Application 08/501,542
supplying a short duration current pulse to a bucking coil”.
We agree with the Examiner. Determining the optimal
values of result effective variables would have been obvious
and ordinarily within the skill of the art. In re Boesch, 617
F.2d 272, 276, 205 USPQ 215, 219 (CCPA 1980). Since Sampietro
uses a short duration current pulse, and conservation of power
is a primary concern, experimentation with variable width
pulses would be expected to arrive at an optimal value. We
envision the optimal value to vary depending upon the
particular disk drive involved, disk drives being of different
sizes, and having actuator arms of differing inertial masses,
etc. Although Appellants dispute mere experimentation as the
vehicle for arriving at about 0.10 second, they have offered
no other explanation for its determination, nor have they
alleged unexpected results. Accordingly, we find the
limitation of about 0.10 second to be the obvious result of
experimentation to optimize a result effective variable.
Thus, we will sustain the Examiner’s rejection of claims 2 and
3.
With respect to claims 5, 10 and 14, Appellants
