          Application No. 08/810,442                                                  


               For its part, dependent claim 8 specifies in pertinent part            
          the following limitations: "the first and second computation                
          means receive neither keys nor program content from a source                
          apart from said single input."  Giving the dependent claim its              
          broadest reasonable interpretation, the limitations merely                  
          require inter alia receiving keys and program content only via              
          the single port of claim 1.                                                 
               “[H]aving ascertained exactly what subject matter is being             
          claimed, the next inquiry must be into whether such subject                 
          matter is novel.”  In re Wilder, 429 F2d 447, 450, 166 USPQ 545,            
          548 (CCPA 1970).  “[A]nticipation is a question of fact.”  Hyatt,           
          211 F.3d at 1371, 54 USPQ2d at 1667 (citing Bischoff v. Wethered,           
          76 U.S. (9 Wall.) 812, 814-15 (1869); In re Schreiber, 128 F.3d             
          1473, 1477,  44 USPQ2d 1429, 1431 (Fed. Cir. 1997).  “A claim is            
          anticipated only if each and every element as set forth in the              
          claim is found, either expressly or inherently described, in a              
          single prior art reference.”  Verdegaal Bros., Inc. v. Union Oil            
          Co., 814 F.2d 628, 631, 2 USPQ2d 1051, 1053 (Fed. Cir. 1987)                
          (citing Structural Rubber Prods. Co. v. Park Rubber Co., 749 F.2d           
          707, 715, 223 USPQ 1264, 1270 (Fed. Cir. 1984); Connell v. Sears,           
          Roebuck & Co., 722 F.2d 1542, 1548, 220 USPQ 193, 198 (Fed. Cir.
