the witness at the tail end of trial and Fife was not on the pretrial “real” witness list exchanged shortly before trial.
  • Alpine did not “ambush” Frankel with unjust enrichment: it pled and disclosed the theory early, and the closing demonstrative was properly grounded in trial testimony (helping the jury “follow the math”).
  • The evidence permitted a reasonable jury to infer unjust enrichment from misappropriation (customer list/revenue information), and the $932,000 figure had reasonable evidentiary anchors given the flexible unjust enrichment standard for trade secret cases.
  • The district court did not abuse its discretion in denying a permanent injunction because Alpine failed to establish irreparable harm and the inadequacy of legal remedies—particularly in light of Alpine’s delay in seeking injunctive relief and the jury’s finding of no monetary harm (even nominal).

3. Analysis

3.1. Precedents Cited

A. Standards of review and deference to trial courts

  • McGinnis v. Am. Home Mortg. Servicing, Inc.: Used to frame abuse-of-discretion review for denial of a new trial and to emphasize heightened deference where the jury’s verdict remains intact.
  • Chrysler Int'l Corp. v. Chemaly, Perez v. Miami-Dade County, and United States v. Hilliard: Cited for the proposition that district courts must have “broad discretion” to manage cases, discovery, scheduling, and trials.
  • Chudasama v. Mazda Motor Corp.: Supplies the important limiting principle: discretion is broad but not “unfettered,” reinforcing that appellate review looks for “clear error of judgment” or “misapplication of law.”
  • Henderson v. Ford Motor Co.: Used repeatedly as the articulation of when trial-management rulings should be disturbed—only for clear error of judgment or legal misapplication—and to locate the “range of choices” concept in evidentiary and trial-control rulings.
  • Circuitronix, LLC v. Kinwong Elec. (Hong Kong) Co., Ltd.: Appears in Frankel’s attempt to obtain de novo review by characterizing the witness exclusion as a Rule 26 legal interpretation. The court distinguished it, concluding the ruling primarily reflected trial-management discretion.

B. Excluding witnesses and enforcing pretrial understandings

  • Com. Union Ins. Co. v. M/V Bill Andrews: Provided an analogy supporting exclusion of a witness where pretrial handling effectively signaled the witness would not be deposed or called; it supports the legitimacy of enforcing pretrial expectations to prevent prejudice and disruption.
  • Fabrica Italiana Lavorazione Materie Organiche, S.A.S. v. Kaiser Aluminum & Chem. Corp.: Invoked to underscore that, in context, the district court’s balancing of prejudice and timing is a reasonable trial-management call.
  • Bonner v. City of Prichard: Included to explain that pre-October 1981 Fifth Circuit decisions remain binding in the Eleventh Circuit—important because several key trade secret principles derive from former Fifth Circuit authority.

C. Judgment as a matter of law and evidentiary sufficiency

  • Doe v. Celebrity Cruises, Inc.: Supplies de novo review and the requirement to view evidence in the light most favorable to the non-movant.
  • Lipphardt v. Durango Steakhouse of Brandon, Inc.: Provides the “no legally sufficient evidentiary basis” formulation for Rule 50 relief.
  • Crawford v. ITW Food Equip. Grp., LLC: Reinforces that all evidence and inferences are drawn in favor of the prevailing party on sufficiency review.

D. Trade secret unjust enrichment: flexible valuation and approximation

  • Univ. Computing Co. v. Lykes-Youngstown Corp.: The centerpiece for unjust enrichment in trade secret cases: the measure is the “value of the secret to the defendant,” the inquiry is “very flexible,” and the remedy can strip “benefits, profits, or advantages” gained from use of the secret—even absent proof of the plaintiff’s specific injury.
  • Syntel Sterling Best Shores Mauritius Ltd. v. The TriZetto Grp., Inc.: Cited as a comparative reference (Second Circuit) consistent with flexible unjust enrichment methodologies in trade secret cases.
  • Premier Lab Supply, Inc. v. Chemplex Indus., Inc.: Supplies Florida-law support that only a “reasonable basis” is needed to infer or approximate unjust enrichment amounts.
  • Perdue Farms Inc. v. Hook: Used to reinforce that trade secret damages are not a “perfect science” and to legitimize reasonable alternative methods of arriving at a figure.
  • United States v. Killough: Cited for the general principle that damages need not be calculated with “mathematical precision.”
  • Fin. Info. Techs., LLC v. iControl Sys., USA, LLC: Important procedural point: with a general verdict, Alpine needed to show misappropriation of at least one trade secret to sustain the verdict.

