Ohio Trade Secret Laws: UTSA, Remedies & Deadlines

Ohio enacted the Ohio Uniform Trade Secrets Act in 1994, codified at Ohio Rev. Code §§ 1333.61 to 1333.69. The statute follows the Uniform Law Commission's UTSA model and differs from most UTSA states in one significant respect: Ohio's limitations period is four years from discovery under R.C. § 1333.66, one year longer than the three-year standard in both the UTSA and the federal DTSA. Both injunctive and monetary remedies are available, including up to three times the compensatory damages for willful and malicious misappropriation.

Does Ohio have a trade secret law?

Ohio enacted the Ohio Uniform Trade Secrets Act in 1994, codified at Ohio Rev. Code §§ 1333.61 to 1333.69, Chapter 1333 (codes.ohio.gov). The statute is based on the Uniform Law Commission's model Uniform Trade Secrets Act and provides the primary framework for civil trade-secret claims in Ohio. Section 1333.67 preempts conflicting civil tort and restitution claims based on trade-secret misappropriation, making the Ohio Uniform Trade Secrets Act the exclusive state civil remedy for these disputes. Ohio courts may consult UTSA commentary and decisions from other UTSA states when interpreting the Ohio statute. Criminal trade-secret theft is separately actionable under the federal Economic Espionage Act, 18 U.S.C. §§ 1831-1832.

What counts as a trade secret and misappropriation in Ohio?

Section 1333.61(D) of the Ohio Revised Code defines a trade secret as information, including all or part of scientific or technical information, designs, processes, procedures, formulas, patterns, compilations, programs, devices, methods, techniques, or improvements; business information or plans; financial information; or lists of names, addresses, or telephone numbers. The information must satisfy two conditions.

First, the information must derive independent economic value, actual or potential, from not being generally known to, and not being readily ascertainable by proper means by, any other person who can obtain economic value from its disclosure or use.

Second, the information must be the subject of reasonable efforts under the circumstances to maintain its secrecy.

Both conditions must be satisfied. Types of information that commonly qualify include customer and vendor lists, pricing models, software source code and algorithms, proprietary formulas, manufacturing specifications, and business or marketing plans, provided the owner has treated the information as confidential in actual practice.

Section 1333.61(B) defines misappropriation as acquiring a trade secret by improper means, such as theft, bribery, misrepresentation, or breach of a duty of confidentiality, or disclosing or using a trade secret without consent when the person knew or should have known it was improperly obtained. Ohio law does not treat reverse engineering of a lawfully obtained product or independent development as improper means. A competitor who discovers the same information through legitimate work has not committed misappropriation under the Ohio Act.

Remedies and the limitations period in Ohio

A court may grant an injunction under R.C. § 1333.62 to prevent actual or threatened misappropriation. In exceptional circumstances, if prohibiting use would be inequitable because the defendant has already incorporated the secret into a running product or process, the court may instead order payment of a reasonable royalty for a defined period.

Section 1333.63 governs monetary relief. A plaintiff may recover: (a) actual loss caused by the misappropriation plus the unjust enrichment received by the defendant that is not already captured in the actual-loss figure, or (b) a reasonable royalty for the period of misappropriation when neither actual loss nor unjust enrichment can be proved. When misappropriation is willful and malicious, the court may additionally award exemplary damages not exceeding three times the compensatory award.

Section 1333.64 permits an award of reasonable attorney fees to the prevailing party when a claim or motion is made or asserted in bad faith, or when willful and malicious misappropriation is found.

Ohio's limitations period under R.C. § 1333.66 is four years from the date misappropriation was discovered or, by the exercise of reasonable diligence, should have been discovered. This is a notable deviation from the UTSA's standard three-year period and from the federal DTSA's three-year period under 18 U.S.C. § 1836(d). A claimant who discovers misappropriation and files three and a half years later may retain an Ohio state-law claim while losing the federal DTSA claim. Claimants pursuing both theories should track each limitations period separately. Continuing misappropriation is treated as a single claim accruing from the first act the owner discovered or should have discovered.

