Appeal No. 1997-1726
Application No. 08/401,077
Appealed claim 4 is reproduced below:
4. A method for testing and analyzing a biological test
fluid comprising
- introducing into at least two chambers of a
microtitration unit, different test reaction mixtures,
comprising agar-agar nutrient medium, test microorganisms and
a microbial growth indicator, said microtitration unit having
at least one container of transparent material, the container
including an opening for the introduction of test reaction
mixtures and biological test fluid and at least one partition
subdividing the container into said at least two chambers for
accommodating said biological test reaction mixtures, the at
least one partition extending from the inside of the container
bottom and being of lower height than the internal height of
the container and above the filling levels of the different
test reaction mixtures,
- adding a sufficient amount of biological test fluid to
be tested or analyzed whereby the biological test fluid flows
over the top edge of at least one partition whereby the
biological test fluid floods over the at least two chambers
and the biological test fluid makes contact with the different
test reaction mixtures, and
- detecting the results of the interactions of the
biological test fluid with different test reaction mixtures.
As evidence of obviousness, the examiner relies upon the
