STEVEN McAULIFFE, District Judge

For approximately seven years, Dr. Doru Caraeni worked at ANSYS, Inc., developing code for software used in computational fluid dynamics ("CFD") simulations. In May of 2009, he resigned his position at ANSYS and went to work for its largest competitor: Computational Dynamics North America ("CDNA"). Three months later, ANSYS filed this suit against CDNA and Caraeni seeking preliminary and permanent injunctive relief, as well as compensatory damages. Specifically, ANSYS's five-count complaint advances the following claims: breach of contract (noncompetition) against Caraeni; breach of contract (non-disclosure) against Caraeni; intentional interference with contractual relations against CDNA; misappropriation of trade secrets against Caraeni and CDNA; and unfair trade practices against CDNA.

Pending before the court is ANSYS's request for preliminary injunctive relief, by which it seeks to enforce the provisions of a one-year covenant not to compete that was part of Caraeni's employment contract with ANSYS. A hearing was held on October 21, 2009, at which the parties appeared and presented evidence and oral argument. For the reasons discussed below, ANSYS's motion for a preliminary injunction is denied.

Standard of Review

I. Injunctive Relief.

"It frequently is observed that a preliminary injunction is an extraordinary and drastic remedy, one that should not be granted unless the movant, by a clear showing, carries the burden of persuasion." Mazurek v. Armstrong, 520 U.S. 968, 972 (1997) (quoting 11A C. Wright, A. Miller, M. Kane, Federal Practice and Procedure § 2948, pp. 129-130 (2d ed. 1995)) (emphasis in original). To obtain a preliminary injunction, ANSYS must establish each of the following: (1) a likelihood of success on the merits of its claims (either at summary judgment or at trial); (2) the potential for irreparable harm if an injunction is not issued; (3) that the hardship imposed upon defendants if they are enjoined will be less than the hardship ANSYS will suffer if no injunction issues; and, finally, (4) that issuance of an injunction is consistent with (or at least not contrary to) the public interest. See Ross-Simons of Warwick, Inc. v. Baccarat, Inc., 102 F.3d 12, 15 (1st Cir. 1996); Douglass v. Londonderry Sch. Bd., 372 F. Supp. 2d 203, 204 (D.N.H. 2005).

II. Covenants Not To Compete.

ANSYS's motion for preliminary injunctive relief is based primarily on its claim that Caraeni breached (and continues to be in breach of) his agreement not to compete with ANSYS. See Plaintiff's memorandum (document no. 2-2) at 2. It adds, however, that it is also entitled to injunctive relief because of Caraeni's alleged violation of both his contractual and statutory obligation not to disclose any of ANSYS's confidential or trade secret information. ANSYS's likelihood of success on the merits, then, turns on its ability to demonstrate: (1) that the covenant not to compete is enforceable against Caraeni under the circumstances presented in this case; and/or (2) that Caraeni has disclosed, or is likely to disclose, confidential and trade secret information he acquired during his employment by ANSYS.

Generally speaking, New Hampshire's public policy discourages covenants not to compete. See Concord Orthopaedics Prof'l Ass'n v. Forbes, 142 N.H. 440, 442 (1997). They are, therefore, narrowly construed. See Merrimack Valley Wood Prods. v. Near, 152 N.H. 192, 197 (2005). Nevertheless, covenants not to compete "are valid and enforceable if the restraint is reasonable, given the particular circumstances of the case." Id.

Whether a covenant not to compete is reasonable is a question for the court to resolve. Concord Orthopaedics, 142 N.H. at 443. For it to be reasonable, a restraint on employment must meet each of the following three criteria: first, it must be no greater than necessary for the protection of the employer's legitimate interest; second, it cannot impose undue hardship on the employee; and, finally, it must not be contrary to the public interest. Id. If a restrictive employment covenant fails to meet any one (or more) of those criteria, it is unenforceable. And, as to the first of those three criteria, the New Hampshire Supreme Court has held:

The first step in determining the reasonableness of a given restraint is to determine whether the restraint was narrowly tailored to protect the employer's legitimate interests. Legitimate interests of an employer that may be protected from competition include: the employer's trade secrets that have been communicated to the employee during the course of employment; confidential information other than trade secrets communicated by the employer to the employee, such as information regarding a unique business method; an employee's special influence over the employer's customers, obtained during the course of employment; contacts developed during the employment; and the employer's development of goodwill and a positive image.
ACAS Acquisitions (Precitech), Inc. v. Hobert, 155 N.H. 381, 389 (2007) (citations omitted).

