          Application No. 08/405,912                                                  


          Inoue et al. (Inoue)     4,504,679           Mar. 12, 1985                  
          Zardi                    4,613,696           Sep. 23, 1986                  
          Pagani                     0,479,103              Apr. 08,                  
          1992                                                                        
          (European Patent)                                                           



               Claims 1-8 stand rejected under 35 U.S.C.  103 as being               
          unpatentable over Pagani in view of Inoue and Zardi.                        
                                       OPINION                                        
               We have carefully considered all of the arguments                      
          advanced by appellants and the examiner and agree with                      
          appellants that the aforementioned rejection is not well                    
          founded.  Accordingly, we reverse this rejection.                           
               Pagani discloses an industrial process for producing urea              
          from carbon dioxide and ammonia wherein a so called high yield              
          reactor is added to a lower yield reactor and a recovery                    
          system (page 3, lines 3-12).  As urged by appellants (brief,                
          pages 4-7 and reply brief), the examiner has not convincingly               
          explained how Pagani and the other applied references teach or              
          would have suggested several of the process features required               
          by the claims on appeal herein including the use of a second                
          recovery section (in addition to a first recovery section                   
          associated with a first reaction space) for separating urea,