E. Permanent injunction standards and the effect of delay and jury findings

  • Common Cause/Georgia v. Billups: Sets review structure: abuse of discretion overall, clear error for factual findings, de novo for legal conclusions.
  • KH Outdoor, LLC v. City of Trussville: Confirms success on the merits is a predicate for permanent injunctive relief.
  • eBay Inc. v. MercExchange, L.L.C.: Establishes the four-factor permanent injunction test (irreparable harm, inadequacy of legal remedies, balance of hardships, public interest).
  • Ferrero v. Associated Materials Inc.: Supports that loss of customers can constitute irreparable harm—yet the court held Alpine still failed on this factor given its litigation conduct.
  • Wreal, LLC v. Amazon.com, Inc.: Supplies the key theme that delay can “militate against a finding of irreparable harm” because preliminary relief is intended to protect rights before merits resolution.
  • Y.Y.G.M. SA v. Redbubble, Inc.: Ninth Circuit authority relied upon for the proposition that delay in seeking preliminary relief can undermine permanent injunctive relief as well.
  • Dybczak v. Tuskegee Inst. and BUC Int'l Corp. v. Int'l Yacht Council Ltd.: Used for the principle that jury findings necessarily made on legal claims bind the court when resolving equitable claims—crucial to the “no adequate remedy” analysis because the jury found no monetary harm (not even nominal).

3.2. Legal Reasoning

A. Witness exclusion as trial management (not a technical Rule 26 trap)

The court treated the Fife issue primarily as a timing and fairness problem. Frankel waited until the fourth day of a five-day trial to announce he wanted to call Fife “the next day,” after Alpine had already presented its case and after Alpine’s questioning had made the Fife Entities’ role apparent by day two. Compounding the issue, Fife was not on the pretrial “real” witness list Frankel exchanged shortly before trial, a fact that drove Alpine’s surprise and the court’s concern about prejudice and disruption.

The Eleventh Circuit’s emphasis is practical: even if earlier documents had once listed Fife as a possible witness, the operative trial expectations were set by the later “real list” and by Frankel’s conduct as the trial unfolded. The court framed exclusion as a legitimate enforcement of orderly trial procedure and avoidance of “massive prejudice.”

B. Unjust enrichment theory was not a “trial ambush”

The panel rejected the premise that Alpine surprised Frankel with unjust enrichment. Alpine pled unjust enrichment in the complaint, referenced it in initial disclosures, and repeatedly sought discovery aimed at commissions/profits tied to former Alpine clients. The panel also credited Alpine’s consistent representation that it could not compute a number earlier because the underlying information was controlled by Frankel and/or third parties.

On the closing demonstrative, the court drew a line between (i) presenting a wholly new damages model and (ii) using admitted testimony to show the jury the arithmetic of inferences it may draw. The demonstrative fell into the latter category: it was “math based on [Frankel’s] testimony” to help the jury “follow the math.” This approach aligns with the court’s earlier ruling limiting Alpine from presenting undisclosed damage computations while still allowing examination about commissions/bonuses from clients who moved to Vision.

Notably, although not dispositive to its holding, the opinion’s footnote flags how Federal Rule of Civil Procedure 37’s “substantially justified or harmless” safety valve can support a trial court’s decision to allow use of numbers that only crystallize through trial testimony, especially where the opponent held the data “all along” yet did not disclose it.

C. Sufficiency of evidence for $932,000 unjust enrichment under DTSA/FUTSA

The court anchored its analysis in Univ. Computing Co. v. Lykes-Youngstown Corp.: unjust enrichment in trade secret cases measures “the value of the secret to the defendant,” is “very flexible,” and does not require plaintiff proof of specific loss. With a general verdict, Alpine needed to show misappropriation of at least one trade secret; the customer list and revenue information sufficed.

The linkage between use and gain was inferential but permissible: Frankel possessed Alpine’s client list/revenue data, communicated with Chicago Venture about better rates relative to Alpine, highlighted the importance of landing that business, and testified that commissions from the Fife Entities flowed into the profit bucket from which he received a share. The jury could reasonably infer he gained an advantage from the information.

