Appeal No. 95-4089
Application 08/090,073
in connection with an earlier PCT application filed by
applicants. The reference is Cook, U.S. Patent 5,008,030
(1991).8
36. We are at a loss to understand why the examiner
did not cite and apply Cook.
37. Cook describes "all-purpose liquid cleaning
compositions for use on hard surfaces" (col. 1, lines 7-8)
which are said to be "effective in removing soap scum ***
[from] hard surfaces being cleaned" (col. 1, lines 9-11). The
compositions are said to be "particularly suitable for
cleaning hard surfaces such as *** glass and ceramic tile"
(col. 3, lines 55-58). 38. According to Cook, his
"compositions exhibit improved efficacy in removing soap scum
and mineral deposits and, therefore, have particular utility
in the cleaning of bathrooms and kitchens" (col. 3, lines 61-
64).
39. Cook, like applicant, seeks to eliminate the use
of phosphoric acid apparently based on environmental concerns
(col. 3, lines 20-22).
As noted earlier, Cook is prior art under 35 U.S.C. § 102(e).8
