          Appeal No. 1999-0231                                                        
          Application No. 08/472,354                                                  

          pressure region.2                                                           
               In construing the language “means extending axially                    
          across a length of the blanket cylinder circumferential                     
          surface,” we note that the “means” may comprise, for example,               
          a groove 50 as shown in Figure 3.  The groove 50 is described               
          in the specification (pp. 7, 8) as “extending straight across               
          the circumferential surface of the blanket cylinder” and as                 
          connecting the interface of the blanket cylinder 40 and a                   
          printing blanket mounted thereon to an air canal 60.                        
               We also note the appellants’ argument on page 5 of the                 
          brief that the circumferential grooves 10b in the embodiment                
          illustrated in Figure 1 of Fellows do not meet the claimed                  
          means limitation because the grooves 10b in Fellows would only              
          allow air trapped between the blanket and cylinder at the                   
          circumferential grooves to escape.  In fact, Fellows teaches                
          that the grooves 10b in Figure 1 are 6 mm wide (col. 2, l. 67)              
          and “typically located 25 mms from the ends of the tube 10 and              
          at about 30 cms spacing along the length of the tube 10" (col.              

               According to the appellants’ specification (p. 8), the ”low pressure2                                                                     
          region” may be the atmosphere.
