          Application No. 08/279,628                                                  


          modification.”  In re Fritch, 972 F.2d 1260, 1266, 23 USPQ2d                
          1780, 1784 (Fed. Cir. 1992) (citing In re Gordon, 733 F.2d                  
          900, 902, 221 USPQ 1125, 1127 (Fed. Cir. 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.”               
          Fritch, 972 F.2 at 1266, 23 USPQ2d at 1784, (citing In re                   
          Gorman, 933 F.2d 982, 987, 18 USPQ2d 1885, 1888 (Fed. Cir.

               Here, the examiner admits that Kajitani fails to “teach                
          the second set of bar codes is arranged in a horizontal row                 
          which is perpendicular to the first set of bar codes and ...                
          the incorporating of program descriptors at locations of the                
          intersections of the first set of bar codes and second set of               
          bar codes.”  (Examiner’s Answer at 4-5.)  This is an                        
          understatement.  The reference merely “shows a ... practical                
          program sheet 1 made by printing channels, dates, start times               
          and end times on a synthetic resin plate or sheet material.”                
          Col. 4, ll. 3-6.  The sheet contains no TV program                          
          descriptors.  It is merely a bar code sheet.  Fig. 4.  In
