  DISTRIBUTED PARALLEL PROCESSING NETWORK WHEREIN THE CONNECTION
  WEIGHTS ARE GENERATED USING STIFF DIFFERENTIAL EQUATIONS

  Inventor:  David L. Filkin
  Assignee:  E. I. du Pont de Nemours and Company

  U. S. Patent Number 5,046,020 
  Sep. 3, 1991

  Abstract.  A parallel distributed processing network of the back
  propagation type is disclosed in which the weights of connection 
  between processing elements in the various layers of the network
  are determined in accordance with the set of steady solutions of
  the stiff differential equations governing the relationship 
  between the layers of the network.

Its so nice to see people facilitating the free and unencumbered dissemination
of knowledge by borrowing pubicly distributed ideas like Backprop, modifying
them slightly and then patenting them for their own gain!
