          Application No. 08/752,445                                                  


                    carrier extends to (claim 81), and that the                       
                    water closet provides support for (claim 82) the                  
                    off-the-floor water closet carrier, renders the                   
                    claims indefinite because the off-the-floor                       
                    water closet is not a positively recited element                  
                    of the claims.                                                    
                         Defining the width or other dimension of an                  
                    element of a subcombination with a direct                         
                    relationship to an element of a combination                       
                    where the claim is clearly intended to be drawn                   
                    to the subcombination renders the intended scope                  
                    of the claim indefinite.  The claim then fails                    
                    to distinctly define the metes and bounds of the                  
                    subject matter that will be protected by the                      
                    patent grant as required in the second paragraph                  
                    of 35 U.S.C. 112.                                                 
               Considering claim 66 as exemplary, it recites, inter                   
          alia:                                                                       
                         66.  A waste discharge system for at least                   
                    one off-the floor water closet having waste                       
                    discharge conduit means connected to waste                        
                    conduit junction means, the at least one off-                     
                    the-floor closet being in at least one of                         
                    adjacent rooms, each having a wall comprised of                   
                    consecutive, vertical studs, the walls providing

                         a water closet carrier comprised of front                    
                    and back structural means;                                        
                         wherein said water closet carrier is                         
                    adapted to be disposed within the walls of the                    
                    adjacent rooms;                                                   
                                *    *    *    *    *
