            Application No. 09/589,434                                                                        


                   Reading "compact flash expansion slot" and "compact flash expansion card" in               
            light of the specification, claims 1 and 18 require an expansion slot and an expansion            
            slot, respectively, that complies with the industry standard CF+ types I or II slot defined       
            by the compact flash CF+ specification maintained by the Compact Flash Association of             
            Palo Alto, California.  Claim 8 requires an expansion slot and an expansion card that             
            both comply with the industry standard CF+ types I or II slot defined by the same                 
            specification of the same Association.                                                            
                                                                                                             
                              2. ANTICIPATION AND OBVIOUSNESS DETERMINATIONS                                  
                   "Having construed the claim limitations at issue, we now compare the claims to             
            the prior art to determine if the prior art anticipates those claims."  In re Cruciferous         
            Sprout Litig., 301 F.3d 1343, 1349, 64 USPQ2d 1202, 1206 (Fed. Cir. 2002).  "To                   
            establish inherency, the extrinsic evidence 'must make clear that the missing descriptive         
            matter is necessarily present in the thing described in the reference, and that it would          
            be so recognized by persons of ordinary skill.'"  In re Robertson, 169 F.3d 743, 745, 49          
            USPQ2d 1949, 1950-51 (Fed. Cir. 1999) (quoting Continental Can Co. v. Monsanto                    
            Co., 948 F.2d 1264, 1268, 20 USPQ2d 1746, 1749 (Fed. Cir. 1991))  "Inherency . . .                
            may not be established by probabilities or possibilities.  The mere fact that a certain           
            thing may result from a given set of circumstances is not sufficient."  In re Oelrich, 666
