Appeal No. 95-2830
Application No. 07/967,617
teaching of equivalency by Pedrazzi of dioxazine compounds
optionally having bridging groups present, of the formula
(Y - NR) wherein n = 0 or 1. This bridging group corresponds1 n
to the teachings of the primary reference, Yokogawa, having
the corresponding bridging group W-NR , when n = 1, and
2
corresponds to the claimed invention when n = 0.
However, Pedrazzi fails to establish the equivalency of
the bridging group being either present or absent for the
purposes and compounds of the instant invention. There is no
motivation found in either Yokogawa or Pedrazzi why one having
ordinary skill in the art would choose to exclude an internal
group, i.e. the W-NR - of Yokogawa, based upon the teachings
2
of Pedrazzi.
The examiner states in his Answer, pages 3 and 4, that
the secondary reference to Pedrazzi teaches that, "in this art
of triphendioxazine fiber dyes, the diamine and amine type
bridge between the TPD core and a fiber reactive group are
considered functionally equivalent." A careful reading of
Pedrazzi does not support the examiner's position. The Z
group in Pedrazzi serves the function of being an internal
triazinyl bridge between two chromophore containing groups.
