view of Kageyama and Devine. In support of the rejection, the
examiner states:
. . . Mick shows a method and apparatus for
non-invasive measurement of intracranial
changes in pressure in which a pre-
determined signal (Col. 6, Lns. 9-11) of a
particular frequency, the fundamental
resonant frequency is known for the skull
(Col. 5, Lns. 64-66), is applied to the
skull, an output is detected at another
location on the skull and the variations
between the input signal and the resultant
signal are measured. Mick however, does
not show the application of an ultrasonic
oscillatory excitation applied to the head
or the generation of a standing wave.
[Examiner’s answer at page 3-4].
The examiner has cited Kageyama for showing the utilization of
ultrasonic waves from a pulser for excitation in an analogous
art for the purpose of measuring their echo to determine
intracranial pressure. The examiner concludes:
It would have been obvious for a person of
ordinary skill in the art at the time this
invention was made to incorporate the use
of ultrasonic waves because they are
commonly used wave frequency for medical
applications.
[Examiner’s answer at page 4].
Appellant argues that Mick does not disclose the application
of a single frequency to the skull bone, i.e., Mick does not
