MEMORANDUM OPINION AND ORDER

Continental Automotive Systems US, Inc. (“Continental”) has sued Schrader Electronics,

Inc. in the Eastern District of Michigan for patent infringement. Automotive Systems US, Inc. v.

Schrader Electronics, Inc., et al., No. 2:11-cv-14525 (E.D. Mich.). The patent at issue involves a

sensor manufactured by Schrader that measures tire pressure and sends that information to a receiver

in the vehicle. The receiver is manufactured by Continental, Omron and others. In the wake of the

district court’s Markman ruling, Continental issued a Rule 45 subpoena to Omron, an innocent, nonparty to the patent action. Omron is a direct competitor of Continental. 

A.

 The information that Continental seeks encompasses a wide variety of technical, proprietary

information – specifically, technical specifications pertaining to how Omron’s receivers process the

information they receive from tire pressure sensors. Simply stated, the subpoena calls for the

production of all “technical documents” “related to all of Omron’s [tire pressure monitoring]

receivers.” (Continental Memorandum at 8) The subpoena also sought a witness to testify at a

deposition regarding the operation of the receivers and the documents to be produced should that

2:14-cv-14617-SJM-MJH Doc # 4 Filed 12/08/14 Pg 1 of 9 Pg ID 103
prove to be necessary. Not surprisingly, Omron is unwilling to divulge this information to

Continental, which, according to Omron, is its number one competitor in the industry. Expressing

surprise at Omron’s unwillingness to share its most valuable corporate asset with a competitor,

Continental filed the instant motion to compel. 

 Continental submits that the information it seeks is “indisputably relevant” to its patent

infringement claim against Schrader because “at least the ‘019 patent contains claims that implicate

functionality which may be executed by the . . . receiver or related components (as opposed to the

sensor itself).” (Continental Memorandum at 5). The Memorandum does not go beyond this ipse

dixit and cites nothing in support of it. Indeed, only one case is cited in the Memorandum, Purzel

Video GmbH v. Does 1-108, 2013 WL 6797364, 9 (N.D.Ill.2013), and that for the general

proposition that the mere burden of finding and producing documents is not considered undue.

(Memorandum at 8). Apart from the fact that “general propositions do not decide concrete cases,”

Lochner v. New York, 198 U.S. 45, 76 (1905)(Holmes, J., dissenting), relevancy, not burden, is the

focus of Omron’s objection to the subpoena.

Omron contends that Judge Murphy’s claim construction ruling “eviscerated” Continental’s

claim for direct patent infringement against Schrader because a tire pressure monitor sensor located

in a car wheel cannot generate an alarm detectable by human beings, as the patent requires.

(Memorandum at 1– 2, 7 et. seq.). Consequently, Omron argues, Schrader could not be a direct

infringer, and absent direct infringement there cannot be indirect patent infringement.

(Memorandum at 8). Proceeding from this premise, Omron concludes that since the claims against

Schrader “cannot be proven as a matter of law,” the information sought by Continental is simply not

relevant. (Memorandum at 10).

2:14-cv-14617-SJM-MJH Doc # 4 Filed 12/08/14 Pg 2 of 9 Pg ID 104
At the hearing on its motion, Continental disagreed with Omron’s interpretation of Judge

Murphy’s Markman ruling and Omron’s bleak assessment of the continued viability of its patent

infringement claim, which is now based on the theory that everyone who drives a car containing an

Omron receiver and a Schrader tire pressure sensor is a direct infringer and Schrader is a

contributory infringer. Omron’s Memorandum contains an extended discussion of direct and indirect

patent infringement and of the Michigan court’s rulings. It cites a number of patent cases, including

the Supreme Court’s June 2, 2014 decision in Limelight Network is, Inc. v. Akamai Technologies

Inc. (Memorandum, Ex. 10). 

 Continental conceded, as candor required, that if Omron’s interpretation of patent law was

correct that it would have no case, and any information sought from Omron would obviously then

be irrelevant. And in that setting, the burden of compliance with Continental’s subpoena would

obviously exceed the benefit of production of the material sought. Nw. Mem'l Hosp. v. Ashcroft, 362

F.3d 923, 927 (7th Cir.2004). But Continental had a very different interpretation of Limelight

Network is, Inc. and of the theory of indirect patent infringement. 

