JB this patent is attached as exhibit in Ampha's Sur-reply http://www.patents.com/us-4847338.html ( obviousness poses a pretty serious challenge to getting a PI here IMO ) btw irreparable harm IMO would be based on loss of reputation and also other incalculable damages in marketplace (Eg: not getting a FOB partner, etc) If you can calculate specific $ damages, then there is no irreparable harm.
