          Appeal No. 98-1499                                                          
          Application No. 08/392,493                                                  


          paragraph (i) of independent claims 1, 36, 42 and 46, and in                
          independent claim 47) is based on a misconception concerning                
          the nature of the heating and cooling fluid subchannel sets in              
          the face of each heat exchange plate, and that such error has               
          led to an inappropriate rejection of claims 1, 27, 36, 42, 44,              
          46 and 47 under 35 U.S.C. § 102(b) based on Takeshita, we will              
          not sustain this rejection.                                                 


          Each of the claims on appeal define a heat exchanger                        
          which includes a heat exchange plate or a plurality of heat                 
          exchange plates, wherein each of the plates has a front facial              
          surface and (A) a first heating fluid facial subchannel set                 
          comprising at least one heating fluid facial subchannel and                 
          (B) a first cooling fluid facial subchannel set comprising at               
          least one cooling fluid facial subchannel, with the first                   
          heating fluid facial subchannel set and the first cooling                   
          fluid facial subchannel set being mutually aligned in a first               
          heat exchange relationship on the common facial surface.  The               
          claims on appeal further set forth with regard to one                       
          embodiment covered thereby (e.g., (i) of claims 1, 36, 42 and               
          46) that said first heating fluid facial subchannel set and                 
                                          7
