Does Idaho have a trade secret law?

Idaho enacted the Idaho Trade Secrets Act in 1981, codified at Idaho Code §§ 48-801 to 48-807. Idaho was among the early states to adopt legislation modeled on the Uniform Trade Secrets Act, providing a consistent civil framework for protecting confidential business information. The Act supplies civil remedies for misappropriation and, under Idaho Code § 48-806, preempts conflicting tort, restitution, and other civil claims based on misappropriation of a trade secret. The preemption provision does not displace criminal statutes, contract claims, or other non-misappropriation causes of action. Because Idaho's definitions and remedies closely track the UTSA, case law from other UTSA states can offer persuasive guidance in Idaho courts.

What counts as a trade secret and misappropriation in Idaho?

Under Idaho Code § 48-801(5), a trade secret is information, including a formula, pattern, compilation, program, computer program, device, method, technique, or process, that satisfies two requirements:

1. It derives independent economic value, actual or potential, from not being generally known to or readily ascertainable by persons who could obtain economic value from its disclosure or use.
2. It is the subject of efforts that are reasonable under the circumstances to maintain its secrecy.

Qualifying examples include customer lists, pricing models, software source code, manufacturing processes, and proprietary research, as long as both prongs are met. Under Idaho Code § 48-801(2), misappropriation includes acquiring another’s trade secret while knowing or having reason to know it was acquired improperly. It also covers disclosure or use without express or implied consent by someone who used improper means, or who at disclosure or use knew or had reason to know the information came through improper means or a source or circumstances imposing a secrecy or limited-use duty. A further branch covers knowledge of a trade secret acquired by accident or mistake before a material change of position. Improper means under § 48-801(1) include theft, bribery, misrepresentation, breach of a duty to maintain secrecy, and industrial espionage. Section 48-801(1) does not expressly mention reverse engineering or independent development. Proper-means acquisition falls outside the improper-acquisition branch of § 48-801(2); independent work that does not acquire, disclose, or use another’s secret does not meet that definition.

Idaho Code § 48-801(4) separately defines computer program as information that can cause a computer to perform logical operations, can be input directly or indirectly, and prominently displays a copyright notice or other proprietary or confidential marking within or on its storage medium, regardless of medium or format. Software owners should account for this statutory marking requirement when evaluating the computer-program category. Section 48-801(5)(b) also makes trade secrets subject to public-agency disclosure according to chapter 1, title 74, Idaho Code; trade-secret status alone does not resolve a public-records request.

Remedies and the limitations period in Idaho

A plaintiff who establishes misappropriation under the Idaho Trade Secrets Act may seek several forms of relief:

• Injunction: Under Idaho Code § 48-802, courts may enjoin actual or threatened misappropriation. In exceptional circumstances a court may condition future use on payment of a reasonable royalty instead of issuing an absolute injunction.
• Damages: Idaho Code § 48-803 authorizes recovery of actual loss caused by misappropriation plus any unjust enrichment not already captured by actual-loss damages. Where damages are difficult to measure, courts may award a reasonable royalty for the period of unauthorized use.
• Exemplary damages: Willful and malicious misappropriation can support an award of up to twice the compensatory damages (Idaho Code § 48-803).
• Attorney fees: The Idaho Trade Secrets Act does not include an attorney's-fees provision for misappropriation claims. Prevailing parties generally bear their own fees absent a separate contractual or statutory basis.

The limitations period is three years (Idaho Code § 48-805). The period begins when the misappropriation was discovered or, through the exercise of reasonable diligence, when it should have been discovered. Continuing misappropriation is treated as a single claim, and the limitations period starts from the first act that was or should have been discovered.

How the federal DTSA applies in Idaho

The Defend Trade Secrets Act, 18 U.S.C. §§ 1836-1839, has offered a federal civil remedy since May 2016 for misappropriation of trade secrets used in, or intended for use in, interstate or foreign commerce. The DTSA does not preempt Idaho law (18 U.S.C. § 1838), so plaintiffs routinely plead both the DTSA and the Idaho Trade Secrets Act in a single action to access federal court while preserving all state remedies.

Key DTSA points for Idaho businesses include:

• A three-year federal limitations period from discovery (18 U.S.C. § 1836(d)), matching Idaho's state period.
• Ex parte seizure of property to prevent propagation of the secret, available in extraordinary circumstances (§ 1836(b)(2)).
• Exemplary damages up to twice for willful and malicious misappropriation, parallel to Idaho's UTSA remedy. The DTSA's attorney-fee award, however, has no state-law equivalent, since Idaho's UTSA does not include a fee-shifting provision.
• Whistleblower immunity: the DTSA protects individuals who disclose trade secrets to government officials or attorneys in connection with reporting a suspected legal violation (§ 1833(b)(1)). Employers must include a notice of this immunity in confidentiality or non-disclosure agreements signed or updated after May 11, 2016 (§ 1833(b)(3)). Omitting the notice forfeits the right to claim exemplary damages and attorney fees under the DTSA.

Federal criminal liability for trade secret theft can also arise under the Economic Espionage Act, 18 U.S.C. §§ 1831-1832.

Frequently Asked Questions

What qualifies as a trade secret under Idaho law?

Under Idaho Code § 48-801(5), information qualifies as a trade secret if it has independent economic value from not being generally known or readily ascertainable by those who could profit from it, and if the owner takes reasonable steps to maintain its secrecy. Formulas, software code, customer lists, pricing data, and manufacturing processes can qualify if the requirements are met. Section 48-801(4) also imposes a prominent copyright or proprietary/confidential marking requirement for its computer-program category, and § 48-801(5)(b) subjects public-agency disclosure to chapter 1, title 74.

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

Idaho Code § 48-805 sets a three-year limitations period. The clock starts when the misappropriation was discovered or, through reasonable diligence, when it should have been discovered. Because continuing misappropriation is treated as a single claim starting from the first discoverable act, waiting to learn more details rarely extends the deadline.

What damages can I recover in an Idaho trade secret case?

A prevailing plaintiff may recover actual losses plus unjust enrichment, or a reasonable royalty in place of those measures. Willful and malicious misappropriation can yield exemplary damages up to twice the compensatory award. Idaho's UTSA does not include an attorney's-fees provision, so fee-shifting generally is not available under state law absent a separate contractual or statutory basis. Courts may also issue injunctions to stop threatened or ongoing misappropriation.

Do non-disclosure agreements and security measures matter in Idaho trade secret cases?

Yes. Reasonable measures to maintain secrecy are a required element of the trade secret definition under Idaho Code § 48-801(5). Non-disclosure agreements, restricted-access controls, password protection, and employee confidentiality training all support the reasonableness showing. Without evidence of protective measures, a court may conclude the information was not a legally protectable trade secret.

Should I plead both the Idaho Trade Secrets Act and the federal DTSA?

In most cases, yes. The DTSA provides access to federal court and its own remedies, including ex parte seizure. The Idaho Trade Secrets Act supplies parallel state remedies, and the DTSA does not preempt Idaho law. Pleading both maximizes available forums and remedies. Consult Idaho counsel to evaluate which venue and claims best suit your facts.
