          Appeal No. 1998-2083                                                        
          Application No. 08/471,584                                                  


          78 through 81 are not indefinite because the expressions “the               
          lowered position” and “the raised position” find clear                      
          antecedent basis in lines 13-15 of claim 78 and refer to the                
          positions of the horizontal arms 233, 234.  We agree.                       
               Since the metes and bounds of claims 78 through 81 are                 
          set forth with a reasonable degree of precision and                         
          particularity,                                                              
          the decision of the examiner to reject claims 78 through 81                 
          under 35 U.S.C. § 112, second paragraph, is reversed.                       
          The obviousness issues                                                      


               Upon evaluation of all the evidence before us, it is our               
          conclusion that the evidence adduced by the examiner is                     
          insufficient to establish a prima facie case of obviousness                 
          with respect to the claims under appeal.  Accordingly, we will              
          not sustain the examiner's rejection of claims 17 and 75                    
          through 80 under 35 U.S.C. § 103.                                           
               In rejecting claims under 35 U.S.C. § 103, the examiner                
          bears the initial burden of presenting a prima facie case of                
          obviousness.  See In re Rijckaert, 9 F.3d 1531, 1532, 28
