Appeal No. 2001-0225
Application 09/085,021
form 10 shown in Baker’s Figure 2. As described in the
reference,
[f]orm 10 includes an upper panel 12 having an upper
(or trailing) flap 14 and a pair of side flaps 16.
Panel 12 may also be provided with a window 18 so
that the mail piece formed when form 10 is folded
and sealed may be delivered to an address printed on
a sheet in the mail piece. An adhesive A is applied
to flaps 14 and 16 to provide for sealing of form 10
to form an envelope. Preferably adhesive A is
applied to flaps 14 and [16] as spaced stripes or
spots so that form 10 may be driven through the
apparatus of FIG. 1 by segmented rollers contacting
form 10 in the spaces between the stripes or spots
of adhesive A to prevent contamination of the
rollers when adhesive A is moistened prior to
sealing and, also, to reduce curling of the form.
Adhesive A is preferably a remoistenable adhesive
which is moistened for sealing . . ., but the use of
self-adhesive or other suitable methods of sealing
is within the contemplation of the subject
invention. Flaps 14 and 16 are attached to upper
portion 12, as is a rectangular lower portion 20,
along preformed fold lines 24, which are preferably
pre-creased to facilitate uniform folding [column 5,
lines 39 through 60].
Likening Baker’s form 10 to the intermediates involved in
the method recited in claim 18, the examiner concedes (see
page 4 in the answer) that the form 10 does not meet the claim
limitation requiring the intermediates to comprise “first and
second lines of weakness formed in the sheet adjacent, but
spaced from and substantially parallel to, the first and
