layer would also be capable of functioning as a parting agent
during a heat compaction treatment.
Furthermore, while the coating taught by Foster serves as
a parting agent, Foster teaches away from using the coating as
a permanent barrier layer by suggesting its removal after use
as a parting agent (see Foster at col. 4, l. 56-57 and claim
1).
Additionally, we find no factual basis to support the
examiner’s conclusion that the Foster coating would be
expected to function as a barrier to sodium ion migration.
The examiner has given no reason, nor are we aware of any, as
to why the coating of Foster, which is particulate in nature,
could be expected to function as such. This deficiency in the
examiner’s reasoning is not cured by resort to the Nordberg
reference since the coating or film of Nordberg, like that of
Foster, is used solely as a parting agent and is colloidal in
nature, produced from a metallic oxide powder dispersed in
water.
For the foregoing reasons, the decision of the examiner
is reversed.
