                  Appeal  2006-2945                                                                                            
                  Application 10/041,958                                                                                       
                  § 103(a) as unpatentable over the combination of Krivan, Perera, Williams,                                   
                  Queen and Engelman.  Claims 27 and 29 fall together with claim 28.                                           
                                                                                                                              
                  Claim 30:                                                                                                    
                          Claim 30 depends from and further limits the antibody of claim 26 to                                 
                  an antibody that binds the alpha subunit of the Shiga like toxin II.  Perera                                 
                  teaches “five monoclonal antibodies which bind to the α-subunit of SLT-II                                    
                  and were able to neutralize the toxin” (FF 7).                                                               
                          We recognize Appellants’ assertion that “[t]he prior art does not teach                              
                  administration of humanized (claim 27), recombinant (claim 28) or chimeric                                   
                  humanized antibodies (claim 29)” (Br. 29).  The prior art relied upon by the                                 
                  Examiner teaches administration of antibodies, and provides reasons why a                                    
                  person of ordinary skill in the art would seek to modified non-human                                         
                  antibodies to humanized, recombinant or chimeric forms.  Therefore, we are                                   
                  not persuaded by Appellants’ assertions.                                                                     
                          Accordingly, we affirm the rejection of claim 30 under 35 U.S.C.                                     
                  § 103(a) as unpatentable over the combination of Krivan, Perera, Williams,                                   
                  Queen and Engelman.  Claim 33 falls together with claim 30.                                                  

                  Claim 31:                                                                                                    
                          Claim 31 depends from and further limits the antibodies of claim 26 to                               
                  require that the antibodies are effective to prevent neurological signs of                                   
                  hemolytic uremic syndrome or lesions, wherein the neurological signs or                                      
                  lesions are selected from the group consisting of bloody diarrhea, acute                                     
                  renal failure, cerebral hemorrhaging, bacterial shedding into feces, bacterial                               
                  lesions, paddling, head-pressing, ataxia, convulsions and wasting.                                           

                                                              24
