argument simply fails to take into account this clear teaching
on the part of the Nader reference.
As also indicated supra, we observe that the Kvakovszky
reference does not require distillation prior to
polymerization. Accordingly, we read the Kvakovszky reference
to teach polymerization of the resulting substituted 4-
hydroxystyrene, without distillation. This reading is
especially appropriate since the Kvakovszky reference
describes forming a product containing the same level (84%) of
a substituted 4-hydroxy-
styrene, with or without distillation. Compare examples 3 and
4. Appellant has not demonstrated by objective evidence that
the exemplified organic phase having a substituted 4-hydroxy-
styrene (example 3) in the Kvakovszky reference contains
alkali metal impurities. Nor has appellant demonstrated by
objective evidence that the amount of alkali metal impurities
in the above-mention organic phase is detrimental to forming a
photoresist material.
On this record, we agree with the examiner that the
claimed subject matter as a whole is anticipated by the
disclosure of Nader or Kvakovszky. Thus, we affirm the
