Trade Secret Misappropriation Remedies in Minnesota

What remedies does Minnesota law give a trade secret owner?

MUTSA authorizes an injunction against actual or threatened misappropriation, a royalty in place of a ban in exceptional cases, court-ordered protective acts, damages, exemplary damages for willful and malicious misappropriation, and attorney fees. The DTSA mirrors each of these and adds ex parte seizure.

The Minnesota menu sits in three sections:

1. Injunctions. “Actual or threatened misappropriation may be enjoined.” (Minn. Stat. § 325C.02, para. (a).) The same section allows a royalty-conditioned injunction (para. (b)) and an order compelling “affirmative acts to protect a trade secret” (para. (c)).
2. Damages. Actual loss plus unjust enrichment not already counted in actual loss, or a reasonable royalty in place of those measures. (Minn. Stat. § 325C.03, para. (a).) For willful and malicious misappropriation, “the court may award exemplary damages in an amount not exceeding twice any award made under paragraph (a).” (Para. (b).)
3. Attorney fees. The court may award reasonable attorney fees for a bad-faith claim, a motion to terminate an injunction that is made or resisted in bad faith, or willful and malicious misappropriation. (Minn. Stat. § 325C.04.)

The federal list in 18 U.S.C. § 1836(b)(3) tracks these closely, with exemplary damages capped at “not more than 2 times” the compensatory award. The sections below take each remedy in turn: what it requires and when it is worth asking for.

What must you prove before any remedy is available?

Every remedy requires two things: information that qualifies as a trade secret, and misappropriation of it. Bad conduct alone is not enough. The Minnesota Supreme Court put it plainly: “Without a proven trade secret there can be no action for misappropriation, even if defendants’ actions were wrongful.”

That sentence comes from Electro-Craft Corp. v. Controlled Motion, Inc., 332 N.W.2d 890 (Minn. 1983), where the court reversed a misappropriation judgment because the company had not proven a protectable secret. Under Minn. Stat. § 325C.01, subd. 5, 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,” and must be “the subject of efforts that are reasonable under the circumstances to maintain its secrecy.” The details of what counts as a trade secret under Minnesota law and the secrecy measures a court expects to see decide many cases before remedies are reached.

Misappropriation is the second element. Under subd. 3, it includes “acquisition of a trade secret of another by a person who knows or has reason to know that the trade secret was acquired by improper means,” and “disclosure or use of a trade secret of another without express or implied consent” by a person who used improper means or knew or had reason to know of the problem. “Improper means” includes “theft, bribery, misrepresentation, breach or inducement of a breach of a duty to maintain secrecy, or espionage through electronic or other means” (subd. 2). Taking alone can qualify; you do not have to wait for proof of use.

How does a trade secret injunction work in Minnesota?

A Minnesota court can enjoin misappropriation that is threatened as well as actual. On application to the court, the injunction is terminated when the secret ceases to exist, and the court may continue it for an additional reasonable period to eliminate the defendant’s commercial advantage.

Duration is set by statute: “Upon application to the court, an injunction shall be terminated when the trade secret has ceased to exist, but the injunction may be continued for an additional reasonable period of time in order to eliminate commercial advantage that otherwise would be derived from the misappropriation.” (Minn. Stat. § 325C.02, para. (a).) An injunction is the remedy to choose when continued use would do harm that money cannot repair, such as a competitor bidding your customers with your pricing.

An injunction also demands precision. In Electro-Craft, the court found that, “given ECC’s lack of specificity, it was impossible for the district court to fashion a meaningful injunction which would not overly restrict legitimate competition.” Before you ask, I suggest writing down exactly which files, formulas, or lists are the secret, because the order can only protect what you can name.

Scope has limits in Minnesota. “Any covenant not to compete contained in a contract or agreement is void and unenforceable” (Minn. Stat. § 181.988, subd. 2(a)), although the ban does not reach “a nondisclosure agreement, or agreement designed to protect trade secrets or confidential information,” or “a nonsolicitation agreement, or agreement restricting the ability to use client or contact lists, or solicit customers of the employer” (subd. 1(a)). The ban “applies to contracts and agreements entered into on or after” July 1, 2023 (2023 Minn. Laws ch. 53, art. 6, sec. 1), and a covenant not to compete remains “valid and enforceable” if it “is agreed upon during the sale of a business” or “in anticipation of the dissolution of a business” (Minn. Stat. § 181.988, subd. 2(b)). On the federal side, a DTSA injunction may not “prevent a person from entering into an employment relationship,” and conditions on that employment must be “based on evidence of threatened misappropriation and not merely on the information the person knows” (18 U.S.C. § 1836(b)(3)(A)(i)). The procedure for getting the order quickly, including the bond, is covered in how a Minnesota trade secret case moves from a TRO to a temporary injunction.

