Appellee Beacon Enterprises, Inc. (Beacon), a New York corporation, commenced this diversity action against pro se appellant Mary Rose Menzies, a resident of California, seeking a declaratory judgment that certain of its products did not infringe Menzies’ trademarks. Personal jurisdiction over Menzies in the Southern District of New York was premised on Beacon’s allegation that Menzies “is regularly doing business within the City and State of New York” and that “a part of that business is directly related to the subject matter of the present action.” ¶ 2 Complaint. In her motion to dismiss and her answer, Menzies asserted, inter alia, that the court lacked personal jurisdiction over her in New York. Without notice to the parties, the district court treated Menzies’ pro se motion to dismiss as a motion for summary judgment, determined that it had personal jurisdiction over Menzies, and granted summary judgment on the merits for Beacon, the nonmoving party. We reverse the district court’s judgment because, at the early stage this litigation was terminated, (1) Beacon had not established the court’s personal jurisdiction over Menzies under either New York’s general jurisdictional statute, N.Y.Civ. Prac.Law § 301 (McKinney 1972), or the relevant provision of New York’s long-arm jurisdictional statute, N.Y.Civ.Prac.Law § 302(a)(1)(McKinney Supp. 1982-83), and (2) Menzies was not afforded an adequate opportunity to offer evidence in opposition to summary judgment. We remand for further proceedings on the jurisdictional question and, if necessary, on the merits.
*760 I
The facts, garnered from an undeveloped record, are stated here as they are set forth in the parties’ pleadings and at a brief hearing held on April 2,1982. Beacon markets a line of so-called “exercise and weight reducing devices,” including a garment advertised as the “Saunette Suit.” This vinyl fabric suit retains heat and moisture and, according to Beacon, “promotes weight reduction much in the way that a sauna achieves such result[s].” ¶ 5 Complaint. Menzies advertises and sells a similar garment labelled “Sauna Suit,” which, according to her advertisements, “works like a portable sauna.” Menzies apparently runs her small mail order business from her California home. She has a federally registered trademark for “Sauna Suit,” as well as for “Super-Sauna” and “Sauna Girdle,” other weight reducing garments. In addition, Menzies owns federal copyrights for the label and packaging of the “Sauna Suit,” “Super Sauna” and “Sauna Girdle.”
The present controversy arose when Menzies sent a letter dated December 11, 1981 from California to Beacon at its New York City headquarters. Menzies’ letter: (1) informed Beacon of her trademarks and copyrights in “Sauna Suit,” “Super-Sauna” and “Sauna Girdle;” (2) alleged that Beacon’s use of the mark “Saunette Suit” violated federal copyright and trademark law; and (3) threatened that “[i]f your company does not cease and desist, appropriate legal action will be taken.” Less than two weeks later, on December 23,1981, Beacon filed its complaint in the instant action. Although devoid of statutory citations, Beacon’s jurisdictional allegations apparently sought to place Menzies within the scope of both New York’s general jurisdictional statute, N.Y. Civ.Prac.Law § 301 (McKinney 1972) 1 and the relevant section of New York’s long-arm jurisdictional statute, N.Y.Civ. Prac.Law § 302(a)(1) (McKinney Supp. 1982-83). 2
(a) Acts which are the basis of jurisdiction. As to a cause of action arising from any of the acts enumerated in this section, a court may exercise personal jurisdiction over any non-domiciliary, or his executor or administrator, who in person or through an agent: 1. transacts any business within the state or contracts anywhere to supply goods or services in the state.
Beacon’s substantive claim was that Menzies “does not possess any exclusive right in or to the use of the words ‘saunette suit,’ which are the descriptive words of the language, in regard to the sale of a sauna-type weight reducing garment.” Beacon also alleged that the packaging of its “Saunette Suit” bore no resemblance to that of Menzies’ products and that Beacon’s marketing of its product did not cause confusion, mistake or deception. Beacon further claimed that Menzies’ December 11 letter created a sufficient controversy to warrant a declaration of the parties’ rights and an order enjoining Menzies from making any charges of trademark infringement against Beacon or its agents, distributors or customers.
