          Appeal No. 1998-1273                                                        
          Application No. 08/624,148                                                  


          required by claim 1, part (c).  The examiner has cited                      
          Dandekar as suggesting temperature control or isothermal beds               
          (Answer, page 3, citing col. 7, ll. 35-45).  However, this                  
          disclosure in Dandekar relates only to attempts to “minimize                
          the temperature increase” in the reactor beds and does not                  
          disclose or suggest isothermal operation (see col. 7, ll. 37-               
          38).                                                                        
               The examiner cites col. 13, l. 30-col. 14, l. 40 of                    
          Keefer (Figure 8) to show the embodiment of Keefer directed to              
          the water gas shift reaction (Answer, page 4).  However, claim              
          1, part (c), step (1) calls for reaction conditions sufficient              
          to convert carbon dioxide and hydrogen to carbon monoxide and               
          water, i.e., the reverse water gas shift (see the                           
          specification, page 1, ll. 11-16, and page 8, ll. 1-10).  The               
          examiner has not explained why one of ordinary skill in the                 
          art would have modified the reaction conditions of Keefer to                
          attain the reaction conditions required by claim 1 on appeal.               
          The examiner has also not explained by convincing evidence or               
          reasoning why the prior art discloses or suggests the                       
          “predetermined time sequences” as required by claim 1 on                    
          appeal.  Furthermore, the examiner has merely stated that                   
                                          9
