         Appeal No. 2003-1038                                                       
         Application No. 09/262,628                                                 

         2001, paper 10, appendix.)  These amended claims are now on                
         appeal.                                                                    
              The examiner’s basic position is that the specification               
         (including the claims), as originally filed, lacks adequate                
         support for the invention as is now recited in the appealed                
         claims.  Specifically, the examiner finds that while the                   
         originally filed specification describes a broad genus of                  
         polymers that may encompass “fluoroplastics,” it does not                  
         contain sufficient descriptive support for subject matter                  
         restricted to orthodontic articles comprising a “fluoroplastic.”           
              The appellants, on the other hand, argue that the                     
         “Background of the Invention” as well as a particular disclosure           
         in Grootaert ’002 provide evidence that all of the fluoropolymer           
         species described in the originally-filed specification are in             
         fact “fluoroplastics” and that, therefore, a person having                 
         ordinary skill in the art would have appreciated upon reading              
         the specification that the appellants, at the time of filing,              
         had possession of the invention now claimed.  (Appeal brief,               
         pages 8-9.)                                                                
              We cannot agree with the appellants on this issue.                    
              While the appellants are correct in stating that an                   
         applicant does not have to describe exactly the subject matter             
         claimed to satisfy the written description requirement of 35
