20 under 35 U.S.C. 103.
Finally, we turn to the rejection of claim 4, with which
claim 15 will stand or fall. Claim 4 spells out, in detail, a
data register file and its connections to the ALU. Here, while
the examiner initially appears to have presented a reasonable
analysis [answer-pages 5-6] with regard to the rejection of
claim 4 under 35 U.S.C. 103, upon further analysis we find the
rejection lacking and will not sustain it or the rejection of
claim 15 under 35 U.S.C. 103.
The examiner says that Ing-Simmons discloses a variety of
data registers including a data register file and a register
destination (via Mux element 3309) to store the output of the
ALU. Further, Chu discloses the use of registers in Figure 1
and it is well known to use registers as temporary storage
devices. While, at first blush, the examiner’s comments seem
