Appeal No. 95-4089
Application 08/090,073
(1991), which tells us that certain "prior art compositions2
incorporate phosphate acids and consequently have associated
problems concerning environmental safety" (col. 3, lines 20-
23).
3. Applicant's cleaning compositions "comprise from
4% to 25% by weight of the total composition of maleic acid"
(specification, page 3, third paragraph).
4. Applicant's cleaning compositions also "comprise
a nonionic surfactant system" (page 4, first full paragraph).
Apparently, nonionic surfactant systems are "more desirable"
because anionic and cationic surfactants are said to
"adversely affect the limescale removing capacity of maleic
acid" (specification, page 4, second full paragraph). The
nonionic surfactant comprise from 1% to 15% by weight of the
cleaning composition (id.).
5. There is data described in the specification,
which is apparently based on actual experimentation. The3
data is said to show that (1) a cleaning composition
Cook is prior art under 35 U.S.C. § 102(e).2
Applicant submitted no declaration under 37 CFR § 1.132 to establish that3
experimental work described in the specification was actually conducted. However, the
specification says experimental work was conduced. We decide the appeal on the basis
that the data described in the specification is based on actual experiments.
