IN THE UNITED STATES DISTRICT COURT
FOR THE EASTERN DISTRICT OF PENNSYLVANIA
CONTOUR DATA SOLUTIONS LLC
Plaintiff,
v. CIVIL ACTION NO. 20-3241
GRIDFORCE ENERGY
MANAGEMENT LLC, et al.
Defendants.
MEMORANDUM OPINION
Rufe, J. August 23, 2024
Plaintiff Contour Data Solutions, LLC brings this action against Gridforce Energy
Management LLC and NAES Corporation (together, “Gridforce”) for breach of contract,
conversion and/or negligent destruction of property, state and federal trade secret
misappropriation, and violations of the Federal Computer Fraud and Abuse Act (“CFAA”), the
Federal Stored Communications Act (“SCA”), and the Texas Harmful Access by a Computer
Act (“THACA”). Gridforce has asserted a counterclaim for breach of contract. Gridforce seeks
to exclude the opinions of Contour’s experts James Joseph (“J.T.”) Thompson, the former
President of Gridforce, and William Brian Bohn, Chief Architect at Clearpath Solutions Group.1
For the reasons set forth below, both motions will be granted.
1 See Gridforce’s Mot. Exclude Bohn [Doc. No. 338]; Defs.’ Mot. Exclude Thompson [Doc. No. 342]. Gridforce has
adopted the briefings of former Defendants CDW Corporation and CDW Direct LLC, who are no longer parties.
See Gridforce’s Notice [Doc. No. 391].
I. BACKGROUND
This case arises from a contractual dispute over the ownership and use of an Information
Technology System (“IT System”) that Contour set up for Gridforce to run its business.2 Contour
is a technology company in the Delaware Valley region which provides various technology
services, including information technology and cloud-based network operating support.3 Contour
works with each of its clients to identify their goals, technology integration issues, and problem
areas to develop an IT strategy and system.4 Gridforce is a power services company that provides
energy control and integration management services to balance and route electricity throughout
North America.5
On June 27, 2014, Gridforce and Contour entered into a Managed Master Services
Agreement (“MMSA”) outlining the parties’ obligations for the IT System at issue in this case.6
The MMSA was signed by Thompson in Texas on June 25, 2014, and then by Rocco Guerriero,
the founder of Contour, in Pennsylvania on June 27, 2014. The MMSA provided for an initial
36-month term, with an annual 12-month renewal unless terminated with written notice not less
than 180 days before the expiration of the Initial Term or any Renewal Term.7 The MMSA
governed Contour’s design, construction, and maintenance of Gridforce’s IT System, as well as
the parties’ rights and responsibilities concerning the IT System.8 Contour was tasked with

judgment motion. See Gridforce’s Resp. Contour’s Statement of Facts [Doc. No. 358-1]. The Court therefore
provides a cursory outline of the facts, which will be supplemented in the discussion section.

server virtualization, i.e., converting Gridforce’s physical servers into a cloud-based virtual
environment through the use of virtual machines.9 Server virtualization allows virtual servers to
perform specific tasks within the IT environment.10 Contour asserts that Gridforce stole its IT
System, which it claims is a trade secret, and then transitioned the system to another provider.
II. LEGAL STANDARD
Rule 702 of the Federal Rules of Evidence governs the admissibility of expert testimony
and provides that:
[a] witness who is qualified as an expert by knowledge, skill, experience, training,
or education may testify in the form of an opinion or otherwise if the proponent
demonstrates to the court that it is more likely than not that:
(a) the expert’s scientific, technical, or other specialized knowledge will help
the trier of fact to understand the evidence or to determine a fact in issue;
(b) the testimony is based on sufficient facts or data;
(c) the testimony is the product of reliable principles and methods; and
(d) the expert’s opinion reflects a reliable application of the principles and
methods to the facts of the case.11
The focus of the Court’s inquiry must be on the expert’s methods, not the expert’s
conclusions. The Third Circuit has interpreted Rule 702 as setting forth three requirements:
(1) the expert must be qualified; (2) the expert must testify about matters requiring scientific,
technical, or specialized knowledge; and (3) the expert’s testimony must assist the trier of fact.12
“The proponent of the expert testimony bears the burden to show by a preponderance of the
9 A virtual machine is a software program which emulates a physical computer or mimics a physical server or
physical hardware. An operating system and applications can then be installed onto the virtual machine. A virtual
machine can be created and run from a computer or deployed from a cloud-based environment. Once a virtual
machine is created, an operating system and applications, such as email, phone, and file servers, may be installed on
it and it can be deployed into a specific IT environment. See Contour Data Sols. LLC v. Gridforce Energy Mgmt.

