                                     BACKGROUND                                       
               The appellants' invention relates to a microplate                      
          assembly for use in analyzing samples captured on a filter                  
          medium.  An understanding of the invention can be derived from              
          a reading of exemplary claim 1, which appears in the appendix               
          to the appellants' brief.
