oligoglucoside having a degree of polymerization of 1.60 gives a
cleaning power reflectance of 51 percent.
The examiner argues that “there appears to be no comparative
composition in Table 1 reasonably representative of Wolf et al.,
considered to be the closest prior art of record” (answer,
page 7). In Wolf’s examples a C8-10 fatty alcohol mixture is
reacted with a glucose syrup, and the degree of polymerization is
not reported. The examiner has not explained why the appellants’
comparative C8-10 alkyl oligoglucosides having a degree of
polymerization of 1.38 to 1.59 are not at least as close as the
alkyl glucoside in Wolf’s examples to the appellants’ alkyl
oligoglucoside.
The examiner argues that “the inventive compositions in
instant Tables 1 [sic] cannot be considered commensurate in scope
[with the appellants’ claims], since very specific types of
surfactants are used in very specific amounts, whereas none of
the present claims appear to be so limited” (answer, page 7).
For the following reasons this argument is not convincing.
First, the appellants’ claims are limited to alkyl
oligoglucosides derived from C9-11 oxoalcohols. The appellants’
