Maine Trade Secret Laws: UTSA, Remedies & Deadlines

Maine's Uniform Trade Secrets Act, Me. Rev. Stat. tit. 10, §§ 1541 to 1548, has protected proprietary business information in Maine since 1987. A civil claim for misappropriation must be brought within four years of discovering the wrong (§ 1547), and the federal Defend Trade Secrets Act provides a concurrent federal remedy without displacing the state statute.

Does Maine have a trade secret law?

Maine enacted the Maine Uniform Trade Secrets Act in 1987, codified at Me. Rev. Stat. tit. 10, §§ 1541 to 1548. The statute follows the framework developed by the Uniform Law Commission and governs civil claims by any person or entity whose trade secrets are misappropriated in Maine. It defines both trade secret and misappropriation, prescribes available remedies, and fixes the four-year limitations period. Under § 1548, the statute displaces conflicting state tort and restitution claims that would otherwise apply to trade-secret disputes. It preserves contractual remedies, other civil remedies not based on trade-secret misappropriation, and criminal remedies; § 1548 also preserves legally required disclosures and the Maine Tort Claims Act. The federal Defend Trade Secrets Act applies alongside Maine's statute without preempting it (18 U.S.C. § 1838), so a claimant may assert both sets of claims in a single lawsuit and take advantage of whichever forum best suits the facts.

What counts as a trade secret and misappropriation in Maine?

The Maine Uniform Trade Secrets Act, Me. Rev. Stat. tit. 10, §§ 1541 to 1548, defines a trade secret as information, including a formula, pattern, compilation, program, device, method, technique, or process, 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 others who can profit from its disclosure or use. Second, the owner must have made efforts that are reasonable under the circumstances to maintain its secrecy. Common categories include customer and supplier lists, manufacturing processes, source code, pricing strategies, and proprietary formulas.

Misappropriation under the Maine Uniform Trade Secrets Act means acquiring a trade secret through improper means, such as theft, bribery, espionage, or breach of a duty of confidentiality, or using or disclosing it without consent when the person knew or had reason to know the secret was improperly obtained. Reverse engineering a product obtained through proper means and independent development of equivalent information are lawful under the Act and do not amount to misappropriation.

Remedies and the limitations period in Maine

The Maine Uniform Trade Secrets Act provides several categories of relief for successful claimants:

• Injunctions: Under § 1543, a court may enjoin actual or threatened misappropriation for as long as the information would otherwise remain protectable. In exceptional circumstances, a court may permit ongoing use conditioned on payment of a reasonable royalty.
• Damages: Section 1544(1) allows recovery of actual loss from misappropriation plus unjust enrichment of the defendant not already captured in that loss, or, as an alternative, a reasonable royalty for the period of unauthorized use.
• Exemplary damages: When misappropriation is willful and malicious, the court may award exemplary damages up to twice the compensatory award (§ 1544(2)).
• Attorney fees: The court may award reasonable fees to the prevailing party for willful and malicious misappropriation, a bad-faith misappropriation claim, or a motion to terminate an injunction made or resisted in bad faith (§ 1545).

The limitations period is four years. Under § 1547, an action must be brought within four years after the misappropriation is discovered or should have been discovered through the exercise of reasonable diligence. Continuing misappropriation is treated as a single claim accruing from the first act that was or reasonably should have been discovered. Because this rule compresses the window, businesses should investigate and document suspected misappropriation as soon as it comes to their attention.

How the federal DTSA applies in Maine

The Defend Trade Secrets Act, 18 U.S.C. §§ 1836-1839, creates a federal civil action for trade-secret misappropriation when the 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), Maine businesses may plead both DTSA and state claims together and select the forum and procedural tools that fit the situation.

The DTSA provides one remedy not available under Maine'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 other injunctive relief would be inadequate. The DTSA's three-year limitations period from discovery (§ 1836(d)) differs from Maine's four-year period under § 1547.

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