must have a solubility within the range of the claimed subject
matter or a solubility greater than the range set forth in the
claimed subject matter provided only that it is soluble in an
amount falling within the range of the claimed subject matter.
The compound must be capable of being deposited downstream of
a combustion chamber. However, this does not preclude the
compound from also being deposited elsewhere such as in a
combustion chamber. Finally, the compound must be capable of
functioning as at least one compound of a three way metal
catalyst, which catalyst effects the simultaneous oxidation of
carbon monoxide, unburned hydrocarbons and reduction of
nitrogen oxides. However, we find no requirement in the
claimed subject matter before us that the compound necessarily
perform all three catalytic functions. Accordingly, we will
now consider the individual rejections under section 102(b).
We will sustain the rejection of claims 1, 4, 5, 7, 16,
23 and 27 as anticipated by Lyons under 35 U.S.C. § 102(b).
Lyons is directed to a gasoline additive. See Demonstrations,
page 3, column 1. The additive, an organo-metallic compound,
is preferably soluble in the motor fuel, and effective
catalytically in increasing the efficiency of the fuel
