isotactic and syndiotactic sequences. To the extent that
Dolle’s claims might be broadly interpreted to cover
impossibilities, the broad interpretation would be
inconsistent with conventional knowledge in the art and the
teaching in Dolle’s specification as a whole.
We conclude that persons skilled in the art would have
recognized that Dolle’s claims do not cover impossibilities.
Syndiotactic and isotactic sequences together with, for
example, ethylene as the olefinic monomer, are to be
interpreted in the context of copolymerization processes.
When polymerizing internal olefinic monomers, syndiotactic and
isotactic sequences are defined relative to the asymmetric
carbon atoms in the polymer prepared. Ewen’s arguments and
Dr. Gauthier’s view that Dolle’s claims read on
impossibilities are unreasonable because they are inconsistent
with the common knowledge and good sense of persons skilled in
the art. Persons having ordinary skill in the art are
presumed to think along the line of conventional wisdom.

persons skilled in the art would have read the words and
phrases of the processes Dolle claims so to read on
