          Appeal No. 95-5061                                                          
          Application 07/825,979                                                      


          modeling to the extent claimed.  The Examiner argues that                   
          Appellants' specification on page 11, lines 9-10, defines a                 
          computer system model as a "software module, a subprogram."  The            
          Examiner argues that by this definition Luke teach tasks and                
          subtasks which meets Appellants' claimed "model".                           


               Our reviewing court states in In re Zletz, 893 F.2d 319,               
          321, 13 USPQ2d 1320, 1322 (Fed. Cir. 1989) that "claims must be             
          interpreted as broadly as their terms reasonably allow."                    
          Moreover, when interpreting a claim, words of the claim are                 
          generally given their ordinary and accustomed meaning, unless it            
          appears from the specification or the file history that they were           
          used differently by the inventor. Carroll Touch, Inc. v. Electro            
          Mechanical Sys., Inc. 15 F.3d 1573, 1577, 27 USPQ2d 1836, 1840              
          (Fed. Cir. 1993).  Although an inventor is indeed free to define            
          the specific terms used to describe his or her invention, this              
          must be done with reasonable clarity, deliberateness, and                   
          precision.  In re Paulsen 30 F.3d 1475, 1480, 31 USPQ2d 1671,               
          1674 (Fed. Cir. 1994).                                                      
               Appellants argue on pages 3 and of the reply brief that                
          Appellants' specification on page 11, lines 9 and 10 does not               
          define a model but defines a node which is part of a larger                 
                                          5
