          Appeal No. 97-1163                                                          
          Application 08/200,044                                                      

               The rejection of claims 1, 3-7, and 9-14 under 35 U.S.C.               
          § 112, first paragraph, is summarily reversed.  The examiner                
          has not made any showing of why the specification is either                 
          (1) without an enabling disclosure for the claimed invention,               
          (2) without an adequate written description of the claimed                  
          invention, or (3) fails to disclose the best mode as                        
          contemplated by the inventors.                                              
               Evidently, the real rejection is under 35 U.S.C. § 112,                
          second paragraph, for being vague and indefiniteness, which we              
          also cannot sustain.                                                        
               It is not the role of claims to explain how the invention              
          works or how it may be constructed and made to operate.  That               
          is the purpose of the specification.  The claims merely define              
          the metes and bounds or the scope of coverage of the invention              
          sought to be protected.  In our view, the claims clearly                    
          define, in no uncertain terms, what is within their scope and               
          what is not.  While the claims are indeed broad, breadth of                 
          claim should not be confused with indefiniteness.  In re                    
          Miller, 441 F.2d 689, 693, 169 USPQ 597, 600 (CCPA 1971); In                
          re Gardner, 427 F.2d 786, 788, 166 USPQ 138, 140 (CCPA 1970).