What the oral argument showed was that a determination of whether Continental is entitled

to the discovery it seeks from Omron – that is, whether it is relevant to a claim or defense in the

Michigan litigation – is inextricably bound up with the merits of that litigation. Cf., Truswal

Systems Corp. v. Hydro-Air Engineering, Inc., 813 F.2d 1207, 1212 (Fed. Cir.1987)( “a

determination of relevance implicates the substantive law of patent validity and infringement.”).

Under Fed.R.Civ.P. 45(f), an enforcing court may transfer a motion to the issuing court if

the enforcing court finds there are “exceptional circumstances.” The Advisory Committee note to

Rule 45(f) provides guidance on what might constitute such circumstances:

3

2:14-cv-14617-SJM-MJH Doc # 4 Filed 12/08/14 Pg 3 of 9 Pg ID 105
The prime concern should be avoiding burdens on local nonparties subject to

subpoenas, and it should not be assumed that the issuing court is in a superior

position to resolve subpoena-related motions. In some circumstances, however,

transfer may be warranted in order to avoid disrupting the issuing court's

management of the underlying litigation, as when the court has already ruled on

issues presented by the motion or the same issues are likely to rise in discovery in

many districts. Transfer is appropriate only if such interests outweigh the interests

of the nonparty served with the subpoena in obtaining local resolution of the motion.

 Delving into the merits of the litigation in the Eastern District of Michigan constitutes

disrupting that court’s management of the underlying litigation. A ruling here may turn out to be

inconsistent with the rulings in the Michigan case. See Wultz v. Bank of China, Ltd., 2014 WL

2257296 (D.D.C. 2014); Chem-Aqua, Inc. v. Nalco Co., 2014 WL 2645999 (N.D.Tex. 2014); FTC

v. A+ Fin. Ctr., LLC, 2013 WL 6388539 (S.D.Ohio 2013). In this case, ordering compliance with

Continental’s subpoena involves far more than merely ordering discovery of matters that are

connected perhaps only loosely to the case, pending elsewhere. Generally, in that context, courts

must be “especially hesitant to pass judgment on what constitutes relevant evidence.” Truswal

Systems Corp. v. Hydro–Air Eng'g, Inc., 813 F.2d 1207, 1212 (Fed.Cir.1987). Rather, it would

involve determining a question that lies at the heart of the Michigan litigation – namely whether

Continental even has a viable patent case against Schrader after the Markman ruling. Accordingly,

this matter is transferred to the issuing court for resolution.

B.

If this issue were not present, I would deny Continental’s motion. Rule 45 contains

important provisions to protect the recipient of a subpoena from undue burden or expense, invasion

of a privilege, or disclosure of protected material. S.E.C. v. Hyatt, 621 F.3d 687, 694 (7th Cir. 2010).

Under Rule 45(d)(3)(A)(iii), a court must quash a subpoena that requires disclosure of protected

4

2:14-cv-14617-SJM-MJH Doc # 4 Filed 12/08/14 Pg 4 of 9 Pg ID 106
information. One can imagine no more harmful type of disclosure of technical information of the

type sought here than to a direct competitor. It’s a blatantly obvious point. See Am. Standard Inc.

v. Pfizer Inc., 828 F.2d 734, 741 (Fed.Cir. 1987)(courts presume that disclosure to a competitor is

more harmful than disclosure to a non-competitor); Albany Molecular Research, Inc. v. Schloemer,

274 F.R.D. 22, 25 (D.D.C. 2011); In re Vitamins Antitrust Litigation, 267 F.Supp.2d 738, 741-42

(S.D.Ohio 2003); Greater Rockford Energy and Technology Corp. v. Shell Oil Co., 138 F.R.D. 530,

537-538 (C.D.Ill. 1991).1

Moreover, it has become apparent from discussions at the hearing that Continental has other

sources from which it can obtain the information it actually needs for its litigation against Schrader,

namely, from the automobile manufacturers. When questioned about these alternative sources,

Continental’s lawyers argued that only Omron would be able to understand and explain how its

receiver worked in tandem with the Schrader tire pressure monitor. Of course, there is no basis for

this conclusion, and unsupported statements by lawyers whether in briefs, United States v. Stevens,

500 F.3d 625, 62 -629 (7th Cir. 2007); United States ex rel. Feingold v. AdminiStar Federal, Inc.,

324 F.3d 492, 494 (7th Cir. 2003); Credit Corp. v. Aliano Brothers General Contractors, Inc., 437

F.3d 606, 610-611 (7th Cir. 2006), or in oral argument, In re: Payne, 431 F.3d 1055, 1066 (7th Cir. 

