Appeal 2007-0008
Application 09/818,023
Amendment filed November 16, 2006, subsequent to the filing of the Appeal
Brief, Appellant cancelled claims 33-37. The Examiner entered this
Amendment on November 30, 2006. Consequently, this appeal involves
only claims 1-15. We have jurisdiction over this appeal under 35 U.S.C. § 6
(2002).
Appellant’s claimed invention is directed to a method of making
reinforced paperboard cartons. In particular, Appellant forms multi-width
fold lines where a fold line transitions across the edge of a reinforcing ribbon
(Specification 10). In cases where fold lines extend transversely across
reinforcing ribbons, and thus transition from the thinner or lower caliper
base sheet to the thicker or higher caliper reinforced regions, the fold lines
are formed in such a way that they do not cause cracking or otherwise
interfere with the folding of the carton, in accordance with Appellant’s
method (Specification 19). Claim 1 is illustrative of the claimed invention
and reads as follows:
1. A method of making reinforced paperboard
cartons comprising the steps of:
(a) advancing a web of paperboard along a
path, the web of paperboard having a width;
(b) progressively applying at least one
ribbon of reinforcing material to the advancing
web of paperboard to form a reinforced region for
the carton, the ribbon having a width less than the
width of the web of paperboard and an edge;
(c) scoring fold lines in the web of
paperboard, at least one of the fold lines extending
transversely to the reinforcing[ ]2 region and
crossing the edge of the ribbon of reinforcing
2 For consistency, “reinforcing region” should be “reinforced region.”
