Application No. 09/725,428
“determining with a second detector . . . at the exit of the
purification system . . . . ” Significantly, the waste gas
purification system of claim 1 comprises a combustion chamber
followed by a sorbtion chamber.
Thus, in order to comply with the first and second detector
steps recited in the appealed independent claim, the method of
Rossin would have to be modified to include use of a first
detector for measuring the type and amount of selected harmful
substances in the process waste gas before the waste gas enters
patentee’s catalytic oxidation chamber (which the examiner
analogizes to the here claimed combustion chamber). However, the
Kisters reference contains no teaching or suggestion of using a
detector for measuring substances in process waste gas before the
waste gas enters a waste gas purification system which comprises
a combustion chamber followed by a sorbtion chamber as required
by the claim before us. Rather, consistent with the examiner’s
discussion of this reference and the obviousness conclusion based
thereon, Kisters’ most upstream use of a detector occurs before
the waste gas enters his absorber (e.g., see figure 1 and the
specification disclosure relating thereto). Therefore, even if
the teachings of Rossin and Kisters were combined, the result
would be a method in which first detector measuring would occur
