          Appeal No. 95-3876                                                           
          Application 08/222,009                                                       

          Iwata.  Appellants do not argue that if the function of                      
          "removing the enabling voltage" is performed by the control                  
          voltage generation circuit 18 in Iwata, the structure for                    
          performing the function in Iwata is not the same as or an                    
          equivalent of appellants' under § 112, sixth paragraph.  In my               
          opinion, as a matter of procedure, we should not address the                 
          question of structure under § 112, sixth paragraph, unless                   
          argued by appellants in the first instance.  See Examination                 
          Guidelines for Claims Reciting a Means or Step Plus Function                 
          Limitation In Accordance With 35 U.S.C. § 112, 6th Paragraph,                
          1162 Off. Gaz. Pat. & Trademark Office 59, 59-60                             
          (May 17, 1994) (the examiner initially makes a prima facie                   
          case that a limitation is anticipated by showing that a prior                
          art structure performs the function, then the burden of going                
          forth with the evidence shifts to applicant to show that the                 
          prior art structure is not the same as or an equivalent of the               
          structure, material, or acts described in the specification);                
          37 CFR § 1.192(c)(6)(iv) (1994) ("For each rejection under                   
          35 U.S.C.                                                                    
          103, the argument shall specify the errors in the rejection,                 
          the specific limitations in the rejected claims which are not                

                                        - 25 -
