                Appeal 2007-2337                                                                                 
                Application 10/437,919                                                                           
                particular application.  In re Moore, 439 F.2d 1232, 1235, 169 USPQ 236,                         
                238 (CCPA 1971).                                                                                 
                       After consideration of the present record, we determine that a person                     
                of ordinary skill in the art would have realized, just as asserted by the                        
                Appellant, that the “parts by weight” values recited in the claims are based                     
                on the two polyols in the prepolymer.  Thus, we determine that the claims                        
                reasonably apprise those of ordinary skill in the art of their scope.                            
                Accordingly, we reverse the Examiner’s § 112, second paragraph, rejection                        
                of claims 11-15 and 17-24 as indefinite.                                                         
                The rejected claims under 35 U.S.C. § 103.                                                       
                       Claims 11-15 and 17-24 stand rejected under 35 U.S.C. § 103(a) as                         
                unpatentable over Graefe, Heidingsfeld, or Pudleiner.                                            
                       Appellant does not argue that the applied prior art fails to establish a                  
                prima facie case of obviousness.1  Instead, it is the Appellant’s position that                  
                “[t]he present invention claims the unexpected enhanced properties found in                      
                polyurethane elastomers which incorporate certain glycol phthalic                                
                anhydride-based polyester polyols” (Br. 13).  The Appellant further contends                     
                “[w]hen these polyols are incorporated into the claimed parts per weight                         
                mixtures, the resulting polyurethane elastomers have the following                               
                unexpected, enhanced properties:  reduced thermoplasticity, significantly                        
                increased tear strength when measured both at ambient temperature and at                         
                elevated temperature (70°C), significantly higher flex fatigue resistance, and                   
                higher tensile strength and percent elongation at the same hardness.”  (Br.                      
                13).                                                                                             
                                                                                                                
                1 Appellant does not provide additional details to support the conclusory                        
                statement appearing at the top of the page 13 of the Brief.                                      
                                                       4