evidence that their expert’s opinion is reliable.”13 District courts have “broad discretion in
determining the admissibility of evidence, and ‘considerable leeway’ in determining the
reliability of particular expert testimony . . . .”14
Under the first requirement, “a broad range of knowledge, skills, and training qualify an
expert as such.”15 However, courts have rejected the idea that witnesses offered as experts must
meet “overly rigorous requirements of expertise,” so long as they have “more generalized
qualifications.”16 Under the second requirement, “an expert’s testimony is admissible so long as
the process or technique the expert used in formulating the opinion is reliable.”17 An expert’s
opinion is reliable if it is “based on the ‘methods and procedures of science’ rather than on
‘subjective belief or unsupported speculation . . . .’”18 The experts must have good grounds for
their opinions, but not necessarily the best grounds or unflawed methods.19 Under the third
requirement—whether the expert’s testimony will assist the trier of fact—“the Court must
determine the ‘fit’ of the expert’s testimony as it relates to the case at hand . . . .”20 The fit
requirement “goes primarily to relevance.”21

III. DISCUSSION
a. J.T. Thompson
J.T. Thompson, the former President of Gridforce, negotiated the MMSA on Gridforce’s
behalf and was terminated from Gridforce in December 2015.22 He has now provided an expert
opinion for Contour, opining on the independent economic value (“IEV”) of the IT System.23
Gridforce moves to exclude Thompson’s testimony under Rule 702 because it is unreliable.
Specifically, Gridforce argues that Thompson did not review the IT System or any documents in
forming his opinion,24 and he fails to articulate how the IT System functions or how it is
different from other IT systems used by Gridforce’s competitors.
In the Third Circuit, “an expert’s testimony is admissible so long as the process or
technique the expert used in formulating the opinion is reliable.”25 District courts consider
several factors in determining reliability, including:
22 Hyla Decl., Ex. 1., Thompson Dep. Tr. [Doc. No. 347] at 102–03.
23 See Hyla Decl., Ex. 3, Thompson Report [Doc. No. 347]. Contour bring multiple misappropriation of trade secret
claims. To prove misappropriation, Contour must establish “(1) the existence of a trade secret; (2) communication of
the trade secret pursuant to a confidential relationship; (3) use of the trade secret, in violation of that confidence; and
(4) harm to the plaintiff.” Ecosave Automation, Inc. v. Del. Valley Automation, LLC, No. 20-5564, 540 F. Supp. 3d
491, 500 (E.D. Pa. 2021) (citations omitted) (discussing elements of the Pennsylvania Uniform Trade Secrets Act
(“PUTSA”)). A trade secret is defined under the relevant statutes as “information, including a formula, pattern,
compilation, program, device, method, technique, or process” that “hold[s] independent economic value because it is
not generally known to or readily ascertainable by others who stand to benefit economically if they use or disclose
it, and . . . [is] the subject of reasonable efforts to maintain its secrecy.” LeJeune v. Coin Acceptors, Inc., 849 A.2d
451, 462 (Md. 2004) (quotation marks and citations omitted) (discussing Maryland Uniform Trade Secrets Act); see
also Teva Pharms. USA, Inc. v. Sandhu, 291 F. Supp 3d 659, 675 (E.D. Pa. 2018) (discussing Defend Trade Secrets
Act, 18 U.S.C. § 1839(3), and PUTSA, 12 Pa. Cons. Stat. § 5302). Therefore, the determination of whether the
IT System has independent economic value is essential to the federal and state misappropriation claims.
24 Thompson states in his Report that his opinions are based on his “personal knowledge, [his] technical, specialized
and professional education, experience, expertise and knowledge and upon facts provided to [him].” See Hyla Decl.,
Ex. 3, Thompson Report [Doc. No. 347] at 10.
25 Paoli, 35 F.3d at 742.
(1) whether a method consists of a testable hypothesis; (2) whether the method
has been subject to peer review; (3) the known or potential rate of error; (4) the
existence and maintenance of standards controlling the technique’s operation;
(5) whether the method is generally accepted; (6) the relationship of the technique
to methods which have been established to be reliable; (7) the qualifications of the
expert witness testifying based on the methodology; and (8) the non-judicial uses
to which the method has been put.26
Contour has failed to meet its burden of establishing that Thompson’s opinions are
reliable.27 A careful review of Thompson’s expert report reveals that his opinions are based on
his “subjective belief” rather than the “methods and procedures of science.”28 “[I]t is impossible
to test a hypothesis generated by a subjective methodology because the only person capable of
testing or falsifying the hypothesis is the creator of the methodology.”29
Contour argues that Thompson’s opinion is based on his personal knowledge, 22 years of
experience in creating and operating balancing authority services like Gridforce, and 30 years of
experience as a power services executive.30 However, Thompson does not set forth any
established method for evaluating whether the IT System has IEV or constitutes a trade secret.
Contour’s hyperbolic statement that Thompson is “probably the best person in the world to
opine”31 on the IEV of the IT System is of little value when his conclusion is premised merely on
his own companies’ decisions to license the IT System, rather than on any technical
knowledge.32 This type of testimony cannot be properly tested through cross-examination.33

