Appeal No. 96-4157
Application 08/142,772
which act against filter cartridge flange(s). As indicated
above, Berglund's locking bars 9 act against filter cassette
flanges via broad side surfaces on the bars. The examiner's
insistence that each of these broad side surfaces constitutes
a "free edge" as recited in the appellant's claims (see page 7
in the answer) runs counter to any reasonable interpretation
of this term.
Thus, the examiner's prior art evidence fails to
establish a prima facie case of obviousness with respect to
the subject matter recited in claims 4 and 18, and in claims 6
and 10 through
17 which depend from claim 4. Accordingly, we shall not2
sustain the standing 35 U.S.C. § 103 rejection of these
claims.
2This being so, we find it unnecessary to delve into the
merits of the appellant's evidence of non-obviousness.
