RULING ON DEFENDANTS’ MOTION TO DISMISS
This motion to dismiss presents in an unusual procedural posture an important question of the reach of this Court’s in personam jurisdiction. Plaintiff Cryomedics, Inc. (“Cyromedies”) is a Connecticut corporation engaged in the manufacture and sale of cryosurgical instruments that are sold to hospitals and surgeons. Defendants Spembly, Limited *288 and Spembly Technical Products, Limited (referred to jointly as “Spembly”) are incorporated under the laws of Great Britain and have their principal place of business in England. Spembly is also engaged in the manufacture and sale of cryosurgical instruments. This action arises under the patent laws of the United States, 35 U.S.C. §§ 271, 281. In the first three counts of its complaint, Cryomedics сharges that Spembly has infringed, actively induced the infringement, and contributed to the infringement of its United States patent 3,696,813 (“the '813 patent”), in violation of 35 U.S.C. § 271. Count IV seeks a declaration that Spembly's United States patent 3,502,081 (“the ’081 patent”) in invalid and not infringed by Cryomedics. 1 28 U.S.C. § 2201. Spembly has moved to dismiss all four counts on the ground that it is not subject to the in personam jurisdiction of this Court, Fеd.R.Civ.P. 12(b)(2). Spembly has also moved to dismiss Count IV on the ground that there is no justiciable controversy between it and Cryomedics with respect to the ’081 patent, and that this Court therefore lacks jurisdiction over the subject matter, Fed.R.Civ.P. 12(b)(1).
With respect to
in personam
jurisdiction, Spembly does not now contest Cryomedics’ claim that the Connecticut corporate long-arm statute, Cоnn.Gen. Stat. § 33-411(c), provides a basis for service of process on it. See Fed.R.Civ. P. 4(e), 4(i)(l)(D)

Section 33-411(c) has been construed “to extend Connecticut’s jurisdictional reach to the constitutional limits,”

Sterling Extruder Corp.,
The argument as advanced by Spembly is based on two propositions: first, that
International Shoe Co.
v.
Washington,
*289
Cryomedics resists the claim of insufficient contacts on two fronts. It contends, first, that it has alleged sufficient contacts with Connecticut to meet the constitutional requirements, see note 3,
swpra,
and, second, thаt Spembly’s status as an alien permits this Court to consider the aggregate of Spembly’s contacts with the United States as a whole. See
Honeywell
v.
Metz, supra,
Taking as true the allegations of the complaint as supplemented by affidavit and particularized in Cryomedics’ memorandum, Spembly has the following contacts with Connecticut. 5 Storz Instrument Co., described аs a “sub or dealer under” Keeler, Inc., one of Spembly’s two primary distributors in the United States, has at least one salesman who solicits in Connecticut. Storz has offered infringing and other Spembly equipment for sale in Connecticut. Keeler itself has made at least one sale in Connecticut of Spembly equipment, although the complaint dоes not allege the sale was of equipment that infringes the ’813 patent. Elmed, Inc., Spembly’s other primary American distributor, also has representatives who solicit and who have sold at least one item of infringing Spembly equipment in Connecticut. Cryomedics also alleges that Spembly has caused Elmed and Keeler to sue Cryomedics in Connеcticut, that a director of Spembly met once in Connecticut with Cryomedics’ president, and that Spembly has a Connecticut licensee that apparently is independent of Spembly and does not manufacture or deal in Spembly equipment. Spembly, of course, describes these contacts in more limited terms and disputes the significance of those that it admits. Other than the charges of voluntary involvement in litigation in Connecticut, and the related allegation that Spembly has agreed to indemnify its distributors for losses incurred in defending and prosecuting the patent actions, Cryomedics has offered no evidence of the relationship between Spembly and its distributors.
In
Honeywell
v.
Metz, supra,
the Cоurt observed that there is no easy formula for determining whether contacts are sufficient to comply with due process, and that a court must determine on a case-by-case basis whether a non-resident defendant “can be said to have invoked, by act or conduct, the benefits and protection of the laws of the forum.”
The relative sparseness of the allegations about Spembly’s relationship with
*290
its American distributors,
6
and about their relationship with Connecticut, is a matter of some consequence if jurisdiction over Spembly is to be tested by its contaсts with Connecticut; this Circuit requires, in a suit to recover for injury caused within a state by conduct occurring without the state, more of a showing of foreseeability for jurisdictional purposes than the “rather low floor of foreseeability necessary to support a finding of tort liability.”
Leasco Data Processing Corp.
v.
Maxwell,
The person sought to be charged must know, or have good rеason to know, that his conduct will have effects in the state seeking to assert jurisdiction over him. Ibid.
Absent such a showing of foreseeability, contact with Connecticut is merely fortuitous and not an intentional invocation of the state’s protection, and is an insufficient basis for jurisdiction. Compare id. at 1341-42 n. 11. This more stringent standard may well have been mеt in Honeywell, although the Court of Appeals apparently applied the less rigorous standard. Metz’s relationship with its distributor was a close one, and Metz appears to have known that it was incorporated in Illinois and that a Chicago dealer was retailing its products.
In the present case, it is a close question whether Spembly had “good reason” to know its products would be sold in Connecticut, or whether it was more like the alien defendant in

