          Appeal No. 97-3708                                                          
          Application 08/418,321                                                      


          found it obvious to use a flat form of the type disclosed by                
          Stockum in the method for forming the sturdy three dimensional              
          boot of Marx, absent the hindsight accorded one who first                   
          viewed appellants’ disclosure.  Such hindsight reconstruction,              
          of course, is not a proper basis for establishing the                       
          obviousness of the subject matter of claims.  See In re                     
          Fritch, 972 F.2d 1260, 1266, 23 USPQ2d 1780, 1784 (Fed. Cir.                
          1992).  We therefore will not sustain the standing § 103                    
          rejection of the appealed claims as being unpatentable over                 
          Marx, Stockum and Bodle.                                                    
               Under the provisions of 37 CFR § 1.196(b), we enter the                
          following new rejection.                                                    
               Claim 18 is rejected under 35 U.S.C. § 112, second                     
          paragraph, for failing to particularly point out and                        
          distinctly claim the subject matter sought to be patented.                  
          This claim is                                                               




          directed to a method of forming a shoe cover, and recites a                 
          number of steps (providing a form, dipping the form into                    


                                          -8-
