          Appeal 97-1804                                                              
          Application 08/329,042                                                      

                    32. In response to the Final Rejection, applicant                 
          presented a second declaration of the inventor (Paper 20,                   
          Exhibit A).                                                                 
                    33. The second declaration repeats much of what                   
          is said in the first declaration, but adds (Second                          
          Declaration, ¶ 8):                                                          
               [W]hen OPC's are made by the doctor blade method as                    
               described in EXAMPLE 1 [of the specification], and by                  
               other conventional methods in the industry, the layer of               
               self-cross-linked PVB binder which results in invariably               
               continuous, non-porous, and of generally uniform                       
               thickness.                                                             

                    34. The examiner declined to give the first and                   
          second declarations much weight:                                            
                         a.   With respect to Dr. Nguyen's opinions based             
          on his observation of OPC's (Finding 25), the examiner notes                
          that Dr. Nguyen does not state the underlying basis upon which              
          he made any observation ("Whether the examination was by naked              
          eye or with an electron microscope would have a great bearing               
          on whether the layer appeared non-porous" (Examiner's Answer,               
          page 6)).                                                                   



                                       - 10 -
