          Appeal No. 2000-1386                                                       
          Application No. 09/078,477                                                 

               Secondly, appellants improperly attempt to overcome the               
          rejection by attacking the references individually when the                
          rejection is based on a combined teaching.  See In re Young, 403           
          F.2d 754, 757, 159 USPQ 725, 728 (CCPA 1968).  In this case, we            
          conclude that the Examiner has established the requisite motivation        
          to utilize Huttlin’s rotary drum process in Moore’s process of             
          coating granules with a polymer coating3, i.e., “the expectation           
          that the rotary drum would effectively coat the granules of Moore,         
          as it had in Huttlin” (Examiner’s Answer, page 4).                         
               Finally, contrary to appellants’ assertion, Huttlin does, in          
          fact, teach the use of “a plurality of nozzles 42” for application         
          of the coating to the granular material.  Column 4, line 43.               
          Accordingly, we find that the examiner has established a prima             
          facie case of obviousness with respect to claim 16, which                  
          appellants have failed to rebut.                                           
               Claims 17-19                                                          
               Claim 17 depends from claim 16 and includes the further               
          limitation that the first and second coating components are applied        
          by injecting the coating components into the cascading material at         
          the top moving layer.  We find that this limitation fails to               
               3                                                                     
               3See Moore, column 7, lines 4-47, for a discussion of the             
          polymer coating.                                                           
                                         10
