Appeal No. 1998-0522
Application No. 08/327,882
and appellants, we agree with appellants that the examiner has not
established a prima facie case of obviousness regarding the claimed
subject matter within the meaning of 35 U.S.C. § 103. Accordingly,
we reverse each of the foregoing § 103 rejections.
Even were we to agree with the examiner that Masamoto or Kadoi
teaches a polyphenylene sulphide composition comprising at least
one compound generically inclusive of claimed compounds (C1) and
(C2), we find that the examiner has not demonstrated that Masamoto
or Kadoi would have suggested cross-linked compounds as required by
the claims on appeal. Nor has the examiner demonstrated that the
product resulting from cross-linking compounds (C1) and (C2) would
reasonably have been expected to behave in the same or similar
manner as the compounds listed in the Masamoto or Kadoi references
or the blend (non-cross-linked) compounds thereof. We simply find
that the examiner has not adequately explained why one of ordinary
skill in the art would have been led to a polyphenylene sulphide
composition consisting essentially of a polyphenylene sulphide and
a cross-linked composition consisting of compounds (C1) and (C2)
which have been cross-linked.
In view of the foregoing, we reverse the decision of the
examiner rejecting all of the appealed claims under 35 U.S.C.
§ 103.
