Appeal No. 97-0951
Application 08/148,452
Thus, we have a fundamental problem with the rejection
because it finds that Wong teaches more than it appears to.
However, assuming, arguendo, that Wong did teach everything
except for the limitations of "said inverter circuits . . .
coupled between current limiting transistors" (e.g., the
inverter 58 in figure 2 is coupled between current limiting
transistors 75 and 77) and "means, including a current
regulator circuit, for providing a set of current levels in
the inverter circuits . . .," we find no motivation in
Banura to modify Wong to provide these features. The2
inverters in Wong are connected directly between the supply
voltage V and ground and the output is connected to the
DD
output V ; thus, Wong has a fixed current flow through the
O
inverters. There is no disclosure or suggestion in Wong to
use serially arranged current limiting transistors as
claimed.
Banura discloses a linear power regulator with a
MOSFET 80 arranged for connection between an input voltage
source V and a load. A difference amplifier 85 maintains a
i
Since we do not find bipolar transistors recited2
anywhere in claims 1, 3, or 14 we do not understand why the
Examiner states that Wong does not teach this feature.
