          Appeal No. 2004-0252                                                        
          Application No. 09/439,920                                                  

          video data at column 1, lines 6-10, while the reference teaches             
          an interpolator at column 6, lines 26-39.                                   
               We will not sustain the rejection of claim 24 under                    
          35 U.S.C. § 102(e) because, in our view, the examiner simply has            
          not established a prima facie case of anticipation by merely                
          pointing to 19 lines within the disclosure of Westerman and                 
          alleging that all of the claimed subject matter is disclosed                
          therein.                                                                    
               Appellant does not argue much, but appellant does argue that           
          Westerman is devoid of the step of, or means for, “comparing said           
          image portion with said interpolation” and the examiner has not             
          convincingly shown that Westerman does, indeed, disclose this               
          subject matter.  While Westerman mentions “interpolation” and an            
          “interpolator” in the cited portions of the reference, we find no           
          suggestion, at either column 1, lines 1-5, or column 6, lines 26-           
          39, the only portions of Westerman cited by the examiner, of                
          “comparing said image-portion with said interpolation,” as                  
          required by the claim.                                                      
               The only response by the examiner, at page 10 of the answer,           
          is to assert that a subtraction step is a comparative step.  Not            
          only has the examiner not pointed to the specific portion of                
          Westerman relied on for the “subtraction step,” but, more                   

                                         -4-
