               Appeal 2007-1938                                                                             
               Application 10/050,437                                                                       
                      essentially maintains contact of the polymers at their interface"                     
                      (Specification ¶¶ 13 and 16).                                                         
                 [11] The specification does not define the claim term "monolithic."                        
                 [12] Table 1 is said to show data for composites of carbon aerogel and (a)                 
                      phenolic resin foam, (b) resorcinol resin foam and (c) furan foam                     
                      (Specification 6:1).                                                                  
                 [13] Table 1 does not show any porosity data for the three carbon aerosol-                 
                      foam composites which are said to have densities of (a) 125, (b) 124                  
                      and (c) 115 kg/m3, respectively (Specification 6, Table 1).                           
                      B.    Droege                                                                          
                 [14] Droege describes a method of forming an aerogel/carbon substrate                      
                      composite comprising infusing a porous carbon substrate with a                        
                      mixture of carbon aerogel precurors, allowing the infused porous                      
                      carbon substrate to form a gel/porous substrate composite, curing the                 
                      gel/porous substrate composite, drying the cured gel/carbon substrate                 
                      composite and pyrolyzing the dried gel/carbon substrate composite                     
                      (Droege col. 2, ll. 15-20; col. 7, ll. 18-20; col. 14, ll. 15-65).                    
                 [15] The carbon aerogel precursors comprise an aqueous solution of                         
                      resorcinol ("R"), formaldehyde and a sodium carbonate catalyst ("C")                  
                      having a molar concentration R/C value of greater than about 1000                     
                      (Droege col. 4, ll. 24-30; col. 5, ll. 1-5; col. 6, l. 65 - col. 7, l. 5; col.        
                      14, ll. 25-31).                                                                       
                 [16] The porous carbon substrate may take a variety of forms, including                    
                      fibers and reticulated foams (Droege col. 14, ll. 49-65).
