                Appeal No. 94-2410                                                                                                            
                Application 08/011,573                                                                                                        


                what “high” values are.   Chloupek desires “highly acidic”3                                                                                      
                catalysts and, as shown by Morrison, this type of catalyst has                                                                
                high alpha values.  Finally, Harandi does not disclose alpha                                                                  
                values but incorporates-by reference Morrison (column 1, line 66-                                                             
                column 2, line 2).  Therefore, the comments about Morrison apply                                                              
                also to Harandi.                                                                                                              
                         Accordingly, we agree with the examiner that low alpha value                                                         
                zeolite catalysts are known  but we find no reason or suggestion,4                                                                                
                other than from appellants’ specification, to use these catalysts                                                             
                in the disproportionation reactions of Chloupek, Morrison, or                                                                 
                Harandi.  Where the legal conclusion of obviousness is not                                                                    
                supported by facts, it cannot stand.  See In re Warner, 379 F.2d

                389 U.S. 1057 (1968).  For the foregoing reasons, we find that                                                                
                the examiner has not presented a sufficient factual basis to meet
