p. 522evidence. The decretal order to account mentioned it in terms. The evidence taken by the master under the order of reference related only to attachments sold by the defeudants after the second reissue was granted. In the exceptions taken by them to the master’s report no intimation was made that the rights of the complainants under the reissue No. 3665 were not on trial, and not even when the final decree was made was it suggested that the parties had been trying the case on an issue not made by the pleadings.
After the final decree had been made, the complainants applied to have the bill of complaint amended by inserting in it a declaration on the reissued letters-patent which were decreed, to be valid, and the court below made an order containing a recitation of alleged facts to authorize the order amending the bill as prayed for.
There was no allegation that the bill of complaint ever contained the allegation as to reissue No. 3665, prior to the judgment. The motion and the order were not made “ to conform the bill to the proofs.”
Both parties appealed; the complainants because of the confirmation of the report in the face pf their two exceptions to it; the defendants because of the amendment allowed in the bill after a final decree made.
Mr. F. H. Betts, for the complainants below:
1. No part of the general expenses are justly allowable to the defendants.The method of computation of profits was erroneous. It forgot that the patent is not for the tremolo itself, but for the combination of the organ and tremolo.If an extra price is received for the combination, without any additional expense being incurred, the whole of that extra price is obtained by the addition of the combination.It does not avail the defendants to charge a portion of their general expenses against the tremolo, one member of the combination, for in so doing they take off the exact amount from the other member, the organ. The profit on the whole combination is still equal to the exact amount by
p. 523which the extra price received by reason of the making of the addition exceeds the amount received for the orgau alone. This, for example,is expressed in figures thus:Cost of organ, $100; received for organ, $200. Cost of tremolo, $12.50; received for tremolo, $25. Amount of general expenses apportioned to each organ, $50; no additional amount incurred by reason of tremolo.If all, $50 is charged against organ alone. Profit on tremolo alone is $12.50. If $45 is charged on organ and $5 on tremolo, we still have $12.50 as the profit received for the combination; i. e., $7.50 on tremolo itself and $5 on organ, by reason of adding tremolo.The same result follows from any apportionment.Any other rule than this would enable an infringer to add patented devices to his instrument, charge extra prices for them, and thereby increase his profit on his instruments by the exact amount of the proportion of his general expenses that his sales of the infringing device bear to his general business. In other words, the more he infringes the more of the general expenses he diverts from the main instrument, and thereby the more profits he makes without being accountable for it.The true rule is, if the infringing devices are an integral part of the whole instrument, without which it is incapable of use, and for which a single charge is made, then in determining profits on a part of the organization general expenses are to be apportioned according to cost, or by some other equitable rule.But when the infringing device is an optional one, used or not, at pleasure, and an extra price is charged and received for it'when used, the true profit made is the extra sum received for the addition, only such expenses being allowed as are incurred by reason of the addition.It may be urged that as the tremolos induced the sale of organs, and as the sale of organs involved expense, therefore the tremolo must bear its proportion of such expense. This is a plausible position, but in this case the sales of oi’gans produced a profit beyond the profit of the tremolo.
p. 525into the account any portion of said sums, because said defendants did not prove what part, if any, of said expenses were allowable ■under the order of reference.”If a proportion of the general expenses are to be deducted, then the defendants must bring themselves within the order, and, in regard to that order, the following things are to be noted:1. A division of expenses is to be made into “general” and “particular.”The “general” expenses being those incurred for all goods alike, such as rent, clerk hire, general advertising, &c., the particular expenses being those caused by certain particular goods, and not by reason of selling all the goods, such as cartage on particular instruments, commission of particular sales, &c.2. The burden of distinguishing between these two classes is upon the defendants. To them alone were the facts known, and it was just and proper that they, and not the complainants, should be required to prove them.The defendants, by the order, were to be “permitted” to prove their “general” expenses, as distinguished from the particular ones. Unless they showed, therefore, what their “general” expenses were as distinguished from “particular’’ ones, the master, had nothing to do but to report as before.The defendants show generally that they had incurred certain items of expense, i. e., stationery, printing, telegraphing, expressage, labor, &e.Now, each and all of these items may be items of general expense, or they may be particular expense, or they may be part one and part the other.The defendants have failed to show what part of these expenses is “general” and what part “particular;” they have failed to do this, and therefore the items should be disallowed.8. The amendment even after final decree ivas properly made.It is perfectly plain from the statement of the case that all parties, complainants, defendants, and court proceeded upon an assumption that the bill was founded on the re
p. 527Even if it were.urged that the defendants did litigate the patent No. 3665 on its merits, and were not prejudiced by the amendment, the answer is that the record shows no such state of facts. All the proofs taken by the defendants applied to the reissue No. 3444.The defendants were not required to object to the introduction of reissue No. 3665. By their answer they required the plaintiffs to prove their title to reissue No. 3444, and when the plaintiffs put in evidence the reissue No. 3665, it proved the defendants’ case for them, because it recited on its face that reissue No. 3444 had been surrendered.delivered the opinion of the court.