Expert testimony must also “fit the issues in the case,” i.e., “the expert’s testimony must
be relevant for the purposes of the case and must assist the trier of fact.”34 One of the
fundamental issues in this case is whether the IT System derives IEV from its secrecy.35
Thompson, however, opines only on the general value of the IT System—namely, his view that
the IT System has value because certain unidentified companies in the industry might be willing
to pay to use it—and not whether it derives value from its secrecy. Therefore, his testimony does
not “fit” the case. While Thompson may very well be a useful fact witness at trial, the Court will
exclude Thompson’s expert opinion on the basis of lack of reliability and fit under Rule 702.36
b. William Brian Bohn
William Brian Bohn, Contour’s IT expert, is a Chief Architect at Clearpath Solutions
Group. Bohn has submitted two expert reports dated October 15, 2021 (the “First Bohn
Report”)37 and April 12, 2022 (the “Second Bohn Report”).38 The Second Bohn Report consists
of three sections. The first section sets forth Bohn’s opinion on the hacking claims. The second
section is titled “Content of Contour IT System – Stolen in Violation of Anti-Hacking Statutes –
relying solely or primarily on experience, then the witness must explain how that experience leads to the conclusion
reached, why that experience is a sufficient basis for the opinion, and how that experience is reliably applied to the
facts.”); Player v. Motiva Enters., LLC, 240 F. App’x 513, 520 (3d Cir. 2007) (“The District Court certainly had the
discretion to exclude ‘opinion evidence that is connected to existing data only by the ipse dixit of the expert.’”

36 Gridforce also argues that Thompson’s opinion should be excluded because he has (or had) a financial interest in
the outcome of the case. The Court need not determine whether Thompson’s alleged financial interest constitutes a
conflict warranting exclusion, given that his opinion is subject to exclusion under Rule 702.

