dry chemical analysis techniques as alternative to solution chemical analysis techniques.
(Answer, p. 4). Przybylowicz describes diagnostic quantitative chemical analysis of
biological liquids including body fluids such as blood, plasma and urine. (Col. 1). The
diagnostic element includes a spreading layer and a reagent layer. The particular interactive
materials that may be distributed within a reagent layer will depend on the analysis of
choice. Przybylowicz also discloses that the reagent could also be placed in the spreading
layer for direct analysis in the absence of a reagent layer. (Col. 9). Examples of the
diagnostic elements include pH test strips and similar indicators wherein the paper responds
to contact with test liquid and either generates color or changes color.
The claimed invention is directed to a porous partition that comprises a porous
material having an aperture and having incorporated and dried therein at least one agent
capable of initiating the blood coagulation. The claimed partition member is similar to the
separating member of von der Goltz. The separating member of von der Goltz is not
described as having incorporated therein at least one dried agent capable of initiating the
blood coagulation. It appears the Examiner has over generalized Przybylowicz’s description
of dry chemical analysis versus solution chemical analysis. The Examiner has not
adequately explained or identified evidence that a person of ordinary skill in the art would
have reasonably expected that the method of analysis described by Przybylowicz would
