Appeal No. 1997-0846
Application No. 08/474,950
Admitted Prior Art. Essentially, for the reasons set forth in
appellant's brief, we do not find the stated rejection to be
well taken. As emphasized by appellant, the appealed claims
are directed to a removable, non-brittle, water soluble
thermoplastic spacer for use to space an electrical component
from a printed circuit wiring board to which the electrical
component will be attached. Baechtold does not relate to the
technology of concern to appellant. What Baechtold's
described invention relates to is a water-soluble, heat-
sealable film material suitable for use
1) as a water soluble wrap or 2) for fabrication into water-
soluble envelopes. Baechtold's film material and water
soluble wrap is used for the packaging of household materials
intended to be dissolved or dispersed in water, for example,
soap powder or detergent powder. That appellant acknowledges
(specification page 2) that wash away lactose spacers have
been used to space an electrical component from a printed
wiring board in the prior art does not aid the examiner's
rejection, since there is no indication in Baechtold that the
prior art water-soluble film and wrap material would overcome
the problems relating to the use of the prior art lactose
