Appeal No. 97-2820
Application No. 08/432,443
Naiki discloses two electrodes G3 and G4 (Figure 7) that are
each formed from a first part 40 with a single aperture 50
therein, and a second part 60 positioned within the first part
40. The second part 60 includes three inline apertures 70B, 70G,
and 70R. A continuous flange 64 (Figure 6) on the second part 60
is connected to a continuous flange 44 (Figure 5) on the first
part 40. Thus, the two parts 40 and 60 are connected to each
other along one continuous ledge (Figure 7). 2
According to the examiner (Answer, page 5), Hernqvist
discloses “a cup shaped part 22 with ledges (see FIG. 5, support
portions 80) and an aperture plate with offsets (eyelets 96) for
attaching an auxiliary electrode member (see col. 4, line 11-12,
shield member 86) to the main electrode 22.” The examiner is of
the belief that “[i]t would have been obvious to use a cup shaped
part with ledges for attaching an auxiliary electrode member with
offsets, as disclosed by Hernqvist et al., instead of the side
wall member, as disclosed by Naiki, as a design expedient”
(Answer, page 5).
2The examiner has not addressed the issue of whether it
would have been obvious to one of ordinary skill in the art to
use a continuous ledge connection in lieu of the claimed
connection at the four spaced ledges and four corners.
