This definition explains why the claimed complex has five
bonds on the linking carbon atom. The examiner’s reliance on
the March reference, however, does not negate this teaching.
The March reference, for example, shows oxygen having three
bonds even though it typically has a valence of two. See page
162. The March reference also indicates that "hydrogen
bonding is not present" in every hydrogen containing compound.

The examiner also argues that "the specification does not
teach what groups on the polyimide precursor are the reactive
groups of the polyimide precursor (emphasis supplied)." See
Answer, page 5. In so arguing, the examiner again ignores the
state of the prior art, as well as the relative skill of one
of ordinary skill in the art. In this regard, we also note
that the examiner acknowledges at page 8 of the Answer that
carboxylic acid groups, although not mentioned in the
specification, are the reactive groups of the polyimide
precursors (polyamic acids).
