F. C. Russell Co. v. Comfort Equipment Corp., 194 F.2d 592, 93 U.S.P.Q. (BNA) 119, 1952 U.S. App. LEXIS 4322 (7th Cir. 1952).

Opinion

FINNEGAN, Circuit Judge.

The plaintiff below, the F. C. Russell Company, appeals from a judgment order of the United States District Court for the Northern District of Illinois, Eastern Division, which dismissed its complaint charging Comfort Equipment Corporation with infringement of Ensminger patent No. 2,262,670, and seeking injunctive and accounting relief.

In its answer Comfort Equipment Corporation denies infringement. It also urges invalidity for lack of invention over the prior art, and charges misuse by plaintiff-appellant of the patent in suit.

The District Court held the patent invalid as it represents a mere congregation of elements which perform no new function or result in assembly; that, if valid, claims 3 and 10 of the patent would be infringed by defendant’s structure; and that Russell must be denied all relief because it has misused its patent. The opinion of the District Court, 97 F.Supp. 784, 785, reviews the pertinent facts and principles of the law that impelled that court to dismiss the case.

The patent involved is for a combination storm and screen window. One of the objects of the patentee was to provide a combination which might be permanently installed and so constructed as to readily permit the removal, from within the building, of glass panels used in the wintejr season and the insertion in lieu thereof of screen panels for summer use. A further object was to provide an arrangement which would permit installation of a single stand *593 ard size factory-made rigid frame that could 'be made to fit a range of sizes of window openings, such as distorted or out-of-square openings, and which, after installation, would be self-adjustable to the distortion, expansion, or contraction of the window aperture.

The structure of the patent in suit is an arrangement or combination of three elements: 1st — a rigid panel receiving frame for receiving glass and screen panels; 2nd —channel shaped sealing members which embrace the sides of the rigid panel frame; and 3rd — means for holding the sealing members in place against the walls of the window aperture, and for applying a clamping pressure to the flanges of the sealing member in order to hold the panel receiving frame in fixed position with respect to the sealing members.

The trial court found that the different elements of the plaintiff-appellant structure function in relation to each other in the following manner:

“The panel receiving frame is embraced by the resilient flanges of the sealing channels, with the inturned edges of the sealing channels, both during and after installation, slidably and frictionally engaging the opposite, flat, inner and outer faces of the panel receiving frame with a yielding pressure.
“The screw secures the sealing channel (s) in place against the sides of the window casing and the blind stop in tight sealing relation with both, and also has clamping effect on the sealing channel to increase the grip of its flanges on the frame.
“The frame is thus mounted in the window aperture by frictional clamping engagement with the flanges of the sealing channel which sealing channel in turn is permanently, positively and securely mounted in the window aperture by the screws. The panel receiving frame has connection with the window aperture only by way of the red sealing channel and thus ‘floats’ within the channel.
“Each of the elements cooperates with each of the other elements in producing this functional relationship between them.”

Claims 3 and 10 of the patent are alleged to be infringed — they are as follows:

Claim 3. “A storm sash for mounting in a window aperture of a building comprising, a panel receiving frame having rigidly connected side and transverse hollow metal bars provided with flat inner and outer side faces-, side and transverse sealing members mounted on side and transverse bars of said frame, each sealing member being formed of sheet metal and of channel shape, having a base portion adapted to engage a wall of a building aperture and resilient flanges having inturned edge portions slidably engaging the inner and outer flat faces of the frame bars, each sealing member extending the full length of frame bar upon which it is mounted, one sealing member slidably receiving the end of another at corners of the frame, whereby the sealing members are independently adjustable sidewise and angularly in the plane of the panel receiving frame to seat upon the walls of a building aperture, and means for holding said sealing members in place against the walls of the window aperture and for applying a clamping pressure to the flanges of the sealing members to hold the panel receiving frame in fixed position with respect to the sealing members.”

Claim 10. “A structure of the character described for mounting across a building aperture comprising a panel receiving frame including rigidly connected side and transverse frame members, channel shaped sealing members embracing portions of the frame members and having spaced flanges slidable over opposite faces of the frame members for tilting and bodily movement of the sealing members relative to the frame members in adjusting the structure to apertures of different sizes and shapes, and means extending' through the flanges of the sealing members for securing the structure in place and for drawing the flanges together to clamp the frame members therebetween.”

Speaking through Mr. Justice Jackson, the Supreme Court, in Great Atlantic & Pacific Tea Co. v. Supermarket Corp., 340 U.S. 147, said on pages 152-153, 71 S.Ct. 127, at page 130, 95 L.Ed. 162: “Courts *594 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.”

The trial court in the case at bar has carefully scrutinized the claims of the patent in suit in order to determine whether or not the aggregation or conjunction of the old elements produces a new or different function than that theretofore produced by them.

As to the first element, that is to say, a rigid panel frame designed to receive interchangeable glass or screen panels, the court found:

“Combination storm windows consisting of a rigid frame with interchangeable glass and screen panels which can be removed from inside a room are prior art to the patent in suit. They were found in both wooden windows and in metal combination storm windows having interchangeable glass and screen panels before Ensminger filed the application for the patent in suit.
