          Appeal No. 96-2810                                                          
          Application 08/017,086                                                      
          unpatentability of appellants’ product by process claims under              
          section 102 over the products produced by Norris’s process.                 
               Appellants have two responses to the examiner’s findings.              
          First, appellants argue, “Norris does not anticipate                        
          appellants’ invention under 35 USC 102(e) because Norris does               
          not disclose appellants’ thickener of a hydrophobically                     
          modified hydroxyethyl- cellulose” (Amended Brief For                        
          Appellants, p. 6).  This argument does not respond to what                  
          appears to be a reasonable finding by the examiner that the                 
          thickeners of appellants’ and Norris’s glazed sanitary ceramic              
          articles are not apparent once the glaze has been fired                     
          (Examiner's Answer, p. 5).                                                  
               Second, appellants argue (Amended Brief For Appellants,                
          p. 6):                                                                      
               Moreover, Examples 1 and 2 on page 6 of the application                
               clearly demonstrates that the resulting glaze articles                 
               using appellants’ novel formulation gave superior                      
          unexpected                                                                  
               results over the prior art glaze.  Norris uses xanthan                 
          gum                                                                         
               as the thickener which is what appellants use as the                   
          prior                                                                       
               art control of these experiments.  Appellants invention                
               [sic, Appellants’] provided a faster drying time and                   
          thicker glaze coating which displayed a lower tendency to                   
          run or sag     as well as containing fewer foam bubbles (see                
          lines 8 to 11       of page 6).  Similar results were also                  
          noted in Example 2.      Therefore, Norris clearly does not                 
          anticipate appellants’ invention.                                           
                                       - 11 -
