Appeal No. 96-1247
Application 08/115,662
skew on an ongoing basis. Deyhimy discloses in column 2, line
61, through column 3, line 15, that the preferred
embodiment of their invention is to provide delay blocks.
The delay elements are switched into or out of the master
clock output path in a binary-weighted group, thereby
minimizing the required number of switching means
necessary to obtain any desired delay. The skew between each
of the master clock signals can be measured and the switching
means can be employed to reduce the skew to a minimum. Thus,
Deyhimy solves the skew problem, not by designing the PC
circuit boards such that the interconnections minimize skew
but instead by measuring the skew on an ongoing basis and
switching in or out delay elements on an ongoing basis to
counteract the skew. Thus, Deyhimy does not provide any
suggestion, incentive or reason to one of ordinary skill in
the art to provide connections at the circuit board such that
skew is minimized between logic elements as claimed by
Appellant's independent claims 1 and 14. There- fore, we
will not sustain the Examiner's rejection of claims 1 through
10
