          Appeal No. 2001-0784                                                        
          Application No. 08/755,844                                                  

          Accordingly, we shall limit our consideration to claim 1, the sole          
          independent claim, which reads as follows:                                  
          1.   A process for the preparation of a ceramic foam support                
          supporting at least one catalytically active component or precursor         
          thereof, which component is active in a form other than an                  
          inorganic oxide, the process comprising impregnation of the ceramic         
          foam containing pores with an impregnating phase comprising the             
          catalytically active component or a precursor thereof and drying,           
          wherein the impregnating phase has a viscosity of from 5 to 80 cps,         
          wherein drying is performed without substantial prior draining of           
          impregnating phase from the ceramic foam, and wherein the                   
          catalytically active component or precursor thereof is present              
          throughout the preparation process in one or more forms other than          
          the inorganic oxide thereof.                                                
               All of the appealed claims stand rejected for obviousness              
          under 35 U.S.C. § 103 based upon the following single prior art             
          reference:                                                                  
          Jacobs et al.  (Jacobs)            5,510,056      Apr. 23, 1996             
                                   (effective filing date: Nov. 29, 1994)             
               We have carefully considered the entire record on appeal in            
          light of the opposing positions taken by the appellants and by the          
          examiner.  Having done so, we agree with the appellants that the            
          examiner has failed to establish a prima facie case of obviousness          
          as to the claims on appeal.                                                 
               Accordingly, we shall reverse the rejection at issue                   
          essentially for the reasons advanced by appellants.  Suffice it to          
          say that we find nothing in Jacobs which would teach or suggest             
          using an impregnation solution having any particular viscosity, let         
                                          2
