                   Application 10/230,015                                                                                           
                           As evident by a review of the Briefs and the Answer, issues of                                           
                   overlapping ranges appear to be involved in at least several of the four                                         
                   anticipation rejections maintained by the Examiner.  See, for example, the                                       
                   paragraph bridging pages 4 and 5 and page 8 of the Answer and the                                                
                   Amended Brief at pages 10-12.                                                                                    
                           On December 20, 2005, the case of Perricone v. Medicis                                                   
                   Pharmaceutical Corp., 432 F.3d 1368, 77 USPQ2d 1321 (Fed. Cir. 2005)                                             
                   was decided.  Thereafter, Atofina v. Great Lakes Chem. Corp. 441 F.3d 991                                        
                   78 USPQ2d 1417 (Fed. Cir. 2006) was decided.  In those cases, our                                                
                   reviewing court addressed anticipation issues that appear to involve applied                                     
                   prior art that disclosed a component that is used in a process, in terms of                                      
                   ranges, as in Perricone, or a reactant and a process condition in terms of                                       
                   ranges, as in Atofina, as applied to claims that included corresponding                                          
                   narrower and/or overlapping range limitations for those items.1                                                  
                           Neither the Examiner nor the Appellants address the recent holdings                                      
                   in the Perricione and/or Atofina decisions with regard to the issues in the                                      
                   anticipation rejections advanced by the Examiner in this appeal.  In this                                        
                   regard, Atofina was decided after the Certificate of Mailing date (March 20,                                     
                   2006) associated with Appellants’ Reply Brief.                                                                   
                           Consequently, we remand this application to the Examiner to review                                       
                   those anticipation rejections in light of the recent Perricone and Atofina                                       
                   decisions.  The Examiner should submit a Supplemental Examiner’s Answer                                          
                   explaining how the respective holdings of our reviewing court in each of                                         
                   those cases (especially Atofina) can be regarded as being consistent with                                        
                                                                                                                                   
                   1 Also, see Section 2131.03 of the most recent edition (Rev. 5, Aug., 2006)                                      
                   of the Manual of Patent Examining Procedure.                                                                     
                                                                 2
