Appeal 97-1554
Application 08/495,593
17. The examiner has rejected claims 1-5 and 7 as
being unpatentable under 35 U.S.C. § 103 over Kummer and Rath.
Kummer
18. Kummer describes fuel or lubricant compositions
which include a Component A containing polyisobutyl amines,
optionally with polybutyl amines (col. 1, lines 39-51).
19. Component A is made by a hydroformulation
process (col. 4, lines 16-25).
20. According to Kummer, use of Component A prevents
the formation of deposits in the intake system of internal
combustion engines (col. 1, lines 35-38).
21. Further according to Kummer (col. 5, lines 62-
68):
The novel fuel or lubricant composition has a number
of advantages over the prior art, for example the fact
that the compounds in question are saturated compounds,
no corrosion problems occur, synthesis is more economical
and causes less environmental pollution, and the products
are not contaminated by chlorine or bromine.
