across the front and hack of the chair seat, to the upper concave surfaces of which rungs the arcuate slats are secured; (3) A produced result of a curvature of the chair seat in both directions, throughout the breadth and depth of the chair seat, so that this seat at the centre is substantially spherical in form.
Counsel for patentee freely admit that element (1) (reversely curved, arcuate slats running from the front to the back of the chair seat) is very old in the prior art. These same counsel also admit the clear antiquity of element (3) (the result produced, the double curvature of the chair seat); so that their claim of patentability is reduced to the second element. Admitted, too, is the fact that the patent is in no sense revolutionary and that “the prior art in the field of chairs is crowded.” Just how crowded is this field is evident from a mere enumeration of prior patents in the field, disclosing elements strikingly similar to those of the patent in suit.
Thus the Buckel patent (1868), No. 85,-363, has “front and rear cross bars,” in the nature of arcuate' rungs. In the Jones patent (1931), Des. No. 85,182, transverse arcuate rungs provide widthwise curvature in a wicker chair seat. ’ And very close to the- Murdock patent is the Debski patent (1929), Des. No. 79,283; for Debski has both the double curvature and the two transverse arcuate rungs. Indeed, the only differences here are that Debski’s rungs are made of a different material from those of Murdock, and the two Debski rungs are placed one in front of, and one just ■back of, the centre of the chair seat, while Murdock has positioned his rungs one at the front, and one at the rear, of the chair seat. In both Debski and Murdock, the slats (running from front to rear) rest upon the concave surface of the transverse, arcuate rungs. Compare, too, the McKee patent (1932), No. 2,011,067 with “slats p-f wood so placed as to give resiliency and so formed as to comfortably fit the form of a person using the chair,” and the suggestion “a cushion shaping itself to the flexible ‘saddle curves’ in the seat -might be used;” the Bergstrom patent (1927), Des. No. 76,980; the Bruening patent (1935), No. 2,028,823; the Lucas patent (1934), Des. No. 94,089, and particularly the Trudo patent (1931), No. 1,827,-124. Models of ancient stools and more modern Chippendale chairs are strikingly similar to Murdock.
In the light, then, of the prior art, Murdock has produced an old result (double curvature of the chair seat) through old means (curved slats positioned on the concave surface of transverse arcuate rungs). Surely, under these circumstances, there is nothing patentable in Murdock’s merely altering the position of the arcuate rungs. At best, Murdock discloses only a non-patentable aggregation with only slight and non-essential variants from chair seats long known in the art. His chair seat may be (as his counsel assert) cheaper, better looking and more comfortable than those of his predecessors in.this field; but much more than these attributes is needed to satisfy the concept of patentability.
Said Circuit Judge Parker, speaking (with an elaborate citation of authorities) for our Court in Young v. John McShain, Inc., 4 Cir., 130 F.2d 31, 32: “We agree with the court below t-hat none of the claims is valid but that all cover mere aggregations of devices, -which were old in the art of steel-concrete construction, and which perform in the aggregation merely the functions which they performed in the prior art, without any new effect or resultant from their -having been brought together. It is well settled that invention cannot be predicated of such aggregation of old elements even though their bringing together may have resulted in a useful product.”
Of like effect is the statement of our Circuit Judge Soper, in Bulldog Electric Products Co. v. General Electric Co., 4 Cir., 105 F.2d 466, 468: “It remains to consider whether the particular structure which Kempton devised amounted to invention. It is apparent that it comprised little that was not familiar to the art, and that its claim to ingenuity depends upon the peculiar form of the anchor plate described in claim 3 as a metal plate ‘secured to the rear of said base and having a portion extending forwardly at right angles to the
