                Appeal 2007-2127                                                                                  
                Reexamination Control No. 90/006,621                                                              
                service routine is completely separate from the compiler program and the                          
                editor does not execute any instructions in the compiler program.  This                           
                interrupt operation is illustrated by Chart 7-2 in De Jong, page 174, which is                    
                applied in one of the anticipation rejections.                                                    





















                                                                                                                 
                       For this additional reason, we find that there is no written description                   
                of "preemptive multithreading" in the 1982, 1985, or 1990 applications, and,                      
                therefore, the '604 patent is not entitled to the priority filing date of the 1982                
                application.                                                                                      


                                                       78