94 Virtual Machines (VM’s).” The third section provides rebuttal opinions regarding Gridforce
and CDW’s expert witnesses.
Gridforce moves to exclude Bohn’s opinions under Rule 702.39 Gridforce argues that:
(1) Bohn’s IEV opinions are unreliable; (2) Bohn’s opinions on 70 pages of settings are
unreliable; (3) Bohn’s opinions that Gridforce took the IT System are unreliable; and (4) Bohn’s
conclusion that the IT System is an electronic communication is a legal conclusion and therefore
inadmissible. The Court discusses each argument in turn.
1. Bohn’s IEV Opinions
Gridforce contends that Bohn’s opinion on the IEV of the IT System is unreliable. To be
considered a trade secret, the IT System must “derive[ ] independent economic value, actual or
potential, from not being generally known to, and not being readily ascertainable through proper
means by, another person who can obtain economic value from the disclosure or use of the
information[.]”40 Therefore, an expert opinion on the IEV of the IT System is directly relevant to
Contour’s misappropriation of trade secret claims.
In the First Bohn Report, Bohn opines that the IT System “is a compilation of
information . . . created solely by Contour that is (a) not generally known to other persons who
can obtain economic value from its disclosure and use, (b) not readily ascertainable by proper
39 Gridforce also moves to strike sections two and three of the Second Bohn Report based on untimeliness.
However, the Court allowed additional reports to be filed, and Gridforce has failed to establish prejudice. Gridforce
was provided with the opportunity to depose Bohn after the Second Bohn Report. See Cochran v. Jackson,
No. 14-2165, 2015 WL 3555291, at *4 (E.D. Pa. June 8, 2015) (holding that prejudice caused by an untimely report
could be cured by allowing plaintiff the opportunity to depose defendant’s expert prior to trial); Macaluso, 2023 WL
4685965, at *7 (declining to exclude an opinion on the basis that it was untimely because defendant failed to explain
how it would be prejudiced by a revision in the opinion, particularly when no trial date certain was fast
approaching). Further, it appears that Gridforce’s experts had access to the same information as Bohn, and that the
Second Bohn Report does not necessarily include any new or supplemental opinions (except the opinions on the
computer hacking claims). Therefore, the Court declines to exclude the Second Bohn Report based on untimeliness.
40 Oakwood Laboratories LLC v. Thanoo, 999 F.3d 892, 905 (3d Cir. 2021) (quoting 18 U.S.C. § 1839(3)).
means by any such persons and (c) derives independent economic value from (a) and (b).”41 In
other words, Bohn recites the legal standard to be considered a trade secret and says that
Contour’s IT System fits the bill. However, in reference to the First Bohn Report, Bohn admits
that he does not identify any record evidence in support of that assertion,42 nor does he articulate
any methodology for his conclusions. During his deposition, Bohn gave the following response
when asked about the standard he used:
I think I used a common sense standard; and you can tell me if I’m wrong on this,
but I don’t think I am. We know that to build this system again was going to cost
a million dollars . . . . We know that, clearly, Gridforce thought it had value. They
took it, so clearly it has economic value. I don’t know another way to say that.43
Because “the word ‘knowledge’ connotes more than subjective belief or unsupported
speculation,”44 there is no reliable foundation for an expert utilizing what is described solely as a
“common sense standard.”45 Common sense is what juries bring to the table and therefore this
expert opinion would not assist the jury. Bohn’s IEV opinion in his First Report does not pass
muster under the standards of Rule 702.
Gridforce takes further issue with the Second Bohn Report, characterizing it as an
unpersuasive attempt to rehabilitate Bohn’s IEV opinions. Bohn relies on the following
statements to demonstrate why he believes the IT System has IEV:
1) Gridforce tried to create its own such IT System in 2014 prior to engaging
Contour, but could not;
2) Gridforce paid Contour over $1 million to create the Contour IT System and
then $130,000 a month to use (and manage) it;

45 Byer Decl., Ex. D, Bohn Dep. Tr. [Doc. No. 338-2] at 118.
3) NAES/Gridforce also tried to create their own IT System in 2017, but could not;
4) NAES/Gridforce tried to get several other vendors to create a new IT System to
replace the Contour IT System, but could not find one that could do it for less
than they had paid/were paying Contour;
5) Gridforce terminated the MMSA on February 7, 2020, stopped paying Contour
for use of the Contour IT System, but continued and still continues to use the
Contour IT System without authorization to make money to this day;
6) Contour spent an enormous amount of person hours of highly trained
experienced software engineers, time and money over a year to create the
Contour IT System precisely because no one else had one or could easily do it;
7) In 8 years since Contour created the Contour IT System, no one else has created
one like it and none other is available at any price in the marketplace.46
Gridforce contends that the above statements are not grounded in any concrete evidence,
and that Bohn has not investigated any of these assumptions to confirm their validity.47 Instead,
Gridforce contends, Bohn was provided these assumptions by Guerriero, Contour’s founder, and
Contour’s counsel.48 According to Gridforce, Bohn’s assumption that no one has created an IT
system like this one contradicts his own deposition testimony stating that he has seen similar
systems used elsewhere.49
Contour responds that Bohn “clearly knows” that the IT System is “not generally known
as he knows the business, the marketplace, and knows that no such system is available for sale or
license.”50 Specifically, Contour asserts that Bohn’s IEV opinions are reliable because they are

