          Appeal No. 1998-1053                                                        
          Application No. 07/974,832                                                  


          appellant has urged that the term "determinative" found                     
          confusing by the examiner, when read in light of the                        
          specification,                                                              
               clearly means parameters which can be used to                          
               determine a particular feature, but do not                             
               constitute that feature itself.  It is respectfully                    
               submitted that the Examiner's attempt to ignore this                   
               language and include direct measurement of the                         
               features of interest within this definition would                      
               render the estimating step confusing, since an                         
               estimated feature would clearly not be needed if a                     
               direct measurement thereof was provided (page 2).                      

          However, during the oral hearing held July 11, 2000,                        
          appellant's counsel indicated that the claim terminology in                 
          question clearly was intended to cover direct measurement of                
          both density and pressure.                                                  


          Given the conflicting positions set forth in appellant's                    
          reply brief and at the oral hearing on July 11, 2000, we are                
          at a loss to clearly understand what the scope and content of               
          claims 35 through 37 on appeal are intended to be and exactly               
          what measurements are to be excluded by appellant's use of the              
          terminology "parameters determinative of" in the measuring                  
          step and "consisting essentially of" in the estimating step of              

                                          6
