Rejections over Sakazume
Sakazume discloses a thermoplastic resin composition
which contains 1-99 wt% of a polyamide resin, 1-99 wt% of
another resin selected from a specified group, and 0.1-100
parts by weight, based on 100 parts by weight of the above
resins, of a multi-phase structure thermoplastic resin
composed of 5-95 wt% of an acid group-containing olefin
polymer or copolymer and 5-95 wt% of a vinyl polymer or
copolymer obtained from at least one kind of vinyl monomer,
either one or both components of the multi-phase structure
being in the state of a dispersed phase having a particle
diameter of 0.001 to 10 Fm (col. 3, lines 25-44; col. 10,
lines 22-27).
The examiner argues that the disclosure by Sakazume that
the olefin polymer or copolymer and the vinyl polymer or
copolymer have a multi-phase structure is sufficient evidence
that the vinyl polymer or copolymer remains partially
encapsulated by the ethylene polymer or copolymer during the
manufacture of the composition to shift the burden to the
appellants to prove otherwise (answer, pages 5-6). The
