Dunkley Co. v. Vrooman

PER CURIAM. Both parties appeal from a final decree awarding damages for infringement by the Dunkley Company of the same Vroo-man patent which was once sustained by this court. Vrooman v. Penhollow, 179 Fed. 296, 102 C. C. A. 484. The patent expired in 1914, the amount of damages is small, and no claim now made by either party seems important in its effect outside of this case. We therefore content' ourselves with stating merely our conclusions. ' 1. The specification describes a machine for topping onions, and the claims call for a machine for topping vegetables. Whether these claims rightly cover the defendant’s cherry stemmer is by no means free from doubt: but they are capable of a sufficiently broad construction, and this court thought the invention one of real merit. We are not satisfied that we should disturb the finding of infringement. [1] 2. The master awarded damages on the theory of a reasonable royalty, which he fixed at 10 per cent, of the selling price. The single instance of contract royalty which fixed this 10 per cent, rate would not of itself be a very compelling reason for fixing a reasonable royalty at [469] the same amount, since the contract also involved other elements; hut the master acted upon the whole record. The character of the machine and the nature oí the business and o£ the parties were put before him, and it appeared that, although the defendant made no profits upon the business, because most of the machines which it manufactured did not stay sold, yet about two-thirds of the selling price of each machine represented the computed gross profits on that machine. Upon such a record, the fixing of 10 per cent, as a reasonable royalty for an underlying patent has ample support. [2] 3. The fact that payment had been long delayed was one of the factors entering into the master’s fixing of a reasonable royalty as of the date of his report. Since this was true, and since interest is not ordinarily computable on damages before liquidation, there was no error in not awarding to plaintiffs interest before the date of the master’s report. The final decree might well have awarded interest after the date of the master’s report; but it did not, the interval between the report and the decree was brief, and the decree, by state statute, draws interest from its date. 4. The plaintiffs were not manufacturing cherry stemmers, and did not, during ihe life of the patent, suffer damages from the manufacturing of those machines which were sold by defendant practically on trial and returned to it by the purchasers and never paid for. Some of them were again sold, after the patent expired, but this was after a substantial rebuilding to obviate the defects of the form built during the life o f the patent. 5. The question of infringement was too doubtful to leave room for any award of extra damages on account of a willful infringement. 6. The other specific complaints by plaintiffs, as to the master’s report and decree, we think are without substantial merit. The decree will be affirmed, with interest upon the awarded damages from its date. Neither party will recover own costs in this court.
