          Appeal No. 97-1176                                                          
          Application 08/003,673                                                      


          found objectionable by the examiner read as follows:                        
               . . . [T]he [water treatment] material is in solid or                  
               paste form and fills the interior of the cartridge 15                  
               so that essentially only its upper surface makes                       
               effective contact with water, the apertures 27 being                   
               sufficiently small so that the contact between the                     
               water and the material 34 by virtue of the holes 27,                   
               does not have any significant effect on the dissolving                 
               or dispersion of the material 34.  The material is                     
               desirably formulated so that it slowly dissolves in                    
               water, the pattern of holes 27 being effective to                      
               ensure that the material 34 is consumed evenly, so that                
               its upper surface maintains a substantially flat                       
               profile as it slowly drops.  [specification, page 7,                   
               lines 17-27; emphasis added]                                           
                                    *     *     *                                     
                    As the water treatment material 34 is consumed and                
               the level of its upper surface drops, further apertures                
               27 in the side wall of the cartridge casing 25 become                  
               exposed to thereby permit water collected within the                   
               casing to drain therefrom during the flushing cycle.                   
               Desirably, water within the housing 11 makes contact                   
               with the water treatment material essentially only                     
               across its upper surface, thus permitting the rate of                  
               dispersion of the water treatment material 34 to be                    
               effectively controlled.  [specification, page 8, lines                 
               23-31; emphasis added]                                                 
               In our view, the ordinary skilled artisan would have no                
          difficulty determining the metes and bounds of claim 15, and in             
          particular the language pointed out by the examiner, when the               
          claim language is read in light of the foregoing portions of                
          appellants’ disclosure.  Accordingly, we will not sustain the               



                                         -6-
