Appeal No. 97-2120
Application No. 08/226,164
Claims 3 through 6, 9, 11 and 12 stand rejected under
35 U.S.C. § 103 as being unpatentable over Martinez.
Reference is made to the brief and the answer for the
respective positions of the appellant and the examiner.
OPINION
We have carefully considered the entire record before us,
and we will reverse the obviousness rejection of claims 3
through 6, 9, 11 and 12.
Martinez discloses a method and apparatus for enhancing
seismic data by removing phase distortion from deconvolved
seismic data records generated via vibrational energy.
According to Martinez (column 1, lines 24 through 27),
deconvolution is a “form of inverse filtering which corrects
for the previous filtering effects of the recording system and
the earth itself.” The land-vibrator seismic system disclosed
by Martinez includes a baseplate 14 (Figure 1) coupled to the
earth to induce seismic waves of varying frequencies into the
earth. A ground force signal 34 is produced by the seismic
system, and appellant acknowledges (Brief, page 5) that “the
ground force signal (34 in FIG. 2 of Martinez) would
inherently include harmonics produced by the vibrator system.”
