          Appeal No. 97-1999                                                          
          Application 07/390,745                                                      
          compound possessing partial agonist properties for the                      
          strychnine insensitive glycine modulatory site of the N-                    
          methyl-D-aspartate receptor complex in an amount effective to               
          alleviate the symptoms of any neuropsycho-pharmacological                   
          disorder.                                                                   
               We recognize that In re Marzocchi, 439 F.2d 220, 224,                  
          169 USPQ 367, 369-370 (CCPA 1971), instructs:                               
               [I]t is incumbent upon the Patent Office, whenever a                   
               rejection . . . [under section 112, first paragraph] 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.                                                             
          Nevertheless, Nadler and Marvizon themselves strongly suggest,              
          and appellants have argued consistent with that suggestion,                 
          that persons having ordinary skill in the art reasonably could              
          not have predicted success in treating                                      
          neuropsychopharmacological disorders with agonists,                         
          antagonists, or partial agonists which are structurally                     
          similar to ones previously found to exhibit moderate success                
          either in in vitro tests or in vivo tests using model animals.              
          See pages 8-9 of Transmittal of Art, filed August 19, 1997,                 
          which we invite the examiner to study.  In an unpredictable                 
          art, Section 112 requires that the scope of the claimed                     
                                       - 17 -
