compounds and peroxides. It is evident from the disclosures of
Kobayashi and Döscher that peroxides and azo compounds are known
catalysts for free-radical reactions. Also, Kobayashi discloses
using phosphorous trichloride as a catalyst which is analogous to
appellant’s disclosed example of phosphorous pentachloride.
Moreover, we do not find any evidence of record from which to
conclude that appellant’s “free-radical generators” are inclusive
of all means for generating free-radicals, i.e., catalysts, UV
radiation and thermal. Appellant’s “free-radical generators” are
limited to compounds that generate free-radicals. Thus, we find
that one of ordinary skill in the art would have understood the
expression “without the addition of free-radical generators” to
mean without the addition of free-radical catalyst compounds such
as phosphorous pentachloride, sulphuryl chloride, sulphur
chlorides, iodine, peroxides and azo compounds, to the reaction.
It is also evident from these disclosures that if free-radical
generator catalysts are employed, the catalysts are explicitly
set forth in the examples.
For the reasons given above, we find that the expressions
“without ultraviolet radiation” and “without the addition of
free-radical generators” do not introduce new concepts and
violate the written description requirement of the first