In this case, ANSYS says it is concerned that Caraeni might share with his new employer — CDNA — confidential and/or trade secret information acquired during the course of his employment at ANSYS. It is not enough, however, for ANSYS merely to have a generalized or abstract concern that its confidential and/or trade secret information might be compromised because a former employee now works for a competitor. Instead, as the party seeking to enforce the covenant not to compete, ANSYS must show that there is a reasonable basis to believe that Caraeni might actually use or share that confidential and/or trade secret information for the benefit of CDNA. See id. at 392. See also Kelly Services, Inc. v. Greene, 535 F. Supp. 2d 180, 185-86, 188 (D. Me. 2008) (concluding that plaintiff did not show a likelihood of success on the merits, given its failure to "allege any specific acts of actual or threatened misappropriation [of trade secrets or confidential information]").

Factual Background

At the evidentiary hearing, defendants called Dr. Wayne Smith, the General Manager of CDNA, and Dr. Doru Caraeni. ANSYS called Dr. Nelson Carter. Based upon the testimony of those witnesses, as well as the record evidence, the court makes the following findings of fact.

ANSYS and CDNA produce and sell competing CFD software products. Essentially, it appears that each product employs mathematical principles and algorithms to model fluid and gas flows in various environments and over different complex surfaces. Together, the two companies account for roughly 80 percent of the worldwide market share in this highly specialized and advanced field.

At a very general level, the CFD software products sold by ANSYS and CDNA function (and are created) fairly similarly. First, publicly disclosed mathematical algorithms (i.e., algorithms published in scholarly journals) are reviewed and selected for potential use in the company's product. Then, software code is written so that a chosen algorithm can be "tweaked" or modified as necessary to fit into the product. And, through a process of trial and error, that code is further refined to make it more efficient — that is, to make it solve problems presented more quickly and/or more accurately.

Although ANSYS and CDNA are competitors, the companies do have certain connections dating back several years. Beginning in the late 1980's, Dr. Smith worked for ANSYS's predecessor (Fluent, Inc.) and helped develop an "unstructured solution adaptive parallel CFD software product." Smith Affidavit (document no. 13-3) at para. 3. That software formed the foundation of FLUENT 4 and was incorporated into later versions of FLUENT, including the product currently sold by ANSYS as FLUENT 12. According to Smith, the "ANSYS code that [currently] competes in the market against [CDNA's CFD software] is the code that [he] began work on in 1987. Although the ANSYS code has been revised and supplemented, it has not been fundamentally changed since it was originally introduced." Id. at para. 20.

In 2006, ANSYS purchased Fluent, Inc. For the sake of simplicity, the court will refer to those companies simply as "ANSYS."

In October of 1999, ANSYS and Dr. Smith parted ways over strategic development, and perhaps other disagreements. CDNA promptly hired Dr. Smith to develop that company's next generation CFD software product. Shortly thereafter, Smith hired three more former ANSYS employees and began working on CDNA's next generation CFD software. According to Smith, the resulting software was the product of more than five years of research and planning, was written in a different programming language than the ANSYS product (C++ and JAVA, rather than C and Lisp), and it was based upon an entirely different architecture than the ANSYS product. Smith Affidavit, at para. 13. Although Smith contributed significantly to the architecture and code of the ANSYS product, not a single line of code from that product was used in the CDNA product — at least in part because the programs are written in different languages, they have entirely different architectures, and they adopt different approaches to solving problems and simulating fluid flows. Nevertheless, ANSYS sued Smith and the three other former ANSYS employees, alleging that they had misappropriated ANSYS's trade secrets. Fluent Holdings, Inc. v. Computational Dynamics North Am., Ltd., No. 00-E-057 (Grafton Sup. Ct. 2000) ("ANSYS I"). It is unclear how that dispute was ultimately resolved, but the record does reveal that ANSYS was denied the preliminary injunctive relief it sought.

II. Dr. Doru Caraeni's Covenant Not to Compete.

In 2002, Dr. Caraeni was hired by ANSYS's predecessor (Fluent) to develop code for existing, as well as next generation, CFD software. As a condition of his employment, Caraeni signed an "Employee Confidentiality, Non-Disclosure, and Non-Competition Agreement" (the "Covenant not to Compete"). Complaint, Exhibit I (document no. 1-10). In it, Caraeni acknowledged that he understood:

