are the controlled decomposition oxidation unit of claims 2, 4
and 12. See Figure 1, and accompanying description in the
specification, page 3 lines 17-18. Coupling of the input to
receive exhaust gas at the point of generation required by
claims 3 and 13 is likewise disclosed in Figure 1 and
discussed at page 4, lines 2, 3 and 6. The additional input of
claim 5 is also taught in Figure 1, gas lines (12), page 3,
lines 19-20 of the specification. Based on the above, we
conclude that each of these features required by the claimed
subject matter are disclosed in the admitted prior art.
The examiner relies upon the secondary references to Yeh
and Kito for disclosure of the claimed submicron filter
assembly. Both Yeh and Kito disclose the additional treatment
of gases with electrostatic forces, functioning as
electrostatic filters as required by the claimed subject
matter of claims 6, 14, and 21, in order to remove very small
particles remaining in said gas.
We essentially agree with the examiner’s conclusion that,
“it would have been obvious to one of ordinary skill in the
art to provide an electrostatic filter of Yeh or Kito
downstream of the CDO unit in order to prevent polluted gases
