          Appeal No. 96-3032                                                          
          Application No. 08/321,392                                                  


          that as expressly set forth in 37 CFR § 1.192(c)(7): "Merely                
          pointing out differences in what the claims cover is not an                 
          argument as to why the claims are separately patentable."                   
               We have carefully reviewed the appellants' invention as                
          described in the specification, the appealed claims, the prior              
          art applied by the examiner and all of the respective                       
          arguments advanced by the appellants in the brief and by the                
          examiner in the answer.  As a consequence of this review, we                
          will sustain both of the above-noted rejections.                            
               Initially we note that while the obviousness of an                     
          invention cannot be established by combining the teachings of               
          the prior art absent some teaching, suggestion or incentive                 
          supporting the combination (see, e.g., ACS Hospital Systems,                
          Inc. v. Montefiore Hospital, 732 F.2d 1572, 1577, 221 USPQ                  
          929, 933 (Fed. Cir. 1984)), this does not mean that the cited               
          references or prior art must specifically suggest making the                
          combination (B.F. Goodrich Co. V. Aircraft Braking Systems                  
          Corp., 72 F.3d 1577, 1582, 37 USPQ2d 1314, 1318 (Fed. Cir.                  
          1996) and In re Nilssen, 851 F.2d 1401, 1403, 7 USPQ2d 1500,                
          1502 (Fed. Cir. 1988)).  Instead, obviousness may be                        


                                          4
