Appeal No. 95-4047
Application 07/931,206
term “transparent grades of polyolefins” means that the
polyolefins are transparent. The examiner provides no
explanation as to why the term “film grade” is indefinite, and
none is apparent.
However, “acrylics such a film grade
polymethylmethacrylate” in claim 4 is indefinite because it is
not clear whether this term encompasses acrylics generally or
only those which have some unspecified similarity to
polymethylmethacrylate. Also, “related copolymers” in the
expression “acrylics such a film grade polymethylmethacrylate
and related copolymers” is indefinite because it is not clear,
in view of appellants’ disclosure, how the copolymers are
related, e.g., with respect to composition, physical
properties, etc. For these reasons, we sustain the rejection
under 35 U.S.C. § 112, second paragraph, of claim 4 and claim
5 which depends therefrom.
DECISION
The rejections of claims 1-5 under 35 U.S.C. § 103 as
being unpatentable over Vargas or Miles, each taken with
Schramer, and under 35 U.S.C. § 112, first paragraph, are
