          Appeal No. 2000-1557                                                        
          Application 08/384,456                                                      


          step including combination of the first and second demodulated              
          signals within or subsequent to the determination by the error              
          correction decoding process of the data most likely transmitted             
          [answer, page 3].  Appellants simply respond that the claimed               
          phrase is fully supported by the disclosure and original claim 6            
          [brief, page 6].  The examiner responds that the portion of the             
          disclosure relied on by appellants and original claim 6 are                 
          totally silent about the phrase in question [answer, pages 10-              
          11].                                                                        
          We agree with the position argued by the examiner.  The                     
          rejection is based on the written description requirement of                
          35 U.S.C. § 112.  The purpose of the written description                    
          requirement is to ensure that the applicants convey with                    
          reasonable clarity to those skilled in the art that they were in            
          possession of the invention as of the filing date of the                    
          application.  For the purposes of the written description                   
          requirement, the invention is "whatever is now claimed."                    
          Vas-cath, Inc. v. Mahurkar, 935 F.2d 1555, 1564, 19 USPQ2d 1111,            
          1117 (Fed. Cir. 1991).  We have considered the record, and we               
          cannot find clear support for the recitation that the error                 
          correcting step includes combination of said first and second               
          demodulated signals “within or subsequent to” the determination             
                                          5
