          Application No. 08/807,780                                                  


               Claims are considered to be definite, as required by the               
          second paragraph of 35 U.S.C. § 112, when they define the                   
          metes and bounds of a claimed invention with a reasonable                   
          degree of precision and particularity.  See In re Venezia, 530              
          F.2d 956, 958, 189 USPQ 149, 151 (CCPA 1976).  Thus, if the                 
          scope of a claim would be reasonably ascertainable by those                 
          skilled in the art, then the claim is not indefinite.  See Ex               
          parte Porter, 25 USPQ2d 1144, 1146 (Bd. Pat. App. & Int.                    
          1992).                                                                      


               With this as background, we turn to the specific                       
          rejection of claim 11 under 35 U.S.C. § 112, second paragraph,              
          made by the examiner.  As set forth in the answer (pp. 7-8),                
          the examiner determined claim 11 to be indefinite since it was              
          "unclear what structure is being referred to as the 'noise                  
          maker' which is inside the housing."  The examiner questioned               
          whether the noise maker was a separate structure from the                   
          material of the main housing.  If so, the examiner stated that              
          "this would contradict claim 1."
