          Appeal No. 2003-1801                                                        
          Application 09/559,347                                                      



          to the magnetic layer.  Specifically, the substrate of Ross must            
          be replaced with a glass or glass-ceramic substrate comprising              
          lithium.  Second, NiNb must be chosen from patentee’s many                  
          embodiments as the layer to be deposited on this replacement                
          substrate.  Third, the NiNb layer must be deposited directly onto           
          this substrate pursuant to yet another of the alternative                   
          embodiments disclosed by Ross.  Fourth, the layer must be                   
          deposited to a thickness within the here-claimed range, the                 
          obviousness of which is highly questionable at best.1  From our             
          perspective, this picking, choosing and combining of multiple               
          selected teachings in the applied prior art are the consequence             
          of impermissible hindsight rather than motivation, suggestion and           




          1 This is because the examiner’s obviousness conclusion                     
          regarding thickness is based on the proposition that thickness is           
          a result effective variable and that it would have been obvious             
          to determine optimum values for such a variable, pursuant to In             
          re Woodruff, 919 F.2d 1575, 16 USPQ2d 1934 (Fed. Cir. 1990) and             
          In re Boesch, 617 F.2d 272, 205 USPQ 215 (CCPA 1980).  However,             
          the thickness of Ross’ NiNb layer is result effective for a                 
          purpose (i.e., laser texturizing) which is completely unrelated             
          to the appellants’ claimed purpose of preventing migration of               
          lithium from the substrate to the magnetic layer.  Contrary to              
          the examiner’s inappropriate assumption, optimizing thickness               
          for  the former purpose would not necessarily yield thicknesses             
          appropriate for the latter purpose, that is, thicknesses within             
          the here-claimed range.                                                     
                                          6
