Appellants have relied upon the following reference in
rebuttal of the examiner’s rejection:
Morrison et al. (Morrison), Organic Chemistry, 3rd ed., 821-
826, Allyn and Bacon, Inc., Boston (1973)
Claims 13 through 15, 19, 21/19, 22/21/19, 23/22/21/19
and 24/22/21/19 stand rejected under 35 U.S.C. § 103 as
unpatentable over EP ‘114, GB ‘477, and/or Gash in view of
Kricheldorf ‘83, Kricheldorf ‘84 and/or Saunders (answer, page
3). We reverse this rejection for reasons which follow.
OPINION
The process of appealed claim 13 requires the
polycondensation of a silyl ether and a fluorinated olefin in
the presence of a suitable catalyst at a temperature range of
-50 to 120EC. to form a partially fluorinated ether.
