Appeal No. 1997-2984 Page 4
Application No. 08/259,967
(Examiner's Answer at 7.) The appellants argue, "Wilson does not
remotely suggest the step of ‘producing a second clock signal
which is complementary to said first clock signal’, nor the step
of ‘transmitting said data signals and said first and second
clock signals over a bus’." (Appeal Br. at 10.)
Claim 26 specifies in pertinent part the following
limitations: "receiving, on a bus input, at least one data
signal, a first clock signal, a first system potential, and a
second system potential; producing a second clock signal which is
complementary to said first clock signal; transmitting said data
signals and said first and second clock signals over a bus ...."
Accordingly, the limitations require inter alia inputting a data
signal and a clock signal, generating a clock signal
complementary to the inputted clock signal, and transmitting the
inputted clock signal, the complementary clock signal, and the
inputted data signal over a bus.
The examiner fails to show a disclosure of the limitations
in the applied prior art. “A prior art reference anticipates a
claim only if the reference discloses, either expressly or
inherently, every limitation of the claim. See Verdegaal Bros.,
