isoblock polymers having molecular chains in which
syndiotactic and isotactic sequences are present and the
sequence length is 3 to 50 monomer units, Dolle states
(Application 08/147,006, spec., pp. 11-12, bridging para.;
emphasis added):
The monomers polymerized or copolymerized are olefins of
the formula RCH = CHR’ in which R and R’ are identical
or different and are a hydrogen atom or an alkyl radical
having 1 to 14 carbon atoms or R and R’ combine with
the carbon atoms joining them together to form a ring.
Examples of olefins of this type are ethylene, propylene,
1-butene, 1-hexene, 4-methyl-1-pentane, 1-octene,
norbornene, norbornadiene or compounds of the type
1,4,5,8-dimethano-1,2,3,4,4a,5,8,8a-octahydronaphthalene,
2-methyl-1,4,5,8-dimethano-1,2,3,4,4a,5,8,8a-octahydro-
naphthalene, 2-ethyl-1,4,5,8-dimethano-1,2,3,4,4a,5,8,8a-
octahydronaphthalene or 2,3-dimethyl-1,4,5,8-dimethano-
1,2,3,4,4a,5,8,8a-octahydronaphthalene. Preference is
given to propylene, 1-butene and norbornene.
We presume that persons having ordinary skill in the art would
have read Dolle’s disclosure as a whole with no less than the
conventional wisdom in the art. Standard Oil Co. v. American
Cyanamid Co., 774 F.2d 448, 454, 227 USPQ 293, 298 (Fed. Cir.
1985). The misnomers on page 3 of Dolle’s specification would
have been apparent to persons having ordinary skill in the art
in light of the further instruction on pages 11-12.

made by polymerizing or copolymerizing olefin monomers in
