          Appeal No. 96-1188                                                          
          Application No. 08/240,800                                                  


          process of Canada '378 would be modified in accordance with                 
          the teachings of Talonen and Strong such that appellants'                   
          claimed process would result.  It appears to us that the                    
          examiner has found that various sulfur dioxide scrubbing                    
          processes in the prior art which utilize aqueous sulfide                    
          solutions generate hydrogen sulfide gas and bisulfite and,                  
          therefore, concludes that one of ordinary skill in the art                  
          would be able to somehow modify all the prior art processes to              
          arrive at the claimed process.  However, it is well settled                 
          that the prior art must provide some teaching or suggestion of              
          the claimed process or some motivation why one of ordinary                  
          skill in the art would perform the claimed steps.  Inasmuch as              
          the examiner has not established on this record the requisite               
          teaching, suggestion or motivation, we must conclude that the               
          examiner has not established a prima facie case of obviousness              
          for the claimed subject matter.                                             
               In conclusion, based on the foregoing, we are constrained              
          to reverse the examiner's rejections.                                       
                                      REVERSED                                        



                         EDWARD C. KIMLIN              )                              
                                         -6-
