          Application No. 08/569,529                                                  


          In general, claims that are not argued separately stand or                  
          fall together.  In re Kaslow, 707 F.2d 1366, 1376, 217 USPQ                 
          1089, 1096 (Fed. Cir. 1983).  When the patentability of                     
          dependent claims in particular is not argued separately, the                
          claims stand or fall with the claims from which they depend.                
          In re King, 801 F.2d 1324, 1325, 231 USPQ 136, 137 (Fed. Cir.               
          1986); In re Sernaker, 702 F.2d 989, 991, 217 USPQ 1, 3 (Fed.               
          Cir. 1983).                                                                 


               Here, the appellants group claims 5, 6, and 7 with claim               
          1 and group claims 16 and 17 with claim 15.  (Appeal Br. at                 
          3.)   They fail to state, let alone explain, however, whether               
          claim 18 is believed to be separately patentable from claim                 
          15, from which it depends.  Therefore, we consider the claims               
          to stand or fall together in the following groups: claims 1                 
          and 5-7, claims 2-4, and claims 15-18.  We select claims 1, 2,              
          and 15 to represent the respective groups.  Next, we address                
          the obviousness of the claims.                                              


                              Obviousness of the Claims
