Appeal No. 2002-1882
Application 09/756,383
of rhodium acetylacetonate in combination with a platinum
compound, regardless of whether the platinum compound is an
acetylacetonate.
The appellants argue that there is no disclosure of using
Bower’s platinum group compounds with catalytic converters
(brief, page 6). The teaching by Bowers that the gasoline
preferably is unleaded (col. 4, lines 26-27) indicates that the
platinum group compounds are capable of being added to gasolines
which are to be combusted in engines having catalytic converters.
The appellants argue that there is nothing which suggests
that a combination of a fuel-soluble organoplatinum compound and
rhodium acetylacetonate would be effective in so many categories
as shown in the appellants’ example (brief, page 6). Use of the
appellants additive in the four automobiles of the appellants’
example (specification, page 7, line 27 - page 8, line 3) is not
required by the appellants’ claim 1.
For the above reasons we conclude that the appellants’
claimed invention would have been obvious to one of ordinary
skill in the art over the applied prior art.
