North Carolina Trade Secret Laws: Trade Secrets Protection Act, Remedies & Deadlines

North Carolina's Trade Secrets Protection Act, N.C. Gen. Stat. §§ 66-152 to 66-157, enacted in 1981, provides civil remedies for trade secret misappropriation under the state's own legislative framework. The Uniform Law Commission does not classify North Carolina's Act as a formal adoption of the model Uniform Trade Secrets Act; North Carolina's statute predates the finalized UTSA and follows its own structure. Civil claims must be filed within three years of discovery under § 66-157.

Does North Carolina have a trade secret law?

North Carolina enacted the Trade Secrets Protection Act in 1981, codified at N.C. Gen. Stat. §§ 66-152 to 66-157, Article 24 of Chapter 66 (ncleg.gov). This statute is North Carolina's own legislative framework for trade-secret protection. The Uniform Law Commission does not classify North Carolina's Act as a formal adoption of the model Uniform Trade Secrets Act: North Carolina's law predates the finalized UTSA and, while it borrows related concepts such as the two-part definition and the misappropriation framework, it differs from the UTSA model in meaningful structural respects. Practitioners researching North Carolina trade-secret disputes should consult the state's own statute and case law directly rather than assuming that UTSA commentary from other jurisdictions controls the analysis. The Act covers civil claims only; criminal conduct involving trade secrets may be pursued under the federal Economic Espionage Act, 18 U.S.C. §§ 1831-1832, or applicable state criminal statutes.

What counts as a trade secret and misappropriation in North Carolina?

Section 66-152(3) of the North Carolina General Statutes defines a trade secret as business or technical information, including but not limited to a formula, pattern, program, device, compilation of information, method, technique, or process, that satisfies two conditions.

First, the information must derive independent actual or potential commercial value from not being generally known to, or readily ascertainable through independent development or reverse engineering by, persons who can obtain economic value from its disclosure or use.

Second, the owner must have taken steps that are reasonable under the circumstances to maintain the secrecy of the information.

Both conditions must be satisfied. Common examples of qualifying information include customer and supplier lists, pricing strategies, software source code, proprietary formulas, manufacturing specifications, and business development plans, provided the owner has treated the information as confidential in practice.

Section 66-152(1) defines misappropriation as acquiring, disclosing, or using another's trade secret without express or implied authority or consent. It excludes information reached by independent development, reverse engineering, or obtained from someone entitled to disclose it. Section 66-152(2) defines person, not improper means; the Act does not contain a separate definition of improper means.

Remedies and the limitations period in North Carolina

Section 66-154(a) permits preliminary injunctions against actual or threatened misappropriation and requires a permanent injunction upon a judgment finding misappropriation, subject to its stated exceptions. If prohibiting use after judgment would be unreasonable, § 66-154(a)(1) permits use conditioned on a reasonable royalty. Section 66-154(a)(2) separately protects qualifying good-faith recipients who substantially changed position in reliance on future use, while allowing a royalty; these are injunction provisions, not a royalty-in-lieu-of-damages measure under subsection (b).

Section 66-154(b) permits actual damages measured by the greater of economic loss or unjust enrichment caused by misappropriation. It does not specify a royalty alternative. Under § 66-154(c), the trier of fact may award punitive damages for willful and malicious misappropriation. Chapter 1D applies to statutory punitive-damages claims under § 1D-10, and § 1D-25(b) generally limits the award to the greater of 3x compensatory damages or $250,000.

Section 66-154(d) permits an award of reasonable attorney fees to the prevailing party when a misappropriation claim is made in bad faith, or when willful and malicious misappropriation is found.

The limitations period under § 66-157 is three years from the date misappropriation was discovered or, by the exercise of reasonable diligence, should have been discovered. Section 66-157 does not state a separate continuing-misappropriation rule; the filing deadline depends on when the misappropriation complained of was or reasonably should have been discovered.

Section 66-155 provides a prima facie proof framework: substantial evidence must show both knowledge or reason to know of the secret and either a specific opportunity to acquire it for disclosure or use, or acquisition, disclosure, or use without the owner's authority or consent. Substantial evidence of independent development, reverse engineering, or receipt from someone entitled to disclose rebuts that showing, and other legal defenses remain available.

Under § 66-156, courts must take reasonable steps to protect an alleged trade secret during litigation. These may include protective orders, private hearings, sealed records, and restrictions on further disclosure.

How the federal DTSA applies in North Carolina

The Defend Trade Secrets Act, 18 U.S.C. §§ 1836-1839, has provided a federal civil remedy for trade-secret misappropriation since May 11, 2016. The DTSA applies when the trade secret relates to a product or service used in, or intended for use in, interstate or foreign commerce, a condition most North Carolina business trade secrets satisfy. Because the DTSA expressly does not preempt state law (18 U.S.C. § 1838), a North Carolina claimant may plead both the state Trade Secrets Protection Act and the DTSA in a single action.

Two DTSA-specific remedies supplement North Carolina state law. First, a federal court may enter a civil ex parte seizure order in extraordinary circumstances to prevent the propagation or disclosure of a misappropriated secret before the defendant receives notice (18 U.S.C. § 1836(b)(2)). Second, the DTSA's limitations period is three years from discovery (§ 1836(d)), matching North Carolina's three-year period under § 66-157.

Under 18 U.S.C. § 1833(b)(3), any confidentiality or employment agreement signed or updated after May 11, 2016 must notify the employee of the statutory whistleblower immunity: employees may not be held liable for disclosing a trade secret to a government official or attorney solely to report a suspected legal violation. An employer who omits this notice from a covered agreement forfeits DTSA exemplary damages and attorney fees against that individual, even when misappropriation is deliberate.

Protecting trade secrets in North Carolina: practical steps

Because reasonable measures to maintain secrecy are a definitional element under § 66-152(3), a company's protective practices are legally relevant, not merely advisable. North Carolina courts assess whether protection was proportionate to the value of the information and the circumstances of the business. Practical protective measures include:

• Written nondisclosure and confidentiality agreements with employees, contractors, and business partners, updated after May 11, 2016 to include the DTSA whistleblower-immunity notice
• Role-based digital access controls and encryption for files and systems housing sensitive business information
• Physical security measures for facilities and paper records containing proprietary data
• Consistent and visible marking of documents and materials as confidential or proprietary
• Structured offboarding procedures for departing employees covering device return, credential revocation, and written reminders of continuing confidentiality obligations

Courts assess whether a company treated information as secret in actual practice. A policy that is documented but not enforced, or a secret that is broadly shared internally without controls, may undermine trade-secret status even when other measures are in place.

This is general legal information, not legal advice. It describes North Carolina trade-secret law under N.C. Gen. Stat. §§ 66-152 to 66-157 and the federal DTSA as of 2026-06-25 and does not address your specific circumstances. Trade-secret disputes are fact-intensive and deadlines are strict. Consult an attorney licensed in North Carolina before acting.
