Ruhenstroth-Bauer et al, Brown et al and Deutsch et al.” (Br. at 14 and App.
4).
32. As to Deutsch, the Examiner stated, “[i]t would be obvious that any
known reaction within reasons [sic] could be incorporated in the modified
method and apparatus of either Morison and Bauer, as see, for example the

follows:
Method for the quantitative analysis of an analyte in a carrier liquid,
characterized by the steps of:
Providing a fluid-permeable solid medium defining a flow path
and having predetermined number of successive, spaced reaction
zones in the path of flow, said reaction zones having immobilized
therein a reactant reactive with the analyte or any analyte derivative or
both to result in the formation of a predetermined product;
Flowing said fluid along the flow path and sequentially through
the spaced reaction zones; and
Detecting the presence of analyte, analyte derivative, reactant or
predetermined product in the reaction zones;
The amount of analyte in the fluid being a function of the
number of zones in which such detection occurs.
(Br. at 14 and App. 4 ).
