between base station's transmission of a signal and the base
station’s reception of a corresponding signal from a remote
unit, and compares the phase shift to a threshold.
Furthermore, although Menich’s “receiver hardware [is]
employed to demodulate the transmitted narrowband signal and
determine a signal quality value or signal strength indication
(SSI) of the signal,” col. 5, ll. 20-23, the examiner shows no
evidence to support his allegation that “determining a quality
value . . . reads on [determining a] phase shift. . . .”
(Final Rejection at 3.)
Because there is no showing that Tarallo or Menich
determines a phase shift by measuring a time between base
station's transmission of a signal and the base station’s
reception of a corresponding signal from a remote unit and
compares the determined phase shift to a threshold, we are not
persuaded that the teachings from the applied prior art would
have suggested the limitations of "measuring a time between a
base station's transmitted signal and a corresponding received
signal transmitted from a remote unit to produce a measured
phase shift; comparing the measured phase shift to a threshold
