the examiner’s position that its meaning is not known to those
skilled in the art.
Further, the examiner, referring to claims 18 and 19,
argue (Answer, page 6) that:
It is not clear what are the reactive groups of
the polyimide precursor. It is also unclear on what
appellant bases the weight of the reactive group.
For example if the reaction takes place at a
carboxyl oxygen is the weight of the reactive group
only the reacting oxygen, or does it include the
carboxyl carbon and any other substituents attached
to the carboxyl carbon? If the reactive group is a
sidechain of the polyimide precursor does the weight
include the entire sidechain or just the atoms which
undergo chemical reaction?
The examiner, however, has not demonstrated that reactive
groups of the polyimide precursors defined at page 4 of the
specification are not known to those skilled in the art. In
fact, the examiner recognizes that carboxylic acid groups of
the polyimide precursors (the polyamic acids) are reactive
groups. See Answer, page 10, together with specification,
page 4. Since the weight of reactive groups employed is
dependent on the types of reactive groups employed (carboxylic
acid groups), we find that one of ordinary skill in the art is
fully aware of "what appellant [sic, appellants] bases [sic,
base] the weight of the reactive group."
