               Appeal 2007-2888                                                                             
               Application 11/017,602                                                                       
                      Appellant asserts that “Sloan simply cannot be an interference fit                    
               otherwise such an interference fit would prevent moisture condensing within                  
               the bag 36 [an insulating element] from communicating out of the bag                         
               through the outlet aperture 44” (Reply Br. 2; see also Appeal Br. 7-8).                      
                      We do not find this argument persuasive.  Sloan describes “apertures”                 
               connected to flow ducts that lead to the exterior space (FF 5-6).  As shown                  
               in Fig. 8 of Sloan (FF 6), the elements are arranged in a vertical series with               
               each connected to another. Fluid flows vertically through the bag, through                   
               the aperture, and into the next bag (FF 5-6).  The interference fit between the              
               lateral frame members would not obstruct the water because the water flows                   
               through the bag and out the aperture at its bottom (as shown in the                          
               embodiment of Fig. 8).                                                                       
                      For the foregoing reasons, we affirm the rejection of claims 1 and 17.                
               Claims 2 and 18 were not separately argued; consequently, they fall with                     
               claims 1 and 17.  See C.F.R. 41.37(c)(1)(vii).                                               
                                                                                                           
                                             OBVIOUSNESS                                                    
                      Claims 3-5 and 7-16 stand rejected under 35 U.S.C. § 103(a) as                        
               obvious over Sloan in view of Yoerkie or Allen.                                              

                                             Issues on Appeal                                               
                      The issues in this rejection are whether the skilled person would have                
               had reason to have further provided the foam portion with a) a mass barrier,                 
               b) a mass barrier with a barium sulfate, and c) to have attached the mass                    
               barrier to the foam and to the frame members.
