show the cell structure of the appellants' dielectric.
Specifically, "[t]he cited references fairly show the claimed
density and thickness but not the cell structure." (Id.)
Because the compressive stiffness of a dielectric
material depends on its cell structure inter alia, and neither
Fox nor Wilkenloh show the cell structure of the appellants'
dielectric, we are unpersuaded the claimed compressive
stiffness necessarily flows from the teachings of the applied
prior art. Accordingly, we are further unpersuaded that
teachings from the prior art would have suggested the
limitations that "said dielectric material has ... a
corresponding predetermined compressive stiffness of at least
1000 pounds per linear inch ...." The examiner fails to
establish a prima facie case of obviousness. Therefore, we
reverse the rejection of claims 9-11, 13-20, and 22-25 as
obvious over Fox in view of Wilkenloh.
