The Minnesota Mining and Manufacturing Company (“3M”) produces and markets a product known as carrier tape. When the company discovered that three of its employees had formed Accu-Tech Plastics (“Accu-Tech”) to manufacture and market resin sheeting, the essential component of carrier tape, 3M brought suit. After dismissing certain 3M claims pursuant to Accu-Tech’s summary judgment motion, the case proceeded to trial. The jury ultimately determined that Accu-Tech had misappropriated trade secrets from 3M and that Accu-Tech’s founders had breached duties of loyalty owed to 3M. Following trial, the district court overturned some of the jury’s findings of liability, upheld other findings, and granted 3M’s request for a permanent injunction barring the disclosure (but not the use) of the trade secrets which the jury found Accu-Tech had misappropriated. When final judgment was entered below, the parties filed cross-appeals challenging decisions made by the district court throughout the litigation. For the reasons stated herein, we affirm the district court’s decisions as they pertain to Accu-Tech’s issues on appeal. As for 3M’s claims of error, we affirm in part, and reverse and remand in part the decisions of the district court.
I. BACKGROUND
Since 1986, 3M has manufactured and sold carrier tape through its Surface Mount Supplies Division. Carrier tape, which is used to transport sensitive electronic components, is made principally from a thin layer of plastic called resin sheeting into which pockets are molded to fit the components to be transferred. 3M also manufactures the resin sheeting necessary to produce carrier tape. However, 3M, preferring the higher profit margins that attend to the sale of carrier tape, does not vend resin sheeting in the open market (except to its foreign subsidiaries).
Three individuals who were integral to 3M’s development and production of resin sheeting and carrier tape were Ronald Pri-byl, Thomas Skrtic, and James Harvey. Pribyl, who began working for 3M in 1989 as its Manager of Manufacturing for North America, supervised the production of all of 3M’s resin sheeting and carrier tape in North America. Skrtic, an employee of *593 3M’s Surface Mount Supplies Division from 1986, was the primary developer of 3M’s resin sheeting manufacturing process. Finally, Harvey, who worked as 3M’s quality supervisor, was the principal author of a series of 3M manuals documenting the operating, training, and quality control procedures for producing resin sheeting and carrier tape.
In 1996, 3M announced that it was moving its carrier tape business from Menominee, Wisconsin to Hutchinson, Minnesota. For a variety of reasons, Pribyl, Skrtic, and Harvey did not wish to relocate to Minnesota. Thus, in 1997, the trio, while still under the employ of 3M, formed Accu-Tech. Accu-Tech manufactures and sells resin sheeting to various companies, including those who use the product to manufacture carrier tape. However, Accu-Tech itself does not produce any carrier tape. For approximately two years, Pribyl, Skrtic, and Harvey operated Accu-Tech while still working for 3M. It was not until March of 1999 that their clandestine operation was discovered by 3M. Upon learning of Accu-Tech’s existence, 3M terminated' all three individuals.
On April 23, 1999, 3M brought a diversity suit against Pribyl, Ski-tic, Harvey, and Accu-Tech, in the District Court for the Western District of Wisconsin, 3M asserted a litany of claims against Accu-Tech’s founders, including breach of fiduciary duty, breach of employment contracts, and misappropriation of trade secrets. The complaint also alleged that Accu-Tech, as a corporate entity, had misappropriated trade secrets, engaged in unfair competition, tortiously interfered with prospective contractual relationships, and tortiously induced Skrtic to breach his employment contract with 3M.
Following discovery, the parties filed cross-motions for summary judgment. On November 12, 1999, the district court granted summary judgment in favor of Accu-Tech and its founders on the breach of contract and tortious interference with contract claims. Additionally, the court granted summary judgment to the defendants on the claim for breach of fiduciary duty to the extent that it was based on alleged improper competition with 3M by Accu-Tech’s founders. Finally, the district court held that 3M’s unfair competition claim was indistinguishable from its claims for trade secrets misappropriation and tortious interference with contract. Thereafter, on December 7,1999, the court granted summary judgment in favor of Accu-Tech and its founders on 3M’s claim for tortious interference with prospective contractual relations.
The case proceeded to a bifurcated trial, which commenced on December 13, 1999. On December 16, the jury returned a verdict on liability, finding that: (1) Accu-Tech’s founders had each breached a duty of loyalty to 3M, (2) 3M owned four trade secrets, and (3) Accu-Tech and its founders had misappropriated or threatened to misappropriate two of those four trade secrets. The two trade secrets which the jury determined the defendants had misappropriated were (1) the operating procedures, quality manuals, training manuals, process standards, and operator notes for using plaintiffs equipment that makes resin sheeting (“operating procedures and manuals”), and (2) customized resin formulations that enhance the sheeting and ther-moforming capability of resin and give it properties needed in the electronic industry. 1 The following day, the jury returned *594 its findings on damages. On 3M’s claim for breach of the duty of loyalty, the jury determined that Pribyl was liable in the amount of $126,875, while Harvey and Skrtic each owed 3M $46,000. The jury additionally awarded damages against Accu-Tech and its founders in the amounts of $83,000 for misappropriation of 3M’s trade secret in customized resin formulations and $187,500 for misappropriation of 3M’s trade secret in the operating procedures and manuals.
