                Appeal 2007-0321                                                                                 
                Application 10/669,547                                                                           

                capsaicin, in LaHann’s compositions demonstrates that it is a chemically                         
                active agent, whereas the lipophilic materials in the claimed process “are                       
                believed to coat the skin thereby serving as a blanket protection against the                    
                subsequent application of caustic depilatory.  The depilatory ‘sees’ the                         
                keratin fibers but is shielded by the lipophilic materials from contact with                     
                underlying skin” (Br. 8).  Appellants argue that because LaHann “attenuates                      
                irritation through the chemical means of capsaicin” as opposed to using “a                       
                physical blanket of lipophilic materials to separate the harsh depilatory from                   
                the skin but not from the keratin fiber . . .[,] LaHann et al. does not                          
                appreciate the physical approach nor suggest[] using extremely high levels                       
                of lipophilic materials” (id. at 9).                                                             
                       We are not persuaded by these arguments.  It is well settled that                         
                “[n]on-obviousness cannot be established by attacking references                                 
                individually where the rejection is based upon the teachings of a                                
                combination of references. . . .  [The reference] must be read, not in                           
                isolation, but for what it fairly teaches in combination with the prior art as a                 
                whole.”  In re Merck & Co., 800 F.2d 1091, 1097 (Fed. Cir. 1986).                                
                       In the instant case, LaHann is relied on in combination with Michaels.                    
                As discussed above, although LaHann does not teach using a composition                           
                containing claim 1’s amount of lipophilic material as a chemical depilation                      
                pretreatment, Michaels discloses that a composition containing lipophilic                        
                material in a percentage very close to that recited in claim 1 has a soothing                    
                effect on skin when used as a paint remover or shaving pretreatment.  Thus,                      
                because claim 1 has been rejected over the combination of LaHann and                             



                                                       8
