          Appeal No. 2001-2204                                                        
          Application No. 09/155,413                                                  

          on lack of enablement.  See In re Strahilevitz, 668 F.2d 1229,              
          1232, 212 USPQ 561, 563 (CCPA 1982) and See In re Marzocchi,                
          439 F.2d 220, 224, 169 USPQ 367, 370 (CCPA 1971).  Once this is             
          done, the burden shifts to an appellant to rebut this conclusion            
          by presenting evidence to prove that the disclosure is enabling.            
          See In re Doyle, 482 F.2d 1385, 1392, 179 USPQ 227, 232 (CCPA               
          1973), cert. denied, 416 U.S. 935 (1974) and In re Eynde,                   
          480 F.2d 1364, 1370, 178 USPQ 470, 474 (CCPA 1973).                         

               We fully comprehend the examiner's viewpoint of the                    
          enablement issue as clearly articulated in the answer (pages 2              
          through 8).  Akin to the examiner's perception, a reading of                
          appellant's underlying specification reveals to us a disclosure             
          that for the most part leaves it to those practicing the art the            
          task of bringing into being the apparatus for practicing the                
          invention.  The issue, of course, is whether appellant's                    
          aforementioned underlying teaching would have enabled one skilled           
          in the art to make and use the invention without undue                      
          experimentation.  Taking into account the totality of the                   
          particular evidence and information before us, it is our opinion            
          that the examiner has not produced reasons that substantiate a              
          rejection based on lack of enablement.  In other words, while               
                                          4
