         Appeal No. 2002-0148                                                       
         Application No. 09/104,675                                                 
              Other than these conclusory statements, the appellants have           
         not favored us with any explanation in the Briefs or direct                
         citation of evidence in the record as to why their selected                
         comparative example is reflective of the teachings of Bohan or             
         represents a comparison with the closest prior art.                        
              Whether evidence shows unexpected results is a question of            
         fact and the party asserting unexpected results has the burden of          
         proving that the results are unexpected.  In re Geisler, 116 F.3d          
         1465, 1469-70, 43 USPQ2d 1362, 1364-5 (Fed. Cir. 1997).                    
              We have reviewed pages 49-99 of the instant specification in          
         hope of discerning that the comparative examples 002 and 102 are           
         closer than Bohan’s Sample 2, with the most preferred coupler              
         range.  We are unable to discern where the appellants derive               
         support for their contention that the level of DIR components in           
         each layer of their comparative examples are somehow more                  
         representative than Bohan’s preferred range.                               
              Of note, the appellants have directed no specific argument            
         towards this point or pointed to any specific locations in the             
         record where it may be found.  Accordingly, the appellants have            
         failed to carry their burden.                                              
              In their Reply Brief, the appellants further assert that              
         Example 2 of Bohan “clearly states that the masking couplers are           
         omitted from the sample”  (Reply Brief, page 2, lines 2-3) and             

                                         12
