          Appeal No. 96-1812                                                          
          Application No. 07/984,762                                                  


               In the specification (page 4) and original claim 5, a                  
          radius of curvature of “about 1 mm” is set forth.  On the                   
          other hand, the specification (page 10) also recites a radius               
          of curvature of “1 mm”.                                                     
               In our view, the recitation of “about 1 mm” is                         
          indeterminate in meaning.  The specification is silent as to                
          what the modifying word of degree “about” denotes and,                      
          therefore, the scope of the term “about 1 mm” cannot be                     
          ascertained when the term is read in light of the                           
          specification.  See Seattle Box Co. v. Industrial Crating &                 
          Packing, Inc., 731 F.2d 818, 826, 221 USPQ 568, 573-574 (Fed.               
          Cir. 1984).                                                                 


               For purposes of the following new ground of rejection                  
          under 35 USC 103, we interpret the indefinite term “about 1                 
          mm” in claims 25 and 35 as denoting --1 mm--.                               


               Claims 25 through 42 are rejected under 35 USC 103 as                  
          being unpatentable over Jessop and either Korf or the                       
          acknowledged prior art (appellants’ specification, page 1).                 


                                          7
