Why it's free to use
- Filed August 2, 1948. Even if it was granted, its term would have ended by August 2, 1969.
- A pharmaceutical extension adds at most five years, so even that would have ended by August 2, 1974.
- We check Australian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