Shortly thereafter, the defendants filed a motion for judgment as a matter of law or for a new trial. While that motion was pending, 3M moved for the entry of a permanent injunction. On February 9, 2000, the district court partially granted 3M’s motion, permanently enjoining the defendants from disclosing any of the four trade secrets found by the jury, and from using the two trade secrets which the jury had not found use or disclosure of. However, the court denied 3M’s request for a permanent injunction against the use of 3M’s customized resin formulations and operating procedures and manuals.
On March 2, 2000, the district court granted, in part, defendants’ motion for judgment as a matter of law. The court partially overturned the jury’s verdict, ruling that the defendants were not liable for misappropriating 3M’s trade secret in its customized resin formulations. The court also ordered a new trial on the issue of damages for 3M’s breach of loyalty claim, unless 3M accepted a remittitur. Rather than face a new trial on damages, 3M accepted the remittitur. On July 20, 2000, the district court entered its final judgment.
Discontented with various decisions below, the parties have now filed cross-appeals in this court. For their part, defendants argue three points of error. First, they assert that 3M failed to offer any evidence that any specific information within the scope of 3M’s trade secret in the operating procedures and manuals was actually secret to 3M or used or disclosed by the defendants. Thus, defendants argue that the district court erred in not granting them judgment as a matter of law on 3M’s misappropriation claim regarding those items. Secondly, defendants argue that the district court’s order permanently enjoining them from disclosing to any third party 3M’s operating procedures and manuals is overly vague, and thus violates Fed.R.Civ.P. 65(d). Finally, they put forth that the district court erred in admitting excerpts from 3M’s business conduct manual dealing with an employee’s operation of a business that is in competition with any 3M business.
For its part, 3M suggests four points of error. First, 3M argues that the district court erred in granting Accu-Tech summary judgment on 3M’s claim that Accu-Tech had tortiously interfered with defendant Skrtic’s employment contract. Second, 3M contends that the court similarly erred in granting Accu-Tech summary judgment on 3M’s unfair competition claim against the company. Third, 3M asserts that the district court erred in overturning the jury’s finding that the defendants had misappropriated 3M’s trade secret in its customized resin formulations. Finally, 3M claims that the district court erred in denying the company a permanent injunction against defendants’ use of 3M’s trade secrets that the jury found had been misappropriated.
*595 II. DISCUSSION
A. Accu-Tech’s Issues On Appeal
1. Misappropriation of 3M’s Trade Secret
As noted above, the jury determined that 3M had a valid trade secret in its operating procedures and manuals, which in the course of forming and operating Aecu-Tech, the defendants had misappropriated. Appellants’ primary assertion on appeal is that the evidence produced at trial was insufficient to support either of those findings by the jury, and that thus the district court erred in not granting judgment as a matter of law.
Though we review the denial of a motion for judgment as a matter of law
de novo, see Emmel v. Coca-Cola Bottling Co. of Chicago,
According to the Wisconsin Uniform Trade Secrets Act, a trade secret is defined as “information, including a formula, pattern, compilation, program, device, method, technique or process ... [which] 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 which] is the subject of efforts to maintain its secrecy that are reasonable under the circumstances.” Wis. Stat. § 134.90(l)(c);
see also ECT Int’l, Inc. v. Zwerlein,
Throughout the course of their argument, defendants press 3M to divulge what specific information contained within the more than 500 hundred pages of materials could be considered secret. In doing so, defendants seem to suggest that if 3M cannot point to specific items within its manuals that are not known by the industry, then 3M cannot claim a trade secret in the combined product. We disagree. In order to be considered a trade secret, a pattern, technique, or process need not reach the level of invention necessary to warrant patent protection. A trade secret can exist in a combination of characteristics and components, each of which, by
*596
itself, is in the public domain, but the unified process, design and operation of which, in unique combination, affords a competitive advantage and is a protectable secret.
See Syntex Ophthalmias Inc. v. Tsuetaki,
There is no doubt that within the 500-plus pages of manuals at issue, there are a host of materials which would fall within the public domain. For example, 3M’s instructions on how to clean the area around its machines, and how to properly assemble a cardboard box, surely cannot be considered independent trade secrets. Were 3M to bring Accu-Tech to court, claiming misappropriation on ‘the basis that Accu-Tech was assembling ordinary cardboard boxes in a similar manner to 3M, we would not look favorably on such a claim. 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.
Contrary to defendants’ suggestion, 3M is not attempting to preclude Accu-Tech from folding cardboard boxes. Rather, the company is seeking to prevent Accu-Tech from using and disclosing a process which it took the company six years and considerable income to perfect. These manuals and processes, even if comprised solely of materials available in the public domain, have been created by combining those materials into a unified system which is not readily ascertainable by other means. Thus, viewing the evidence in the light most favorable to 3M, we believe there was sufficient evidence to support the jury’s finding that 3M has a trade secret in the operating procedures, quality manuals, trade manuals, process standards and operator notes for using 3M’s equipment that makes resin sheeting.
