“within a maximum propagation delay” and that the first
portion of a component has only first voltage signal paths of
devices “which operate below the maximum propagation delay”
when the devices are operated at a first voltage while a
second portion of the component has only second voltage signal
paths of devices which “do not operate below the maximum
propagation delay” when the devices in the signal paths are
operated at the first voltage, wherein devices of the second
portion of the component are operated at a second, higher
voltage, decreasing the propagation delay through the signal
paths. Independent claim 9 has similar recitations.
Gregor says nothing about a “maximum propagation delay”
or about various portions of components operating at voltages
which affect propagation delays, as claimed. Gregor’s only
concern about propagation delays is that the interface circuit
described therein introduces “minimal propagation delay”
[column 2, lines 9-11].
The examiner’s treatment of these specific claim
limitations is to contend that “since elements 19 and 20
receive a higher supply voltage, they will inherently operate
above a ‘maximum propagation delay.’ The ‘maximum propagation
