          Appeal No. 98-0003                                                          
          Application No. 08/601,896                                                  


               The purpose of the requirement stated in the second                    
          paragraph of 35 U.S.C. § 112 is to provide those who would                  
          endeavor, in future enterprise, to approach the area                        
          circumscribed by the claims of a patent, with the adequate                  
          notice demanded by due process of law, so that they may more                
          readily and accurately determine the boundaries of protection               
          involved and                                                                
          evaluate the possibility of infringement and dominance.  In re              
          Hammack, 427 F.2d 1378, 1382, 166 USPQ 204, 208 (CCPA 1970).                
          For the reasons stated above, we do not believe claims 16 and               
          17 meet this requirement.                                                   


                                       Summary                                        


               The rejection of claims 1-4, 6-12, 16 and 17 as being                  
          unpatentable over Ouwerkerk in view of Karakane (rejection(a))              
          is affirmed, our affirmance being designated a new ground of                
          rejection under 37 CFR § 1.196(b).                                          





                                          14
