          Appeal No. 97-1922                                                          
          Application No. 08/356,573                                                  

          appellants, “[t]he coating before or between the stretching                 
          operations implies that the polythiophene with conjugated                   
          polymer backbone has to withstand temperatures up to 200EC                  
          during heat setting and stretching without prohibitive                      
          coloration and without losing its conductivity” (page 3 of                  
          principal brief, second paragraph).                                         
               Appealed claims 1-12 stand rejected under 35 U.S.C. 103                
          as being unpatentable over Tanabe in view of Jonas.                         
               Upon careful consideration of the opposing arguments                   
          presented on appeal, we will not sustain the examiner’s                     
          rejection.                                                                  
               The examiner appreciates that Tanabe, who discloses a                  
          method of biaxially-orienting polyester film by stretching the              
          film in first and second directions, does not disclose coating              
          the presently claimed antistatic composition on the polyester               
          film, let alone before or between the first and second                      
          stretching operations.  While there is no dispute that Jonas                
          discloses coating appellants’ antistatic composition on a                   
          polyester sheet, there is no teaching in Jonas of applying the              
          antistatic composition either before stretching or between the              
          first and second stretching operations.  Hence, the issue                   

                                          3
