          Appeal No. 1996-0740                                                        
          Application No. 08/107,146                                                  


          evidence of unexpected results.  Accordingly, we will not                   
          sustain the examiner's rejection.                                           
               It does not appear that appellants dispute the examiner's              
          determination that it would have been prima facie obvious for               
          one of ordinary skill in the art to replace the hydroxy on the              
          pyrazole moiety of Ciba with the claimed amino substituent in               
          view of the teachings of the secondary references that the                  
          hydroxy and amino substituents are interchangeable on a                     
          pyrazole moiety of reactive dyes.  Rather, it is appellants'                
          contention that the Smith Declaration of October 16, 1992, the              
          Brierley Declaration of October 21, 1992, the Ebenezer                      
          Declaration of September 23, 1993, the Butterworth Declaration              
          of September 22, 1993 and the Ebenezer Declaration of August                
          21, 1995 establish unexpected results for the claimed dyes and,             
          therefore, rebut the prima facie case of obviousness.  In                   
          particular, the Brierley Declaration demonstrates that a dye of             
          the present invention has far better build-up on cotton over a              
          variety of concentrations and temperatures in comparison to a               
          dye that is identical to the claimed dye with the exception of              
          the presence of a hydroxy substituent instead of an amino                   
          substituent on the pyrazole moiety.  Also, the Butterworth                  

                                         -4-
