                  Appeal No. 2003-0366                                                                                                                    
                  Application 09/349,759                                                                                                                  

                  93, 16 USPQ2d 1897, 1900-01 (Fed. Cir. 1990)(in banc); In re Payne, 606 F.2d 303, 315-17,                                               
                  203 USPQ 245, 254-56 (CCPA 1979).                                                                                                       
                           Accordingly, since a prima facie case of obviousness has been established over the                                             
                  combined teachings of Beck and the Cattanach references by the examiner, we have again                                                  
                  evaluated all of the evidence of obviousness and nonobviousness based on the record as a whole,                                         
                  giving due consideration to the weight of appellants’ arguments and the evidence in the                                                 
                  specification Examples as relied on in the brief.  See generally, In re Johnson, 747 F.2d 1456,                                         
                  1460, 223 USPQ 1260, 1263 (Fed. Cir. 1984); In re Piasecki, 745 F.2d 1468, 1472, 223 USPQ                                               
                  785, 788 (Fed. Cir. 1984); In re Rinehart, 531 F.2d 1048, 1052, 189 USPQ 143, 147 (CCPA                                                 
                  1976).                                                                                                                                  
                           We have carefully considered all of appellants’ arguments and the evidence presented in                                        
                  the specification as relied on by appellants in the brief.  In view of the substantial evidence we                                      
                  find in Beck and the Cattanach references incorporated by Beck, we cannot agree with                                                    
                  appellants’ contention that the examiner has failed to provide a factual foundation for finding a                                       
                  prima facie case of obviousness.  Because appellants have not submitted argument with respect                                           
                  to the evidence in the applied references, we now consider the objective evidence of                                                    
                  nonobviousness in the specification on which appellants rely in the brief.  See Dillon, 919 F.2d at                                     
                  692-93, 16 USPQ2d at 1901; Payne, 606 F.2d at 315, 203 USPQ at 256.                                                                     
                           Appellants rely on the comparisons provided in specification Examples I and II and the                                         
                  results thereof reported in specification Table I.  The comparisons involve an untreated ZSM-5                                          
                  catalyst, designated “A,” the silylated modification of that catalyst, designated “B,” and the steam                                    
                  treated modification of the silylated catalyst representing claim 36, designated “C.”  Appellants                                       
                  state that the claimed zeolite catalyst “C” exhibited “higher yields of aromatics . . . along with a                                    
                  lower rate of coking” than the other zeolite catalysts (brief, page 5).  Appellants state in the                                        
                  specification that silylated catalysts B and C “exhibited less coking than control Catalyst A which                                     
                  had not been treated,” and that silylated catalysts B and C had higher yields of aromatics than                                         
                  untreated catalyst A, with catalyst C which was steam treated achieving “[a] additional increase”                                       
                  in aromatics compared to catalyst B (pages 11-15).  We note that there appears to be little                                             
                  different between the silylated catalysts B and C with respect to the “Composition of Liquid                                            


                                                                          - 5 -
