Appeal No. 96-3612
Application 08/161,869
plastic winding drum 2 (column 7, lines 59 through 63) for the
purpose of dissipating the static electricity created by
friction between the magnetic tape 12 and the drum 2 (column
8, lines 3 through 11). No other portion of the winding drum
assembly is made from conductive plastics.
Appellants argue (Substitute Brief, pages 11 and 12)
that:
It is clear that none of Fujioka, Ogi or
Nakanishi even remotely suggest, either alone or in
combination, the provision of a magnetic head having
a die-molded head base formed from a conductive
resin material, and which has a housing envelope
defined by a conductive resin surface that contacts
the magnetic substance of a head chip in the manner
which secures the head chip to the base as claimed.
The Examiner has chosen simply to make unsupported
general arguments as to why it would be obvious to
use conductive resins in the field of magnetic
heads, but has not addressed any of the specific
claim limitations.
We agree. Even if we assume for the sake of argument
that it would have been obvious to one of ordinary skill in
the art to combine the teachings of Fujioka, Ogi and
Nakanishi, the combined teachings would still not have a head
base formed from a “conductive resin material” with a head
chip buried within a housing envelope portion of the head
base.
