(b) thereafter applying a second coating as a
coverlay upon said initial film, said second coating
consisting essentially of an amorphous fluorinated
ethylenic-cyclo oxyaliphatic substituted ethylenic
copolymer and having the structural repeating unit:
- (CF - CF ) (-CF - CF) -2 2 n m
* #
O O

CF CF 3 3
wherein “m” and “n” represent integers providing a
molecular weight of between about 230,000 and 500,000,
with the values of “m” and “n” providing a copolymer
with a glass transition temperature ranging from
between about 160E C. and 240E C., the second coating
being applied to said initial film layer in castable
liquid state, and with the composite film having a
thickness greater than about 2 mils.
The references relied upon by the examiner are:
Effenberger et al (Effenberger) 4,883,716 Nov. 28, 1989
Vassiliou et al (Vassiliou) 4,016,125 Apr. 5, 1977
Boling et al (Boling) 5,008,129 Apr. 16, 1991
All the claims stand rejected for obviousness under 35 USC
§ 103 in view of Effenberger taken in combination with Vassiliou
and Boling.
Based on the record before us, we agree with appellants that
the combination of references applied by the examiner against the
claims is unsound. To wit, the examiner has used the instant
claims as a blueprint for combining the references which amounts
