Plymovent Corp. v. Air Technology Solutions


August 2, 2007


The opinion of the court was delivered by: Irenas, Senior District Judge



This matter comes before the Court on the appeal of Biological Controls, Inc. ("Biological") from the Magistrate Judge's Order Quashing a Subpoena Duces Tecum seeking disclosure of materials of a non-testifying expert. For the reasons set forth below, the Court will affirm the order.


This is a lawsuit between competitors who manufacture diesel exhaust removal systems, which are used primarily in fire stations. Both systems are meant to remove exhaust emissions from indoor garages. Biological's system, "AirMATION," filters air through a unit mounted on the ceiling of the garage, whereas Plymovent Corporation's ("Plymovent") hose-based system removes exhaust directly from a vehicle's tailpipe through an attached hose.*fn1

The parties' dispute found its way to this Court on January, 20, 2005, when Plymovent filed a complaint against Air Technology alleging false advertising in violation of the Lanham Act, 15 U.S.C. § 1125(a), common law unfair competition, and violation of the New Jersey Consumer Fraud Act, N.J.S.A. § 56:8-19. Plymovent sought preliminary injunctive relief on all three claims.

After expedited discovery, this Court held a preliminary injunction hearing on February 17, 2005.*fn2 In preparation for the hearing, Plymovent retained Atlantic Environmental, Inc., to perform a side-by-side emissions control study comparing the performance of Biological's system with Plymovent's system in a fire station. The control study was videotaped, and Henry P. Shotwell, Ph.D., CIH,*fn3 Atlantic Environmental's Vice President, created an accompanying report. Shotwell essentially concluded that Plymovent's system was effective and Biological's system was not. Plymovent submitted both the videotape and the report to the Court in advance of the preliminary injunction hearing.

The parties do not dispute that Plymovent intended to call Dr. Shotwell to testify as an expert witness at the preliminary injunction hearing, and that he was present in the courtroom on the day of the hearing. However, before Plymovent could call Dr. Shotwell, the Court inquired whether Plymovent would like to reconsider its reliance on the videotape and report. The following exchange occurred on the record:

The Court: [A]re you going to rely on that tape and the report that's based on that tape, or are you going to ignore and proceed without it--- . . . You think that helps your case?

Mr. O'Neill: Absolutely, your Honor. For the purposes of today, it provides--

The Court: You don't want to reconsider that position [?]

Mr. O'Neill: Your Honor, what it does--

The Court: I will give you a chance.

Mr. O'Neill: What it does, you Honor, is it provides the Court with a visual representation--

The Court: It's a travesty of the scientific method, it's a travesty. It's the only word I can think of. I'm not saying that if it's done right you might not reach the same results, but who knows. It's a travesty. . . . I don't have to be much of a scientist to know that that report has about 35 different variables in there, none of which are harmonized. I mean it's a travesty. So, I just want to know if you want to rely on it, or you think you have a good case without it.

Mr. O'Neill: I have a very good case without it.

The Court: All right.

(Schoenfeld Decl. Ex. F, preliminary injunction hearing transcript at p. 11-12).

The Court denied preliminary injunctive relief and the parties proceeded to engage in formal discovery. In the course of discovery, PlymoVent produced the Shotwell Report and videotape to Biological, as well as two Atlantic Environmental invoices charging Plymovent for the emissions study and Mr. Shotwell's attendance at the preliminary injunction hearing.

PlymoVent indicated in its Initial Disclosures,*fn4 dated July 26, 2005, that it was presently in the process of evaluating its need for experts. Similarly, on January 18, 2006, PlymoVent answered Air Technology's and Biological's interrogatories regarding testifying experts by stating that it "has not yet made a decision regarding whom it expects to call as an expert witness at trial."

By a letter dated October 3, 2006, Biological inquired whether PlymoVent intended "to continue" to use Atlantic Environmental as an expert in the case. PlymoVent responded that although it retained Atlantic Environmental in anticipation of litigation or preparation for trial, it did not expect to call any Atlantic Environmental representative as a witness at trial.

PlymoVent never formally designated anyone from Atlantic Environmental as a testifying expert witness.

