Appeal No. 2002-0834
Application 09/275,386
Here, Bohnen does not need to teach that the disclosed
benzotriazole is useful as a corrosion inhibitor for deoxidizing
aluminum. All that is necessary is what the combined teachings
of Johnson in view of Bohnen would have suggested to those of
ordinary skill in the art. In the instant case, we agree with
the examiner that because Bohnen teaches that the benzotriazole
is a useful stabilizer for hydrogen peroxide, it would have been
obvious to have exchanged the stabilizer in Johnson with the
benzotriazole of Bohnen. We also find that the different etching
rates of Johnson and Bohnen (as alleged by appellants) would not
dissuade the skilled artisan from utilizing the benzotriazole of
Bohnen in the composition of Johnson.
We therefore affirm this rejection.
II. The rejection involving Johnson in view of Bohnen and
further in view of Ishizuka
Claims 4 and 8 are rejected in this rejection.
The examiner relies upon Ishizuka for the teaching of the
use of propylene glycol as a stabilizer for hydrogen peroxide and
the examiner refers to column 7, lines 40-48 of Ishizuka.
(answer, page 6).
Appellants argue that the disclosure found in column 7
beginning at line 40 of Ishizuka does not indicate whether the
propylene glycol is used as a stabilizer for hydrogen peroxide or
as a dissolution accelerator for copper. (brief, page 14, reply
brief, page 4).
In response, on page 9 of the answer, the examiner refers to
a partial sentence from column 7, beginning at line 40 of
Ishisuka. Hence, the examiner does not fully set forth the
