Appeal No. 96-0088 Application No. 08/038,426 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 11Page: Previous 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 NextLast modified: November 3, 2007
