            Appeal No. 2004-0918                                                          Page 5              
            Application No. 09/715,547                                                                        


            describe performance of the claimed function.  See Al-Site, 174 F.3d at 1318, 50                  
            USPQ2d at 1167.                                                                                   


                   Because the claimed "accommodating means" of claim 24 uses the word                        
            "means," we presume that 35 U.S.C. § 112, paragraph 6 applies.  We next look to                   
            whether the claimed "accommodating means" of claim 24 specifies a function.  In                   
            making this determination, we rely primarily on the claim language itself.  See York              
            Prods., Inc. v. Central Tractor, 99 F.3d 1568, 1574, 40 USPQ2d 1619, 1624 (Fed. Cir.              
            1996).  After reviewing the language of the claimed "accommodating means" of claim                
            24, we reach the determination that it specifies the function of accommodating within             
            the receiving space of the frame both (1) the audio or light mixer; and (2) the audio or          
            light effect device.  In sum, the claimed "accommodating means" of claim 24 does                  
            warrant interpretation under 35 U.S.C. § 112, paragraph 6.                                        


                   As explained in In re Donaldson, 16 F.3d 1189, 1193, 29 USPQ2d 1845, 1848-49               
            (Fed. Cir. 1994), the USPTO is not exempt from following the statutory mandate of                 
            35 U.S.C. § 112, paragraph 6, which reads:                                                        
                   An element in a claim for a combination may be expressed as a means or step                
                   for performing a specified function without the recital of structure, material, or         
                   acts in support thereof, and such claim shall be construed to cover the                    
                   corresponding structure, material, or acts described in the specification and              
                   equivalents thereof.
