          Appeal No. 1997-1304                                                        
          Application 08/084,345                                                      

          to the claimed invention of representative claim 1, for                     
          example, on appeal.                                                         
               For appellant's part, we generally agree with the                      
          appellant's characterization of this reference to Yan in the                
          principal brief on appeal where appellant makes reference at                
          page 11 of this brief to the earlier noted conflicting                      
          positions of the examiner as to the feature of generating                   
          linear combinations of placement vectors.                                   
               We conclude the examiner has not set forth a prima facie               
          case of obviousness of the claimed invention in light of the                
          collective teachings of the two references relied upon because              
          of the above noted weaknesses in the examiner's position as to              
          Yan and the fact that the examiner does not attempt to                      
          correlate the individual features of representative                         
          independent claim 1 on appeal, for example, to the teachings                
          and showings in Weyl.  There is no explicit teaching in this                
          reference of placement vectors per se, let alone a linear                   
          combination of them in the manner claimed.  There is, however,              
          in Weyl an apparent historical development of a mathematical                
          basis of vector algebra as applied to images that are                       
          effectively duplicated or translated from one position to
