            Appeal No. 2001-2628                                 Page 4             
            Application No.  09/259,888                                             

                 Also, it is well settled that the examiner has the                 
            burden of providing a reasonable explanation, supported by              
            the record as a whole, why the assertions as to the scope of            
            objective enablement set forth in the specification are in              
            doubt, including reasons why the description of the                     
            invention in the specification would not have enabled one of            
            ordinary skill in this art to practice the claimed invention            
            without undue experimentation, in order to establish a prima            
            facie case under the enablement requirement of the first                
            paragraph of § 112.  In re Wright, 999 F.2d 1557, 1561, 27              
            USPQ2d 1510, 1513 (Fed. Cir. 1993); In re Marzocchi, 439                
            F.2d 220, 223-24, 169 USPQ 367, 369-70 (CCPA 1971).                     
                 Here, the examiner does not explain why the description            
            of the invention as set forth in the specification would not            
            have enabled one of ordinary skill in the art to practice               
            the claimed invention without undue experimentation.                    
                 We therefore determine that the examiner has not met               
            the required burden as described above.
