                Appeal 2007-4101                                                                               
                Application 09/962,972                                                                         
                The Appellants only rely on the same arguments and evidence discussed                          
                above to rebut the Examiner’s decision rejecting claim 15 under 35 U.S.C.                      
                § 103 rejection (Br. 16-17).  Therefore, based on the Factual Findings set                     
                forth in the Answer and above, we also determine that the preponderance of                     
                evidence weighs most heavily in favor of obviousness of the subject matter                     
                defined by claim 15 within the meaning of 35 U.S.C. § 103.                                     
                      As evidence of obviousness of the subject matter defined by claim 27                     
                under 35 U.S.C. § 103(a), the Examiner has relied on the combined                              
                disclosure of Klabunde and either the admitted prior art or Blaney.                            
                According to the Examiner (Answer 5-6):                                                        

                      Klabunde discloses the claimed invention with the exception of                           
                      the recited semipermeable container.  Applicant has admitted                             
                      (see page 13, lines 15-17 and 23-24, of the specification) that it                       
                      is known to place granulated treatment materials in                                      
                      semipermeable bags.  Blaney also teaches placing granulated                              
                      treatment materials in semipermeable bags (see Figs. 3 & 4; and                          
                      col. 6, lines 8-12).  It would have been obvious to one of                               
                      ordinary skill in the art at the time the invention was made to                          
                      provide the fluid treatment system of Klabunde with either the                           
                      admittedly known semipermeable container, or the                                         
                      semipermeable container disclosed by Blaney, in order to                                 
                      facilitate handling of the treatment material in this primary                            
                      reference system.                                                                        
                The Appellants only rely on the same arguments and evidence discussed                          
                above to rebut this rejection (Br. 16-17).                                                     
                      Accordingly, based on the Factual Findings set forth in the Answer                       
                and above, we determine that the preponderance of evidence weighs most                         
                heavily in favor of obviousness of the subject matter defined by claim 27                      
                within the meaning of 35 U.S.C. § 103.                                                         


                                                      15
