considered and, here, should have been. As mandated by
the court in Rinehart, 531 F.2d at 1052, 189 USPQ at 147
and Piacecki, 745 F.2d at 1742-43, 223 USPQ at 788, we
have evaluated all the evidence anew.
Experiment I compares the effect pseudo-boehmite and
gamma-type alumina have on catalytic activity. Keeping
all other constituents and conditions the same, the
gamma-type alumina of Example 1 of the supporting
specification was substituted for pseudo-boehmite. The
results show that
pseudo-boehmite increases the temperature at which 50% of
the initial CO is converted to CO2 by 32°C. This is
indicative of decreased efficiency for catalysts
employing Brunelle’s boehmite.
Experiment II is directed at Koberstein, which
teaches atomizing a refractory oxide of the type claimed,
although only in combination with a cerium salt. It
compares results for a catalyst prepared by atomizing the
claimed suspension
of cerium and ferric nitrates and gamma-type alumina
against a catalyst prepared the same way but, as
Koberstein teaches, adding the iron salt through a post-
