          Appeal No. 1999-2637                                                        
          Application 08/813,864                                                      


          Botterill nor Marisetty, alone or in combination, teaches                   
          these claimed                                                               
          limitations.  We further determine that the Ashkin prior art                
          does not close the gap by teaching or suggesting these claimed              
          limitations.                                                                
               We find that Ashkin discloses a method of transferring                 
          data between a plurality of peripheral devices and a host                   
          computer.  Ashkin, column 2, lines 35-55.  Nothing in Ashkin                
          teaches or suggests the limitation of enabling “multiple                    
          display sessions through the single address on the NPT.”                    
          Further, we find that nothing in Ashkin teaches or suggests                 
          the limitation of “only one of the multiple display sessions                
          having the focus at any one time.”  Therefore, we conclusively              
          determine that no implicit or explicit reason exists to                     
          plausibly combine the teachings of Botterill, Marisetty and                 
          Ashkin.  Accordingly, we find that the Examiner has failed to               
          establish a prima facie case of obviousness with respect to                 
          claim 7.  In so finding, we reverse the Examiner’s rejection                
          of independent claim 7 as obvious over Botterill, Marisetty                 
          and Ashkin.                                                                 


                                          12
