Appeal No. 1997-3098
Application 08/377,776
the integral of its input with respect to time.” The 2
discussion of the integrator circuit or means for integrating
in appellant’s specification (page 9, lines 13-23) is
consistent with this definition. The examiner has not
explained, and it is not apparent, why a component which
algebraically sums currents is an integrator circuit or means
for integrating as those terms are used by appellant or would
have fairly suggested such a device to one of ordinary skill
in the art. Consequently, the examiner has not carried the
burden of establishing a prima facie case of obviousness of
the invention recited in claims 5-7 and 12-14. We therefore
reverse the rejection of these claims.
DECISION
The rejection of claims 1-14 under 35 U.S.C. § 103 over
Birdsong in view of Tucci ‘598 and Tucci ‘557 is reversed.
REVERSED
