              Appeal No. 2006-1653                                                                 Παγε 3                                       
              Application No. 09/840,434                                                                                                        


                     We turn first to the examiner’s rejection of claims 1 to 6 and 9 under 35 U.S.C.                                           
              § 102(b) as being anticipated by Ichikawa.  We initially note that to support a rejection of                                      
              a claim under 35 U.S.C. § 102(b), it must be shown that each element of the claim is                                              
              found, either expressly described or under principles of inherency, in a single prior art                                         
              reference.  See Kalman v. Kimberly-Clark Corp., 713 F.2d 760, 772, 218 USPQ 781,                                                  
              789 (Fed. Cir. 1983), cert. denied, 465 U.S. 1026 (1984).  The examiner’s finding                                                 
              regarding this rejection can be found on 2 of the final rejection.                                                                
                     In regard to the recitation in claim 1 of the surface on the link which overlies low                                       
              profile sprocket protrusions along at least a majority of the length of the surface for                                           
              driving contact with the low profile protrusions, the examiner finds:                                                             
                            The Ichikawa references meets the limitations of the claims,                                                        
                            because the inner surface of the chain that contacts the                                                            
                            sprocket surface contacts more than half of the contact                                                             
                            surface.  In column 4 lines 20 to 33 Ichikawa discloses that                                                        
                            the low profile teeth of the sprocket 6" abut and support the                                                       
                            flat faces F.”  Figure 1 shows the low profile protrusion                                                           
                            contacting more than half the contact surface F of the chain                                                        
                            [answer at page 3].                                                                                                 
                     We will not sustain this rejection as to claim 1 because, in our view, the flat faces                                      
              F do not have a driving contact with the protrusions 6A, as required by claim 1.  We                                              
              agree with the appellants that:                                                                                                   
                            The chain of Ichikawa is driven by the guide plates 7 and the                                                       
                            articular train plates 2A that have sub-teeth that engage the                                                       
                            teeth (protrusions) of the sprocket.  Ichikawa col. 4 lines 1-5.                                                    
                            The surface F of plate 3 has no such sub-teeth and does
