          Appeal No. 1999-0771                                                        
          Application No. 08/640,144                                                  

          ester units in an amount equal to (1-x), wherein x is a value               
          between 0.1 and 1.0.1                                                       
               What is clearly missing from the rejection based on 35 U.S.C.          
          § 102(b) is any explanation of why Green ('052) "clearly                    
          anticipates" the claimed antihalation composition comprising a              
          resin binder composed of anthracene units and carboxy and/or alkyl          
          ester units.  See In re Piasecki, 745 F.2d 1468, 1472, 223 USPQ             
          785, 788 (Fed. Cir. 1984) (the examiner bears the initial burden of         
          presenting a prima facie case of patentability).  For this reason,          
          the rejection of claim 38 under 35 U.S.C. § 102(b) as being clearly         
          anticipated by Green ('052) is reversed.                                    
               B.   Claims 39 through 45                                              
               Claims 39 through 45 depend from claim 38.  Therefore, for the         
          reasons set forth above reversing the rejection of claim 38, the            
          following rejections are also reversed: (1) the rejection of claims         
          39 and 45 under 35 U.S.C. § 102(b) as being clearly anticipated by          
          Green ('052), (2) the rejection of claims 40 through 42 under 35            
          U.S.C. § 103 as being unpatentable over Green ('052) in view of             
          Green ('938), (3) the rejection of claims 43 and 44 under 35 U.S.C.         

               1In the event of further prosecution, the examiner should              
          determine whether claim 38 is described within the meaning of 35            
          U.S.C. § 112, first paragraph.                                              
                                          5
