          Appeal No. 97-3294                                                          
          Application 08/408,225                                                      



                    A consideration of the content of parent claim 1 and              
          claim 6 reveals to us that the subject matter of claim 6 is                 
          definite in meaning, i.e., the metes and bounds of the claimed              
          subject matter is determinable, as explained below.                         
                    Claim 1 is drawn to a combination.  As set forth                  
          in claim 1, the combination includes a defined device and a                 
          retainer.  No language is present in claim 1 reflecting that                
          the combination is restricted exclusively to the device and                 
          retainer.  Thus, the language in dependent claim 6, i.e,                    
          “[t]he                                                                      




          combination of claim 1 further comprising an instrument”,                   
          simply and clearly sets forth, from our perspective, the                    
          instrument as an additional entity of the open-ended                        
          combination of claim 1. Accordingly, we perceive claim 6 to be              
          readily understandable and, hence, definite under 35 U.S.C. §               
          112, second paragraph.                                                      


                               The anticipation issue                                 

                                          5
