Damages in Trade Secret Cases: Lost Profits, Unjust Enrichment and Royalties

The three measures, and how they fit together

Section 134A.004(a) of the Texas Civil Practice and Remedies Code sets out the damages available for misappropriation. The owner may recover the actual loss caused by the misappropriation and, in addition, the unjust enrichment caused by it that is not taken into account in computing actual loss. If neither can be proved by other methods, the damages may instead be measured by a reasonable royalty for the unauthorized disclosure or use. The federal Defend Trade Secrets Act, 18 U.S.C. § 1836(b)(3)(B), uses the same three measures in nearly the same words.

The structure matters. Actual loss and unjust enrichment can be combined, but only to the extent they do not double count the same dollars. The reasonable royalty is an alternative, not an add-on, used when the first two cannot be proved. Which path the owner takes is often the central strategic decision in the damages case, and it is driven by what the evidence shows.

Damages are available in addition to or in lieu of an injunction. An owner can obtain an order stopping future use and recover for the use that already occurred. The emergency stage is covered separately in getting an emergency injunction to stop trade secret misuse.

Actual loss: what the owner lost

Actual loss measures the owner's own harm. The most common components are:

• Lost profits on sales the owner would have made but for the misappropriation, usually shown through lost customers, lost bids or a decline in sales traced to the defendant's entry.
• Price erosion, where the owner kept the customer but had to cut its price to compete with a rival using the owner's own cost data.
• Lost value of the secret, where disclosure destroyed the secret entirely and the owner can show what the information was worth as an asset.
• Remediation costs, such as the expense of investigating the taking and re-securing systems, to the extent they were caused by the misappropriation.

Lost profits must be proved with reasonable certainty. Texas courts do not require mathematical exactness, but they require a basis in objective facts and figures, not a projection built on the owner's optimism. Historic sales, margins, customer-level data and the timing of the defendant's competitive activity are the raw material. Where the owner is a start-up with no sales history, actual loss is hard to prove and the inquiry usually shifts to the defendant's side of the ledger.

Unjust enrichment: what the defendant gained

Unjust enrichment measures the benefit the misappropriation conferred on the defendant. It is especially useful where the defendant profited but the owner's own sales did not visibly fall, for example because the defendant sold into markets the owner had not yet reached. Common forms include:

• The defendant's profits on products or sales attributable to the trade secret, net of the costs properly chargeable to them.
• Development costs saved, sometimes called the head start: what the defendant would have had to spend, and how long it would have taken, to develop the information independently.
• Increased value of the defendant's business, in cases where the misappropriation was the foundation of an acquisition or investment.

The statute's words, not taken into account in computing actual loss, are the guard against double recovery. If the owner recovers lost profits on a sale the defendant made, it cannot also recover the defendant's profit on the same sale. Where the two measures reach different dollars, both can be awarded.

Reasonable royalty: the fallback

When the owner cannot prove its loss and cannot prove the defendant's gain, the statute allows a reasonable royalty. The concept is a hypothetical negotiation: what a willing licensor and a willing licensee would have agreed as the price for the use the defendant actually made, at the time the misappropriation began. Evidence includes the owner's actual licenses of comparable information, industry royalty rates, the defendant's expected profits from the use, and the cost of the alternatives available to the defendant.

A royalty is often the realistic measure in cases where the defendant used the secret to compete but has not yet made much money, or where the owner's lost sales cannot be separated from other market forces. It is also the form a court may choose for a continuing remedy: section 134A.003(b) allows a court, in exceptional circumstances, to condition future use on payment of a reasonable royalty instead of prohibiting use outright.

Example

Suppose a Dallas industrial coatings company proves at trial that a former chemist took its formulation for a corrosion-resistant primer to a competitor, which launched a matching product. The owner shows that it lost three accounts to the competitor's product, with lost profits on those accounts of $410,000 through trial. The competitor's own records show it earned $260,000 in profit on sales of the matching product, of which $150,000 came from the same three accounts and $110,000 from customers the owner never served. The competitor also saved roughly two years of laboratory work, which its own development budget put in the hundreds of thousands of dollars.

The owner may recover its $410,000 actual loss. It may add unjust enrichment that the loss figure did not capture: the $110,000 in profit from other customers, and a head-start figure if the jury accepts it, but not the $150,000 in profit on the three accounts already counted in the lost-profits award. If the jury also finds willful and malicious misappropriation by clear and convincing evidence, exemplary damages of up to twice the total compensatory award are available. These figures are illustrative only; every case turns on its own records.

Exemplary damages: the two-times cap

Section 134A.004(b) allows exemplary damages when willful and malicious misappropriation is proved by clear and convincing evidence, in an amount not to exceed twice the damages awarded under subsection (a). The Texas Act defines willful and malicious misappropriation in section 134A.002(7) as intentional misappropriation resulting from the conscious disregard of the rights of the owner. The federal Act uses the same cap for willful and malicious misappropriation.

The standard is demanding. An employee who took files carelessly, or a company that used information it genuinely believed was its own, is not within it. An employee who downloaded the files the night before resigning, lied about it when asked and used them at the competitor the next week usually is. The evidence that proves the taking, especially the timeline and the attempts to cover it, is the same evidence that proves malice.

Attorney's fees

Texas follows the American rule, so fees are not automatic. Section 134A.005 permits the court to award reasonable attorney's fees to the prevailing party in three situations: a claim made in bad faith, a motion to terminate an injunction made or resisted in bad faith, and willful and malicious misappropriation. The federal Act matches. A confidentiality agreement with its own fee clause, or a breach of contract claim under chapter 38 of the Civil Practice and Remedies Code, can supply fees that the trade secret statute alone would not. The details are in fee awards in trade secret and trademark cases.

How damages are proved

Three sources of proof carry most trade secret damages cases.

1. The owner's financial records: customer-level sales and margin history before and after the misappropriation, bid logs, pricing files and development budgets.
2. The defendant's records, obtained in discovery: sales of the accused product or to the disputed customers, cost data, internal communications about the information's value, and the development timeline. These are produced under the protective order that section 134A.006 presumes should be granted.
3. Expert testimony: a forensic accountant or damages economist who ties the records to a method the jury can follow, and a technical expert who establishes that the defendant's product or process actually used the secret. The standards for admitting such testimony are covered in when a business case needs an expert witness.

The weakest link is usually causation: showing that the lost sale or the defendant's profit flowed from the trade secret rather than from price, relationships or ordinary competition. Defense experts attack that link first, and the owner's damages model has to anticipate it.

Timing and the three-year deadline

The claim must be brought within three years of the date the misappropriation was or should have been discovered under section 16.010 of the Civil Practice and Remedies Code. Damages continue to accrue through trial, and a continuing misappropriation is treated as a single claim, so the owner recovers for the whole period of use once the suit is timely. Owners who waited to file while losses mounted are not barred, but the delay is often used against them on causation and on the imminence needed for an injunction. The statute as a whole is described in the Texas Uniform Trade Secrets Act, explained.

What this means for the owner's decision

Damages in a trade secret case are rarely obvious at the start. The injunction stops the harm; the damages case decides whether the lawsuit pays for itself. The questions a litigator asks early are whether the owner's records can show a loss, whether the defendant is likely to have gains worth pursuing, whether the facts support a willful and malicious finding, and whether a royalty theory is a better fit than either.