When can a court let the defendant keep using the secret for a royalty?

Only “in exceptional circumstances.” A Minnesota court may then let the defendant continue using the secret on payment of a reasonable royalty, typically where the defendant changed position in good faith before learning of the misappropriation and a ban would be unfair.

The statute reads: “In exceptional circumstances, an injunction may condition future use upon payment of a reasonable royalty for no longer than the period of time for which use could have been prohibited.” Its example is “a material and prejudicial change of position prior to acquiring knowledge or reason to know of misappropriation that renders a prohibitive injunction inequitable.” (Minn. Stat. § 325C.02, para. (b).) A buyer that built a production line around a process before learning it was stolen fits that example.

The same idea limits money. Damages are recoverable “except to the extent that a material and prejudicial change of position prior to acquiring knowledge or reason to know of misappropriation renders a monetary recovery inequitable.” (Minn. Stat. § 325C.03, para. (a).) The DTSA has a parallel royalty injunction in 18 U.S.C. § 1836(b)(3)(A)(iii). For an owner, the practical lesson is timing: putting an innocent user on notice early limits how much change of position it can later claim.

What can a court order a defendant to do to protect the secret?

Beyond forbidding use, a Minnesota court can order the defendant to take steps that protect the secret. The statute says “in appropriate circumstances, affirmative acts to protect a trade secret may be compelled by court order.”

That sentence is Minn. Stat. § 325C.02, para. (c), and the DTSA has a matching provision in § 1836(b)(3)(A)(ii). The statute does not list the acts. Owners typically ask for the return of documents and devices, deletion of copies from personal accounts, and a sworn statement or forensic check confirming the deletion. When the secret sits on a former employee’s laptop or cloud drive, getting it back can matter more than any damages figure, and it is often the first relief to request after taking the first steps after a former employee takes your information.

Court orders carry teeth. In Electro-Craft, the defendant kept selling products after a temporary injunction, and the court affirmed a contempt finding: “Its decision to violate the injunction instead of seeking its modification demonstrated disrespect for an order of a court of this state, and the district court properly held CMI in contempt.”

When is a federal ex parte seizure worth asking for?

Rarely. A federal court may order seizure without notice “only in extraordinary circumstances,” and only on specific findings that include that an ordinary injunction would be evaded and that the defendant would hide or destroy the material if warned. MUTSA has no counterpart.

Under 18 U.S.C. § 1836(b)(2), the court “may, upon ex parte application but only in extraordinary circumstances, issue an order providing for the seizure of property necessary to prevent the propagation or dissemination of the trade secret.” The court may not grant it unless it finds, among other things, that a Rule 65 order “would be inadequate . . . because the party to which the order would be issued would evade, avoid, or otherwise not comply with such an order,” and that the target “would destroy, move, hide, or otherwise make such matter inaccessible to the court, if the applicant were to proceed on notice.”

The risk runs back to the applicant. The order must “require the person obtaining the order to provide the security determined adequate by the court,” and “a person who suffers damage by reason of a wrongful or excessive seizure under this paragraph has a cause of action against the applicant.” Seizure fits the defendant with a record of ignoring orders or preparing to leave the country. For an ordinary departing employee, an order to return and stop using the material, which can still be sought on short notice, is usually the better tool.

How do you choose among actual loss, unjust enrichment, and a reasonable royalty?

You pick the damages measure your evidence supports. Minnesota allows actual loss plus any unjust enrichment not already counted, or, as an alternative, a reasonable royalty for the defendant’s unauthorized use.

The text: “Damages can include both the actual loss caused by misappropriation and the unjust enrichment caused by misappropriation that is not taken into account in computing actual loss. In lieu of damages measured by any other methods, the damages caused by misappropriation may be measured by imposition of liability for a reasonable royalty for a misappropriator’s unauthorized disclosure or use of a trade secret.” (Minn. Stat. § 325C.03, para. (a).)