based on facts in the record, his review and study of the IT System, his many years of experience
in the industry, and his knowledge of the marketplace.51
Third Circuit precedent supports the exclusion of testimony where an expert chooses “to
rely blindly upon the conclusions generated by Plaintiffs[’] other experts . . . .”52 Here, Bohn is
not even relying on other experts, but instead is relying on the statements of Contour’s founder
and its counsel.53 Many of the underlying facts upon which Bohn claims to rely are most fairly
characterized as “subjective belief or speculation.”54 The assumptions upon which Bohn relies
are riddled with unverifiable conjecture and inconsistencies, and his reliance on these
assumptions would invade the fact-finding province of the jury. For example, Contour has not
established how Contour’s founder would have knowledge about Gridforce’s prior attempts to
create an IT System before contracting with Contour. Furthermore, Bohn assumes that Gridforce
continues to use the Contour IT System without authorization to this day. However, this
“assumption,” which Bohn presumes to be a fact based on Guerriero and his counsel’s blanket
statements, is one of the fundamental material disputes of the case. The Court finds that Bohn’s
reports and deposition testimony demonstrate that his IEV opinion is unreliable.
2. Bohn’s Opinions on 70 Pages of Settings
Bohn defines the “IT System” as 94 virtual machines, 40,000 lines of code, and related
firewalls.55 In the Second Bohn Report, Bohn identifies and outlines 70 pages of settings which,
he asserts, provide “a more comprehensive description of the Contents of the 94 Virtual

54 TMI, 193 F.3d at 670.
55 Byer Decl., Ex. A, First Bohn Report [Doc. No. 338-2] at 10.
Machines . . . .”56 Bohn concludes that these 70 pages of settings are evidence that the
IT System, in its entirety, qualifies as a trade secret, but he does not describe any reliable method
for how he reached that conclusion. Notably, Bohn fails to articulate why these 70 pages are the
ones presented in his expert report. Nor does he elaborate upon why he selected settings from
only 58 of the 94 virtual machines. Bohn testified at his deposition that the compilation of
settings in his report was prepared by Jason Smith, his engineer.57 Although “[a]n expert witness
is permitted to use assistants in formulating his expert opinion,”58 reliance on an assistant does
not do away with Rule 702’s fundamental requirement that an expert use “reliable principles and
methods.”59 Bohn testified that he gave Smith direction on “what to look up, what to bring in,
and what to pull,” but at no point has Bohn clarified what those directions were, let alone the
reasoning behind them.60
Contour protests that Gridforce fails to present any supporting expert testimony or
authority for its contention that Bohn’s methodology is unreliable. However, it is Contour’s
burden as the proffering party to demonstrate that its expert has employed a reliable
methodology.61 Likewise, Contour bears the burden of establishing how its expert’s opinion will
be useful to the jury.62 It is neither Gridforce nor the Court’s responsibility to guess at the
56 Byer Decl., Ex. B, Second Bohn Report [Doc. No. 338-2] at 19. Although Bohn opines that each of the 94 virtual
machines constitute a trade secret, Gridforce points out (and Contour appears not to dispute) that the settings he
identifies only appear in 58 of the 94 virtual machines. Gridforce’s Mem. Supp. Mot. Exclude Bohn

significance of 70 pages of IT system settings without proper context. Nor can the Court be
expected to speculate about what methodology may have been used by an expert in a given field.
Here, in the context of a dispute over trade secret classifications, Bohn must describe the
methodologies he employed in evaluating the independent economic value of the IT System, and
he must further clarify how his opinions, based upon his expertise in the field of computer
systems and information technology, would be helpful to laypersons on a jury who do not have
such expertise. Bohn has failed to do so.
District Courts are tasked with considering the factors set forth by the Supreme Court in
Daubert v. Merrell Dow Pharmaceuticals, Inc.63 in evaluating reliability.64 The Court cannot
even begin to apply many of these factors, as Bohn has failed to articulate any methodology for
selecting these 70 pages of settings. Therefore, Bohn’s haphazard selection of the 70 pages of
settings is unreliable and must be excluded.
3. Bohn’s Opinion that Gridforce Took the IT System
Gridforce argues that Bohn’s opinion regarding whether Gridforce “took” Contour’s
IT System (defined as the 94 virtual machines, 40,000 lines of code, and related firewalls) should
be excluded for unreliability. First, Gridforce refers to Bohn’s deposition testimony that he has
no opinion as to “whether Gridforce somehow took [the] code.”65 Second, Gridforce argues that
Bohn deployed a “haphazard, intuitive inquiry” as opposed to a reliable methodology to
63 509 U.S. 569 (1993).
64 District Courts are tasked with considering numerous factors, including: (1) whether a method consists of a
testable hypothesis; (2) whether the method has been subject to peer review; (3) the known or potential rate of error;
(4) the existence and maintenance of standards controlling the technique’s operation; (5) whether the method is
generally accepted; (6) the relationship of the technique to methods which have been established to be reliable;
(7) the qualifications of the expert witness testifying based on the methodology; and (8) the non-judicial uses to
which the method has been put. Pineda, 520 F.3d at 247–48 (citing Paoli, 35 F.3d at 742 n.8).

