Appeal No. 1998-0463
Application No. 08/450,849
We affirm the rejection of claim 20. It follows that the
rejection of dependent claim 21, which stands or falls with
claim 20, is likewise affirmed.
The device of claim 20 requires, inter alia, a display
including a plurality of LEDs arranged in columns, with each
LED in each column indicating the degree of severity of the
harmonic of interest.
In our opinion, the combined teachings of the Lowenstein
documents would have been suggestive of the aforementioned LED
feature of claim 20 since Lowenstein '114, in particular,
addresses the alternative of a plurality of LEDs corresponding
to the number of steps in a display scale (multi-step light
bar) 14, and expressly indicates that the display scale can
include “multiple light bars corresponding to the number of
harmonics measured.” For the above reason, we determine that
claim 20 is unpatentable under 35 U.S.C. § 103.
