                 the claimed alloys as encompassed by the appealed claims.  Cf. In re Spada, 911 F.2d 705, 708-                                       
                 09, 15 USPQ2d 1655, 1657-58 (Fed. Cir. 1990) (“The Board held that the compositions claimed                                          
                 by Spada ‘appear to be identical’ to those described by Smith. While Spada criticizes the usage                                      
                 of the word ‘appear’, we think that it was reasonable for the PTO to infer that the polymerization                                   
                 by both Smith and Spada of identical monomers, employing the same or similar polymerization                                          
                 techniques, would produce polymers having the identical composition.”).                                                              
                          Accordingly, since the examiner has failed to establish a prima facie case of obviousness                                   
                 under § 103(a), we reverse the ground of rejection.                                                                                  
                          The examiner’s decision is reversed.