Turning to the issue of misappropriation, we agree with the district court that there was sufficient evidence to support a powerful inference that defendants used 3M’s operating procedures and manuals in establishing Accu-Tech’s operations. While it took 3M six years and countless resources in order to make its carrier tape operation efficient and profitable, AccuTech was able to almost immediately operate its resin sheeting line effectively. Furthermore, evidence adduced at trial established that there are significant similarities between 3M’s carrier tape line and AccuTech’s resin sheeting line, including the use of the same or similar equipment and materials. Moreover, testimony at trial suggested that Accu-Tech was disclosing to 3M customers and competitors processes detailed in 3M’s manuals. As the district court stated, “[t]he inference is virtually inescapable that defendants gained a significant head start in their operation by using the trade secret knowledge they learned from plaintiff concerning the operation and standards for the line.” We agree that when this evidence, along with all the reasonable inferences that may be drawn from it, is viewed in the light most favorable to 3M, it constitutes sufficient support for the jury’s verdict. As such, we affirm the district court’s denial of AccuTech’s motion for judgment as a matter of law on the issue.
2. Specificity of the Permanent Injunction
On February 9, 2000, the district court partially granted 3M’s request for a permanent injunction. The court ordered that Accu-Tech and its founders were permanently enjoined from disclosing to any third party (1) the operating procedures, quality manuals, process standards, and operator notes for using plaintiffs equipment that makes resin sheeting; (2) plaintiffs customized resin formulations that *597 enhance the sheeting and thermoforming capability of resin and give it properties needed in the electronic industry; (3) plaintiffs slitting technology and experiment results including the design and setup of slitters; and (4) plaintiffs winding methods used to compensate for variations in film calipher. However, contrary to 3M’s request, the district court did not enter an order permanently enjoining the defendants from using 3M’s operating procedures and manuals or customized resin formulation. Rather, the court decreed that once the defendants had paid the plaintiff $270,500 in partial satisfaction of the jury verdict (or provided security in an amount sufficient to assure full payment and subsequent costs), defendants were free to use the two aforementioned trade secrets. 3
On appeal, both parties assert that the district court committed error in its February 9 order. Accu-Tech and its founders, focusing on the court’s injunction against disclosure of 3M’s operating procedures and manuals, contend that the court’s order is too vague, and thus does not comply with Fed.R.Civ.P. 65(d). For its part, 3M maintains that the court incorrectly relied upon defendants’ payment of damages as justification for not permanently enjoining the defendants from using 3M’s misappropriated trade secret — an argument we will address in Part B3. We review the district court’s grant or denial of a permanent injunction for abuse of discretion.
Knapp v. Northwestern Univ.,
The requirements for a valid injunction are found in Fed.R.Civ.P. 65(d), which provides, so far as pertinent here, that “[e]very order granting an injunction ... shall set forth the reasons for its issuance; shall be specific in terms; shall describe in reasonable detail, and not by reference to the complaint or other document, the act or acts sought to be restrained.” As the Supreme Court has noted, “the specificity provisions of Rule 65(d) are no mere technical requirements. The Rule was designed to prevent uncertainty and confusion on the part of those faced with injunctive orders, and to avoid the possible founding of a contempt citation on a decree too vague to be understood.”
Schmidt v. Lessard,
The defendants here contend that the injunction against disclosure entered by the district court must be vacated because, as a matter of law, the terms are too vague to give them fair notice of the prohibited conduct. In so arguing, Accu-Tech and its founders propound that 3M has not identified what information within the 500-plus pages of manuals it considers to be secret, and that much of the information contained in those pages is either generalized business information or information relating to the manufacture of carrier tape, rather than resin sheeting.
The problem of framing an appropriate order may be particularly acute in trade secrets cases,
see id.
at 332, and it for that reason that courts have often set aside trade secrets injunctions as failing to com
*598
ply with Rule 65(d)’s specificity requirements,
see, e.g., E.W. Bliss Co. v. Struthers-Dunn, Inc.,
In this instance, the defendants do not truly find error in the scope of the injunction as protecting disclosure of items beyond that which has previously been determined to be the applicable trade secret. Rather, to the extent that defendants find fault with the district court’s order, it is because they argue that 3M cannot have a valid trade secret in the operating procedures and manuals. We found that argument unpersuasive above, and simply because defendants have refitted it as a challenge to the district court’s permanent injunction does not add any merit to it.
Here, the district court’s order does nothing more than prohibit the defendants from disclosing the trade secret. In its memorandum, the district court acknowledged that defendants had sought a more narrow injunction, identifying specific secrets not to be used. However, the court determined that, in part to curb “the misconduct and evasive action of defendant Pribyl,” no opportunity for loopholes should be allowed. We agree with the district court’s decision that more specificity in the injunction is not mandated. Rule 65(d) does not “require the impossible. There is a limit to what words can convey. The more specific the order, the more opportunities for evasion.”
