Trade Secret Litigation: Stopping Misuse and Defending Against Claims
When a customer list, pricing model, formula or source code walks out the door, the first two weeks decide most of what follows. Experienced counsel knows what a Texas or federal court will enjoin, what it will not, and how to protect the secret while litigating over it.

The situations that bring companies here
Trade secret matters start fast and on both sides of the table.
- 01An employee left with your customer listDownloads the week before resignation, a personal email forward, a competitor's outreach to your accounts. Whether the list is a trade secret depends on how it was built and protected.
- 02You want to stop a former employee before the damage is doneTexas law allows an injunction against threatened misappropriation, not only completed misuse, but the evidence has to show the threat rather than the fear.
- 03Your new hire is accused of bringing a competitor's secretsThe letter arrives days after the start date and names the company as well as the person. The response has to protect the business without conceding the claim.
- 04A vendor or partner used what the NDA protectedInformation shared for one project shows up in a competing bid or product. Contract and trade secret claims run together, with different proof and different remedies.
- 05You need an emergency order this weekA temporary restraining order, expedited discovery and a protective order can be in place within days when the evidence is organized and the request is proportionate.
- 06You want to inspect a departing employee's devices and accountsCompany-owned systems can be imaged and reviewed; personal devices and accounts cannot be searched without consent or a court order. Getting this wrong hands the other side a claim.
How a trade secret matter is handled
Definition, preservation, forum, speed. In that order.
Define the secret precisely
A court will not protect 'our confidential information'. The claim names the specific list, formula, code or process, shows the reasonable measures taken to keep it secret and explains why it has value because it is not generally known.
Preserve the evidence, lawfully
A forensic image of company devices and accounts, access and download logs, badge records and a litigation hold go in place at once. Searches of personal accounts or devices wait for consent or a court order.
Choose the forum and the statutes
Texas state court under the Texas Uniform Trade Secrets Act, federal court under the Defend Trade Secrets Act, or both statutes pleaded together, plus contract claims under the NDA or employment agreement. The parties, the evidence and the calendar decide.
Move for emergency relief when the facts support it
A temporary restraining order, expedited discovery, return or sequestration of the material and a protective order that keeps the secret out of the public file. The request is scoped to what the evidence shows so that it holds at the hearing.
Measure damages and the realistic end game
Actual loss, the other side's unjust enrichment or a reasonable royalty, the chance of exemplary damages and fees, and the cost of getting there. Many matters resolve on an injunction by agreement, certified destruction and a payment.
Defend the accused company with the same discipline
For a company or a new hire accused of misappropriation: isolate the material, document what was and was not used, respond on the merits and press for fees where the claim was brought in bad faith.
The Texas and federal law that applies
The Texas Uniform Trade Secrets Act: Civil Practice and Remedies Code chapter 134A
Texas protects all forms and types of information, including a formula, design, program, method, process, financial data or a list of actual or potential customers or suppliers, if the owner has taken reasonable measures under the circumstances to keep it secret and it derives independent economic value from not being generally known or readily ascertainable by proper means (Tex. Civ. Prac. & Rem. Code § 134A.002(6)). Misappropriation is acquiring the information by improper means (theft, bribery, misrepresentation, breach of a duty of secrecy, espionage) or using or disclosing it in breach of such a duty or with reason to know it came that way (§ 134A.002(2), (3)). Reverse engineering of a lawfully acquired product and independent development are proper means.
A court may enjoin actual or threatened misappropriation, but the order may not stop a person from using the general knowledge, skill and experience acquired during employment (§ 134A.003(a)). In exceptional circumstances the court may allow future use on payment of a reasonable royalty (§ 134A.003(b)). Damages are the owner's actual loss plus the unjust enrichment not already counted, or a reasonable royalty; where willful and malicious misappropriation is proved by clear and convincing evidence, exemplary damages of up to twice that amount may be awarded (§ 134A.004). Attorney's fees go to the prevailing party when a claim is made in bad faith, a motion to terminate an injunction is made or resisted in bad faith, or the misappropriation was willful and malicious (§ 134A.005). The court must preserve the secrecy of the alleged trade secret, with a presumption in favor of protective orders, sealed records and attorney-only access where the balancing factors in § 134A.006(b) support it. The act displaces other Texas tort theories for the same misappropriation but leaves contract claims, such as a breached NDA, untouched (§ 134A.007). Suit must be filed within three years after the misappropriation was or should have been discovered (§ 16.010).
The federal Defend Trade Secrets Act: 18 U.S.C. § 1836
An owner may also sue in federal court when the trade secret relates to a product or service used in interstate or foreign commerce (§ 1836(b)(1), (c)). The remedies track Texas law: an injunction, actual loss and unjust enrichment or a reasonable royalty, exemplary damages up to two times for willful and malicious misappropriation, and fees for bad faith or willfulness (§ 1836(b)(3)). The federal statute adds an ex parte seizure order, available only in extraordinary circumstances (§ 1836(b)(2)), and it states that an injunction may not prevent a person from entering into an employment relationship and that any conditions on employment must rest on evidence of threatened misappropriation, not merely on the information the person knows (§ 1836(b)(3)(A)(i)). The limitations period is also three years from discovery (§ 1836(d)). Most Texas complaints plead both statutes; where the case is filed depends on the parties, the evidence already in hand and the court's calendar.
Why experience in trade secret cases changes the outcome
Trade secret cases are decided early and on detail. The definition of the secret in the first pleading, the scope of the restraining order requested, the forensic steps taken in the first 72 hours and the protective order negotiated before discovery each shape what the court will grant months later. An overbroad request loses credibility at the temporary injunction hearing; a narrow, documented one is granted and holds.
Tina Wysk represents trade secret owners and accused companies in Dallas state and federal courts and in arbitration, and her employer-side practice covers the related non-compete, non-solicitation and departing-employee disputes that usually travel with a trade secret claim. Having argued both sides of these motions shapes the advice: when a TRO is worth seeking and when a demand with a preservation notice does more, how to keep the secret sealed while proving it, and how to end the matter with an enforceable agreement rather than an injunction that still has to be policed.

