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



                     Claims 1, 2, 5, 6, 8 through 11, and 15 through 17 stand rejected under                             
              35 U.S.C. § 112, first paragraph (enablement).  We reverse.                                                
                                                     DISCUSSION                                                          
              The statement of the rejection is set forth on pages 5-7 of the examiner's answer.  In                     
              essence, the examiner would have appellants limit the claims on appeal to the specific                     
              vector described in the working examples of this application.  The examiner has set forth                  
              four separate reasons why the claims should be so limited.                                                 
                     In considering the four reasons, we find that the examiner has failed to take into                  
              account the proper legal standards in determining whether the subject matter of a given                    
              claim is enabled as required by 35 U.S.C. § 112, first paragraph.   As a consequence, the                  
              examiner has not engaged in the fact finding needed in order to properly reach a                           
              conclusion of non-enablement under this section of the statute.                                            
                     As set forth in In re Marzocchi, 439 F.2d 220, 223, 160 USPQ 367, 369 (CCPA                         
              1971), it is the examiner's initial burden to explain why one skilled in the art would doubt the           
              enabling statements set forth in the supporting specification of a patent application.  Here,              
              the examiner has focused on the working examples contained in the supporting                               
              specification and has not taken into account the broader statements contained in this                      


                     (...continued)2                                                                                                  
              in reaching our decision.                                                                                  

                                                            3
