Appeal 2007-1395
Application 10/328,115
detergents in compositions comprising alkylene oxide-adducted hydrocarbyl
amide fuel additives (Answer 5).
Appellant contends that Boehmke describes a fuel composition
comprising water and, as such, Lin would not have suggested to a person of
ordinary skill in the art to utilize a nitrogen containing detergent in the fuel
composition. We do not agree. Lin is evidence that detergent additives for
fuel compositions are known by persons of ordinary skill in the art. The
Boehmke and Lin references describe fuel compositions comprising similar
alkylene oxide-adducted hydrocarbyl amide fuel additives. Thus, a person
of ordinary skill in the art would have reasonably expected that nitrogen
containing detergents would have been suitable for the fuel composition of
Boehmke due to the similarity of components in the fuel compositions of
Boehmke and Lin.
As a final point with respect to the § 103 rejections, we note that
Appellant bases no argument upon objective evidence of nonobviousness,
such as unexpected results.
For the foregoing reasons and those presented in the Answer, we
affirm the rejection.
ORDER
The Examiner's decision rejecting claims 1 and 11-19 is affirmed.
