III. Claims 1-4, 6-13 and 15-21 stand rejected under 35 U.S.C. §
§ 103 as being unpatentable over Henton in view of Lee.
The examiner points to Henton as showing a composition
comprising a liquid bisphenol A epoxy resin pre-reacted with
bisphenol A (col. 3, lines 2-3), a core/shell polymer (col. 6,
lines 29-31), a hardener (col. 6, lines 41-43) and fillers (col.
2, line 53). The examiner indicates that Henton does not show
the claimed anhydride hardener and he relies upon Lee to show
alicyclic carboxylic anhydrides with amine accelerators such as
benzyldimethyl amine (Table 12-6) as a hardening system for epoxy
resins. The examiner has reasoned that one of ordinary skill in
the art would have found it obvious to harden the Henton epoxy
resins with the hardeners of Lee since Henton himself
acknowledges the use of such hardeners from Lee in order to
attain the proper balance of high temperature hardening without
undue weight loss.
In making this rejection, the examiner has taken the
position that components a) and d) of the instant claim are
satisfied by the preadvanced diglycidyl ether because the claims
