              Appeal No. 95-2208                                                                                         
              Application 07/987,572                                                                                     



                     (Fed. Cir. 1984).  The Patent and Trademark Office Board of Appeals                                 
                     summarized the point well when it stated:                                                           
                            The test is not merely quantitative, since a considerable                                    
                            amount of experimentation is permissible, if it is merely                                    
                            routine, or if the specification in question provides a                                      
                            reasonable amount of guidance with respect to the direction in                               
                            which the experimentation should proceed to enable the                                       
                            determination of how to practice a desired embodiment of the                                 
                            invention claimed.                                                                           
                     Ex parte Jackson, 217 USPQ 804, 807 (1982).                                                         
                     Absent a more fact-based explanation of the rejection premised upon the correct                     
              legal standards, we do not find that the examiner has carried his initial burden of                        
              establishing reasons of unpatentability.  In re Oetiker, 977 F.2d 1443, 1446, 24 USPQ2d                    
              1443, 1445 (Fed. Cir. 1992).  As a consequence, we reverse the rejection under 35                          
              U.S.C. § 112, first paragraph (enablement).                                                                
                     The decision of the examiner is reversed.                                                           
                                                     REVERSED
