ORDER
Smith Meter, Incorporated, seeks reversal of an order issued by the United States District Court for the Western District of Pennsylvania, Erie Division, Mise. No. 732, denying its motion to quash a subpoena. 1 We conclude that Smith Meter has nоt established that the district court’s order is appealable. Accordingly, Smith Meter is ordered to show cause why the appeal should not be dismissed.
I
Micro Motion Incorporated sued Exac Corporation in the Northern District of California for infringement of its patents relating to Coriolis mass flowmeters. A jury returned a verdict of noninfringement; however, the district court set aside that verdict and granted Micro Motion a new trial. Micro
Motion, Inc. v. Exac Corp.,
Smith Meter moved the district court in Pennsylvania to quash the subpoena. It sought to prohibit the discovery of its confidential business information which it argued has no legal relevancy to the California litigation. Smith Meter is not a рarty to that suit or any other related litigation; has not been charged with infringement by Micro Motion; and apparently has no business dealings with either litigant. Micro Motion responded that, if it succeeds in its infringement suit against Exac Corporation, the information it seeks could be relevant to its recovery of lost profits as damages, whether or not Smith Meter is also an infringer. Smith Meter asks this court to reverse the district court’s denial of its motion to quash.
The extent to which information on a non-party’s competing product is relevant and discoverable on the issue of damages in a patent suit is a novel and important question. However, sua sponte, this court raises the following jurisdictional issue: Whether an order which denies a motion to quash a subpoena directed to a non-party, to obtain evidence for use in a pending action, is an appealable order where the order is entered by a court other than the court in which the action is pending.

As this court has stated, “thе initial inquiry in any appeal is whether the court to which appeal is taken has jurisdiction to hear the appeal.”
Woodard v. Sage Products, Inc.,
Congress has granted the United States appellate courts jurisdiction over only “fi
*1576
nal decisions” of federal district courts.
See
28 U.S.C. §§ 1291 and 1295(a)(1) (1982). The “finality” rule has a salutary effect. It lessens interruptions in the orderly progress of a suit by eliminating delays incident to fragmentary appeаls, and it brings the matter as a whole before the appellate court.
See United States v. Nixon,
Smith Meter has asserted in its brief, and Micro Motion does not challenge, that this appeal falls within the scope of the decision of this court in
Heat & Control, Inc. v. Hester Industries, Inc., 785
F.2d 1017,
The nonappealability of orders requiring the prоduction of evidence from witnesses has long been established. In
Alexander v. United States,
In a certain sense finality can be asserted of the orders [compelling production] under review, so, in a certain sense, finality can be asserted of any order of a court. And such an order may coerce a witness, leaving to him no alternative but to obey or be punished. It may have the effect and the same characteristic of finality as the orders under review, but from such a ruling it will not be contended there is an appeal. Let the court go further and punish the witness for contempt of its order, then arrives a right of review, and this is adequate for his protection without unduly impeding the progress of the case.... This power to punish being exercised the matter becomes personal to the witness and a *1577 judgment as to him. Prior to that the proceedings are interlocutory in the original suit.
Id.
at 121-22,
[T]he traditional contempt avenue to immediate appeal is peculiarly inappropriate due to the unique setting in which the question arises. To require a President of the United States to place himself in the posture of disоbeying an order of a court merely to trigger the procedural mechanism for review of the ruling would be unseemly, and would present an unnecessary occasion for constitutional confrontation between two branches of the Gоvernment.
Id.
at 691-92,
We are mindful of the harshness inherent in requiring a witness to place themself in contempt to create a final appealable
*1578
decision.
See
R. Stern,
supra,
at 99-101. However, it is all too certain that the consequences of recognizing a
right
to appeal all orders refusing to quash a subpoena, even where such an order “ends” ancillary proceedings against a non-party, would be to “constitute the courts of appeals as second-stage motion cоurts reviewing pretrial applications of all non-party witnesses alleging some damage because of the litigation.”
Borden v. Sylk,
Following hearing on this appeal, in which the matter of jurisdiction was raised, Smith Meter has brought to our attention the recent decision in
Smith v. BIC Corp.,
We have never held as a blanket rule that discovery ordеrs are not appealable. Rather, we address each issue using two vehicles: the collateral order doctrine of Cohen [v. Beneficial Industrial Loan Corp.,337 U.S. 541 ,69 S.Ct. 1221 ,93 L.Ed. 1528 (1949)] and the petition for writ of mandamus.
Id. at 198, 10 USPQ2d at 1054 (emphasis added). In the BIC case, the Third Circuit held that the denial of a protective order was appealable where thе district court had erroneously found the information sought to be protected was not defendant’s trade secret.
Our ruling on finality does not include a
Cohen
analysis. Nor does our decision preclude Smith Meter from pursuing the possibilities of mandamus or seeking certification by the distriсt court of a legal question in accordance with 28 U.S.C. § 1292(b) (1982 & Supp. V 1987).
See Herbert v. Lando,
In view of the foregoing, IT IS ORDERED THAT:
(1) On or before June 21, 1989, Smith Meter is ordered tо show cause why Appeal No. 89-1099 should not be dismissed for lack of jurisdiction.
(2) Any brief or memorandum of Micro Motion and Exac opposing or supporting jurisdiction shall be filed within ten days thereafter.
Notes
. The district court issued a series of orders in connеction with this motion. For purposes of this opinion, we deem the court’s order of September 26, 1988, to be dispositive.
. It was also held to be appealable to this court under
Heat and Control,
. In Solarex, the opinion broadly states that "a ruling" in such ancillary proceeding is deemed final. That statement is correct only where, as in Solarex, the motion to quash is granted.
. “This court has the duty to determine its jurisdiction and to satisfy itself that an appeal is properly before it. Wе may, of course, look for guidance in the decisions of the regional circuit to which appeals from the district court would normally lie, as well as those of other courts. However, our decision to follow another circuit’s interpretation of a common jurisdictional statute results from the persuasiveness of its analysis, not any binding effect."
