hearing that the appealed claim is limited to a process for
determining the presence or absence of a plurality of
different medicament (antibiotic) residues in a biological
test fluid. See the brief at page 5 and the specification at
page 4, lines 8-10. The microtitration unit is defined
structurally as a container including at least one partition
which subdivides the container into at least two chambers for
accommodating the different test reaction mixtures.
Additionally the partition extends from the container bottom
to a height above the filling levels of the different test
reaction mixtures. After introduction of the different test
reaction mixtures into the chambers, a sufficient amount of
biological test fluid (e.g., an antibiotic residue containing
milk) is added so that it flows over the top edge of the
partition to flood the different test reaction mixtures in the
defined chambers. Finally, the results of the interactions of
the biological test fluid with the different test reaction
mixtures are detected, e.g., by observation of color changes
in the chambers. See the specification at page 3, lines 3-9.
As evidence of obviousness of the claimed method, the
examiner relies upon the combined teachings in the relied upon
