              Appeal No. 2005-2512                                                                                         
              Reexamination Control No. 90/006,431                                                                         

              it and recognize and comprehend therefrom the essentials of the claimed invention                            
              without need of further research or experimentation.”  Bruckelmyer, 445 F.3d at 1378,                        
              78 USPQ2d at 1687; Wyer, 655 F.2d at 226, 210 USPQ at 795.  As the record does not                           
              include any evidence establishing when, if ever, RailMIll Tutorial was disseminated or                       
              otherwise made available to persons skilled in the art, it has not been shown to be                          
              available as a prior-art printed publication against appellant’s claims.                                     
                     4.  Summary                                                                                           
                     None of the RailMill documents has been shown to be available as a prior-art                          
                     printed                                                                                               
              publication against appellant’s claims.                                                                      
              H.  Whether any of the subject matter in the RailMill documents, the Arcadia                                 
              Manual,                                                                                                      
              Tiwary, and Deng has been established to be the invention of Ho and Tuan                                     
                                                                                                                          
                     In the interest of completeness, this analysis assumes that the RailMill                              
                     documents have                                                                                        
              publication dates prior to appellant’s filing date, as do the Arcadia Manual, Tiwary, and                    
              Deng.                                                                                                        
                     In order to remove reference subject as prior art on the ground it represents the                     
              applicant’s own invention, the applicant (or patent owner during reexamination) must                         
              prove invention and derivation of that subject matter.  See In re Facius, 408 F.2d 1396,                     
              1407,            161 USPQ 294, 302 (CCPA 1969) (“The real question is whether, in                            
              addition to establishing derivation of the relevant disclosure from himself, appellant has
