representing blood pressure or pulmonary artery wedge pressure
in response to the control signals.
The Examiner responds that "Appellants have not invented
cardiac output measurements or wedge procedures or the display
thereof, per se" (EA20). We agree. However, Appellants claim
more than just the display of certain measurements.
The Examiner states that Policastro's teaching of time
division multiplexing of signals "clearly suggests the
transmission and reception of at least two different control
data signals (i.e., a first and second signal)" (EA21). We
disagree. As we understand Policastro, the time division