that computer programs (source code, object code and code portions), programs and system documentation, manuals, engineering drawings, plans, specifications, program capabilities, algorithms, methods and other similar materials are developed at significant expense by Fluent, or in some cases, entrusted to Fluent by its clients and business partners. In some cases all or portions of this information is subject to greater than routine efforts by Fluent to maintain such materials as secret, which secrets may be identified as such by written or printed legends or other means. Other information may be subject to lesser protective efforts, but are nevertheless confidential, such as, for example, the identities of Fluent's customers, suppliers, consultants, marketing plans, development plans, and information concerning the nature or direction of research and development efforts. All of the foregoing shall constitute Confidential Information.
Id. at 1. Caraeni agreed that he would not disclose any Confidential Information and, "for a period of one (1) year following termination of [his] employment with Fluent, [he would] not become an employee, director, consultant, or in any way engage in or contribute [his] knowledge to a competitor of Fluent within North America or within countries where Fluent has subsidiary corporations." Id. at 2. In 2006, after ANSYS acquired Fluent, Caraeni executed an amendment to his Covenant not to Compete, in which he agreed to be bound by the same terms and conditions during the course of his employment by ANSYS (and for one year following termination of that employment). See Complaint, Exhibit K (document no. 1-12).

III. ANSYS's Claims Against Caraeni and CDNA.

In simple terms, ANSYS is concerned that Dr. Caraeni will share its confidential and/or trade secret information (e.g., programming "tweaks" or "tricks" applied to the code so it and/or the publicly-known algorithms run more efficiently) with his new employer, CDNA. CDNA says that is not possible. First, it claims that because it and ANSYS are the two major players in this highly technical field, it is not unusual for employees to move between the two companies; if they wish to stay in this field, they have very few other employment opportunities. Accordingly, CDNA says it has adopted (and enforces) a strict policy which prevents its employees from using any confidential or trade secret information of a competitor.

Moreover, says CDNA, even if Dr. Caraeni wanted to use ANSYS's confidential or trade secret information and tried to incorporate it into CDNA's software, he could not. Although, at least on a superficial level, the competing products sold by ANSYS and CDNA are created similarly and function to solve similar problems, they are built on very different software platforms or, as the witnesses testified, "architectures." Because those architectures are so different, it would not be possible for Caraeni to, for example, simply copy software code from the ANSYS product into the CDNA product. And, says CDNA, it would be equally impossible for Caraeni to employ any of the techniques he might have learned or developed while at ANSYS for incorporating various algorithms into the source code. The same is true, says CDNA, with respect to any of the coding "tweaks" that Caraeni might have learned to make the ANSYS software more efficient. By way of analogy, CDNA suggests that all the confidential information and/or trade secrets that Caraeni might have acquired from ANSYS is akin to information concerning the design, construction, and refining of an internal combustion engine. At CDNA, however, he is working on an electric motor, so none of the solutions, skills, tricks, tweaks, or innovations that he might have learned or developed for, say, improving the fuel efficiency of a four-stroke engine can be translated to his current work.

ANSYS disagrees, claiming that much of the confidential and trade secret information Dr. Caraeni acquired while in its employ could be used to enhance and refine the CDNA product. So, for example, in his affidavit, Dr. Thomas Tysinger, testified that:

While ANSYS does not claim that known theories are confidential, all of the new and unique solutions in Tap and Flux are proprietary and confidential. Dr. Caraeni himself created such information, and therefore has intimate knowledge of it. While ANSYS understands that Dr. Caraeni could not simply cut-and-paste the TAP and Flux code into STAR-CCM+ [CDNA's CFD product], he can use his knowledge of how he implemented functionality in TAP to implement the same or similar functionality in STAR-CCM+. Even if STAR-CCM+ already contains the same or similar functionality as TAP and Flux, Dr. Caraeni could use his knowledge to improve corresponding functionality in STAR-CCM+.

Tysinger Affidavit (document no. 24) at para. 10. See also Hearing Testimony of Dr. Nelson Carter, at pages 111-17.


I. Likelihood of Success on the Merits.

The parties' factual disagreement over whether ANSYS's trade secrets and/or confidential information can be applied to CDNA's code is a significant dispute in this case. At this juncture, it remains unresolved. ANSYS has not persuaded the court that Caraeni's work for CDNA poses a genuine risk that its trade secrets or confidential information will be disclosed for the benefit of CDNA.

Accordingly, based upon the record currently before the court, it cannot conclude that ANSYS has carried its burden to demonstrate that it is likely to succeed on the merits of its claims. Even assuming that the covenant not to compete's geographic scope (worldwide) and temporal limitation (one-year) are sufficiently narrowly-tailored under the circumstances, ANSYS has failed to demonstrate that there is a reasonable possibility that Caraeni will disclose confidential and/or trade secret information during the course of his employment by CDNA.

