          Appeal No. 95-2718                                                          
          Application 07/914,852                                                      

          oxide doped with tin (ITO) and doped tin oxide coatings, with               
          doped tin oxide being widely used in displays and as solar                  
          coatings.  Tin oxide coatings are also widely used in                       
          electrochromic devices.”  Moreover, we find that the claim                  
          language “a conductive tin oxide film” encompasses a                        
          conductive coating of indium tin oxide.                                     
               Appellants also maintain that Moser does not recognize                 
          the problem of poor optical quality of tin oxide films, which               
          the claimed method addresses.  However, it is well settled                  
          that the prior art need not disclose the same purpose for a                 
          claimed method in order to establish its obviousness under                  
          35 U.S.C.  103.  In re Dillon, 919 F.2d 688, 693, 16 USPQ2d                
          1897, 1901 (Fed. Cir. 1990), cert. denied, 500 U.S. 409                     
          (1991).  Since it is our view that one of ordinary skill in                 
          the art would have found it obvious to select tin oxide as the              
          conductive surface coating in the Moser method, any haze                    
          contained therein would have been necessarily reduced by the                
          metal oxide coating.  In addition, we note that appellants                  
          base no argument upon objective evidence of nonobviousness.                 
               Page 3 of the Examiner’s Answer indicates that appealed                
          claim 5 is free of the prior art.  Indeed, we find no teaching
