          Appeal No. 1999-0960                                                        
          Application No. 08/785,437                                                  

          construction does not in our view meet the requirement of                   
          claim 1 (or of                                                              
          claim 13, the other independent claim on appeal) that the mask              
          is joined to the fold backs "along substantially an entire                  
          length of the fold backs," since in Wright the mask (screen)                
          is joined to the fold backs (edges) only at spaced points, not              
          along substantially their entire length, as claimed.                        
               The examiner also seems to believe that claim 1 is                     
          readable on Wright because "the fold backs [of Wright] are                  
          statistically bound to directly align with the wires of the                 
          protective mask at numerous locations along the surface of the              
          protective mask" (answer, page 6), noting that in Fig. 7 some               
          of Wright’s edges 4a (fold backs) coincide with the vertical                
          wires of the screen 3a.  However, even if some of Wright’s                  
          screen wires might by chance be positioned to extend along                  
          substantially an entire length of the fold backs, that would                
          not meet the recitation in claim 1 that "all the fold backs"                
          are so joined to the mask.  Likewise,                                       
          claim 13 is not readable on Wright because, although that                   
          claim does not use the word "all", we consider that,                        
          consistent with appellants’ disclosure, the claim language