On November 13, 2006, before the deadline for serving expert reports, Biological served on Atlantic Environmental a subpoena duces tecum, seeking documents "referring or relating to" the Shotwell Report and videotape. Specifically, the subpoena requested:

1. All Documents and Communications related to contracts between PlymoVent . . . or its counsel, Windels, Marx, Lane and Mittendorf, LLP and Atlantic Environmental, Inc., including but not limited to, communications, contracts, proposals, purchase orders, engagement letters, reports, test data, video depictions, notes and invoices relating to work performed by Atlantic Environmental, Inc. for PlymoVent and/or its counsel.

2. All Documents and Communications referring or relating to tests performed by Atlantic Environmental, Inc. on the AirMation air filtration product.

3. All Documents and Communications referring or relating to tests performed by Atlantic Environmental, Inc. on PlymoVent's diesel exhaust hose extraction system and components thereof.

4. All Documents and Communications referring or relating to comparison tests of the PlymoVent and AirMation systems performed by Atlantic Environmental, Inc.

(Schoenefeld Decl. Ex. J).

Plymovent moved to quash the subpoena, and on May 14, 2007, Magistrate Judge Schneider heard arguments on the motion. He granted the Motion to Quash holding that, as a non-testifying expert, Atlantic Environmental's records were protected under Fed. R. Civ. P. 26(b)(4)(B) because Biological had not demonstrated "exceptional circumstances," as required by the rule. This appeal followed.


The District Court has jurisdiction to hear appeals from the Magistrate Judge pursuant to 28 U.S.C. § 636(b)(1)(A). The provision reads in relevant part: "[A] judge may designate a magistrate judge to hear and determine any pretrial matter pending before the court . . . [and] may reconsider any pretrial matter under this subparagraph (A) where it has been shown that the magistrate judge's order is clearly erroneous or contrary to law." 28 U.S.C. § 636(b)(1)(A).

The District Court applies a clearly erroneous standard of review to findings of fact and conducts a plenary review of matters of law. Haines v. Liggett Group Inc., 975 F.2d 81, 91 (3d. Cir. 1992); see also Fed. R. Civ. P. 72(a).


Rule 26(b)(4) addresses the scope and limits of discovery with respect to testifying and non-testifying experts respectively:

(A) A party may depose any person who has been identified as an expert whose opinions may be presented at trial. . . .

(B) A party may, through interrogatories or by deposition, discover facts known or opinions held by an expert who has been retained or specially employed by another party in anticipation of litigation or preparation for trial and who is not expected to be called as a witness at trial only as provided in Rule 35(b)*fn5 or upon a showing of exceptional circumstances under which it is impracticable for the party seeking discovery to obtain facts or opinions on the same subject by other means.

Fed. R. Civ. P. 26(b)(4)(A)-(B). Rule 26(b)(4)(B) thus creates a safe harbor whereby facts and opinions of non-testifying, consulting experts are shielded from discovery, except upon a showing of exceptional circumstances. Indeed, some courts have construed 26(b)(4)(B) as creating a privilege against disclosure.*fn6

Several policy considerations underlie the rule, including, (1) encouraging counsel to obtain necessary expert advice without fear that the adversary may obtain such information; (2) preventing unfairness that would result from allowing an opposing party to reap the benefits from another party's efforts and expense; (3) preventing a chilling effect on experts serving as consultants if their testimony could be compelled; and (4) preventing prejudice to the retaining party if the opposing party were allowed to call at trial an expert who provided an unfavorable opinion to the party who first retained them. See Callaway Golf Co. v. Dunlop Slazenger Group Americas, Inc., 2002 U.S. Dist. LEXIS 15429 at *5 n.3 (D. Del. Aug. 14, 2002).*fn7 Moreover, while discovery with respect to testifying experts is essential to allow opposing counsel to adequately prepare for cross-examination, and to eliminate surprise at trial, "there is no need for a comparable exchange of information regarding non-witness experts who act as consultants and advisors to counsel regarding the course litigation should take." Mantolete v. Bolger, 96 F.R.D. 179, 181 (D. Ariz. 1982).

