OTHER ISSUES
If prosecution is resumed in this application, the examiner and appellant should
consider the following issues:
(1) Do the recited active benzimidazole compounds in the claims encompass the
weakly cationic benzimidazole compounds described by Miyamoto6, in light of the
disclosure of this application?
The instant specification discloses that the benzimidazole compounds are those
represented by the general formula at page 52, lines 1-5. The formula does not limit the
substituent groups on the benzimidazole structure. Miyamoto describes an ink jet
recording sheet. The sheet comprises a paper support and a coating layer thereon that
comprises oxidized starch (MS 3800, manufactured by Nihon Shokuhin Kako Co., Ltd.)
and a weakly cationic benzimidazole derivative, as a cationic fluorescent brightening
agent. See Examples 1 and 2, at column 6, and column 5, lines 43-44.
6Miyamoto was cited as an “X” reference in the European Search Report that
was filed in the Information Disclosure Statement on Jul. 14, 1997, attached to Paper
No. 24.
