F 54. The microwaved mixture was then centriftiged to separate the liquids and solids. P. Ex.
2003, p. 299, Summary.
F 55. The liquid was injected into a chromatographic column and the results compared with the
results of conventional (non-microwave) techniques. P. Ex. 2003, pp. 301-3305.
F 56. The authors conclude that microwave assisted extraction was more effective than the
conventional methods and resulted in savings of time an energy. P. Ex. 2002, p. 305.
F 57. Ganzler does not expressly disclose intermittently applying reduced pressure.
4) The Wennerstrum Patent (Wennerstrum)
F 58. The Wennerstrurn Patent relates to a method and apparatus for the batch drying using a
microwave vacuum system. P. Ex. 2004, col. 1, 11. 7-13.
F 59. Wermerstrurn teaches a method including the steps of placing the product to be dried in a
container, placing the container and product into a chamber, pulling a vacuum in the chamber
and applying microwaves to the product until drying is completed. P. Ex. 2004, col. 13,
11. 11-38.
F 60. The vacuum in the chamber is said to be maintained at a constant reduced pressure using a
dual.valve or a diaphragm system. P. Ex. 2004i col. 7,11. 42-68.
F 61. The valves are operated so as to consistently maintain the desired level of vacuum in the
chamber. P. Ex. 2004, col. 7,11. 42-68.
F 62. Wennerstrurn does not expressly disclose intermittent application of reduced pressure.
C. Pari's Position on Intermittent Application of Reduced Pressure
F 63. Pard argues that intermittently applying reduced pressure or vacuum is inherent in the
teachings of Example 2 of the Par6 patents and is also inherent in the Ganzler and
Wermerstrum disclosures. Paper 40, p. 9.
F 64. Pard asserts that both Pard patents and Ganzler employ "conventional microwave ovens" to
provide microwaves. Paper 40, p. 20-2 1.
F 65. Par6 asserts that it is well known that conventional microwave ovens supply microwaves in
pulses, i.e. in repeated on-cycles and off-cycles. Paper 40, p. 20.
F 66. Par6 argues that the Par6 patents and Ganzler teach treating samples in sealed containers with
alternating periods of microwave exposure and non-exposure. Paper 40, pp. 20-21.
