Appeal No. 2004-0127 Page 4 Application No. 09/765,605 The appellant’s invention is directed specifically to improvements in shoes having leather soles (specification, page 1) and, in this context, claim 1 requires “a tread made of leather.” Dassler discloses a sports shoe, such as a tennis shoe, having “a flexible plastics outsole” (Abstract; column 1, lines 44-49). There is no teaching in this reference, express or implied, that the sole can be made of leather. Thus, the primary reference clearly lacks disclosure or teaching of this feature and, since leather is not utilized, the problems arising in leather soles owing to exposure to water and vapor, to which the appellant has directed his inventive efforts, are not present in Dassler. The examiner then looks to Squadroni, concluding that Squadroni “teaches it is desirable to ventilate a shoe sole made of leather (see column 2, lines 65-68) to allow for the foot of the user to breathe,” and therefore “it would have been obvious to make the shoe sole of Dassler ‘685 out of leather, or any other known sole material, and ventilate it . . . to allow the foot of the user to breathe and prevent fluid build-up in the shoe of the user” (Answer, page 5). Squadroni discloses a shoe sole with a plurality of check valves for allowing air to be discharged from the inside of the shoe to ventilate the shoe.
