         Appeal No. 1997-3361                                                        
         Application No. 08/554,939                                                  


         U.S.C. § 103.  Accordingly, we affirm.  The reasons for our                 
         determination follow.                                                       
               As a preliminary matter, we note that the appellants urge             
         separate consideration for (1) claims 1, 7 through 9, and 21, (2)           
         claim 10, and (3) claims 16 through 18, 20, and 23.  (Appeal                
         brief, pages 6-7.)  Regarding group (3), however, the appellants            
         do not explain why these claims are separately patentable over              
         the claims of groups (1) and (2).  Merely pointing out                      
         differences in what the claims recite is not an argument as to              
         why they are separately patentable.  See 37 CFR § 1.192(c)(7)               
         (1995).  We therefore select claims 1 and 10 from the three                 
         groups of rejected claims and decide this appeal as to the                  
         examiner’s grounds of rejection on the basis of these claims                
         only.                                                                       
               We consider first the examiner’s rejection of claims 1, 7,            
         8, and 9 under 35 U.S.C. § 102 as anticipated by Kojima ‘370.               
         “To anticipate a claim, a prior art reference must disclose every           
         limitation of the claimed invention, either explicitly or                   
         inherently.”  In re Schreiber, 128 F.3d 1473, 1477, 44 USPQ2d               
         1429, 1431 (Fed. Cir. 1997); accord Glaxo Inc. v. Novopharm Ltd.,           
         52 F.3d 1043, 1047, 34 USPQ2d 1565, 1567 (Fed. Cir. 1995).  In              
         addition, the prior art reference must disclose the limitations             
         of the claimed invention “without any need for picking, choosing,           

                                         5
