Defend Trade Secrets Act — Federal Trade Secret Protection & Economic Espionage

The Defend Trade Secrets Act of 2016 (18 U.S.C. § 1836) created the first federal civil cause of action for trade secret misappropriation — allowing companies to sue in federal court when someone steals their trade secrets for use in products or services in interstate or foreign commerce. Before the DTSA, trade secret theft was a federal crime (under the Economic Espionage Act of 1996, 18 U.S.C. §§ 1831–1832) but civil remedies were available only under state law — primarily the Uniform Trade Secrets Act adopted by 48 states. The DTSA didn't replace state law — it added a parallel federal option, giving trade secret owners access to federal courts, federal discovery procedures, and a unique remedy: the power to obtain an ex parte seizure order (a court order issued without notice to the defendant, allowing seizure of misappropriated trade secrets to prevent dissemination). The Act also established whistleblower immunity — protecting employees who disclose trade secrets in confidence to government officials or attorneys for the purpose of reporting suspected law violations. Trade secrets are enormously valuable — alongside patents and trademarks, they form a core pillar of U.S. intellectual property protection — and the Commission on the Theft of American Intellectual Property estimated that trade secret theft costs the U.S. economy $180–$540 billion per year. Criminal penalties for trade secret theft — prosecuted under federal criminal law — include up to $5 million and 10 years imprisonment for economic espionage (foreign government benefit) and $250,000 and 10 years for commercial trade secret theft.

Current Law (2026)

Legal Authority

• 18 U.S.C. § 1831 — Economic espionage (criminal penalties for trade secret theft benefiting a foreign government, foreign instrumentality, or foreign agent — up to $5M and 10 years for individuals; $10M or 3× value for organizations)
• 18 U.S.C. § 1832 — Theft of trade secrets (criminal penalties for commercial trade secret theft — up to $250K and 10 years for individuals; $5M for organizations)
• 18 U.S.C. § 1833 — Exceptions and whistleblower immunity (provides immunity from liability for individuals who disclose trade secrets in confidence to government officials or attorneys for purpose of reporting law violations; employers must notify employees of this immunity in any NDA or employment agreement)
• 18 U.S.C. § 1836 — Civil proceedings (creates federal civil cause of action for misappropriation of trade secrets used in interstate or foreign commerce; authorizes injunctions, damages, and ex parte seizure orders)
• 18 U.S.C. § 1839 — Definitions (trade secret: all forms of business, scientific, technical, economic, engineering, or financial information that the owner has taken reasonable measures to keep secret and that derives independent economic value from not being generally known)

How It Works

The DTSA defines trade secrets broadly: all forms of financial, business, scientific, technical, economic, or engineering information — including patterns, plans, compilations, formulas, methods, processes, programs, or code — that the owner has taken reasonable measures to keep secret and that derives independent economic value from not being generally known or readily ascertainable. Customer lists, algorithms, manufacturing processes, chemical formulas, pricing strategies, and source code all qualify if they've been maintained as secret and their secrecy is what makes them valuable. When misappropriation occurs — either through acquisition by improper means or unauthorized disclosure or use — the DTSA allows the owner to sue in federal district court for: (1) injunctive relief to stop further use or disclosure (though courts cannot enjoin someone from taking a new job solely because of what they know); (2) actual damages plus the infringer's unjust enrichment, or alternatively a reasonable royalty; and (3) exemplary damages up to 2× actual damages plus attorney fees for willful and malicious misappropriation.

The DTSA's most dramatic remedy is the ex parte seizure order — available only in extraordinary circumstances where a standard injunction would be inadequate, allowing a federal marshal to seize misappropriated secrets (laptops, drives, documents) from the defendant's possession without advance notice. Courts rarely grant these; the requirements are stringent. Separately, the DTSA includes a critical whistleblower immunity: individuals who disclose trade secrets in confidence to a government official or attorney solely for reporting a suspected legal violation are immune from trade secret liability. Employers must include notice of this immunity in every NDA, confidentiality agreement, and employment contract — failure to do so bars the employer from recovering exemplary damages or attorney fees in any subsequent DTSA action against that employee.

How It Affects You

If you're a business that owns trade secrets and believes they've been misappropriated: The DTSA gives you a federal civil remedy, but the prerequisite is proving you took "reasonable measures" to maintain secrecy — and that burden rests on you.

What qualifies as "reasonable measures": Courts evaluate this holistically, but the baseline elements include: (1) NDAs and confidentiality agreements with every employee, contractor, and business partner who accesses the trade secret; (2) Access controls — restricting the secret to those who need it (documented need-to-know), password protection, encryption for digital secrets; (3) Physical security — locked files, secure lab spaces, visitor controls; (4) Marking — labeling confidential documents and systems as "Confidential" or "Proprietary"; (5) Employee training — regular awareness training on what constitutes trade secrets and how to protect them; (6) Exit processes — exit interviews reminding departing employees of their obligations, return of company property, revocation of access on the day of departure. Courts have denied trade secret protection where companies had weak NDAs, shared secrets broadly without restriction, or failed to mark materials as confidential.

