          Appeal No. 96-2693                                                          
          Application No. 08/018,972                                                  


               After a careful review of the evidence before us, we                   
          affirm the 35 U.S.C. § 102 and 35 U.S.C. § 103 rejections.                  
          It is axiomatic that anticipation of a claim under § 102 can                
          be found only if the prior art reference discloses every                    
          element of the claim.  See In re King, 801 F.2d 1324, 1326,                 
          231 USPQ 136, 138 (Fed. Cir. 1986) and Lindemann                            
          Maschinenfabrik GMBH v. American Hoist & Derrick Co., 730 F.2d              
          1452, 1458, 221 USPQ 481, 485 (Fed. Cir. 1984).  "Anticipation              
          is established only when a single prior art reference                       
          discloses, expressly or under principles of inherency, each                 
          and every element of a claimed invention."  RCA Corp. v.                    
          Applied Digital Data Systems, Inc.,                                         
          730 F.2d 1440, 1444, 221 USPQ 385, 388 (Fed. Cir. 1984), cert.              
          dismissed, 468 U.S. 1228 (1984), citing Kalman v. Kimberly-                 
          Clark Corp., 713 F.2d 760, 772, 218 USPQ 781, 789 (Fed. Cir.                
          1983).                                                                      
               Appellants argue on page 7 of the brief that PKZIP                     
          detects only one [hardware] attribute while Appellants' claims              
          1 and 7 claim "reading at least one hardware attribute".  As                
          pointed out by our reviewing court, we must first determine                 


                                          4
