          Appeal No. 95-2788                                                          
          Application 08/038,430                                                      

                    cartridge.  In the absence of an upper                            
                    limit, the composition includes values                            
                    approaching and including 100%.                                   
                    Accordingly, the specification is non-                            
                    enabling as to a data storage cartridge                           
                    having a composition of PTFE or carbon                            
                    fiber as large as that encompassed by                             
                    the limitations "at least 15%" and "at                            
                    least 30%".                                                       
                    We presume that the rejection directed to "at least               
          15%" and "at least 30%" still stands, even though the examiner              
          says nothing about appellants' arguments directed thereto, since            
          the examiner states, at page 3 of the answer, that the rejection            
          "is set forth in the prior Office action paper number 11,                   
          paragraph nos. 2 and 3."                                                    
                    We will not sustain the rejection of claims 21 through            
          39 under the first paragraph of 35 U.S.C. 112 because it is our             
          view that the examiner has not established a reasonable basis for           
          challenging the sufficiency of the instant disclosure.                      
                    We point to appellants' arguments at pages 9-13 of the            
          brief and adopt such as our own in reversing the rejection before           
          us.  In addition, we make the following amplifying comments.                
                    The examiner does not question that there are disclosed           
          and enabling embodiments for the claimed ranges.  The examiner's            
          problem appears to stem from the fact that the examiner can                 
          envision values within the claimed ranges which probably could              


                                         -4-
