          Appeal No. 98-0541                                                          
          Application 08/409,137                                                      

          we--like the examiner--are persuaded that claim 12 complies                 
          with the description requirement of the first paragraph of                  
          35 U.S.C. § 112.                                                            
               It is true that the claims on appeal cover a rotary heat               
          exchanger and that appellant elected to prosecute only a                    
          modular heat exchanger following a restriction requirement in               
          the application which matured into the patent.  Had appellant               
          presented claim 12 in the application which matured into the                
          patent, he also would have been able to present the rejected                
          claims on appeal.  Appellant is not here attempting to claim                
          something he could not have claimed in the application which                
          matured into the patent.  Rather, through error, he failed to               
          present claim 12 during prosecution of the application which                
          matured into the patent sought to be reissued.  Since claim 12              
          is generic to both rotary and modular heat exchangers, and has              
          been found to be allowable, we perceive no reason why                       
          appellant should not also be able to present claims limited to              
          rotary heat exchangers.                                                     

               C.   Decision                                                          




                                        - 5 -
