                 Appeal No. 95-1622                                                                                                                     
                 Application 07/890,593                                                                                                                 

                 polyester” which would have basic reactive sites (see supra note 8), and exposed to radiation energy to                                
                 adhere the coating to the substrate, such that the claimed article and that prepared in Wright Example                                 
                 22 are necessarily  or inherently, identical or substantially identical.  Wright (e.g., col. 5, line 61, to col.                       
                 6, line 2) would also have reasonably suggested to one of ordinary skill in this art that this example can                             
                 be modified to provide a coating having a substantially higher ratio of energy sensitive organometallic                                
                 groups to nucleophilic groups, and thus a greater concentration of energy sensitive organometallic                                     
                 groups that would not be involved in the crosslinking reaction, with the reasonable expectation of                                     
                 obtaining an adherent coating upon exposure to energy.                                                                                 
                          Wright further discloses Embodiment I (e.g., col. 2, lines 27-31; col. 3, lines 33-36,     col. 3,                            
                 line 45, to col. 4, line 25, col. 5, lines 43-50, col. 11, lines 5-15, and Wright Examples     1-12)                                   
                 wherein a coating of copolymers formed from a monomeric organometallic compound containing an                                          
                 energy sensitive organometallic group, a monomeric compound containing reactive nucleophilic groups                                    
                 and, optionally, a monomeric compound that does not contain either of the reactive groups, is applied to                               
                 at least a portion of one surface of a substrates having basic reactive sites and the copolymer coated                                 
                 substrate is exposed to radiation energy to form an adherent coating on the substrate.  While the overall                              
                 process is similar to Embodiments II and III, it does differ in that the copolymers coated on the                                      
                 substrate contain energy sensitive organometallic groups and reactive nucleophilic groups, and upon                                    
                 exposure to energy, the organometallic groups react with the reactive nucleophilic groups that are                                     
                 present on the same or different copolymer (col. 3, line 45, to col. 4, line 25).  Thus, in comparing                                  
                 appealed claim 2 and Wright Embodiment I, the issue that arises is whether these copolymers that are                                   
                 coated on the substrate are essentially free of reactive nucleophilic groups as we have construed this                                 
                 limitation above.  With respect to Wright Examples 1-12, we cannot determine whether the claimed                                       
                 articles and those prepared in these examples are identical or substantially identical from the information                            
                 provided by Wright.  We do observe here, as we did above, that upon exposure of the copolymers                                         
                 coating to radiation energy, the reactive nucleophilic groups will react with the organometallic groups                                
                 such that a reactive nucleophilic site can remains on the crosslinked copolymer which also contains at                                 
                 least one energy sensitive organometallic group, in similar manner to Wright Embodiments II and III,                                   
                 and thus we are again of the opinion that such a crosslinked copolymer would satisfy the limitation in                                 

                                                                        - 11 -
