          Appeal No. 2003-1725                                                        
          Application No. 09/357,645                                 Page 8           

               Here, the examiner has not fairly established that the                 
          recitations referred to result in a violation of the definiteness           
          requirements of § 112, second paragraph for substantially the               
          reasons as stated by appellants (substitute brief, pages 13-16.             
          In that regard, we note that the examiner has the burden of                 
          presenting a prima facie case of indefiniteness.  This, the                 
          examiner has not accomplished with the questions and conclusions            
          presented.  Those comments merely suggest that the examiner                 
          questions the claim meaning without providing the requisite                 
          detailed analysis establishing that the metes and bounds of the             
          so rejected claims are not ascertainable.                                   
                               Alleged Relative Terms                                 
               The examiner opines that the terms, “essentially non-                  
          compliant,” “essentially perpendicular” and “substantially                  
          linear” are indefinite.  It is apparently the examiner’s view               
          that the use of such terms without the provision of a standard or           
          definition for those terms in the specification results in claims           
          of unascertainable scope, especially in light of alleged “ill-              
          defined forces” in combination with those terms.                            
               We do not subscribe to the examiner’s viewpoint.  Here, the            
          examiner has not fairly carried the burden of establishing that             
          the claim language, as it would have been interpreted by one of
