What Is the Defend Trade Secrets Act?

The Defend Trade Secrets Act (DTSA) is a U.S. federal law that lets trade secret owners bring civil lawsuits in federal court when trade secrets are misappropriated. It created a federal civil cause of action while leaving state trade secret law in place.

The law matters because trade secrets can be among a company's most valuable assets. Customer lists, formulas, source code, manufacturing processes, pricing models, business plans, and technical know-how may be protected if they are secret, economically valuable, and subject to reasonable measures to keep them secret.

Key Takeaways

  • The DTSA created a federal civil remedy for trade secret misappropriation.
  • It does not replace state trade secret law.
  • Trade secret owners must take reasonable steps to protect secrecy.
  • The law includes whistleblower-immunity notice provisions.
  • Business value depends on documentation, access controls, contracts, and enforcement readiness.

How the DTSA Works

A trade secret owner can sue in federal court if a trade secret related to a product or service used in interstate or foreign commerce is misappropriated. Misappropriation can include improper acquisition, disclosure, or use of a protected trade secret. Remedies may include injunctions, damages, exemplary damages in certain cases, and attorney fees under defined conditions.

The law also includes an extraordinary seizure remedy in limited circumstances, but that tool is narrow and court-supervised. For most businesses, the practical DTSA work happens before litigation: identifying trade secrets, limiting access, using confidentiality agreements, training employees, managing vendors, and documenting security measures.

Business Controls That Matter

Control

Why it matters

Access limits

Shows that the company treated information as secret.

NDAs and employment agreements

Clarify confidentiality duties and permitted use.

Data controls

Reduce copying, downloading, and unauthorized sharing.

Exit procedures

Help recover devices, credentials, and confidential files.

Trade secret inventory

Makes protected information easier to identify in a dispute.

Financial Consequences

Trade secret loss can damage margins, pricing power, product roadmaps, customer relationships, and competitive advantage. A stolen manufacturing process or source-code base may save a competitor years of investment. A leaked customer list can reduce the value of an acquisition or partnership.

The DTSA can improve enforcement options, but it does not protect sloppy secrecy practices. If a company cannot show what the trade secret was or how it was protected, the legal claim becomes weaker.

Whistleblower-Immunity Notice

The DTSA includes immunity for certain confidential disclosures made to government officials or attorneys for reporting or investigating suspected legal violations, and for certain sealed court filings. Employers seeking some remedies should pay attention to DTSA notice language in confidentiality agreements and related documents.

This is one reason trade secret compliance overlaps with employment law, legal operations, and human resources rather than sitting only with the legal department.

Example

A departing engineer downloads restricted design files before joining a competitor. If those files contain protected trade secrets and the company used reasonable secrecy measures, the DTSA may provide a federal path to seek relief. If the files were widely shared without controls, the claim may be harder to sustain.

DTSA and State Law

The DTSA did not wipe away state trade secret law. Many disputes still include both federal and state claims. That dual structure can matter for remedies, procedure, timing, and settlement leverage. A company protecting sensitive information should therefore think about trade secret governance broadly, not only about one federal statute.

The DTSA also makes trade secret management more board-relevant. A company that depends on confidential know-how should treat secrecy controls as part of enterprise risk management, not only as a legal response after theft occurs.

The Bottom Line

The DTSA gives trade secret owners a federal civil enforcement tool. Its practical value depends on more than litigation rights: businesses must identify, protect, monitor, and document their trade secrets before a dispute begins.
