          Appeal No. 95-3512                                                          
          Application 08/092,540                                                      


          least one of said waistband portions . . . to present a soft                
          surface at said inside of the diaper waistband despite the                  
          plastic material at the edge of the body portion.”  Claim 41                
          calls for the waist band to include “plastic material at border             
          edges thereof” and “a padding member extending along an opposite            
          edge portion at an exposed surface of the waist band . . .                  
          including at least one strip of material formed from a soft                 
          substance . . . forming a soft surface for contact with the skin            
          of the individual at least one of the border edges.”                        
               As indicated above, the examiner concedes that the Gilles              
          diaper does not meet the noted limitations in claims 26, 34 and             
          41 relating to the plastic layer or material.  In this regard,              
          the Gilles diaper is made essentially of cloth fabric and is not            
          disclosed as containing any plastic layer or material of the sort           
          required by the claims.  The examiner’s conclusion that it would            
          have been an obvious matter of design choice to provide the                 
          Gilles diaper with such a plastic layer or material is not well             
          founded.                                                                    
               Rejections based on 35 U.S.C. § 103 must rest on a factual             
          basis.  In re Warner, 379 F.2d 1011, 1017, 154 USPQ 173, 177-78             
          (CCPA 1967).  In making such a rejection, the examiner has the              
          initial duty of supplying the requisite factual basis and may               

                                          6
