          Appeal No. 1998-2065                                                        
          Application 08/713,788                                                      


          USPQ 561, 563-64  (CCPA 1982).  In calling into question the                
          enablement of the appellant's disclosure, the examiner has the              
          initial burden of advancing acceptable reasoning inconsistent               
          with enablement.  Id.                                                       
               Although the appellants’ disclosure of a loop element                  
          having an elastic portion and a plastic portion is somewhat                 
          lacking in detail, it is not apparent, nor has the examiner                 
          cogently explained, why such disclosure would not have enabled              
          a person of ordinary skill in the art to make and use without               
          undue experimentation a garbage bag having this relatively                  
          simple and straightforward structure.  Thus, on the record                  
          before us, the appellants’ disclosure of a loop element having              
          elastic and plastic portions does not pose an enablement                    
          problem.                                                                    
               In light of the foregoing, we shall not sustain the                    
          standing 35 U.S.C. § 112, first paragraph, rejection of claims              
          6, 7 and 9 through 16.                                                      
               As for the additional 35 U.S.C. § 112, first paragraph,                
          rejection of claims 13 through 16, the examiner’s                           
          characterization of the “loop extension” limitation in claim                


                                          9
