                     Appeal No. 2002-0441                                                                        Page 4                        
                     Application No. 09/273,152                                                                                                

                             Appellants argue that because Greczyn is drawn to a wax based system,                                             
                     it is not combinable with Lee.  We agree.                                                                                 
                             “In rejecting claims under 35 U.S.C. § 103(a), the examiner bears the                                             
                     initial burden of presenting a prima facie case of obviousness.  Only if that                                             
                     burden is met, does the burden of coming forward with evidence or argument                                                
                     shift to the applicant.”  In re Rijckaert, 9 F.3d 1531, 1532, 28 USPQ2d 1955,                                             
                     1956 (Fed. Cir. 1993).  The test of obviousness is “whether the teachings of the                                          
                     prior art, taken as a whole, would have made obvious the claimed invention.”  In                                          
                     re Gorman, 933 F.2d 982, 986, 18 USPQ2d 1885, 1888 (Fed. Cir. 1991).                                                      
                             Lee teaches cosmetic, antiperspirant compositions, while containing a                                             
                     silicone gel material, contain “no conventional waxy materials.”  Id. at Col. 2,                                          
                     lines 46-47; see also Col. 4, lines 48-52.  The cosmetic, antiperspirant                                                  
                     composition of Greczyn, on the other hand, requires in addition to the surface                                            
                     active agent, “one or more low melting wax-like materials in an amount in total of                                        
                     from about 12 to 20 percent by weight.”  Id. at Col. 5, lines 36-40.  Thus, when                                          
                     the prior art of record is considered as a whole, one of ordinary skill in the art                                        
                     would not combine the teachings of Lee, which teaches away from the use of                                                
                     waxy substances, with the teachings of Greczyn, which requires the use of a                                               
                     waxy substance.                                                                                                           
                             Moreover, as also argued by appellants, Greczyn teaches a broad range                                             
                     of surfactants, wherein the only criteria used in the choice of the nonionic                                              
                     surfactant is that it is a non-ionic ether or ester having an HLB value greater than                                      
                     10.  The examiner points to the teaching of polypropyleneglycol-5-ceteth-20
