                 Application No.  08/524,206                                                                             
                                                     DISCUSSION                                                          
                 THE REJECTION UNDER 35 U.S.C. § 112, FIRST PARAGRAPH:                                                   
                        According to the examiner (Answer, page 6), “[t]he specification does not                        
                 enable any person skilled in the art to make and use the invention commensurate                         
                 in scope with the current claims.”  The examiner did not argue the claims                               
                 separately therefore for the reasons set forth above we limit our discussion to                         
                 representative independent claim 1.                                                                     
                        With reference to Uhlmann, Milligan, Stein and Tseng the examiner finds                          
                 (Answer, page 7), “[a]t the time the application was filed therapeutic                                  
                 administration of oligonucleotides to an animal or human subject by any route                           
                 was considered by those skilled in the art to be an undeveloped and                                     
                 unpredictable method of treatment….”  However, in contrast to the claimed                               
                 invention, each of the references relied upon by the examiner are drawn to anti-                        
                 sense therapies.  Reply Brief, page 6.  Apparently recognizing this deficiency in                       
                 the references, the examiner simply concludes (Answer, page 7):                                         
                        The obstacles to providing sufficient mRNA-binding                                               
                        oligonucleotides to a patient’s cells … are even greater for the                                 
                        claimed method, wherein the DNA molecules are targeted to a                                      
                        DNA-binding protein, because the affinity of oligonucleoties for their                           
                        complementary target mRNAs is expected to be greater than the                                    
                        affinity of double-strand DNAs for their binding site of the protein.                            
                 However, as appellants recognize (Reply Brief, page 6), “the [e]xaminer provided                        
                 no evidence to support this statement.”  We remind the examiner that our                                
                 reviewing court has held that findings of fact must be supported by substantial                         
                 evidence within the record.  In re Gartside, 203 F.3d 1305, 1315, 53 USPQ2d                             
                 1769, 1775 (Fed. Cir. 2000) (“because our review of the board’s decision is
