               Appeal No. 2006-2004                                                                                               
               Application 10/022,823                                                                                             

                      We refer to the answer and to the brief and reply brief for a complete exposition of the                    
               positions advanced by the examiner and appellants.                                                                 
                                                            Opinion                                                               
                      The principal issue in this appeal involves the product-by-process claim language of                        
               independent claim 16 specifying that any cellulosic material contained by any manner of textile                    
               material is “treated” in any manner with any amount of any polyvinylamine and any amount of a                      
               complexing agent such that some amount of complexing agent bonds some amount of                                    
               polyvinylamine to the cellulosic material.  Dependent claim 24 further modifies claim 16 by                        
               requiring the textile material to further contain nitrogen containing natural or synthetic fibers.                 
               See, e.g., In re Am. Acad. of Sci. Tech. Ctr., 367 F.3d 1359, 1364, 70 USPQ2d 1827, 1830 (Fed.                     
               Cir. 2004); In re Morris, 127 F.3d 1048, 1054-55, 44 USPQ2d 1023, 1027 (Fed. Cir. 1997); In re                     
               Zletz, 893 F.2d 319, 321-22, 13 USPQ2d 1320, 1322 (Fed. Cir. 1989).                                                
                      In order to establish a prima facie case of obviousness of claims 16 and 24 under                           
               § 103(a), the examiner must show that some objective teaching, suggestion or motivation in the                     
               applied prior art taken as a whole and/or knowledge generally available to one of ordinary skill                   
               in this art would have led that person to the claimed invention as a whole, including each and                     
               every limitation of the claim arranged as required by the claims, without recourse to the                          
               teachings in appellants’ disclosure.  See generally, In re Kahn, 441 F.3d 977, 985-88, 78                          
               USPQ2d 1329, 1334-37 (Fed. Cir. 2006); In re Lee, 277 F.3d 1338, 1343, 61 USPQ2d 1430,                             
               1433-34 (Fed. Cir. 2002); In re Rouffet, 149 F.3d 1350, 1358, 47 USPQ2d 1453, 1458 (Fed. Cir.                      
               1998); Pro-Mold and Tool Co. v. Great Lakes Plastics, Inc., 75 F.3d 1568, 1573, 37 USPQ2d                          
               1626, 1629-30 (Fed. Cir. 1996); In re Fritch, 972 F.2d 1260, 1265-66, 23 USPQ2d 1780, 1783-                        
               84 (Fed. Cir. 1992);   In re Fine, 837 F.2d 1071, 1074-76, 5 USPQ2d 1596, 1598-1600 (Fed. Cir.                     
               1988); In re         Dow Chem. Co., 837 F.2d 469, 473, 5 USPQ2d 1529, 1531 (Fed. Cir. 1988).                       
                      The principal issues raised in these grounds of rejection are whether one of ordinary skill                 
               in this art would have found in the combined teachings of Schrell with Evani and with Geer the                     
               suggestion to treat the textile fibers of Schrell, which contain an occluded polyvinylamine, with                  
               the pH sensitive binders of Evani and with the polymers of Geer in the reasonable expectation of                   
               enhancing the strength of the fibers of Schrell, and in such manner as to further reasonably                       
               appear to bond the polyvinylamine contained by the fibers of Schrell to the cellulosic material of                 

                                                              - 3 -
