HAYNSWORTH, Circuit Judge.

We are concerned with chicken feathers and their removal during the processing of poultry for marketing. Patents covering an apparatus and a method for removal of the feathers were held by the District Court to be invalid for obviousness in the light of paper patents in other fields.1 We think the credit the District Court gave the work of the patentee was less than its due.

Background

Hunt patent No. 2,300,157 issued in 1942 upon an application filed November 16, 1939, covering the first practical apparatus for plucking poultry feathers. It consisted of a rotatable drum in which rows of protruding, flexible fingers were mounted. On most of the exposed portion of these fingers, usually made of rubber, are a series of projections or corrugations having an appearance similar to screw threads, and there is a terminal flange of larger dimension than the other projections. When the device is rotated so that the protruding fingers will strike the scalded carcass of a bird, the terminal flange and the thread-like projections frictionally engage and remove the feathers across which the flexible fingers are drawn by rotation of the drum in which they are mounted.

In its simplest form, the Hunt machine is operated without other apparatus. An operator must hold in his hands a scalded bird so that it may be struck by the fingers of the rotating drum. The operator must turn each bird over and around so that each portion of the bird is presented to the defeathering fingers. Nevertheless, use of the Hunt device in this manner was much easier and faster than hand plucking.

Validity of the Hunt patent was upheld in Hunt v. Armour & Co., 7 Cir., 185 F.2d 722.

The Hunt device was also used in a so-called automatic form. A pair of them were so placed that the defeathering fingers of each drum would strike opposite sides of a bird drawn between them. Birds were suspended by their feet from shackles attached to a conveyor which drew them between the pair of defeathering devices.

The Claimed Invention

The Hunt devices had been in wide use for a number of years when, in 1951, A. J. Toti conceived the idea of encasing a rotating drum with Hunt's defeathering fingers in an outer, rotatable shell. When scalded carcasses of birds are placed in the Toti machine, the outer shell keeps the birds in position to be struck by the fingers, partially retards the motion imparted to the birds by the force of the fingers and causes the birds to be tumbled about so that all of their parts are presented to the fingers and are defeathered. Birds thrown loosely into the machine at the top may be automatically discharged, defeathered, at the bottom.

On September 7, 1951, Toti filed a patent application containing both apparatus and method claims. The Patent Office required a division of the method and apparatus claims. Thereafter two patents issued, one No. 2,754,539 on July 17, 1956 containing method claims and the other No. 2,805,443, on September 10, 1957, containing apparatus claims. For our purposes, claim No. 1 of the No. 2,805,443 patent is sufficiently descriptive of the claimed invention.2

Toti assigned the patents to the plaintiff, Honolulu Oil Corporation, which licensed the plaintiff, Barker Poultry Equipment Co., to manufacture and sell the patented machine.

Barker's commercial machine known as the Barker Cyclomatic Picker,3 clearly embodies the principles of the Toti patent. Before it was placed in production, the machine was re-engineered by Barker, for Toti lacked facilities for such purposes and there are superficial differences in the appearance of the commercial machine and the relatively crude machine represented by the patent drawings. Such differences are to be expected when the inventor has no engineering staff, and it does not follow that the excellence of the performance of the commercial machine and its commercial success are attributable solely to Barker's good engineering. The machines are a commercial embodiment of the invention and covered by claims of the patent. Since the patent discloses all of the essential functions of the commercial machine, it is not necessary that it also disclose all of the refinements of the production model.4

The defendant goes to considerable effort to disparage the Toti machine to deny to it the advantage of the success and performance of Barker's commercial models. This it undertakes to do on the basis of a demonstration of a machine made in exact conformity with drawings of the Toti patent. Three scalded chickens were placed in the machine; the machine was operated for forty-five seconds while the District Judge and counsel observed its operation, after which the three defeathered chickens were removed.5 The defendants then argue that if it took forty-five seconds to process three chickens, the production capacity of this machine would be no more than two hundred an hour, a rate Hunt claimed in his patent for his machine.

There is nothing to support such a contention. The testimony shows that three chickens were used for the demonstration of each machine in order that the court and the other observers might better see how each operated. There is no evidence that the capacity of the machine was only three birds. There is affirmative evidence that the commercial model of Pickwick's machine had a much larger capacity, but it, too, took forty-five seconds to defeather the three birds placed in it. The demonstration furnished no basis for the computation of production rates.

The defendants concede that production models of the patented machine can defeather 1250 to 1500 birds an hour. There is testimony that the fully automatic machine can process 4,500 pounds of poultry an hour. There is no evidence that such high production rates are attributable to anything other than a workman-like application of the disclosures of the patent. The fact that the disclosures of the patent are practiced efficiently does not degrade the disclosures.
