          Appeal No. 2001-1879                                                        
          Application No. 08/919,448                                                  


               We consider first the examiner’s rejections under 35 U.S.C.            
          § 103.  Horowitz ‘955 relates to coating steel articles with a              
          composition that is similar to the one presently claimed with the           
          exception of comprising a urethane prepolymer and a peroxide.               
          Horowitz ‘811, on the other hand, while disclosing a composition            
          comprising epoxy and urethane prepolymers, as well as a peroxide,           
          is directed to coating an aluminum, not steel, substrate.  It is            
          the examiner’s position that inasmuch as Horowitz ‘955 and                  
          Horowitz ‘811 disclose compositions which protect metal surfaces            
          by grafting to the oxidized surface of the metals, it would have            
          been obvious for one of ordinary skill in the art to formulate a            
          composition comprising both epoxy and urethane prepolymers as a             
          protective coating for steel.                                               
               While the examiner’s rationale is not without logical                  
          appeal, we find that the disclosures of Horowitz ‘955 and                   
          Horowitz ‘811, in conjunction with appellants’ Declaration of               
          July 9, 1999, support the conclusion that the claimed subject               
          matter, as a whole, would have been nonobvious to one of ordinary           
          skill in the art.  Neither Horowitz ’955 nor Horowitz ‘811 is               
          directed to coating metals, in general.  Rather, Horowitz ‘955 is           




                                          4
