         Appeal No. 2003-0905                                                       
         Application No. 09/781,426                                                 

              We note that on page 3 of the Brief, appellants discuss a             
         35 U.S.C. § 112, second paragraph, rejection.  On page 3 of the            
         answer, the examiner indicates that this rejection has been                
         withdrawn.                                                                 
              Therefore, the sole issue on appeal is the rejection of               
         claims 36 through 50 under the judicially created doctrine of              
         obviousness-type double patenting as being unpatentable over               
         claims 1 through 18 of U.S. Patent No. 6,004,993.                          
              The examiner relies on the following reference as evidence            
         of unpatentability:                                                        
         Steiner et al. (Steiner)        6,004,993         Dec. 21, 1999            

              At the bottom of page 2 of the Brief, appellants state that           
         the grouping of claims under the judicially created doctrine of            
         obviousness-type double patenting rejection stands or falls                
         together.  We therefore consider claim 36, the broadest claim on           
         appeal.  37 CFR § 1.192(c)(7) and (c)(8) (2001).                           


                                      OPINION                                       
              We have carefully reviewed appellants’ Brief and the                  
         examiner’s Answer.  This review has led us to conclude that the            



                                        -2-
