                Appeal 2006-2320                                                                               
                Application 10/061,830                                                                         

                      In view of the “means” recitations which specify the function but do                     
                not define structure which satisfies that function in appealed claims 8, 9, and                
                20, the strictures of 35 U. S. C. § 112, sixth paragraph, apply.  See Texas                    
                Digital Systems, Inc. v. Telegenx, Inc., 308 F.3d 1193, 1208,                                  
                64 USPQ2d 1812, 1822-23 (Fed. Cir 2002), and cases cited therein.                              
                Therefore, all of the “means” language in these appealed claims must be                        
                construed as limited to the “corresponding structure” disclosed in the written                 
                description in the Specification and “equivalents” thereof.  Donaldson, 16                     
                F.3d at 192-95, 29 USPQ2d at 1848-50.                                                          
                      The “corresponding structure” is that “structure in the written                          
                description necessary to perform that function [citation omitted],” that is,                   
                “‘the specification . . . clearly links or associates that structure to the                    
                function recited in the claims.’ [Citation omitted.]”  Texas Digital Systems,                  
                308 F.3d at 1208, 64 USPQ2d at 1822-23.  “[A] section 112, paragraph 6                         
                ‘equivalent[]’ . . . [must] (1) perform the identical function and (2) be                      
                otherwise insubstantially different with respect to structure. [Citations                      
                omitted.]”  Kemco Sales, Inc. v. Control Papers Co., 208 F.3d 1352, 1364,                      
                54 USPQ2d 1308, 1315-16 (Fed. Cir. 2000).  “[T]wo structures may be                            
                ‘equivalent’ for purposes of section 112, paragraph 6 if they perform the                      
                identical function, in substantially the same way, with substantially the same                 
                result. [Citations omitted.]”  Kemco Sales, 208 F.3d at 1364, 54 USPQ2d at                     
                1315.  “[T]he ‘broadest reasonable interpretation’ that an examiner may give                   
                means-plus-function language is that statutorily mandated in                                   
                [35 U.S.C. § 112,] paragraph six,” and in this respect, the examiner should                    
                not confuse “impermissibly imputing limitations from the specification into                    


                                                     - 4 -