Scandia Down Corp. v. Euroquilt,
We are aware that certain materials falling within the trade secret are public information. However, we believe it sufficient protection against the fear of unfair surprise embodied in the cases discussing Rule 65(d)’s specificity requirement that injunctions are construed narrowly, with close questions of interpretation being resolved in the defendant’s favor.
See Sobering,
3. Admissibility of Evidence
Subsequent to the conclusion of the liability phase of the trial, the parties debated whether certain exhibits would be provided to the jury to consider during deliberations. Specifically, Accu-Tech and its founders quarreled over two sections of 3M’s business conduct manuals, exhibits 114 and 115, which 3M sought to introduce *599 in support of its breach of loyalty claims. Exhibit 114, entitled “Conflict of Interest Policy” states that “3M employees should not engage in activities that give rise to a conflict of interest or the appearance of a conflict of interest, without prior management approval.” The policy defines a conflict of interest as any activity by a 3M employee that (1) is inconsistent with 3M’s activities or business interests, or (2) could cause a reasonable person to believe that the employee’s judgment might be adversely influenced. Furthermore, the policy provides examples of real and potential conflicts, which include operating a business outside of the employee’s 3M responsibilities which is in conflict with any 3M business. Exhibit 115 likewise lists 3M’s conflict of interest policy, and provides similar language to that contained in exhibit 114. The district court, over defendants’ objection, found that the exhibits were relevant; a decision which Accu-Tech now challenges.
We review a district court’s ruling on the admissibility of evidence for abuse of discretion.
Aetna Life Ins. Co. v. Wise,
Accu-Tech and its founders argüe that the admission of the provisions in 3M’s business conduct manuals regarding operation of a business in competition with 3M constitutes reversible error. Specifically, they asseverate that the admitted portions were inadmissible as irrelevant, see Fed. R.Evid. 401, 402, and as unduly prejudicial and confusing to the jury, see Fed.R.Evid. 403.
In granting the defendants summary judgment on 3M’s claim of breach of loyalty based on improper competition, the district court determined that the defendants did not breach their duty of loyalty with 3M merely by operating Accu-Tech, as Aceu-Tech’s sale of resin sheeting was not in direct competition with 3M’s business (a ruling which 3M disputes). Thus, at trial 3M’s breach of loyalty claim was limited to being predicated upon the misappropriation of 3M’s time and resources by Accu-Tech’s founders in the process of starting Accu-Tech while still working for 3M. Given that the district court did not permit 3M to introduce evidence to the jury suggesting that Accu-Tech had competed with 3M, Accu-Tech asserts that the sections of 3M’s manuals dealing with the operation of a business in competition with 3M were irrelevant. Furthermore, Accu-Tech maintains that the admission of those manuals may have unduly prejudiced or confused the jury into ignoring the relevant standard of law, and instead finding the defendants guilty of breach simply because they had violated 3M’s conflict of interest policy.
We disagree with defendants that the district court erred in admitting 3M’s conflict of interest policies. Certainly, given the court’s decision that Accu-Tech’s *600 founders did not breach a duty of loyalty to 3M by forming their company, the manuals were not relevant (at that juncture) towards proving any theory of liability based on improper competition by the defendants. However, 3M did not offer those manuals in order to prove that Pri-byl, Skrtic, and Harvey had improperly competed with 3M. Rather, the company sought introduction of those materials to assist in proving that Accu-Tech’s founders, who had used 3M’s time and resources, had read 3M’s policies and thus knew that their actions were not permitted. Hence, the introduction of 3M’s manuals was necessary, and therefore relevant, in establishing the mens rea for the plaintiffs remaining breach of loyalty claim.
However, not all relevant evidence is admissible, and we recognize that the jury may have been confused by the conflict of interest standard articulated in 3M’s manuals. In this instance, a strong argument can be made that the probative value of exhibits 114 and 115 was substantially outweighed by the prejudicial effect their admission might have had on the defense. Yet ultimately, Accu-Tech’s Rule 403 argument cannot prevail. In suggesting evidentiary error, the defendants become entrenched in a Catch 22 from which they cannot extricate themselves. The basis for the defendants’ claim here is that the admission of the exhibits was inconsistent with the court’s instruction that the defendants did not breach a duty of loyalty by starting and operating Accu-Tech. However, it is that very instruction which precludes the defendants from establishing that any error actually resulted in harm. This is because, absent evidence to the contrary, we assume that juries follow a court’s instructions.
See United States v. Jones,
B. 3M’s Issues On Appeal
1. Summary Judgment
On November 12,1999, the district court granted summary judgment in favor of the defendants on 3M’s claims that (1) Accu-Tech had tortiously interfered with defendant Skrtic’s employment contract with 3M, and (2) Accu-Tech had engaged in unfair competition with 3M. On appeal, 3M asserts that the district court committed error in granting the defendants summary judgment, and thereby dismissing these counts.
A district court may only grant summary judgment when there are no genuine issues of material fact and the movant is entitled to judgment as a matter of law.
See
Fed.R.Civ.P. 56. We review the district court’s decision on summary judgment
de novo,
viewing all of the facts, and drawing all reasonable inferences from those facts, in favor of the nonmoving party.
