          Appeal No. 1996-0684                                                        
          Application No. 08/116,550                                                  


          which is the only other claim remaining in the application,                 
          stands allowed.                                                             
               Claim 1 is representative:                                             


               1.  A process for fluorinating a halogenated hydrocarbon               
          consisting essentially of reacting a halogenated hydrocarbon                
          with hydrogen fluoride in the presence of a fluorination                    
          catalyst which comprises a partially fluorinated chromium                   
          oxide containing from 0.01-10% by mole, based on the amount of              
          chromium oxide, of at least one metal selected from the group               
          consisting of ruthenium and platinum.                                       
               The references relied on by the examiner are:                          
          Manzer                      5,051,537               Sep. 24, 1991           
          Ohsaka                      2,030,981               Apr. 16, 1980           
          (British patent application)                                                
               The issue presented for review is whether the examiner                 
          erred in rejecting claims 1 through 3, 5 through 8, and 10                  
          under 35 U.S.C. § 103 as unpatentable over the combined                     
          disclosures of Manzer and Ohsaka.                                           


                                     DISCUSSION                                       
               In rejecting appellants' claims, the examiner proposes                 
          combining the ruthenium catalyst of Manzer with the partially               
          fluorinated chromium oxide catalyst of Ohsaka to form "a mixed              
          catalyst" containing both ruthenium and partially fluorinated               
                                         -2-
