          established using hindsight or in view of the teachings or                  
          suggestions of the inventor.”  Para-Ordnance Mfg. Inc. v. SGS               
          Importers Int’l Inc., 73 F.3d 1085, 1087, 37 USPQ2d 1237, 1239              
          (Fed. Cir. 1995), cert. denied, 519 U.S. 822 (1996)(citing                  
          W.L. Gore & Assocs., Inc. v. Garlock, Inc., 721 F.2d 1540,                  
          1551, 1553, 220 USPQ 303, 311, 312-13 (Fed. Cir. 1983), cert.               
          denied, 469 U.S. 851 (1984)).  “It is impermissible to use the              
          claimed invention as an instruction manual or ‘template’ to                 
          piece together the teachings of the prior art so that the                   
          claimed invention is rendered obvious.”                                     
          In re Fritch, 972 F.2d 1260, 1266, 23 USPQ2d 1780, 1784 (Fed.

          1885, 1888 (Fed. Cir. 1991)).  “The mere fact that the prior                
          art may be modified in the manner suggested by the Examiner                 
          does not make the modification obvious unless the prior art                 
          suggested the desirability of the modification.”  Id. at 1266,              
          23 USPQ2d at 1784 (citing In re Gordon, 733 F.2d 900, 902, 221
