OPINION
Now pending before the Court are the third-party defendants’ motions to dis *1029 miss the third party complaint for lack of jurisdiction over the person, insufficiency of process and insufficiency of service of process. A brief statement of the background of this litigation is necessary to our disposition of the motions.
The plaintiffs filed their respective complaints in diversity actions for personal injuries and in the case of The Marley Company for property and consequential damages they sustained when a Pignon Crane collapsed at a construction site near the Village of Huff, Indiana County, Pennsylvania. Relying upon the theory of strict liability, Restatement of Torts (2d) § 402A, the plaintiffs alleged defendant Bell, a national sales corporation engaged in selling construction cranes and similar equipment, sold a crane to The Marley Company in an unreasonably dangerous defective condition. Thereafter, Bell impleaded Societe de Construction Mecaniques du Bugey, the manufacturer of the crane, and Tichauer et Cie, the world wide sales agent who sold the crane to Bell f. o. b. Belley, France. Both third-party defendants are French enterprises not registered to do business in the Commonwealth of Pennsylvania nor did they maintain an office within the Commonwealth. Furthermore, at the time this crane was sold to Bell by Tichauer et Cie and by Bell to The Marley Company, Bell by contract with both French Corporations had the exclusive sales rights for the tower cranes in the United States of America and Puerto Rico. Motions to dismiss the impleaded defendants for lack of personal jurisdiction were filed and denied by Judge Knox with the issue certified for interlocutory appeal pursuant to 28 U.S.C. § 1292(b). The Court of Appeals accepted the appeal and after considering the evolution of the Pennsylvania “long-arm” statute
1
; judicial interpretations of the 1968 amendment thereto; the statutory requirement of “doing business” within the Commonwealth; concluded the third-party defendants conducted insufficient activities within the Commonwealth as to satisfy the statutory prerequisites for the exercise of personal jurisdiction. Consequently, it held, “the district court erred in denying appellants Societe and Tichauer’s motion to dismiss for lack of personal jurisdiction.” Gorso v. Bell Equipment Corporation,
Mindful of the Court’s comments as to service under the new “long-arm” statute, the third-party plaintiff moved and was granted leave to join Societe and Tichauer on May 21, 1973. Service of process was made by certified mail on the Secretary of the Commonwealth on June 7, 1973, and on the Department of State July 30, 1973, with service by registered mail to the third-party defendants on July 31, 1973. It is as a result of these latest events that the impleaded third-party defendants move to dismiss for lack of personal jurisdiction and sufficiency of process. The third-party defendants argue the amendments to the Pennsylvania “long-arm” statute, 2 defining in more liberal terms what constitutes doing business by foreign corporations has no retroactive effect to an action initiated against them in October *1030 1970; they aver the decision of the Court of Appeals unappealed from constitutes the law of the case; next they maintain if the amended long-arm statute were applied to them, it would be an unconstitutional denial of due process because of their minimum business contacts with the Commonwealth of Pennsylvania; and lastly, they claim the amended long-arm statute is unconstitutional as enacted because of a distinction made between non-qualified foreign corporations and non-resident individuals in that the amendments apply to the latter class only on or after August 30, 1970.
In Benn v. Linden Crane Company,
We see little, if any, distinction between the situation in
Benn
and the instant case of an impleaded third-party defendant foreign corporation. We are in agreement with the Court in
Benn
that the new Pennsylvania “long-arm” statute is procedural and conclude that it governs the validity of the re-service as it was the law in effect at the time re-service was made. To the persuasive and well-reasoned opinion in
Benn,
we would add only the following observations of the Pennsylvania Supreme Court in Myers v. Mooney Aircraft, Inc.,
“Statutes which are designed to change the mode of judicial procedure, where such change relates to the method of enforcing a right and does not affect the right itself, are construed to apply to causes of action which accrued before enactment as well as to those to accrue thereafter.”;
and, in Wenzel v. Morris Dist. Co., Inc.,
“This Court has long since recognized that ‘[t]he purpose of the Act * * * [the Business Corporation Law] is to bring foreign corporations doing business in this State within the reach of legal process. The act is for the protection of those with whom such corporations do business or to whom they may incur liabilities by their wrongful acts.’ [Citation omitted] Moreover, * * * the legislature, by successive amendments to the Business Corporation Law, has greatly extended the jurisdiction of the courts of this Commonwealth over non-registered foreign corporations.”
