          Appeal No. 2004-1872                                                        
          Application No. 09/886,183                                                  

          carbon monoxide)); In re Malagari, 499 F.2d 1297, 1303, 182 USPQ            
          549, 553 (concluding that a claimed invention was rendered prima            
          facie obvious by a prior art reference whose disclosed range                
          (0.020-0.035% carbon) overlapped the claimed range (0.030-0.070%            
          carbon)); see also In re Geisler, 116 F.3d 1465, 1469, 43 USPQ2d            
          1362, 1365 (acknowledging that a claimed invention was rendered             
          prima facie obvious by prior art reference whose disclosed range            
          (50-100 Angstroms) overlapped the claimed range (100-600                    
          Angstroms)).                                                                
               We determine that appellants’ claimed weight average                   
          molecular weight overlaps the range disclosed by Rehmer and                 
          therefore is rendered obvious by Rehmer.                                    
               In view of the above, we reject claims 7-10 and 16-19 under            
          35 U.S.C. § 103 as being obvious over Rehmer.                               
               This decision contains a new ground of rejection pursuant              
          to 37 CFR § 41.50(b)(effective September 13, 2004, 69 Fed. Reg.             
          49960 (August 12, 2004), 1286 Off. Gaz. Pat. Office 21                      
          (September 7, 2004)).  37 CFR § 41.50(b) provides “[a] new                  
          ground of rejection pursuant to this paragraph shall not be                 
          considered final for judicial review.”                                      
               37 CFR § 41.50(b) also provides that the appellants, WITHIN            
          TWO MONTHS FROM THE DATE OF THE DECISION, must exercise one of              
          the following two options with respect to the new ground of                 
          rejection to avoid termination of the appeal as to the rejected             
          claims:                                                                     
                    (1) Reopen prosecution.  Submit an appropriate                    
               amendment of the claims so rejected or new evidence                    
               relating to the claims so rejected, or both, and have                  
               the matter reconsidered by the examiner, in which                      
               event the proceeding will be remanded to the examiner                  
               . . . .                                                                


                                          6
