instability). Gareis solves the problem of the prior art by
having the longitudinal side folded as recited in claims 2 and 3.
Accordingly, Gareis improves upon the design of Dembiak in terms
of slippage. Therefore, it would have been obvious to combine
Gareis with Deitz and Dembiak, and we will sustain the
obviousness rejections of claims 2 and 3.
Regarding claims 4 through 6 and 8 through 10, the examiner
combines Krabec with Deitz and Dembiak. Appellant argues (Brief,
pages 9-10) that since Krabec relates to an overall shield,
rather than to individual shields of twisted pairs, the skilled
artisan at best would modify Deitz's overall shield with Krabec's
teachings rather than the individual shields.
Krabec (column 1, lines 32-46) teaches that thin metal foils
are generally made as a laminate with a polyester or
polypropylene member to prevent structural failure. Further, the
polyester or polypropylene member causes a nonconductive gap or
slot through the shield which allows transmission of RF energy
therethrough. Krabec teaches using metal layers on both sides of
the polyester or polypropylene member to reduce the leakage.
Although Krabec's disclosure relates to the overall shield, the

overlapping edge of Deitz's individual shields. Accordingly, the