We think that the order of the court directing that the record be amended by inserting in the bill an averment of the second reissue was properly made, under the circumstances of the case, though made after the final decree. For practically the rights of the complainants under the second reissue, and the defendants’ infringement thereof were in issue under the auswer and the replication. The amendment deprived the defendants of no rights which they had not enjoyed during all the progress of the trial. It may well be denominated only an amendment of form, because it introduced no other cause of action than that which had been tried. It is true that an amendment which changes the character of the bill ought not generally to be allowed after a case has been set for a hearing, and still less after it has been heard. The reason is that the answer may become inapplicable if such an amendment be permitted. But in this case the defendants were uot prejudiced. They had every advantage they could have had, if the bill had originally averred the second reissue. The case is undoubtedly anomalous, but we think justice would not be subserved by denying to the Circuit Court the power to order such an amendment as was made, after the cause was tried precisely as it must have been tried if the bill had originally contained the averment inserted by the amendment.
We come then to the errors assigned by the complainants.
p. 528They relate to the estimate of profits reported by the master aud confirmed by the court. The defendants were vendors of musical instruments, including organs and melodeons, which they purchased from the manufacturers. Some of these instruments contained the tremolo attachment, and others did not. For those containing such attachments they paid an additional price and they sold them also for an increased price. In the ascertainment of the profits made by them from the sales, they wrere allowed to prove the general expenses of their business incurred in effecting the sales of all musical instruments, and deduct a ratable proportion from the profits made by the sale of tremolo attachments. It is of this allowance the complainants now complain. It is said the patent infringed was not for the tremolo itself, but for the combination of the organ and tremolo, and it is argued that if the defendants obtained an extra price for the organ combined with the tremolo without incurring any additional expense, the whole of that extra price was obtained from the addition of the combination. And it is further insisted that the true rule in cases like the present is that if the infringing device is an integral part of the whole instrument, without which it is incapable of use, and for which a single charge is made, then in ascertaining profits on a part of the organization general expenses are to be apportioned according to the cost, or by some other equitable rule. But when the infringing device is an optional one, used or not at pleasure, aud an extra price is charged and received for it when used, the true profit made is the extra sum received for the addition, deducting only such expenses as are incurred by reason of the addition. We think such a l'ule, even if it may sometimes be just, is inapplicable to the present case. We cannot see why the general expenses incurred by the defendants in carrying on their business, such expenses as store rent, clerk hire, fuel, gas, porterage, &c., do not concern one part of their business as much as another. It may be said that the selling a tremolo attachment did not add to their expenses, aud therefore that no part of those expenses should be deducted from the price obtaiued for
p. 529such an attachment. This is, however, but a partial view. The store rent, the clerk hire, &c., may, it is true, have been the same, if that single attachment had never been bought or sold. So it is true that the general expenses of their business would have been the same, if instead of buying and selling one hundred organs, they had bought and sold only ninety-nine. But will it be contended that because buying and selling an additional organ involved no increase of the general expenses, the price obtained for that organ above the price paid was all profit? Can any part of the whole number sold be singled out as justly chargeable with all the expenses of the business ? Assuredly no. The orgau with a tremolo attachment is a single piece of mechanism, though composed of many parts. It was bought and sold as a whole by the defendants. It maj' be said the general expenses of the business would have been the same if any one of these parts had been absent from the instrument sold. If, therefore, iu estimating profits, every part is not chargeable with a proportionate share of the expenses, no part can be. But such a result would be an injustice that no one would defend. We think it very plain, therefore, that there was no error in the rule adopted for the ascertainment of the profits made by the defendants out of their infringement of the complainants’ patent.
We think also the master’s report, confirmed by the court, was correct in its ascertainment,of the general expenses. At least there is nothing before us to show that it did not conform to the second decretal order. The defendants submitted analyses of their books, from which it is to be presumed the master distinguished general from particular expenses.
It follows that neither the appeal of the defendants nor the cross appeal of the complainants can be sustained.
Decree aeeirmed ; the costs of each appeal to be paid by the appellants.
