law: Trade Monopolies and Restrictive Trade Practices Act, 1969 
  15. Restriction of Application of Orders in Certain Cases.

  restrain any infringement of a patent granted in India, or
  
  
  (b) any person as to the condition which he attached to a licence to do
  
  anything, the doing of which but for the licence would be an infringement of a
  
  patent granted in
  
  India, or

  export goods from India, to the extent to which the monopolistic or restrictive trade
