Appeal No. 2002-1850
Application 08/288,574
optional biaxially stretching step, the Korlatzki reference, like
appellant (specification, page 9; Fig. 8a), expressly teaches a
multi-layer casing of polyurethane (highly elastic) and PVDC (gas
impermeable) (column 3, lines 2 through 6, and column 5, lines 12
through 17 and 40 through 52) which lies taught and absolutely
wrinkle-free against food material content (column 6, lines 34
through 36).
In light of the above findings relative to the materials and
characteristics of the multi-layer casing of Korlatzki, we
determine that the Korlatzki patent responds to all features of
the packaging envelope in combination with formable meat set
forth in appellant’s claim 1, i.e., the casing of Korlatzki is
capable of and would be expected to stretch immediately before
and upon placement of formable meat therein, the casing would
spontaneously contract after placement of meat and automatically
force out air between the casing and the meat, and the casing
would force the formable meat into a nearly circular cross-
section shape.
It is for the above reasons that the anticipation rejection
of claim 1 is sustained.
