          Appeal No. 1996-1736                                                        
          Application 08/418,267                                                      


          unpatentable over appellant’s admitted prior art in view of                 
          Sasaoka, Wooton and Adams.                                                  
               Reference is made to the brief and the answer for the                  
          respective positions of the appellant and the examiner.                     
                                       OPINION                                        
               The obviousness rejetion of claim 17 is reversed.                      
               It is acknowledged in appellant’s admitted prior art that              
          “[p]ositive and negative high voltages are applied to separate              
          electrodes,” and that “[d]ispersal of the ions is usually                   
          accelerated by directing an airflow through the electrode                   
          region and out into the room” (Specification, page 2).                      
               Sasaoka discloses (Figures 1 and 2) that it is known to                
          configure an electronic air cleaner so that an ion generating               
          source is located between the air inlet and the fan.  The air               
          outlet is located on the other side of the fan.                             
               In Wooton, all of the different embodiments (Figures 2                 
          through 4) only use a negative ion emitter.  In the latter                  
          embodiment (Figure 4), all of the metal whiskers 58 located                 
          around the support ring 54 emit negative ions.  The whiskers                
          do not emit positive ions.                                                  


                                          4
