Application No. 10/234,608
the known expedient of adding a perforation line to a tearing-capable structure to
be separated at the location of the perforation in the context of a carton material,
one of ordinary skill in the art would understand that this expedient is equally
applicable to separate Martin’s body (web) into individual cells, e.g., where the
cells are made of paper. Thus, it would have been obvious to one of ordinary
skill in the art to include at least one perforation in Martin’s body (web) because,
as Gray suggests, the perforation would have been expected to facilitate tearing
Martin’s body into multiple units or, in the language of the claims, to facilitate
tearing the web into individual panels, thereby providing an alternative means to
separate panels from the web.
Kim also teaches an insulated panel web with perforations. Specifically,
Kim discloses an automatic door panel producing apparatus which includes a
marking device 208 that “punches holes (not shown) on the inner plate material
202c” (column 4, lines 54-55), which inner plate material is combined with an
outer plate material and the void therebetween injected with insulated material to
form a door panel material (column 2, lines 27-59) and which perforated mark on
the inner plate material marks a cutting position (column 4, line 52) which is later
sensed causing a cutter to cut a door panel of a desired size from the door panel
material (column 6, lines 29-34). In disclosing an insulated door material
provided with punched holes to facilitate cutting the material into separate
panels, Kim is in effect disclosing an insulated web with at least one perforation
(punched hole) allowing for the web to be cut into separate panels. Thus, it
would have been obvious to one of ordinary skill in the art to provide Martin’s
