Appeal 2006-1305
Application 10/236,270
REJECTION UNDER 35 U.S.C § 103(a) OVER THE ADMITTED PRIOR
ART IN VIEW OF WATANABE AND DAUGHENBAUGH
Claims 1 and 3-20 are rejected under 35 U.S.C § 103(a) as
unpatentable over the admitted prior art (Specification 1-2) in view of
Watanabe and Daughenbaugh.
The Examiner finds:
The admitted prior art discloses that it is
conventional in the art to use ethylene vinyl acetate
copolymer based hot melt adhesives in case and
carton sealing operations for packaging food and
consumer goods. The admitted prior art teaches
that when these hot melt adhesives are used to
bond substrates such as polymer laminated
paperboard in case and carton sealing the bond
strength suffers unless a hot melt adhesive with
excellent heat and cold resistance is used.
[Answer 7.]
The Examiner then concludes:
It would have been obvious to one of ordinary skill
in the art at the time the invention was made to use
. . . the high heat and cold resistant ethylene vinyl
acetate copolymer hot melt adhesive taught by
Watanabe . . . [as modified by Daughenbaugh in
the prior rejection] to case and carton seal polymer
laminated paperboard with high bond strength.
[Id.]
We note that Appellants have not contested the Examiner’s reliance
on the admitted art. We also note that the arguments presented regarding
this rejection on pages 8 through 10 of the Brief are the same as the
arguments addressed in the prior rejection. We again find these arguments
unconvincing for reasons presented above.