See Anderson v. Liberty Lobby, Inc.,
*601 a. Tortious Interference With Skrtic’s Employment Contract
In disposing of 3M’s tortious interference claim, the district court stated that “assuming that Skrtic had breached his employment contract with 3M by his actions in operating Accu-Tech, to suggest that he was induced to do so by the very corporation he created surely cannot follow.” The court noted that Skrtic, as an officer and owner of Accu-Tech, was so intertwined with the company, that “arguing the corporation induced his breach is like arguing that he induced himself to breach.” Relying on the Wisconsin Court of Appeals’ decision in
Wausau Medical Center, S.C. v. Asplund,
3M asserts that the district court’s reliance on Wausau was misplaced. While 3M acknowledges that a party to a contract cannot be held liable for tortiously inducing his or her own breach,
see, e.g., Rao v. Rao,
Whether it is possible for a corporate entity to have tortiously interfered with the employment contract of one of its founders may at times become an interesting inquiry.
4
Tortious interference with a contract occurs when someone intentionally and improperly interferes with the performance of a contract between another and a third person by inducing or otherwise causing the third person not to perform the contract.
See Wausau,
b. Unfair Competition Claim
In its complaint, 3M alleged that Accu-Tech competes with 3M’s products and processes, and that Accu-Tech unfairly competed with 3M by hiring 3M employees with knowledge of confidential information and trade secrets, inducing those employees to breach their employment agreements with 3M and to use 3M’s trade secrets against it. In its November 12 order, the district court granted summary judgment in favor of Accu-Tech, dismissing 3M’s unfair competition claim. According to the district court, because Wisconsin law would not interpret “competition” so broadly as to encompass the relationship between Accu-Tech and 3M, 3M’s unfair competition claim could not be grounded in that theory. After examining other possible bases for the unfair competition claim, the district court determined that “[t]o the extent that there is a claim for unfair competition [the] issues are identical to the trade secret and tortious interference claims.” Thus, the court dismissed the unfair competition claim as being repetitive. On appeal, 3M challenges the decision of the district court. First, it asserts that the issue of competition was inappropriately decided on summary judgment. Second, the company contends that even if its unfair competition claim was duplicative, that is no reason to dismiss the claim at the summary judgment stage.
In determining that 3M and Accu-Tech were not competitors, the district court focused on the fact that 3M did not lose a single sale or customer to Accu-Tech during the course of defendants’ employment with 3M. The court also noted that there existed a market for resin sheeting which Accu-Tech was free to enter into, and which 3M chose not to penetrate. While the court acknowledged that there was some customer overlap between the two companies, the court believed that “the companies were not offering competing products, except in a most indirect sense.”
After reviewing the record in this matter, we conclude that the issue of competition was improperly resolved on summary judgment. The district court, relying on
Zimmermann v. Brennan,
*603 Had the issue of competition been decided by the jury at trial, the evidence relied upon by the district court here would no doubt be sufficient to withstand a motion for judgment as a matter of law. However, we are presented with this issue on appeal from a grant of summary judgment, where we review de novo, viewing the evidence in the light most favorable to 3M, whether there exists a genuine issue of material fact. In such a setting, we must conclude that there is such an issue. As an initial matter, the record contains facts which suggest that these companies were somewhat intertwined. As the court noted, there did exist some customer overlap between 3M and Accu-Tech. As a result of Accu-Tech marketing to 3M customers, companies that required carrier tape were presented with two options: (1) those companies could simply purchase the finished product from 3M, or (2) those companies could purchase resin sheeting from Accu-Tech and process them own carrier tape. Furthermore, 3M presented evidence that Accu-Tech was working in concert with another company which sold machinery to convert resin sheeting into carrier tape, and that Accu-Tech offered its customers advice on how to form pockets in their resin sheeting. Such evidence seems to suggest cross-elasticity of demand, and contradict the finding that these entities were not in competition — thus creating a disputed issue of material fact.
Even assuming that the facts presented by the district court were not in dispute, we do not believe that those facts dictate that Accu-Tech was entitled to judgment as a matter of law.
See
Fed R. Civ. P. 56. For example, we find that whether there are distinct markets for resin sheeting and carrier tape is of little consequence to this competition-determination. While we do not dispute that there may be a submarket for resin sheeting, that does not preclude the fact that resin sheeting may be part of a larger market which includes carrier tape. As the Supreme Court has stated “within [a] broad market, well-defined submarkets may exist which, in themselves, constitute product markets for antitrust purposes.”
Brown Shoe Co. v. United States,
The district court predicated its grant of summary judgment on the duplicative nature of 3M’s unfair competition claim. We have determined that the issue of whether 3M’s carrier tape and Accu-Tech’s resin sheeting are competing products is a disputed factual inquiry, not appropriate for resolution via summary judgment. Thus, the possible competition between Accu-Tech and 3M provides a distinct, independent basis for 3M’s unfair competition claim. Hence, assuming arguendo that it is appropriate to dismiss a cause of action on summary judgment as being duplica-tive — an issue we will not weigh in on— here, there are no duplicative claims which warrant such a dismissal. As such, we must reinstate 3M’s unfair competition claim, and remand the issue to the district court.
