Appeal No. 1999-0207
Application No. 08/477,560
According to appellants, the invention is directed to
polymeric blends comprising a mixture of at least one crosslinkable
oligomer and at least one compatible, noncrosslinking polymer
from a different chemical family (Brief, page 2). A copy of
illustrative claim 14 is reproduced below:
14. An advanced composite blend comprising a mixture of
at least one crosslinkable oligomer and at least one compatible,
noncrosslinking polymer from a different chemical family, wherein
the oligomer comprises two ends, each of which comprises two
unsaturated, crosslinkable end-cap moieties and wherein, prior to
curing, the oligomer has an average formula weight less than that
of the polymer.
Claims 14 through 16 stand rejected under 35 U.S.C. § 112,
first paragraph, “because the specification, while being enabling
for those cross-linking oligomers disclosed in the specification
page 6, line 12-page 8, line 5, does not reasonably provide
enablement for tetrakis isocyanates end caps as to the oligomer.”
Answer, page 3. We reverse the examiner’s rejection essentially
for the reasons set forth in the Brief, Reply Brief, and the
reasons below.
OPINION
Claims 14 through 16 stand rejected by the examiner for
failure to fulfill the enablement requirement of 35 U.S.C. § 112,
namely because the specification does not enable any person skilled
in the art to make and use the invention “commensurate in scope
