Appeal No. 1999-0960
Application No. 08/785,437
"the fold backs of [the] accordion fold pack" must be
interpreted as meaning all the fold backs of the fold pack.
The examiner further finds claim 1 (and claim 13) to be
unpatentable over Wright under § 103(a) because (answer, pages
3 and 4):
it would have been obvious to someone of
ordinary skill in the art at the time of the
invention to align the edges of the protective
mask [of Wright] with the fold backs of the
filter so that the protective mask is adhesively
attached along the entire edge of the plurality
of fold backs and so that [the] seal between the
filter and the protective mask is amplified in
strength. Furthermore, the function of the
protective mask adhesively
attached to
the filter is
the same as
the
applicants, to
extend the
useful life of
the pleated
filter (column
1 lines 37-
38).
Therefore,
attaching the
protective
mask along an
entire length
of the fold
backs would
have been
obvious for
further
