The Defend Trade Secrets Act is a 2016 federal law that gives trade secret owners the right to sue in federal court when their confidential business information is stolen or misused. Signed on May 11, 2016, it amended the Economic Espionage Act to create the first federal civil cause of action for trade secret misappropriation, so long as the trade secret relates to interstate or foreign commerce. It offers injunctions, compensatory and exemplary damages, attorney fees in willful cases, and an unusual power to have federal officers seize stolen materials before the defendant even knows a lawsuit exists. Claims must be filed within three years of discovery.
What Qualifies as a Trade Secret
Under 18 U.S.C. § 1839(3), information is a trade secret when two things are true: the owner took reasonable steps to keep it secret, and the information gets its economic value specifically from not being publicly known or easily figured out by competitors. The category is broad. Financial data, scientific research, engineering processes, software code, formulas, and business strategies can all qualify. What matters is not the label but whether secrecy is what makes the information valuable.
The “reasonable measures” requirement is where many claims succeed or fail. Courts look at what the owner actually did. Confidentiality agreements with employees and vendors, password protection and physical access controls, and limiting the number of people who see the full picture all count. A company that shares its supposedly secret formula openly at an industry conference, or leaves it on an unsecured server, has a hard time arguing it took reasonable precautions. The bar is not perfection. It is a pattern of genuine effort.
The economic value element asks whether a competitor would gain an advantage from knowing the information. A customer list with negotiated pricing terms that took years to build has independent value because a rival could use it to undercut deals. A manufacturing process that cuts production costs by 30% clearly qualifies. The value has to come from the secrecy itself, not just from the information being generally useful.
What Counts as Misappropriation
Misappropriation under 18 U.S.C. § 1839(5) takes two forms. The first is acquiring a trade secret when you know, or should know, it was obtained through improper means. The second is disclosing or using a trade secret without consent when you acquired it improperly, learned it from someone who did, or received it under circumstances that created a duty to keep it confidential.
“Improper means” under § 1839(6) covers theft, bribery, misrepresentation, hacking, and inducing someone to break a confidentiality obligation. An employee who downloads a proprietary database before jumping to a competitor, or a consultant who shares a client’s process specifications with a rival, both fall within the definition. The wrongful acquisition alone is enough. The defendant does not have to have profited from the secret for liability to attach.
Two things are not misappropriation. Reverse engineering a publicly available product is lawful. So is independently developing the same information through your own research. If a competitor buys your product off the shelf, takes it apart, and figures out how it works, the DTSA gives you no remedy. That is why trade secret protection is narrower than patent protection: it does not stop anyone from reaching the same result through legitimate effort.
Getting Into Federal Court
To sue under the DTSA, the trade secret must relate to a product or service used in, or intended for use in, interstate or foreign commerce. That requirement, in 18 U.S.C. § 1836(b)(1), is what establishes federal jurisdiction. A software company selling across state lines, a manufacturer exporting components, or a pharmaceutical firm developing drugs for national distribution all satisfy it easily. A purely local operation with no interstate connection would not, though in practice most businesses touch interstate commerce in some way.
Filing federally does not force a choice between federal and state law. The Act contains no preemption provision, so plaintiffs can pursue DTSA claims and state trade secret claims in the same lawsuit. Nearly every state has adopted some version of the Uniform Trade Secrets Act, and running parallel claims can be strategic: a state law might offer a longer limitations period or a different remedy in a particular situation.
Remedies Available
The DTSA gives courts several categories of relief under 18 U.S.C. § 1836(b)(3), and they can be combined depending on the facts.
Injunctions
A court can order a defendant to stop ongoing or threatened misappropriation. That might mean stopping the manufacture of a product that uses the trade secret, returning stolen documents, or ending the use of proprietary data. When an injunction is not practical because the secret has spread too widely, the court can instead impose a reasonable royalty on the defendant’s continued use.
One limit on injunctions catches employers by surprise. Under § 1836(b)(3)(A)(i)(I), a court cannot use a DTSA injunction to keep someone from taking a new job. Any conditions on future employment must rest on evidence of threatened misappropriation, not simply on the fact that the person knows confidential information. Congress wrote this to reject the “inevitable disclosure” theory that some state courts had used to block employees from working for competitors. The injunction also cannot conflict with state laws that prohibit restraints on practicing a lawful profession or trade.
