                   Armbruster, 512 F.2d 676, 678, 185 USPQ 152, 153 (CCPA 1975).  If the                                          
                   specification “contains a teaching of the manner and process of making and                                     
                   using the invention in terms which correspond in scope to those used in                                        
                   describing and defining the subject matter sought to be patented[, it] must be                                 
                   taken as in compliance with the enabling requirement of the first paragraph of                                 
                   § 112 unless there is reason to doubt the objective truth of the statements                                    
                   contained therein which must be relied on for enabling support.”  In re Marzocchi,                             
                   439 F.2d 220, 223, 169 USPQ 367, 369 (CCPA 1971), emphasis in original.                                        
                          Further, a conclusion of nonenablement must be supported by evidence or                                 
                   scientific reasoning.  See Armbruster, 512 F.2d at 677, 185 USPQ at 153 (“[T]he                                
                   Patent and Trademark Office must substantiate its rejection for lack of                                        
                   enablement with reasons.” (emphasis in original)).  See also Marzocchi, 439 F.2d                               
                   at 224, 169 USPQ at 370 (“[It] is incumbent upon the Patent Office, whenever a                                 
                   rejection on this basis is made, to explain why it doubts the truth or accuracy of                             
                   any statement in a supporting disclosure and to back up assertions of its own                                  
                   with acceptable evidence or reasoning which is inconsistent with the contested                                 
                   statement.”).                                                                                                  
                          In this case, the examiner has provided no Wands-based analysis to                                      
                   support the conclusion of nonenablement and has pointed to no evidence in the                                  
                   record to support the assertion that the claimed method is likely to be inoperative.                           
                   With regard to the asserted requirement for undue experimentation, we note that
