  • 2006-07-13 In Burbank Grease Services, LLC v. Sokolowski, the Wisconsin Supreme Court reversed the Court of Appeals and held that § 134.90(6) leaves civil remedies available for misuse of confidential information that is not a statutory trade secret. Source

What qualifies as a trade secret

Section 134.90 treats whether information is generally known or readily ascertainable by proper means as relevant to trade secret status, and comparable competitor information can be circumstantial evidence on that issue.

Nalco Chemical Co. v. Hydro Technologies, Inc. · filed 1993-04-08(1)(c)1.

In my opinion, under both Wis.Stat. § 134.90 and the first factor of the Restatement test, evidence of the types of competitor information in Nalco’s control is relevant to the critical issue of deciding whether the defendants possess Nalco trade secrets—a factor in deciding the larger question of whether the defendants misappropriated Nalco trade secrets. If Nalco possesses information on its competitors, “generally known” in the water treatment industry and obtained by “proper means,” and that information is similar to such competitor information properly acquired by the defendants about Nalco, then such competitor information retained by Nalco would be probative circumstantial evidence useful to the defendants at trial.

Section 134.90(1)(c) allows a unified compilation of publicly known elements to qualify as a trade secret if it meets the other statutory requirements.

Minnesota Mining & Manufacturing Company v. Ronald Pribyl, James Harvey, Thomas Skrtic, and Accu-Tech Plastics, Incorpor · filed 2001-08-20(1)(c)

Yet, when all the cleaning procedures, temperature settings, safety protocols, and equipment calibrations are collected and set out as a unified process, that compilation, if it meets the other qualifications, may be considered a trade secret.

Section 134.90 supplies the governing standard for deciding whether a customer list is a trade secret; the earlier Restatement-based test does not control.

American National Property & Casualty Co. v. Graham · filed 2005-05-19

But that was before Wisconsin adopted the Uniform Trade Secrets Act, which has a set of criteria different from the Restatement of Torts for determining whether something is a trade secret. Wis. Stat. § 134.90.

A process described only in general terms will usually be widely known and thus fail to qualify as a trade secret; the claimant must identify the protected details.

Bondpro Corporation v. Siemens Power Generation, Inc. · filed 2006-09-12(1)(c)(1)

One expects a trade secret to be rich in detail, because a process described in general terms, (squeeze insulation materials draped on the male mold with heat and air pressure rather than pressing the male mold into a female mold containing the materials) will usually be widely known and thus not worth incurring costs to try to conceal and so not a trade secret.

Information is not a trade secret under § 134.90 merely because it is commercially valuable; its secrecy must give it independent economic value.

Forst v. SmithKline Beecham Corp. · filed 2009-03-11(1)(c)

As described by the Wisconsin Trade Secrets Act, “trade secret” means any information that: 1) 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 2) is the subject of efforts that are reasonable under the circumstances to maintain its secrecy. Wis. Stat. § 134.90. ... Further, after reviewing the subject documents, the court does not independently conclude that the information derives independent economic value from remaining unknown, or that competitors could obtain economic value from its disclosure.

Section 134.90 can protect a unified manufacturing process as a trade secret even when individual components are not secret.

Centrifugal Acquisition Corp. v. Moon · filed 2012-02-02(1)(c)

Balestrieri’s attempt to divide various aspects of the Proprietary Process into “secret” and “non-secret” categories does not undermine the status of the entire, unified process as a trade secret.

A claimant under § 134.90 must identify the alleged trade secret with enough specificity to show that particular information meets the statutory definition.

Kuryakyn Holdings, LLC v. Ciro, LLC · filed 2017-03-15(1)(c)

Defendants’ criticism reveals a larger problem with Kuryakyn’s claims: Kuryakyn offers vague, generalized descriptions of its purported trade secrets without demonstrating that any specific piece of information meets the statutory definition of trade.secret.

Customer information readily ascertainable from a phone book or by asking at a business is not a trade secret under § 134.90(1)(c).

That being the case, the customer information that is the subject of the confidentiality covenant would not constitute a trade secret.

Both conditions are satisfied. ... In any event, the customer information in the database is a trade secret.

Information that can be determined without undue experimentation under patent law is not necessarily readily ascertainable under the trade secret definition in § 134.90.

Metso Minerals Industries, Inc. v. FLSmidth-Excel LLC · filed 2010-05-13(1)(c)

For defendants to prevail under this line of reasoning, the court would have to hold that if Metso’s dimensions and tolerances are able to be determined without “undue experimentation” then they must be “readily ascertainable.” However, given the difference in the two standards, the court has no basis for making such a finding.

Section 134.90(1)(c) allows a compilation of otherwise public data to qualify as a trade secret.

Section 134.90(1)(c) requires a claimant to identify information that qualifies as a trade secret to show a likelihood of success on a misappropriation claim.

