          Appeal No. 2003-0882                                       Page 5           
          Application No. 09/911,198                                                  

          page 11).  Appellants assert that it is impossible to furnish a             
          programmed value to the output terminal of Jung while Q10 is                
          disabled (id.).  Appellants do not rebut any specific teaching of           
          Jung, but rather disagree with examiner’s interpretation of the             
          reference (brief, page 12).  Additionally, appellants (reply                
          brief, page 2) do not dispute examiner’s assertion of well-known            
          facts that "an inverter can be implemented using a PMOS                     
          transistor and an NMOS transistor," and that "two inverters                 
          connected in a loop constitutes a latch."  Appellants assert,               
          however, that the examiner has failed to consider other basic               
          complementary metal oxide semiconductor (CMOS) principles when              
          utilizing Jung (id.).  In Appellants’ Appendix B, appellants rely           
          on an excerpt from a textbook FUNDAMENTALS OF MOS DIGITAL                   
          INTEGRATED CIRCUITS, Figure 3.26, that discloses a basic CMOS               
          inverter circuit having a path to ground for transistor function            
          (reply brief, page 3).                                                      
               From the disclosure of the textbook, appellants conclude               
          that the pulldown transistor Q10 with the input “EN” enables and            
          disables the ability of Q5-Q8 to form inverters and thus form a             
          latch [emphasis added by appellants] (id.).  In contradiction to            
          the examiner’s assertion, appellants assert that Q5-Q8 float when
