          Appeal No. 2002-0792                                                        
          Application 08/801,646                                                      


               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               
          these principles in mind, we commence review of the pertinent               
          evidence and arguments of Appellants and Examiner.                          
               Appellants argue that for claims 1, 19 and 23, the Examiner            
          has failed to show that Polychronopoulos teaches a shared arena             
          within the memory, wherein the shared arena includes a register             
          save area for each of the plurality of threads.  Appellants also            
          argue that neither Anderson nor Polychronopoulos teaches a shared           
          arena including a register save area for a plurality of threads             
          or reading register context associated with a selected thread of            
          plurality of register save areas as recited in Appellants’ claims           
          1, 19 and 23.  See page 8 of Appellants’
