  Government under this Act, any term or condition of a contract for the sale of
  
  goods by a person to a wholesaler or retailer or any agreement between a person
  
  and a wholesaler or retailer relating to such sale shall be void insofar as it
  
  purports to establish or provide for the establishment of minimum prices to be
  
  charged on the resale of goods in India.
  
  
  (2) After the commencement of this Act, no supplier of goods whether directly

  on the resale of the goods in India.
  (3) This section shall apply to
  
  patented articles (including articles made by a patented process and articles
  
  made under any trade mark) as it applies to other goods and notice of any term
  
  or condition which is void by virtue of this section or which would be so void if
  
  included in a contract of sale or agreement relating to the sale of such
  
  article shall be of no effect for the purpose of limiting the right of a dealer
  
  to dispose of that article without infringement of the patent or trade mark, as
  
  the case may be :
  Provided that nothing in this
  
  section shall affect the validity as between the parties and their successors,
  
  of any term or condition of a licence granted by the proprietor of a patent or
  
  trade mark or by a licensee of patent or trade mark or of any assignment of a
  
  patent or trade mark, so far as it regulates the prices at which articles
  
  produced or processed by the licensee or the assignee may be sold by him.
