          Appeal No. 95-4530                                                          
          Application 08/077,993                                                      


          that has been objected to before as not being enabled in the                
          specification and that claims 11, 12 and 14-16 are rejected under           
          35 U.S.C. § 112, first paragraph, for the reasons set forth in              
          the objection to the specification.  The examiner's previous                
          rejection indicated, inter alia, that the specification is                  
          objected to under 35 U.S.C. § 112, first paragraph, as failing to           
          provide an enabling disclosure for the circuitry capable of                 



          performing the function of the silence distinction circuit                  
          recited in claim 17 (Paper No. 7, page 3).  We reverse the                  
          rejection.                                                                  
               The examiner has provided no more than the observation that            
          appellant has failed to provide specific circuitry for the                  
          distinction circuit and the conclusion that this failure renders            
          the specification non-enabling with respect to the above claims.            
          However, patents are often granted to applicants where the                  
          details of apparatus for performing known electronic functions              
          are not disclosed.  Such apparatus includes counters and                    
          comparators, even central processing units (CPU's).  Patents are            
          not production documents.  Here, it was incumbent on the examiner           
          to set forth a reasonable basis to conclude that one skilled in             

                                          6
