          Appeal No. 96-3950                                                          
          Application No. 08/131,056                                                  


               We further note that Appellants argue that In re                       
          Donaldson Co. Inc., 16 F. 3d 1189, 1193, 29 USPQ2d 1845, 1848               
          (Fed. Cir. 1994) requires that the "means for" language                     
          occurring in the claims, in accordance with 35 U.S.C. § 112,                
          sixth paragraph, must be interpreted as covering the                        
          structure, material or acts set forth in the specification and              
          equivalents thereof.  However, while Appellants have pointed                
          to corresponding structure within their specification for the               
          means statements in the claims, from our earlier discussion we              
          are not persuaded that the structure disclosed by Dennis would              
          not be considered equivalent.                                               
               With respect to claims 2-6, Appellants have argued at                  
          page 5 of the Reply Brief that the Examiner has improperly                  
          addressed only claim 1 in the rejection.  While Appellants are              
          correct to the extent that the Examiner has treated claim 1 as              
          an exemplary claim, it is our view that the Examiner's                      
          analysis in the Answer establishes a prima facie case of                    
          anticipation with regard to claims 2-4 and 6 as well.  We                   
          agree with the Examiner that in the "option 1" mode of Dennis               
          the host produces compressed data as recited in claim 2, the                
          rasterization is performed solely in the host computer as                   
                                          12
