Why it's free to use

  • Filed November 20, 1914. Even if it was granted, its term would have ended by November 20, 1935.
  • A pharmaceutical extension adds at most five years, so even that would have ended by November 20, 1940.
  • We check Australian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
