                Appeal 2006-2335                                                                               
                Application 09/851,460                                                                         

                obviousness within the meaning of 35 U.S.C. § 103(a).  See In re Oetiker,                      
                977 F.2d 1443, 1445, 24 USPQ2d 1443, 1444 (Fed. Cir. 1992).                                    
                       When considering evidence of unexpected results to rebut a prima                        
                facie case of obviousness, the burden rests with Appellants to indicate why                    
                the results are unexpected, why the comparison is with the closest prior art,                  
                and why the comparison is commensurate in scope with the subject matter                        
                sought to be patented.  See In re Mayne, 104 F.3d 1339, 1344, 41 USPQ2d                        
                1451, 1456 (Fed. Cir. 1997); In re Klosak, 455 F.2d 1077, 1080, 173 USPQ                       
                14, 16 (CCPA 1972); and Ex parte Gelles, 22 USPQ2d 1318, 1319 (Bd. Pat.                        
                App. & Int. 1992).  Although we agree with Appellants that it was                              
                impossible to keep all variables constant except one (Reply Br. 5), we                         
                determine that Appellants have not met their burden of establishing why the                    
                comparative results are commensurate in scope with the subject matter                          
                sought to be patented.  See In re Boesch, 617 F.2d 272, 276, 205 USPQ 215,                     
                219 (CCPA 1980).  All of the multilayer film laminates tested are limited to                   
                specific fillers (e.g., calcium carbonate) with specific particle sizes (e.g., 4.5             
                microns), used with specific amounts of propylene homopolymer (e.g., 47                        
                wt. %), a specific barrier layer composition, optional adhesives, and specific                 
                amounts and materials as the sealing layer (e.g., 75% polyethylene and 25%                     
                polybutylene), while the claims on appeal are not so limited.  See the                         
                Specification 8:12-27; the first Bernig Declaration, page 2, and the second                    
                Bernig Declaration, pages 1-2.  Claim 1 on appeal is not limited to any                        
                specific materials and amounts, other than the amount of “inorganic filler”                    
                and the material (polypropylene) of the filled layer.  Accordingly, we                         
                determine that Appellants have not met their burden.                                           


                                                      7
