          Appeal No. 96-0814                                                          
          Application 08/066,331                                                      


               Thus, the specification is non-enabling. [answer, page                 
               5]                                                                     
               The dispositive issue with regard to the enablement                    
          requirement found in the first paragraph of 35 U.S.C.  112 is              
          whether the appellants’ disclosure, considering the level of                
          ordinary skill in the art as of the date of the appellants’                 
          application, would have enabled a person of such skill to make              
          and use the claimed invention without undue experimentation.  In            
          re Strahilevitz, 668 F.2d 1229, 1232, 212 USPQ 561, 563-64 (CCPA            
          1982).  The amount of experimentation required, in addition to              
          not being undue, must not require ingenuity beyond that expected            
          of one of ordinary skill in the art.  In re Angstadt, 537 F.2d              
          498, 504, 190 USPQ 214, 218 (CCPA 1976).  The examiner has the              
          initial burden of producing reasons that substantiate a rejection           
          based on a lack of enablement.  In re Strahilevitz, 668 F.2d at             
          1232, 212 USPQ at 563 (CCPA 1982) and In re Marzocchi, 439 F.2d             
          220, 224, 169 USPQ 367, 370 (CCPA 1971).  Once this is done, the            
          burden shifts to the appellants to rebut this conclusion by                 
          presenting evidence to prove that the disclosure is enabling.  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).                                        

                                          4
