Appeal No. 2003-2072
Application No. 09/735,439
277 F.3d 1338, 1344, 61 USPQ2d 1430, 1434 (Fed. Cir. 2002). With
these principles in mind, we commence review of the pertinent
evidence and arguments of Appellant and Examiner.
Appellant argues that the Examiner has not pointed to any
teachings in Miyata or Hamano to configure a common-based
transistor to act as a switch. See page 3 of the brief and reply
brief.
The Examiner has shown that Miyata's Figure 1 shows a
transfer switch having a test signal input and first and second
ports, the transfer switch comprising a first routing switch
having a routing switch input for receiving said test signal
input and said first and second outputs, each output being
connected to the routing switch by a first switching element and
each output being connected to ground by a second switching
element as recited in Appellant's claim 1. See page 3 of the
Examiner's answer. The Examiner agrees that Miyata does not
teach first and second port termination switches connected to
said first and second outputs, respectively, of said first
routing switch, each termination switch comprising a common-base
transistor as recited in Appellant's claim 1. However, the
Examiner points to Hamano's Figure 10 which shows a low-pass
filter for filtering very high frequency. The Examiner points
