Appeal No. 1999-0260
Application 08/571,064
For each ground of rejection which appellant contests
and which applies to a group of two or more claims, the
Board shall select a single claim from the group and
shall decide the appeal as to the ground of rejection
on the basis of that claim alone unless a statement is
included that the claims of the group do not stand or
fall together and, in the argument under paragraph
(c)(8) of this section, appellant explains why the
claims of the group are believed to be separately
patentable. Merely pointing out differences in what
the claims cover is not an argument as to why the
claims are separately patentable.
We will, therefore, consider this group of Appellants'
claims as standing or falling together, and we will treat claim
10 as a representative claim of that group.
We first address the claimed invention. We find that the
preamble of claim 10 is directed to a power enabling method for
controlling the supply of operating power from an information
processing apparatus to a detachable input/output device.
Appellants' admitted prior art figure 11 shows control of
operating power Vcc and Vpp from a computer to a detachable PC card
(60), all the limitations of the preamble.
The first subparagraph of this claim recites "detecting
whether or not there exists a power supply abnormality." Price
teaches34 the implementation of current sensing circuitry (46) to
detect excessive line current supplied to line interface
