Why it's free to use

  • Filed March 11, 1929. Even if it was granted, its term would have ended by March 11, 1950.
  • A pharmaceutical extension adds at most five years, so even that would have ended by March 11, 1955.
  • We check Australian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
