1200-b, 1200-c and 1200-d for relaying the communication among the portable
communication devices; switching devices 1300-a and 1300-b for switching connections
among the radio base stations; and a transmission device 1400 for connecting between
the switching devices. . . ." Col. 23, ll. 32-41. We agree with the examiner that the
reference "teach[es] a state machine (1100a, 1100b (see figures 2, 24), operating from
one state to another state (see figures 4A-4G, 9)) . . . so as to control assignment of the
sets of labels (see figures 4A-4G) to soft-labeled keys (1A-1D) (see figure 2) in
response to user input without requiring further information from the switch. . . ."
(Examiner's Answer at 4.) More specifically, Suzuki explains that each state machine
includes "an initial communication waiting state," col. 5, ll. 25-26; "a 'memory call' state,"
id. at ll. 27; and "a speaking state (line connected state). . . ." Id. at ll. 28-29.
Furthermore, Figures 4A-4C of Suzuki show that the labels for the SLKs of each
device are controlled according to the state machines. "In th[e] initial communication
waiting state of FIG. 4A, the input key 1A is [labeled] as an input key for switching the
operation state into a 'memory call' mode, the input key 1C is [labeled] as an input key
for switching the operation state into an 'auxiliary function' mode, and the input key 1D
is [labeled] as an input key for switching the operation state into a 're-dial' mode.
