From these teachings, one of ordinary skill in the art
would recognize that what is critical is the geometry of the
lens group and not the positive or negative refracting powers
of the lens group. We further note that Tokumaru's zoom lens
system also has similar four lens grouping having the same
geometry. Therefore, given the teachings of Umeda, one of
ordinary skill in the art would have been led to applying
Umeda's displacement means to the third lens group to thereby
cause the third lens group to be decentered in a direction
substantially perpendicular to the optical axis. We further
note that Sato and Kitagishi provide further support to
buttress this position. Therefore, we will sustain the
Examiner's rejection of claims 1 through 7.
Regarding claim 8, Appellant argues on page 10 of the
brief that claim 8 recites that the claimed zoom lens also
includes a stationary flare stop which is arranged around the
optical axis and shields unnecessary rays upon movement of
said third lens group in the direction substantially
perpendicular to the optical axis for vibration reduction.
Appellant argues that the Examiner's contention that Tokumaru
