                Appeal 2007-0843                                                                             
                Application 09/725,393                                                                       
                respect to this rejection have treated these claims as a single group which                  
                stand or fall together, we will select independent claim 1 as the                            
                representative claim for this rejection because it is the broadest independent               
                claim in this group.  See 37 C.F.R. § 41.37(c)(1)(vii)(2004).                                
                      Appellants argue that Bruckman fails to teach or suggest at least                      
                puncturing and/or repeating channel coded packets to produce a first sub-                    
                packet based on a size of the encoder packet, as set forth in claim 1.                       
                Appellants argue that Bruckman at most discloses the fragmenting (i.e.,                      
                dividing) of packets into pieces based on a transmission rate over a channel,                
                where the optimal fragment length is based on considerations of overhead                     
                and maximum permitted delay.  Appellants argue the actual size of the                        
                datagram received at the transmitter front end merely triggers the                           
                fragmenting of a received datagram and is not used in determining the size                   
                of the packet fragments.  Appellants acknowledge that when an input packet                   
                from “sources 26” exceeds a determined fragment size, “fragmenter 28”                        
                divides the packet for transmission into multiple fragments (see Bruckman, ¶                 
                0026, ll. 9-11).  Nevertheless, Appellants conclude that the input packet size               
                is not used in determining the size of the packet fragments (Br. 15-16).                     
                      In the Reply Brief, Appellants further argue that the fragmenting of                   
                Bruckman does not constitute the recited “puncturing” (claim 1).  Appellants                 
                argue the claimed “puncturing” involves dropping bits (id.).  Appellants                     
                assert that Bruckman merely teaches fragmenting or slicing an input                          
                fragment into multiple smaller fragments (Reply Br. 3).                                      
                      In response, the Examiner agrees that the size of the sub-packets in                   
                Bruckman is based on the transmission frequency.  However the Examiner                       


                                                     4
