Interference No. 103,891
user any time the strip is used whether the analyte is present or
not. Thus, the invention comprises a test strip with a negative
control, a test zone where the analyte of interest is tested for,
and a positive control. The count corresponds exactly to the
Moorman patent claim 1 and reads as follows:
Count 1
An apparatus for determining an analyte of interest in
a liquid sample comprising an absorptive material and having a
plurality of zones in the direction of fluid flow, wherein:
(i) a first negative control zone of said absorptive
material contains an immobilized reactant which does not bind to
said analyte of interest;
(ii) a second analytical zone of said absorptive
material contains an immobilized reactant which specifically
binds to said analyte of interest; and
(iii) a third positive control zone of said absorptive
material contains both (a) an immobilized reactant which specifi-
cally binds to said analyte of interest, and (b) a portion of the
analyte of interest in solubilizible form, wherein said portion
of the analyte is solubilized when contacted with the liquid
sample and reacts with the immobilized reactant of said third
zone.
The claims of the parties that correspond to the count are:
Flanders: Claims 1-13
Moorman: Claims 1-30
The specific embodiment disclosed by both parties is a
test strip for testing for Streptococcus pyogenes. MX-1, ¶ 2.4
