Appeal No. 2001-0321
Application 08/888,671
the cable-to-connector interface [answer, pages 8
and 9].
The examiner’s position here rests on the proposition
that Nakajima’s cable-to-connector interface is susceptible to
EMI leakage, and thus in want of a ring-shaped ferrite core of
the sort disclosed by Fair-Rite, because it is not covered by
shielding frame 60. To the extent that Nakajima’s cable-to-
connector interface extends beyond the shielding frame 60,
however, it is encompassed by metallic shielding frame 64.
Since frames 60 and 64 are joined together to completely
surround the cable-to-connector interface, they ostensibly
would function to prevent EMI leakage at this point, thus
obviating any need for additional EMI shielding or attenuating
means. In this light, it is evident that the only suggestion
for combining Nakajima and Fair-Rite in the manner proposed by
the examiner stems from impermissible hindsight knowledge
derived from the appellants’ disclosure.
Accordingly, we shall not sustain the standing 35 U.S.C.
§ 103(a) of claims 64 and 68, and of claims 70 and 71 which
depend from claim 68, as being unpatentable over Nakajima in
view of the Fair-Rite reference.
