          Application No. 08/192,224                                                  


          23 USPQ2d at 1784 (citing In re Gordon, 733 F.2d 900, 902, 221              
          USPQ 1125, 1127 (Fed. Cir. 1984)).                                          


               Here, although Chan discloses "an underlying thin film                 
          substrate and barrier layer portion 16," col. 2, ll. 53-54,                 
          the portion is not flexible.  To the contrary, it is rigid.                 
          Specifically, "[t]he substrate and barrier layer portion 16 of              
          the thin film printhead 12 will typically consist in layer                  
          sequence of a glass or silicon substrate underlayer, a SiO2                 
          surface barrier layer, a tantalum-aluminum resistor layer, an               
          aluminum conductive trace material, a silicon nitride and                   
          silicon                                                                     
          carbide composite passivation layer, and a polyimid barrier                 
          layer such as a VACREL polymer made by the DuPont Company."                 
          Col. 3, ll. 8-15.  The examiner fails to allege, let alone                  
          show, that the addition of Barbero, Hoisington, or Nozawa                   
          cures the deficiency of Chan.                                               


               Because Chan teaches a rigid substrate and barrier layer               
          portion, we are not persuaded that teachings from the applied
