Appeal No. 2001-2094
Application 09/203,894
The appellants also acknowledge that “JP 57115493 (July 17,
1982) discloses 2,2,4-trimethyl-1,2-dihydroquinoline polymer as a
useful antioxidant for lubricating oils” (specification, page 1,
lines 25-26). The examiner indicated, by initialing the
appellants’ information disclosure statement (filed December 2,
1998, paper no. 2), that this reference has been considered.
However, we do not find in the file an English translation, or
even an English abstract, of this reference, and the examiner has
not addressed on the record the relevance of this reference. The
examiner should obtain an English translation of JP 57115493 and
the examiner and the appellants should address on the record
whether it would have been obvious to one of ordinary skill in
the art to combine the 2,2,4-trimethyl-1,2-dihydroquinoline
polymer lubricating oil antioxidant disclosed therein with a
secondary diarylamine lubricant oil antioxidant which the
appellants have acknowledged to be well known.
