ethers from the condensation of alcohols with fluorinated
olefins.
The examiner does not refer to any specific knowledge of

teachings of the references themselves. See In re Rouffet,
supra. However, on this record, we fail to find any reason,
motivation or suggestion to combine the references in the
manner suggested by the examiner.
The examiner notes that Kricheldorf ‘83 concludes that
“the fluoride ion converts the trimethylsilyloxy group into a
phenolate ion which in turn attacks the activated fluorine-
carbon bond of the diphenyl sulfone” (Kricheldorf, page 2286,
and see also the answer, page 4, last paragraph). The
examiner then applies this teaching from Kricheldorf ‘83 (and
the secondary references in general) to the reaction disclosed
by the primary references, which involves the nucleophilic
displacement of a vinylic fluoride ion by an alkoxide ion
(answer, paragraph bridging pages 3-4, and page 5). However,
Kricheldorf ‘83, and the other secondary references in
general, only teaches that the cesium alkoxide or phenolate
