          Appeal No. 2001-0220                                                        
          Application No. 09/244,044                                                  

          the Answer finds no discussion of how Schmidt describes, within             
          the meaning of § 102, the claim limitation concerning the                   
          location of the holes from the bottom of the dam.  For the same             
          reason, we will not sustain the examiner's § 102 rejection of               
          claims 30 and 31 over each of Soofi '175 and Soofi '667.                    
               We will sustain the examiner's rejection of claim 32 under             
          § 103 over each of Soofi '667, Soofi '175 and Schmidt.  Although            
          the examiner recognizes that none of the cited references                   
          discloses the claimed "first and second mounting hooks that are             
          cast into said dam during its manufacture," the examiner has                
          taken official notice that it was "a well known expedient to                
          employ cast in place mounting means in refractory components in             
          order to allow fore [sic, for] easier movement by crane into                
          place" (page 4 of Answer, second paragraph).  On the other hand,            
          appellant has not challenged the correctness of the examiner's              
          assertion and has not responded to the examiner's statement that            
          "[a] statement by the applicant that this is not an expedient               
          commonly known in the art . . . would overcome this rejection"              
          (page 6 of Answer, second paragraph).  Rather, appellant has                
          simply responded that if this feature was so well known there               
          must be a reference that shows it, and that "[t]he burden is on             
          the Patent and Trademark Office to establish a prima facie case,            

                                         -6-
