          Appeal No. 95-0996                                                          
          Application 07/943,025                                                      

          ‘410, for the reasons stated above.  A lesser burden of proof               
          is needed to make out a prima facie case of obviousness in                  
          product-by-process claims than in conventional product claims.              
          See In re Fessman, 489 F.2d 742, 744, 180 USPQ 324, 326 (CCPA               
          1974).  Once it is shown that the claimed product reasonably                
          appears to be the same or substantially similar to the product              
          of the prior art, the burden shifts to appellants to                        
          establish, through objective evidence, an unobvious difference              
          between the claimed and prior art product.  See In re Best,                 
          562 F.2d 1252, 1255-56, 195 USPQ 430, 433-34 (CCPA 1977); Ex                
          parte Phillips, 28 USPQ2d 1302, 1303 (Bd. Pat. App. & Int.                  
          1993).                                                                      
               The Kersting Declaration dated Dec. 6, 1993, has been                  
          considered.  However, in view of the new ground of rejection,               
          this comparison is not with the closest prior art.  See In re               
          Baxter Travenol Labs., 952 F.2d 388, 392, 21 USPQ2d 1281, 1285              
          (Fed. Cir. 1991).  Accordingly, we find that appellants have                
          not presented objective evidence, on this record, which would               
          serve to rebut the prima facie case of obviousness established              
          by Tachikawa II or EP ‘410.                                                 
               C.  Summary                                                            



                                         10
