Ex parte MORADI-ARAGHI - Page 4

          Appeal No. 94-3134                                                          
          Application 07/848,884                                                      

          hexa-methylenetetramine in light of the teaching in Moradi-                 
          Araghi of using either an aldehyde or an aldehyde-generating                
          compound in a gel-forming composition.  That is, an artisan                 
          with ordinary skill would have found in this teaching of                    
          Moradi-Araghi motivation for, and a reasonable expectation of               
          success in, using hexamethylenetetramine as an aldehyde-                    
          generating compound in place of the aldehyde of Mumallah’s                  
          composition.  In re O’Farrell, 853 F.2d 894, 904, 7 USPQ2d                  
          1673, 1681 (Fed. Cir. 1988).  The composition and method                    
          resulting from the substitution in question would fully                     
          correspond the composition and method defined by appealed                   
          independent claims 1 and 25 respectively.                                   
               The appellant seems to believe that it would not have                  
          been obvious to combine the applied references in the above                 
          discussed manner because “Moradi-Araghi specifically discloses              
          that an                                                                     
          aldehyde-generating compound must be used in a composition                  
          which contains a furan derivative in order to be useful”                    
          (Brief, page 4).  We do not agree.  In the first place, we                  
          find no explicit teaching in this reference, and the appellant              
          points to none, that an aldehyde-generating compound such as
