          Appeal No. 2003-1632                                                        
          Application 09/173,991                                                      
          These include the verification and entry of the suitable                    
          cryptographic key which is discussed at columns 15 and 16                   
          relating to the public key system relied upon by Chaum                      
          specifically as taught there from the prior art discussion                  
          at column 5.  The acceptability or unacceptability of the                   
          bidirectional communications is discussed in greater detail in              
          the remaining parts of the reference and shown in figure 5.                 
          Table 1 at column 17 indicates the transmit identification is               
          identified in certain frames as well as the validity status as an           
          acknowledgment or nonacknowledgment capability of the respective            
          subelements communicating with each other.                                  
                    Since we have found that Chaum teaches within                     
          35 U.S.C. § 102 the disputed features of representative inde-               
          pendent claims 40 and 70 argued by appellants in the Brief and              
          Reply Brief, we sustain the rejection of respective independent             
          claims 40, 46, 70 and 73 rejected under 35 U.S.C. § 102 as well             
          as their corresponding dependent claims rejected under this                 
          statutory basis and under 35 U.S.C. § 103.  On the other hand, we           
          have not sustained the rejection of independent claims 56 and 60            
          under 35 U.S.C. § 102 and their corresponding dependent claims              
          rejected under 35 U.S.C. § 102 and 35 U.S.C. § 103.  As such, the           
          decision of the examiner is affirmed-in-part.                               

                                          9
