          Appeal No. 2004-0941                                                        
          Application No. 09/180,901                                                  


                                      Claim 17                                        


               We do not sustain the rejection of claim 17 under 35 U.S.C.            
          § 103(a) as being unpatentable over Manent in view of Shindo.5              
          The rejection of claims 18 and 19 is also not sustained since               
          these particular claims stand or fall with claim 17 as noted                
          above.                                                                      


               Independent claim 17 is drawn to an element for a revetment            
          with the features, inter alia, of two opposing transverse faces,            
          a first of the transverse faces having a concave shape with a               
          first radius and a second of the transverse faces having a convex           
          shape with the first radius, said second transverse face having a           
          concavity in an apex of the convex shape with a second radius               
          smaller than the first radius.                                              


               Simply stated, it is quite apparent to this panel of the               
          Board that the teachings of Manent and Shindo, by themselves,               
          would not have been suggestive of providing a concavity in the              


               5 We refer to the argument in the reply brief (page 3),                
          since appellant acknowledges that the argument in the main brief            
          addressed an old rejection.                                                 
                                          8