PFS Investments Inc. v. Thompson, Timothy · filed 2023-03-02(1)(c)

As the court discussed with the parties during the preliminary injunction hearing, Primerica has not shown a likelihood of success on its misappropriation of trade secrets claim, having failed to identify any information that Thompson took from Primerica that would qualify as a trade secret under Wisconsin or federal law. See 18 U.S.C. § 1839(3) (federal definition of “trade secret”); Wis. Stat. § 134.90(1)(c) (Wisconsin definition of “trade secret”).

Section 134.90(1)(c) requires information to derive independent economic value from secrecy and to be subject to reasonable efforts to maintain its secrecy to qualify as a trade secret.

Norwood · filed 2026-01-06(1)(c)

Wisconsin statutes define “trade secret” as “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” and “is the subject of efforts to maintain its secrecy that are reasonable under the circumstances.” Wis. Stat. §134.90(1)(c). The amended complaint contains no allegations that the Blowout Feature is a trade secret or that it has been subject of efforts to maintain its secrecy. The amended complaint does not state a claim for unjust enrichment or trade secret misappropriation under Wisconsin law.

Retaining customer names and contact information alone does not constitute trade secret misappropriation under § 134.90 when that information is readily ascertainable.

Allstate Insurance Company v. Deanna Freeman · filed 2026-01-07(1)(c)

Customer names and contact information on their own are readily ascertainable, so retaining this type of information wouldn’t amount to misappropriation of trade secrets.

Reasonable efforts to maintain secrecy

Section 134.90(1)(c) does not protect information freely given to anyone who requests it because that information is not subject to efforts to maintain its secrecy.

Nalco Chemical Co. v. Hydro Technologies, Inc. · filed 1993-07-16(1)(c)

The Nalco product bulletins at issue are indisputably freely given to any person who requests such information from Nalco. Thus, product bulletins are not trade secrets because the information contained in them is not “subject of efforts to maintain its secrecy.”

Section 134.90(1)(c) requires reasonable efforts to keep information secret; ordinary facility access restrictions and passwords alone do not establish those efforts.

Maxpower Corp. v. Abraham · filed 2008-04-29(1)(c)

It is not enough simply to restrict access to the facility and require passwords; these are normal business practices in any business. An employer must use additional measures to protect the confidentiality of information he considers to be a trade secret.

Section 134.90(1)(c)(2) requires reasonable efforts to keep information secret; an assumed confidential relationship does not establish reasonable efforts when the owner takes no affirmative precautions.

Fail-Safe LLC v. A.O. Smith Corp. · filed 2010-09-03(1)(c)(2)

Here, the court concludes that, even assuming that the parties had a relationship with implications that the information shared between the parties would be confidential, the undisputed evidence, even when construed most favorably toward the plaintiff, does not indicate that FS took reasonable precautions with respect to its proprietary information.

Section 134.90 requires reasonable efforts under the circumstances to keep information secret; taking no protective steps defeats trade secret protection.

Fail-Safe, LLC v. A.O. Smith Corp. · filed 2012-03-29(1)(c)2.

FS failed to take reasonable protective measures for its claimed trade secret under the circumstances, and thus cannot claim trade secret protection. To qualify as a trade secret under Wisconsin law, the claimed trade secret—that is, the proprietary information—must be the “subject of efforts to maintain its secrecy that are reasonable under the circumstances.” Wis. Stat. § 134.90 (2011).

Section 134.90(2) permits a duty to keep information confidential to arise from an implicit agreement, but minority shareholder status alone does not establish that duty.

Starsurgical Inc. v. Aperta, LLC · filed 2014-08-14(2)

Although Wittmann’s role as minority shareholder did not ipso facto create a duty of confidentiality, taking the facts in the light most favorable to Star, a reasonable jury could find an implicit agreement between the Wittmanns and Star to keep the financial data and the FDA approval information confidential.

Section 134.90(1)(c) allows custom designs and pricing to qualify as trade secrets when their owner takes reasonable steps to keep them secret.

Even absent waiver of this argument, Pioneer presented sufficient evidence from which the jury could reasonably conclude that Pioneer took steps to maintain the secrecy of its custom designs and pricing that were reasonable under the circumstances.

Identifying and proving a trade secret

A plaintiff seeking preliminary relief under § 134.90 must present meaningful evidence that the information at issue qualifies as a trade secret.

Nalco Chemical Co. v. Hydro Technologies, Inc. · filed 1992-05-07(1)(c)

Nalco Chemical failed to adduce any meaningful evidence demonstrating the existence of any of trade secrets under the protection of the Uniform Trade Secret Act, Wis.Stat. § 134.90 (defining “trade secret” as, among other things, information that obtains some independent economic value from not being generally known to others).

Section 134.90 requires a claimant to identify the specific means claimed as trade secrets when those means provide product features also found in competing products; listing the features alone is insufficient.

