                  Appeal  2006-2945                                                                                            
                  Application 10/041,958                                                                                       
                  of the evidence favors the Examiner’s conclusion that it “would have been                                    
                  further obvious to select antibodies against a single α or β subunit in view of                              
                  Perera[’s] . . . and Williams[’] demonstration of neutralizing monoclonal                                    
                  antibodies against these specific subunits” (Answer 6).                                                      

                  Secondary evidence of non-obviousness:                                                                       
                          Appellants direct our attention to several Declarations to demonstrate                               
                  that:                                                                                                        
                          1.  “neonatal gnotobiotic colostrum deprived piglets have a unique                                   
                  potential as a model to evaluate prophylactic or therapeutic approaches                                      
                  offering new advantages to prevent or lessen systemic complications of                                       
                  EHEC (enterohemorrhagic E. coli)[ ]      3  infection in humans” (Gunzer                                     
                  Declaration ¶ 5);                                                                                            
                          2. “the gnotobiotic piglet is the best model for evaluating therapies for                            
                  the prevention or treatment of tissue damage by STEC infection . . .” (Leong                                 
                  Declaration ¶ 4); and                                                                                        
                          3. “piglets are the only model which can be used to determine the                                    
                  therapeutic dose against the systemic effect of the Stx” (Tzipori Declaration                                
                  ¶ 4).  Nevertheless, Tzipiri declares that “[t]he exact injectable dose required                             
                  to establish this amount of antibody in the blood stream of human individual                                 
                  [to be fully protected against the development of HUS] will be determined in                                 
                  a dose-response study during phase I clinical trials” (Tzipori Declaration ¶                                 
                  5).                                                                                                          

                                                                                                                              
                  3 According to Appellants’ Specification “enterohemorrhagic Escherichia
