Appeal No. 1997-1505 Page 7
Application No. 08/580,778
We find that the specification (page 6) discloses that
the digital control logic means 30 locks the frequency of the
system. Figure 2a shows polysilicon laser fuses (dashed
lines) and resistors R1-R4. Claim 5, from which claim 7
depends, recites that the circuit arrangement for locking the
loop frequency is operatively coupled to the frequency
adjustment means. It is clear from claim 5 that appellant is
claiming the circuit arrangement for locking the loop
frequency as a separate element from the frequency adjustment
means. We find this to be understandable in light of
appellant’s specification and drawing. As shown in figure 1,
the divide by M circuit 26 and divide by N circuit 28 are
connected to the digital control logic means 30, which is part
of the frequency adjustment means. We therefore find that the
digital control logic means, for supplying signals to the
divide by M and divide by N circuitry, is part of the
frequency adjustment means, and not part of the “circuit
arrangement” as advanced by the examiner. Accordingly, the
rejection of claim 7 under 35 U.S.C. § 112, second paragraph,
is reversed.
