         Appeal No. 1999-2507                                                        
         Application No. 08/967,367                                                  



         1990)(en banc).  Here, the appellants have not pointed to any               
         objective evidence (e.g., comparative experimental data)                    
         establishing otherwise.                                                     
               The appellants urge that "in the case of graft product A,             
         the particulate rubber must be a silicone rather than a                     
         polymerized unsaturated compound ."  On this point, we agree with           
         the examiner's analysis.  (Examiner's answer, page 10.)                     
               For these reasons and those set forth in the answer, we               
         uphold this ground of rejection as well.                                    
                                      Summary                                        
               In summary, we affirm the examiner's rejections under 35              
         U.S.C. § 103 of appealed claims 9 through 14 and 16 through 23 as           
         unpatentable over: (1) Brekner and/or Yamamoto in view of                   
         Laughner; and (2) Eichenauer.                                               
               The decision of the examiner to reject appealed claims 9              
         through 14 and 16 through 23 is affirmed.                                   
               No time period for taking any subsequent action in                    
         connection with this appeal may be extended under 37 CFR                    
         § 1.136(a).                                                                 
                                      AFFIRMED
