Arizona's trade secret statute, the Arizona Uniform Trade Secrets Act, is codified at Ariz. Rev. Stat. §§ 44-401 to 44-407 (enacted 1990) and follows the Uniform Trade Secrets Act model. The civil limitations period is three years from discovery of the misappropriation.
This guide is part of our Trade Secret Laws by State series.
Information last verified on 2026-06-25. This article presents general legal information, not legal advice. This guide covers civil trade-secret protection in Arizona under Ariz. Rev. Stat. §§ 44-401 to 44-407 and the federal DTSA; for other jurisdictions see the full Trade Secret Laws by State index.
Does Arizona have a trade secret law?
Yes. Arizona enacted the Arizona Uniform Trade Secrets Act in 1990, codified at Ariz. Rev. Stat. §§ 44-401 to 44-407 (Arizona State Legislature, azleg.gov). The statute is modeled on the Uniform Trade Secrets Act published by the Uniform Law Commission and provides a civil cause of action for misappropriation of qualifying confidential business information. Arizona's law displaces conflicting civil claims based on the same misappropriation conduct (Ariz. Rev. Stat. § 44-407), but preserves contract remedies, criminal liability, and civil claims not grounded in misappropriation. The federal Defend Trade Secrets Act (DTSA), 18 U.S.C. §§ 1836-1839 (2016), also applies when an Arizona trade secret relates to a product or service used in or intended for use in interstate or foreign commerce. Federal law does not preempt Arizona's statute (18 U.S.C. § 1838), so state and federal claims may proceed together in a single action.
What counts as a trade secret and misappropriation in Arizona?
Under Ariz. Rev. Stat. § 44-401(4), a trade secret is information, including a formula, pattern, compilation, program, device, method, technique, or process, that:
- Derives 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; and
- Is the subject of efforts that are reasonable under the circumstances to maintain its secrecy.
Both prongs must be satisfied. Arizona courts evaluate whether the owner took concrete protective steps: non-disclosure agreements, access controls, confidentiality policies, and security measures all support the reasonable-measures element. Information disclosed without restrictions or that appears in publicly accessible sources generally cannot qualify.
Misappropriation under Ariz. Rev. Stat. § 44-401(2) means either: (a) acquisition of a trade secret by a person who knows or has reason to know it was acquired by improper means; or (b) disclosure or use of a trade secret without consent by a person who acquired it through improper means, who breached a duty of confidentiality, or who derived it from someone who did so.
Lawful reverse engineering and independent development generally do not establish misappropriation when they involve no improper acquisition, use, or breach of confidentiality. Ariz. Rev. Stat. § 44-401(1) defines improper means but does not expressly name these practices. A competitor who independently arrives at the same formula, process, or design without using the plaintiff's protected information has not committed misappropriation under Arizona law.
Remedies and the limitations period in Arizona
Limitations period: Ariz. Rev. Stat. § 44-406 sets a three-year limitations period from the date the misappropriation was discovered, or by the exercise of reasonable diligence should have been discovered. Continuing misappropriation constitutes a single claim, with the period beginning at the time of the first act the owner knew or should have known about. Arizona's three-year window matches the UTSA model and the federal DTSA period.
Injunctive relief: Under Ariz. Rev. Stat. § 44-402, courts may enjoin actual or threatened misappropriation. On application, an injunction must terminate when the trade secret ceases to exist, but may continue for an additional reasonable period to eliminate the commercial advantage from misappropriation. In exceptional circumstances, an injunction may condition future use on a reasonable royalty for no longer than the period the use could have been prohibited. Section 44-402(B) gives as an example a material, prejudicial change of position before knowledge or reason to know of misappropriation that makes a prohibitive injunction inequitable.
Damages: Ariz. Rev. Stat. § 44-403(A) permits recovery of actual loss caused by the misappropriation plus unjust enrichment not already captured in the actual-loss calculation. Instead of damages measured by other methods, a court may measure damages by a reasonable royalty for unauthorized disclosure or use.
Exemplary damages: For willful and malicious misappropriation, Arizona courts may award exemplary damages in an amount not exceeding twice the compensatory damages under Ariz. Rev. Stat. § 44-403(B).
