          Appeal No. 2001-0611                                                        
          Application No. 08/742,733                                                  


          in accordance with 37 CFR § 1.192(c)(7), we have selected claim             
          19 as it depends from claim 11 (hereinafter denominated claim               
          19/11) as representative of claims 18, 19 and 20.                           
               Claim 19/11 further limits the orthopedic implant of claim             
          11 by specifying that the claim 11 implant comprises a first                
          piece and a second piece, with the first and second pieces being            
          joined and locked together by an interlocking means.  The                   
          interlocking means is further defined as comprising a protruding            
          member on the first piece and a cavity on the second piece for              
          receiving the protruding member.                                            
               Looking once again to the teachings of the applied                     
          references, Goble teaches an implant comprising a first piece 12            
          and a second piece 11, and interlocking means in the form of a              
          protruding member 14 on the first piece and a cavity 13 on the              
          second piece for receiving the protruding member to join and lock           
          the pieces together.  Moumene teaches a bone implant made of                
          thermoplastic material having an elastic modulus approximating              
          the elastic modulus of bone to provide a strong and durable                 
          implant, and Bokros teaches a bone implant having a biocompatible           
          material (i.e., coils 32) partially embedded in the surface of              
          the implant (see column 4, lines 9-12) to promote the ingrowth of           


                                         15
