Ewen has not explained how or why the disclosure in Ewen JACS
describes subject matter defined by Claims 4-6, 8, 12-26,
and 31-37 of Dolle Application 08/147,006, or reasonably would
have suggested the subject matter defined by Claims 4-6, 8,
12-26, and 31-37 of Dolle Application 08/147,006 to persons
having ordinary skill in the art, either alone or in
combination with the teaching of Ewen et al., U.S. 4,892,851.
However, as did the APJ (Paper No. 54, pp. 8-13), we hold
that Claims 27-30 (Appendix E) of Dolle Application 08/147,006
are not limited to metallocene compounds and catalysts which
are useful exclusively for preparing “syndio-isoblock polymers
having molecular chains in which syndiotactic and isotactic
sequences are present and the sequence length is 3 to 50
monomer units” (Claim 32). Claims 27-30 are directed to
metallocene compounds and catalysts which are unlimited as to
their utility, e.g.,
(1) metallocene compounds and catalysts for use in preparing
hemiisotactic polymers described in Ewen, U.S. 5,036,034,
which are not “syndio-isoblock polymers having molecular
chains in which syndiotactic and isotactic sequences are
present and the sequence length is 3 to 50 monomer units”, or
