facie case. It is the burden of the Examiner to establish why
one having ordinary skill in the art would have been led to
the claimed invention by the reasonable teachings or
suggestions found in the prior art, or by a reasonable
inference to the artisan contained in such teachings or
suggestions. In re Sernaker, 702 F.2d 989, 995, 217 USPQ 1, 6
(Fed. Cir. 1983).
The Examiner cites Wong as teaching the claimed
invention except for:
(a) the feature where a first control signal
source provides a first control signal responsive to
the first phase detector output signal when the
phase difference is less than a single cycle, and
where a second control signal source provides a
second control signal responsive to the second phase
detector output signal when the phase difference is
greater than a single cycle (Answer, page 5.)
The Examiner then incorporates the control means (SPED, Figure
2) of Koskowich to provide a first control signal source (150,
152
of Koskowich) and the second signal source (160, 162 of
Koskowich) in the multi-cycle phase detector taught by Wong
(Answer, page 6).
