          Appeal No. 95-3500                                                          
          Application No. 08/065,438                                                  


          35 U.S.C. § 112, second paragraph, for indefiniteness                       
          regarding the term “mass flow” as employed in step (e) of the               
          claims.                                                                     
               After having considered the entire record in light of the              
          respective positions advanced by appellants and the examiner,               
          we agree with appellants that the claims are sufficiently                   
          definite to comply with the second paragraph of 35 U.S.C. §                 
          112.  Accordingly, we shall reverse the rejection at issue.                 
               We entirely agree with appellants that, on their face,                 
          the claims clearly define which of the recited fluids is fed                
          to the energy production unit, namely the oxygen - depleted                 
          gas stream and the non-combustible fluid.  Moreover, as amply               
          demonstrated by appellants, the instant specification is                    
          replete with references to “mass flow” within the energy                    
          production unit and adequately discusses the significance of                
          each fluid input and output stream.  In this regard, pages 27,              
          29-30, 33-34, 37-38,                                                        
          42 and 56 are particularly pertinent.  The claims cannot be                 
          read in a vacuum but, rather, must be read in light of the                  
          instant specification as it would be interpreted by a person                
          possessing the ordinary level of skill in the pertinent art.                
                                          3
