          Appeal No. 2004-1481                                                        
          Application No. 09/726,659                                                  


          art.  See In re Buchner, 929 F.2d 660, 661, 18 USPQ2d 1331, 1332            
          (Fed. Cir. 1991).  From the teachings of Neoh, backing plates were          
          well known in this art.  Finally, as noted by the examiner (Answer,         
          page 4), original Figures 1-3 are schematic drawings and are silent         
          as to whether a backing plate is included or excluded.                      
               For the foregoing reasons and those stated in the Answer, we           
          determine that appellant has not conveyed with reasonable clarity           
          to those skilled in this art that, as of the date of this                   
          invention, appellant was in possession of the invention as now              
          claimed.  Accordingly, we affirm the examiner’s rejection of claims         
          10, 13, 14, 17 and 18 under 35 U.S.C. § 112, ¶1, for failure to             
          fulfill the “written description” requirement.                              
               B.  The Rejection under § 102(b)                                       
               The examiner finds that Neoh discloses a system capable of             
          delivering SOG comprising a tube capable of delivering SOG                  
          connected to a tool capable of using SOG and a capacitive sensor            
          mounted on the tube that is capable of detecting bubbles in the SOG         
          flowing through said tube (Answer, page 4, italics added).  The             
          examiner’s position is that the recitation of the intended use of           
          the claimed invention does not result in a structural difference            
          between the claimed invention and the prior art (Neoh)(Answer, page         


                                          6
