Application No. 08/180,767
wavelengths for simultaneous use in a medical procedure, and
“means for controlling populations of multiple lasing energy
level transitions to thereby control relative intensities
among the coaxially transmitted wavelengths, thereby to
providing a means for controlling total intensities of such
transmitted wavelengths.” Each of claims 13, 19 and 29, the
other independent claims on appeal, contains similar
limitations.
The examiner considers that Piper discloses a device as
set forth in claim 1 except for the means for controlling the
relative intensities of the transmitted wavelengths. The
examiner further considers that Kung discloses controlling the
intensity of each of a plurality of coaxially transmitted
laser beams and the ratio thereof. Based on the above, it is
the examiner’s foundation position that it would have been
obvious to one of ordinary skill in the art to include in
Piper a means for controlling the individual intensities of
the metal vapor laser thereof “since this enables the
treatments to be carried out under the most desirable
irradiating conditions, as taught by Kung” (answer, page 3).
