has a sufficient strength as a hose and a sufficient antistatic
function” (¶ [0131]).
13) Nishi discloses that a preferred fluororesin for use as the
inner layer is ETFE (¶ [0018]).
14) Nishi discloses that the thermoplastic resin of the outer layer
may be a polyamide, a polyester, or a blend thereof (¶ [0015]).
15) Nishi further discloses that the fluororesin of the inner layer
has the feature of melt adhesiveness with the thermoplastic resin of
the outer layer (¶ [0021]).
16) According to Nishi, this feature may be achieved by the
addition of a functional group to the fluororesin of the inner layer
(¶ [0023]).
17) Nishi teaches that “the adhesiveness-imparting functional
group is a group having reactivity or polarity and may, for
example, be a carboxyl group, a residue after dehydration
condensation of a carboxyl group (a carboxylic anhydride residue),
an epoxy group, a hydroxyl group, an isocyanate group, an ester
group, an amide group, an acid amide group, an aldehyde group,
an amino group, a hydrolyzable silyl group or a cyano group”
(¶ [0028]).
ANALYSIS AND CONCLUSIONS
The Examiner relies on Nishino for a disclosure of the invention as
claimed with the exception that Nishino fails to teach that the fluororesin of
the inner layer has a functional group. The Examiner notes that Nishi
