Opinion

ROCHE, Chief Judge.

The complaint herein charges defendant with infringement of four United ' States patents on hinges, consisting of one design patent and three mechanical patents.1

Defendant by its answer denied infringement and the validity of the patents in suit. In its amended answer the defendant alleged that patents 2,521,756, 2,535,324 and 2,586,573 are invalid for failure to comply with Sec. 112 of the Patent Act of 1952, 35 U.S.C.A. requir[332]*332ing an applicant for patent to clearly and specifically point out what is claimed to be new.

The plaintiff in this action, Butcher feoy Refrigeration Door Company is an Illinois corporation having its place of 'business in Harvárd, Illinois. Plaintiff is the owner of the four patents in- suit and manufactures and sells Butcher Boy hinges. The defendant, Phillips Refrigeration Products, Inc., is a California corporation having its place of business in San Francisco. Defendant is a distributor of the accused Birkenwald hinges which are manufactured by S. Birkenwald and Co., Inc., of Portland, Oregon. At the time that plaintiff began its hinge business there were many manufacturers of hinges in the United States, the most prominent being the Jamison Cold Storage Door Company of Hagerstown, Maryland. Various Jamison devices were introduced at the trial and the defendant relied upon them as prior art. Plaintiff is at present the second largest manufacturer of refrigerator doors and refrigerator door hardware in the United States, and its devices have met with considerable commercial success. Among those to whom plaintiff has sold hardware is S. Birkenwald and Co. of Portland, Oregon. This company purchased several hundred of plaintiff’s hinges and applied them to many doors which it manufactured and sold up and down the West Coast. S. Birkenwald Company ultimately-designed its own hinges, and at the time the designs, were made it had before it all of the prior art hinges as well as plaintiff’s hinges. Mr. Nau, president of Birkenwald pointed out slight differences in the hinges, but in effect admitted that the parts of -the hinges were identical and that their functions were identical.

The claims of each of the three mechanical patents in suit are for an' alleged combination. As to such claims, the. Supreme Court of the United States in that often cited case of the Great Atlantic & Pacific Tea Co. v. Supermarket Corp., 340 U.S. 147, 71 S.Ct. 127, 130, 95 L.Ed. 162, said:

“Courts should scrutinize combination patent claims with a care proportioned to the difficulty and improbability of finding invention in an assembly of ■ old elements. The function of a patent is to add to the sum of useful knowledge. Patents cannot be sustained when, on the contrary, their effect is to subtract from former resources freely available to skilled artisans. A patent for a combination which only unites old elements with no change in their respective functions, such as is presented here, obviously withdraws what already is known into the field of its monopoly and diminishes the resources available to skillful men. This patentee has added nothing to the total stock of knowledge, but has, merely, brought together segments of prior art and claims them in congregation as a monopoly.”

With this introductory statement of law, the court will discuss each of the mechanical patents under its own individual heading.

Patent No. 2,521,756.

Patent No. 2,521,756, hereinafter referred to as 756, was granted to Robert E. Slopa on an overlapping hinge on an application filed November 24, 1947. In general the hinge consists of a plate 21 which is secured to a door frame, and a second plate'29 which is secured to the door itself. A link 24 connects the two plates. A bolt 35 extends through the link 24 and the base plate 21 and means are provided for moving the end of the link toward and away from the plate 21 with the result that the pivot 27 about which the door swings may likewise be moved toward and away from the base plate 21. Moving the pivot point 27 permits one to compensate for wear of the gasket 17 between the door and the door frame. Defendant contends that long prior to any alleged date of conception of the hinge shown and described in patent 756, a hinge embodying without exception all of the elements of this hinge was manufactured by Jamison Cold Storage Door Company of Hagerstown, Maryland, [333]*333hereinafter referred to as the Jamison hinge.2

This Jamison hinge, like the hinge of patent 756 includes two mounting plates which are of the same identical structure as the mounting plates 21 and 29 of patent 756 in suit. The Jamison hinge (Def. Ex. A) includes a link 25 pivotally mounted at its outer end to one of the mounting plates and terminating in an inner end portion providing an arm 28a disposed substantially parallel to such mounting plate. Said link 25 in the Jami-son hinge, like the link of patent 756, is pivotally connected inwardly of its inner end portion to the other mounting plate so that such other mounting plate, when attached to a door, will have a swinging movement to open and closed position about its pivotal connection 27 with the link. In the Jamison hinge is a bolt 31 identical to bolt 34 of the hinge of patent 756. Such bolt 31 is carried by one of the mounting plates at right angles thereto and extends outwardly through the opening 33 in the arm of the link. On the bolt of the Jamison hinge, like the bolt of patent 756, is a spring 34 between the arm and the mounting plate to which the bolt is attached. Threaded on the outer end of the bolt of the Jamison hinge, like the bolt of patent 756 is a nut 36-37 for applying pressure to the arm 28a to tilt the link 25 about its pivotal connection with the mounting plate to which it is attached and to hold the link 25 at an adjusted angle relative to such mounting plate.

The record reveals that Robert E. Slopa, in order to assemble 756, reversed the mounting of the Jamison hinge, as shown in patent, 1,987,512, i. e., he mounted the plate which carries the link, on the door frame instead of on the door, the proper mounting position for the Jamison hinge; and in order to increase the mechanical efficiency of this “reversed” Jamison hinge, diagonally positioned the link 24 (25 in Jamison) at about a 45 degree angle rather than allowing it to remain at ninety degrees.

In the court’s view the reversal of the mounting position of Jamison does not constitute invention and involves only a matter of choice. The claims of 756 are drawn to a hinge and must be limited to the elements of a hinge. These elements are not changed to any great degree, either in structure or function from Jamison and in so far as structure is concerned the claims of 756 read directly on Jamison.

As to the angling of the. link, this in the court’s view required nothing more than the knowledge of a mechanic skilled in the trade, for all that was hoped to be accomplished by this minor change in Jamison was a more mechanically efficient arrangement of elements which were already well known to the hinge industry.

In substantiation of the fact that there is not one element which is found in 756 which is not found in Jamison, George W. Slopa, brother of the patentee of patent 756, stated the following under cross-examination :

“Q. In other words, am I correct in this statement.