As was the case in the parties' earlier state court litigation, ANSYS has not clearly identified the trade secrets it believes Caraeni and/or CDNA might appropriate. Nor has it clearly distinguished between those alleged trade secrets and Caraeni's general knowledge of mathematics, physics, and computer programming — information not subject to trade secret protection. As the state court pointedly observed:

[ANSYS] failed to meet its burden to establish the existence of a trade secret or secrets. Exhibit 8 and the testimony presented at the hearing by petitioner's employees fails to establish with any degree of specificity the trade secrets ANSYS seeks to protect. Witnesses for the petitioner continuously made reference to the "tricks" that the programmers used to make the general concepts part of the software code. Respondents denied knowledge of any "tricks." It is conceivable that "tricks" could be entitled to protection. Nonetheless, based upon the facts presented, the Court is unable to parse the "tricks" from the experience and skill of the programmers.
ANSYS I, Order denying preliminary injunctive relief (N.H. Sup. Ct. May 5, 2000) (citations omitted).

For the same reasons that ANSYS has failed to demonstrate a likelihood of success on the merits of its breach of contract claims (i.e., non-disclosure and covenant not to compete), it has also failed to show a likelihood of success on its statutory claim that Caraeni and/or CDNA have misappropriated its trade secrets.

II. Irreparable Injury.

Moreover, even if it had shown that Caraeni possesses some of its confidential or trade secret information, ANSYS has failed to demonstrate that he is likely to use that information during the course of his employment at CDNA. Although the court lacks the comprehensive understanding of the mathematics, fluid dynamics, and computer programming necessary to fully understand the parties' competing software products, it does find credible the testimony of Dr. Smith. Crediting that testimony as true (at least for purposes of resolving ANSYS's pending motion), the court is compelled to conclude that ANSYS has not shown the potential for irreparable injury in the absence of injunctive relief.

Presumably, at trial the parties will present testimony of independent experts regarding the various principles of mathematics and physics that must be understood in order to fully comprehend the nature of ANSYS's claims and defendants' defenses.

First, Smith credibly testified that CDNA maintains and enforces a strict policy preventing its employees from using confidential and trade secret information they may have acquired from prior employers. See, e.g., Hearing testimony of Wayne Smith, Ph.D. (Oct. 21, 2009), at pages 45 and 66. See generally Kelly Services, 535 F. Supp. 2d at 188-89 ("Kelly Services' claim that it will suffer irreparable harm simply as a result of Greene working for Maine Staffing is also unpersuasive. The affidavits submitted by Greene and Mark Burns show that Greene can be employed by Maine Staffing without disclosing or using any protected information of Kelly Services.") (citation omitted).

References to the transcript of the hearing are to a rough, unedited transcript prepared by the stenographer. If an official transcript is prepared, page references may be slightly different.

The court also finds credible Dr. Smith's testimony that Dr. Caraeni has not been assigned (and, in the near-term is not expected to be assigned) to perform any work at CDNA that might allow him to use any of ANSYS's confidential or trade secret information. Additionally, given the fact that CDNA's and ANSYS's products are built upon different architectures, the court credits Dr. Smith's testimony that any confidential or trade secret information that Caraeni might have acquired from ANSYS simply would not usefully translate to work performed on CDNA's CFD software.

[Dr. Doru Caraeni's] work to date at CDNA has not involved the areas in which he worked at ANSYS. ANSYS claims that Doru's work for CDNA "will entail researching and developing code for high-speed flow." This is incorrect; he has not done any work for CDNA in this area. No matter what the field of work to which he is assigned, I am confident that he can do the work without using or disclosing to CDNA personnel any Fluent or ANSYS trade secrets. The CDNA code uses an entirely different architecture than the Fluent code (since I wrote both, I can state with certainty the extent of the difference), and the material in the current ANSYS code simply would not assist us in the least in our work on STAR-CCM+ code. Even if the new work at ANSYS on Flux or the work on TAP or NCS is interesting and cutting edge, there is no reason to expect that it would assist CDNA in the least and, more important, CDNA has an unbending policy against the use of confidential information. We have followed that policy to the letter.

Smith Affidavit at para. 38.

Crediting that testimony as true, the court concludes that ANSYS has failed to demonstrate that it will suffer irreparable injury in the absence of injunctive relief.


Having concluded that ANSYS has failed to demonstrate either a likelihood of success on the merits of its claims or irreparable injury in the absence of the injunction it seeks, ANSYS is not entitled to a preliminary injunction. Accordingly, plaintiff's motion for preliminary injunction (document no. 2) is denied. It's motion to strike (document no. 27) is likewise denied, in light of defendants' responsive pleading and additional submissions.