IDX Systems Corp. v. Epic Systems Corp. · filed 2001-07-31(1)(c)

Listing product functionalities as trade secret areas is insufficient, particularly here, where it is conceded that the functionalities are not trade secrets and exist in competing products. Where plaintiff seeks to protect as trade secrets specific means of providing common features those specific means must be identified.

Section 134.90 does not require a plaintiff to identify the specific information constituting a trade secret at the pleading stage, although that specificity is required to prevail.

Community Hospital Partners, LLC v. Marshfield Clinic Health System, Inc. · filed 2023-03-09

To prevail on its claim, CHP will be required to identify the specific information it contends is a trade secret. But that specificity isn’t required at the pleading stage.

Section 134.90 permits a trade secret claim when the plaintiff alleges misappropriation of valuable information that is not generally known or readily ascertainable and that the plaintiff took reasonable steps to protect.

Kunes Country Automotive Management Inc v. Walters · filed 2024-05-10(1)(c)

Plaintiffs have alleged that Defendants misappropriated valuable information that was not generally known or readily ascertainable that Plaintiffs took reasonable steps to protect. That is sufficient to state a claim under Section 134.90.

Misappropriation and duty of confidentiality

Section 134.90(2)(a) covers breach of an implied promise to use a client’s trade secrets solely for the client’s benefit; an express written confidentiality agreement is unnecessary.

Finally, under Wis. Stat. § 134.90, trade secret misappropriation can occur when a person knows or has reason to know his or her actions are improper. Wis. Stat. § 134.90(2)(a), (b)2. The statute does not require actual knowledge or intent.

Section 134.90(2) does not require proof of monetary damages to establish a trade secret misappropriation claim.

DF Institute, LLC v. Dalton Education, LLC · filed 2020-08-11(2)

Proof of monetary damages isn’t an element of a trade secrets misappropriation claim. As discussed above, a trade secrets claim has two elements: (1) the defendant acquired, used, or disclosed the plaintiff’s information through improper means; and (2) the information at issue qualifies as a trade secret. 18 U.S.C. § 1639(5); Wis. Stat. § 134.90(2). So the court cannot grant summary judgment to Dalton simply because Kaplan can’t prove damages.

Injunctive relief

A party seeking a preliminary injunction for trade secret misappropriation must clearly identify and make a prima facie showing of its proprietary rights, even when disclosure could cause serious harm.

Automated's argument that it will be seriously harmed if Sharp discloses Automated's trade secrets is inherently true in any trade secret case. That does not, however, relieve a party from clearly identifying and prima facie proving its proprietary rights to obtain a preliminary injunction.

Cargill Incorporated v. Bingenheimer · filed 2020-03-19(3)(b)-(c), (4)

Bingenheimer also argues that because he returned all of Cargill’s information, Cargill has no additional remedy under the relevant trade secret statutes. This is incorrect; Cargill could still be granted further injunctive relief and damages. See 18 U.S.C. § 1836(b)(3) (remedies); Wis Stat. § 134.90(3)(b)-(c) (prospective injunctive relief); Wis Stat. § 134.90(4) (damages).

Damages

Section 134.90(4)(b) leaves punitive damages for willful and malicious trade secret misappropriation to the court’s discretion, so omitting a jury instruction on willfulness is harmless when the court would not award punitive damages.

Sokol Crystal Products, Inc. v. Dsc Communications Corporation, F/k/a Digital Switch Corporation, Cross-Appellee · filed 1994-02-09(4)(b)

But the statute says that if a misappropriation is willful and malicious, “the court may award punitive damages” (emphasis supplied). The district court, in refusing a willfulness instruction, said that there is “nothing in the record to demonstrate that the act was malicious.” R.O.A. 211:181. It is therefore clear that the court would not have awarded punitive damages, and thus that failing to give the instruction (even if it was error) was not prejudicial.

Displacement of other claims

Section 134.90(6)(a) does not displace a tort claim for inducing breach of a nondisclosure agreement because enforcing the agreement does not conflict with trade-secret law.

Idx Systems Corporation v. Epic Systems Corporation, University of Wisconsin Medical Foundation, Mitchell Quade, and Mic · filed 2002-04-01(6)(a)

Enforcement of a non-disclosure agreement does not conflict with trade-secret law, and thus preventing third parties from inducing breach of such an agreement does not conflict with trade-secret law.

Section 134.90(6)(a) displaces an unjust enrichment claim only if the claim is based on information that qualifies as a statutory trade secret; whether it does can require factual development.

Genzyme Corp. v. Bishop · filed 2006-12-01(6)(a)

At this stage, the Court does not possess sufficient factual information to conclude as a matter of law that the allegedly received and retained information (which serves as the factual basis for count two of plaintiffs amended complaint) constitutes a trade secret.
