threshold measure is formed from a simple sum of the square
of signal differences. There is no weighting indicated in the
formula in Gerard, and there is certainly no weighting that
weights low-frequency transform signal differences greater
than high-frequency transform signal differences. Thus, the
examiner has improperly interpreted the teachings of Gerard
and has, therefore, failed to establish a prima facie case of
the obviousness of claim 40. Accordingly, we do not sustain
the examiner’s rejection of claim 40.
