Application No. 09/638,214
the current detecting circuit is a conventional technique
well known to one skilled in the art [and]...
the constant-current driving circuit and the voltage
detecting circuit are conventional techniques well known
to one skilled in the art...
Yuyama also shows in Figures 16 and 17 that deterioration of
luminance of the LED is a function of time.
Thus, upon return of this application, the examiner is advised
to determine:
1) Whether the combined teachings of Yuyama and the admitted
prior art discussed above would have rendered the subject
matter defined by claims 16 through 18, 22 through 24 through
26, 30 through 33, 38 and 39 obvious to one of ordinary skill
in the art; and
2) Whether the combined teachings of Yuyama, the admitted prior
art, Nakamura and Asai would have rendered the subject matter
defined by claims 19 through 21, 27 through 29, 34, 36 and 37
obvious to one of ordinary skill in the art.
If the examiner determines that the prior art teachings above would
have rendered the subject matter defined by any of the claims on
appeal obvious, the examiner must reopen the prosecution of this
application.