2005), don’t count. 

Common sense and human experience – which always have a role to play, United States v.

Montoya De Hernandez, 473 U.S. 531, 542 (1985); Greenstone v. Cambex Corp., 975 F.2d 22, 26

(1st Cir.1992) (Breyer, C.J.); Cooney v. Rossiter, 583 F.3d 967, 971 (7th Cir.2009); Posner, How

 It is undisputed that the information sought by Continental is proprietary, confidential, and only

distributed on a need to know basis. It is information not disclosed to the public or competitors. See Omron

Memorandum, Ex. 10, Declaration of Brian Sample.

5

2:14-cv-14617-SJM-MJH Doc # 4 Filed 12/08/14 Pg 5 of 9 Pg ID 107
Judges Think at 116 (Harv. Univ. Press 2008) – strongly suggest that the major automobile

companies who are the purchasers of the Schrader tire pressure monitor and the Omron receiver are

ready sources of the information Continental says it needs to pursue its theory of the case against

Schrader. It is certain that they know whether Omron receivers are combined with Schrader sensors

in the cars they manufacture, and they would have an intimate knowledge of how the two function

and interact. It is more than a reasonable inference that the automobile manufacturers employ skilled

electrical engineers responsible for insuring the safe operation of a system that is an important safety

component of the vehicles in which they are installed. To do so, they must have a detailed

understanding of how the two function together.

Requiring Continental to pursue these alternative sources of information does not merely

shift the burden from one nonparty to another, with no gain to either and equal burdens to both. In

the context of this case, the nonparties are not fungible. The major automobile companies are not

competitors of Continental. They certainly can provide certain of the information being sought and

it is likely that they will be able to provide sufficient information that will satisfy Continental

without requiring the blanket turnover of the core of Omron’s proprietary information. 

In the last analysis, the decision of whether to require a nonparty to provide information

pursuant to subpoena, like all discovery disputes, falls within the extraordinarily broad range of

discretion invested in judges by the Federal Rules of Civil Procedure. Cf. Crawford-El v. Britton,

523 U.S. 574, 598 (1998); Semien v. Life Insurance Co. of N.A., 436 F.3d 805, 813 (7th Cir. 2006). 

Discretion denotes the absence of a hard and fast rule. Langnes v. Green, 282 U.S. 531, 541 (1931); 

Pruitt v. Mote, 2006 WL 3802822 (7th Cir. 2006); Rogers v. Loether, 467 F.2d 1110, 1111-12 (7th

Cir. 1972)(Stevens, J.). Thus, on virtually identical facts, two decision-makers can arrive at opposite

6

2:14-cv-14617-SJM-MJH Doc # 4 Filed 12/08/14 Pg 6 of 9 Pg ID 108
conclusions, both of which constitute appropriate exercises of discretion. See United States v. Banks,

546 F.3d 507, 508 (7th Cir. 2008); Johnson v. Daley, 339 F.3d 582, 593-594 (7th Cir. 2003)(“the

district judge's substantial discretion...ensures inconsistency.”). 

Omron’s overarching interest in protecting its confidential information from its most

significant competitor counsels against an exercise of discretion that would result in the enforcement

of the Continental subpoena. It is not a sufficient answer to say, as Continental does, that it is willing

to enter into an appropriate protective order with an attorney’s eyes only provision that would

preclude disclosure to anyone other than counsel and experts. Where, as here, there is an alternative

source of the information being sought – and in the absence of a clear showing of relevancy – a

competitor ought not be forced to take the risk that there could be of a violation of a protective order. 

