               5 USPQ2d 1529, 1532 (Fed. Cir. 1988) ("Evidence that supports, rather than                   
               negates, patentability must be fairly considered.").  Therefore, we conclude                 
               that the appealed claims are patentable over the combined teachings of                       
               Kumagai and Halpern1  The rejection is reversed.

               ALEXANDRIA, VA 22314                                                                         


                                                                                                           
                      1 For the sake of completeness, we note that during oral hearing,                     
               Appellants’ counsel also argued that the Examiner had relied upon improper                   
               hindsight reasoning and, therefore, had not established a prima facie                        
               showing of obviousness.  In particular, it was noted that the Examiner failed                
               to explain why one of ordinary skill in the art, in considering the problem of               
               bisurea by-product formation, would have looked to Halpern which                             
               discloses alkoxylation of PVA, acetylation and reaction with isocyanate to                   
               produce a product which is said to be useful in the manufacture of foam                      
               products.  In addition, the Examiner did not explain why one of ordinary                     
               skill in the art would apply Halpern’s teaching relating to polyvinyl alcohol                
               particle sizes to Kumagai’s ethylene/vinyl alcohol copolymer.  We are in                     
               agreement with Appellants that the only relationship between an                              
               ethylene/vinyl alcohol copolymer and polyvinyl alcohol appears to emanate                    
               from Appellants’ disclosure.  In re Fritch, 972 F.2d 1260, 1266, 23 USPQ2d                   
               1780, 1783-74 (Fed. Cir. 1992) (“The mere fact that the prior art may be                     
               modified in the manner suggested by the Examiner does not make the                           
               modification obvious unless the prior art suggested the desirability of the                  
               modification.”).  However, we do not find this argument on the written                       
               record before us.
