Montana Trade Secret Laws: UTSA, Remedies & Deadlines

Montana enacted the Montana Uniform Trade Secrets Act, Mont. Code §§ 30-14-401 to 30-14-409, in 1985, placing it among the earlier states to adopt a UTSA-based civil framework for trade secret protection. The statute closely tracks the Uniform Trade Secrets Act model. Claims must be brought within three years of discovery under § 30-14-407.

Does Montana have a trade secret law?

Montana enacted the Montana Uniform Trade Secrets Act (MUTSA) in 1985, codified at Mont. Code §§ 30-14-401 to 30-14-409. Montana was among the earlier US states to adopt the Uniform Law Commission's model act, and its three-decade-plus track record means practitioners and courts can draw on a substantial body of Montana case law as well as persuasive UTSA precedent from other jurisdictions. The statute provides a comprehensive civil framework for trade secret misappropriation claims covering improper acquisition, unauthorized disclosure, and unauthorized use. Montana's act includes all of the core UTSA provisions: definitions, injunctive relief, damages, attorney fees, a duty of courts to preserve secrecy in litigation, the limitations period, and preemption of competing tort claims. Federal criminal liability for intentional trade secret theft remains available under the Economic Espionage Act, 18 U.S.C. §§ 1831-1832.

What counts as a trade secret and misappropriation in Montana?

Section 30-14-402 of the Montana Code 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, and not being readily ascertainable by proper means by, other persons who can obtain economic value from its disclosure or use.

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

Both conditions are conjunctive; failing either defeats trade-secret status. Categories of information that can qualify include customer lists, pricing models, manufacturing processes, proprietary software and algorithms, financial projections, and business development plans, provided genuine protective measures are in place. Sharing information with employees or contractors under written confidentiality obligations does not destroy protection, but broad disclosure without restriction can.

Under § 30-14-402, misappropriation means acquiring a trade secret by improper means, which includes theft, bribery, misrepresentation, breach or inducement of a breach of a duty to maintain secrecy, or disclosing or using a trade secret without consent by a person who knew or had reason to know the secret was acquired improperly or in violation of a confidentiality obligation. Reverse engineering a lawfully obtained product and independently developing the same information are expressly lawful under Montana law and do not constitute misappropriation.

Remedies and the limitations period in Montana

Section 30-14-403 authorizes courts to grant injunctions to prevent actual or threatened misappropriation. A court may extend an injunction beyond the period of misappropriation to eliminate any commercial advantage the defendant gained, and may condition injunctive relief on payment of a reasonable royalty when an absolute prohibition would be inequitable.

Section 30-14-404 governs damages. A prevailing claimant may recover actual loss caused by the misappropriation plus the misappropriator's unjust enrichment not already captured in the actual-loss figure, or a reasonable royalty for the period of unauthorized use in lieu of damages. When misappropriation is willful and malicious, the court may award exemplary damages of up to twice the compensatory amount.

Section 30-14-405 provides for attorney fees. The prevailing party may recover fees when a claim or motion was made in bad faith, or when willful and malicious misappropriation is proved.

The limitations period under § 30-14-407 is three years, measured from when the misappropriation was discovered or, through the exercise of reasonable diligence, should have been discovered. Continuing misappropriation constitutes a single claim for limitations purposes, so the clock begins when the first wrongful act was or should have been discovered rather than restarting each time the defendant uses the secret again.

How the federal DTSA applies in Montana

The federal Defend Trade Secrets Act (DTSA), 18 U.S.C. §§ 1836-1839, took effect May 11, 2016, and creates a federal civil cause of 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. Most Montana business information meets this threshold. Because the DTSA does not preempt state law (18 U.S.C. § 1838), Montana claimants routinely plead MUTSA and DTSA claims together in a single lawsuit.

Key DTSA features that supplement Montana state law include:

• Ex parte seizure orders: Federal courts may order the immediate seizure of property to prevent further disclosure or dissemination of a trade secret in extraordinary circumstances (18 U.S.C. § 1836(b)(2)).
• Whistleblower immunity: An individual who discloses a trade secret to a government official or attorney solely to report a suspected legal violation is immune from DTSA civil and criminal liability (18 U.S.C. § 1833(b)).
• Notice requirement: Confidentiality agreements executed or materially updated after May 11, 2016 must include written notice of this whistleblower immunity. Omitting the notice forfeits the right to seek exemplary damages and attorney fees in any DTSA action.
• Three-year federal limitations period: The DTSA carries its own three-year limitations period from discovery (18 U.S.C. § 1836(d)), which aligns with Montana's state-law period, so both claims typically run on the same timeline.

Protecting trade secrets in Montana: practical steps

Under Montana law, reasonable secrecy measures are a definitional prerequisite for trade-secret status, not merely advisable practice. Courts assess whether the holder's protective efforts were proportionate to the value and sensitivity of the information involved.

Recognized protective steps include:

• Written non-disclosure and confidentiality agreements with employees, independent contractors, and third parties that receive access to sensitive business information; agreements executed after May 11, 2016 should include the DTSA whistleblower-immunity notice
• Role-based access controls and encryption protecting digital files, systems, and databases that contain proprietary information
• Physical security measures covering facilities, paper records, and other media holding sensitive material
• Consistent and clear labeling of documents, files, and presentations as confidential or proprietary
• Structured employee offboarding protocols that include revoking system access, recovering company devices, and providing written reminders of continuing confidentiality obligations

Montana courts, like most UTSA jurisdictions, view selective or inconsistent protection unfavorably. Guarding information against some parties while freely sharing it with others can undermine trade-secret status. Well-documented, consistent measures carry more weight than sporadic or retrospective ones.
