            Appeal No. 96-1620                                                        
            Application No. 07/938,288                                                


                 We have carefully reviewed the evidence before us and,               
            based on such a review, we conclude that the claimed subject              
            matter would not have been obvious, within the meaning of                 
            35 U.S.C. ' 103, based on the evidence provided by the Durst              
            and Kurihara references.                                                  
                 With regard to claims 1 through 8, the examiner                      
            contends that Durst discloses the claimed subject matter but              
            for the data in the ROM being “microprocessor ID data,” as                
            claimed.  However, the examiner concludes that it would have              
            been obvious                                                              
                 to include a ROM for storing a microprocessor ID                     
                 data as claimed because the use of a ROM for                         
                 storing the microprocessor identification data                       
                 could help Durst to determine the authorized                         
                 software for the correct microprocessor type in                      
                 his computer system, and because Durst did suggest                   
                 the need for storing the microprocessor                              
                 identification data…in a memory [answer, pages 3-                    
                 4].                                                                  
                 We find that a careful reading of Durst suggests that,               
            at best, Durst provides for an indirect identification of a               
            processor through characteristics of the computer system                  
            such as ROM size, bus size, clock speed, etc.  However, this              
            is not a direct identification of the particular processor                
            in use in a computer system nor is the identification                     
            unique.  As pointed out by Durst, at column 16, lines 43-47,              


                 two different computer systems which otherwise                       

                                          3
