receive transmit signals from polarization control module 81 and
transmit signals to the antenna (col. 16, lines 53-55; col. 17,
lines 1-3; figure 10), 2) the duplexers receive signals from the
antenna and output receive signals to polarization control
module 83 (col. 17, lines 3-6), and 3) the four ports of the pair
of duplexers can be combined to provide desired pairs of transmit
and receive signals (col. 17, lines 6-8). Runyon discloses that
his polarization control modules 81 and 83 are implemented by
hybrid couplers (col. 17, lines 8-12), but Runyon does not say
that about the duplexers.
The examiner argues that Runyon discloses in figure 11 that
polarization control module 81 has a first output connected to a
first input of “the first polarization coupler” and a second
output connected to a first input of polarization coupler 83
(answer, page 4). As shown in Runyon’s figure 11, however, the
two outputs of polarization control module 81 are connected to
duplexers 80 and 82. Neither output is connected to a “first
polarization coupler” or to polarization control module 83.
The examiner argues that Runyon’s figure 12 discloses a
hybrid coupler connected to the antenna (answer, page 6), but the
examiner does not explain how this disclosure, in combination
with the other disclosures in Runyon, is a disclosure of the