Biological re-asserts on appeal the two arguments it made below. First, it asserts that Rule 26(b)(4)(B) does not apply in this situation at all, because Biological only seeks to compel production of documents, not to depose or propound interrogatories on Atlantic Environmental. Because the rule only speaks of discovery "through interrogatories or by deposition," they reason that it simply does not cover this situation, thereby leaving only the general discovery rule, Rule 26(b)(1), as the applicable provision.

Second, Biological asserts that even if Rule 26(b)(4)(B) does apply, Plymovent waived the rule's protection by submitting the control study video and Shotwell report in support of its motion for preliminary injunction, having Shotwell ready to testify at the hearing, and voluntarily producing the video and report in discovery.


Magistrate Judge Schneider rejected Biological's first argument, explaining that if the Court were to accept Biological's reasoning, any party could completely circumvent Rule 26(b)(4)(B) simply by serving a document subpoena.

The Magistrate's decision on this issue is not contrary to law. Many of the rule's underlying policy concerns would be undermined if Biological's argument were accepted. Biological is just as likely to reap the benefits of Plymovent's work by obtaining documents as it would through deposition testimony or interrogatory answers. Compelling disclosure of documents would have the same chilling effect on free consultation between a retaining party and its expert as compelling a deposition or answers to interrogatories. Thus, the Magistrate's reasoning was correct--- holding that Rule 26(b)(4)(B) does not apply would allow an end run around the policies of the rule.

Moreover, case law suggests that Rule 26(b)(4)(B) should not be so narrowly interpreted.*fn8 In In re: Painted Aluminum Products Antitrust Litigation, the Defendant sought to quash a document subpoena served upon its non-testifying expert. 1996 U.S. Dist. LEXIS 9911 at *2 (E.D. Pa. July 8, 1996) (Pollak, J.). While the court ultimately denied the motion to quash, holding that the expert had not been retained "in anticipation of litigation" (a point not disputed in this case), with respect to the rule's limitation to depositions and interrogatories, the court observed, "[the rule] does not speak to requests for the production of documents under Fed. R. Civ. P. 45. However, it is by now a truism that the various discovery devices function as an integrated system, and that in deciding the limits of privilege, we should treat the various devices similarly." Id. at *3. Likewise, the Court in Vincent v. Morton, albeit without discussion of the issue, applied Rule 26(b)(4)(B) to deny a motion to compel responses to twelve requests for production of documents served upon a party's non-testifying expert. 2006 U.S. Dist. LEXIS 60442 at *2 (D. Conn. Aug. 11, 2006).

Because the Magistrate's decision is supported by Rule 26(b)(4)(B)'s policy considerations and case law, the Court will affirm the decision that Rule 26(b)(4)(B) applies to the present discovery dispute.


The Magistrate also correctly held that under the particular circumstances of this case, Plymovent's reliance (or attempted reliance) on the videotape and report at the preliminary injunction hearing did not effect a waiver of Rule 26(b)(4)(B)'s protection. Relying on Callaway Golf, 2002 U.S. Dist. LEXIS 15429 at *5, the Magistrate concluded that no waiver occurred because Plymovent "pulled back" its expert before he testified at the hearing, and in any event, this Court, as clearly indicated in the hearing transcript, did not give the videotape and report any weight.*fn9

Callaway Golf is both similar to and different from this case. In Callaway Golf, a party changed the designation of its expert from testifying to non-testifying. 2002 U.S. Dist. LEXIS 15429 at *3. The expert was withdrawn as a testifying expert after his deposition was scheduled, and after his expert report had been provided to the opposing party, but before his deposition actually took place. Id. at *1-2. After analyzing other cases addressing the issue, the Court concluded,

A common theme is apparent throughout the cases reviewed from various jurisdictions -- the conversion of an expert designated for trial purposes under Rule 26(b)(4)(A), to a consulting expert, under Rule 26(b)(4)(B) is allowed and results in insulating that expert from discovery, absent the showing of exceptional circumstances. Although some of the cases identified herein by the parties did not indicate whether disclosure of the opinions had occurred before the change in designation, in those cases where such disclosure had clearly occurred . . . the analysis was consistent between those two cases, as well as with the non-disclosure cases. Divulging the expert opinions did not alter the analysis.

