Appeal No. 1999-2277
Application 08/803,578
The signal terminals[] of the slider[] are directly
connected to the signal electrodes[] on the wiring
substrate[] by . . . using gold balls. . . . The grounding
terminal[] of the slider[] is also directly connected to
the grounding electrode[] on the wiring substrate[] by . .
. ball bonding using a gold ball. Column 6, line 65, to
column 7, lines 4.
We find no evidence in Kudo that teaches or suggests that
the gold ball bonding is used to attach or support an attachment
of the magnetic slider to the flexible wiring substrate. We
find that the gold ball bonding is only used to attach the
signal electrodes to the respective signal terminals of the
slider.
We are not inclined to dispense with proof by evidence when
the proposition at issue is not supported by a teaching in the
prior art reference or shown to be common knowledge of
unquestionable demonstration. Our reviewing court requires this
evidence in order to establish a prima facie case. Piasecki,

Based on the evidence and arguments presented, and the
pertinent law in this matter, we find that the Examiner has
