         Appeal No. 2006-2051                                                       
         Application No. 10/396,955                                                 
              APA, Chan and Jayaraman.  Particularly, the Examiner relies           
         upon APA (drawing figures 1 and 2, specification page 5, line 27           
         through page 6, line 8 of Appellants’ written description) as a            
         primary reference to establish a prima facie case of obviousness           
         against the cited claims.                                                  
              Under current patent law, a statement by an applicant                 
         during prosecution identifying the work of another as “prior art”          
         is an admission that that work is available as prior art against           
         the claims, regardless of whether the admitted prior art would             
         otherwise qualify as prior art under the statutory categories of           
         35 U.S.C. 102. Riverwood Int ’l Corp. v. R.A. Jones & Co., 324             
         F.3d 1346, 1354, 66 USPQ2d 1331, 1337 (Fed Cir. 2003). However,            
         even if labeled as “prior art,” the work of the same inventive             
         entity may not be considered prior art against the claims unless           
         it falls under one of the statutory categories. Id.; see also              
         Reading  & Bates Construction Co. v. Baker Energy Resources                
         Corp., 748 F.2d 645, 650, 223 USPQ 1168, 1172 (Fed. Cir. 1984)             
         (“[W]here the inventor continues to improve upon his                       
              own work product, his foundational work product should not,           
         without a statutory basis, be treated as prior art solely because          
         he admits knowledge of his own work. It is common sense that an            
         inventor, regardless of an admission, has knowledge of his own             

                                         3