2. Misappropriation of 3M’s Customized Resin Formulations
As noted above, the jury concluded that 3M had a trade secret in the “customized resin formulations that enhance the sheeting and thermoforming capability of resin and give it properties needed in the electronic industry.” The jury also determined that the defendants had improperly used or disclosed or threatened to use or disclose that trade secret, and awarded 3M $83,000 in damages. In its motion for judgment as a matter of law, Accu-Tech and its founders renewed an argument that there was no basis for a rational jury to find that the defendants misappropriated any customized resin formulations. The district court, while resolving that the jury had a basis for finding a trade secret in the customized resin formulations, also held that there was no basis for finding misappropriation of any customized resin formulation.
In order to understand the basis for the district court’s finding, a brief explanation of the resin sheeting manufacturing process is necessary. The process for making resin sheeting begins with a raw material called a resin pellet. Resin pellets are widely available in a myriad of different formulations. In perfecting its resin sheeting manufacturing process for making carrier tape, 3M expended significant resources in analyzing and experimenting with different types of resin pellets. Besides using these commercially available resin formulations, 3M independently developed one type of resin formulation — a formula for polystyrene resin. Polystyrene resins are general-purpose, high-impact and ignition-resistant resins that meet application needs across a broad range of market segments including the packing industry. In granting the defendants judgment as a matter of law, the district court determined that the only resin formula which could be considered a customized resin formulation was the polystyrene resin. However, the court noted that while the defendants did use a polystyrene resin for making resin sheeting, they used a commercially available polystyrene resin rather than plaintiffs customized formula. Thus, the court found that there was no rational basis for concluding that Accu-Tech had misappropriated 3M’s customized resin formulation.
We review a district court’s grant of judgment as a matter of law
de novo. See Massey v. Blue Cross-Blue Shield of Ill.,
3M asserts that the district court erred in granting the defendants judgment as a matter of law. First, 3M notes that the defendants were operating Accu-Tech at the time that 3M was developing its polystyrene resin. Because Skrtic was responsible for the manufacturing of the polystyrene resin and admittedly had some knowledge of this customized resin formulation, 3M posits that the district court ignored evidence that permits a reasonable inference that the defendants used 3M’s customized resin formulation. Second, 3M argues that the district court’s decision ignores the fact that the jury’s verdict could have been based on defendants’ threat to use or disclose 3M’s trade secret. Third, 3M suggests that the district court’s decision that there could be no customized resin formulations simply because 3M bought its resin on the open market was in error.
We agree with the district court that no rational juror could have found that defendants used or disclosed 3M’s formula for producing polystyrene resin. There is no dispute that Accu-Tech operated in secret while its founders were employed by 3M. There is also no disagreement that at that time, 3M was developing its own polystyrene resin formula, which Skrtic had some access to. Finally, it cannot be contested that the defendants did in fact use a polystyrene resin formulation in making their resin sheeting. Yet, we cannot draw from these facts a reasonable inference that Accu-Tech was using 3M’s polystyrene resin formulation. First, while he did have access, there is no evidence that proves that Skrtic had knowledge of 3M’s polystyrene resin formula. Furthermore, as the district court noted, the evidence at trial specifically established that Accu-Tech was not using 3M’s polystyrene resin. The testimony presented explicitly revealed that while defendants were engaged in producing resin sheeting from a polystyrene resin, that they used a commercially available resin formula rather than 3M’s customized formula. Against these undisputed facts, 3M’s facts and the reasonable inferences that may be drawn from them do not amount to a scintilla of evidence.
However, 3M is correct to point out that the district court did not address in its grant of judgment as a matter of law whether the defendants had
threatened
to use or disclose 3M’s customized resin formulation. Yet, the district court’s silence on this matter is of little import. While vacating the jury award for misappropriation, the district court left intact a permanent injunction prohibiting the defendants from disclosing 3M’s customized resin formulations. Thus, even assuming that the defendants knew 3M’s customized resin formulations, 3M is sufficiently protected against the threat of disclosure by the district court’s injunction.
See e.g., Pepsi-Co, Inc. v. Redmond,
Finally, we agree with the district court that 3M does not have a claim for misappropriation of a trade secret in customized resin formulations for commercially available resin products. Simply because 3M expended significant-resources in selecting from the market the proper resin formula for making its sheeting does not constitute that selection as a customized resin formulation. As the district court correctly noted, “[t]esting many products on the market to choose the one that meets particular needs does not make that product ‘customized’ in any reasonable sense of the word.” To the extent that 3M now argues that it modifies the commercially purchased resin pellets by blending them in carbon, we find that fact does not assist 3M’s claim. The purpose of blending carbon into a commercially purchased resin is to create a conductive polycarbonate resin. However, testimony at trial revealed that 3M does not make the conductive polycarbonate resin that it uses, but rather that it purchases it from an outside source. More importantly, there is not even a scintilla of evidence to suggest that the defendants misappropriated 3M’s blending method. 5
Overturning a jury verdict is not something that should be done lightly. According to our civil justice system, as enshrined in the Seventh Amendment to the Constitution, the jury is the body best equipped to judge the facts, weigh the evidence, determine credibility, and use its common sense to arrive at a reasoned decision. As a reviewing court, we must be “particularly careful ... to avoid supplanting [our] view of the credibility or the weight of the evidence for that ... of the
*607
jury.”

