          Appeal No. 2000-0104                                                        
          Application No. 08/850,647                                                  

          must disclose every limitation of the claimed invention,                    
          either explicitly or inherently”).                                          
               Cerola discloses two different arrangements for mounting               
          a catalyst member to the lens support structure of a contact                
          lens case: (1) the embodiment of Figs. 1 to 5, in which the                 
          rim of catalyst member 62 is engaged by tabs 88 for a                       
          “snapping engagement” (col. 5, line 50), and (2) the                        
          embodiment of                                                               
          Figs. 12 to 14, in which the catalyst member 90 has a                       
          “friction-type fit “(col. 6, line 23) over coupler 94 on the                
          bottom of lens support structure 40.  The catalyst member of                
          arrangement (1) is “easily removable and replaceable when                   
          desired” (col. 4, lines 43 to 45), and the catalyst member of               
          arrangement (2) is “readily removable for replacement by a                  
          user” (col. 6, lines 34 and 35).  The examiner asserts that                 
          the tabs of arrangement (1) and the friction fit of                         
          arrangement (2) constitute mechanical locks, as claimed                     
          (answer, part (11)).  While he does not mention the limitation              
          “for preventing removal of the catalyst member from said                    
          coupler” in the answer, he states on page 2 of the final                    
          rejection (Paper No. 17) that “[s]ince [Cerola] teaches all of