v.
Grant,

tacts have all agreed that aggregation of an alien defendant’s contacts with the Unitеd States is the proper procedure in a case arising under federal law.

Brunswick Corp.,
Due process or traditional notions of fair play and substantial justice should not immunize an alien defendant from suit in the United States simply because each state makes up only a fraction of the substantial nationwide market for the offending product.362 F.Supp. at 728 .
It is difficult to see how
International Shoe
and its progeny, which dealt with the limits on the jurisdiction of state courts, and on which Spembly bases its argument, could be read to limit the jurisdiction of a federal court on a federally-created cause of action, see
First Flight Co.
v.
National Carloading Corp.,
Analysis of the principal interest protected by
International Shoe
also suggests that wholesale importation of its strictures into federal question litigation in federal court is improper, at least when an alien defendant is involved.
*292
When a defendant is a citizen of the United States, there are very real differences in convenience between litigating in a state where it does business or resides, and in one where it has only insignificant contacts; this concern is an important consideration underlying the Fourteenth Amendment’s restrictions on the reach of state court jurisdiction. The considerations are entirely different, however, when an alien is involved, especially one like Spembly, which transacts business in the United States only through other companies, and which maintains a place of business only in the country of its incorporation. Spembly has no reason based on fairness to prefer any one particular district to any other, compare
Oxford First Corp.
v.
PNC Liquidating Corp.,
In light of these principles, Spembly’s motion to dismiss the first three counts because of the claimed insufficiency оf its contacts with Connecticut must be denied. Cryomedics has alleged substantial contacts with the United States, and at oral argument Spembly conceded that it could not successfully resist personal jurisdiction in the action pending against it in the Eastern District of Pennsylvania.
With respect to Count IV of the complaint, the constitutional issue is. the same, Spembly’s argument to the contrary notwithstanding. The same activities that required the Court to find contacts with the United States sufficient to support personal jurisdiction on the infringement counts also suffice to supply that jurisdiction on the count seeking a declaration that Spembly’s ’081 patent is void and not infringed. Gerber Scientific Instrument Co. v. Barr and Stroud Ltd., 383 F.Supp 1238 (D.Conn.1973), does not require a different result. It holds only that when an alien patentholder’s only alleged contact, either with the forum or with the United States as a whole, is the “bare unasserted statutory power’’ to sue, its patent can be the subject of litigation only in the District of Columbia. 35 U.S.C. § 293. Spembly has sufficient contacts with the United States so that it does not fall within § 293’s coverage.
The dispute concerning this Court’s jurisdiction over the subject matter of Count IV is essentially a battle of conflicting affidavits, and ■ Spembly’s is not sufficient to prevail. Cryomedics has submitted the affidavit of its president alleging in detail the content of a series of Communications from Spembly to Cryomedics, and claims that these communications amount tо threats that Spembly would bring an infringement action against Cryomedics in the United States to protect Spembly’s ’081 patent. 