and apart from the metal cylinder covering the connecting
part. The Nakajima system has no such means. 4
Fair-Rite discloses a cable and connector EMI suppressor
kit having ring-shaped ferrite cores among its components.
In proposing to combine Nakajima and Fair-Rite to reject
the appealed claims, the examiner concludes
that at the time the invention was made it would
have been obvious to one of ordinary skill in the
art to have provided a ring-shaped ferrite core, as
taught by Fair-Rite, along the cable of Nakajima to
reduce or prevent reception or leakage of EMI. In
addition, since Fair-Rite does not specify a
preferred location along the cable, the skilled
artisan, faced with the decision of where along the
cable to place the ferrite core, would naturally
drawn [sic] upon his/her own ordinary skill and
knowledge readily available at the time, to place
the ferrite core in the most beneficial location
along the cable.
Nakajima recognizes the existence of EMI in the
connector-to-connector interface . . . and provides
a metallic shielding frame (60) to help reduce
interference at the point of connection. However,
no EMI protection is provided along the cable at the
cable-to-connector interface. As would be
recognized by the skilled artisan, the cable-to-
connector interface of Nakajima . . . is a point
that is highly susceptible to EMI leakage and is not
covered by the metallic shielding frame (60). Thus,
use of a ring-shaped ferrite core along the cable
would most obviously and advantageously be placed at
4Counsel acknowledged at the oral hearing that the
assertion on page 5 in the main brief that the Nakajima system
includes a ferrite ring is mistaken.
