                    Application No. 08/095,295                                                                                                                             


                              As is apparent from our patent jurisprudence (e.g., Valmont                                                                                  
                    Industries Inc. v. Reinke Manufacturing Co. Inc., 983 F.2d 1039,                                                                                       
                    1042, 25 USPQ2d 1451, 1454 (Fed. Cir. 1993)) and from the Manual                                                                                       
                    of Patent Examining Procedure (e.g., § 2182), the application of                                                                                       
                    a prior art reference to a "means plus function" limitation                                                                                            
                    requires (1) that the prior art element or structure perform the                                                                                       
                    identical function specified in the claim and (2) perform that                                                                                         
                    function using structure which is the same as or equivalent to                                                                                         
                    the structure disclosed in the specification.  If the prior art                                                                                        
                    fails to teach or suggest identity of function to that specified                                                                                       
                    in the claim and the element or structure of the prior art as                                                                                          
                    disclosed is not capable of performing such function, then the                                                                                         
                    inquiry is over and the prior art reference does not meet the                                                                                          
                    "means plus function" limitation specified in the claim.  Since                                                                                        
                    the snap fasteners (32, 33) of the Warren patent clearly do not                                                                                        
                    and can not perform the function specified in appellants' claim                                                                                        
                    33, it is clear that the examiner's rejection of claim 33 can not                                                                                      
                    be sustained.                                                                                                                                          


                    Given my determination that the snap fasteners (32, 33) of                                                                                             
                    Warren do not and can not perform the identical function                                                                                               
                    specified in claim 33 on appeal, I see no need to reach the issue                                                                                      

                                                                                   2929