On February 10, 1982 Menzies, pro se, filed an answer denying the primary allegations contained in the complaint. Menzies specifically denied any business activity in New York and stated, “[defendant has no manufacturing facilities, no sales offices, no advertising offices, no agents or distributors in the Southern District of New York or elsewhere in the state of New York at this time.” By her answer Menzies further asserted insufficiency of service of process, improper venue and failure to state a claim. She alleged as “affirmative defenses” that Beacon’s marketing of the “Saunette Suit” violated her trademarks and copyrights and constituted unfair competition. Although Rule 12(b) of the Federal Rules of Civil Procedure requires that a motion to dismiss be filed prior to filing of a responsive pleading, Menzies did not file her “motion to dismiss” until March 4, 1982. In that motion, she alleged lack of personal jurisdiction, improper venue, lack of subject matter *761 jurisdiction (because the $10,000 jurisdictional amount had not been met) and failure to state a claim.
On March 30, 1982 Menzies commenced a pro se action in the United States District Court for the Central District of California (the California action) against Beacon and Thrifty Corporation, a customer of Beacon. In the California action, Menzies alleged that Beacon and Thrifty were violating her federal trademarks and copyrights and engaging in unfair competition by marketing the “Saunette Suit.” Menzies sought injunctive relief and damages. Beacon responded to Menzies’ suit by filing a motion in the United States District Court for the Southern District of New York seeking an injunction against the California action.
On April 2, 1982 the New York district court held a consolidated pretrial conference and hearing on the motion to dismiss. Menzies, still appearing pro se, personally attended. On several occasions, the court asked the parties to produce samples of their products and trade dress, but Menzies had not brought any samples with her from California. 3 Menzies was able only to produce an advertising insert describing and depicting the “Sauna Suit.” Counsel for Beacon produced a packaged sample of its product.
Several times during this hearing Menzies sought to interject her jurisdictional defense. When the court finally addressed the issue, Menzies asserted that her products had been sold in New York only by mail. She also stated that Beacon was the only entity to which she had written requesting cessation of infringement. The only evidence produced by Beacon that was relevant to the issue of Menzies’ business activity in New York was her “cease and desist” letter and an unsupported statement by Beacon’s counsel that “a colleague of my client who is selling a similar product [in an unspecified location] received similar letters, and his customers received similar letters.” At the close of the hearing, the judge informed Menzies: “I have a very good understanding of what your product looks like. You have told me it is wrapped in plastic and that it has the mark printed on the outside and that it has this insert that has been marked as an exhibit here today.... I am going to take care of your case on the merits. If you don’t like the result, you may apply to the Court of Appeals.”
By an order filed April 27, 1982, the district court construed Menzies’ motion to dismiss as one for summary judgment and granted summary judgment for Beacon, the nonmoving party. The court determined that it had personal jurisdiction over Menzies because “it was apparent on the oral argument that sufficient activity takes place in New York with respect to defendant’s product.” The court further found that there was no trademark infringement by Beacon, stating: “Certainly no confusion can follow between the relatively weak mark of ‘Sauna Suit’ and the equally weak mark of ‘Saunette Suit,’ particularly where Beacon Enterprises’ name appears clearly on its own product.” Consistent with the memorandum-decision, judgment was entered (1) declaring that “a product sold as ‘Saunette Suit’ and in association with the name Beacon Enterprises is not trademark infringement of any trademarks of defendant, nor gives rise to consumer confusion with any product of defendant” and (2) enjoining Menzies from maintaining the California action.
Menzies’ timely appeal to this Court followed. 4
II
A. Personal Jurisdiction
Our examination of the record, which includes the transcript of the hearing below, compels us to reverse the district court’s finding of personal jurisdiction over
*762
Menzies. As plaintiff, Beacon bore the ultimate burden of proving the court’s jurisdiction by a preponderance of the evidence.
See Marine Midland Bank, N.A. v. Miller,
Personal jurisdiction over, a defendant in a diversity action in the United States District Court for the Southern District of New York is determined by reference to the relevant jurisdictional statutes of the State of New York.
See United States v. First National City Bank,
1. N.Y.Civ.Prac.Law § 301: “Doing Business”
Under the New York courts’ interpretation of section 301, a non-domiciliary subjects herself to personal jurisdiction in New York with respect to
any
cause of action if she is “engaged in such a continuous and systematic course of ‘doing business’ here as to warrant a finding of [her] ‘presence’ in this jurisdiction.”
Simonson v. International Bank,
There is no evidence that Menzies has ever physically appeared in New York to conduct business. The only contacts by Menzies with New York set forth in the record are (1) her “cease and desist” letter to Beacon, and (2) an unspecified number of mail order sales of her products in New
*763
York. These contacts are insufficient to satisfy section 301’s “doing business” test. The shipment of goods into New York does not
ipso facto
constitute “doing business.”
