          Appeal No. 96-2994                                                           
          Application 08/282,413                                                       


          (Fed. Cir. 1987).  Since the dependent claims have not been                  
          properly argued for separate patentability, such claims will                 
          stand or fall with the claims from which they depend.  Note                  
          In re King, 801 F.2d 1324, 231 USPQ 136 (Fed. Cir. 1986);                    
          In re Sernaker, 702 F.2d 989, 217 USPQ 1 (Fed. Cir. 1983).                   
          Accordingly, we will consider the rejection against                          
          independent claims 1 and 14 as representative of all the                     
          claims on appeal before us.                                                  


          In rejecting claims under 35 U.S.C. § 103, it is                             
          incumbent upon the examiner to establish a factual basis to                  
          support the legal conclusion of obviousness.  See In re Fine,                
          837 F.2d 1071, 1073, 5 USPQ2d 1596, 1598 (Fed. Cir. 1988).  In               
          so doing, the examiner is expected to make the factual                       
          determinations set forth in Graham v. John Deere Co., 383 U.S.               
          1, 17, 148 USPQ 459, 467 (1966), and to provide a reason why                 
          one having ordinary skill in the pertinent art would have been               
          led to modify the prior art or to combine prior art references               
          to arrive at the claimed invention.  Such reason must stem                   
          from some teaching, suggestion or implication in the prior art               
          as a whole or knowledge generally available to one having                    
                                          5
