Opinion

SMITH, District Judge.

This is a suit for the alleged infringement of U. S. Patent No. 2,475,572 on an electric steam iron brought by Edward P. Schreyer, the patentee, and his exclusive licensee, Rival Manufacturing Company. The plaintiffs seek additional redress for claimed unwarranted use by defendants of certain information relating to the manufacture of the patented device disclosed in confidence during the course of negotiations looking toward the grant of a license under the patent to defendants. These negotiations were terminated without the formation of a license contract. Insofar as possible the two phases of the litigation, the patent issue and the unfair competition issue, were separately dealt with on trial and we shall so deal with them here.

I. The Patent Issue.

Schreyer’s invention on which a patent was issued on July 5, 1949 after more than seventeen months of proceedings in the Patent Office is on a new type of electric steam iron. The patent, as issued, sets forth twenty-five claims which describe in detail and with the familiar variation in phraseology the asserted novel features of the invention. Essentially the iron, which, in appearance, is not unlike the ordinary electric iron, consists of a sole plate (the pressing surface) on which is mounted a boiler formed of sheet metal which may be filled with water. An electric element, embedded in the sole plate, heats the water to the boiling point and also heats the sole plate to temperatures in excess of the boiling point. The iron is so constructed that it can be used for either conventional dry ironing or for steam ironing. In the top of the boiler is a large depressed hole, funnel-like in shape, by means of which water is put into the iron. Substantially the entire top of the boiler is covered with a hinged metal shield to the upper side of which the iron handle is attached. Depending from the under surface of said shield is a closure device, which fits into the funnel-shaped filler hole. The hinged shield is secured in position by a suitable latch located beneath the handle. To fill the iron, said latch is disengaged and the shield plate is swung upward and rearward — the depending closure device, attached to the shield, is thereby removed from the filler hole. The closure device is a silicone button attached to the shield plate in a floating manner and yieldingly pressed downward by an interposed coil spring. It serves the dual function of a means to seal the water in the boiler and a safety valve to permit the escape of steam in the event that excess pressure should be built up within the boiler.

In operation the steam accumulates in the steam dome in the upper part of the boiler and is forced from the steam dome downward through a small tube to a cavity between the floor -of the boiler and the sole plate. Orifices through the sole plate provide a means of escape for the steam and a means of dispersing it on the fabric being ironed.

The claimed innovation in the steam iron art is the combination of these elements: the hinged shield plate bearing the handle, the depending safety valve-closure, the large and easily accessible filler opening, and the special latch securing the shield in its closed position. Modifications and variations of these various elements -in combination form the basis of each one of the claims allegedly infringed (1, 2,t 3, 4, 6, 7, 8, 11, 12, 14 & 18) with the exception of Claim No. 18 which deals with the interrelation between the floor plate of the boiler and the sole plate. No one of the elements in the Schreyer patent, taken separately, appears to be new. The hinged handle long had been known to the iron art as evidenced by the Goodwin patent (issued in 1867, No. 75,150), Gray (1868, No. 79,067) and Waterman (1889, No. 406,608). The latch device used by Schreyer was similar to, but an improvement on, that used in Wonderlicli (1906, *163 No. 829,615). The combined filling-aperture closure and safety valve had been a feature of Theilgaard (1942, No. 2,279,215) and the Challenger and Press Master irons introduced as exhibits at the trial. If the Schreyer invention is patentable at all, it is because it combines the old elements, known to the art, in an ingenious fashion to achieve a new result.

The chief problem in the steam iron industry prior to the Schreyer innovation was that of rendering the opening and closure of the boiler filling-aperture speedy and convenient and of eliminating the need for handling hot parts. It had been found that the conventional screw-plug type closure of the prior art was highly unsatisfactory because the plug had a tendency to corrode at high temperature and stick in the aperture. It was often impossible to dislodge the plug even with resort to tools and frequently the end of the plug was broken off in attempts to loosen it. It was usual for the dissatisfied customer to return such irons to the local dealer; they could be repaired only by drilling out the plug stuck in the aperture and re-tapping it. The iron of the Theilgaard patent and the Challenger and Press Master models, referred to above, attempted to solve the screw-plug problem by resort to a closure positioned by spring pressure. The attempted solution proved unsatisfactory because the seal was not sufficiently tight to prevent leakage in all positions of the iron, and because the safety-valve-feature of the spring-type plugs permitted steam to blow off in the event of excess internal pressure in such a way that it would be likely to scald the hand of the operator. The Schreyer device appears effectively to have solved this “bugaboo” of the industry.

The presumption of validity of a patent acquires added strength, where, as in the case at bar, certain prior patents relied on by defendants to show anticipation of the discovery in question have been cited against the application in the course of proceedings in the Patent Office. Stevens v. Carl Schmid, Inc., 2 Cir., 1934, 73 F.2d 54. Not all of the patents on which defendants have relied were cited against the application in the Patent Office but among those which were cited are Goodwin, incorporating the idea of a hinged handle, and Theilgaard which has the combination closure and safety valve. These two are among the most pertinent prior discoveries, each of them proving the want of novelty in essential individual elements of the Schreyer combination. None of those patents cited for the first time by the defendants appears in any way to anticipate the new combination of Schreyer.

In assailing the validity of the claims in suit, defendants assert that they set forth mere aggregations of elements known to the prior art and that the resulting product is not of sufficient novelty to attain the status of patentability. The question raised by this line of defense is the familiar one of whether the device is a “combination” which has come to connote patentability, or an unpatentable “aggregation”. As recently noted by the Supreme Court, “The concept of invention is inherently elusive when applied to combination of old elements”, Great Atlantic & Pacific Tea Co. v. Supermarket Equipment Corp., 1950, 340 U.S. 147, 151, 71 S.Ct. 127, 129. The reduction of the criteria of patentability to verbal formulae does not eliminate the elusiveness of the concept; nor is it easy neatly to bracket the field of patentable discovery within pre-defined limits.
