          Appeal No. 2000-0605                                                        
          Application No. 08/803,779                                                  


          the selected pieces from the references together in the manner              
          proposed by the examiner is found in the luxury of hindsight                
          accorded one who first viewed the appellant's disclosure.                   
          This, of course, is not a proper basis for a rejection.  See                
          In re Fritch, 972 F.2d 1260, 1266, 23 USPQ2d 1780, 1784 (Fed.               
          Cir. 1992).                                                                 
               Accordingly, we shall not sustain the examiner's                       
          rejection of independent claim 13, or of claims 2, 7-10 and                 
          14-17 which depend from claim 13, as being unpatentable over                
          Hillier in view of Kobayashi.                                               
                                    Rejection (2)                                     
               In making this rejection, the examiner implicitly                      
          concedes that Kobayashi does not teach or suggest the use of                
          the disclosed composition for use in containers of the type                 
          recited in claim 13.  The examiner, however, finds suggestion,              
          in the teaching by Mueller of blending a high molecular weight              
          stabilizer into the copolyester outer layer of a multi-layer                


               2(...continued)                                                        
          not, because of doubts that the invention is patentable, resort to          
          speculation, unfounded assumptions or hindsight reconstruction to supply    
          deficiencies in the factual basis. In re Warner, 379 F.2d 1011, 1017, 154 USPQ
          173, 177-78 (CCPA 1967).                                                    
                                          9
