            Appeal No. 1997-0330                                                        
            Application 08/493,758                                                      




            conducted, appellants have not established unexpected                       
            results for the claimed electrolyte to overcome the prima                   
            facie case.  We therefore affirm the '103 rejection of                      
            claim 1 over Kirman.                                                        

            Anticipation and Obviousness of Claim 3                                     
                  We reverse the '102 rejection as to claim 3 because                   
            this claim requires that the fluoride complexes of claim                    
            1 be Na SiF  or KBF .  Kirman does not disclose these2  6       4                                                        
            complexes and therefore lacks the requisite identity for                    
            anticipating the claim.                                                     
                  There is also no prima facie case of obviousness                      
            under '103 because there is no suggestion in Kirman, and                    
            no other cited art, that would guide one of ordinary                        
            skill to choose these types of complex salts.  We agree                     
            with appellants (brief, p.11, first paragraph) that                         
            Kirman teaches acids as fluoride ion sources and not                        
            salts and does not suggest employing one over the other.                    
            While this argument does not bear on claim 1 where both                     
            acids and salts are covered, claim 3 is specifically                        
            directed to salts.  Examiner bears the burden of showing                    

                          10
