Plaintiff’s appeal from the district court’s dismissal of its patent infringement suit for improper venue raises the question: Whether defendant’s activities, in the Northern District of Illinois, Eastern Division, amounted to “acts of infringement” of plaintiff’s patent. 1 We disagree with the district court’s negative answer to the question.
Since defendant concedes that it has a regular and established place of business within the district, venue will lie if defendant, a non-resident of the district, has infringed plaintiff’s patent by selling or using the accused device within the district. 2
The complaint alleges defendant’s infringement by “making and selling” the accused “lading separating devices” covered by plaintiff's patent. 3 Defendant’s motion to dismiss asserted that it had committed no act of infringement “within this district” and that venue was accordingly improper.
Orders for the accused device were solicited in the district as part of a continual sales effort, and literature describing the device was distributed in the district to promote sales, but orders were immediately forwarded to defendant’s home office in Michigan for approval. There is no evidence in the record of any sales or deliveries made in the district. 4 On one occasion Veague, defendant’s Chicago sales manager, took representatives of the Santa Fe Railroad and the Jewel Tea Company, prospective customers, to a Southern Pacific freight car, located within the district, which was equipped with the accused device. There he demonstrated the operation of the device, with the car both loaded and empty.
Plaintiff contends that these demonstrations by Veague for the purpose of making a sale constituted an infringing “use” and therefore satisfied the venue statute. 5 It also urges the “broader proposition” that defendant’s systematic and continuous solicitation of orders for the accused device from a regular and established place of business in the district, in and of itself, is sufficient to sat *951 isfy the venue requirement. We think the true rule in the case at bar is that the systematic and continuous solicitation plus the two demonstrations is sufficient to establish venue on the basis of plaintiff’s allegation of selling.
A mistaken reliance on the decision of the Supreme Court in W. S. Tyler Co. v. Ludlow-Saylor Wire Co.,
This has resulted in a rather strained interpretation of infringing “use.”
In the case at bar plaintiff charges “selling” and presumably will offer proof of “sale” at trial and not proof of “use.” The demonstrations are proper proof of “sale” and not proof of “use” because in them the accused article was not used for the purpose for which it was intended. Its intended use was to divide loads in freight cars, not for demonstration to intended customers. We believe it is illogical to lay venue on “use” where proof is to be of a “sale” and we prefer, not to nourish that procedure.
In W. S. Tyler Co. v. Ludlow-Saylor Wire Co.,
“But when the commission of an act of infringement is essential to jurisdiction, the completed act must be proved. There must be proof either of a manufacture, a use, or a sale within the district, contracts to manufacture, threats to use, negotiations for a sale, will not be sufficient, for the reason that the statute requires proof of the completed act.”116 F. at 641 .
The necessity for a “completed sale” or a “completed act of infringement” had
*952
the apparent approval of the Second Circuit in Bulldog Elec. Prod. Co. v. Cole Elec. Prod. Co.,
We do not think the dicta in Tyler, Bulldog, and Endrezze compels us to decide that a completed sale was necessary for a finding of venue. The “completed sale” notion derived from the formulation of a rule, without authority cited, by a single judge of the old circuit court of the Southern District of New York. We think the Fourth Circuit’s reliance on that rule weakens its decision in Dow Chemical that a “completed act” of infringement is necessary to establish venue; and that we are not impelled to decide that a “completed sale,” in the case before us, is necessary for venue purposes.
The Second Circuit, despite its earlier apparent approval of Judge Lacombe’s rule, noted in Kaz Mfg. Co. v. Chesebrough-Ponds, Inc.,
We think the test is likewise léssstrict in determining, for venue purposes;, whether defendant’s acts of selling-amounted to a “sale.” Technically the-sales solicited by defendant were not; completed within this district, Minnesota Mining & Mfg. Co. v. International Plastic Corp.,
We hold that the two demonstrations of the accused device, added to the systematic and continuous solicitation of' orders within the district, constitute, for venue purposes, a sufficient degree of' selling to amount to “infringing sales.”'
We do not reach plaintiff’s “broader proposition” that mere solicitation as-part of a systematic and continuous sales-effort is sufficient for venue purposes.. We need not discuss, therefore, James. P. Marsh Corp. v. United States Gauge Co.,
Finally, defendant contends that sex*vice of process was insufficient since it was made on Veague’s secretary at defendant’s Chicago office. Since Veague was out of the office 75 to 80 per cent. *953 • of the time, and since notice of the summons was communicated immediately, at Veague’s direction, to defendant at its home office, the service was sufficient. 10
The judgment is reversed and the cause remanded for further proceeding •consistent with this opinion.
Notes
. Venue in patent infringement suits is governed solely by 28 U.S.C. § 1400(b), Fourco Glass Co. v. Transmirra Prod. Corp.,
Infringement is defined by § 271(a) of the Patent Act: “ * * * whoever without authority makes, uses or sells any patented invention, within the United States * * * infringes the patent.” 66 Stat. 811 (1952), 35 U.S.C. § 271(a) (1954).

. After judgment the district court denied plaintiff’s motion under Pule 75(h), Fed. R.Civ.P., to add a number of “papers” to the record which would have shown delivery of the accused device to a customer within the district. We must act upon the record as it was at the time the court ruled, and cannot consider these “papers” in determining whether the court’s ruling was erroneous. Dempsey v. Guaranty Trust Co.,
