                 Application No.  10/164,863                                                                             
                 SR-BI knockout mice are not a representative animal model for evaluating “[a]                           
                 method of treating reproductive disorders involving abnormal levels of lipids in a                      
                 female mammal mediated by SR-BI activity.”  See e.g., claim 1.                                          
                        “When rejecting a claim under the enablement requirement of section 112,                         
                 the PTO bears an initial burden of setting forth a reasonable explanation as to                         
                 why it believes that the scope of protection provided by that claim is not                              
                 adequately enabled by the description of the invention provided in the                                  
                 specification of the application; this includes, of course, providing sufficient                        
                 reasons for doubting any assertions in the specification as to the scope of                             
                 enablement.”  In re Wright, 999 F.2d 1557, 1561-62, 27 USPQ2d 1510, 1513                                
                 (Fed. Cir. 1993).  “[It] is incumbent upon the Patent Office, whenever a rejection                      
                 on this basis is made, to explain why it doubts the truth or accuracy of any                            
                 statement in a supporting disclosure and to back up assertions of its own with                          
                 acceptable evidence or reasoning which is inconsistent with the contested                               
                 statement.  Otherwise, there would be no need for the applicant to go to the                            
                 trouble and expense of supporting his presumptively accurate disclosure.”                               
                 In re Marzocchi, 439 F.2d 220, 224, 169 USPQ 367, 370 (CCPA 1971).  Upon                                
                 consideration of the record, we find no evidence to support the examiner’s                              
                 arguments.                                                                                              
                        In our opinion, the examiner fail to meet his burden of providing the                            
                 evidence necessary to support his position.  The examiner also asserts (Answer,                         
                 page 4), “[t]here is no evidence [on this record] that altering SR-BI levels in a                       
                 fertile female with normal SR-BI levels and no reproductive disorders will have