We turn to the contention that the unappealed decision of the Court of Appeals in Gorso v. Bell Equipment Corporation, supra, constitutes the law of the case and therefore is finally dispositive of the issue of in personam jurisdiction over the third-party defendants. Although this theory is raised in their brief, the third-party defendants cite no cases supporting its applicability to this case in its present factual setting. The third-party plaintiff, on the other hand, argues the principle of law is not applicable for the appellate court construed the procedural law in effect at the time the first service of process was made. We agree with the third-party plaintiff that the Court of Appeals did not rule upon the validity of the service of process under the new statute, the constitutional efficacy of the same, if made, nor *1031 upon the retroactive versus prospective application of the statute. 3 Thus even if the doctrine is applicable in this area of the law, it would not come to play under the present factual setting in view of the fact that the Court of Appeals has not ruled on the issue now pending before this Court.
We consider next the third-party defendants’ argument against subjecting them to in personam jurisdiction. Although counsel for the third-party defendants admits having stipulated the third-party defendants are unregistered French corporations, he is not satisfied such is their current status and states in his brief
4
he hopes to have a reply in time for oral argument on his motion. No further explanation has been provided. Consequently, we shall rely upon the stipulated fact that the third-party defendants are unregistered foreign corporations. Since the Court of Appeals held that the third-party defendants were not “doing business” within the Commonwealth under the terms of § 2011(C), the former “long-arm” statute, we must determine if the new statute commands a different result. In this connection, it is beyond dispute that the following acts of the third-party defendants occurred in the Commonwealth; (1) the delivery of spare parts into Pennsylvania approximately in time to the collapse of the crane; and, (2) the tortious act of the third-party defendants within Pennsylvania, namely, the collapse of the crane allegedly due to defects in design or manufacture.
5
As previously mentioned, the Court in
Gorso
held these acts insufficient to satisfy the statutory prerequisites
6
for the exercise of personal jurisdiction by state courts in the absence of a prior in-state sale. Under the former “long-arm” statute, the Court concluded the direct or indirect shipment of merchandise into the state did not alone constitute “doing business” without the showing of systematic or continuous conduct. However, under the new “long-arm” statute, 42 Pa. S. § 8309(a) (3),
7
the direct or indirect shipment of merchandise into the Commonwealth constitutes “doing business” for the purpose of service of process upon nonqualified foreign corporations and the exercise of in personam jurisdiction over them in the Courts of the Commonwealth. The Court in Aquarium Pharm., Inc. v. Industrial Press. & Pack., Inc.,
*1032 It is clear to us that the third-party defendants had shipped merchandise into this Commonwealth. Therefore, it is our opinion they were “doing business” under § '8309(a)(3) which permits substituted service upon the Department of State, and such service once made on the third-party defendants, clothes this Court with jurisdiction over the instant case. We believe our decision on this issue is consistent with the clear intention of the legislature as is evidenced by the recent amendment 9 expressing the public policy of Pennsylvania that the jurisdiction and venue of courts of the Commonwealth shall extend to all foreign corporations to the fullest extent allowed under the Constitution of the United States.
Remaining for consideration are the constitutional due process and equal protection attacks upon the new “long-arm” statute. We believe the due process argument under the test of International Shoe Co. v. Washington,
The equal protection argument is without merit since all nonqualifying foreign corporations are treated alike. Equal protection and its guaranty of like treatment permits classification which is reasonable and which is based upon differences having a reasonable relation to the object or purpose dealt with or to.the public purpose sought to be achieved by the legislation involved. The equal protection clause does not forbid discrimination with respect to things that are different. Puget Sound Co. v. Seattle,
For the foregoing reasons, the third-party defendants’ motions to dismiss shall be denied. Furthermore, since service has been made by serving the Department of State with copies by registered mail to the third-party defendants, there can be no question of the sufficiency of service of process. 11
An appropriate order shall be entered.