How the federal DTSA applies in Ohio

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 requires the trade secret to relate to a product or service used in, or intended for use in, interstate or foreign commerce, a condition most Ohio business trade secrets satisfy. Because the DTSA expressly does not preempt state law (18 U.S.C. § 1838), Ohio claimants routinely plead both the Ohio Uniform Trade Secrets Act and the DTSA in a single lawsuit.

The difference in limitations periods is an important practical point. Ohio's Act allows four years from discovery under R.C. § 1333.66; the DTSA allows only three years from discovery under 18 U.S.C. § 1836(d). A claimant who waits three years and three months to sue retains the state claim but loses the federal one. Practitioners and claimants should calendar deadlines for each theory independently.

Two additional DTSA features supplement Ohio state remedies. First, a federal court may issue 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, 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 the misappropriation is deliberate.

Protecting trade secrets in Ohio: practical steps

Because reasonable efforts to maintain secrecy are a definitional element under R.C. § 1333.61(D), documented protective practices are both a legal requirement and a business necessity. Ohio courts assess whether protection measures were proportionate to the value of the information and the circumstances of the enterprise. Common protective steps 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 systems and files containing sensitive information
• Physical security measures for facilities and paper records holding proprietary data
• Consistent and visible marking of documents and materials as confidential or proprietary
• Structured employee offboarding procedures covering device return, credential revocation, and written reminders of post-employment confidentiality obligations

Ohio's diverse economy across manufacturing, financial services, healthcare, and technology means that a broad range of business information may qualify for trade-secret protection. Consistent documentation of security practices, and enforcement of those practices in day-to-day operations, strengthens the reasonable-efforts element if a claim is ever litigated.

This is general legal information, not legal advice. It describes Ohio trade-secret law under Ohio Rev. Code §§ 1333.61 to 1333.69 and the federal DTSA as of 2026-06-25 and does not address your specific facts. Trade-secret disputes are fact-intensive and deadlines are strict. Consult an attorney licensed in Ohio before acting.

Frequently Asked Questions

What qualifies as a trade secret under Ohio law?

Under R.C. § 1333.61(D), information qualifies as a trade secret if it derives independent economic value from not being generally known or readily ascertainable by those who can benefit from its use or disclosure, and the owner takes reasonable efforts to maintain secrecy. Customer lists, formulas, software source code, pricing models, and manufacturing specifications can all qualify if both conditions are satisfied. Reverse engineering of a lawfully obtained product and independent development are not improper means and do not constitute misappropriation under the Ohio Act.

How long do I have to sue for trade secret misappropriation in Ohio?

Four years from when misappropriation was discovered or should have been discovered through reasonable diligence, under R.C. § 1333.66. Ohio's four-year period is one year longer than the UTSA's standard three-year period and the federal DTSA's three-year period (18 U.S.C. § 1836(d)). Claimants pursuing both state and federal claims should track each limitations deadline separately, since the federal clock runs one year earlier than the state clock.

What remedies does the Ohio Uniform Trade Secrets Act provide?

Ohio courts may award injunctions under R.C. § 1333.62, actual damages plus unjust enrichment or a reasonable royalty under R.C. § 1333.63, and exemplary damages up to three times the compensatory award for willful and malicious misappropriation. Attorney fees are available under R.C. § 1333.64 when misappropriation is willful and malicious or when a claim is made in bad faith.

Do Ohio confidentiality agreements need a DTSA whistleblower notice?

Yes. Any nondisclosure or confidentiality agreement with an employee or contractor that was signed or updated after May 11, 2016 must include the whistleblower-immunity notice required by 18 U.S.C. § 1833(b)(3). An employer who omits this notice loses the right to recover DTSA exemplary damages and attorney fees from that individual, even when misappropriation is willful and deliberate.

Does Ohio's trade secret statute preempt other tort claims?

Yes. R.C. § 1333.67 displaces conflicting civil claims based on misappropriation of a trade secret that would otherwise arise under Ohio common law, including tort and restitution theories. Contract claims and criminal statutes are not displaced. This means that when the core wrong is trade-secret misappropriation, the Ohio Uniform Trade Secrets Act is generally the exclusive state civil remedy and supersedes competing tort theories.
