               Appeal No. 1996-3791                                                                                                   
               Application 08/028,087                                                                                                 


               G-CSF to the lungs of mammals (Examiner’s Answer, page 5).                                                             
                       We need not determine whether the references establish a prima facie case of                                   
               obviousness.  Appellants have relied upon rebuttal evidence in response to this new                                    
               ground of rejection (Reply Brief, page 5).  As stated in In re Hedges, 783 F.2d 1038,                                  
               1039, 228 USPQ 685, 686 (Fed. Cir. 1986):                                                                              
                       If a prima facie case is made in the first instance, and if the applicant                                      
                       comes forward with reasonable rebuttal, whether buttressed by                                                  
                       experiment, prior art references, or argument, the entire merits of the                                        
                       matter are to be reweighed.  In re Piasecki, 745 F.2d 1468, 1472, 223                                          
                       USPQ 785, 788 (Fed. Cir. 1984).                                                                                
               We find no response by the examiner indicating that the rejection was reconsidered in                                  
               light of this rebuttal evidence.  The Supplemental Examiner’s Answer (Paper No. 23)                                    
               does not acknowledge or take into account this portion of appellants’ position.  This is                               
               legal error on the examiner’s part.                                                                                    















                                                                  5
