  (3) Where a trade mark and any part thereof

  (5) On application made in the prescribe
  
  manner by the registered proprietor of two or more trade marks registered as
  
  associated trade marks, the Registrar may dissolve the association as respects
  
  any of them if he is satisfied that there would be no likelihood of deception
  
  or confusion being caused if that trade mark were used by any other person in
  
  relation to any of the goods or services or both in respect of which it is
  
  registered, and may amend the register accordingly.
