Does South Carolina have a trade secret law?

The South Carolina Trade Secrets Act, S.C. Code §§ 39-8-10 to 39-8-130, was first enacted in 1992 and comprehensively rewritten by 1997 Act No. 38, effective May 21, 1997. Section 39-8-20(5)(b) requires considering the collective effect of items or procedures, not general knowledge of each individual item, while the economic-value and reasonable-secrecy requirements still apply. Under § 39-8-110, the Act displaces conflicting state tort and restitution claims arising from trade-secret disputes, making it the primary state-law vehicle for such cases in South Carolina courts. The federal Defend Trade Secrets Act applies alongside the state statute without preempting it (18 U.S.C. § 1838), allowing claimants to pursue both sets of claims in one proceeding.

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

S.C. Code § 39-8-20 defines a trade secret as information, including a formula, pattern, compilation, program, device, method, technique, product, system, process, design, prototype, procedure, or code, that satisfies two conditions. First, the information must derive independent economic value, actual or potential, from not being generally known to or readily ascertainable by proper means 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 its secrecy.

Section 39-8-20(5)(b) recognizes that a simple fact, item, procedure, or series of items or procedures may collectively make a substantial difference to process efficiency, production, or commercial strategy. Courts must consider their collective effect, rather than general knowledge of each individual item; the economic-value and secrecy requirements still apply.

Misappropriation under § 39-8-20 means acquiring a trade secret through improper means, such as theft, bribery, misrepresentation, or breach of a duty to maintain secrecy, or using or disclosing it without consent when the person knew or had reason to know it was obtained improperly or disclosed in breach of a confidence. Section 39-8-20 does not expressly name reverse engineering or independent development; independent discovery without improper acquisition, use, or breach of confidentiality does not itself establish misappropriation.

Remedies and the limitations period in South Carolina

The South Carolina Trade Secrets Act provides several categories of relief for successful claimants:

• Injunctions: Under § 39-8-50, a court may enjoin actual or threatened misappropriation for as long as the trade secret would otherwise remain protectable. In exceptional circumstances, a court may allow continued use on payment of a reasonable royalty rather than enter a prohibitory order.
• Damages: Section 39-8-40 authorizes recovery of actual loss from misappropriation or the defendant's unjust enrichment not already captured in that amount, or, as an alternative, a reasonable royalty for the period of unauthorized use or disclosure.
• Exemplary damages: The court may award exemplary damages up to twice the actual damages awarded under § 39-8-40(A) upon a finding of wilful, wanton, or reckless disregard of the plaintiff’s rights (§ 39-8-40(C)).
• Attorney fees: The court may award reasonable attorney fees to the prevailing party for a bad-faith misappropriation claim, a motion to terminate an injunction made or resisted in bad faith, or wilful misappropriation (§ 39-8-80).

The limitations period is three years. Under § 39-8-70, an action must be filed within three years after misappropriation is discovered or should have been discovered through the exercise of reasonable diligence. Continuing misappropriation constitutes a single claim accruing from the first act that was or should have been discovered. Businesses should investigate and document suspected misappropriation promptly, because delay can affect the right to sue and the scope of recoverable damages.

How the federal DTSA applies in South Carolina

The Defend Trade Secrets Act, 18 U.S.C. §§ 1836-1839, creates a federal civil cause of action for misappropriation when the trade secret relates to a product or service used in, or intended for use in, interstate or foreign commerce. Because the DTSA expressly preserves all state remedies (18 U.S.C. § 1838), South Carolina businesses may plead both DTSA and state-law claims in a single lawsuit, selecting the court and procedural tools that best suit the circumstances.

The DTSA provides one remedy not available under South Carolina's statute: a civil ex parte seizure order under § 1836(b)(2), which enables a court to order immediate seizure of materials containing a trade secret before the defendant receives notice, in extraordinary circumstances where ordinary injunctive relief would be inadequate. The DTSA's three-year limitations period from discovery (§ 1836(d)) matches South Carolina's under § 39-8-70.

South Carolina employers should review their nondisclosure and confidentiality agreements. Any agreement signed or updated after May 11, 2016 must include the DTSA whistleblower-immunity notice required by 18 U.S.C. § 1833(b)(3). An employer that omits this notice forfeits the right to seek exemplary damages and attorney fees from that individual under the DTSA, even when the misappropriation is willful.
