          Appeal No. 1997-2112                                                        
          Application No. 08/398,831                                                  


               The examiner also appears to raise the spectre of                      
          “provisional double patenting” with respect to “recently                    
          allowed 08/403,332"  on page 11 of the Answer.  However: (1)2                                                        
          no formal rejection has been entered; (2) no basis for the                  
          “provisional double patenting” (e.g., statutory or non-                     
          statutory) rejection is set forth (in fact, although appearing              
          under a “double patenting” heading, it is not entirely clear                
          that it is double patenting which is to “be used to reject the              
          instant application,” but such is presumed in view of                       
          commentary on page 10 of the Answer); (3) no claim-to-claim                 
          comparison of the respective subject matter is set forth; and               
          (4) a position that the instant claims are unpatentable for                 
          obviousness in view of a disclosure by another in 1991, and                 
          yet conflict with claims in a later-filed application in which              
          all claims have been determined by the examiner to be                       
          patentable, appears to be inconsistent on its face.  For at                 
          least the foregoing reasons, we decline to chase the spectre.               


                                     CONCLUSION                                       

               Application for patent filed on March 13, 1995, now U.S. patent2                                                                     
          5,555,270, with inventors Xiao Sun and Carmie A. Hull.
