          Appeal No. 2003-1873                                                        
          Application 09/281,420                                                      

          forward with evidence or argument shift to the Appellants.                  
          Oetiker, 977 F.2d at 1445, 24 USPQ2d at 1444.  See also Piasecki,           
          745 F.2d at 1472, 223 USPQ at 788.                                          

            An obviousness analysis commences with a review and                       
          consideration of all the pertinent evidence and arguments.  “In             
          reviewing the [E]xaminer’s decision on appeal, the Board must               
          necessarily weigh all of the evidence and argument.”  Oetiker,              
          977 F.2d at 1445, 24 USPQ2d at 1444.  “[T]he Board must not only            
          assure that the requisite findings are made, based on evidence of           
          record, but must also explain the reasoning by which the findings           
          are deemed to support the agency’s conclusion.”  In re Lee, 277             
          F.3d 1338, 1344, 61 USPQ2d 1430, 1434 (Fed. Cir. 2002).                     

            With respect to independent claim 24, Appellants argue the                
          references do not describe “a distributed network environment,              
          nor the existence of multiple clients within such an environment,           
          nor the distribution of a query request from a root node to                 
          multiple clients within a distributed network environment, nor              
          the receiving back or responses at a root node.”  (Appellants’              
          brief at pages 8-10).
