Why it's free to use

  • Filed September 16, 1921. Even if it was granted, its term would have ended by September 16, 1942.
  • A pharmaceutical extension adds at most five years, so even that would have ended by September 16, 1947.
  • We check Australian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
