Appeal 2007-2893
Application 10/818,885
ANALYSIS:
The Examiner finds that Park teaches a pot having a shell with a first
heat-conductive plate, a second heat-conductive plate, and a sealed vertical
cavity (Answer 3). The Examiner finds that the vertical space of Park’s pot
is partially filled (up to about 55-90% by volume) with a heat conduction
medium, such as silicon oil (id.). According to the Examiner, “it would have
been an obvious matter of design choice to a person of ordinary sill [sic] in
the art to have the sealed cavity of Park filled to 95 percent with silicon oil. .
.” (id.).
Park teaches a cooking utensil that comprises
an outer shell having an opening; an inner shell disposed inside
the outer shell through the opening, forming wall and bottom
spaces between the outer and inner shells, wherein the . . . wall
space is formed substantially along the height of the inner shell,
wherein the wall and bottom spaces contain at least partially a
heat conductive medium; and a heating coil arranged on the
bottom of the outer shell for heating the outer shell of the
cooking utensil.
(Park, col. 2, l. 66 – col. 3, l. 8, emphasis added.) As Park explains, “[t]he
cooking utensil includes a built-in controller arranged on [the] outside of the
outer shell and connected to the heat coil to control [the] amount and period
of heat provided to the cooking utensil” (Park, col. 3, ll. 9-12). We do not
find, and the Examiner has failed to identify, a teaching in Park to suggest
that Park’s cooling utensil can be adapted for placement directly on an open
flame or burner. In this regard, we note that the Examiner does not address
the requirement in the body of Appellant’s claim that the second heat-
