Appeal No. 94-4034
Application No. 07/804,160
5. A polymer mixture comprising:
(A) 20-60 parts by weight of polyphenylene ether resin;
(B) 40-70 parts by weight of polystyrene resin, high-impact
polystyrene resin, or a mixture thereof;
(C) 5-20 parts by weight of an impact strength agent; and
(D) 2-10 parts by weight of talcum,
wherein component (C) comprises a mixture of 2 linear
block copolymers.
The references of record relied upon by the examiner are:
Kosaka et al. (Kosaka) 4,483,958 Nov. 20, 1984
Abe et al. (Abe) 5,086,105 Feb. 04, 1992
(Filed Dec. 11, 1989)
Claims 5 through 14 stand rejected under 35 U.S.C. § 103 as
unpatentable over the combined disclosures of Kosaka and Abe.2
We have carefully reviewed the entire record before us,
including each of the arguments and comments advanced by the
examiner and appellants in support of their positions. This
review leads us to conclude that the examiner’s § 103 rejection
is well-founded. Accordingly, we will sustain the examiner’s §
103 rejection. Our reasons for this determination follow.
As a preliminary matter, we note the examiner’s statement
(Answer, page 2) that the appealed claims stand or fall together
because appellants do not state that the appealed claims do not
stand or fall together. Nowhere do appellants dispute this
2At page 2 of the Answer, the examiner has withdrawn
the remaining rejections made in the final Office action
dated February 2, 1993.
