on remand, we must discuss the facts. At least in one area we indicate rather strong impressions. It is in connection with the latter that we would point out that in the development of the defensive theory, the question of contributory infringement has been so magnified that it has obscured altogether that of inducing infringement by others. As to inducing infringement, § 271(b), we conclude that the Patentee is entitled to a reversal.
Evaluation of the evidence as to that phase requires that we consider the conduct — and its legality — on the part of the Defendant’s purchasers, the dealers. To be sure, they are not now parties. But their action bears on Defendant’s culpability. Moreover, we are freshly reminded that for contributory infringement, there must first be a direct infringement. Aro Mfg. Co. v. Convertible Top Replacement Co., 1961, 365 U.S. 336, 341, 81 S.Ct. 599, 5 L.Ed.2d 592.
We think that this record shows irresistibly that the dealers are infringing the patent. Infringement arises if one without permission (a) makes, (b) uses, or (c) sells a patented device. 35 U.S.C.A. § 271(a); and § 154. The dealer (tire service station) does that here. No one would question that if a dealer as an incipient Firestone and by his own ingenuity were to fill the empty From- '7. berg tube with compressible rubber, he is “making” a new appliance. Likewise, he would “use” it were it employed in repairing a tire in his shop. So far as the dealer is concerned, it does not matter what the source of the renewal rubber plug is. When the renewal process is complete, the thing is exactly the same as when sold by Fromberg.10
If, as would be the case here, the resulting product, that is the device, is the same as the patented one so that in appearance, form, fact and function, it is identical, it matters not how or in what manner that was brought about. 3 Walker, Patents § 453 (Deller ed. 1937). The person who does that surely infringes, if the term has any meaning at all. But civil culpability need not stop with the dealer who does the final act of making, using or selling. The prohibition of the law, now codified in § 271(b), extends to those who induce that infringement. Of course inducement has connotations of active steps knowingly taken — knowingly at least in the sense of purposeful, intentional, as distinguished from accidental or inadvertent. But with that qualifying approach, the term is as broad as the range of actions by which one in fact causes, or urges, or encourages, or aids another to infringe a patent.11

It was overwhelmingly established by expert testimony and a categorical concession by Defendant that Claims 1 and 2 of Fromberg read precisely on the refilled Fromberg tube. Infringement in fact is flagrant unless the dealer or Defendant had the legal right to refill it.

See Walker, Patents (Deller ed. 1962 Suppl.) pp. 1764-1771: “Active inducement, which is considered to be part of the judge-made doctrine of contributory infringement, involves ‘the actionable tort of knowingly aiding or abetting another to infringe a patent.’ (Note 66 Vale Law Journal 132, 1956) The enactment of Section 271(b), although ambiguous, was supposed to and has been considered to codify prior law. Hence, active inducement or contributory infringement have been generally limited to those situations where the defendant has induced someone else to infringe the plaintiff’s patent and when the defendant himself has not infringed the patent by making, using, or selling the invention. [Gould-National Batteries v. Sonotono Corp., 130 U.S.P.Q. 26; N.D.Ill. (1961).]” “The following has been adjudged infringing conduct: licensing others to use infringing machines and processes ; fitting machinery for operation at the purchaser’s plant; converting machinery or adjusting operating parts ; passing on information intending to bring about infringement, (Jones v. Radio Corp. of America, 131 F.Supp. 82); furnishing drawings and granting license (Weyerhauser Timber Co. v. Bostich, D.C., 178 F.Supp. 757, accused machines, Conmar Products Corp. v. Tibony, 63 F.Supp. 372); and granting immunity from suit to an infringer * P. 1764, 1962 Supplement. The cited Jones v. RCA case gives a good *412summary of pre-1952 Code decisions as to acts inducing infringement even without sales.