9 Spembly’s response is the conclusory denial in the affidavit of its director, Hilton Thomas, that it ever threatened, or authorized anyone to threaten, an infringement action against Cryomedics; the affidavit does not deny that the communications detailed in the Cryomedics’ affidavit took place. While perhaps not clearly threatening, the communications alleged might very well have been intended and perceived as threats. In the context of the parties’ frequently hostile commercial relationship, Cryomedics has made a sufficient shоwing of a real controversy, see Muller v. Olin Mathieson Chemical Corp., 404 *293 F.2d 501 (2d Cir. 1968). Compare Gerber Scientific Instrument Co. v. Barr and Stroud, supra.
Accordingly, Spembly’s motion to dismiss is denied.
Notes
. Three other actions involving the ’813 patent are pending. An infringement suit by Cryomedics against Keller, Inc., a Spembly distributor, is proceeding in the Eastern District of Pennsylvania, and two other Spembly distributors, Elmed and Storz, have brought separate actions in this District seeking declaratory judgments that the ’813 patent is void and not infringed.
. Spembly had claimed initially that no statute or rule purported to authorize service on it. That claim was withdrawn at oral argument.
.
International Shoe
applied the due process clause of the Fourteenth Amendment in determining the limits of state court
in personam
jurisdiction over non-residents. Because subject-matter jurisdiction in the present action is conferred by federal law, the sufficiency of Spembly’s contacts, whether with the State of Connecticut or with the United States, must be tested against the Fifth Amendment. Although the Fifth Amendment test is sometimes expressed in more general “fairness” terms,
International Shoe
and subsequent cases provide the basis for the fairness test, and the analysis is substantially similar.
E. g., Honeywell, Inc.
v.
Metz Apparatewerke,
. Spembly concedes that vеnue is properly in this District, 28 U.S.C. § 1391(d).
See Brunette Mach. Wks.
v.
Kockum Industries,
. The complaint contains more substantial allegations of Spembly’s contacts with the United States as a whole. It alleges, for example, that Spembly provides technical assistance to its distributors and the ultimate users of its products in the United States, but makes no allegation that such activity has occurred in Connecticut. ¶¶ 20, 21. Similarly, Spembly is alleged to have solicited orders from and for its distributors in the United States, ¶¶ 22, 23, and to have sent employees to the United States to aid its distributors, ¶ 24.
. The complaint alleges in several places that Spembly sold its products in the United States through “agents.” Spembly, in an affidavit of its director, Hilton Thomas, denies that it had any “agents, salesmen, employees, officers or any other authorized persons transacting business” in Connecticut. ¶ 3. Cryomedics’ memorandum, in the section setting forth the facts it contends are relevant to the disposition of this motion, makes no mention of any agents of Spembly in the United States. The bare allegation contained in the complaint is insufficient to establish such a relationship, even for the purposes of this motion.
Cf. Leasco Data Processing Corp.
v.
Maxwell,
. This approach seems implicit in the Second Circuit’s opinion in
Leasco Data Processing Equipment Corp.
v.
Maxwell, supra. See also, Alco Standard Corp.
v.
Benalal,
. The confusion seems traceable to
Lone Star Package Car Co., Inc.
v.
Baltimore & O. R.,
. Spembly argues that the complaint does not allege an actual threat to sue in the United States. Paragraph 47, however, when read with ¶ 55, is adequate to allow proof of such a threat. In any event, the adequacy of the alleged controversy for purposes of the declaratory judgment action probably does not turn on the existence of the threat.
