             Appeal No. 2006-2529                                                                                
             Application No. 10/428,792                                                                          

             second end is a stem 26 which extends into the barrel on the breech end.  The                       
             diameter of the stem is described in the following way:                                             
                   The outer diameter of the free end portion 26 is substantially less than                      
                   the inner diameter of the nipple bore 54 so that the outer surface 28 of                      
                   the nipple is spaced from the inner surface 56 of the nipple bore to                          
                   form an annular auxiliary fire channel 72 extending from the side fire                        
                   channels 42 to the powder well 50.  (Col. 3, lines 54-59).                                    
             Therefore, as readily can be seen, the stem of Laney is of uniform diameter and                     
             forms a cavity between the diameter of the stem and the barrel.  Lastly, Laney has                  
             a bore that extends longitudinally through the entire breech plug.                                  
                                                  ANALYSIS                                                       
                   Appellant argues that Laney fails to disclose a cavity formed between the                     
             outer diameter of the stem and the inner diameter of the bore. We must emphasize                    
             that Laney does disclose such a cavity.  It might be argued that the cavity of Laney                
             is not between the stem and the barrel but between the stem and Laney’s breech                      
             plug 68.  However, the claim does not preclude the presence of another member                       
             (the breech plug) between the barrel and the stem.  Therefore, the cavity 72 is                     
             physically located between the stem and the barrel.                                                 
                   In the reply, appellant argues that Laney fails to show a stem of uniform                     
             diameter extending outwardly from the second end of the body as required by the                     
             claim.  Here again, we must note that the stem extends out of the body 22 with a                    
             threaded portion 27 juxtaposed between the stem and the body.  As noted above,                      
             the claim, in “comprising” language, does not preclude the addition of the threaded                 
             portion 27, inasmuch as Laney discloses a nipple, a body, and a stem.  In other                     
             words, the threaded portion 27 is not precluded by the claim language of claim 1.                   
                                                       3