Id. at *11-12. Accordingly, the court held that the opposing party was not entitled to depose the redesignated expert absent exceptional circumstances, unless the deposition was limited to facts and opinions that the expert developed before he was hired as an expert witness. Id. at *12-13

The question is whether the differences in this case compel a different result from Callaway Golf. On one hand, because of the differing procedural posture of this case, Plymovent never designated Atlantic Environmental as a testifying witness, a fact which at least one court, in different circumstances, has considered determinative.*fn10 On the other hand, not only did Plymovent disclose the videotape and report, it initially relied on those materials in support of its preliminary injunction motion before withdrawing its reliance at the preliminary injunction hearing. Some courts have held, again under somewhat different circumstances, that disclosure or reliance on a non-testifying expert's facts and opinions waives Rule 26(b)(4)(B)'s protection;*fn11 while others, like the court in Callaway Golf, have ruled that disclosure does not automatically waive protection.*fn12

As the Magistrate noted, however, none of the cases are closely analogous to this case on all relevant points. At the time of the decision below, there was no case that involved disclosure of an expert's facts and opinions at a very early point in the litigation, reliance on the expert's facts and opinions, and then withdrawal of that reliance before the Court reached a decision. Fortunately, since the decision below, such a case has been decided.

In Intervet, Inc. v. Merial Limited, 2007 U.S. Dist. LEXIS 44970 (D. Neb. June, 20, 2007), the court quashed a subpoena served on an expert who had previously submitted a declaration in support of a motion for preliminary injunction in a separate but related litigation, involving the same parties.*fn13 The party seeking to depose the "consulting expert" asserted that Rule 26(b)(4)(B)'s protection was waived by the use of the expert's declaration. Id. at *4. The court explained,

The court rejects Merial's argument that all Rule 26(b)(4)(B) protection was waived due to the filing of Dr. Osorio's declaration in the [prior] Georgia action. Compliance with the disclosure requirements of Rule 26(a)(2)(B) was not mandatory in that context. Rule 26(b)(4)(B) allows the deposition of expert witness 'whose opinions may be presented at trial.' (Emphasis added). Dr. Osorio was not designated as a testifying expert in the Georgia case. At the time the case was dismissed, Dr. Osorio's opinions would not have been admissible at trial due to lack of compliance with Rule 26(a)(2)(B). Furthermore, the Georgia case was dismissed for reasons unrelated to the merits of the case - the court found that Merial lacked Article III standing to bring the lawsuit, and Merial's motions for temporary restraining order and for preliminary injunction were dismissed as moot.

Id. at *4 (emphasis in original).

The Court concludes that the same result should obtain here. As in Intervet, no relief was granted on the basis of the expert's materials submitted in support of the preliminary injunction application. Additionally, given the Georgia court's holding with regard to standing, the court must not have given the expert's declaration any weight because the declaration regarding the merits of the patent dispute was irrelevant to the jurisdictional issue. Likewise here, the Court did not give the Shotwell report and videotape any weight in its analysis, finding that the expert's materials were not scientifically reliable.

Given these facts, the Court concludes that Plymovent's withdrawal of its expert at the preliminary injunction hearing was effective and its limited reliance on the Shotwell Report and videotape did not waive the protection afforded to non-testifying experts under Rule 26(b)(4)(B).*fn14 Thus, Biological may only obtain the documents sought upon a showing of exceptional circumstances.

Before the Magistrate, Biological apparently asserted that it would be extremely difficult for it to obtain access to a fire station facility in which it could test Plymovent's filtration system.*fn15 However, the Magistrate correctly observed that Biological presented no evidentiary support for its contention and did not even assert that it had made an attempt to gain access to a facility. Moreover, on appeal, Biological makes no argument with respect to exceptional circumstances.

Because this Court holds that no waiver occurred and that Biological has not established exceptional circumstances to overcome the protection of Rule 26(b)(4)(B), the Magistrate's decision will be affirmed.*fn16


For the reasons set forth above, the Court will affirm the Magistrate Judge's Order Quashing Subpoena Duces Tecum. An appropriate order will be issued.
