          Appeal No. 95-4932                                                          
          Application No. 07/990,216                                                  

          components based on their temperature-dependent NO  reduction               
          characteristics would have been obvious or inherent from the                
          teachings of Völker.  In this regard, we note that the active               
          catalyst in Völker may be chosen from a wide variety of                     
          substances (Völker: column 2, lines 28-30); and the individual              
          catalyst components or monoliths of Völker may even include                 
          the same catalytically active substance (Völker: column 3,                  
          13-15).  Under these circumstances, the individual monoliths                
          would differ only so far as the concentration of active                     
          substance differs in each.
