of an associated antenna is less or more than a desired
reception range. To the contrary, the reference’s variable
attenuators are adjusted “to achieve a linear input-output
characteristic over a wide range of input signal levels.”
Col. 2, ll. 13-14.
Because Sasaki adjusts its attenuators to achieve a
linear input-output characteristic, we are not persuaded that
teachings from the prior art would have suggested the
limitations of "adjusting a reception range of the antenna by
changing attenuation of signals applied to the receiver by the
steps including; if the reception range is less than a desired
reception range, decreasing attenuation; and if the reception
range exceeds the desired reception range, increasing
attenuation ...." Therefore, we reverse the rejection of
claims 1 and 4 as being obvious over Sasaki. We proceed to
the second group of claims.
Claims 2, 3, 5, and 6
The appellants argue, “Appellant repeats the arguments
for claim 1 regarding attenuation and overlap. Further
