          Appeal No. 1998-1667                                                        
          Application No. 08/224,211                                                  

          while claims 4 through 9 are objected to by the examiner as                 
          being dependent upon a rejected base claim, but would be                    
          allowable if rewritten in independent form including all of                 
          the limitations of the base claim and any intervening claims                
          (see the Final Rejection dated Aug. 29, 1996, Paper No. 8,                  
          page 4; and the Brief, pages 1-2).                                          
               According to appellants, the invention is directed to a                
          method of polishing a ferroelectric material using a specified              
          acidic polishing solution and an external polishing member                  
          (Brief, page 2).  A copy of illustrative claim 1 is attached                
          as an Appendix to this decision.                                            
               The examiner has relied upon the following references as               
          evidence of obviousness:                                                    
          Maniar                        5,258,093          Nov. 2, 1993               
          Sandhu et al. (Sandhu)        5,318,927          Jun. 7, 1994               
                         (U.S. filing date of Apr. 29, 1993)                          
               Claims 1-3 stand rejected under 35 U.S.C. § 103(a) as                  
          unpatentable over Sandhu and Maniar (Answer, page 3).  We                   
          reverse this ground of rejection for reasons which follow.                  
          OPINION                                                                     
               The examiner finds that Sandhu discloses a method of                   
          polishing a ferroelectric material by use of an aqueous acidic
