          Appeal No. 1999-1454                                       Page 15           
          Application No. 08/596,343                                                   


          Appellants further assert (reply brief, pages 1 and 2) that                  
          element 1b of Hosen does not meet the limitations of claim 2                 
          with respect to the protection plate because 1b does not have                
          a CPU thereon.  Appellants further assert (id.) that element                 
          1c of Hosen does not have pillars called for in claim 2.                     
               The examiner takes the position (answer, page 4) that                   
          either insulating layer 1b or upper conductive layer 1c may be               
          considered a protection plate.  We disagree.  We find that in                
          Hosen (page 1), element 1a is a heat sink made of aluminum.                  
          Element 1b of Hosen is an insulating layer formed of epoxy                   
          resin.  Element 1c is a copper foil conductive pattern.  From                
          these teachings of Hosen, we find that the epoxy resin                       
          insulating layer does not constitute a plate.  Additionally,                 
          we find that although the power chip 2 of Hosen is provided on               
          the surface of conductive layer 1c, as are terminals (pillars)               
          7, we find that copper foil conductive patterns 1c cannot                    
          reasonable be construed as a protective plate.  We therefore                 
          conclude that neither epoxy resin insulating layer 1b nor                    
          copper foil conductive pattern 1c meet the claimed protective                
          plate, as advanced by the examiner.
