          Appeal No. 2002-2217                                                        
          Application 09/549,016                                                      



                                    THE REJECTION                                     
               Claims 1-3 stand rejected under 35 U.S.C. § 103 as being               
          unpatentable over Cox.                                                      
                                       OPINION                                        
               We affirm the aforementioned rejection.                                
               The appellants state that the claims stand or fall together            
          (brief, page 3).  We therefore limit our discussion to one claim,           
          i.e., claim 1, which is the sole independent claim.  See In re              
          Ochiai, 71 F.3d 1565, 1566 n.2, 37 USPQ2d 1127, 1129 n.2 (Fed.              
          Cir. 1995); 37 CFR § 1.192(c)(7)(1997).                                     
               Cox discloses a resin obtained by reacting an alkyl-                   
          substituted aniline (formula 1 in the appellants’ claim 1) with             
          formaldehyde (component A in the appellants’ claim 1) and phenol,           
          and reacting this product with a vicinal epoxide, the preferred             
          vicinal epoxide being an alkylene oxide (component B in the                 
          appellants’ claim 1) such as ethylene oxide, 1,2-epoxypropane,              
          and the epoxybutanes (col. 2, lines 36-58; col. 3, lines 58-60              
          and 65-67; col. 19, lines 39-55).  The formaldehyde and alkylene            
          oxide react with the amino group of the alkyl-substituted aniline           
          (col. 2, lines 38-41; col. 5, lines 35-43).  “The polyols can               
          have oxyalkylene chains which average from about 1.0, and lower,            
          to about 30, and higher, oxyalkylene units per reactive hydrogen            
                                          3