Filing a DTSA civil complaint: File in federal district court where the defendant is located or where the misappropriation occurred, or where the company whose secrets were stolen is headquartered (the DTSA provides multiple venue options). The statute of limitations is 3 years from the date you discovered (or should have discovered) the misappropriation — start your clock from when you first had reason to know, not from when you hired lawyers. Seek a temporary restraining order and preliminary injunction at the time of filing if the defendant is currently using or about to disclose the secrets — this is the most time-sensitive element of DTSA litigation.

The ex parte seizure order — the DTSA's most dramatic remedy — is available only in extraordinary circumstances where an injunction would be inadequate and the defendant would destroy the secrets if given notice. Courts are reluctant to grant these without very strong showings. If you're considering seeking an ex parte seizure, work with experienced IP litigation counsel: an improperly obtained seizure order exposes you to sanctions and damages to the defendant.

If you're an employee leaving a job: The DTSA protects you as much as it protects employers — specifically through the anti-injunction provision: courts cannot issue an injunction that "prevents a person from entering into an employment relationship" or conditions employment "based merely on the information the person knows" (18 U.S.C. § 1836(b)(3)(A)(i)(I)). In other words, your employer cannot use the DTSA to prevent you from taking a new job just because you know the company's trade secrets.

What you can and cannot take: You can take: your general skills, industry knowledge, relationships you developed, and anything in your memory that you accumulated through experience. You cannot take: downloaded files, copied documents, exported databases, customer lists transferred to personal devices, or any materials you physically removed. The most common fact pattern in DTSA cases involves employees who download files to personal devices or forward emails to personal accounts in the weeks before departure. Courts routinely infer misappropriation from forensic evidence of large downloads or data transfers shortly before resignation.

The whistleblower immunity under 18 U.S.C. § 1833(b) protects you if you're reporting suspected wrongdoing. You are immune from trade secret liability if you disclose a trade secret in confidence to a government official (regulatory agency, law enforcement) or to your attorney solely for the purpose of reporting or investigating a suspected violation of law. This immunity exists even if your employer's NDA doesn't acknowledge it — it's statutory. If you're considering going to the SEC, OSHA, EPA, DOJ, or any other federal or state agency about conduct at your employer, and you need to share confidential information to make your case, the DTSA whistleblower immunity protects you from being sued for misappropriation.

If you're an employer drafting NDAs or employment agreements: The DTSA has a mandatory notice requirement: 18 U.S.C. § 1833(b)(3) requires that any NDA, non-disclosure agreement, or employment contract entered into after May 11, 2016 must include — or incorporate by reference to a policy containing — the whistleblower immunity notice. Specifically, the agreement must state that the employee "shall not be held criminally or civilly liable under any Federal or State trade secret law for the disclosure of a trade secret that... is made in confidence to a Federal, State, or local government official... or to an attorney... solely for the purpose of reporting or investigating a suspected violation of law."

If you fail to include this notice in your NDAs, you cannot recover exemplary (punitive) damages or attorney fees against that employee in a DTSA case — even if they committed willful misappropriation. Update your NDA templates and employment agreements to include the notice. The simplest approach: add the statutory language to your standard confidentiality section or create a company policy and reference it in all agreements.

Your NDA should also be careful not to prohibit employees from exercising their whistleblower rights. An NDA that says "you cannot disclose anything to anyone" without a carve-out for legally protected disclosures to government agencies may violate the National Labor Relations Act and SEC whistleblower rules — and will not prevent the employee from making protected disclosures anyway (they're immune by statute).

State Variations

The DTSA supplements but does not preempt state trade secret law (see Federal Preemption Doctrine for when federal law does override state law):

• 48 states have adopted the Uniform Trade Secrets Act (UTSA) — state and federal remedies may be pursued in parallel
• State definitions of trade secrets and misappropriation closely align with the DTSA but may differ in details
• Some states (notably New York) have not adopted the UTSA and rely on common law trade secret protection
• State courts may apply different standards for injunctive relief and damages
• Non-compete enforceability (which often intersects with trade secret protection) varies dramatically by state

Implementing Regulations

The Defend Trade Secrets Act (18 U.S.C. §§ 1836–1839) is self-executing — it creates a federal civil cause of action for trade secret misappropriation with no implementing regulations in the CFR.

• Federal Rules of Civil Procedure govern DTSA litigation, including ex parte seizure orders under § 1836(b)(2), which have specific procedural requirements built into the statute itself

Pending Legislation

No standalone DTSA reform bills have been introduced in the 119th Congress. Trade secret and IP enforcement provisions appear in broader intellectual property legislation — see Patent Law and Economic Espionage Act.

Recent Developments

DTSA litigation has grown rapidly since 2016, with thousands of federal cases filed. Courts have developed a substantial body of case law on what constitutes "reasonable measures" to maintain secrecy, the scope of the ex parte seizure remedy (rarely granted), and the interaction between DTSA claims and state trade secret law. The whistleblower immunity provision has been the subject of increasing litigation — particularly around whether employers' failure to include the immunity notice in NDAs bars exemplary damages. DOJ has pursued high-profile economic espionage prosecutions under § 1831, particularly involving Chinese state-sponsored theft of U.S. trade secrets in technology, manufacturing, and pharmaceuticals.
