                   This is a decision on appeal under 35 U.S.C. § 134 of the final rejection of claims        
            1 through 14, which constitute all the claims in the application.                                 
                                                  Invention                                                   
                   The invention relates to an event notification channel for an object oriented              
            programming system with a plurality of supplier objects and a plurality of event                  
            consumer objects.  The system uses a plurality of proxy consumer objects, each                    
            associated with one of the consumer objects, whereby the proxy consumer objects may               
            receive supplier transmitted events on behalf of the associated consumer object.  Thus            


                                                     -1-
