Appeal No. 98-0984
Application 08/428,561
"control electronics," and therefore would not be included in
the electronics 44, 46 of Voss, which are defined as "six
MOSFET or IGBT-type semiconductors 46" (col. 4, lines 37 and
38) and "a motor phase sequencing circuit board 44" (col. 4,
line 61).
However, even assuming that Voss would suggest to
one of ordinary skill that the rectifier and capacitor be
placed inside the housing 48, we do not consider that the
apparatus of claim 1, which calls for the capacitive component
to be outside the housing, would have been unobvious over the
combination of Voss and Ruff. As indicated above, Ruff
discloses that the rectifier and capacitor, along with the
SCRs 9 to 14, sequencer 18 and control center 19, may be
placed outside the housing. Given this disclosure, it would
have been obvious to one of ordinary skill that each of these
various components might be placed either inside or outside
the housing. The decision as to whether to locate a
particular component inside or outside the housing would be an
obvious matter of design choice in the sense that the decision
would be essentially an economic one, weighing
