          Appeal No. 1998-2831                                      Page 15           
          Application No. 08/541,013                                                  


          § 112 to ascertain whether the structure of Holmes (e.g., the               
          ridge 40d of trigger 40) is or is not an "equivalent" of the                
          structure disclosed by the appellants, we conclude that the                 
          structure of Holmes is not an "equivalent" of the structure                 
          disclosed by the appellants.  In that regard, it is clear to                
          us that the structure of Holmes does not perform the function               
          specified in the claim in substantially the same way, and does              
          not produce substantially the same result as the corresponding              
          elements disclosed by the appellants.  Furthermore, it is our               
          view that a person of ordinary skill in the art would not have              
          recognized the interchangeability of the elements shown in the              
          prior art for the corresponding elements disclosed in the                   
          appellants' specification.  Based upon the above                            
          determinations, we conclude that there are substantial                      
          differences between the structure of Holmes and the structure               
          disclosed by the appellants.  Accordingly, under the above-                 
          noted tests for determining equivalence under the sixth                     
          paragraph of                                                                
          35 U.S.C. § 112 we conclude that the structure in Holmes                    
          (e.g., the ridge 40d of trigger 40) is not equivalent to the                
          structure disclosed by the appellants.
