Application 09/818,023
reinforced region, the first section of the fold line being wider than the
second section of the fold line, and a transition zone formed between the
first and second sections of the fold line (Finding of Fact 1). As admitted by
Appellant, however, it was known by those of skill in the art at the time of
Appellant’s invention that fold lines in thinner material must be narrower
than fold lines in thicker material (Specification 36:24-26). Thus, a person
of ordinary skill in the art at the time of Appellant’s invention would have
appreciated that the score lines extending across the lines of reinforcement
of Campbell’s carton blank should be formed so as to be wider in the
reinforced area (the thicker material) and narrower in the areas that are not
reinforced (the thinner material). Moreover, Seufert ‘916 evidences that
techniques were well known in the art at the time of Appellant’s invention
for forming fold lines or scores in plastic carton blank material that are wider
in a first section and narrower in a second section, with a transition zone
between the first and second sections that gradually widens from the
narrower width to the wider width (Findings of Fact 5-6). Thus, one of
ordinary skill in the art would have been able to implement one of the well
known and predictable techniques mentioned by Seufert ‘916 to score a fold
line in the reinforced carton blank material of Campbell having a first
section in the reinforced region that is wider than a second section in the
region that is not reinforced, with a transition zone between the first and
second sections that gradually widens from the narrower width to the wider
width, and would have been prompted to do so while the bond between the
tapes and the paper is not dry to ensure firm bonding of the tape on both
sides to the paper (Finding of Fact 2), in order to form the score lines so as
to be wider in the reinforced area (the thicker material) and narrower in the
