              Application 10/219,135                                                                                          

          1           Claim 1 reproduced below, is further illustrative of the claimed subject                                
          2   matter:                                                                                                         
          3                  1.  A reversible ratcheting wrench pawl, the pawl comprising a rigid                             
          4           body having a side with a plurality of teeth, said plurality of teeth including                         
          5           a first teeth portion having a first center of curvature and a second teeth                             
          6           portion having a second center of curvature located at a position different                             
          7           from the first center of curvature, wherein the pawl has a first ratcheting                             
          8           position, wherein the first teeth portion is completely engaged with a gear                             
          9           wheel and the second teeth portion is disengaged with the gear wheel, and a                             
         10           second ratcheting position wherein the second teeth portion is completely                               
         11           engaged with the gear wheel and the first teeth portion is disengaged with                              
         12           the gear wheel, wherein the pawl moves between the first ratcheting                                     
         13           position and the second ratcheting position by rotating about an axis that                              
         14           does not intersect said rigid body.                                                                     
         15                                                                                                                   
         16           The reference of record relied upon by the Examiner as evidence of                                      
         17   anticipation is:                                                                                                
         18           Hsieh                       US 6,044,731                        Apr. 4, 2000                          
         19                                                                                                                   
         20           Claims 1, 2, 4-10, 12-14, 20-39, and 41-55 stand rejected under 35 U.S.C. §                             
         21   102 as anticipated by Hsieh.                                                                                    
         22           According to the Appeal Brief, the claims stand or fall as a single group.                              
         23   Therefore all claims on appeal will stand or fall with claim 1.                                                 
         24                                               ISSUE                                                               
         25           The sole issue for our consideration on appeal is whether claim 1 lacks                                 
         26   novelty over the Hsieh reference.                                                                               
         27                                       FINDINGS OF FACT                                                            
         28           It is our finding that Hsieh discloses a double reversible ratcheting wrench                            
         29   which has a pawl or stop block 3.  The stop block 3 has two teeth portions 31, 31                               
         30   that interact with the drive member 2.  The argued difference for appeal is whether                             
         31   the two teeth portions 31 on the pawl 3 of Hsieh have centers of curvature differing                            

                                                              2
