          Appeal No. 2003-1725                                                        
          Application No. 09/357,645                                 Page 9           

          ordinary skill in the art in light of appellants’ specification             
          and the prior art would have been indefinite within the meaning             
          of § 112, second paragraph.  In this regard and for reasons                 
          stated above and in the briefs, we do not find that the claims              
          include ill-defined forces as alleged by the examiner.  Thus, to            
          the extent that the examiner is relying on alleged ill-defined              
          forces to buttress the examiner’s position, such reliance is not            
          persuasive.  Moreover, appellants have furnished detailed                   
          arguments and references to their specification (supplemental               
          brief, pages 15-20) explaining why one of ordinary skill in the             
          art would have been reasonably apprised of the claim scope.  The            
          examiner’s conclusary comment at page 13 of the answer does not             
          serve to rebut those arguments.  The examiner simply has not                
          satisfactorily explained why one of ordinary skill in the art               
          would not find those “relative” terms reasonably precise as they            
          relate to the properties of the occluding member, the                       
          construction and positioning of the force actuator relative to              
          the occluding member and the orientation of the occluding member            
          relative to the wall of a tube to be occluded.  Certainly, the              
          examiner has not furnished any evidence indicating that more                
          precision than the language employed in the claims is necessary             
          to particularly point out and distinctly claim the subject matter
