F 26. Par& 426 says that there is a need for a method of enhancing the volatility of the volatilizable
substances and for selectively separating the volatile component. P. Ex. 2002, col. 3). 11. 34
47.
F 27. Par& 426 addresses the volatility problem by subjecting the substance to microwave radiation
to enhance the volatility of the desired substance. P. Ex. 2002, col. 2, 11. 13-23.
F 28. Par6 426 describes a process in which a material containing the volatile component is placed
in a container which is then sealed with a selective semipermeable membrane, microwaves
are applied to effect volatilization and the desired volatile components are separated by
passing them through a semi-permeable membrane. P. Ex. 2002, col. 3,11. 43-58.
F 29. The volatilization procedure is said to be preferably performed in a sealed container. P. Ex.
2002, col. 2,11. 23-27.
F 30. Par6 426 says the semipermeable membrane separates the volatile components from the
contents of the container. P. Ex. 2002, col. 6,11. 21-23.
F 31. Par6 426 also describes the use of a sorbent to absorb and separate the volatile components
released by the application of microwaves. P. Ex. 2002, col. 4,11. 37-40.
F 32. The particular sorbent is said to be dependent upon the particular volatile material of interest.
P. Ex. 2002, col. 8,11. 25-M
F 3' ). Par6 426 notes that using the microwave techniques of the invention, volatile components
for a variety of uses may be generated more easily with greater efficiency while allowing for
less error and contamination. P. Ex. 2002, col. 2,11. 13-22.
F 14. Example 2 of Par6 426 states, in relevant part:
Fresh sage, of 80% moisture content, obtained from Saint-Jean-sur-Richelieu,
Quebec, Canada, was chopped coarsely into pieces and subjected to
conventional purge and trap analysis as well as to conventional headspace
analysis. A portion of the same material was inserted into a container. The
container was sealed by a cover through which an orifice had been made. A
commercially available sorbent, in an appropriate container, was fitted from
the inside of the container to the orifice thus creating an hermetic seal. The
container and its contents were then treated by exposure to microwave
radiation for 90 seconds so as to severely disrupt the equilibrium that existed
between the solid plant material and the gases around it. The sorbent was then
eluted and the eluate analyzed by gas chromatography. The results of the