See Loria & Weinhaus, Inc. v. H.R. Kaminsky & Sons, Inc.,
Even if we are to assume that Menzies solicited those New York mail order sales by advertisements reaching New York, section 301’s jurisdictional requirements remained unsatisfied. Although “once solicitation is found in any substantial degree very little more is necessary to a conclusion of ‘doing business,’ ”
Aquascutum of London, Inc. v. S.S. American Champion,
Accumulating all of Menzies’ contacts with the forum set forth in the record, we conclude that she is at most only “occasionally” doing business in New York and is not “engaged in such a continuous and systematic course of ‘doing business’ ” in New York as to subject her to personal jurisdiction under section 301.
Cf. Liquid Carriers Corp. v. American Marine Corp.,
2. N. Y. Civ.Prac.Law § 302(a)(1)
A defendant who is not “doing business” in New York within the meaning of section 301 may be sued in New York on a lesser showing of forum contacts if the cause of action arises from those contacts. A defendant who “transacts any business within the state or contracts anywhere to supply goods or services in the state” subjects himself to personal jurisdiction under N.Y.Civ.Prac.Law § 302(a)(1) (McKinney Supp. 1982-83) in any action arising from the transaction of business or contracting to supply goods and services in New York.
See generally Galgay v. Bulletin Co.,
The New York Court of Appeals has recently observed that “[e]ssential to the maintenance of a suit against a non-domiciliary under CPLR 302 (subd [a], par. 1) is the existence of some articulable nexus between the business transacted and the cause of action sued upon .... Indeed, it is this basic requirement that differentiates the long-arm authority conferred by CPLR 302 (subd [a], par. 1) from the more traditional authority of the New York courts under CPLR 301 to exercise in personam jurisdiction over foreign defendants who are ‘present’ within the State by virtue of their ‘doing business’ here.”
McGowan v. Smith,
Beacon’s defensive declaratory judgment action is not one that the courts of New York have regularly linked to section 302(a)(1) jurisdiction. Section 302(a)(1) is typically invoked for a. cause of action against a defendant who breaches a contract with plaintiff,
see, e.g., Longines-Wittnauer Watch Co. v. Barnes & Reinecke, Inc.,
Although we have found no New York state precedent addressing the scope of section 302(a)(1) in the same circumstances as those present here, we find support for our position in Judge Lasker’s analysis of analogous facts in
Columbia Pictures Industries, Inc. v. Schneider,
Due to his doubt that plaintiff had sustained its burden of showing that the New York courts could properly exercise section 302(a)(1) personal jurisdiction over the defendants, Judge Lasker stayed the New York action pending resolution of the California lawsuit. After reviewing the purpose of section 302 and its construction by the New York state courts, Judge Lasker stated that:
[W]e doubt that a liberal construction [of N.Y.Civ.Prac.Law § 302(a)(1)] should be given where a New York domiciliary seeks to require non-domiciliaries to appear in the state to permit plaintiff to establish that it has not injured the out-of-staters; as a matter of law, it would be difficult, without clearer guidance from the state courts, to find that plaintiff’s cause of action arose out of the defendant’s within-the-state transactions.
Columbia Pictures Industries, Inc. v. Schneider,
We encounter similar difficulty finding a sufficient nexus between the present defendant’s shipment of goods to New York and plaintiff’s defensive declaratory judgment action. The New York Court of Appeals’ recent emphasis on the importance of the nexus requirement in applying section 302(a)(1),
see, e.g., McGowan v. Smith,
*766
Turning next to Menzies’ “cease and desist” letter, we may assume for present purposes that Beacon’s cause of action is based in part on this letter sent to Beacon at its New York offices. This “cease and desist” letter contributed to the creation of a sufficient controversy to warrant a declaratory judgment action.
See Chesebrough-Pond’s, Inc. v. Faberge, Inc.,
Menzies’ contact with New York is deficient in both quality and degree and thereby fails to support section 302(a)(1) jurisdiction. New York courts have consistently refused to sustain section 302(a)(1) jurisdiction solely on the basis of defendant’s communication from another locale with a party in New York.
See Katz & Son Billiard Products, Inc. v. Correale & Sons, Inc.,
Accordingly, on the present record, we conclude that Menzies’ shipment of goods into New York is not sufficiently related to Beacon’s cause of action and that Menzies’ “cease and desist” letter does not constitute a “transaction of business” within New York sufficient to support the exercise of section 302(a)(1) long-arm jurisdiction.
B. Summary Judgment on the Merits
If the district court finds personal jurisdiction over Menzies after further proceedings, further consideration of the merits will be necessary.