determine whether Gridforce took the firewalls.66 The PI Report attached to the First Bohn
Report determined that there was a 68% match between Contour and Gridforce’s virtual
machines.67 When asked how he came to this percentage, Bohn stated that he “counted the
number of words to get that total percentage of words and said what percentage of words were
the same.”68 He also stated that he manually excluded words that were common, but failed to
provide a list of the words that were excluded because he “just knew . . . because [he has] been
doing this long enough that these things were common.”69 He did not provide a record showing
what words were excluded.70 Without an understanding of what words were excluded or why,
such an expert conclusion cannot be helpful to a jury. Contour responds that Bohn’s “numeric
methodology is clear, simple and makes logical sense.”71 However, Contour fails to specifically
address any of the concerns raised by Gridforce, and there is no indication that Bohn’s purported
methodology has been peer reviewed, is accepted in the field, or has a discernible rate of error.
Finally, Bohn states that he gathered the system configuration files and code settings of
28 virtual machines provided by Gridforce, and that he performed a side-by-side comparison
with the systems initially provided by Contour.72 Bohn articulated that he could not conduct a
full analysis of all 94 VMs because Gridforce did not produce all of the log files for all 94
VMs.73 Therefore, based on a purportedly limited record, Bohn determined that Gridforce likely

copied 16 of the 28 systems.74 However, such a finding is not helpful to a jury because Bohn
defines the IT System as including 94 VMs. By analyzing only 28 of the 94 VMs, Bohn cannot
reliably reach a determination on whether the IT System was stolen in its entirety.
4. Bohn’s Opinion that the IT System is an Electronic
Communication
Bohn concludes that the IT System was an “electronic communication while it was in
electronic storage” pursuant to 18 U.S.C. § 2701(a)(2) because it was “copied/removed and
transmitted electronically from one computer to another” during the migration.75 Gridforce
argues that this is an improper legal conclusion. Gridforce also notes that Bohn provides no
explanation for his conclusion other than his own say-so. Contour concedes that the Court may
hold that Bohn cannot conclude that anything meets or does not meet statutory definitions such
as “electronic communication” or “electronic storage,” but argues that Bohn does explain how
the IT System meets the statutory definition. The question of whether the IT System qualifies as
an electronic communication pursuant to 18 U.S.C. § 2701(a)(2) is not properly the subject of an
expert report; a jury must apply the facts to the law to make this determination.76 Therefore,
Bohn is precluding from testifying to this conclusion at trial.
“[T]he reliability analysis [required by Daubert] applies to all aspects of an expert’s
testimony: the methodology, the facts underlying the expert’s opinion, [and] the link between the
facts and the conclusion.”77 Because of the methodological weaknesses identified throughout
Bohn’s Expert Reports, the Court concludes that Bohn has failed to apply and articulate a clear

methodology by which he reaches his conclusions. Because the Court finds that Bohn’s opinion
is based upon his failure to faithfully apply reliable methods, and because his testimony is likely
to confuse or mislead the jury, the Court will exclude Bohn’s testimony at trial under Daubert
and Rule 702.
IV. CONCLUSION
For the reasons set forth above, the motion to exclude the opinion of James Thompson
will be granted, and the motion to exclude the opinion of William Bohn will be granted. An
appropriate order follows.
