              Appeal No. 1995-2036                                                                                         
              Application 07/920,009                                                                                       



              high amount of aromatic polycarbonate (at least about 15 parts by weight or about 15                         
              percent by weight).                                                                                          
                     The examiner argues that (1) Fromuth, in column 1, lines 12 through 23, discusses                     
              Nakamura, U.S. Patent No. 3,864,428, and (2) according to Fromuth, Nakamura discloses                        
              a relatively high amount of aromatic polycarbonate in its polymeric blends.  The examiner,                   
              however, does not cite or rely on the Nakamura patent in setting forth a prior art rejection                 
              before us.  The examiner relies on Fromuth's discussion or characterization of Nakamura,                     
              but Fromuth does not indicate the relative amounts of aromatic polyester or butadiene-                       
              based core-shell polymer in the polymeric blends disclosed by Nakamura.  On these facts,                     
              we find that Fromuth's discussion of Nakamura constitutes insufficient evidence to support                   
              a conclusion of obviousness or claims 3, 4, 9 through 11, 16, 17, and 21 through 25 which                    
              enumerate the relative amounts of each component in the claimed thermoplastic                                
              composition.                                                                                                 
                     The examiner also argues that several comparative examples disclosed by                               
              Fromuth include a relatively high amount of aromatic polycarbonate, for example, 15                          
              percent by weight, which meets the amount of aromatic polycarbonate resin recited in                         
              claims 3, 4, 9 through 11, 16, 17, and 21 through 25.  The examiner has not established,                     
              however, that any comparative example described by Fromuth would have led to a                               
              thermoplastic composition defined in claims 3, 4, 9 through 11, 16, 17, and                                  

                                                            7