On the number, the court approved approximation based on trial evidence, describing two rational pathways:

  1. Using Frankel’s approximate six-month profit share ($264,000) and extrapolating over the period between his Vision start and trial;
  2. Using the “at least” $100,000/month commissions from the Fife Entities and applying margins referenced at trial to approximate net revenue.

The key move is methodological tolerance: the jury is not required to reach mathematical certainty; it needs only a reasonable evidentiary basis to infer or approximate the value captured by the defendant.

D. Permanent injunction denied: delay + jury’s “no harm” finding

Although Alpine succeeded on the merits (liability), it failed to establish irreparable injury and inadequacy of legal remedies under eBay Inc. v. MercExchange, L.L.C.. The district court’s skepticism—affirmed on appeal—turned heavily on Alpine’s delay: despite early knowledge of alleged misappropriation, Alpine did not pursue preliminary relief and sought a permanent injunction only after the verdict. Citing Wreal, LLC v. Amazon.com, Inc. and Y.Y.G.M. SA v. Redbubble, Inc., the panel accepted delay as probative evidence against claimed irreparability.

On legal adequacy, the jury was instructed it could award nominal damages if harm existed but was unquantifiable; it awarded none and affirmatively found no monetary harm. Through Dybczak v. Tuskegee Inst. and BUC Int'l Corp. v. Int'l Yacht Council Ltd., that factual finding constrained equitable relief: the court treated it as binding for the equitable-remedy analysis. Alpine’s argument that unjust enrichment implied harm failed because unjust enrichment is about the defendant’s gain, not the plaintiff’s loss (again returning to Univ. Computing Co. v. Lykes-Youngstown Corp.).

3.3. Impact

  • Trial practice and witness control: The decision signals that “real” witness lists and the timing of witness announcements carry real weight. Even where a witness appeared on earlier, broader lists, late-stage trial additions—especially after the opposing party has rested—are vulnerable to exclusion as a matter of docket control and prejudice avoidance.
  • Damages disclosure vs. trial proof: While Rule 26 expects a “computation,” the opinion implicitly accepts that a court may permit closing arithmetic derived directly from trial testimony even when a pretrial computation was barred—particularly where the relevant numbers were in the opponent’s possession and emerge only under cross-examination.
  • Trade secret unjust enrichment: The case reinforces a defendant-value framework for unjust enrichment and the permissibility of approximation. Plaintiffs may sustain awards without proving traditional “actual damages,” so long as evidence supports an inference of benefit derived from misappropriation.
  • Injunction strategy: Delay in seeking preliminary relief can materially weaken a later claim of irreparable harm—even when liability is proven. The opinion is also a cautionary note that jury findings on monetary harm (including rejection of nominal damages) may bind and narrow a court’s equitable remedial discretion.

Note: The opinion is marked “NOT FOR PUBLICATION,” so it is not precedential in the same way as published circuit authority, but it is informative as to how the Eleventh Circuit applies established standards to common trade secret litigation dynamics.

4. Complex Concepts Simplified

  • Unjust enrichment (trade secrets): Not “what the plaintiff lost,” but “what the defendant gained” from using the secret—often framed as the secret’s value to the defendant. It can be awarded even if the plaintiff cannot prove lost profits.
  • General verdict: A verdict that does not specify which exact trade secret(s) drove liability; on appeal, the verdict stands if the record supports misappropriation of at least one trade secret.
  • Rule 50 judgment as a matter of law: A post-trial mechanism to overturn a jury verdict only when no reasonable jury could have reached it, viewing evidence in favor of the verdict winner.
  • Permanent injunction factors (eBay test): Even after winning at trial, a party must prove irreparable harm and that money damages are inadequate, among other factors. Winning liability does not automatically entitle the plaintiff to an injunction.
  • Delay and irreparable harm: Courts infer that if harm were truly irreparable and urgent, the plaintiff would have sought preliminary relief promptly.

5. Conclusion

The Hurry Family Revocable Trust v. Christopher Frankel affirms three practical principles in trade secret litigation: (1) district courts have wide latitude to exclude late-disclosed or late-announced witnesses to preserve fair and orderly trials; (2) unjust enrichment may be argued and quantified through reasonable inferences and arithmetic grounded in trial testimony, consistent with the flexible “value to the defendant” framework; and (3) permanent injunctive relief remains an equitable, factor-driven remedy—often defeated by strategic delay and by jury findings that undermine claims of irreparable harm or inadequate legal remedies.
