                Appeal 2007-0321                                                                                 
                Application 10/669,547                                                                           

                phrase “consisting essentially of” encompasses the compositions suggested                        
                by the references.                                                                               
                       Appellants argue that the Examiner’s reliance on Ex parte Obiaya,                         
                227 USPQ 58 (BPAI 1985), is improper because the Examiner has not                                
                established a prima facie case of obviousness, as required by Obiaya (Br.                        
                12).                                                                                             
                       For the reasons discussed above, we do not agree that the Examiner                        
                has failed to establish the prima facie obviousness of claim 16.  Instead, we                    
                agree with the Examiner that one of ordinary skill would have considered it                      
                obvious to pre-treat a chemical depilation site with a composition having                        
                90% lipophilic material.  We therefore affirm the Examiner’s rejection of                        
                claim 16.                                                                                        
                4.  OBVIOUSNESS -- CLAIMS 7, 12-15, and 17                                                       
                       Claims 7, 12-15, and 17 stand rejected under 35 U.S.C. § 103 as                           
                obvious over LaHann, Michaels, and Orlow (Answer 6-9).                                           
                       The Examiner again cites the combination of LaHann and Michaels as                        
                suggesting treating skin with an anti-irritant composition having 90%                            
                lipophilic materials before chemical depilation (id. at 6-7).  The Examiner                      
                concedes that LaHann does not specifically mention placing the pretreatment                      
                and depilatory compositions in a kit as recited in claim 7, but cites Orlow as                   
                teaching that “it is a well known practice in personal care composition art to                   
                package the products with a printed instructions as a label or package insert                    
                directing the use of such composition” (id. at 8).                                               
                       We agree with the Examiner that one of ordinary skill would have                          
                considered it obvious to package a pretreatment composition comprising