Damages
A plaintiff can recover compensatory damages for actual losses caused by the misappropriation, plus any unjust enrichment the defendant gained that is not already reflected in the loss figure. If a former employee used stolen customer data to divert $2 million in business, the plaintiff could recover that lost revenue and any additional profit the defendant earned from those diverted customers.
When the misappropriation was willful and malicious, the court can add exemplary damages of up to twice the compensatory amount, plus reasonable attorney fees. A $500,000 compensatory award can become $1.5 million once exemplary damages and legal costs are added. Courts reserve this enhanced recovery for deliberate, bad-faith conduct rather than negligence or honest disputes about what information was protected.
Ex Parte Seizure Orders
The most aggressive tool in the DTSA is the ex parte seizure provision at 18 U.S.C. § 1836(b)(2). It lets a court order federal law enforcement officers to physically seize property, such as laptops, hard drives, documents, or prototypes, without giving the defendant advance notice. A federal officer carries out the seizure. State or local officials can assist, but the applicant and the applicant’s agents cannot participate.
Because the remedy is so invasive, it is available only in extraordinary circumstances. The applicant has to show, through specific facts in a sworn affidavit or verified complaint, that:
- an injunction or other standard remedy would be inadequate to protect the trade secret;
- the defendant would likely destroy, move, or hide the evidence if given notice through normal channels;
- the application describes the property to be seized and its location with enough particularity that officers can act.
The applicant must also post security in an amount the court considers adequate to cover damages if the seizure turns out to be wrongful or excessive. A hearing must take place no later than seven days after the seizure, giving the defendant a chance to challenge the order. The defendant can also move to dissolve or modify the seizure at any time on notice to the applicant. These safeguards exist because an unjustified seizure can cripple a business overnight.
The Three-Year Deadline
A civil DTSA claim has to be filed within three years. Under 18 U.S.C. § 1836(d), the clock starts on the date the misappropriation was discovered, or should have been discovered through reasonable diligence. Trade secret theft often goes undetected for months or years, so this discovery rule matters. A former employee might quietly feed information to a competitor with no obvious sign until the competitor suddenly launches a suspiciously similar product.
The statute treats continuing misappropriation as a single claim. If a defendant acquires a trade secret in 2023 and keeps using it through 2026, the three-year period runs from when the plaintiff discovers, or reasonably should have discovered, the misappropriation. It does not restart with each new act of use. Missing the deadline is fatal. Courts have no discretion to extend it.
Whistleblower Immunity and the Employer Notice Requirement
Under 18 U.S.C. § 1833(b), individuals who disclose trade secrets to report suspected illegal activity are shielded from criminal and civil liability under any federal or state trade secret law. The immunity applies when the disclosure is made in confidence to a federal, state, or local government official or to an attorney, and only for the purpose of reporting or investigating a suspected legal violation. It also covers disclosures made in a court filing submitted under seal. The protection is not a license to share proprietary information publicly. It requires confidential disclosure to the right recipients for the right reasons.
Employers have a related obligation under § 1833(b)(3). Any contract or agreement that governs the use of trade secrets or confidential information has to include notice of this immunity. The notice can appear directly in the agreement, or the agreement can cross-reference a separate policy document that spells out the company’s reporting procedures for suspected legal violations. Skipping the notice has a real consequence. If the employer later sues that individual for trade secret misappropriation under the DTSA, the employer forfeits the right to recover exemplary damages or attorney fees. Given that exemplary damages can double the compensatory award, omitting a few paragraphs from an employment agreement can be very expensive.
Criminal Penalties
The DTSA’s civil remedies sit alongside the criminal provisions already in the Economic Espionage Act. Under 18 U.S.C. § 1832, stealing a trade secret related to interstate or foreign commerce is a federal crime. An individual convicted of trade secret theft faces up to 10 years in prison, a fine, or both. Organizations face steeper financial exposure: a fine of up to $5 million, or three times the value of the stolen trade secret, whichever is greater. The value calculation includes research, design, and other costs the organization avoided by stealing rather than developing the information itself.
These penalties are pursued by federal prosecutors, not private plaintiffs. A company that discovers misappropriation can report it to the FBI or the Department of Justice, but the decision to charge belongs to the government. Criminal prosecution tends to arise in cases involving large-scale corporate espionage or foreign government involvement rather than ordinary employee departures.
