Appeal No. 2003-0589
Application No. 09/564,326
Even when all of the above reference are combined, they
fail to teach or suggest a method for efficiently
producing trapezoidal bags without waste material in
which the bags have top and bottom edges, each with a
functioning zipper where the bottom edges of each
plastic bag are sealed along a sealing line disposed
parallel to and proximate to the zipper on the bottom
edges of each plastic bag.
In considering the prior art references to Ouchi and Clark,
we note, as appellant has, that neither of these patents is
directed to a method or process of making non-rectangular zipper
closable plastic bags. Moreover, while the examiner has found
that Clark discloses or teaches "a plastic sheet (48) having a
plastic zipper strip (102) on both the first and second edge
(Fig. 3) to provide a reclosable plastic bag for sealably
packaging a wide variety of articles including food products"
(final rejection, page 2), we find no such teaching in the Clark
patent.
Instead, it is readily apparent from even a cursory review
of the Clark patent that Figure 3 therein is directed to a
laminate composite for use in making reclosable plastic bags,
wherein the laminate composite includes first (48) and second
(68) sheets of plastic film material bonded together to form a
first composite (77), a pair of soft malleable wire strips (84a)