*767
The district court erred in failing to give prior notice to the parties before converting Menzies’ motion to dismiss into a motion for summary judgment. Menzies grounded her motion to dismiss,
inter alia,
on the defense of failure to state a claim upon which relief can be granted. Fed.R. Civ.P. 12(b)(6). On a 12(b)(6) motion, if “matters outside the pleading are presented to and not excluded by the court, the motion shall be treated as one for summary judgment and disposed of as provided in Rule 56,
and all parties shall be given reasonable opportunity to present all material made pertinent to such a motion by Rule 56.”
Fed.R.Civ.P. 12(b) (emphasis added). Rule 56 requires that the parties be given at least ten days notice of conversion of a Rule 12(b)(6) motion so that they may present relevant materials.
See
Fed.R.Civ.P. 56(c). We have strictly enforced the ten day notice rule on other occasions,
see, e.g., In re Bristol Industries Corp.,
Notice is particularly important when a party is proceeding
pro se
and may be unaware of the consequences of his failure to offer evidence bearing on triable issues.
See Madyun v. Thompson,
[B]efore entering summary judgment against [this pro se] appellant, the District Court, as a bare minimum, should have provided him with fair notice of the requirements of the summary judgment rule. We stress the need for a form of notice sufficiently understandable to one in appellant’s circumstances fairly to apprise him of what is required.
Hudson v. Hardy,
Menzies was clearly prejudiced by the failure to afford her notice. The crucial issue in determining a claim of common law trademark infringement is whether there is a “ ‘likelihood that an appreciable number of ordinarily prudent purchasers are likely to be misled, or indeed simply confused, as to the source of the goods in question.’ ”
Spring Mills, Inc. v. Ultracashmere House, Ltd.,
Ill
We remand for further proceedings on the issue of personal jurisdiction and, if necessary, on the merits. Until a full evidentiary hearing or a trial on the merits is held, Beacon need only set forth prima facie evidence of personal jurisdiction.
See Marine Midland Bank, N.A. v. Miller,
Additional procedural confusion may also have resulted from the untimeliness of Menzies’ “motion to dismiss” for lack of personal jurisdiction which was served
after
her answer. Fed.R.Civ.P. 12(b) requires that “a motion making any of these defenses shall be made before pleading if a further pleading is permitted.” However, as Menzies raised the jurisdictional defense in her answer and Beacon never objected on the grounds of untimeliness or prejudice, this minor procedural defect by a
pro se
litigant should not prevent consideration of the jurisdictional issue on remand. Judicial economy will be served by such treatment.
See Majerus v. Walk,
In reversing the judgment we also vacate the district court’s permanent injunction against litigation of the California action. The vacating of the injunction is without prejudice to Beacon’s refiling of a request for injunctive relief if personal jurisdiction over Menzies in New York is sustained.
See Factors Etc., Inc. v. Pro Arts, Inc.,
The judgment is reversed and the cause remanded for further proceedings consistent with this opinion.
Notes
. This section provides: “A court may exercise such jurisdiction over persons, property, or status as might have been exercised heretofore.”
. Section 302(a)(1) of the CPLR entitled, “Personal jurisdiction by acts of non-domiciliaries,” provides in pertinent part:
. The district court initially suggested that Menzies mail a product sample to the court from California but later informed Menzies that a sample was unnecessary.
. Menzies’ application to this Court for a stay pending appeal was denied on June 2, 1982.
. We recognize that a motion to dismiss pursuant to Fed.R.Civ.P. 12(b)(2), rather than a motion for summary judgment, Fed.R.Civ.P. 56, is the more appropriate procedural vehicle for contesting personal jurisdiction.
See Heyward v. Public Housing Administration,
. We need not decide whether the parameters of jurisdiction under section 301 are as wide for non-domiciled natural persons as they are for non-domiciled corporations. See 1 J. Weinstein, H. Korn, A. Miller, New York Civil Practice ¶ 301.15 (1983).
Compare Nilsa B.B. v. Clyde Blackwell H.,
Moreover, in the present case, it is unnecessary to determine whether the exercise of personal jurisdiction would comport with federal constitutional standards of due process,
see, e.g., World-Wide Volkswagen Corp. v. Woodson,
. In 1979 the New York Legislature amended CPLR 302(a)(1) to add the clause permitting the exercise of personal jurisdiction over a non-domiciliary who “contracts anywhere to supply goods or services in the state.” 1979 N.Y.Laws ch. 252 § 1; see
McGowan v. Smith,