In practice the choice runs like this:

• Actual loss fits when you can trace lost sales or customers to the misappropriation.
• Unjust enrichment adds the defendant’s gain that your loss does not capture, such as development costs it saved by copying, but never double-counts the same dollars.
• A reasonable royalty fits when use is clear but your loss is hard to prove; it replaces the other measures rather than adding to them.

Proof of lost profits is its own subject, covered with the litigation steps in the TRO and temporary-injunction guide linked above.

What turns a damages claim into exemplary damages and attorney fees?

A finding of willful and malicious misappropriation. With it, a Minnesota court may add exemplary damages of up to twice the compensatory award and may award attorney fees. Both are discretionary, and fees can also run against an owner who sues in bad faith.

For willful and malicious misappropriation, exemplary damages are capped at “an amount not exceeding twice any award made under paragraph (a)” (Minn. Stat. § 325C.03, para. (b)). Fees are available “if (i) a claim of misappropriation is made in bad faith, (ii) a motion to terminate an injunction is made or resisted in bad faith, or (iii) willful and malicious misappropriation exists,” and the award is “reasonable attorney’s fees to the prevailing party” (Minn. Stat. § 325C.04). The fee provision cuts both ways: an owner that files a weak claim to pressure a competitor risks paying the competitor’s fees.

The DTSA adds a condition that catches many employers. An employer “shall provide notice of the immunity set forth in this subsection in any contract or agreement with an employee that governs the use of a trade secret or other confidential information,” and an employer that does not “may not be awarded exemplary damages or attorney fees” under the DTSA “in an action against an employee to whom notice was not provided” (18 U.S.C. § 1833(b)(3)). That paragraph “shall apply to contracts and agreements that are entered into or updated after the date of enactment of this subsection” (§ 1833(b)(3)(D)). The notice rule reaches contractors and consultants too: “For purposes of this subsection, the term “employee” includes any individual performing work as a contractor or consultant for an employer” (18 U.S.C. § 1833(b)(4)). Reviewing your forms against confidentiality agreements that hold up in Minnesota before a dispute keeps these remedies open.

How should a business match the remedy to its goal?

Start with what you most need, then pick the remedy that delivers it with the proof you have. Most owners want the use stopped first and the money second, and a single lawsuit can seek both.

• Stop the use now: an injunction under § 325C.02(a), sought on an emergency basis, with the secret named precisely; on application, it is terminated when the secret ceases to exist, and the court may continue it for an additional reasonable period to eliminate the commercial advantage.
• Get the copies back: an order compelling protective acts under § 325C.02(c); a federal seizure only with evidence the defendant would evade an order or destroy the material.
• Be paid for the harm: the damages measure your evidence supports under § 325C.03(a): actual loss and unjust enrichment, or a reasonable royalty.
• Deter and recover fees: exemplary damages and fees, which require proof of willful and malicious conduct and, under the DTSA, the § 1833(b) notice in any agreement with an employee, a term that includes a contractor or consultant (see the exemplary-damages section above), entered into or updated after the date of enactment of that subsection.
• Keep the contract claim: MUTSA displaces “conflicting tort, restitutionary, and other law of this state providing civil remedies for misappropriation of a trade secret,” but not “contractual remedies, whether or not based upon misappropriation of a trade secret” (Minn. Stat. § 325C.07), so a breach claim on a confidentiality agreement stays available.

Forum is a separate choice. The DTSA applies when the secret “is related to a product or service used in, or intended for use in, interstate or foreign commerce” (18 U.S.C. § 1836(b)(1)), and it does not “preempt or displace any other remedies” under state law (18 U.S.C. § 1838), so both claims can be filed together. The considerations are laid out in when a federal Defend Trade Secrets Act claim is the better fit. Timing applies to every option: MUTSA sets a filing deadline that runs from when the misappropriation “is discovered or by the exercise of reasonable diligence should have been discovered” (Minn. Stat. § 325C.06), and the DTSA sets its own deadline, also running from when the misappropriation “is discovered or by the exercise of reasonable diligence should have been discovered” (18 U.S.C. § 1836(d)), so check the current text of both as soon as you suspect a theft.

Choosing a trade secret remedy in Minnesota comes down to three questions: can you prove a trade secret and its misappropriation, what do you most need from the court, and what evidence supports each remedy. An injunction and a protective-acts order address the harm still to come; damages, exemplary damages, and fees address the harm already done; and the DTSA adds a federal forum and, in rare cases, seizure.
