Opinion

MEMORANDUM

DOOLING, District Judge.

Plaintiff sued for infringement of its Nichols and Garshelis patent, U. S. Patent No. 2,878,514, on an apparatus for curling plastic yarns—such as cellulose acetate yarn or polyvinylidine chloride yarn (“Saran”)—to be used as hair on a doll’s head. Defendant denied infringement, counterclaimed for a declaration of invalidity, and charged plaintiff with abuse of the patent, unfair competition in sending threatening letters to alleged infringers and contributory infringers, and violation of the antitrust laws in connection with a series of annual contracts under which Celanese Corporation agreed not to sell any 600 denier, 13 filament, fire-resistant yarn, peculiarly suited for doll’s hair, to anyone except to plaintiff. It has been concluded that the defendant’s device infringed three claims of plaintiff’s patent but that the patent is invalid under 35 U.S.C.A. § 103; it has been concluded further that there is no merit in defendant’s countercharges of patent abuse, unfair competition and violation of the antitrust laws. Findings of fact and conclusions of law have been separately made.

Historically, doll’s hair was made up in wigs which were then glued to the doll-head. When vinyl dolls’ heads came into use in the 1950s, it became possible to “root” simulated hair directly in the vinyl heads by use of rooting machines. Pre-curled hair was served to the rooting machines from bobbins or “quills” on which the plastic yarn, simulative of hair, had been permanently curled by heating or wetting. Many inconveniences and cost elements attended winding the bobbins, imparting the curl, storing an inventory of “hairs” of various colors on bobbins, and trying to attain long production runs of curled yam feeding to the rooting machines from bobbins that could not carry much yarn and could not readily be tied head to tail to lengthen the yarn runs. To overcome these shortcomings the patentees developed their curl making device, and a method of quick-curling the yarn while it passed along the mandrel of their curl making device; the patentees’ original application embraced both concepts and it was divided; the patentees obtained two patents, the one in suit on the curl-forming apparatus (No. 2,878,514) and one on the permanent curling method (No. 3,054,015); the latter patent is not involved in this case.

The device of plaintiff’s patent No. 2,878,514 forms curls by whirling a hollow tube, through which the yarn passes, around a tapered mandrel. As a loop of curl is whirled around the tapered mandrel, it snares on the mandrel and slides down the mandrel slope in a tightening noose, pushing the next previous loop of curl ahead of it and being pushed by the next loop of curl that is snared on the taper of the mandrel. The patentees’ work consisted in organizing familiar machine elements to make the procedure operative. They had to lead the yarn securely and controllably to the point where it could be—in effect—discharged from an eyelet, or a tube end, or some other device that would be whirled around the taper of a mandrel; and they had to support the tapered mandrel in mid-air, as it were, since turns of yarn had to loop continuously around it and pass along its length until removed as completed curls.

They solved the first problem by using to transport the yarn a hollow rotating shaft enlarged at one end into a collar, [975]*975mounting the hollow shaft on bearings, and providing belt means for rotating the shaft; through the collar they drilled an escape passage for the yarn, making an angle of about 45° with the shaft, connecting the inside of the shaft with the outside. In the drilled passage they fitted a tube which, when it reached the outside of the collar, was bent and led forward parallel to the shaft and some distance beyond the end of the collar. They thus had a path—the hollow shaft —along which they could securely lead the yarn, and an exit passageway—the tube—through which the yarn could be lead out for whirling around the shaft in a circle considerably wider than the circumference of the shaft or the collar.

The patentees solved the second problem by mounting the wide end of the tapered mandrel on a bearing that rode on the end of the hollow rotating shaft; the mandrel was bent at right angles beyond the end of its taper, and its hanging segment served to prevent the turning moment, applied to the mandrel through the bearing by the spin of the rotating shaft, from spinning the mandrel.

In operation, the device is self-feeding, forms the curls automatically, and progresses them along the tapering mandrel steadily, in uniform sized loops of curl. The centrifugal force of the spin of the shaft and angled tube “throws" the yarn forward and, as it winds on the tapered mandrel, the yarn continues to move forward, evenly; no other force but the spin of the shaft and tube is required to draw the yarn from the feed cone and to keep the curls forming.

The device was eminently satisfactory. It could produce curls continuously and they could be packaged, stored and sold without any bobbins and, as a practical matter, in almost any length. The curl forming machine was a high-speed machine. While the record is meagre on the point, the device appears to have had commercial success. Plaintiff uses about one hundred in its own operation. Plaintiff also leases the devices to seven or eight other firms, who produce a substantial volume of doll-wig curls, but the terms of the leases have not been shown.

Defendant confronts plaintiff with three patents, none of which was cited in the course of the patent prosecution. Two of the patents, those to Faris, No. 2,475,019 and to Rhodes, No. 2,432,935, disclose that the concept of the self-feeding, self-progressing curl forming process achieved through use of a spinning feed to a stationary tapered mandrel was known in the textile and yarn winding field before the plaintiff’s patentees made their invention. Neither Faris nor Rhodes used a hollow rotary shaft and angled tube to transport the yarn, but both used stationary tapered mandrels and a spinner or flyer element that whirled the yarn around the stationary mandrel. Neither patent disclosed a complete anticipation of plaintiff’s patent, nor do they in aggregate completely anticipate plaintiff’s patent. Indeed, even if Whittum, No. 2,700,514, the third patent cited, is added, there is no complete anticipation: Whittum is, moreover, only doubtfully available; it is from the wire-drawing field, and it deals with coiling wire; it plainly presents a hollow rotating shaft and an angled delivery of the wire through two sheaves to a mildly tapered frame block; but Whittum is almost certainly not self-feeding, it is unlikely that its pair of open sheaves would be adequate to transport yarn, and the tapers of its frame block are not certainly curl-forming in any significant sense. But while Faris and Rhodes do not completely anticipate, they leave nothing to plaintiff’s patentees that is patentable.

The co-inventor Garshelis considered that the improvements of the device of the patent lay, first, in leading the yarn almost along the axis of rotation and then extending it through a spinning tube to lead it a small distance away from the axis in order to wind it on the conical member (the mandrel), minimizing the breaking and back-winding of yarn when the machine stopped, and, second, in combining two differently tapered conical sections in the mandrel [976]*976at the intersection of which the curl would be formed. If the second point is valid, Rhodes, No. 2,432,935, specifically-disclosed it.
