4 F.2d 510 | 6th Cir. | 1925
The Gear-Grinding Machine Company brought an action against the Studebaker Corporation for the infringement of the Ward & Taylor patent, No. 1,104,589, for improvements in gear-grinding machines, and for infringement of the Ward patent, No. 1,155,532, for improvements in trimming mechanism for grinder wheels of shaft-grinding machines. The District Court held both patents invalid, so far as sued upon, and entered a decree for defendant. This court reversed that decree and remanded the cause for an acounting.
The master found that it was impossible to determine with reasonable certainty either the profits made by the defendant in the use of the infringing device or the extent of the plaintiff’s damages; that 15 cents was a reasonable royalty on each of the 323,423 shafts manufactured by the defendant, and upon this basis awarded to the plaintiff $48,522.45, with interest thereon •from June 15, 1921, at 5 per cent, per annum, the statutory rate in Michigan. The District Court overruled the exceptions taken by both plaintiff and defendant to this finding of the master and approved the same. Both parties have appealed.
The nature of these patents, the claims in suit, and the finding of this court as to validity and infringement are all fully discussed in the opinion in the first appeal (270 F. 934), and will not be repeated here, except in so far as may be necessary. Claims 3, 7, and 8 of the Ward & Taylor patent were held valid and infringed by plaintiff’s first practice, which continued from Sep tern
Upon a careful examination of all the evidence introduced on the hearing before the master touching the question of defendant’s profits and the damages of the plaintiff, this court has reached the conclusion that it is impossible to determine with any reasonable degree of certainty the actual profits, and the ease is not one that would justify awarding all profits upon the theory of confusion, nor docs the evidence present a ease suitable for the awarding of damages as distinct from profits. For these reasons this court is of the opinion that this case is a proper one for the application of the rule of reasonable royalties. K. W. Ignition Co. et al. v. Temeo Electric Motor Co. et al., 283 F. 873, 877, and eases there cited.
Nor is it seriously contended on the part of the plaintiff appellant that this is not a proper case for reasonable royalty. When the master inquired of counsel if he had any objection to invoking or seeking to recover under the reasonable royalty basis, he replied: “No, your honor. * * * I propose to do that thing in turn. My present plan is to provide three strings to my bow, if possible. * * * One is the profits which defendants made; the other, the damages which we actually sustained; the third, what would be a reasonable royalty to pay.”
There was evidence offered on the part of the plaintiff appellant that the Hudson- Company agreed in writing to pay 25 cents royalty, but it further appears that this amount of royalty also included a settlement of all claims for damages for prior infringement. Evidence was also offered tending to prove that the Northway Motor Company agreed to pay 17 cents royalty on each splined shaft manufactured by it, but this contract also included a further cash payment in settlement of threatened litigation. It is claimed on the part of the appellant that the North-way contract, although calling for 17 cents royalty, is in fact a contract to pay 25 cents royalty, for the reason that the appellant took over certain machines that wore of much greater value than the price fixed in the settlement and royalty contract. The parties having agreed upon the value of these machines, the appellant is hardly in position to dispute that value. If permitted to do so, it would not be of controlling importance in determining the amount of royalty to be paid by the Northway Company, for the reason the shafts that may be manufactured under this royalty contract may be so large in number as to make the value of the machines taken over by the appellant of little or no importance. In fact, the estimated production for nine months was 26,500 shafts. The defendant offered substantial evidence tending to prove that the cost, on the piece price plan then in force in its factory, was identical when the gear and trimming devices were used in combination under its first practice, which was held to be an infringement of both the Ward & Taylor and the Ward patents, and when used separately, as in its second and third practices, which infringed only claim 7 of the Ward patent.
It further appears from the evidence of the plaintiff that the use of the Ward trimming device, separate and apart from the gear-grinding device, under the second and third practico of the defendant, required but a fraction of a minute for each shaft, and was. therefore a very inconsiderable part of the manufacturing cost. Upon a consideration of all of this evidence, this court would not be justified in reversing the finding of the master, confirmed and approved by the trial court.
The use of these patents enable the defendants to make splined shafts. The patents, therefore, necessarily include the process and the product. The theoretical license for which this reasonable royalty is allowed includes not only the right to make these shafts under the patents in suit, but also includes the right to use any other patent belonging to the plaintiff and necessarily involved in their production, even though not then issued. This, however, does not mean that the reasonable royalty fixed in this case would necessarily be a measure covering all the aspects of any splined shaft patent feature, but must be confined to these patents as they were here used, and where the claim for royalty arises as it does in this case. Nor does it mean that a reasonable royalty would necessarily be the same for future infringement of these a.nd later patents, but, on the contrary, that this finding as to reasonable royalty applies solely to the facts of this
For the reasons stated, the judgment of the District Court is affirmed.