Attorney fees: Ariz. Rev. Stat. § 44-404 permits 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 willful and malicious misappropriation.
How the federal DTSA applies in Arizona
The DTSA (18 U.S.C. §§ 1836-1839) took effect May 11, 2016, and provides a federal civil remedy when an Arizona trade secret relates to a product or service used in or intended for use in interstate or foreign commerce. Arizona's active technology, semiconductor, real estate, agriculture, and healthcare industries mean most commercial trade secret disputes will support a concurrent DTSA claim alongside the state cause of action.
Key DTSA features relevant to Arizona businesses:
- Aligned limitations period: The DTSA's three-year window from discovery (18 U.S.C. § 1836(d)) matches Arizona's period under Ariz. Rev. Stat. § 44-406, so a plaintiff who files within the state deadline is also timely under federal law.
- Ex parte seizure: The DTSA allows courts to order seizure of property to prevent propagation of the secret without advance notice to the defendant in extraordinary circumstances (18 U.S.C. § 1836(b)(2)). Arizona's state statute has no equivalent provision.
- Comparable remedies: DTSA remedies (injunction, damages, exemplary up to 2x, attorney fees for willful and malicious) parallel Arizona's state remedies and apply under federal standards.
- Whistleblower immunity and notice: Under 18 U.S.C. § 1833(b), an individual may disclose a trade secret in confidence to a government official or attorney for the purpose of reporting a suspected legal violation without civil or criminal liability. Employers must include written notice of this immunity in any agreement governing the use of a trade secret, including NDAs and employment agreements, signed or updated after May 11, 2016. Omitting this notice forfeits the right to seek exemplary damages and attorney fees in a DTSA action against the person covered by that agreement.
Arizona technology and manufacturing companies in particular should review post-2016 confidentiality and employment agreements to confirm DTSA-compliant whistleblower language is present in each document.

Frequently Asked Questions
How long do I have to file a trade secret lawsuit in Arizona?
Ariz. Rev. Stat. § 44-406 provides three years from the date the misappropriation was discovered or, by the exercise of reasonable diligence, should have been discovered. Continuing misappropriation is treated as a single claim, with the limitations period beginning at the first act the owner knew or should have known about. The federal DTSA also provides a three-year window from discovery (18 U.S.C. § 1836(d)), consistent with Arizona's state deadline.
What types of information can be protected as trade secrets in Arizona?
Under Ariz. Rev. Stat. § 44-401(4), any formula, pattern, compilation, program, device, method, technique, or process can qualify if it meets both prongs of the trade-secret test. Customer lists, software source code, proprietary semiconductor manufacturing processes, agricultural formulas, pricing strategies, and business plans are common examples. Both economic value from secrecy and reasonable protective measures must be present; information shared without restrictions or available publicly generally will not qualify.
Can an Arizona employer sue a former employee for using trade secrets at a new company?
Yes. If a former employee uses or discloses protectable Arizona trade secrets in breach of a confidentiality agreement or another duty of secrecy, the employer may bring a claim under Ariz. Rev. Stat. §§ 44-401 to 44-407. General skills, industry knowledge, and experience developed during employment are not trade secrets and cannot be restricted. The boundary between protectable confidential information and general employee know-how is often disputed and depends heavily on the specific facts.
Is reverse engineering legal under Arizona trade secret law?
Generally, yes, where there is no improper acquisition, use, or breach of confidentiality. Ariz. Rev. Stat. § 44-401(1) defines improper means but does not expressly name reverse engineering or independent development. Analyzing a lawfully obtained product without improper acquisition, use, or breach of a duty of confidentiality does not itself establish misappropriation. Protection applies only against acquisition or use through improper means such as theft, bribery, misrepresentation, espionage, or breach of a duty of confidentiality.
What civil claims does Arizona's trade secret law preempt?
Ariz. Rev. Stat. § 44-407 displaces conflicting civil claims based on the same conduct that constitutes trade secret misappropriation under Arizona law. Tort claims such as unfair competition or unjust enrichment premised on misappropriation are subsumed by the statutory cause of action. The preemption clause does not affect contract remedies, criminal liability, or civil claims not grounded in trade secret misappropriation. Federal DTSA claims are also unaffected.
