Why it's free to use

  • Filed February 10, 1959. Even if it was granted, its term would have ended by February 10, 1980.
  • A pharmaceutical extension adds at most five years, so even that would have ended by February 10, 1985.
  • We check Australian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
