                Appeal No. 95-2419                                                                                                          
                Application 07/850,770                                                                                                      


                        We also point out that appellants filed a Supplemental Information Disclosure                                       
                Statement on July 2, 1993 (Paper No. 14) citing Dirckx.  It does not appear that the                                        
                examiner has considered that paper.  Since Dirckx is concerned with mutation of                                             
                conserved N-glycosylation sites around the CD4-binding site of HIV-1 gp120, it may be                                       
                relevant in determining the patentability of the claims pending in this application.                                        
                        Again, upon return of the application, the appellants and the examiner should                                       
                consider Dirckx and determine what effect, if any, it has on the patentability of the claims                                
                pending in the application.  The examiner should also ensure that the record properly                                       
                reflects the outcome of that determination.                                                                                 
                        The decision of the examiner is affirmed.                                                                           
                        No time period for taking any subsequent action in connection with this appeal may                                  
                be extended under 37 CFR § 1.136(a).                                                                                        
                                                              AFFIRMED
