Appeal No. 95-0244
Application 08/035,832
The subject matter of the appealed claims relates to a
composition consisting of a polymeric acetal and zinc oxide
which is suitable for use in the preparation of a plumbing
fixture and to the method for producing a shaped article
suitable for use as a plumbing fixture. Claims 1 and 10 are
illustrative of the appealed claims and read as follows:
1. A composition suitable for use in the preparation
of a plumbing fixture, consisting of a polymeric acetal and
zinc oxide in an amount from about 1 to about 20% by weight,
wherein the fixture exhibits resistance to the build-up and
adhesion of mineral deposits.
10. A method for producing a shaped article suitable
for use as a plumbing fixture which exhibits resistance to
the build-up and adhesion of mineral deposition, consisting
essentially of the steps of: (a) making a blend consisting
of polymeric acetal and from about 1 to about 20% by weight
of zinc oxide; and (b) shaping said blend to form a shaped
article.
Appellant made no statement that the claims do not stand
or fall together. 37 CFR § 1.192(c)(7). Accordingly, we will
limit our consideration to claim 1 in considering the
examiner's rejection of the appealed claims.
The reference relied on by the examiner is:
