             Appeal No. 1996-4170                                                                                   
             Application 08/413,657                                                                                 


             Rather, Shair’s disclosure is limited to a defined group of polyquaternary amines. The                 
             examiner has not explained why it is reasonable to extrapolate or expand the relatively                
             narrow disclosure of Shair as has been done in the rejection.                                          
                    The decision of the examiner is reversed.
