sensors for combining the seismic signals to produce at least
one seismic trace.
Based on our assessment of Read and McNatt and claim 30,
it is our opinion that the differences are (1) each seismic
trace being produced with a seismic receiver by combining a
selected group of received seismic signals; and (2) the
combining of each selected group of received seismic signals
to produce each of the seismic traces is controlled by
transmission of control signals from the recording and control
station to a plurality of controlled elements to modify each
selected group to change the received seismic signals in each
selected group or to modify which of the received seismic
signals in each selected group are combined to produce each
seismic trace.
The examiner determined (answer, p. 7) that it would have
been obvious to one skilled in the art to combine the
teachings of Miller with either Read or McNatt. While we
agree with that determination, we fail to see how the
modification of either Read or McNatt based on the cited