3. District Court’s Failure to Enjoin Future Use of 3M’s Trade Secrets
Lastly, we return to the district court’s February 9 decision, which partially granted 3M’s request for a permanent injunction. As noted above, the district court, in rendering its decision, relied upon the Fifth Circuit decision in
Next Level Communications LP v. DSC Communications Corporation,
On appeal, 3M contends that the district court’s ruling has
ipso facto
forced the company to sell its trade secrets to those who stole them from it. 3M argues that without an injunction against use, the company is not protected from the future ongoing harm that may be caused by Accu-Tech’s use of 3M’s trade secrets. Further, to the extent that the district court based its decision on
Next Level Communications,
3M asserts that the decision was incorrect. Thus, it requests that we remand this matter and direct the district court to modify the permanent injunction so as to forbid Accu-Tech’s use of 3M’s trade secret. Once again, we review the district court’s grant or denial of a permanent injunction for abuse of discretion, analyzing conclusions of law under a
de novo
standard and "factual determination for clear error.
See Knapp,
The purpose of a permanent injunction is to protect trade secret owners from the ongoing damages caused by the future use of trade secrets, rather than to compensate for those damages.
See Gillen v. City of Neenah,
Yet, in presenting its argument, 3M has overstated the importance of the district court’s analogy to
Next Level Communications,
and understated the factual conclusions which truly propelled the court’s determination. In
Next Level Communications,
the jury had awarded the plaintiff exorbitant damages for lost future profits on sales of switched digital video products containing trade secrets which the defendant had misappropriated.
See
We agree with 3M that the jury’s cost of development award does not render the granting of a permanent injunction against use in this instance as a duplicative remedy. Unfortunately for 3M, the district court did as well. The court’s reference to Next Level Communications was not in-eluded in order to suggest that the payment of any damages for misappropriation gives the misappropriator ownership of the trade secret. 7 In fact, the payment of damages in this instance was largely irrelevant to the court’s decision to deny the injunction against use. The court reliance on Next Level Communications was simply for an unexceptional analogy: that just as a plaintiff who has been compensated for lost future damages should not receive an injunction against permanent use, “[sjimilarly, when a plaintiff has demonstrated no actual damages nor a likelihood of future damages a permanent injunction enjoining use is inappropriate.” In fact, had the court not mentioned Next Level Communications, the assertion that an injunction is inappropriate when there is no likelihood of future harm would have carried no less weight.
It is apparent that the district court’s determination was not based on a legal rule established in the Fifth Circuit. Rather, the court denied 3M the permanent injunction it endeavored because the company had not established the likelihood of any future damages. That is a factual determination which 3M has not sufficiently disputed, and which, under our clearly erroneous standard of review, we cannot find to be in error.
See Knapp,
Yet, the above should not suggest that if monetary damages for lost profits are not sought or quantified, that a permanent injunction against future use cannot be entered. The loss of a trade secret cannot, in some instances, be measured in monetary damages.
See, e.g., FMC Corp. v. Taiwan Tainan Giant Indus. Co., Ltd.,
*609
[t]he right to exclude others is generally one of the most essential sticks in the bundle of rights that are commonly characterized as property [and][w]ith respect to a trade secret ... central to the very definition of the property interest. Once the data that constitute a trade secret are disclosed to others, or others are allowed to use those data, the holder of the trade secret has lost his property interest in the data.
Ruckelshaus v. Monsanto Co.,
Once again, 3M has ignored the factual predicate of the district court’s determination. Instead, 3M suggests that when a party has been found guilty of misappropriation, that party should be enjoined in perpetuity from using the misappropriated trade secret. However, to impose such a draconian rule would be to fundamentally alter the purpose behind the permanent injunction. An injunction is not a punitive tool, but rather a vehicle for preventing injury.
See Gillen,
In this instance, the district court made a factual determination that Accu-Tech would have been able to independently develop 3M’s trade secret in a period of less than two years — a conclusion which 3M does not dispute. Given that Accu-Tech’s founders were the individuals responsible for creating the materials for 3M in the first place, it would be nonsensical to suggest that they would not have been able to duplicate the materials on their own. As such, by the time the district court was faced with determining whether to enjoin Accu-Tech’s use of 3M’s trade secret, the court believed that Accu-Tech would have discovered 3M’s trade secret. Hence, the district court properly determined that once payment to 3M had been made to alleviate any commercial advantage, there would be nothing further gained by enjoining Accu-Tech from using the trade secret which they would have by that time developed. While 3M is correct that Accu-Tech was able to develop its resin sheeting line with more celerity as a result of its misappropriation, we believe, as the district court did, that the jury factored in that monetary benefit in its award to 3M, thereby negating (as best as possible) any commercial advantage which Accu-Tech’s iniquity parented. Giving the appropriate deference to the conclusions of fact made by the district court, we do not believe that the court abused its discretion *610 in not granting 3M a permanent injunction against use. 8
III. CONCLUSION
For the foregoing reasons, we AefiRM the decisions of the district court on all counts, except that we ReveRse and Remand the district court’s grant of summary judgment to Accu-Tech on 3M’s claim for unlawful competition.
