v. Int'l Trade Comm'n, 126 F.3d 1473, 1477, 44 USPQ2d 1358,

On page 9 of the brief, appellants argue that “the
Farwell patent does not relate at all to modifying the set
point of the output voltage signal, as claimed . . . .” The
examiner’s response, answer at page 6 is that “figure 1 of the
Farwell patent, a [sic, is] the transient voltage, clearly
labeled as the input to the two differential amplifiers with
the voltage set points - ŠV and + ŠV, connected to the two
different differential amplifiers 31 and 32, respectively.”
We have studied the Farwell patent and reviewed the
examiner’s comments regarding Figure 1. We, like appellants,
find no disclosure in Farwell where the set point of the
output voltage is being adjusted in response to the transients
caused by a load on the converter. The set points, - ŠV and +
ŠV, which the examiner calls the claimed “set point” are
independent of the output voltage of the converter. They
