allegation is contrary to the actual teachings of Burton. In
particular, Burton teaches that, in the most typical
situation, the interior boiler 10 can be accessed only in the
area of the flame 15 and at an area above the flame, where the
temperatures at full load are typically within the range of
about 2,050EF and above (column 5, lines 29-37).
Additionally, Burton teaches that in the exemplary case of
aqueous urea solution, pollutant reduction can occur at
temperatures above about 1,300EF with enhancers and above
about 1,550EF without enhancers (column 5, lines 20-24). No
other evidence has been presented by the examiner to establish
that additives other than urea would not be effective at the
boiler temperatures disclosed in Burton. Given the
disclosures in Burton, we see no reason why one of ordinary
skill in the art would have been motivated to monitor the
temperature to activate or deactivate supply conduit 24 in the
manner as suggested by the examiner. That is, the examiner
has not established the requisite factual basis upon which to
conclude that a person of ordinary skill in the art would have
found any incentive or suggestion in the prior art to monitor