The business cost of a dispute
What a trade secret dispute costs the business
These costs run while the matter is open, on both sides.
The secret itself
Once a formula, price list or customer file is in general circulation, no injunction brings it back. Damages compensate; they do not restore the advantage. Speed at the start protects what a judgment later cannot.
Customers in play
While the dispute runs, the accounts named in the complaint are being called by both sides. Sales leadership spends the quarter defending relationships instead of building them.
A public record
Pleadings are public unless the court seals them. Texas law presumes in favor of protective orders in trade secret cases, but the protection has to be requested and shaped, or the lawsuit itself discloses what it was filed to protect.
Hiring and onboarding under a cloud
For the accused company, a new hire under a restraining order cannot do the job he or she was hired for, forensic reviews of devices cost money and time, and recruiting slows while the matter is unresolved.
Weeks of expedited attention
Emergency motions compress months of litigation into weeks. Executives give declarations and depositions on short notice and IT staff produce logs instead of running systems. The schedule is set by the court, not the business.
Questions
Questions about trade secret disputes in Texas
What counts as a trade secret under Texas law?
Any form of business, technical or financial information, including a customer or supplier list, if the owner took reasonable measures under the circumstances to keep it secret and it has independent economic value because it is not generally known or readily ascertainable by proper means (Texas Civil Practice and Remedies Code section 134A.002). The definition is broad, but both conditions must be met. Information that was never protected, or that a competitor could assemble from public sources, usually fails the test.
Can I stop a former employee before they actually use my trade secrets?
Texas law allows a court to enjoin threatened misappropriation, not only completed misuse (section 134A.003). The evidence has to show a real threat, such as downloads before departure, retained files or a role at the competitor that cannot be performed without the information. Neither Texas nor federal law allows an order that stops a person from using general knowledge, skill and experience, and the federal statute adds that an injunction may not prevent someone from taking a job.
How quickly can a court act?
A temporary restraining order can be obtained within days when the evidence is organized and the request is specific, and it is short-lived by design, followed by a temporary injunction hearing where both sides present evidence. Expedited discovery and a protective order usually accompany the first motion. The speed depends on how quickly the company can show what the secret is, how it was protected and what the other side did with it.
Should the case be filed in state court or federal court?
Either can work. The Texas Uniform Trade Secrets Act applies in state court; the federal Defend Trade Secrets Act gives federal jurisdiction when the secret relates to a product or service in interstate commerce, and Texas claims can be joined to it. The remedies are nearly identical, so the choice turns on the parties' locations, the judge's calendar, the availability of an ex parte seizure order under federal law and where the evidence and witnesses are.
Can I recover attorney's fees in a trade secret case?
Only in defined situations. Under both Texas and federal law, fees may be awarded to the prevailing party when a misappropriation claim was made in bad faith, when a motion to terminate an injunction was made or resisted in bad faith, or when the misappropriation was willful and malicious (section 134A.005; 18 U.S.C. section 1836(b)(3)(D)). Fees are not automatic for winning. A well-drafted NDA or employment agreement may add a contractual fee clause.
My company has been accused of trade secret misappropriation. What should we do first?
Preserve everything, stop any use of the material in question and document that step. Do not delete files or wipe devices, which turns a defensible case into a spoliation problem. Then examine the claim: whether the information meets the legal definition, whether the measures to protect it were reasonable, and what the accused person actually brought and used. Where the claim was made in bad faith, the statute allows a fee award against the claimant.
How long do I have to sue for trade secret misappropriation?
Three years from the date the misappropriation was discovered or, with reasonable diligence, should have been discovered, under both Texas law (Texas Civil Practice and Remedies Code section 16.010) and the federal act (18 U.S.C. section 1836(d)). A continuing misappropriation is a single claim; the clock does not restart with each new use. Related contract claims under an NDA follow their own limitations period.

Usually not. Texas names customer lists as possible trade secrets, but only if you kept the list secret and it has value competitors cannot easily rebuild.

Can I Stop a Former Employee Before They Actually Use My Trade Secrets?
Yes, with evidence of a real threat. Texas and federal law allow injunctions against threatened misappropriation, but not merely because the employee knows your secrets.
