doping. (Br. at 11.)7 According to Jackson, "[t]ransitions between
detectable memory states in an organic-polymer layer do not imply changes
in chemical bond or in organic polymer doping. Such transitions may result
from accumulation of charge, changes in polymer orientations, and from
many other changes that do not involve changing chemical bonds or organic-
polymer doping." (Br. at 13.) Jackson argues further that "it is
accumulation of charge, rather than changes in chemical bonds and changes
in organic polymer doping, to which Stasiak explicitly attributes the
electronic properties of his memory cell." (Id.)
Jackson does not direct our attention to any definition in the
specification of what is meant by "changes in chemical bonds". Our review
indicates that no special definition has been provided. We therefore
interpret this limitation in the broadest reasonable manner consistent with
the disclosure. As the Examiner has shown via the Gold reference, chemical
reactions involve changing at least one chemical bond in a molecule.
Stasiak, in paragraph 23, teaches that dopants are useful additives to
polymers suitable for its invention. In Stasiak's words, dopants are
compounds that promote charge transport via a "one electron oxidation or
reduction process between neutral functional groups and their charged
derivatives." Applying the broadest reasonable interpretation of the term
"changes in chemical bonds" consistent with the disclosure, we have no
difficulty concluding that changes introduced by the dopant materials
disclosed by Stasiak change chemical bonds under the influence of some
7 Jackson does not dispute the Examiner's findings that Stasiak discloses the
other limitations of claim 1, and we hold such arguments to have been
waived.
