            Application 08/574,544                                                                       


            35 U.S.C.  102(b) as being anticipated by Lewis, and                                        
            appealed claim 5 stands rejected under 35 U.S.C.  103 as                                    
            being unpatentable over Lewis.  Appealed claim 5                                             
            additionally stands rejected under 35 U.S.C.  112, second                                   
            paragraph, as being indefinite for failing to particularly                                   
            point out and distinctly claim the subject matter which                                      
            appellants regard as their invention.                                                        
                  Considering first the  102(b) rejection of claim 6,                                   
            Lewis discloses an artificial leg having a thigh section A                                   
            and a lower leg portion D attached to the thigh section by a                                 
            pair of strap assemblies.  Each strap assembly in Lewis’                                     
            artificial leg has pivotally interconnected upper and lower                                  
            metal straps E and F to allow pivotal movement between the                                   
            thigh section and the lower leg portion.  The upper straps E                                 
            of the two strap assemblies are fastened to the thigh                                        
            section.  The lower straps F of the strap assemblies are                                     
            attached to the lower leg portion.  Contrary to appellants’                                  
            arguments, the lower straps F are considered to be embedded                                  
            in the lower leg portion in that they appear from the                                        
            showing in Figure 1 of Lewis’ drawings to be received in                                     
            upwardly opening pockets in the lower leg portion.                                           

                                                  4
