Appeal No. 2006-2007
Application No. 09/996,225
The focus of Appellants’ arguments is that the arrangement
of transistor 59, resistor 591 and capacitor 592 of Hwang does
not reasonably correspond to the claimed low pass filter (brief,
page 3). Appellants further point out that the arrangement of
these components do not remove high frequency components and
therefore, is not a low pass filter (brief, page 4). The
Examiner responds by stating that Hwang provides for components
similar to a series combination of a resistor (106) and a
capacitor (130) providing an output at node B shown in
Appellants’ Figure 1 (answer, page 10). Appellants argue that
the components identified by the Examiner as making up the low
pass filter actually pass the extremely high frequencies and fail
to constitute a low pass filter (brief, page 4; reply brief,
pages 2-3).
After a review of Hwang, we agree with Appellants that the
arrangement of transistor 59, resistor 591 and capacitor 592,
shown in Figure 1 of the reference, is not a low pass filter.
Such arrangement, as positioned between nodes A and C, is not the
same as what is shown between nodes A and C of Appellants’ Figure
4
