F 67. The alternating periods of exposure and non-exposure are argued to result in alternating
periods of heating and cooling. Paper 40, pp. 20-21.
F 68. Par6 then asserts that the "ideal gas equation" predicts that the pressure in the containers
described in the Pard patents and Ganzler will increase due to the heating and decrease
during cooling when the heat is removed. Paper 40, p. 20.
F 69. The ideal gas equation may be represented by the formula
PV--nRT
where P represents gas pressure, V represents the volume of the gas, n represents the amount
-the number of moles- of gas, R is the universal gas constant and T is the absolute
temperature of the gas.
F 70. The ideal gas equation predicts that for ideal gas systems that if the volume and the amount
of an ideal gas is held constant -as would be the case in a sealed container- the pressure of
the ideal gas will increase proportionally to an increase in temperature of the gas.
F71. With respect to the Par6 patents, Pard specifically argues:
Both Par6'426 or Parư'947 employ conventional microwave ovens to supply
microwave energy to release volatiles in fresh sage in a closed container
(Example 2). As is well known in the art, conventional microwave ovens
supply microwave energy in pulses (i.e., effectivity an on-off cycle that is
repeated throughout the treatment period). During the "on-cycle" of the
microwave energy, the temperatures of both the contents in the container and
the container itself will rise. During the "off-cycle," the temperatures will, of
course, fall since no heating energy will be supplied to the container or its
contents. One of ordinary skill in the art, using the well known ideal gas
equation (Whitten et al.), namely
PV = nRT,
will know that as the temperature of the contents and container are increased
during the "on cycle," the pressure must increase since the volume and
number of moles remain essentially constant. Likewise, one of ordinary skill
in the art will know that as the temperature of the contents and the container
fall during the "off-cycle," the pressure must also fall. Thus, the contents and
the container are exposed to intermittently applied reduced pressure within
the enclosure during the application of microwave energy.
