The examiner responds that the insulating resinous filler
29 of Oosuka and the shielding portion 510a meet the recitations
of claims 9 and 10 [answer, page 9].
We will not sustain the examiner’s rejection of
independent claims 9 and 10 because the examiner has failed to
establish a prima facie case of obviousness. Filler 29 of Oosuka
is an insulating oil. This is not a resinous filler (claim 9)
and there is no disclosure within Oosuka of the dielectric
constant of this oil or of the dielectric constant of the primary
spool 514 (claims 9 and 10). Although they are different
materials, the dielectric constants are not discussed. Claim 9
also recite a shielding portion projecting axially from an end of
the secondary spool to cover the high tension terminal immersed
in the insulating resinous filler. Claim 10 recites a shielding
portion projecting longitudinally from a straight line between
the end of the outer periphery of the high tension terminal
immersed in the insulating filler. Both claims also recite that
the primary coil is not wound on the shielding portion of the
primary spool. The examiner has not specifically addressed these
limitations of the claims. The shielding portion 510a of Oosuka
identified by the examiner refers to a bottom portion of the
secondary spool. This does not meet the recitation that the