That risk is one that a party must, of necessity, endure.2

 But it is not one that a nonparty

ought to be forced to take where the party seeking the information is its foremost competitor and

there appear to be alternative sources of information. The inescapable reality is that once an expert

– or a lawyer for that matter – learns the confidential information that is being sought, that individual

cannot rid himself of the knowledge he has gained; he cannot perform a prefrontal lobotomy on

himself, as courts in other contexts have recognized. Cf. AMP Inc. v. Fleischhacker, 823 F.2d 1199,

1205 (7th Cir. 1987). See also BASF Corp. v. United States, 321 F.Supp.2d 1373, 1380 (CIT

2004)(“It is very difficult for the human mind to compartmentalize and selectively suppress

information once learned, no matter how well-intentioned the effort may be to do so.”).

 Even in that context, “[w]hen a party is concerned about the competitive misuse of confidential

information and a protective order appears to be insufficient protection, the court must balance the risk of

disclosure to competitors against the risk of damaging the claims or defenses of the party seeking access.” 

Isis Pharmaceuticals, Inc. v. Santaris Pharma A/S Corp., 2013 WL 3367575, 3 (S.D.Cal.2013).

To question the efficacy of a protective order in the context of a case like this is not in any

way to question the integrity of counsel or, indeed, of the experts they plan to employ. Autotech

Technologies Ltd. Partnership v. Automationdirect.com, Inc., 237 F.R.D. 405 (N.D.Ill. 2006) put

it this way:

We begin by crediting fully the sincere assurance that Autotech's in-house counsel

will endeavor to abide by any attorneys-eyes-only protective order that is entered.

But acceptance of that assurance marks the beginning and not the end of analysis.

Brown Bag Software, 960 F.2d at 1471. As the D.C. Circuit said years ago, “the court

does not in any way doubt the faithfulness of house counsel in endeavoring to abide

by the terms of any protective order. The issue concerns not good faith but risk of

inadvertent disclosure.” FTC v. Exxon Corp., 636 F.2d at 1350.FN4 Just as

“[i]nadvertence... is no respecter of its victims,” United States Steel, neither is it a

respecter of the integrity of those who fall prey to it.

Id. at 408

In Litton Industries v. Chesapeake & Ohio Ry., 129 F.R.D. 528, 531 (E.D.Wis.1990), the

court persuasively explained why, in the context of a case like this involving a demand by a

competitor for confidential information, a protective order may not sufficiently eliminate the risk

of real harm:

Once an expert has digested this confidential information, it is unlikely that the

expert will forget. The expert's raison d'etre is to assimilate information in his or her

chosen field and formulate that material into various theories. The information

obtained ... will be added to the expert's repository of other information for possible

future use. Even with stern sanctions for unauthorized disclosure, how does one

practically police a protective order? If the expert is called upon two years after this

litigation to assist a potential competitor in structuring its business, will he really be

able to compartmentalize all he or she has learned and not use any of the information

obtained ...?

“There is a constant danger inherent in disclosure of confidential information

pursuant to a protective order. Therefore, the party requesting disclosure must make

a strong showing of need, especially when confidential information from a nonparty

is sought.” 

Id., at 531. Accord U.S. Gypsum Co. v. Lafarge North American, Inc., 2004 WL 816770, *1

2:14-cv-14617-SJM-MJH Doc # 4 Filed 12/08/14 Pg 8 of 9 Pg ID 110
(N.D.Ill. 2004); Greater Rockford Energy and Technology Corp., 138 F.R.D. at 538; Stanley Works

v. Newell Co., 1992 WL 229652, *5 (N.D.Ill. 1992). 

There is then a real and appreciable risk either that the lawyers or the experts in this case

will, at some point in the future, be in a situation where the information obtained under Continental’s

proposed protective order could not help but be utilized by them and in a way that could have

significant adverse consequences for Omron’s business. While that risk is inherent in any case, it

is one that ought not to be taken where one competitor seeks the confidential, proprietary

information of another competitor who is not a party to the litigation and the most serious questions

are raised as to the relevancy of the information and there are alternative sources from which the

information sought can be obtained elsewhere. 

CONCLUSION

For the reasons discussed in the Memorandum Opinion and Order of 6/20/14, pursuant to

FRCP 45(f), this case should be transferred to Judge Murphy in the Eastern District of Michigan.

To the extent that I do not have jurisdiction to transfer the case, I recommend that Judge Chang do

so. Enter Memorandum Opinion and Order. Alternatively, the motion is denied.