Notes
. The jury also determined that 3M had a trade secret in its slitting technology and experiment results including the design and setup of slitters, and in its winding methods used to compensate for variations in film calipher. However, the jury did not find that any of the *594 defendants had improperly used or disclosed, or threatened to use or disclose either of these trade secrets.
. Because the purpose of trade secret law is to encourage innovation and development, protection should not extend beyond the limits needed to protect genuine trade secrets.
See American Can Co. v. Mansukhani,
. As for the plaintiff's trade secrets in slitting technology and winding methods, the district court permanently enjoined the defendants from making use of those secrets.
. While not crucial to the disposition of this matter, we note that under Wisconsin law, the elements of a tortious interference with contract claim are: (1) the plaintiff had a contract or prospective contractual relationship with a third party, (2) the defendant interfered with that relationship, (3) the interference was intentional, (4) a causal connection exists between the interference and the damages, and (5) the defendant was not justified or privileged to interfere.
See Dorr v. Sacred Heart Hosp.,
. 3M urges this Court that the jury’s verdict should not be overturned on insufficiency of evidence grounds, given the fact that the district court determined that the defendants had engaged in spoliation of evidence. At the heart of 3M’s claim lies the fact that the evening before Pribyl was to turn over his computer pursuant to a discovery request, six gigabytes of music was downloaded onto his hard drive. This enormous volume of data consisted of the same songs being recorded multiple times in a short time span. While defendants argued that the spoliation was conducted by Pribyl's children who use the computer, the district court instructed the jury that they could draw a negative inference from the act of destruction. 3M maintains that by overturning the jury verdict on the basis of lack of evidence, the court below negated its instruction and rewarded defendants for their spoliation.
We find the downloading of six gigabytes of music files onto Pribyl’s hard drive on the eve that it was to be turned over for examination troubling, and his proposed justifications difficult to accept. Discovery is a meaningful part of our adversarial system, and were parties to circumvent discovery requests by selectively destroying potentially damaging information, the process would become ineffectual. There is no doubt that the district court was correct in giving a negative inference instruction, and that it could have rightly imposed sanctions on Pribyl. However, the fact that hard drive space was destroyed on Pribyl’s computer does not relieve 3M of having to prove the elements of its claims. 3M has not suggested how the evidence it believed it would have received from the computer would have impacted its misappropriation claim. Without at least some suggestion that the computer contained information which would have assisted 3M’s claim, we cannot allow 3M to prevail on any claim for which there was insufficient evidence. Furthermore, we recognize that the district court was in a unique position to examine the impact that any spoliation may have had on 3M’s claims. The court, while aware of the spoliation, was still comfortable in determining that there was insufficient evidence to support 3M’s claim. Sitting as a court of review, we do not dispute that determination.
. Originally, the district court had not enjoined Accu-Tech from using 3M’s customized resin formulations. However, in light of the district court’s decision on motion for judgment as a matter of law that the defendants had not misappropriated 3M’s trade secret is customized resin formulations, the district court, as part of its April 3 order, added customized resin formulations to the list of trade secrets which Accu-Tech was forbidden to use (as well as disclose). Thus, the only 3M trade secret which Accu-Tech can use as a result of the district court’s orders is the company’s trade secret in the operating procedures and manuals.
. Such a system would encourage parties to bypass the market and misappropriate trade secrets, knowing that if caught, the party would merely have to pay the amount it would have had to negotiate for in the first instance. Though we do not read the decision in Next Level Communications to establish such a regime, to the extent that the opinion can be interpreted to do so, we reject that logic.
. We note in closing that, contrary to 3M's assertion, Accu-Tech, as a result of the district court's decision, has not simply bought the trade secret that it misappropriated. By its malfeasance, Accu-Tech was surely able to acquire 3M’s trade secret with greater rapidity than it otherwise would have. But as a result, not only has Accu-Tech been forced to repay 3M the cost of development, but it has been permanently forbidden from acquiring complete ownership over those trade secrets. Within the bundle of rights commonly characterized as ownership of property also lies the right to transfer ownership. That stick in the bundle is no less essential than the right to exclude others. Yet, as a result of the district court's order, which Accu-Tech has not challenged on appeal, Accu-Tech is forbidden from disclosing 3M's trade secret to any third party, despite the court's finding that the company could have independently developed 3M’s trade secret. Thus, far from leaving 3M with no protection against the future harm caused by Accu-Tech’s misappropriation, the district court's decision has provided 3M with a blanket of protection that it would not have received otherwise.
