          Appeal No. 95-0192                                                          
          Application No. 07/914,228                                                  


               Appellants argue that the prior art references relied on               
          by the examiner are not relevant to each other and to the                   
          claimed subject matter.  This argument, however, is not                     
          convincing.  From our perspective, these prior art references               
          are relevant inasmuch as they are all directed to either the                
          same area of art as the claimed subject matter, or the problem              
          to be solved in the art.  In re Clay, 966 F.2d 656, 659, 23                 
          USPQ2d 1058, 1060-1 (Fed. Cir. 1992); In re Wood, 599 F.2d                  
          1032, 1036, 202 USPQ 171, 174 (CCPA 1979).  As is apparent                  
          from the examiner’s discussion of the prior art in the Answer               
          and appellants’ own description of                                          
          the prior art in the Brief and the Reply Brief, the prior art               
          references in question, like the claimed subject matter,                    
          discuss ingredients useful for forming polyurethane products,               
          i.e., the same area of art as the claimed subject matter.                   
          Moreover,                                                                   
          they all discuss solving problems associated with improving                 
          polyurethane products or improving processes for making                     
          polyurethane products, i.e., the problem to be solved in the                
          art.                                                                        


                                          8
