Appeal No. 2000-1519
Application No. 08/674,875
35 U.S.C. 103 as unpatentable over APA in view of Lemson.
Reference is made to the briefs and answer for the
respective positions of appellants and the examiner.
OPINION
It is the examiner’s position that APA discloses the instant
claimed invention but for a transmission system comprising a
level comparator and a gain controller for reducing the gain of
the antenna unit when the received signal exceeds a predetermined
threshold. However, the examiner, referring to Figures 2-4 and
8-12, column 10, lines 10-47, column 17, line 39 to column 18,
line 31, and column 37, lines 43-62, of Lemson, contends that
Lemson teaches remote antenna units wherein each of the remote
units comprises a level comparator and a gain controller for
reducing the gain of the antenna unit when the received signal
exceeds a predetermined threshold.
The examiner then concludes that it would have been obvious
to modify APA by providing the teaching of Lemson in “order to
efficiently maintain an optimum level over a transmission line of
the system” [answer-page 4]. Even so, the examiner indicates
that this modification would include the gain control circuit
