respectively and vice versa. The rising signal edges of OSC
of Lofgren
(perhaps the claimed first type edges or second type edges)
and the delayed rising signal edges of DOSC (perhaps the
claimed second type edges or first type edges) are compared in
Lofgren. Phase changes then occur based upon this comparison.
Furthermore, in the alternative, as urged by the
examiner, separate or different or independent circuit
elements (pump up and pump down, as well as VCR and VCN
signals in the figures) in Lofgren control the rising and
falling edges of clock OSC and of delayed clock DOSC. Again,
claim 21 does not recite that the first type signal edges are
delayed independently of the delay associated with the second
type edges only that “said first type signal edges are delayed
independent of said second type edges.”
We have reconsidered our decision of June 16, 1997, in
light of appellant’s arguments and appellant’s request for
