             Appeal No. 95-0969                                                                                   
             Application 07/945,586                                                                               


             rejection will be reversed.                                                                          
                    Terada discloses a water-in-oil emulsion wherein the aqueous                                  
             phase is about 5-50 wt% of the emulsion (col. 1, line 65 - col.                                      
             2, line 6).  The emulsion contains a polyhydric alcohol fatty                                        
             acid ester which is made using an unsaturated fatty acid or a                                        
             mixture of unsaturated and saturated fatty acids (col. 2, line 67                                    
             - col. 3, line 8).  The preferred amount of unsaturated fatty                                        
             acid is at least about 50 wt% of the combined fatty acids, and                                       
             the unsaturated fatty acids which are disclosed as being suitable                                    
             include erucic acid (col. 3, lines 15-17 and 22-26).  The                                            
             polyhydric alcohol unsaturated fatty acid ester is present in an                                     
             amount of 0.25 to 2.5 wt% of the emulsion (col. 3, lines 31-34).                                     
                    To arrive at appellants’ polyglycerol fatty acid ester from                                   
             the teaching of Terada, one would have to: 1) select an amount of                                    
             unsaturated fatty acid which is at least 70 wt% of the combined                                      
             fatty acid, 2) select erucic acid from the eight listed                                              
             unsaturated fatty acids (col. 3, lines 22-26), 2) select a                                           
             polyglycerol, which is not among the polyhydric alcohols listed                                      
             by Terada (col. 3, lines 26-30), as the polyhydric alcohol, and                                      
             3) select an esterification ratio of 30-90%.  In our view, the                                       
             teaching by Terada would not have fairly suggested this                                              
             combination of selections to one of ordinary skill in the art.                                       

                                                       -3-3
