Does Kentucky have a trade secret law?
Yes. Kentucky enacted the Kentucky Uniform Trade Secrets Act in 1990, codified at Ky. Rev. Stat. §§ 365.880 to 365.900. The statute adopts the UTSA framework that 48 other states and the District of Columbia use, aligning Kentucky's definitions, misappropriation standard, and remedies with the national model. The law covers all forms of qualifying confidential business information, including formulas, customer databases, processes, methods, programs, and financial strategies, without requiring any registration or public disclosure. Ky. Rev. Stat. § 365.892 preempts conflicting civil claims under Kentucky law that arise from the same set of facts as a trade-secret misappropriation claim, directing those disputes through the Kentucky Uniform Trade Secrets Act.
What counts as a trade secret and misappropriation in Kentucky?
Ky. Rev. Stat. § 365.880 defines a trade secret as information, including a formula, pattern, compilation, program, data, device, method, technique, or process, that satisfies two requirements: (1) the information derives independent economic value, actual or potential, from not being generally known to or readily ascertainable by proper means by other persons who can profit from its disclosure or use; and (2) the information is the subject of efforts that are reasonable under the circumstances to maintain its secrecy.
Both elements must be satisfied. A Kentucky employer's proprietary client list, internal pricing structure, software source code, or manufacturing method can qualify as long as the owner actively protects it and derives a competitive advantage from its secrecy. Loss of secrecy by any means ends trade-secret protection permanently.
Misappropriation under Ky. Rev. Stat. § 365.880 takes two forms. The first is acquisition of a trade secret by improper means, which includes theft, bribery, misrepresentation, breach of a duty to maintain secrecy, or similar misconduct. The second is disclosure or use of a trade secret without consent by a person who knew or had reason to know it was acquired by improper means, or who was under a duty of confidence and exceeded that duty.
Reverse engineering a lawfully obtained product to discover the trade secret it embodies is a proper means and is not misappropriation under Kentucky law. Independent development of the same information by a third party is likewise lawful.
Remedies and the limitations period in Kentucky
Ky. Rev. Stat. § 365.882 authorizes injunctive relief to prevent actual or threatened misappropriation for as long as the trade secret would otherwise remain protectable. Where an injunction would be inequitable, courts may require the misappropriator to pay a reasonable royalty for continued use of the secret for a reasonable period.
Monetary remedies under Ky. Rev. Stat. § 365.884 include actual damages for losses caused by the misappropriation, plus any unjust enrichment not already reflected in the damages figure, or a reasonable royalty as an alternative measure. For willful and malicious misappropriation, Ky. Rev. Stat. § 365.884 permits exemplary damages of up to twice the compensatory award. Attorney fees may be awarded under Ky. Rev. Stat. § 365.886 when the misappropriation was willful and malicious, or when a claim or defense was made in bad faith.
Kentucky's limitations period is three years (Ky. Rev. Stat. § 365.890), running from the date misappropriation was discovered or, by reasonable diligence, should have been discovered. Continuing misappropriation is treated as a single claim; the period runs from the first act the owner discovered or reasonably should have discovered, not from the most recent act.
How the federal DTSA applies in Kentucky
The Defend Trade Secrets Act of 2016 (18 U.S.C. §§ 1836-1839) gives Kentucky businesses a parallel federal civil claim when the misappropriated secret relates to a product or service used in or intended for use in interstate or foreign commerce. The DTSA does not displace Ky. Rev. Stat. §§ 365.880 to 365.900 (18 U.S.C. § 1838), and Kentucky owners routinely bring both state and federal claims together in the same lawsuit.
The DTSA provides procedural tools that state law does not offer, including an ex parte civil seizure application in extraordinary circumstances to seize misappropriated materials before they can be concealed or destroyed (18 U.S.C. § 1836(b)(2)). The federal limitations period is three years from discovery (18 U.S.C. § 1836(d)), matching Kentucky's state period.
A compliance obligation applies directly to Kentucky employers: any confidentiality agreement, nondisclosure agreement, or employment agreement governing confidential information that was signed or updated after May 11, 2016 must include the DTSA whistleblower-immunity notice required by 18 U.S.C. § 1833(b)(3). Omitting that notice forfeits the right to recover exemplary damages and attorney fees from that employee under the DTSA, even for willful misappropriation. The federal Economic Espionage Act (18 U.S.C. §§ 1831-1832) also criminalizes trade-secret theft occurring in Kentucky.

Frequently Asked Questions
What qualifies as a trade secret under Kentucky law?
Under Ky. Rev. Stat. § 365.880, information qualifies as a trade secret if it derives independent economic value from not being generally known or readily ascertainable by others who could profit from it, and the owner takes steps reasonable under the circumstances to maintain its secrecy. Common examples include customer lists, formulas, software source code, manufacturing processes, and business strategies. Protection ends permanently once the information becomes public.
How long do I have to file a trade secret lawsuit in Kentucky?
Three years from the date misappropriation was discovered or should have been discovered through reasonable diligence (Ky. Rev. Stat. § 365.890). For continuing misappropriation, the period begins from the first act the owner discovered or should have discovered, not the most recent one. The federal DTSA claim carries the same three-year period (18 U.S.C. § 1836(d)), so prompt investigation is critical in either forum.
What remedies are available for trade secret theft in Kentucky?
Injunctions to prevent actual or threatened misappropriation (Ky. Rev. Stat. § 365.882), actual damages plus unjust enrichment or a reasonable royalty (Ky. Rev. Stat. § 365.884), exemplary damages up to twice the compensatory award for willful and malicious misappropriation, and attorney fees for willful and malicious or bad-faith claims (Ky. Rev. Stat. § 365.886). Federal DTSA remedies under 18 U.S.C. § 1836(b)(3) can be sought alongside Kentucky claims.
Do NDAs and confidentiality agreements protect trade secrets in Kentucky?
Yes. Written confidentiality agreements help satisfy the reasonable-secrecy-measures element required by Ky. Rev. Stat. § 365.880. Any agreement signed or updated after May 11, 2016 must also include the DTSA whistleblower-immunity notice (18 U.S.C. § 1833(b)). Omitting it forfeits exemplary damages and attorney fees from that employee under federal law, even for willful theft. Kentucky law imposes no parallel forfeiture, but including the notice preserves all available federal remedies.
How does the federal DTSA interact with Kentucky trade secret law?
The DTSA (18 U.S.C. §§ 1836-1839) provides a parallel federal claim when the secret relates to interstate or foreign commerce. It does not preempt Ky. Rev. Stat. §§ 365.880 to 365.900 (18 U.S.C. § 1838), so owners can plead both in the same lawsuit. DTSA-only tools include civil ex parte seizure (18 U.S.C. § 1836(b)(2)) and the whistleblower notice requirement. Both laws share the UTSA-derived two-part trade-secret definition and a three-year limitations period.
