                    Application No. 09/467,406                                                                                                                            

                              at least 2 deg. since this is a relative common angle                                                                                       
                              for wet shavers.  Regarding the slicing angle, the                                                                                          
                              angle of the Hadjopoulos edges are shown to be in the                                                                                       
                              range claimed by appellant (answer, page 3).                                                                                                
                    After a careful evaluation of the safety razor and blade                                                                                              
                    disclosed in the patent to Hadjopoulos, it is our opinion that                                                                                        
                    the examiner's reasoning in the rejection before us on appeal is                                                                                      
                    fraught with speculation and conjecture.  Thus, like appellant,                                                                                       
                    we find that the examiner has failed to meet his burden of                                                                                            
                    establishing a prima facie case of obviousness.                                                                                                       

                    In particular, we share appellant's view as aptly expressed                                                                                           
                    in the brief and reply brief regarding the examiner's position                                                                                        
                    that "it would appear likely that the shaving angle of the blades                                                                                     
                    [in Hadjopoulos] would be slightly above zero as shown in Figs.                                                                                       
                    1, 7 and would thus be either in or very close to the claimed 2

                    appear to be obvious to one of ordinary skill in the art that the                                                                                     
                    angle would be increased to at least 2 deg. since this is a

                    persuasive were the arguments presented by appellant in the reply                                                                                     
                    brief (Paper No. 15, filed July 27, 2001), to which the examiner                                                                                      
                    chose not to respond.  Since neither the applied reference nor
