of some of these elements is unclear to us and the examiner
has not satisfactorily explained the correspondence. For
example, it is unclear to us how Blackard’s Figure 9, showing,
inter alia, a RAM, VIDEO, ROM and BIOS segments, corresponds
to the claimed plurality of “pseudo device drivers” with each
driver corresponding to a first system input/output device.
It is also unclear how the simulator 10 of Blackard’s Figure 1
corresponds to the claimed “emulator level interposed between
the second system user level process and a kernel level.”
Further, without identifying anything specific, the examiner
denotes Blackard’s “hardware and memory units of Figure 1"
[top of page 4 of the principal answer] as corresponding to
the claimed “second system hardware platform” which includes a
plurality of I/O devices, each one corresponding to a kernel
process, and wherein each combination of a pseudo device
driver, a corresponding kernel process and a corresponding
second system I/O device executes in a second system process
and emulates the operations of a corresponding first system
I/O task and corresponding I/O device. These last seven lines
of claim 1, for example, include many structural and
functional limitations. As such, it appears to us that the
