          Appeal No. 2003-1285                                                        
          Application 09/751,513                                                      


          2003) for a complete exposition of the examiner’s position and to           
          appellant’s brief (Paper No. 10, filed December 31, 2002) for the           
          arguments thereagainst.                                                     


               0PINION                                                                


          Having carefully reviewed the anticipation issues raised in                 
          this appeal in light of the record before us, we have come to the           
          conclusion that the examiner's rejection of the appealed claims             
          under 35 U.S.C. § 102(b) will be sustained with regard to claims            
          1, 2 and 4 through 8, but not with regard to claims 3 and 9                 
          through 17.  Our reasoning in support of these determinations               
          follows.                                                                    


          In rejecting claims 1 through 17 under 35 U.S.C. § 102(b)                   
          the examiner specifically directs us to Figure 6 of the Horton              
          patent, urging (final rejection, page 2) that we note driving               
          surfaces (86) and (87) of the sprocket (84) shown therein.  The             
          examiner then makes the following observations concerning the               
          drive sprocket of Figure 6:                                                 
               The fact that the sprocket always has both driving surfaces            
               means that the sprocket inherently will drive both the                 
               center rib and the link ends contrary to the impression                
                                          3
